What is BitcoinII?

CategoryDocumentationStatusNeeds ReviewLast reviewed2026-07-01

BitcoinII (BC2) is a peer-to-peer cryptocurrency network. BitcoinII Core is the reference software used to connect to the BitcoinII peer-to-peer network, download and validate blocks and transactions, and optionally provide wallet and graphical user interface functionality.

This page is intentionally factual and narrow. It does not make price claims, investment claims, or roadmap claims.

The public BitcoinII repository README describes BitcoinII Core as software that:

  • Connects to the BitcoinII peer-to-peer network.
  • Downloads blocks and transactions.
  • Fully validates blocks and transactions.
  • Includes wallet functionality.
  • Can optionally build a graphical user interface.

The BitcoinII source headers state that the project was forked from Bitcoin Core version 0.27.0.

The repository README describes BitcoinII as a “Sister Chain” that currently follows Bitcoin development and upgrade paths unless Bitcoin development ceases.
