BC2 - A Second Chance

BitcoinII (BC2) is a clean relaunch of the Bitcoin protocol, forked directly from Bitcoin Core version 29.0.0, with modifications to enforce Satoshi Nakamoto's original vision of a peer-to-peer electronic cash system optimized only for payments. Unlike Bitcoin's evolution toward data storage (e.g., Ordinals and inscriptions), BC2 includes policy changes to limit non-monetary data, ensuring lighter nodes and faster transaction relay. It operates as a "sister chain" to Bitcoin, sharing core technology but running on a separate network with its own Genesis block. This setup allows BC2 to coexist on the same hardware as Bitcoin Core without interference. The project emphasizes near 1:1 parity with Bitcoin's capabilities, including security features, while introducing a fair-launch model: no airdrop of pre-existing BTC balances, a reset difficulty to 1, and a brand-new blockchain starting from block #0. As of September 2025, BC2 has a circulating supply of approximately 1.96 million BC2 (about 9% of max supply). Specifications: -Consensus Mechanism: Proof-of-Work (PoW) -Hashing Algorithm: SHA-256 (compatible with Bitcoin ASICs for easy miner onboarding) -Block Time: 600 seconds (10 minutes, identical to Bitcoin) -Block Size: 1 MB (base limit, with potential for SegWit-enabled effective sizes up to ~4 MB, inherited from Bitcoin Core v29) -Total Supply: 21,000,000 BC2 (fixed, like Bitcoin, halvings every 210,000 blocks) -Circulating Supply (as of Sep 2025),: ~1,964,400 BC2 -Difficulty Adjustment: Retargets every 2,016 blocks (2 weeks); launched at difficulty 1 for fair early mining -Genesis Block: Brand new (block #0), not a copy of Bitcoin's chain; timestamp aligned to launch date -Network Ports: Mainnet: RPC 18332, P2P 18333 (Bitcoin testnet-like to avoid conflicts) -Transaction Fees: Dynamic, based on mempool policies from Bitcoin Core v29 (e.g., Replace-By-Fee support, dust limits) -Scripting Language: Bitcoin Script (supports P2PKH, P2SH, SegWit; no major extensions beyond v29) -SegWit Enabled (version 0 witness program for efficiency and malleability fixes) #bc2 #bitcoinii
