Bitcoin Cash II (BCH2)A Return to Decentralized Mining Through Fair Distribution
What is BCH2?BCH2 (Bitcoin Cash II) is a SHA-256 proof-of-work cryptocurrency that forks from
BC2 (BitcoinII) at block height 53,200, upgrading to full Bitcoin Cash consensus rules. Every BC2 holder at the fork block receives an equal amount of BCH2 at a 1:1 ratio — no registration, no claims process, no KYC.
No premine. No dev fee. No ICO. 100% of new coins go to miners.
Estimated mainnet launch: March 7–9, 2026
Why BC2?BC2 (BitcoinII) deserves credit as a well-executed Bitcoin implementation. It launched in 2025 with a clean genesis block, fair distribution, and a working network that has produced over 53,000 blocks. BC2 built a real community, got listed on multiple exchanges, and proved itself as a functioning SHA-256 chain. That's not easy to do.
BCH2 builds on that foundation. Rather than starting from scratch, I chose to fork BC2 because it had something rare in this space — a genuinely fair launch with no premine and an active mining community. By combining BC2's honest distribution with Bitcoin Cash's battle-tested protocol upgrades (ASERT DAA, 32MB blocks, Schnorr signatures, native introspection, DSProof, ABLA), BCH2 gets the best of both worlds.
BC2 continues as its own chain. BCH2 is additive — it doesn't take anything from BC2. If you hold BC2, you now hold coins on two chains.
How to Get BCH2Every BC2 coin you hold at block 53,200 = 1 BCH2. Free.If you're interested in BCH2, the simplest path is to
acquire BC2 before the fork. BC2 is currently trading on several exchanges. Any BC2 in your wallet at fork height 53,200 automatically becomes an equal BCH2 balance — you end up with coins on both chains.
This is the same model Bitcoin Cash used in 2017. People who held BTC before the fork received BCH for free. The same opportunity exists now with BC2 → BCH2.
BC2 is available on: CoinEx, NonKYC.io, and other exchanges. Check CoinMarketCap or CoinGecko for current listings.
⚠️ Important: Get Your BC2 Off Exchanges Before the ForkIf your BC2 is sitting on an exchange,
you may not automatically receive your BCH2. Exchanges control the private keys, and it's up to each exchange whether they support the fork and credit BCH2 to customers.
I have notified all exchanges currently holding BC2 about the fork and provided full technical support for integration. However, there is no guarantee every exchange will act on this.
You have two options:Option 1 (Recommended): Withdraw to your own walletMove your BC2 to a wallet where you control the private keys before block 53,200. After the fork, import those same keys into a BCH2 wallet and your BCH2 will be there. This is the safest way to guarantee you receive your BCH2.
Option 2: Ask your exchange to support BCH2Contact your exchange's support team and request they credit BCH2 to customers who held BC2 at the fork block. The more customers who ask, the more likely they are to act. Point them to
https://bch2.org for technical details.
Replay protection (SIGHASH_FORKID) is in place — your BC2 and BCH2 are completely independent. Spending on one chain does not affect the other.

Key FeaturesASERT Difficulty AdjustmentPer-block difficulty targeting from Bitcoin Cash (BCHN v29). Launches with a 1-hour half-life for attack resistance on a new chain, then automatically transitions to the standard 2-day half-life at block 92,736 (~9 months). No hard fork needed — it's baked into consensus from day one.
DSProof (Double-Spend Protection)Real-time detection of double-spend attempts on unconfirmed transactions. When a conflicting transaction is detected, a DSProof message is broadcast network-wide within seconds. This makes zero-confirmation payments significantly safer for merchants.
SegWit UTXO MigrationBC2 has SegWit UTXOs in its chain history. BCH2 implements witness-via-scriptSig so existing P2WPKH, P2WSH, P2TR (key-path), and P2SH-wrapped outputs can all be spent post-fork. Signature data moves from the witness field to scriptSig. Same cryptographic security, full replay protection. No coins left behind.
Note: Taproot script-path spending is not supported — only key-path. If you have complex Taproot scripts on BC2, migrate before the fork.
Full BCH Protocol StackAll Bitcoin Cash upgrades from 2017 through 2025 activate at block 53,201:
- Schnorr signatures
- OP_CHECKDATASIG
- Canonical transaction ordering (CTOR)
- Native introspection opcodes
- 64-bit integers and BigInt
- ABLA (Adaptive Blocksize Limit Algorithm)
- Covenants via introspection
Anti-Gaming ProtectionThe wallet implements balance origin verification to prevent double-claiming across address types (SegWit → Legacy). Fork distribution balances are validated against the BC2 chain state.
MiningBCH2 uses SHA-256. Any Bitcoin or BCH ASIC works.
At launch difficulty, home miners and small operations can realistically find blocks. Lottery miners (Bitaxe, Nerdminer) have meaningful odds.

Claiming Your BCH2[list=1]
- Download BCH2 wallet from https://bch2.org/download
- Import your BC2 private keys (WIF format)
- Your BCH2 balance matches your BC2 balance at block 53,200
The wallet scans all derivation paths automatically — Legacy (BIP44), Native SegWit (BIP84), and Wrapped SegWit (BIP49). If you had BC2 in any address type, the wallet will find it.
