Làm thế nào để mua Bitcoin Cash II (BCH2)

Bitcoin Cash II (BCH2) is a SHA-256 proof-of-work cryptocurrency created through a hard fork of BC2 (BitcoinII) at block height 53,200. BCH2 inherits BC2's complete transaction history through the fork block while adopting Bitcoin Cash consensus rules, including 32MB blocks, the ASERT difficulty adjustment algorithm, Schnorr signatures, native introspection opcodes, and protocol upgrades through Upgrade 11 (ABLA). At the time of the fork, all BC2 holders received BCH2 at a 1:1 ratio, with approximately 2,660,000 coins distributed. BCH2 had no premine, no developer allocation, and no ICO. All new coins enter circulation exclusively through mining, following Bitcoin's original halving schedule with a maximum supply of 21,000,000 and a current block reward of 50 BCH2. BCH2 launched with a 1-hour ASERT half-life designed for difficulty stability on a new network. At block 92,736, the half-life automatically transitions to 2 days, matching Bitcoin Cash Node (BCHN). This transition is built into the consensus rules and requires no hard fork. SIGHASH_FORKID provides replay protection, ensuring BCH2 and BC2 transactions are independent. The project also implements DSProof for real-time double-spend detection on unconfirmed transactions, and a witness-via-scriptSig mechanism that allows existing SegWit UTXOs from BC2's history to be spent on the BCH2 chain. The codebase is built on BitcoinII Core v27.1 and is open source under the MIT license.
