April brought a variety of news for the BTG community. Some, we did not plan – like when Binance added new BTG trading pairs, and then added BTG margin trading. Others were totally our doing – like when we published our updated Roadmap for 2021.

The new Roadmap has generated a lot of questions… and we’d like to provide a lot of answers. So, to make it easier for folks, we’re holding our first self-hosted AMA on our Discord server this upcoming Saturday.

 

Join us Saturday for an hour at 13:00 UTC and ask us anything!

That’s 9:00 NYC, 14:00 London, 16:00 Moscow, 21:00 Beijing.

You can also join us ahead of time to submit questions to be answered in the first half hour; the second half will be for followups and new questions.

BTG Roadmap 2021 https://btgofficial.org/btg-roadmap-2021/ Tue, 27 Apr 2021 00:30:58 +0000 https://btgofficial.org/?p=41165

The Course Ahead

At inception, Bitcoin Gold was focused on providing a cryptocurrency in the Bitcoin model, but which was more decentralized for miners. Today, our focus is on making BTG a more trustless and useful cryptocurrency for everyone, and that change in focus is evident in our current development roadmap.

While we’ve always been broadly pro-crypto and believed in collaboration, the push to improve usability and usefulness entails a push towards interoperability. This means adapting so that BTG can be used with the best smart contract protocols; it means pooling security from bigger chains and offering it to smaller chains; it means making BTG, and BTG’s value, accessible throughout the smart-contract ecosystem, leveraging their security models as well as their technical capabilities: it means creating more value for everyone.

The development items on our current roadmap fall into four general areas:

Interoperability: things which grant or enhance the ability for BTG to interact bidirectionally with other blockchains and blockchain ecosystems, like Polkadot and Ethereum. Work on the bridge to Phala Network is already underway.

Applications: things which can be done after that interoperability is established. These hint at what’s possible, but need to wait until Interoperability comes to life. One notable item here: we plan to gradually shift from our traditional Board-based governance structure to a modern DAO-based model, which we expect to bring new people into the governance process and to help decentralize management of the chain and the project.

Infrastructure: these are core items in the BTG tech stack which need updates and refreshers. These are already underway, and some are very near completion, like new version(s) of our explorers, and a very-updated version of ElectrumG.

Lightning Network: establishing a robust and effective LN as a layer-2 solution is still very much on our development agenda, although current transaction volumes and fees don’t necessitate a solution at the moment. We want to build up the infrastructure and, most importantly, the user tool set, for an effective and easy-to-use LN before it becomes a critical need to alleviate transaction fee concerns and allow people to continue to make micropayments.

Here are all the things we’re currently doing or planning to do:

Bitcoin Gold Roadmap 2021

Interoperability

BTG-Polkadot Bridge: we’re building a lightweight BTG-Polkadot Bridge based on a Phala Bridge solution, built in partnership with Phala Network. This will enable cross-chain transactions between BTG and Phala, and leads to BTG gaining access to advanced blockchain functions like smart contracts, DeFi protocols, on-chain governance, and eventually connect to external blockchains like Ethereum.

Bridged ERC20/Wrapped Token: we’re creating a trustless wrapped token (like WBTC) through the cross-chain bridge, and making it accessible in the Polkadot and Ethereum DeFi ecosystems. This depends on the BTG-Polkadot Bridge.

Smart Contract Integration: we’ll connect BTG to smart-contract-enabled blockchains on Polkadot and / or Ethereum, allowing wide use cases to be developed for BTG. This depends on the Bridged ERC20/Wrapped Token.

Confidential Smart Contracts: integrating with Phala Network’s Confidential Smart Contracts to provide on-chain confidentiality. This depends on the BTG-Polkadot Bridge.

Applications

BTG for DEX: we’ll work to establish BTG trading pairs on a well-known DEX (e.g. Uniswap) and bootstrap liquidity, making BTG more accessible and attracting more liquidity around the world. This depends on the Bridged ERC20/Wrapped Token.

BTG for Lending: we’ll list BTG as a lending asset on well-known lending platforms (e.g. Aave) and bootstrap liquidity. This will empower investors and miners to better plan and utilize their BTG income. This depends on the Bridged ERC20/Wrapped Token.

DAO On-chain Governance: we’ll build a DAO structure as a smart contract to replace the current governance model. This will take time, but the intent is to fully move the Endowment and any future project income to the DAO for budget management. We also hope for this to open governance to the community to participate in development, decision making, and spending actions. This depends on Smart Contract Integration.

Infrastructure

CCBN: we’re committed to fully Implementing CCBN – first as an add-on script, and later as part of core consensus code, deployed first to testnet and then to mainnet. CCBN is a decentralized approach to thwart secret mining attacks by notarizing blocks to independent blockchains, providing a way to resolve chain splits in favor of honest mining, which will greatly enhance on-chain security. 

ElectrumG 4.0: it’s time to upgrade to the upstream Electrum 4.0 client and the latest ElectrumX Server with improved security, performance, and more features, including: PSBT support, payment server, native Android support. 

Bitcoin Gold Core v21: continuing to follow upstream updates brings in value bugfixes and security improvements, and also introduces new features including schnorr signatures and taproot.

Refreshed Explorer: we’re deploying a new blockchain explorer (Blockbook and / or Bitcore v8) for improved stability, appearance, and usability.

Lightning Network 

LN Client: we’ll deploy a stable BTG version of a mature lightning client to testnet and then mainnet (lnd, c-lightning, and/or eclair.) Even if fees don’t demand an LN infrastructure, a Lightning Network can still deliver greater efficiency on transactions.

ElectrumG Lightning Network Integration: after deploying new Lightning Network clients, we can enable Lighting Network within ElectrumG and connect it the Bitcoin Gold Lightning Network for near-instant transactions. This depends on both ElectrumG 4.0 and the LN Client.

BTCPay Integration of BTG Lightning Network: BTCPay, the best decentralized payment gateway, already supports BTG, so extending BTCPay to support BTG LN is next. This depends on the LN Client.

Phala Network Partners with Bitcoin Gold https://btgofficial.org/phala-network-partners-with-bitcoin-gold/ Sat, 27 Mar 2021 01:00:37 +0000 https://btgofficial.org/?p=41127

Phala Network Partners with Bitcoin Gold to develop Lightweight Cross-Chain Bridges to the Polkadot Ecosystem for BTG and other Bitcoin-Based Chains

Bitcoin Gold (BTG) and Phala Network are happy to announce a project partnership to develop lightweight, low-cost, trustless bridges by leveraging Phala’s TEE-based confidential computing technology. BTG will be the first asset bridged, but the project is being built to work with tokens from any blockchain based on bitcoin’s underlying technology, including LTC, BCH, DOGE, BSV, and other long-tail offshoots of Bitcoin. This will provide a path for the liquidity of the $36 billion market value of this coin family into the Polkadot ecosystem for use in smart contracts, DeFi, DEXes, and more.

The joint Phala/BTG team’s confidence in this approach rests on three pillars:

  • open-source bridges like Interlay’s PolkaBTC have been demonstrated, but require deep-pocketed backers for security collateral

  • Phala Network has demonstrated the ability to deliver security and confidentiality through a network of TEEs

  • Hang Yin, a co-founder of Phala Network, is also the Lead Developer (and a co-founder) of Bitcoin Gold, bringing deep knowledge of bitcoin-based blockchain tech to the joint project’s leadership

BTG and Phala look forward to collaborating and to helping bring this exciting new technology to BTG investors and hodlers as well as extending this open source technology to other coin projects.

About Bitcoin Gold (BTG)

BTG is a cryptocurrency with Bitcoin fundamentals, mined on common GPUs instead of specialty ASICs. BTG enhances and extends the crypto space with a blockchain closely compatible with Bitcoin (with SegWit and Lightning Network) but without using resources like Bitcoin hash power or vying for the “real Bitcoin” title.

Bitcoin Gold is an open-source project by the community for the community. Our code is freely available on Github, where you can follow or contribute to development. Many coin-related services also provide API support and plugins for developers to use.

About Phala Network

Phala Network tackles the issue of trust in the computation cloud.

This blockchain is a trustless computation platform which enables massive cloud processing without sacrificing data confidentiality. Built around TEE-based privacy technology already embedded into modern processors, Phala Network’s distributed computing cloud is versatile and confidential. By separating the consensus mechanism from computation, Phala ensures processing power is highly scalable. Combined, this creates the infrastructure for a powerful, secure, and scalable trustless computing cloud.

As a member parachain of the Polkadot cross-chain ecosystem, Phala will be able to provide computing power to other blockchain applications while protecting the data layer, enabling possibilities like privacy-protected DeFi trading positions and transaction history, co-computing DID confidential data, developing light-node cross-chain bridges, and more.

On-chain services currently being developed on Phala Network include Web3 Analytics: high-performance smart contracts from Phala enable highly concurrent mass data analytics with privacy, paving the way for an alternative to Google Analytics that inherently respects individual confidentiality.

Things are Brewing at BTG https://btgofficial.org/things-are-brewing/ Wed, 03 Mar 2021 11:00:21 +0000 https://btgofficial.org/?p=41094

Hi!

We haven’t published in a while. It was a very long crypto winter, but our hibernation has come to an end.

We want you to know that we’ve been more active over the past year than a lot of people think.

For example, some of you know that BTG was used in 51% attacks again in January of 2020… but very few know that attacks continued for many months, and that those subsequent attacks failed because the BTG miners and community defeated them! And few realize that we’ve rolled out new technology that better protects our chain. The BTG project has been through a lot and has come out stronger for it – and we will be getting the details of that story out in the coming weeks.

We’ve also got some truly exciting new development brewing with new partners which we’re itching to share. You can expect to see regular updates published in the coming weeks on various projects that are underway with BTG, as well as recaps about what we’ve been through and accomplished in the many preceding months.

In light of all our new developments, we’re also working on a fully updated roadmap to share in the coming weeks.

We’re really looking forward to sharing all we’ve done and all we’re doing – BTG is building and growing, and we want you to know it!

BTG Core Wallet v0.17.3 https://btgofficial.org/core-wallet-v17-3/ Mon, 03 Aug 2020 20:00:58 +0000 https://btgofficial.org/?p=40893

We’re thrilled to announce BTG Core wallet v0.17.3!

This important release increases the safety of the BTG blockchain against deep-chain reversions by introducing rolling checkpoint finalization.

You can download the latest release here:

Typical users can shut down the app, install the new version, and restart the app without issue, but it’s always best to backup everything, especially wallet.dat files, first. The v0.17.3 release notes are here.

Version v0.17.3 is a direct drop-in replacement for v0.17.1 or v0.17.2, but before upgrading from an older version like v0.15.2, exchanges, services, and anyone who writes code against the API should should check the full release notes for v0.17.1 as some APIs are deprecated and there are changes to way the config file is read.

Notable Changes

Rolling Checkpoint Finalization

A finalized block is one which the system considers non-replaceable. If a node receives a sudden chain of blocks which is a “fork” of the blockchain going back further than the last finalized block, the fork will be rejected. This makes long attack forks impossible.

Every time a new block comes in, the node will check if a previous block is newly eligible to be finalized. To ensure normal chain function and prevent potential problems, blocks aren’t eligible until some time passes (see the release notes for full details.) This acts like a traditional bitcoin checkpoint, but over time the finalized block rolls forward, hence the name. The important part is that deep reorganizations become impossible.

Most transactions – over 60% – will be in a finalized block when they have just 10 confirmations, but under some rare conditions, it may take 20 confirmations or more. (In 99.92% of the past 100,000 blocks, finalization would have happened by the 19th confirmation.)

RPC Changes

The new RPC call getfinalizedblockhash will report the blockhash of the most recent finalized block so that developers can code new behavior around this security information. 

Looking forward as always,
The Bitcoin Gold Organization

BTG Core Wallet v0.17.1 https://btgofficial.org/core-wallet-v17-final/ Mon, 02 Mar 2020 12:00:17 +0000 https://btgofficial.org/?p=40974

We’re thrilled to announce BTG Core wallet v0.17.1!

This major update to our Full Node wallet includes substantial new features for BTG and numerous bug fixes.

You can download the latest release by clicking below:

Typical users can shut down their node, install the new version, and start their upgraded node without issue, but it’s always best to backup everything, especially wallet.dat files, first.

As promised, BTG strives to stay in-sync with Bitcoin Core’s developing features. BTG Core v0.17.1 parallels features of Bitcoin Core v0.17.1; developers and engineers can expect to see the same changes they already experienced upgrading Bitcoin Core from version 15 to versions 16/17.

IMPORTANT: Do not use v0.17.1 for in-place node upgrades in production environments without first testing and modifying! This version makes important changes to some APIs and the conf file (see release notes). Also, if you run a full transaction index (most individuals don’t choose to do this), the txindex db will be migrated, which can take many hours before the node is usable again.

Notable Changes

Compact Blocks

The most immediately important feature: Compact Blocks are fully implemented on BTG for the first time. This enhancement is critical to support Light Wallet protocols like Neutrino, which enable Lightning wallet and mobile wallet apps to work directly with the BTG network without having to download and store the whole blockchain.

Wallet Enhancements

The wallet and user interfaces now fully support Segwit addresses and full native Segwit support is enabled. All new wallets are HD-wallets (hierarchical deterministic – until now, users still had the option of making a new wallet that was not HD.)

PSBT Support

Bitcoin’s PSBT interchange format is introduced for BTG in this version, though it is not yet supported in the GUI. PSBT allows for transaction creation and signing to be coordinated among multiple parties (for hardware wallets, multisig systems, CoinJoin, etc.)

For Developers and Engineers

With this version, the RPC changes and new ‘label’ API you may know from Bitcoin Core versions 16 and 17 are now in place for your BTG nodes. Developers need to be aware that the deprecated ‘getinfo’ API is now retired in favor of more specific calls (see this about the API change) and pool operators need to be aware of the impact to stratum implementation (see this GitHub example for a guide. )

Summing Up

While this new version is not a hard fork and is not a required update (your current nodes will continue to work just fine), it will be a recommended upgrade for all users because of the many improvements. This updated version of the BTG Core Wallet delivers bug fixes, enhances performance, and delivers critical features that enable many new technologies that have been held back until now.

Looking forward as always,
The Bitcoin Gold Organization

Developers and interested parties can see the work on projects like neutrino, lnd, and other projects on the BTG project’s GitHub.

Leadership for Another Year https://btgofficial.org/leadership-for-another-year/ Mon, 19 Nov 2018 19:50:11 +0000 https://btgofficial.org/?p=36381 It has been just over a year since the Bitcoin Gold project launched. Since then, we’ve been striving to carefully shepherd our young project towards being a fair, transparent, and above all, decentralized cryptocurrency. As the Community is aware, leadership for the project is provided by a multi-person Board. That Board, which began with the six co-founders of the project, has consisted of seven members for most of the past year. Today we have some news about changes in the Board.

We want to share with the community that Jack Liao, who first inspired the Bitcoin Gold Project, is stepping down from the Board. His future involvement will be limited to an Advisory capacity. Jack Liao is a colorful individual and a force of personality who brought vision, energy, and an extensive network in the crypto community to the project. He was the first founder of the Bitcoin Gold project and helped build the team of six co-founders.

Jack inspired us and encouraged us to do something ambitious. For that, we will be eternally grateful. At this time, Jack wants to focus his time in other endeavors, encouraging competition and diversity in the crypto space, and his continuing as CEO of his company, LightningASIC. We wish him good luck in all his future endeavors.

We also want to share that fellow member of the Board and Lead Developer, H4x3rotab, has decided to publicly share his identity. While we will all still know him as H4, he is no longer anonymous. Hang Yin studied Computer Science at Fudan University and was, until recently, a Google software engineer. He has given up his role at Google to focus all his time into crypto-related work, especially the BTG project, and will continue to serve as a member of the Board and as Lead Developer.

The other members of the Board remain, which means five of the six members of the Board are also co-founders of the project (listed here.) Our overall team has grown a great deal since our start in 2017, bringing in fresh energy and ideas. We’re excited to see growing attention and new interest from the crypto developer community – we’ll always welcome new contributors. We’re looking forward to sharing the next year of our journey with our growing Community!

Gratefully, most sincerely, and with best wishes,
The Board of the Bitcoin Gold Organization

ElectrumG – Release 3.2.1 https://btgofficial.org/electrumg-release-3-2-1/ Tue, 10 Jul 2018 16:30:31 +0000 https://btgofficial.org/?p=31531

The BTG blockchain has been performing wonderfully since the successful Network Upgrade last week. If you’re using our ElectrumG wallet, make sure you update to the latest version, published last week:

ElectrumG 3.2.1

ElectrumG 3.2.1 is a stable release and is fully compatible with the recently Upgraded Bitcoin Gold Network.

What is ElectrumG?

ElectrumG is our version of the popular Electrum Bitcoin Wallet, modified for BTG. It’s is a full-featured wallet that’s easy to use for beginners but provides many advanced features – including invoices, multisig wallets, cold storage, and a rich set of functionality for advanced users and developers.

Most importantly, ElectrumG is very quick to load and very lightweight, consuming a lot less disk space than a full node wallet.

How’s it so Lightweight?

Unlike a “full node” wallet, ElectrumG on your computer doesn’t validate every BTG transaction and maintain a full copy of the BTG blockchain, so it doesn’t need hundreds of gigabytes of space on your computer. Instead, it relies on lightweight block headers and uses SPV (Simplified Payment Verification, as described in the Bitcoin Whitepaper) to verify payments. Like any SPV wallet, ElectrumG relies on ElectrumX servers for some functions, such as receiving new block headers, or broadcasting new payments after they are signed – but the private keys used to sign those transactions never leave your computer. You remain in complete control of your private keys.

Production vs Beta

The current production version, ElectrumG 3.2.1, was released just before the Network Upgrade hardfork. The wallet and back-end ElectrumX servers were upgraded to remain functional after the fork. This version does not include support for hardware wallets, which will be added in an upcoming Beta. (Hardware wallet support was initially planned for the 3.2.1 release, but needed to be delayed in favor of rolling out support for the Network Upgrade.)

Free and Open Source!

ElectrumG will continue to be free and open-source, with ongoing development and support provided by the Bitcoin Gold Organization. (See the full source code on GitHub.)

The Bitcoin Gold Organization also hosts and maintains a globally distributed set of ElectrumX servers, which were upgraded for the Network Upgrade.

We’d like to thank Spesmilo (Electrum) and Kyuupichan (ElectrumX) for their hard work on the Electrum projects over the years, as well everyone else in the Open Source Community that has contributed to the creation and growth of projects like these.

We’ll continue to work hard to provide the kind of software users want, the services developers need, and to continue expanding and supporting the Bitcoin Gold Ecosystem.

Working hard and making progress,
The Bitcoin Gold Organization
#1CPU1VOTE


Where do I get it?

ElectrumG 3.2.1

Please report Issues on GitHub or the Forum.

Feature List

Beyond a pleasant interface, ElectrumG provides users with a full suite of functions:

  • seed recovery phrases, a secure system which is more user-friendly than hexadecimal codes
  • wallet encryption
  • multi-signature wallets, for cases where control of funds needs to be distributed
  • easy import of Bitcoin address or private keys
  • cold storage – the ability to create and sign raw transactions offline and then broadcast
  • invoicing functionality

In the near future, ElectrumG will also include:

  • hardware wallet connectivity, so you can use ElectrumG while keeping your private keys on a hardware wallet like Trezor, Ledger, or KeepKey

For developers, ElectrumG provides:

  • a powerful command line interface
  • ability to use cold storage with the command line
  • a GUI Python console
  • an ElectrumG daemon for scripted uses, such the ability to accept BTG on a website with signed payment requests

A Successful Network Upgrade https://btgofficial.org/a-successful-network-upgrade/ Sun, 08 Jul 2018 03:32:14 +0000 https://btgofficial.org/?p=30951 Block 536200 was mined Jul 3, 2018 at 9:59:26 PM UTC

Unlocked: New PoW, Equihash-BTG
Unlocked: New DAA, LWMA

The Network Upgrade was a success, the blockchain is stable, and all partners can resume regular activities – including returning confirmation requirements to pre-fork levels.

Now delivering: greater safety, greater stability, and renewed ASIC resistance

It has been a long, hard couple of weeks, but we made it!

For anyone who doesn’t yet know:

Equihash-BTG, our new Proof of Work algorithm, can’t be mined by current ASIC miners, but can be mined by GPUs. So, this kicks them out of our pools.

The new algorithm also comes with personalization that makes it harder to re-direct mining power through a “hashrate market.” The recent “51%” attacks, which may or may not have involved ASIC miners, were channeled through hashpower rental markets – but with this change in PoW, there’s no longer a rental market for the algorithm we’re using, and it’s harder to set one up than before. This means more safety.

Meanwhile, LWMA, our improved Difficulty Adjustment Algorithm, makes our blockchain more responsive to shifts in hashpower so that the block time is more stable. The GPU hashpower market has become more liquid than it used to be, with more miners adopting “auto-switching” in pursuit of profit instead of supporting specific coin projects. As a result, hashpower can move quickly after a price move in one of several coins, leading to unstable block times. With our improved algorithm, the blockchain adjusts more quickly, providing a steadier flow of blocks.

Both improvements are up and running as expected.

A few technical notes about the new PoW algorithm, Equihash-BTG, are in order. It consumes vastly more memory than traditional Equihash, so ASICs are no longer able to mine, but GPUs with 3GB VRAM or more can keep working. It’s also important to understand that the new algorithm is about 15 times harder, so each miner produces about 1/15th as much hashrate as they did before. This means that our pre-fork network hashrate of 25 to 30 MSol should be expected to decrease to between 1.6 and 2.0 MSol – which is precisely the range where we stabilized after the hardfork! We’re delighted to see we’ve had no net loss of miners due to the PoW change!

The new Difficulty Adjustment Algorithm also appears to be performing just as well as we hoped. At the time of the Upgrade, the Difficulty was intentionally dropped* down sharply, so the initial 45 blocks after the hardfork came rapidly – just under 2.5 minutes per block. Then the new DAA kicked in (when the required 45-block averaging window filled up) and began adjusting the Difficulty upwards based on the block time, bringing the average block time up to the 10-minute target within a day.

Safety and stability. Two great improvements that everyone can appreciate!

In the three days since then, the block rate has been much more consistent than it was before, both because of our escape from the volatile hashpower rental market, and because of a better-balanced and more responsive DAA. On top of that, the removal of the rental market means the removal of a major attack vector, resulting in massive improvements in safety and stability. That’s two great improvements that everyone can appreciate!

A Bit of Thanks

We’re grateful to our diverse pool of miners – and our network of mining pools – for working hard to get through this critical period. Now that the blockchain is stable, it’s safe for all our partners, including exchanges, to resume regular activity. Everything is back to normal, so it’s time to get back to work – including reopening wallet systems and returning confirmation requirements to pre-fork levels.

Everything is back to normal, so it’s time to get back to work.

We appreciate the hard work and confidence shown by all our partners – miners, pools, exchanges, wallets, explorers, merchant services – this upgrade kept everyone busy before and after the fork, and we thank them all for their diligence. Any partner experiencing any difficulties is more than welcome to reach out to the team for assistance.

Up Next – Great Things!

We know that this a milestone, not an endpoint. It’s just a waypoint we pass on the way to better things. And though a lot of us have been focused on this hardfork, others have continued working other projects – so we have many great things to share with the Community in the coming days and weeks!

Looking forward with excitement,
The Bitcoin Gold Organization

*The Difficulty was dropped to compensate both for the harder Equihash-BTG mining, and to compensate for an inevitable temporary reduction in miners at the time of the transition due to miners needing to shut down, make changes, and start up again.
