Code fork
Bitcoin → Brisvia
The official repository explicitly describes this implementation as a Bitcoin Core code fork.
About Brisvia
Brisvia (BRVA) is an open-source Layer 1 cryptocurrency built as a fork of Bitcoin Core v30.2. It retains Bitcoin’s UTXO-based transaction model while replacing SHA-256 mining with RandomX Proof of Work and using ASERT for per-block difficulty adjustment.
The Brisvia mainnet launched on 1 August 2026 at 15:00 UTC. The network began from block 1 with no premine, private sale or spendable genesis reward. Mining is designed around general-purpose CPUs, with RandomX v1.2.2 used as the Proof-of-Work algorithm.
Brisvia targets two-minute blocks and begins with a 50 BRVA block reward. Rewards halve every 1,000,000 blocks, with no tail emission, producing a maximum supply of 100,000,000 BRVA.
The project provides open-source node software, desktop wallet and mining applications, a public block explorer and mining infrastructure. Brisvia also supports SegWit and Taproot from genesis while maintaining a Bitcoin-style transparent blockchain model.
