What is BitcoinII (BC2)?

BitcoinII (BC2) is a proof-of-work cryptocurrency built as a direct continuation of Satoshi Nakamoto's original vision and implementation of a peer-to-peer electronic cash system. Rather than reinventing blockchain technology, BitcoinII positions itself as the sister chain to Bitcoin, constructed on Satoshi's original principles. The project describes itself simply as "Bitcoin, re-launched."

At its core, BitcoinII is derived from the Bitcoin Core 0.27.0 code base, making it a faithful recreation of the original Bitcoin implementation. The network utilizes a Proof of Work consensus mechanism with the SHA-256 hash algorithm, ensuring robust security and reliability for its users. The supply cap is hard-coded at 21 million BC2, with coins mined out over approximately 100 years via block rewards that started at 50 BC2 per block. There was no premine, and the asset remains fully mineable by anyone with appropriate hardware.

Who created BitcoinII?

The BitcoinII project is maintained by the BitcoinII Organization on GitHub, which hosts repositories including "BitcoinII Core Development" and "Implementation of the BitcoinII Blockchain." The GitHub release author and maintainer handle is KvantaMechanic, who is responsible for publishing BitcoinII Core releases. The origin of the project traces back to a BitcoinTalk thread posted on July 2, 2025, titled "I kinda screwed up…" in which the creator describes taking the Bitcoin Core 0.27.0 code base and building what was named "BitcoinII," or BC2, as a faithful recreation of the original Bitcoin implementation. Detailed public information about the broader team is currently limited.

How does BitcoinII work?

BitcoinII operates on a Bitcoin Core-derived blockchain that uses Proof of Work consensus with the SHA-256 hashing algorithm. Miners compete to solve cryptographic puzzles to add new blocks to the chain, securing the network and processing transactions. The core technology behind BitcoinII is anchored in this Proof of Work algorithm, which ensures robust security and reliability for its users.

The network has evolved through several notable releases. BitcoinII Core v29.1.0, released by KvantaMechanic on November 27, was a mandatory release including an updated seed server and blockchain checkpoints, with previous v29 releases fully deprecated. The latest release, BitcoinII v31.1.0, was published by KvantaMechanic on August 29 and introduced consensus-level changes including ShockWave per-block difficulty adjustment, consensus-level Ordinals, inscriptions, and Runes mitigation, BC2 transaction replay protection, fork-aware header synchronization, and associated wallet, mining, mempool, RPC, validation, and PSBT updates. These upgrades demonstrate ongoing development to address network challenges and improve functionality.

What makes BitcoinII unique and valuable?

BitcoinII distinguishes itself through its commitment to preserving Satoshi Nakamoto's original vision rather than pursuing novel or experimental approaches. It is characterized as "The Sister Chain to Bitcoin Built on Satoshi's Original Principles," emphasizing continuity over reinvention. The project's origin statement reflects a deliberate effort to recreate the original Bitcoin implementation faithfully using the Bitcoin Core 0.27.0 code base.

From a technical standpoint, BitcoinII has implemented several distinctive features. The ShockWave per-block difficulty adjustment aims to provide more responsive mining difficulty. The consensus-level Ordinals, inscriptions, and Runes mitigation reflects a deliberate policy to limit certain types of on-chain activity that have become prominent on other Bitcoin-derived networks. BC2 transaction replay protection and fork-aware header synchronization further enhance network security and interoperability. The absence of a premine and the fully mineable nature of the asset align with the project's stated principles of fairness and decentralization.

What is BitcoinII used for?

BitcoinII functions primarily as a peer-to-peer electronic cash system, following the original Bitcoin model. BC2 coins are used to transfer value across the network, pay transaction fees, and reward miners for securing the blockchain. As a mineable proof-of-work cryptocurrency with a fixed supply cap, BitcoinII serves as a store of value and medium of exchange within its ecosystem.

The asset is traded on various markets, including BC2/USDT and BC2/BTC pairs, and can be converted to fiat currencies such as AUD, BRL, CAD, EUR, GBP, HKD, RUB, SGD, TWD, and KRW. Trading markets have included NestEx, CoinEx, and NonKYC Exchange. The project also supports solo mining, allowing individual participants to mine BC2 directly. Additionally, BC2 may be available for swapping via decentralized products, and community resources such as wallet setup guides and solo mining tutorials are available to help users participate in the network.

How Is the BitcoinII ecosystem developing?

The BitcoinII ecosystem is actively developing, with the BitcoinII Organization maintaining eight repositories on GitHub. The canonical source code repository, BitcoinII-Core, serves as the reference implementation of the BitcoinII blockchain. Release activity has been consistent, with v29.1.0 and v31.1.0 representing significant milestones in the project's technical evolution.

Community resources include official and additional blockchain explorers, price tracking pages across multiple platforms, and educational content such as wallet setup and solo mining guides. The project maintains an official website and whitepaper, and discussions occur on platforms including BitcoinTalk and Reddit. The ecosystem also includes trading markets on various exchanges and conversion pairs for major fiat currencies. As the network continues to mature, ongoing development focuses on consensus improvements, security enhancements, and expanding accessibility for users and miners.

How to mine BitcoinII?

BitcoinII uses a Proof of Work consensus mechanism with the SHA-256 hash algorithm, making it mineable with hardware compatible with SHA-256 mining. The network started with block rewards of 50 BC2 per block, with the emission schedule designed to distribute the full 21 million BC2 supply over approximately 100 years. There was no premine, meaning all coins enter circulation through mining.

Miners can participate in BitcoinII through various approaches, including solo mining, which allows individual participants to mine BC2 directly without joining a pool. The project has released consensus-level changes such as ShockWave per-block difficulty adjustment, which affects mining dynamics. Community resources, including a solo mining guide titled "How To: Solo Mine for Bitcoin II (BC2)," are available to help new miners get started. As with any proof-of-work cryptocurrency, mining profitability depends on factors such as hardware efficiency, electricity costs, network difficulty, and BC2 market price.

How to keep your BitcoinII Coin safe?

Securing BitcoinII coins requires adherence to established cryptocurrency security practices. Users should store their BC2 in wallets that provide control over private keys, ensuring that only they have access to their funds. A wallet setup guide titled "How To Get A BitcoinII (BC2) Wallet Setup" is available to assist users in creating and configuring their wallets properly.

Best practices for keeping BC2 safe include using hardware wallets for significant holdings, keeping private keys and seed phrases offline and confidential, and verifying wallet addresses before sending transactions. Users should also be cautious of phishing attempts and only download wallet software from official sources. Given that BitcoinII Core v31.1.0 includes BC2 transaction replay protection and fork-aware header synchronization, keeping wallet software updated to the latest release is important for security and compatibility. As with all cryptocurrencies, diversifying storage methods and maintaining backups can help mitigate risks associated with loss or theft.
