New to Bitcoin? Confused? Need help? You've come to the right place.

Bitcoin is an internet based decentralised currency. Similarly to Bittorrent, but Bitcoin uses a public ledger called the blockchain to record who has sent and received money. It's very new, and for many very confusing. BitcoinHelp aims to rectify this. Whether it be explaining how it works, how to use it, how to buy Bitcoins, how to integrate Bitcoins into your business. Sharing your successes as well as failures in order to help others is also gladly received. Ask away!

Was using bitcoin-qt on OSX, blockchain got corrupted and now it is impossibly big to re-download, what thin clients can I import my wallet.dat into?? OSX 10.7.5. I already tried electrum and looks like I'd have to build it from github, can't figure it out. please help.

Send help! is there a safe way I could download a torrent of the blockchain? i tried to reindex the blockchain (after my harddrive got unplugged while bitcoin-qt was running) and it looks like it would literally take a week of spinning my poor laptop fan balls out.
edit: wallet.dat is encrypted and safely backed up.

What is advantageous in downloading whole blockchain on the hard drive as in Bitcoin QT, and why does clients like Electrum get away without it?

It seems cumbersome downloading few gigs of data just to make several transactions, but I recon it has its reasons. Isn't its potentially harmful to the network if more people used Electrum? It seems kind of like leeching in the Torrent network.

I currently have some Mastercoins associated with an address held in my Bitcoin-QT client. Can I import that wallet into electrum or multibit and still have control of the Mastercoins?

Missing funds from changing Bitcoin clients from Bitcoin-qt to Electrum 1.7.2 (Details inside)

I sent all the coins from my Bitcoin-qt address to my Electrum address. The transactions show up in the blockchain (the transaction for 0.02194583 BTC) https://blockchain.info/address/169vebjzc24SQ96Rt71a2vgfY2mBgAJW6w However it does not show up in the electrum client. It is the only unconfirmed transactions that do not show up in the client so i am thinking it has something to do with that. I know its a miniscule amount of BTC its just that i get the feeling im missing something blindingly obvious and i dont want to make the same mistake with a larger quantity

Syscoin Platform’s Great Reddit Scaling Bake-off Proposal

Syscoin Platform’s Great Reddit Scaling Bake-off Proposal

https://preview.redd.it/rqt2dldyg8e51.jpg?width=1044&format=pjpg&auto=webp&s=777ae9d4fbbb54c3540682b72700fc4ba3de0a44
We are excited to participate and present Syscoin Platform's ideal characteristics and capabilities towards a well-rounded Reddit Community Points solution!
Our scaling solution for Reddit Community Points involves 2-way peg interoperability with Ethereum. This will provide a scalable token layer built specifically for speed and high volumes of simple value transfers at a very low cost, while providing sovereign ownership and onchain finality.
Token transfers scale by taking advantage of a globally sorting mempool that provides for probabilistically secure assumptions of “as good as settled”. The opportunity here for token receivers is to have an app-layer interactivity on the speed/security tradeoff (99.9999% assurance within 10 seconds). We call this Z-DAG, and it achieves high-throughput across a mesh network topology presently composed of about 2,000 geographically dispersed full-nodes. Similar to Bitcoin, however, these nodes are incentivized to run full-nodes for the benefit of network security, through a bonded validator scheme. These nodes do not participate in the consensus of transactions or block validation any differently than other nodes and therefore do not degrade the security model of Bitcoin’s validate first then trust, across every node. Each token transfer settles on-chain. The protocol follows Bitcoin core policies so it has adequate code coverage and protocol hardening to be qualified as production quality software. It shares a significant portion of Bitcoin’s own hashpower through merged-mining.
This platform as a whole can serve token microtransactions, larger settlements, and store-of-value in an ideal fashion, providing probabilistic scalability whilst remaining decentralized according to Bitcoin design. It is accessible to ERC-20 via a permissionless and trust-minimized bridge that works in both directions. The bridge and token platform are currently available on the Syscoin mainnet. This has been gaining recent attention for use by loyalty point programs and stablecoins such as Binance USD.

Solutions

Syscoin Foundation identified a few paths for Reddit to leverage this infrastructure, each with trade-offs. The first provides the most cost-savings and scaling benefits at some sacrifice of token autonomy. The second offers more preservation of autonomy with a more narrow scope of cost savings than the first option, but savings even so. The third introduces more complexity than the previous two yet provides the most overall benefits. We consider the third as most viable as it enables Reddit to benefit even while retaining existing smart contract functionality. We will focus on the third option, and include the first two for good measure.
  1. Distribution, burns and user-to-user transfers of Reddit Points are entirely carried out on the Syscoin network. This full-on approach to utilizing the Syscoin network provides the most scalability and transaction cost benefits of these scenarios. The tradeoff here is distribution and subscription handling likely migrating away from smart contracts into the application layer.
  2. The Reddit Community Points ecosystem can continue to use existing smart contracts as they are used today on the Ethereum mainchain. Users migrate a portion of their tokens to Syscoin, the scaling network, to gain much lower fees, scalability, and a proven base layer, without sacrificing sovereign ownership. They would use Syscoin for user-to-user transfers. Tips redeemable in ten seconds or less, a high-throughput relay network, and onchain settlement at a block target of 60 seconds.
  3. Integration between Matic Network and Syscoin Platform - similar to Syscoin’s current integration with Ethereum - will provide Reddit Community Points with EVM scalability (including the Memberships ERC777 operator) on the Matic side, and performant simple value transfers, robust decentralized security, and sovereign store-of-value on the Syscoin side. It’s “the best of both worlds”. The trade-off is more complex interoperability.

Syscoin + Matic Integration

Matic and Blockchain Foundry Inc, the public company formed by the founders of Syscoin, recently entered a partnership for joint research and business development initiatives. This is ideal for all parties as Matic Network and Syscoin Platform provide complementary utility. Syscoin offers characteristics for sovereign ownership and security based on Bitcoin’s time-tested model, and shares a significant portion of Bitcoin’s own hashpower. Syscoin’s focus is on secure and scalable simple value transfers, trust-minimized interoperability, and opt-in regulatory compliance for tokenized assets rather than scalability for smart contract execution. On the other hand, Matic Network can provide scalable EVM for smart contract execution. Reddit Community Points can benefit from both.
Syscoin + Matic integration is actively being explored by both teams, as it is helpful to Reddit, Ethereum, and the industry as a whole.

Proving Performance & Cost Savings

Our POC focuses on 100,000 on-chain settlements of token transfers on the Syscoin Core blockchain. Transfers and burns perform equally with Syscoin. For POCs related to smart contracts (subscriptions, etc), refer to the Matic Network proposal.
On-chain settlement of 100k transactions was accomplished within roughly twelve minutes, well-exceeding Reddit’s expectation of five days. This was performed using six full-nodes operating on compute-optimized AWS c4.2xlarge instances which were geographically distributed (Virginia, London, Sao Paulo Brazil, Oregon, Singapore, Germany). A higher quantity of settlements could be reached within the same time-frame with more broadcasting nodes involved, or using hosts with more resources for faster execution of the process.
Addresses used: 100,014

It is important to note that this POC is not focused on Z-DAG. The performance of Z-DAG has been benchmarked within realistic network conditions: Whiteblock’s audit is publicly available. Network latency tests showed an average TPS around 15k with burst capacity up to 61k. Zero-latency control group exhibited ~150k TPS. Mainnet testing of the Z-DAG network is achievable and will require further coordination and additional resources.
Even further optimizations are expected in the upcoming Syscoin Core release which will implement a UTXO model for our token layer bringing further efficiency as well as open the door to additional scaling technology currently under research by our team and academic partners. At present our token layer is account-based, similar to Ethereum. Opt-in compliance structures will also be introduced soon which will offer some positive performance characteristics as well. It makes the most sense to implement these optimizations before performing another benchmark for Z-DAG, especially on the mainnet considering the resources required to stress-test this network.

Cost Savings

Total cost for these 100k transactions: $0.63 USD
See the live fee comparison for savings estimation between transactions on Ethereum and Syscoin. Below is a snapshot at time of writing:
ETH price: $318.55 ETH gas price: 55.00 Gwei ($0.37)
Syscoin price: $0.11
Snapshot of live fee comparison chart
Z-DAG provides a more efficient fee-market. A typical Z-DAG transaction costs 0.0000582 SYS. Tokens can be safely redeemed/re-spent within seconds or allowed to settle on-chain beforehand. The costs should remain about this low for microtransactions.
Syscoin will achieve further reduction of fees and even greater scalability with offchain payment channels for assets, with Z-DAG as a resilience fallback. New payment channel technology is one of the topics under research by the Syscoin development team with our academic partners at TU Delft. In line with the calculation in the Lightning Networks white paper, payment channels using assets with Syscoin Core will bring theoretical capacity for each person on Earth (7.8 billion) to have five on-chain transactions per year, per person, without requiring anyone to enter a fee market (aka “wait for a block”). This exceeds the minimum LN expectation of two transactions per person, per year; one to exist on-chain and one to settle aggregated value.

Tools, Infrastructure & Documentation

Syscoin Bridge

Mainnet Demonstration of Syscoin Bridge with the Basic Attention Token ERC-20
A two-way blockchain interoperability system that uses Simple Payment Verification to enable:
  • Any Standard ERC-20 token to be moved from Ethereum to the Syscoin blockchain as a Syscoin Platform Token (SPT), and back to Ethereum
  • Any SPT to be moved from Syscoin to the Ethereum blockchain as an ERC-20 token, and back to Syscoin

Benefits

  • Permissionless
  • No counterparties involved
  • No trading mechanisms involved
  • No third-party liquidity providers required
  • Cross-chain Fractional Supply - 2-way peg - Token supply maintained globally
  • ERC-20s gain vastly improved transactionality with the Syscoin Token Platform, along with the security of bitcoin-core-compliant PoW.
  • SPTs gain access to all the tooling, applications and capabilities of Ethereum for ERC-20, including smart contracts.

API

Tools to simplify using Syscoin Bridge as a service with dapps and wallets will be released some time after implementation of Syscoin Core 4.2. These will be based upon the same processes which are automated in the current live Sysethereum Dapp that is functioning with the Syscoin mainnet.

HOWTO: Setup an Agent
Developer & User Diligence

Trade-off

The Syscoin Ethereum Bridge is secured by Agent nodes participating in a decentralized and incentivized model that involves roles of Superblock challengers and submitters. This model is open to participation. The benefits here are trust-minimization, permissionless-ness, and potentially less legal/regulatory red-tape than interop mechanisms that involve liquidity providers and/or trading mechanisms.
The trade-off is that due to the decentralized nature there are cross-chain settlement times of one hour to cross from Ethereum to Syscoin, and three hours to cross from Syscoin to Ethereum. We are exploring ways to reduce this time while maintaining decentralization via zkp. Even so, an “instant bridge” experience could be provided by means of a third-party liquidity mechanism. That option exists but is not required for bridge functionality today. Typically bridges are used with batch value, not with high frequencies of smaller values, and generally it is advantageous to keep some value on both chains for maximum availability of utility. Even so, the cross-chain settlement time is good to mention here.

Cost

Ethereum -> Syscoin: Matic or Ethereum transaction fee for bridge contract interaction, negligible Syscoin transaction fee for minting tokens
Syscoin -> Ethereum: Negligible Syscoin transaction fee for burning tokens, 0.01% transaction fee paid to Bridge Agent in the form of the ERC-20, Matic or Ethereum transaction fee for contract interaction.

Z-DAG

Zero-Confirmation Directed Acyclic Graph is an instant settlement protocol that is used as a complementary system to proof-of-work (PoW) in the confirmation of Syscoin service transactions. In essence, a Z-DAG is simply a directed acyclic graph (DAG) where validating nodes verify the sequential ordering of transactions that are received in their memory pools. Z-DAG is used by the validating nodes across the network to ensure that there is absolute consensus on the ordering of transactions and no balances are overflowed (no double-spends).

Benefits

  • Unique fee-market that is more efficient for microtransaction redemption and settlement
  • Uses decentralized means to enable tokens with value transfer scalability that is comparable or exceeds that of credit card networks
  • Provides high throughput and secure fulfillment even if blocks are full
  • Probabilistic and interactive
  • 99.9999% security assurance within 10 seconds
  • Can serve payment channels as a resilience fallback that is faster and lower-cost than falling-back directly to a blockchain
  • Each Z-DAG transaction also settles onchain through Syscoin Core at 60-second block target using SHA-256 Proof of Work consensus

Z-DAG White Paper
Useful read: An in-depth Z-DAG discussion between Syscoin Core developer Jag Sidhu and Brave Software Research Engineer Gonçalo Pestana

Trade-off

Z-DAG enables the ideal speed/security tradeoff to be determined per use-case in the application layer. It minimizes the sacrifice required to accept and redeem fast transfers/payments while providing more-than-ample security for microtransactions. This is supported on the premise that a Reddit user receiving points does need security yet generally doesn’t want nor need to wait for the same level of security as a nation-state settling an international trade debt. In any case, each Z-DAG transaction settles onchain at a block target of 60 seconds.

Syscoin Specs

Syscoin 3.0 White Paper
(4.0 white paper is pending. For improved scalability and less blockchain bloat, some features of v3 no longer exist in current v4: Specifically Marketplace Offers, Aliases, Escrow, Certificates, Pruning, Encrypted Messaging)
  • 16MB block bandwidth per minute assuming segwit witness carrying transactions, and transactions ~200 bytes on average
  • SHA256 merge mined with Bitcoin
  • UTXO asset layer, with base Syscoin layer sharing identical security policies as Bitcoin Core
  • Z-DAG on asset layer, bridge to Ethereum on asset layer
  • On-chain scaling with prospect of enabling enterprise grade reliable trustless payment processing with on/offchain hybrid solution
  • Focus only on Simple Value Transfers. MVP of blockchain consensus footprint is balances and ownership of them. Everything else can reduce data availability in exchange for scale (Ethereum 2.0 model). We leave that to other designs, we focus on transfers.
  • Future integrations of MAST/Taproot to get more complex value transfers without trading off trustlessness or decentralization.
  • Zero-knowledge Proofs are a cryptographic new frontier. We are dabbling here to generalize the concept of bridging and also verify the state of a chain efficiently. We also apply it in our Digital Identity projects at Blockchain Foundry (a publicly traded company which develops Syscoin softwares for clients). We are also looking to integrate privacy preserving payment channels for off-chain payments through zkSNARK hub & spoke design which does not suffer from the HTLC attack vectors evident on LN. Much of the issues plaguing Lightning Network can be resolved using a zkSNARK design whilst also providing the ability to do a multi-asset payment channel system. Currently we found a showstopper attack (American Call Option) on LN if we were to use multiple-assets. This would not exist in a system such as this.

Wallets

Web3 and mobile wallets are under active development by Blockchain Foundry Inc as WebAssembly applications and expected for release not long after mainnet deployment of Syscoin Core 4.2. Both of these will be multi-coin wallets that support Syscoin, SPTs, Ethereum, and ERC-20 tokens. The Web3 wallet will provide functionality similar to Metamask.
Syscoin Platform and tokens are already integrated with Blockbook. Custom hardware wallet support currently exists via ElectrumSys. First-class HW wallet integration through apps such as Ledger Live will exist after 4.2.
Current supported wallets
Syscoin Spark Desktop
Syscoin-Qt

Explorers

Mainnet: https://sys1.bcfn.ca (Blockbook)
Testnet: https://explorer-testnet.blockchainfoundry.co

Thank you for close consideration of our proposal. We look forward to feedback, and to working with the Reddit community to implement an ideal solution using Syscoin Platform!

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.

How to Upgrade?

Windows
If you are running an older version, shut it down. Wait until it has completely shut down (which might take a few minutes for older versions), then run the installer.
OSX
If you are running an older version, shut it down. Wait until it has completely shut down (which might take a few minutes for older versions), run the dmg and drag Groestlcoin Core to Applications.

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.

I'm tired of bitcoin-qt

Mini rant. I was happy using bitcoin-qt for quite a few months now, It had gave me a few headaches, sometimes the database was corrupted or something, just re-index it. It worked fine.
I always exit bitcoin-qt before shutting down the computer, to never let this happen again, but it happens from time to time.
Anyway, five days ago, it started again with the database problem. I tried to reindex it, delete last blocks and reindex it, nothing was working. So, OK, screw it, delete all (except wallet file) and let download the whole blockchain again. ... Well... it stopped syncing after a while. It tells me that I need to update the client. Other times I it tells me it's syncing, but it shows a 0 blocks indexed (and no arrows icon on bottom-right).
After 5 days, I just delete everything (again) and started from 0.
I don't like the idea of thin client, but for the moment I've downloaded MultiBit, I read that Armory works on top of bitcoin-qt, should I try it or I will have the same problems?
I know this is my problem, not a problem with bitcoin-qt itself, it worked very good for months. I don't think it's a network problem (I have a good connection), not a software problem (Debian Squeeze), as I said, I exit the program before the computer. Just a mini-rant about all this.
I'm also concerned this happens to less techie people, they could easily delete the wallet file, or just get tired of bitcoins because of similar problems with the programs.

A little late for Moronic Monday: Is there any real benefit to using a thin Bitcoin wallet as opposed to using the default fat one?

I downloaded Electrum to a friend's computer, gave her some bitcoin for her birthday. I was very pleased with the simplicity of it and no day-long blockchain download. Currently I have the official bitcoin-qt wallet for windows.
Thanks for any help!

I think I'm being abused by a blockchain...

Sorry if this is stupid, but someone tipped me $0.42 of bitcoins... thats kind and fun so I downloaded a wallet and its synching (and has been since the beginning of time).
My understanding is that the blockchain I need is 11-12 gb.
Am I seriously downloading 12 gb ($6.00 worth of internets) in order to hold my $0.42 cents?
Thanks!
Edit: I have successfully bumped my magic internet money into a 'lite' wallet. Thanks for all the help guys, honestly I'm shocked at how bloody active and helpful you guys are!

Trying to get back into the game... a dumb question...

I haven't opened up my btc client in several months. I've used the Satoshi client since the beginning. I had done this once before, and my laptop was essentially out of commission, cpu at 100% for several days while the blockchain updated.
Any way to avoid that huge in app blockchain dl, at least at the front end? I'd like to get my client updated, the move to a light client like electrum or something.

How do I get all transaction data for a specific address?

My primary bitcoin address now has nearly 3000 transactions associated with it.
blockchain.info and blockexplorer.com don't seem to want to deal with addresses with this much history.
I don't really blame them, that's a lot of data to parse.
I'm running bitcoin-qt on Windows right now. It is fully-synchronized with the whole blockchain.
Is there a way for me to somehow query my computer's data? I'd like to be able to do something simple like sending a request for all transactions associated with a particular address.
I'm comfortable using javascript, C# and a few other languages.
What's my best option here?

My wallet is out of sync by over 3 years, why?

Hi, I just recently got a bitcoin wallet.
I bought just under 0.1 BTC earlier and I was waiting for it to appear in my wallet but realised it was out of sync by 3 years and 14 weeks.
It doesn't appear to be snycing, how do I make it sync so I can check my BTC has been delivered?

What is the best client to use for storing bitcoins, and is it worth making a paper wallet?

I have recently put a good amount of money into bitcoins, and I just want to make sure that all my coins are safe and backed up properly. According to this site it looks like bitcoin-QT is the way to go, but what are your recommendations?

Hacked (offline) wallet? What the hell?

This is getting awkward.
Last night, 31st of March, 21:32 (GMT +1) 0.5602 BTC were transferred to "1FmMasfuEE6wtpzdWiVnDynfJ5tyyVbhP3". This was almost 100% what was stored in said wallet.
I have full AV, there's 0 spy and/or malware on this computer. What the hell?!
Please help me and look out for that address..

Transcript of Open Developer Meeting in Discord - 5/31/2019

[Dev-Happy] Blondfrogs05/31/2019
Hey everyone. I have opened the channel. So us peeps can talk :smiley:
Hans_Schmidt05/31/2019
Hello !
Tron05/31/2019
Hey all!
I've been on different high-priority project for Medici for last few weeks, but that should wrap up Monday and then I can spend more time on Ravencoin.
Thanks to Scotty for working on BlockBook which was needed for more wallets.
Hans_Schmidt05/31/2019
Good opening. I was going to ask- The last ravend/qt develop Github commit was on May 3rd. Can anyone comment on when work is planned to resume on?
Tron05/31/2019
@[Dev-Happy] Blondfrogs has been working tirelessly on Tags and Restricted Assets.
It is coming along nicely.
It is going to need lots of testing.
Just because there's been lots of changes.
[Dev-Happy] Blondfrogs05/31/2019
@Hans_Schmidt I have moved to my personal github with changes. You can check out my repo on the branch tags to view the latest commits
Tron05/31/2019
Topic: 12-words and time
One of the issues with 12-words on the mobile wallet is that it needs to scan the blockchain to find funds when recovering a wallet.
One proposed idea is to include additional info (optional) like a number that represents the number of weeks since Jan 3, 2009 to start scanning the chain.
Hans_Schmidt05/31/2019
@[Dev-Happy] Blondfrogs I looked at tags. tags last commit was 4/26. Is that correct?
Tron05/31/2019
Another proposal would be to use some of the bits in the 128 bits of entropy generated as a number (instead of entropy).
[Dev-Happy] Blondfrogs05/31/2019
yep. that is correct. I have been working on the Qt element of it, to hopefully aid with testing.
Great idea @Tron
Tron05/31/2019
Example: <96 bits entropy> + <32 bits timestamp>
Or <128 bits entropy> which is the seed and encoded into 12-words, and then a number like 5212 for how many weeks after Jan 3, 2009 to start scanning the chain. This would just speed things up.
Thoughts everyone?
Thoughts anyone?
[Dev-Happy] Blondfrogs05/31/2019
I love it.
Link05/31/2019
It seems a good idea.
ParabolicAssoil - HODL COACH05/31/2019
Pretty smart. I am wondering how Electrum handles it and why we can't use that method. I assume it doesn't work for assets?
[Dev-Happy] Blondfrogs05/31/2019
Most Electrum wallets are light wallets, and don't use the same syncing method that our breadcore wallet uses
Tron05/31/2019
Electrum doesn't work for assets.
Hans_Schmidt05/31/2019
Why does it have to be part of the word seed. Then you have to remember it like a key derivation path. Why not just have the gui ask at what date to start scan?
Tron05/31/2019
Either method of encoding would work and be compatible with any BIP44. With the extra number, you'd ignore it for Coinomi, or JAXX. With the encoding the time into the 12 words, there'd be no change, but you'd lose 32 bits of entropy. 4 Billion times less secure if you knew exactly when the wallet was created.
@Hans_Schmidt That's also an option.
ParabolicAssoil - HODL COACH05/31/2019
Thanks for the answers, gentlemen
Hans_Schmidt05/31/2019
The long term solution in bitcoin for faster more secure SPV is Neutrino protocol.
Tron05/31/2019
What's Neutrino protocol?
Hans_Schmidt05/31/2019
Complicated replacement for bloom filters but has some bitcoin-core pull requests already and being pushed by the Lightning folks.
Tron05/31/2019
Thanks. I'll read about it this weekend.
Hans_Schmidt05/31/2019
For what you need, a gui question is MUCH simpler
[Dev-Happy] Blondfrogs05/31/2019
So @Tron for the 12 words there are two options we are talking about.
  1. Using 12 words in addition to a timestamp to help the mobile wallets sync faster?
  2. Using some about of words and a timestamp to create the private key?
Is this correct>?
Both accomplish the same thing, just implemented in the different way. Faster sync for mobile wallets
traysi05/31/2019
What's the status on messaging?
[Dev-Happy] Blondfrogs05/31/2019
Messaging is complete, we are wrapping it up with the restricted assets release. I am currently buiding the QT gui elements needed for both restricted assets, and messaging.
Tron05/31/2019
@[Dev-Happy] Blondfrogs Yes. They do the same thing. One option potentially reduces security of the 128-bit seed. The other requires writing down an extra number that is optional. 12-words + [optional number] Where the [optional number] just clues in the wallet as to when to start syncing the chain without it having to reference an API.
[Dev-Happy] Blondfrogs05/31/2019
Thanks, If it was me, I would want to not change to many critical elements of the BIP44 protocol so that we can still utilize all current existing packages and libraries that support it.
Hans_Schmidt05/31/2019
Mobile sync- Stay standard Messaging- From what I could tell, at protocol level Message and Memo are the same. Is that correct?
[Dev-Happy] Blondfrogs05/31/2019
Yes.
Tron05/31/2019
Message and memo are the same. The only difference is how the message/memo is interpreted by the clients.
Hans_Schmidt05/31/2019
Thanks
Tron05/31/2019
A memo that is attached to a tx that sends back to origin (for an owner token) is a message that will be displayed by clients. If the client has some of that token.
Sminem05/31/2019
I just came here to say i love you all and keep it up. And also that we are all going to make it bruhs
Hans_Schmidt05/31/2019
Makes sense
𝕿𝖍𝖊 𝕯𝖔𝖓 𝕳𝖆𝖗𝖎𝖘𝖙𝖔 CEO ∞05/31/2019
i got my barber to my some RVN
i did my part
Tron05/31/2019
@Hans_Schmidt Messages make sense or that Sminem loves us all?
Sminem05/31/2019
both
Hans_Schmidt05/31/2019
Yup:smiley:
theking05/31/2019
I know there are a lot of moving parts right now, but what is the current ETA on restricted assets and tags going to testnet?
[Dev-Happy] Blondfrogs05/31/2019
Currently the protocols are complete. However, to make testing easier for the average user, we are working on basic Qt functionality before we will release.
I would say 1-2 weeks of development on the QT side, and we will be ready for testnet
Sminem05/31/2019
What is situation with dividends, i'm dumb
we had BW develop it but he cannot anymore due lack of time
Tron05/31/2019
We will need to re-assign it or do it next.
Sminem05/31/2019
sorry if it has been asked
okey
Tron05/31/2019
No, excellent question.
[Dev-Happy] Blondfrogs05/31/2019
I have been working with a member of the community that has been implementing dividends.
Sminem05/31/2019
nicee
[Dev-Happy] Blondfrogs05/31/2019
I will have more info on that next week
CryptokittyPizzaBoi JON.NETWORK05/31/2019
How is voting coming along?
[Dev-Happy] Blondfrogs05/31/2019
voting was pushed back in order to work on restricted assets.
So voting will be the next phase after testing of the latest build makes it to mainnet
Chill05/31/2019
Just wanted to randomly add that you all rock! It can't be said enough
theking05/31/2019
Awesome news on the timing @[Dev-Happy] Blondfrogs
[Dev-Happy] Blondfrogs05/31/2019
yes sir :smiley:
Any other questions we might be able to answer for you peeps?
Hans_Schmidt05/31/2019
I haven't tried to test tags branch (restricted) on testnet because that would be another fork in a sea of forks. A pre-gui messaging+restricted "official" release would be helpful
[Dev-Happy] Blondfrogs05/31/2019
Yeah, we can do that. I will work on that start this next week. and hopefully we can release testnet sooner.
Hans_Schmidt05/31/2019
Great.
Tron05/31/2019
Any tooling, or 2nd level stuff that's missing that is needed?
[Dev-Happy] Blondfrogs05/31/2019
There are a couple things missing that will help view data but all protocols and consensus should be working and testable
john mclaine05/31/2019
I just want to thank you, and tell you that my contribution will be to write an article in French detailing the entire RAVENCOIN project and its perspectives. IN CODE WE TRUST
[Dev-Happy] Blondfrogs05/31/2019
sounds good @john mclaine
I think we are going to call it for today everyone. Sneak in some questions if you have them in the next minute or so
Tyrantt05/31/2019
Hey guys, I've been around since late Jan 2017 and just want to say that you guys rock. I haven't been following as much lately since I've been busy with life, but was wondering if there is a guesstimation on when the roadmap will be completed
[Dev-Happy] Blondfrogs05/31/2019
Hopefully end of 2019. A nice little holiday miracle.
Daveatt05/31/2019

How do you import a Bitcoin Core (QT)-made wallet.dat file into another wallet?

So I have a wallet.dat made a while ago and wanted to check what was in it, problem is it was made in the bitcoin core QT client, which I can't even load up because it occasionally freezes and usually won't even sync up, at an absurdly slow rate.
When I replace that wallet file into the default data directory, and start bitcoin-qt.exe with the -rescan command, it just starts but no addresses show up in my wallet file and i noticed the wallet.dat file size changes when the bitcoin core client starts up, seemingly modifying something to make it slightly bigger, don't know why.
How do I check this wallet.dat? I tried importing it into the latest electrum 3.2.3 wallet and it won't accept it.

Two-factor authentication (2FA) is a way to add additional security to your wallet. The first 'factor' is your password for your wallet. The second 'factor' is a verification code retrieved via text message or from an app on a mobile device. 2FA is conceptually similar to a security token device that banks in some countries require for online banking. Electrum Bitcoin Wallet. Impressum This website is hosted by Electrum Technologies GmbH Electrum Technologies was founded by Thomas Voegtlin in 2013. Its mission is to develop, package and distribute Electrum software, and to provide services to Bitcoin users and businesses. Electrum is a pure python application. If you want to use the Qt interface, install the Qt dependencies: sudo apt-get install python3-pyqt5 If you downloaded the official package (tar.gz), you can run Electrum from its root directory, without installing it on your system; all the python dependencies are included in the 'packages' directory. 1. Install Bitcoin-Qt Since version 0.9, Bitcoin-Qt was renamed to Bitcoin Core t o reduce confusion between Bitcoin-the-network and Bitcoin-the-software. Bitcoin Core is a full Bitcoin client. It is a thick client, meaning it requires the full blockchain (explained below) on local disk to operate and expose blockchain back to the network to help relay and verify transactions. With Electrum you can make use of a compromise solution: Store the wallet on your PC. Carry out transactions by connecting to remote servers. Electrum doesn't download the block chain. By downloading Electrum to your PC you'll have a lightweight and secure Bitcoin client.
