A sister chain to Bitcoin. Built on proven SHA-256 technology with a fresh genesis block.
SHA-256 mining algorithm proven since 2009. ASIC-level difficulty ensures network security.
21 million BC2 maximum. Halving every 210,000 blocks (~4 years). Same deflationary model as Bitcoin.
Retargets every 2,016 blocks (~2 weeks) to maintain consistent block times.
BIP34, BIP65, BIP66, CSV, and SegWit all activated. Taproot ready at height 300.
Fresh blockchain, not a fork. Fair start for all participants.
Can run alongside Bitcoin on the same machine. Ports: 8338 (mainnet), 18338 (testnet).
"Many people wish they could have been mining Bitcoin since 2009. Absent a working time machine, this is the best chance at a second chance that we can provide."

Bitcoin-II is positioned as a complement to Bitcoin, not a replacement. Bitcoin (BTC) serves as long-term value storage. BC2 is designed for day-to-day transactions and accessibility.
