What Bitcoin II offers

  • SHA-256 Proof-of-Work: Same hashing algorithm and security assumptions as Bitcoin Core.
  • Fixed 21,000,000 BC2 supply: Mining subsidy halves every 210,000 blocks, echoing Bitcoin-II.org guidance.
  • Difficulty retargeting: Adjusts every 2,016 blocks so block times stay close to ten minutes.
  • Integrated DNS seeding: Core releases ship with community DNS seeds so fresh installs discover peers automatically.
  • Fresh genesis block: A brand new chain so miners, holders, and builders start on equal footing.

Network fundamentals

Core parameters published on the official Bitcoin II launch site.

  • Consensus Proof-of-Work secured by the SHA-256 hashing algorithm.
  • Max supply 21,000,000 BC2 with the same halving cadence of every 210,000 blocks.
  • Difficulty retarget Adjusts every 2,016 blocks so block times remain consistent as hashrate changes.
  • Fresh genesis Bitcoin II starts from a brand new blockchain, giving miners an even playing field.
  • Mining cadence Launch difficulty reset to 1 for fairness, while today's security relies on SHA-256 ASIC hash power.

Looking to mine? Pair SHA-256 ASIC hardware with the pool list on MiningPoolStats and confirm wallet compatibility via the official releases below.

Keeping blocks lean

Bitcoin II Core retains the 80-byte OP_RETURN ceiling so transaction data stays prioritized over arbitrary payloads.

Future consensus work is focused on reducing non-transactional storage vectors altogether—follow progress in the Daily Network Report.
