About FJARCODE
FJARCODE (FJAR) is an open-source Proof-of-Work Layer 1 blockchain launched in 2026. It operates its own peer-to-peer network and native FJAR cryptocurrency, with a focus on mining, node operation, open infrastructure and experimental cryptographic development.
The network currently uses the SHA3-256T Proof-of-Work algorithm and targets approximately one-minute blocks. Difficulty is adjusted using ASERT, while the block reward begins at 50 FJAR and halves every 210,000 blocks. The protocol specifies a maximum supply of 21 million FJAR.
FJARCODE originally launched using SHA-256d mining before completing a network upgrade to SHA3-256T. The change reopened mining to CPU and GPU hardware rather than relying on SHA-256 ASIC equipment.
The protocol also includes a Code Quantum address and runtime pathway supporting ML-DSA-65, a post-quantum digital-signature algorithm aligned with NIST FIPS 204. Current software exposes both conventional CashAddr addresses and dedicated quantum-address functionality.
The FJARCODE ecosystem includes its own Core wallet, web wallet, block explorers, mining infrastructure, network statistics and public node services. Development and protocol specifications are published openly through the project's website and GitHub repository.
