How to buy Bitcoin and Deposit on Roobet Full Tutorial

Hello!
In this thread I will do my very best to explain how to purchase Bitcoin safely and deposit it onto Roobet.com !
If anything is too confusing or you need further instructions feel free to message a mod for help!Be very aware of other users offering to sell you bitcoin or purchase on your behalf.If you are new to Bitcoin in general I strongly recommend watching this quick video on the basics of bitcoin safety https://www.youtube.com/watch?v=2z2xggmeW1AAfter you have watched that or you already understand bitcoin skip to down below!
Buying Bitcoin
Step 1 Chosing an exchange
Ok so you want to buy bitcoin to play on roobet? No problem! Bitcoin is super easy to use once you understand it! The first thing you need to do is pick an exchange to purchase from. I would recommend coinbase as it is a very large and trusted exchange. If coinbase does not work in your region then I would recommend Binance The last option if buying online doesn't work would be a local Bitcoin ATM use google to find one close to you.

Step 2 Signing up - coinbase Sign up using https://www.coinbase.com/join/carava_zo to get a bonus 10$ btc on your first purchase Once you create an account you will be prompt to verify both a Email & Phone Number *Sometimes a photo id is required* *(It is recommend to add one as it will improve account security and increase your buying limit)* Follow the on screen prompts until you get to Add Payment Method
Add your method of payment
Once you link a Bank/Credit Card you will now be in the main page

Altcoin Explorer: NEM (XEM), the Enterprise-Grade Blockchain Platform


https://preview.redd.it/5ogfihikwkg51.png?width=1300&format=png&auto=webp&s=099780e02777d16d4e2add64b249c46da1cd488b
Nestled among the top 40 cryptocurrencies by reported market cap, New Economy Movement — popularly known as NEM (XEM) – is a peer-to-peer (P2P), dual-layer blockchain smart contract platform written in one of the most influential programming languages, Java. NEM uses the proof-of-importance (POI) consensus algorithm that essentially values the tokens held and the activity conducted by the nodes on the blockchain network.
In this Altcoin Explorer, BTCManager delves deeper into the finer intricacies of the NEM blockchain protocol, including the project’s POI consensus algorithm, its native digital token XEM, and some of its real-world use-cases.
Without further ado, let’s get to the core of this high-performance distributed ledger technology (DLT) platform.

History of NEM

NEM was launched on March 31, 2015, with an aim to develop an enterprise-grade blockchain protocol that could circumvent the infamous trilemma of blockchain: scalability, speed, and privacy.
Operated by a Gibraltar-registered NEM Group, NEM is a fork-out version of the NXT blockchain. After the successful fork, the NEM community decided to build its ecosystem from the ground up and developed its own codebase to make the network more scalable and faster.
NEM’s insistence toward building its own tech infrastructure led to a DLT protocol that is unlike anything resembling other similar platforms.
Today, NEM ranks among the top go-to blockchain platforms for enterprises across the world, rivaling competing protocols including Ethereum (ETH), and TRON (TRX), among others.

NEM’s Proof-of-Importance (POI) Algorithm

Unlike Bitcoin’s (BTC) energy-intensive Proof-of-Work (PoW) and Ethereum’s yet-to-be-implemented Proof-of-Stake (PoS) consensus algorithm, NEM uses PoI consensus mechanism.
The PoI mechanism achieves consensus by incentivizing active user participation in the NEM network. This consensus infrastructure ensures an agile decentralized network by rewarding well-behaved nodes that not only possess a significant stake in the network but are also actively engaged in executing transactions to maintain the network’s robustness.
Specifically, each node in the network possesses an ‘Importance Score’ that impacts the number of times the said node can ‘Harvest’ the XEM altcoin.
Initially, when a user puts XEM tokens into their wallet, they are called ‘unvested coins.’ Over time, as the wallets start accumulating an increasing number of XEM and contribute to the network’s transaction volume, they start collecting importance scores. At the same time, the XEM tokens in these wallets change into ‘vested coins,’ provided that there are at least 10000 tokens in the wallet.
To put things into perspective, let’s take the help of a small example.
On day 1, Joe receives 50,000 XEM in his digital wallet. Now, with each passing day, the NEM network will ‘vest’ 10 percent of the tokens held by Joe. So, on day 2, 5,000 tokens held by Joe are vested into the network. On day 3, 10 percent of the remaining tokens – 15,000 XEM – get vested into the network, leaving Joe with 13,500 XEM, and so one. After a couple of days, Joe sees that the number of XEM vested by him has crossed the 10,000 coins threshold, thereby, making him eligible to seek rewards from the NEM blockchain for his contribution to vesting his tokens.
Close followers of blockchain projects would find the aforementioned network reward mechanism bear a close resemblance to the PoS consensus algorithm. However, it’s worthy of note that vesting coins is just one way of calculating a node’s importance score.
The NEM protocol also rewards nodes that are responsible for most activity on the network. In essence, this means that the higher the number of transactions executed by a node, the more likely it is to gain higher importance points. The balance between vesting XEM and network activity is an important metric to be maintained by NEM nodes as it directly impacts their likelihood of harvesting XEM.
NEM’s consensus algorithm does away with several issues plaguing the more energy-intensive protocols such as PoW. For instance, PoI does not necessarily require high-energy hardware to run the nodes. The decentralized nature of the algorithm means that almost any machine — irrespective of its tech configuration – can participate in the NEM ecosystem ensuring it remains decentralized.

NEM’s Native Digital Token — XEM

XEM, unlike the vast majority of other cryptocurrencies, isn’t mined or staked using Pow or PoS algorithms. Rather, as explained earlier, XEM is ‘harvested’ through the PoI algorithm which ensures a steady supply of the digital token without flooding the market and involving the risk of a dramatic crash in price.
Per data on CoinMarketCap, at the time of writing, XEM trades at $0.04 with a market cap of more than $382 million and a 24-hour trading volume of approximately $6.8 million. The coin reached its all-time high of $1.92 in January 2018.
A large number of reputable cryptocurrency exchanges trade XEM, including Binance, Upbit, OKEx, Bithumb, ProBit, among others. The digital token can be easily traded with BTC, ETH, and USDT trading pairs.
That said, if you wish to vest your XEM to partake in the maintenance of the NEM network and earn rewards, it is recommended you store your tokens in the official NEM Nano wallet for desktop and mobile OS. Only XEM tokens held in the official NEM Nano wallet are eligible for vesting.

NEM Use-Cases

To date, NEM has been deployed for various real-world applications with promising results.
In 2018, Ukraine launched a blockchain-based e-voting trial leveraging the NEM DLT platform.
At the time, Ukraine’s Central Election Commission – with the local NEM Foundation representation – estimated the test vote trial in each polling station could cost as low as $1,227. The organization’s Oleksandr Stelmakh lauded the efforts, saying that using a blockchain-powered voting mechanism would make it impossible for anyone to fiddle with the records. The Commission added that the NEM protocol presents information in a more user-friendly format for voters.
In the same year, Malaysia’s Ministry of Education launched an e-scroll system based on the NEM blockchain to tackle the menace of fake degrees. The University Degree Issuance and Verification System use the NEM blockchain which is interrogated upon scanning of a QR code printed on the degree certificate.
The Ministry added that one of the primary reasons for its decision to selected the NEM platform was its unique and cutting-edge features in managing traceability and authentication requirements.
On a recent note, the Bank of Lithuania announced that it would be issuing its NEM blockchain-powered digital collector’s coin (LBCoin) in July after the successful completion of its testing phase.

Final Thoughts

Summing up, NEM offers a wide array of in-house features that separate it from other blockchain projects in a space that is becoming increasingly congested. NEM’s creative PoI consensus algorithm is a fresh take on the PoS algorithm for performance enhancement. Further, the project’s newly launched enterprise-grade DLT solution, Symbol, offers a tremendous option to businesses to help them cut costs, reduce complexities, and streamline innovation.
NEM uses the Java programming language that makes it an easy project for developers to get involved with, unlike other projects such as Ethereum that use platform-specific programming languages like Solidity. The project’s tech infrastructure not only makes it less power-intensive compared to Bitcoin but also more scalable than its rival projects including Ethereum and NEO.
NEM’s tagline, “Smart Asset Blockchain, Built for Performance,” perfectly captures everything the project has to offer. Over the years, NEM’s active developer community has craftily addressed the notorious bottlenecks in the vast majority of blockchain solutions, The future looks promising for NEM as it continues to foster a trustless and blockchain-driven economy for tomorrow.

IOTA URI scheme and metadata exchange format

The QR code in the Trinity wallet contains a string of 81 characters indicating an address. Only to people familiar to IOTA, this has a meaning and even then, no one will quickly recognize the exact length of 81 characters.
Other information in QR codes contains a URI, like a web URL, mailto, contact data in VCF, etc. Any QR code scanner will directly know what to do with that information. Even Bitcoin has a URI: https://en.bitcoin.it/wiki/BIP_0021
I think that IOTA could also benefit from having a proper URI scheme, like:
iota://pay/address/
?tag=,amount=
iota://pay/use..
iota://mam/
/read
iota://mam/
/post?message=
iota://listen/

Items in stores could then be provided with tags for automatic payment or reading of a URL with information about the authenticity.
Applications in the IOTA ecosystem can then work seamlessly together, the step to introducing IOTA can be transparent for most users and services can be built on top of IOTA more easily.
The next step would then of course be an exchange format, where distributed wallets can communicate with each other, contact data that can be exchanged over the Tangle, etc.
I think the first step to this would be a clean URI scheme, but I haven't found anything and seeing that the Trinity wallet does not even include this, I doubt that this idea was considered before. I also do not think that the community can define a good scheme, as only the IF knows what's in the pipeline and are at the forefront of standardization.
Is anyone aware of efforts in this direction or reasons why this does not seem to have been done yet?

How Blockchain.com harms the cryptocurrency community

How Blockchain.com harms the cryptocurrency community
This post has been written to draw Blockchain.com's attention to the issues of its product.
Blockchain.com (formerly Blockchain.info) was founded in 2011 and with no doubt has helped the Bitcoin community to create a block explorer and has proven itself as a valuable service. Millions of people from all over the world use their wallet. However, time goes on, Bitcoin develops, but one of the main cryptocurrency companies not only slows down the process of its development, but also discredits the usability of cryptocurrencies. Why is that? We have tried to explain that in this post.
https://preview.redd.it/i0yk7qraqkw41.jpg?width=1024&format=pjpg&auto=webp&s=963dc18551d2900bca456bfa3a6cfd3636c7c93c

1. Lack of Segwit Address Support

This is the most painful problem for our service. To receive cryptocurrency we use segwit addresses by default. If a customer contacts our support, we can of course change an address in an order to P2SH (the one that begins with number "3"), but it reduces the usability of the service. Why don't we use P2SH by default? It is less beneficial both for us and for our client, as the cost of the consolidation of the transaction is taken into account when calculating the exchange rate. With a high network load and with orders for a small amount, the commission becomes significant. To compare — segwit addresses (or Bech32 that starts with "bc1") are 15% more advantageous than P2SH.
Segwit (Segregated Witness) was activated in 2017. At the end of the same year the CEO of Blockchain.info announced its support starting from (most likely) 2018. We can understand certain fears at the beginning of the way, as the company's security system is for sure not that bad. However more than 2 years have passed since then and that is a lot for the crypto world.

2. Using Legacy (P2PKH) Addresses Only

As of now only a P2PKH address (that starts with number "1") is used in the Blockchain.com wallet to receive cryptocurrency. Why is that bad? It is unfavorable for the users of this wallet. They spend 29% more than those using P2SH addresses.

3. Confusion with PAX and USD Digital

Changing the names of the currencies from one to another only in a Blockchain.com wallet is a rather strange decision. The key problem is that nowhere in the wallet are there any clues that this is an ERC-20 PAX token on the Ethereum blockchain. New wallet users will most likely be confused by this.
We sometimes get questions: "do we have USD Digital to buy or to sell?" and our technical support is forced to explain that it is PAX.

4. Incompetence of mobile application developers

In fact, this post was inspired by this particular problem. We will not focus on performance or shortcomings, we will just tell you about the main issue.
It is worth starting with questions. What problem does a mobile application solve when a person needs to pay for something? What is the best way to fill in the recipient address and the payment amount on the smartphone? Answer: QR code.
Scanning the QR code in this application is done not just badly, but also in such a way that creates maximum number of problems for a user.
The fact is that in the Android application when scanning code with the bitcoin:
?amount=, the value of the amount to be inserted in the corresponding field may differ from the encoded value by 1-100 Satoshi! Our team simply does not understand how this was implemented.
Do not believe? Try it yourself. Amount to insert — 0.00143452 BTC
bitcoin:3LAxDr5CxwBJT4tCejV8rpAXETz7bUH3tG?amount=0.00143452
After receiving information on such a problem from our users, we began to monitor updates to this application. After 2 updates had come out, the problem was not fixed.
And what about iOS? When scanning a QR code with a sum in iOS , the sum value is simply not inserted into the field! No comments. Bravo!
Blockchain.com wallet has different currencies, not just Bitcoin. Let's try Ethereum. You want to scan QR codes for Ethereum payment with the relevant sum? There is no such possibility. The application will respond with an "Invalid address" to all such codes:
  • eth:
    ?amount=
  • ether:
    ?amount=
  • ethereum:
    ?amount=
For BitcoinCash, the task of identifying the amount in the line is also an impossible task. Line with wallet bitcoincash:qpk0689rt3xkzlw8ap4yy72amp2zpws6zujkcgavptconsidered true, but with the amount bitcoincash:qpk0689rt3xkzlw8ap4yy72amp2zpws6zujkcgavpt?amount=0.1 — "Invalid address"
But there are applications that understand all such formats, or at least one of them. The string parsing function is pretty trivial and should not be a problem for the developer.
This article has been written based on the experience of using the application of the members of our team (who have used it for many years) and our users.
We encourage Blockchain.com to fix at least 3 of the 4 problems that we covered in this article. We still hope that the company will work on the bugs and will earn back trust of its users.
In the meantime — use other applications! ;)

Altcoin Explorer: NEM (XEM), the Enterprise-Grade Blockchain Platform

Altcoin Explorer: NEM (XEM), the Enterprise-Grade Blockchain Platform

https://preview.redd.it/f82bxncaxkg51.png?width=1300&format=png&auto=webp&s=34afde717d1781f7e472c8dcacd18a8b9390a78d
Nestled among the top 40 cryptocurrencies by reported market cap, New Economy Movement — popularly known as NEM (XEM) – is a peer-to-peer (P2P), dual-layer blockchain smart contract platform written in one of the most influential programming languages, Java. NEM uses the proof-of-importance (POI) consensus algorithm that essentially values the tokens held and the activity conducted by the nodes on the blockchain network.
In this Altcoin Explorer, BTCManager delves deeper into the finer intricacies of the NEM blockchain protocol, including the project’s POI consensus algorithm, its native digital token XEM, and some of its real-world use-cases.
Without further ado, let’s get to the core of this high-performance distributed ledger technology (DLT) platform.

History of NEM

NEM was launched on March 31, 2015, with an aim to develop an enterprise-grade blockchain protocol that could circumvent the infamous trilemma of blockchain: scalability, speed, and privacy.
Operated by a Gibraltar-registered NEM Group, NEM is a fork-out version of the NXT blockchain. After the successful fork, the NEM community decided to build its ecosystem from the ground up and developed its own codebase to make the network more scalable and faster.
NEM’s insistence toward building its own tech infrastructure led to a DLT protocol that is unlike anything resembling other similar platforms.
Today, NEM ranks among the top go-to blockchain platforms for enterprises across the world, rivaling competing protocols including Ethereum (ETH), and TRON (TRX), among others.

NEM’s Proof-of-Importance (POI) Algorithm

Unlike Bitcoin’s (BTC) energy-intensive Proof-of-Work (PoW) and Ethereum’s yet-to-be-implemented Proof-of-Stake (PoS) consensus algorithm, NEM uses PoI consensus mechanism.
The PoI mechanism achieves consensus by incentivizing active user participation in the NEM network. This consensus infrastructure ensures an agile decentralized network by rewarding well-behaved nodes that not only possess a significant stake in the network but are also actively engaged in executing transactions to maintain the network’s robustness.
Specifically, each node in the network possesses an ‘Importance Score’ that impacts the number of times the said node can ‘Harvest’ the XEM altcoin.
Initially, when a user puts XEM tokens into their wallet, they are called ‘unvested coins.’ Over time, as the wallets start accumulating an increasing number of XEM and contribute to the network’s transaction volume, they start collecting importance scores. At the same time, the XEM tokens in these wallets change into ‘vested coins,’ provided that there are at least 10000 tokens in the wallet.
To put things into perspective, let’s take the help of a small example.
On day 1, Joe receives 50,000 XEM in his digital wallet. Now, with each passing day, the NEM network will ‘vest’ 10 percent of the tokens held by Joe. So, on day 2, 5,000 tokens held by Joe are vested into the network. On day 3, 10 percent of the remaining tokens – 15,000 XEM – get vested into the network, leaving Joe with 13,500 XEM, and so one. After a couple of days, Joe sees that the number of XEM vested by him has crossed the 10,000 coins threshold, thereby, making him eligible to seek rewards from the NEM blockchain for his contribution to vesting his tokens.
Close followers of blockchain projects would find the aforementioned network reward mechanism bear a close resemblance to the PoS consensus algorithm. However, it’s worthy of note that vesting coins is just one way of calculating a node’s importance score.
The NEM protocol also rewards nodes that are responsible for most activity on the network. In essence, this means that the higher the number of transactions executed by a node, the more likely it is to gain higher importance points. The balance between vesting XEM and network activity is an important metric to be maintained by NEM nodes as it directly impacts their likelihood of harvesting XEM.
NEM’s consensus algorithm does away with several issues plaguing the more energy-intensive protocols such as PoW. For instance, PoI does not necessarily require high-energy hardware to run the nodes. The decentralized nature of the algorithm means that almost any machine — irrespective of its tech configuration – can participate in the NEM ecosystem ensuring it remains decentralized.

NEM’s Native Digital Token — XEM

XEM, unlike the vast majority of other cryptocurrencies, isn’t mined or staked using Pow or PoS algorithms. Rather, as explained earlier, XEM is ‘harvested’ through the PoI algorithm which ensures a steady supply of the digital token without flooding the market and involving the risk of a dramatic crash in price.
Per data on CoinMarketCap, at the time of writing, XEM trades at $0.04 with a market cap of more than $382 million and a 24-hour trading volume of approximately $6.8 million. The coin reached its all-time high of $1.92 in January 2018.
A large number of reputable cryptocurrency exchanges trade XEM, including Binance, Upbit, OKEx, Bithumb, ProBit, among others. The digital token can be easily traded with BTC, ETH, and USDT trading pairs.
That said, if you wish to vest your XEM to partake in the maintenance of the NEM network and earn rewards, it is recommended you store your tokens in the official NEM Nano wallet for desktop and mobile OS. Only XEM tokens held in the official NEM Nano wallet are eligible for vesting.

NEM Use-Cases

To date, NEM has been deployed for various real-world applications with promising results.
In 2018, Ukraine launched a blockchain-based e-voting trial leveraging the NEM DLT platform.
At the time, Ukraine’s Central Election Commission – with the local NEM Foundation representation – estimated the test vote trial in each polling station could cost as low as $1,227. The organization’s Oleksandr Stelmakh lauded the efforts, saying that using a blockchain-powered voting mechanism would make it impossible for anyone to fiddle with the records. The Commission added that the NEM protocol presents information in a more user-friendly format for voters.
In the same year, Malaysia’s Ministry of Education launched an e-scroll system based on the NEM blockchain to tackle the menace of fake degrees. The University Degree Issuance and Verification System use the NEM blockchain which is interrogated upon scanning of a QR code printed on the degree certificate.
The Ministry added that one of the primary reasons for its decision to selected the NEM platform was its unique and cutting-edge features in managing traceability and authentication requirements.
On a recent note, the Bank of Lithuania announced that it would be issuing its NEM blockchain-powered digital collector’s coin (LBCoin) in July after the successful completion of its testing phase.

Final Thoughts

Summing up, NEM offers a wide array of in-house features that separate it from other blockchain projects in a space that is becoming increasingly congested. NEM’s creative PoI consensus algorithm is a fresh take on the PoS algorithm for performance enhancement. Further, the project’s newly launched enterprise-grade DLT solution, Symbol, offers a tremendous option to businesses to help them cut costs, reduce complexities, and streamline innovation.
NEM uses the Java programming language that makes it an easy project for developers to get involved with, unlike other projects such as Ethereum that use platform-specific programming languages like Solidity. The project’s tech infrastructure not only makes it less power-intensive compared to Bitcoin but also more scalable than its rival projects including Ethereum and NEO.
NEM’s tagline, “Smart Asset Blockchain, Built for Performance,” perfectly captures everything the project has to offer. Over the years, NEM’s active developer community has craftily addressed the notorious bottlenecks in the vast majority of blockchain solutions, The future looks promising for NEM as it continues to foster a trustless and blockchain-driven economy for tomorrow.

One Million South Koreans Now Have Blockchain Drivers Licenses

Link to Cointelegraph article: https://cointelegraph.com/news/one-million-south-koreans-now-have-blockchain-drivers-licenses
The program was only launched in May but already one million South Koreans have opted for a blockchain based license.
One million South Koreans have foregone their physical drivers license in favour of a blockchain-powered digital alternative used in conjunction with the PASS smartphone app.
This represents more than 3% of the entire driving population in South Korea, which sat at 32.6 million licensed drivers in 2019 according to Statista. This is the first authorized digital identification card to be used throughout South Korea and received approval by the nation’s Ministry of Science and ICT in September 2019.
The project was launched in May by the National Police Agency in partnership with the Korea Road Traffic Authority, and the country’s three major telecommunication providers: SK, KT and LG U+. By last month, 27 of South Korea’s driver’s license testing centres were using the PASS app to renew and reissue digital drivers licenses.
The legally recognised ID solution can also be used for identification and proof-of-age requirements, such as at convenience stores and retail chains selling cigarettes and alcohol. Users show their licence via a barcode or QR code on the app. Non-Korean residents receiving English versions of the licenses.
Other industries, including rental car and shared rides services, are also researching the ability to use these IDs as a replacement for face-to-face verification checks.

South Korea is pro blockchain

This week alone has seen South Korea announce multiple integrations of blockchain technology. Seongnam’s payment program will be expanded by issuing new digital gift certificates while beachgoers in Busan will be able to pay for services with Bitcoin (BTC) and Ethereum (ETH).
One of South Korea’s biggest banks KEB Hana Bank has partnered with the Korea Expressway Corporation to implement a blockchain-based toll system for the country’s highways.

Australia’s blockchain-based licenses

South Korea isn’t the only country to look at transitioning existing licenses to digital formats on blockchain. In late 2018, Australia’s NSW government announced the trial of Ethereum-based digital licenses which can replace physical ones.

All features that the best QR code generator should have

All features that the best QR code generator should have
QR codes have become an important part of marketing, sharing information, and adding value to the product to different products and services. From showcasing extensive information about a particular product to tracking user’s data using a dynamic QR code generator, QR codes can be your next winning digital marketing strategy.
So, how to find the best QR code generator that gets results? The Internet is filled with dozens of dynamic QR code generators each one offering something new than the others. As this post talks about the best QR code generator, we’ll talk to you through the necessary features to look into a QR code generator.
How to Choose the Best QR Code Generator?
QRTiger is your one-stop shop to all QR code needs, from Wi-Fi to Multi URL QR codes to social media channels to Emails, able to produce QR codes of any type. The must-haves of the best QR code generator are related to:
Multiple Options
Almost every QR code generator provides more than two types of QR codes. But there are a few who can get you over 10+ QR codes types. In this regard, the best QR code generator can help you create QR codes for:
· A website URL
· Multi URL redirection
· File upload as PDF
· HTML5 text editor
· WiFi
· MP3
· Bitcoin
· Vcard
· Facebook, Instagram, Pinterest, YouTube
· Email
· Text
Moreover, the ability to make multi URL QR codes sets us apart from most QR code generators available online. A multi URL QR code redirects users to multiple URLs depending on certain conditions like location, time, and device type of the user.
Credibility
Never make a mistake to use unreliable QR code generators. You are most likely to use your private information behind QR codes so using an unreliable QR code generator can put your privacy at risk. An ideal yet best QR code generator will have a high number of trusted users. This indicates the credibility of the QR code generator to perform QR code tasks with ease. It is recommended to go through user recommendations, blog comments, or reviews on the QR code generator site that you’re deciding to use.
Dynamic QR Codes
Almost all QR code generators provide the accessibility to create static QR codes. To be honest, static QR codes aren’t going to improve your marketing tactics in any way. This is where dynamic QR codes come in handy. Concerned about the difference between static and dynamic QR codes? Well, here is the difference:
· Static QR Codes: Once the information is added behind a static QR code, it cannot be changed afterward. Thus, you must create new QR codes and start all over in case you wish you to change something behind the code.
· Dynamic QR Codes: One can change the saved information in the QR codes as much as possible. This lets companies use the same QR codes to offer different deals or menus. It does not only save time but also a lot of your marketing revenue. In addition, dynamic QR codes offer real-time user tracking to devise a successful QR code campaign. You can track the total number of scans, location, time, date, and device type of the user.
As a business marketer, you might be after a dynamic QR code generator. It adds convenience and flexibility to QR code marketing. No doubt static QR codes are free, but they’re just a bunch of basic QR codes with no functionality.
Conversion Tracking
This only works for dynamic QR codes and is offered by most QR code generators. Tracking is important. If you aren’t keeping track of your QR code scans, you are most likely dumping money in the garbage and leaving a lot of sales opportunities to your competitors.
The best QR code generator with real-time conversion tracking that allows you to keep track of the total number of scans, location, time, and device type of the user. Even the exact GPS location of the scanned QR code is also possible when using QR codes in your marketing strategies.
In this way, you can analyze your targeted audience in different cities or even countries. You can analyze which of your products are getting more scans. Are they Android users or iOS users? What time do you get the highest sales? Which of your products is failing? And then come up with a winning marketing strategy to generate more sales. Sounds good? Thus, choosing a QR code generator with real-time tracking is necessary.
Multiple Designing Options
When was the last time you scanned a basic QR code with black and white squares? That was a long time ago, right? Today, QR code generators allow you to custom design your QR code per your product packaging or brand theme.
For example, you can change colors, eyes, add an image or logo, and style of your QR codes to make them look appealing on your website, products, posters, brochures, etc. With that being said, QRTIGER is able to custom design your QR codes by:
· Choosing different design patterns
· Customizing eyes at the corners
· By adding a logo or image of your brand/product

Customizing colors per your brand
Custom-Designed QR codes are more likely to get scanned than traditional QR codes. Customizing your QR code per your brand or product identity will make it stand out and offer another reason to your targeted audience to engage with your product or brand.
Different Formats
An ideal yet best QR code generator lets you print QR codes on print media to distribute among your targeted audience. For instance, if you own a restaurant, you can print dynamic QR codes on your menu to provide additional information about your restaurant i.e. origin of the restaurant recipes, and ingredients used in the food. Thereby, most QR code generators allow users to download QR codes in raster formats like JPG, SVG, PDF, PNG, etc.
Final Verdict
The best QR code generator with a logo must have the mentioned things to help you in your QR codes marketing strategy.

How can a TKEY messenger allow you to send funds anywhere in the world without commissions and in a matter of seconds?

https://preview.redd.it/fnny8lcxse651.png?width=700&format=png&auto=webp&s=cbed2ff5216eb1dc813764d99f5b12dda17a37ab
Yesterday was the official release of the new flagship product — Tkey Messenger. Messenger is available in the browser and on desktops for the most popular systems Windows, macOS, and Linux. Soon, smartphone owners will be able to try out Tkey Messenger in action, the app will appear in the App Store and Google Play.
https://preview.redd.it/f4ca4g0nue651.png?width=1400&format=png&auto=webp&s=c857c896bf71771e3d01e0210f24da9a4fb68887
In the era of rapid communication and technology development, messengers have become our default products. We use them for business purposes, to communicate with friends and acquaintances — this has long been the norm. It would seem that why are other messengers created when there are many other instant messaging systems?
Today we will talk about what a Tkey Messenger is, what it can do today, what features will be included in it in the future, and most importantly, what we are creating It for and how we will develop it.

TKEY.ME

The abbreviated name of Tkey Messenger is tkey.me. First of all, TKEY-ME is a secure messenger with p2p audio and video calls, and in the future, a built-in digital wallet.
“Every day we communicate in messengers. We earn money at work. We make purchases and transfers. We are here to combine these processes in one application and make sending funds as easy as sending a message”

The Tkey Messenger as a new ecosystem

Do you think we are here to compete with other messengers? — No, there are a lot of great messengers. We are here to create our ecosystem and the internal market in it. Combine these processes in one application and make sending funds as easy as sending a message.
After all, we work in the field of FINTECH, cryptography, and blockchain, why not apply the best practices and knowledge in practice? Therefore, the TKEY Messenger should be considered for a large ecosystem.
This is a new payment segment that covers fast communication tools in combination with an internal payment system, a set of exchange practices, blockchain, cryptography, our own experience, and the experience of global companies.

How will the Tkey Messenger ecosystem work?

https://preview.redd.it/17bml1zpue651.png?width=1400&format=png&auto=webp&s=99ebd70745968452536546fb5a59841e8f3a9c52
Let’s start with the most important thing: money should be sent in a matter of seconds, regardless of the country of issue of the Bankcard and wherever you are.

Here is a simple example:

You or your relatives live abroad and you want to send funds quickly, for example, 2600 USD — you just open a chat with your loved one, send a message and 2600 USD in the same second become available on your loved one’s account.
https://preview.redd.it/nmz4ienrue651.png?width=697&format=png&auto=webp&s=c3902fc0df1ed2eba425c3f3db3eb8c40bc7a237
It turns out that you can exchange Tkeycoin for USD, EUR, or GBP in a matter of seconds, as well as instantly send them to any place in the world and without hidden fees, the exchange amount is immediately available on the screen.
Or you have Bitcoin, and the Recipient needs dollars — Tkey Messenger will take care of all the complex tasks, you will only need to send a message to make the payment.
Each completed payment will be processed through a digital payment system without Bank intervention. You can link your Bank card to automatically withdraw digital funds to your local currency.

Do you want to simplify payments even more?

Order a TKEY card, and it will automatically be linked to your Tkey Messenger account. Make payments online, make purchases in stores — it’s just as easy as you did before, only much more convenient, faster, and safer.
https://preview.redd.it/42f1dkktue651.png?width=1400&format=png&auto=webp&s=7305192230c379c0fe81d981208a8cef8a540a5c
The most important thing is that you can easily use digital assets in combination with Fiat currencies — just top up your account in messenger to start sending currency around the world.
“Moving money around the world should be as easy and cheap as sending a message. It doesn’t matter where you live, what you do, or how much you earn.”

Send TKEY or Bitcoin via message, has it become a reality?

In Tkey Messenger, you will be able to quickly send digital currency using a message. You can not specify a public address, but send a digital currency using a message.
Instantly send funds to friends or relatives anywhere in the world. No Bank, no problems, no hidden fees.

Top up your mobile phone or pay for the Internet?

The usual payments, such as the Internet or mobile payments, will certainly be available, because if we can transfer pounds from England to Canada in a matter of seconds, and the recipient will receive dollars, why can’t we make a payment for the Internet? “Of course you can.

Transfer funds by a nickname

You don’t need to know the recipient’s account, just send funds by their nickname to the Tkey Messenger, and the funds will arrive within a few seconds. Fast, convenient, and safe.

What do we get in the future when using a Tkey Messenger?

We get an ideal payment system with instant transactions, fast access to various currencies, including digital, instant international payments, a huge platform for business, a marketplace with trusted sellers, secure transactions, while fast communication, p2p calls, and video communication. Not to mention various chips, in the format: cashback, savings account, invest. products, etc.
  • International transfers without Commission and in seconds;
  • Instant account opening — just create an account to get access to payments;
  • Access to funds 24/7/365 wherever you are.
  • Multi-currency wallet — you can use both digital currencies and classic currencies, such as the pound, euro, and dollar.
  • Payment in digital currency anywhere in the world.
  • Save time and money.

How is this possible, you say?

More than real, we will answer. At the very beginning of the project, we planned to create a marketplace, and then finalized the concept with NFC payments in TkeyPay. Smoothly, all this develops into a single system, which will be merged into a Tkey Messenger.
The Tkey Messenger is convenient and secure, payment system, and marketplace. The entire financial industry is in your hands-in your smartphone.
https://preview.redd.it/ullvuelexe651.png?width=1001&format=png&auto=webp&s=ef883fa9de067b885138a231069ddc3c0414c7d3
The mobile Finance industry is developing rapidly against the backdrop of a growing number of Internet users and the increasing role of smartphones in modern life. Today, the mobile device market attracts about 2 billion people, who remain passive players in financial markets.
With the Tkey Messenger access, you always get access to instant Finance, shopping, and the nice things you want to get here and now. In practice, it has turned out that we can often forget the keys to the apartment, rather than the phone, so your finances will always be with you.

Hello, everyone, It’s been a long time since you heard our team, someone thought we were gone, someone was waiting, and someone disappeared himself.
All this time we have worked hard to bring you good news. We will tell you what we have prepared for you, what events will be soon, what you can use right now and what else will be new in the year. And so, let’s go!

Preparing for listing on the exchange

The pandemic period played into the hands of the entire team and we managed to build beauty in our services. In anticipation of the exchange, the team tidied up the sites and services and connected new tools. First of all, we paid attention to the preparation of all services for a foreign audience, taking into account its mentality.
New sections, localizations, nice things, and much more to ensure the most efficient use of the TKEY resource. In addition to the new tabs, the services that we will talk about in this material, there is a special page for representatives of the exchange with the necessary documentation for listing — https://tkeycoin.com/en/documentation/.

Full localization

Already today the official website tkeycoin.com available in 5 languages: Russian, English, Korean, Chinese (Simplified), Chinese (Traditional).

https://preview.redd.it/xbiodqixve151.png?width=700&format=png&auto=webp&s=dd81e99cb792d62a3ebb397d2181a2f1d0de5ac8
We made adjustments to the Russian and English versions of the site, including support for Korean and Chinese for each section of the site. Professionals in their field, native speakers translated and adapted the information as it should be, and we, in turn, structured and framed it properly. So welcome!

https://preview.redd.it/hcnhws2zve151.png?width=700&format=png&auto=webp&s=30b53c5c4f3c192c39518f66941dcfdfc5b420f5
We will update language support for the site, and soon it will include support for all languages that are available in the mobile app.

QR Codes for Asian Audience


https://preview.redd.it/bv08bzm0we151.png?width=496&format=png&auto=webp&s=338ba001c3a5d6999347165e7bd725b5be7f4913
Our friends and residents of Asian countries actively use QR codes in their lives, both when paying in stores and when working with websites. QR codes are used almost everywhere when renting a car or bike, we just open the phone, scan and the mode of transport becomes available for use, anything is available for rent, even a battery, even an umbrella.
“It was a hot May day. Seven-year-old Wang Jiaozui came out of school and saw his grandfather, who came to pick him up. He was standing in the sun, and his shirt was soaked with sweat. Jiaozui invited the grandfather to buy a cold Cola in the shop, but he forgot her purse at home. It turned out that this is not important — the boy took his grandfather’s smartphone and called the payment app with a QR code on the screen.” ©
What to say if QR codes are used even to identify entire farms. By pasting QR codes on farm buildings and then scanning them, government inspectors can quickly figure out who owns the building and whether its owners are violating any laws.

We must be on the trend! Now a special library generates QR codes for the desired page, any tab on the site tkeycoin.com in Chinese and Korean-accompanied by a QR code that leads to the requested page: fast, convenient, and simple.
https://preview.redd.it/73rscop3we151.png?width=700&format=png&auto=webp&s=c83229e56d612450370b43b06910225701454c60
Providing this opportunity to our colleagues and future users of Tkeycoin from Asia is a friendly approach and most importantly, a strategic step on our part. After implementing QR codes, we are undoubtedly drawn into the convenience of this function, which we recommend to You:) If you like it, we will make QR codes on the Russian and English versions of the site.

Buying and withdrawing cryptocurrency to a Bankcard


https://preview.redd.it/9i8ykpv5we151.png?width=700&format=png&auto=webp&s=3a31d0a463de5e08f94a5b27a472fb8b53ab044e
On the site, you can now buy Bitcoin for pound, dollars, euro, and any other currency. This is a powerful automated service for instant exchange of fiat currencies for cryptocurrencies. The system works around the clock and seven days a week, allowing everyone to conduct exchanges at any time of the day and in the shortest possible time.
Withdrawal to a Bank card will be available until the end of the month, we finish the details, the page is available now, and the withdrawal itself will be activated during this week. You can buy Bitcoin, Ethereum, or any other currency right now.

https://preview.redd.it/o8z0c4b7we151.png?width=700&format=png&auto=webp&s=b4d684f09acd914316c986482b8dadf88718c618
These features are the future for the function of purchasing any product or service for TKEY at any point of sale, which will form the basis of the mobile app, quickly, conveniently, and most importantly, observing the letter of the law.
All we do is build an Empire that is being built before your eyes. Every service and product is connected, so any update promises the appearance of even more cool and effective features than before.

Buying cryptocurrency for pound, dollars, euros, and other currencies

At the end of February, we told you that we are working on building a payment service that will include the provision of services: buy cryptocurrencies, sell a cryptocurrency, withdraw cryptocurrency to Bank cards, etc.
This day has come, now you can buy Bitcoin (BTC), Ethereum (ETH), Tether USDT, Basic Attention Token (BAT), Algorand (ALGO), Tron (TRX), OKB (Token Okex.com).

https://preview.redd.it/1pm2cnv8we151.png?width=700&format=png&auto=webp&s=69473d2e5ed1b8dc75189362b46906752be29895
The purchase is available in any currency: Russian ruble, US Dollar, Euro, British pound, Ukrainian hryvnia, Indonesian rupiah, South Korean won, Japanese yen, Turkish Lira, Argentine peso.
As you can see, the currency corridors are quite extensive, which allows you to make exchanges fast and at a favorable rate. Just choose the right pair to exchange or buy, available fiat currencies: RUB, USD, EUR, GBP, UAH, IDR, KRW, JPY, TRY, ARS, available cryptocurrencies: BTC, ETH, BAT, USDT, ALGO, TRX, OKB.
Even if this wide list does not include the currency you want to buy, such as Bitcoin or USDT, it’s okay — the service will automatically convert your currency into the payment currency and the Bank will make the exchange. Exchanges take place within 1–3 minutes, it is enough to pass quick verification once, which allows you to work with a volume of > 15,000 euros per month.

https://preview.redd.it/0ln5uttawe151.png?width=700&format=png&auto=webp&s=35de9e413db35bb53f39332aa4197cd54a3e211c

Exchange of cryptocurrencies for pound, dollars, euros, and withdrawal of Bankcard

In addition to the fact that you can now easily buy a cryptocurrency for fiat currencies, pound, dollars or any other, during this week we will finish work on the withdrawal to a Bank card and you can easily withdraw your profit to the card, the most important thing is that this is a completely legal method, and all operations pass through banks and jurisdictions where work with digital assets is legalized.
This means that when you buy or make a withdrawal to the card, you get legal funds that are credited to you by the Bank or payment system.
If you are used to working with effective tools that work in a new way, or rather correctly and legally, then this service is for you. Fast crediting, easy exchange, a large selection of currency pairs, that’s what the company is betting on.
We work with the most reliable third-party partners to make your cryptocurrency process easy and convenient, and most importantly safe for You. The service supports plastic and virtual Bank cards VISA, MasterCard, MIR, and other payment systems for fast payment processing.

https://preview.redd.it/x1jnm1ccwe151.png?width=700&format=png&auto=webp&s=f86fc353ad5f207db8d233821204b521ba0b3d0e
On the exchange page, you can choose any currency pair to exchange in the opposite direction, for example, GBP to BTC or USD to BTC. Choose a suitable pair for exchange, available fiat currencies: RUB, USD, EUR, GBP, UAH, IDR, KRW, JPY, TRY, ARS, available cryptocurrencies for exchange: BTC, ETH, BAT, USDT, ALGO, TRX, OKB.
How it works
When buying cryptocurrency for the first time, your Bank reserves (holds) the requested amount, then this amount is transferred to the authorization waiting state. As soon as the Bank freezes the fiat funds, the service fixes the exchange rate at the time of creating the application, reserves the cryptocurrency, and provides you with 30–40 minutes to complete verification. After successful verification, the service charges cryptocurrency to the wallet.

Quick verification

Verification takes 2–3 minutes and requires only one time to perform operations every day. The “Know Your Customer” (KYC) procedure is necessary to exchange cryptocurrencies for fiat currencies.

https://preview.redd.it/3y0pmzrdwe151.png?width=597&format=png&auto=webp&s=01a92651b67f2df70f83082cfcd3d1fdee5491b4
As you understand, you need to pass verification 1 time, regardless of whether you withdraw funds or buy currency, after passing verification, all services are available to You without any further confirmation.

New currency

Support for other currencies, including TKEY, will be added gradually and highlighted through service updates. As for the TKEY exchange, it will become available in exchange services after listing on the exchange. Listing on an exchange allows you to automate the exchange process, link the necessary services, and most importantly, the exchange provides liquidity, which is key when we talk about exchanging for a particular currency.
We will tell you more about the operation of the service and its advantages, chips, in a separate material dedicated to the withdrawal and purchase of cryptocurrencies for fiat currencies, as well as touch on various banking issues and tell you how you can combine the SWAP service for more efficient exchange and withdrawal to the card.

Charitable activity

By making an exchange or purchase of cryptocurrency, you help children and people who need our help. We deduct 0.1% of the profit from each transaction to charity funds.
This is the fastest and most comfortable way of charity, which allows you to bring together people who are not indifferent to other people’s problems. TKEY enables people to do good deeds, and the resulting turnover profit of 0.1% is sent to charity funds every month. Together with You, we create new opportunities for people in need who need help — “Big things have small beginnings”.
How does it work?
You have made an exchange or purchase operation, the company has accumulated the volume of these operations for a month->the company has chosen a charity Fund->sent funds to the charity Fund’s account. Priority charity funds are children’s aid funds. You can always suggest a candidate for a particular Fund by sending a message to [[email protected]](mailto:[email protected]).
Why do we write Funds and not a Fund?
This is the first launch of the service, so depending on the monthly volume, we will focus on distributing funds to one charity or several. For example, if we have accumulated $ 10,000, we can distribute $ 5,000 to 2 funds. if we have accumulated $ 100, it is logical that we will only send this amount to 1 Fund. With the development of the service, we will be able to focus on several funds, which we will actively help due to the received volume.

New sections, improvements for existing services

Menu logic and site structure

The menu logic has been revised. now more items are available on the menu and they are divided into sections. Navigation through the sections has become much easier and more convenient. for some sections, QR codes are available for Russian and English-speaking audiences, and for representatives of Asian countries, all sections are available by QR code.

https://preview.redd.it/d9ntj1hfwe151.png?width=700&format=png&auto=webp&s=6c068daa450e5f824829a9457bc1bc183615f466

The market data section has been optimized for mobile apps. Charts are expanded and optimized page borders for most mobile devices, and you can search for cryptocurrencies and tokens that interest you.

https://preview.redd.it/fkuhl0vgwe151.png?width=700&format=png&auto=webp&s=67450a04bdba376da59aee1d0e5a0964c896475e

FAQ

Added answers to frequently asked questions in various sections of the site, You can find the information directly on the section page, for example, TKEY-QT, SWAP or Core. Right on the page there is a FAQ section, in which we disclose answers to questions, for example: How are You going to solve the scalability problem, or why did you choose Phoenix as the logo and symbol of the project, or how do you exchange cryptocurrency for pound or dollars? As you can see, you can get answers to different questions, depending on the topic of the site section.

https://preview.redd.it/8utkvv6iwe151.png?width=700&format=png&auto=webp&s=d493ec784d74c5982486e36fe3b4bcbcb6d57335

Footer

For convenience, the site’s footer has been expanded and new sections (quick tabs) are included, which are also available in the QR-code format. In addition to various details, the footer is now accompanied by the company’s coat of arms — the Phoenix, which is the symbol of the entire community, the Phoenix Alliance.

Page 404

Added page 404, which is also an integral part of the site. now when you go to a non-existent site page, all the necessary menu items are fully available to us, which will quickly Orient You and direct you to the desired section.

What is waiting for us in the nearest future?

In addition to various improvements, connecting services, our team has been working every day on other main areas of the Tkeycoin project, which are already being prepared for the next release and we will tell you what updates, what plans, events, and what else will be interesting this year.

Online conference with management

An online conference in question-answer format will be organized. The main task of the conference, in addition to questions and answers, is to discuss plans, talk about new directions, touch on issues of legislation, and analyze current issues of users.
The online meeting format will allow you to get feedback and discuss a large number of issues in a short time. Questions related to technical support and other questions that can be answered through the administration will not be discussed.
The meeting involves the development, constructive, and suggestions from users for further development of the Tkeycoin project. If you are interested in participating in the conference, you can also make business proposals during it, please use the time to your advantage. We work for you.

New content: reports, new categories, useful information

Based on user feedback, we introduce new categories to our content plan:
Reports This section will be accompanied by information about the work done by the team for the month, the format of submission — abstracts, highlights. This format will help establish feedback between users and developers.
Question-answer
In addition to the content that we produce ourselves, users have questions that arise during the process of working with the project’s services, as well as during interaction with the project itself. To avoid making guesses and making up stories, we have introduced the question-answer category.
Users ask questions in comments, and the company prepares answers based on the questions and they are published in the post. Depending on the number of questions, the post generates all the answers, or the post is divided into parts if the number of questions for the past period was the largest. In addition to asking questions, you can make suggestions to the project, for example, about new features or directions.
This format also builds feedback and helps to improve all services. the most important thing is that it can not only help us but also you, as the offer and questions will help you focus on the tasks that the end-user wants to see.

TKEY-POOL (Tkeycoin pool)

We are completing the work and debugging of the official pool for Tkeycoin, this is a completely new approach for mining Tkeycoin. The pool will feature higher performance and stable architecture, a light interface, and objective commissions.
A pool is a highly loaded system that works 24/7/365, it turns out that such a product hides a sufficient number of lines of code and, most importantly, is built on a reliable architecture that can withstand +50000–100000 miners, not to mention the number of connected devices for this number of miners.
A cryptocurrency pool is a combination of the hardware power of many miners at once to increase the probability of finding a block. The reward for a block obtained by the pool is distributed among all participants.
The TKEY pool is developed taking into account the features of the Tkeycoin blockchain, including multi-blockchain, transaction model, hashing, blocks, and other nuances that are an upgrade of the blockchain among others. Together with the pool, the TKEY network is being tested: high loads, attacks, and other tests that show positive results, proving that the TKEY blockchain can work under any loads and is protected from attacks.
Our task was to: 1. Stable system for handling high loads; 2. Adaptation pool for any software; 3. Connecting any hardware for mining cryptocurrency Tkeycoin; 4. Fair remuneration calculation; 5. Security.
The main goal is for any user, regardless of the software and hardware used, to be able to connect to Tkeycoin mining via a pool. The first releases will be accompanied by a simple user-friendly interface, easy connection, instructions for various mining programs that can be connected.
In future releases, we will optimize the operation of the pool, add new features, as well as tracking functions and other nice things. any suggestions from miners and the community are interesting to us and will be implemented, so do not hesitate to send your suggestions after the launch.

TKEYSPACE updates


https://preview.redd.it/fjy2dkanwe151.png?width=700&format=png&auto=webp&s=99dedd6aa59ae7eb4d585d2ef1ddae4cc6dd50f9
Work on the TkeySpace mobile app is also not standing still. We will soon release updates for TkeySpace on Android and iOS.
This release is a complete transition to the most stable version of the mobile wallet. This means that after the update, even with the largest changes, the user will not need to completely reinstall or restore to use the new features, as before, just update the app via the AppStore or GooglePlay.
Between the previous update has been a sufficient amount of time, on average, updates are released once a month. This update will be one of the major ones. We are finishing work on the code to prepare the app for the new features that will be available this year. Besides, we are improving the app’s logic, data processing speed, optimizing the code, restoring order, and preparing for the global market.

Exchange, purchase of cryptocurrency and withdrawal to the Debit/Credit Card


https://preview.redd.it/1maxjrqowe151.png?width=700&format=png&auto=webp&s=cefd5bf1ec823049eeb25640c470024a41c0430c
In addition to pleasant optimizations, the app will display the exchange and withdrawal to a Bankcard, tab with an optimized page for exchange, withdrawal, and the purchase will be available directly in the mobile app. This upgrade will also capture the cryptocurrency exchange SWAP page, which can be evaluated after the update. Other features and new features will be announced by the developers immediately after the release.

SWAP Update

The development team is finishing work on optimizing the SWAP service. Regardless of updates, it is available in working mode 24/7/365. The team is working on improving the operation, optimizing the page, changing the interfaces, improving navigation, and speeding up query processing. This update is also among the upcoming ones, along with the pool, mobile wallets, and other news that will excite.

Network Statistics

In the network statistics section, there are several sections that will be fixed — this is the hash rate of the network and the volume of Tkeycoin. Now the volume of Tkeycoin is displayed by mTKEY, and the graph itself indicates M TKEY, the user may incorrectly understand the volume of transactions in the network, so, given the current volume, it is advisable to switch the display to TKEY, and in the future switch to mTKEY for large volumes.
TKEY is divided into cryptograms (CryptoGramm, cgr), uTKEY (keys), and mTKEY. 1 TKEY = 100 000 000 cryptograms. 1 mTKEY = 100,000 cryptograms. 1 TKEY contains 1000 mTKEY. 1 mTKEY = 0.00100000 TKEY 1 uTKEY =100 cryptograms 1 TKEY contains 1,000,000 utkeys. 1 uTKEY (keys) = 0.00000100 TKEY 1 cgr = 0.00000001 TKEY

Cryptocurrency Exchange

This issue has become the cause of mass discussions, disputes, investigations, the subject of memes, kitchen, and online conversations, that just did not happen, that TKEY is not taken anywhere, someone made guesses that we are waiting for everyone to run away, or TKEY is a world conspiracy and around some actors, you can write a book or shoot a great series, not worse than Breaking Bad.
Jokes, jokes, but the question is serious. Since the 4th quarter of last year, the company has been actively working on the issue of listing, prepared the necessary platform for this, held several meetings, negotiations, released the necessary products, figured out various transfers of funds to the blockchain, worked out many small things, many major issues that were behind the scenes. Everything is ready, and it’s time to start soon. This will be a surprise, believe it or not, and we will meet you on the stock exchanges :)

What other plans does the company have?

Enabling payment at retail outlets

After entering the exchange, we will actively engage in connecting payments to implement them and link them to TKEY. The plan, strategy, and legal component are ready.

Payment development

This implies the development of payments and services that will expand the use of digital currencies in the commercial sphere. Application on the territory of Russia will depend on the Federal law on the CFA, in any case, we plan to analyze the law, after its release, to find a legal way to implement payments based on blockchain and digital assets. Therefore, until the law is released, we are keeping this initiative in the future, and we will work on other jurisdictions that will support it.
We left some plans behind the scenes, because they will make the greatest impact on the market and the value of our asset, and this — likes silence.

What useful materials will be released soon?

How to effectively use the SWAP service together with the exchange and purchase of cryptocurrency from a Bank card?

We will tell you in detail how to use these 2 services, how to save on payments and purchases, how to exchange tokens that are very difficult to exchange, how to quickly get money for them to the card, and much more.

The law CFA

Our opinion about the law of cryptocurrencies in Russia, what to pay attention to, what to prepare for, how to act if there is a complete ban. Let’s talk about legal nuances and banking practices.

TKEY blockchain

In this material, we will talk about the blockchain, analyze the issues of the system, expand the questions on attacks, payment processing, and touch on the system of multiple chains. The article suggests your suggestions, perhaps someone will have ideas that we will implement in the chain.
At the end,
Don’t forget to ask questions in the comments or send suggestions to [[email protected]](mailto:[email protected]) we will be happy to respond and consider your requests for any of our services. Collaboration, feedback, help us make the whole platform better.
Thank you for being with us! Until new meetings, stay tuned for news, updates, because the most unexpected news comes spontaneously.

Groestlcoin 6th Anniversary Release

Introduction

Dear Groestlers, it goes without saying that 2020 has been a difficult time for millions of people worldwide. The groestlcoin team would like to take this opportunity to wish everyone our best to everyone coping with the direct and indirect effects of COVID-19. Let it bring out the best in us all and show that collectively, we can conquer anything.
The centralised banks and our national governments are facing unprecedented times with interest rates worldwide dropping to record lows in places. Rest assured that this can only strengthen the fundamentals of all decentralised cryptocurrencies and the vision that was seeded with Satoshi's Bitcoin whitepaper over 10 years ago. Despite everything that has been thrown at us this year, the show must go on and the team will still progress and advance to continue the momentum that we have developed over the past 6 years.
In addition to this, we'd like to remind you all that this is Groestlcoin's 6th Birthday release! In terms of price there have been some crazy highs and lows over the years (with highs of around $2.60 and lows of $0.000077!), but in terms of value– Groestlcoin just keeps getting more valuable! In these uncertain times, one thing remains clear – Groestlcoin will keep going and keep innovating regardless. On with what has been worked on and completed over the past few months.

UPDATED - Groestlcoin Core 2.18.2

This is a major release of Groestlcoin Core with many protocol level improvements and code optimizations, featuring the technical equivalent of Bitcoin v0.18.2 but with Groestlcoin-specific patches. On a general level, most of what is new is a new 'Groestlcoin-wallet' tool which is now distributed alongside Groestlcoin Core's other executables.
NOTE: The 'Account' API has been removed from this version which was typically used in some tip bots. Please ensure you check the release notes from 2.17.2 for details on replacing this functionality.

ALL NEW - Groestlcoin Moonshine iOS/Android Wallet

Built with React Native, Moonshine utilizes Electrum-GRS's JSON-RPC methods to interact with the Groestlcoin network.
GRS Moonshine's intended use is as a hot wallet. Meaning, your keys are only as safe as the device you install this wallet on. As with any hot wallet, please ensure that you keep only a small, responsible amount of Groestlcoin on it at any given time.

ALL NEW! – HODL GRS Android Wallet

HODL GRS connects directly to the Groestlcoin network using SPV mode and doesn't rely on servers that can be hacked or disabled.
HODL GRS utilizes AES hardware encryption, app sandboxing, and the latest security features to protect users from malware, browser security holes, and even physical theft. Private keys are stored only in the secure enclave of the user's phone, inaccessible to anyone other than the user.
Simplicity and ease-of-use is the core design principle of HODL GRS. A simple recovery phrase (which we call a Backup Recovery Key) is all that is needed to restore the user's wallet if they ever lose or replace their device. HODL GRS is deterministic, which means the user's balance and transaction history can be recovered just from the backup recovery key.

ALL NEW! – GroestlcoinSeed Savior

Groestlcoin Seed Savior is a tool for recovering BIP39 seed phrases.
This tool is meant to help users with recovering a slightly incorrect Groestlcoin mnemonic phrase (AKA backup or seed). You can enter an existing BIP39 mnemonic and get derived addresses in various formats.
To find out if one of the suggested addresses is the right one, you can click on the suggested address to check the address' transaction history on a block explorer.

ALL NEW! – Vanity Search Vanity Address Generator

NOTE: NVidia GPU or any CPU only. AMD graphics cards will not work with this address generator.
VanitySearch is a command-line Segwit-capable vanity Groestlcoin address generator. Add unique flair when you tell people to send Groestlcoin. Alternatively, VanitySearch can be used to generate random addresses offline.
If you're tired of the random, cryptic addresses generated by regular groestlcoin clients, then VanitySearch is the right choice for you to create a more personalized address.
VanitySearch is a groestlcoin address prefix finder. If you want to generate safe private keys, use the -s option to enter your passphrase which will be used for generating a base key as for BIP38 standard (VanitySearch.exe -s "My PassPhrase" FXPref). You can also use VanitySearch.exe -ps "My PassPhrase" which will add a crypto secure seed to your passphrase.
VanitySearch may not compute a good grid size for your GPU, so try different values using -g option in order to get the best performances. If you want to use GPUs and CPUs together, you may have best performances by keeping one CPU core for handling GPU(s)/CPU exchanges (use -t option to set the number of CPU threads).

ALL NEW! – Electrum Personal Server

Groestlcoin Electrum Personal Server aims to make using Electrum Groestlcoin wallet more secure and more private. It makes it easy to connect your Electrum-GRS wallet to your own full node.
It is an implementation of the Electrum-grs server protocol which fulfils the specific need of using the Electrum-grs wallet backed by a full node, but without the heavyweight server backend, for a single user. It allows the user to benefit from all Groestlcoin Core's resource-saving features like pruning, blocks only and disabled txindex. All Electrum-GRS's feature-richness like hardware wallet integration, multi-signature wallets, offline signing, seed recovery phrases, coin control and so on can still be used, but connected only to the user's own full node.
Full node wallets are important in Groestlcoin because they are a big part of what makes the system be trust-less. No longer do people have to trust a financial institution like a bank or PayPal, they can run software on their own computers. If Groestlcoin is digital gold, then a full node wallet is your own personal goldsmith who checks for you that received payments are genuine.
Full node wallets are also important for privacy. Using Electrum-GRS under default configuration requires it to send (hashes of) all your Groestlcoin addresses to some server. That server can then easily spy on your transactions. Full node wallets like Groestlcoin Electrum Personal Server would download the entire blockchain and scan it for the user's own addresses, and therefore don't reveal to anyone else which Groestlcoin addresses they are interested in.
Groestlcoin Electrum Personal Server can also broadcast transactions through Tor which improves privacy by resisting traffic analysis for broadcasted transactions which can link the IP address of the user to the transaction. If enabled this would happen transparently whenever the user simply clicks "Send" on a transaction in Electrum-grs wallet.
Note: Currently Groestlcoin Electrum Personal Server can only accept one connection at a time.

Sharing my "Printed QR code" printing files used in Maracaibo, Venezuela [Requested by user]

Hello guys,
I'm the guy who usually shares information about meetups, talks and new merchants accepting BCH in Maracaibo, Venezuela. As most of you already probably noticed, the merchants I on board use a printed QR code stand to receive payments. Some users asked me where to get the format or a good website for priting BCH's QR codes, but in this case I made it myself.
Since some of you asked me about them because you want to start on boarding new merchants with the same method I do, I will share my files for anyone who wants to start on boarding and priting this QR code stands.
The file must be edited with the QR code of the merchant and the address. I will leave here a Dropbox link with the editable files (Adobe Illustrator and PDF), plus a PNG file with no address and QR code (so anyone can add it on any image-editing software).
Download link: https://www.dropbox.com/sh/y8b5c3awg2aebss/AAAHxdKRQyuYu3OS0m2Dj3VSa?dl=0
Thanks! As always, If you want to support Bitcoin Cash Maracaibo or donate me anything for sharing this, you can do it to this address: qrvc2zxljemtg57ysruxm8pd7awy8k93gv0tfy679q

Fun out-of-the-box web commands for Windows 10

No WSL required; these commands work in the command prompt without any setup whatsoever:
 finger [email protected] - a nice meteogram (also works in XP/Vista/7/8 by default) ssh redditbox.us - a CLI Reddit client ssh netris.rocketnine.space - multiplayer tetris ssh sshtron.zachlatta.com - a multiplayer Tron clone ssh [email protected] - a fun roguelike game ssh [email protected] -p 2222 - guess free minesweeper; Pass: play ssh brow.sh - a CLI internet browser (I haven't been able to click on things unless I'm running it on macOS or Linux) ssh chat.shazow.net - a chat room full of strangers ssh [email protected] - play various games including checkers curl https://tgftp.nws.noaa.gov/data/observations/metastations/KATL.TXT - METAR, replace KATL with any other ICAO curl parrot.live - a cute parrot animation curl https://icanhazdadjoke.com - shitty jokes curl pseudorandom.name - generates a random name curl dict://dict.org/d:computer - dictionary curl 12.io/ip - fetches your IP curl ipinfo.io/8.8.8.8 - fetches your geolocation 
If you enter “reg add HKCU\Console /v VirtualTerminalLevel /t REG_DWORD /d 1” then ANSI escape sequences will format correctly, which allows the following additional commands to output correctly: (and it colors the parrot)
 curl wttr.in/moon - see the current phase of the moon curl http://getnews.tech - see the top headlines curl cheat.sh - the home display for sub commands to programming resources curl cmc.rjldev.com - get coinmarketcap top 100 cryptocurrencies 
If you navigate to "Control panel -> Regional settings -> Administrative tab-> Change system locale" and activate "Beta: Use Unicode UTF-8 for worldwide language support" the following additional curl commands will also output correctly, IF you're using an advanced command line application such as Cmder or the new Windows Terminal:
 curl rate.sx - bitcoin prices curl rate.sx/[email protected] - bitcoin trend graph curl qrenco.de/STRING - replace string and generate a QR code curl wttr.in/cityname - get the weather forecast for your city curl v2.wttr.in/cityname - get a graphical weather forecast for your city 
These commands are now possible on Windows 10 since support for finger, ssh, and curl was added and enabled by default. You can setup a doskey for cmd aliases. Note that curl commands in PowerShell must be entered as curl.exe. There are also some fun telnet game servers as well as the Star Wars Episode IV ASCII movie (alternatively you can watch it with Netcat on port 23, "nc towel.blinkenlights.nl 23" which can be installed with Scoop, also try "nc rya.nc 1987") but the telnet feature must be manually enabled (run "dism /online /Enable-Feature /FeatureName:TelnetClient") and its known for being an insecure protocol. If you still choose to enable it, here's a bitcoin ticker and some fun game servers:
 telnet ticker.bitcointicker.co 10080 telnet freechess.org telnet aardmud.org telnet telehack.com telnet milek7.gq telnet mud.darkerrealms.org 2000 
I'd recommend Scoop as well as Pip (bundled with Python installation, which can be installed through Scoop and includes twitter and term2048) if you enjoyed these commands and would like more. Let me know if there's any commands that I should add to this list, I found most of them here!

Tutorial: How to receive Bitcoin donations on your Street Art works. This tutorial explains in 3 steps how to receive Bitcoin donations on your street art works:

Tutorial: How to receive Bitcoin donations on your Street Art works. This tutorial explains in 3 steps how to receive Bitcoin donations on your street art works:


Step 1 — Creating a Bitcoin Portfolio
First, it is necessary to create your wallet , which will generate your reception address (the equivalent of a bank account that belongs to you).
Thanks to this receiving address, you will be able to receive transactions in your wallet.
The Coinomiwallet is one of the easiest to use , available on Android, iOS, Windows, MacOS and Linux.
You are free to use any other wallet: Samurai Wallet , Spot , Electrum … Make sure that the wallet you choose is recognized and trusted because hacks , phishing and scams are commonplace in the world cryptocurrencies.
Download the application .

Once installed, click on “Create new wallet”.

The wallet will generate you your recovery phrase (or “Seed”, which is the private key of your wallet) which is most often a suite of 24 words.

Write down your recovery phrase by hand on a sheet of paper and keep it in a safe place (be careful to keep it private, anyone who owns this sentence becomes the owner of your funds).


Confirm to the wallet that you have correctly noted the recovery phrase and choose a password .
2nd step — Create your QR code visual
From your wallet, you need to generate your QR code of the receiving address .
Go to “Bitcoin BTC” in the wallet.

Click “Receive” (if indicated, choose a reception address “Compatibility” rather than “Default” or “Legacy”).


Bitcoin receive address example1F4bwjr74bmcXwRu53Jh27JRRCWHHd4yrz
You can now retrieve the QR code with a screenshot and save the receiving address .
To put this QR code on your works, there are 2 methods; a very simple and accessible to all (printing on paper and collage) and the second is a little more complicated (cutting stencil) but more durable:
  • The easiest way is to print the QR code on paper with the mention “Bitcoin donations” at the top and your Bitcoin receipt address at the bottom and paste it into your work.

Download this template and add your QR code and receiving address (as above). Check that the address shown corresponds to the QR code by scanning it with a smartphone.
Optional: It is recommended to add your website (or social networks) to allow people to validate that this is your Bitcoin address (and not that of a person posing as you). Of course, this same Bitcoin receiving address must appear on the front page of your site (and in your social networks profile) to allow donors to verify that the funds will be received by you.
Once the sheet is printed, you can paste it on your next street artwork. Prefer flat and smooth surfaces for better adhesion of the poster. We must make sure that it fits in with the signature of the work so that we understand that the gifts are for you.


- The second method is to create a QR code stencil and use a spray bomb to put it in your work.
There are 2 possible cutting techniques: A manual technique that requires some basic DIY. The second technique is to prepare the visual Photoshop and Illustator then to call a provider who will cut the stencil for you.
1st technique — Manual: To make yourself the stencil, you will need a rigid sheet, a cutting support, a cutting scalpel, Masking Tape, a black felt pen, a clamp and a thin square grid.
To make the QR code stencil by hand, see this tutorial .


Once the stencil of QR code is made, make a stencil with the mention “Donate Bitcoin” and add it to the first stencil to understand that this is your Bitcoin reception address. You can write it yourself or use this template (below) that you can print and overlay your rigid sheet.


Once your stencil is ready (“Donate Bitcoin” + QR code), you can put it on your next work with a black paint spray. Prefer flat, smooth and clear surfaces for a better readability of the QR code. We must make sure that the stencil is integrated into the signature of the work to understand that the gifts are for you.
2nd technique — Stencil cutting by a provider: To create a QR code stencil, it is imperative that all the background of the visual is connected to allow cutting of the stencil, for this, it is necessary to go to a site that generates QR compatible stencil code like qrcode-zebra.com


Once on the site, choose the “Text” tab and paste your Bitcoin receipt address and click on “Generate QR code”. Your QR code will appear, but the design will not be the right one. There are a few changes to make. In the “Choose patterns” tab on the left, click on the first pattern (which looks like a square grid), then in “Choose eyes”, click on the first box (the basic square “eyes”). Then, in “Set colors”, choose the color black.
Optional: if you wish to add your logo or signature, you can add it in “Add logo”. The file should be as simple as possible, in black with transparent background that connects (compatible with a stencil cut).
Now that the QR code is ready, you can retrieve it with a screenshot or click on “Dowload PNG” and give your email address to receive the QR code as a PNG file.
Then, on Photoshop, it is necessary to couple the grid of your QR code with this model so that the mention “Donations in Bitcoin” and the 3 “Eyes” square of the QR are compatible for a stencil cut. Use overlapping layers and erase old “eyes”.


Finally, download this special stencil typography and use it to enter your Bitcoin receipt address used on your QR code. Check that the address shown corresponds to the QR code by scanning it with a smartphone.
It is strongly recommended to also add your website (or social networks) to allow people to validate that this is your Bitcoin address (and not that of a person posing as you). Of course, this same Bitcoin receiving address must appear on the front page of your site (and in your social networks profile) to allow donors to verify that the funds will be received by you.
Once the visual is ready and fully compatible for stencil cutting, you can vectorize it in Illustrator and save it in EPS or AI format.
Last step, send this file to a provider who makes stencil cutting.
It’s up to you to choose the provider that best suits your location, price and time. Choose a format that suits your job. For large frescoes, larger formats (A2) are preferable, and for smaller works, smaller sizes (A4).

Once you receive the stencil, you can affix it to your next work with a black paint spray. Prefer flat, smooth and clear surfaces for a better readability of the QR code. We must make sure that it fits in with the signature of the work so that we understand that the gifts are for you.


3 — Last step, communicate.
Let all those who follow your work know that they can now support you financially by sending you Bitcoin donations on your Street Art works. You can use the means you have available, your contacts, your website, your social networks …
To help beginners, here is a tutorial that explains how to buy Bitcoin.
To track the transactions you receive, you can open your wallet regularly to see your balance.
To receive a notification when you receive a donation, you can use your Wallet to track transactions at an address of your choice.
The public can also see your balance received on your address thanks to blockchain explorers.
Here is the balance of a donation address: 3Pboy9ucGEdQUHNu2rrC6RGq4jouRc4Grb
If you receive a lot of donations, it is a good opportunity to communicate on the amount received.
Good luck and good creation!
FAQ
Why use Bitcoin?
The money you receive is 100% in your possession because you are the sole owner of your private key (recovery phrase, or “Seed”), unlike other centralized means of payment (Banks, Paypal, Ulule, Patreon. ..), Bitcoin happens totally of intermediary of confidence.
How do I use Bitcoin?
Thanks to your wallet you create a private key and a public address. The private key (recovery phrase, or “Seed”) is a bit like the key to your digital vault that you need to keep only for yourself. The public address is your RIB to receive transactions, you can share it publicly without problem.
How do I exchange my bitcoins for USD?
You can at any time send your bitcoins on an exchange online ( Coinbase …) to convert them into currency (Euro, Dollar …). You need to create an account on one of these exchange exchanges, convert your funds into the desired currency and then make a transfer to your bank account.
A faster solution may be to use a centralized service provider that offers a Bitcoin wallet connected to a credit card to spend your bitcoins directly ( Wirex , Coinbase …).

Customizing the address: Bitcoin supports several addresses formats. Most notably, regular addresses start with ‘1’, pay to script start with ‘3’ and Bech32 addresses start with ‘bc’. Some scamming sites create a QR code in the same format of the requested address, probably to escape detection if the victim lightly verifies the address. The QR code method of exporting your wallet is best suited for quickly exporting a wallet and then immediately importing it onto another device via QR code scan. If you’re switching devices and want to move your Bitcoin wallet to your new device with the Bitcoin.com wallet installed, you would select “QR Code” as your export method. Abstract. This document describes a proposed address format to be used on Bitcoin Cash. It is a base32 encoded format using BCH codes as checksum and that can be used directly in links or QR codes.. This format reuses the work done for Bech32 and is similar in some aspects, but improves on others.. Specification A QR code (quick response code) is a type of matrix barcode created in Japan back in 1994 for the Japanese automotive industry. QR codes are a machine readable label via optical scanning which contains information about just about anything you want. Most QR codes today contain information about a website URL, identifier, address, etc. Check code. The mini private key format offers a simple typo check code. Mini private keys must be generated in a "brute force" fashion, keeping only keys that conform to the format's rules. If a key is well-formed (30 Base58 characters starting with S), but fails the hash check, then it probably contains a typo.
