Software recovered
Original Bitcoin Black V21 code rebuilt and tested on modern Linux.

Preserving the past. Rebuilding the future. An open, evidence-driven effort to recover Bitcoin Black's original ledger and help restore a secure, feeless network.
Original Bitcoin Black V21 code rebuilt and tested on modern Linux.
Two isolated nodes sent, received and reported confirmed test blocks.
Searching for authentic mainnet data, node databases and backups.
Project Phoenix is an independent effort to investigate recovery of the original Bitcoin Black (BCB) blockchain. Our priority is authentic historical data—not inventing a new record of ownership or claiming that balances have already been restored.
We've rebuilt the legacy node software and demonstrated a complete test-network transfer between two nodes. Rebuilding a secure, decentralized public network and validating the original ledger are separate challenges that remain ahead.

Documented technical milestones, not investment claims. Status updated October 2026.
Original V21 node and RPC executables compiled with compatibility fixes.
Test BCB sent and received; both nodes returned confirmed block status.
Seeking a genuine historical ledger, snapshot, or surviving node operator.
Independent auditing, security hardening, infrastructure, and community participation.
Did you operate a Bitcoin Black node between 2019 and 2021? An old full-node database or ledger snapshot could be vital to recovering the historical network.
LMDB data files, RocksDB folders, archived snapshots, explorer datasets, or verified node backups.
Experienced blockchain developers, auditors, and original node operators willing to review evidence.
Help reconnect with original maintainers, representatives, and independent archives.
