What is BCH2?
Bitcoin Cash II Explained
BCH2 (Bitcoin Cash II) is a SHA-256 proof-of-work cryptocurrency that launched through a fair 1:1 fork of BC2 (BitcoinII) at block 53,200. It runs the full Bitcoin Cash protocol with no premine, no developer fee, and 100% of new coins going to miners.
The Short Version
BCH2 combines two things: the Bitcoin Cash protocol (fast, cheap transactions, 32MB blocks, smart tokens) with the fair distribution model of a genuine no-premine fork. Every BC2 holder at block 53,200 automatically received an equal amount of BCH2 — no registration, no claims process required for most wallet types.
After the fork, all new BCH2 enters circulation exclusively through SHA-256 proof-of-work mining. No developer allocation, no foundation reserve, no inflation beyond the mining schedule.

How BCH2 Differs from Bitcoin Cash (BCH)
BCH2 and Bitcoin Cash (BCH) both implement the Bitcoin Cash protocol but are completely separate blockchains with different histories, communities, and mining ecosystems.
Bitcoin Cash (BCH) forked from Bitcoin (BTC) in 2017 at block 478,558. BCH2 forked from BC2 (BitcoinII) in 2025 at block 53,200. The two chains share the same transaction format and consensus rules but have no shared block history after their respective fork points.
BCH2's primary distinction is its mining accessibility: because BCH2 launched from a relatively young chain (BC2's block 53,200), difficulty started low, making it practical for home ASIC miners, lottery miners, and small mining operations to win blocks — unlike the highly competitive BCH network dominated by industrial mining farms.
Where Does BCH2 Come From?
BCH2's lineage: Bitcoin → BC2 (BitcoinII) → BCH2. BC2 (BitcoinII) was itself a fork of Bitcoin Core. BCH2 forked from BC2 at block 53,200, adopting Bitcoin Cash consensus rules — replacing BC2's original protocol with BCH-compatible rules including ASERT difficulty, 32MB blocks, CashAddr addressing, and Bitcoin Cash script capabilities.
This means BCH2 is not a fork of the main Bitcoin Cash (BCH) chain. It is a new chain built on Bitcoin Cash's technology, launched with fair distribution to BC2 holders.
How to Get BCH2
There are three ways to acquire BCH2:
1. Mine it. Connect any SHA-256 ASIC miner to Forge Pool at stratum+tcp://forge.bch2.org:3333. PPLNS (1% fee) and solo (0.5% fee) modes available.
2. Trade it. BCH2/USDT is listed on NonKYC (no KYC required) and Nestex.
3. Claim it. If you held BC2 at block 53,200 in a self-custody wallet, your BCH2 is waiting. Follow the step-by-step claim guide.
