Modern BTC code. A second chance at Genesis.
Block Zero is an independent proof-of-work chain — built on Bitcoin Core v31, mined with RandomX on ordinary CPUs, launched with no presale, no premine, and no insider allocation. Fair from block one.
No. Block Zero is not Bitcoin and is not a replacement for it. It is an independent, experimental network inspired by the early Bitcoin era.
No promises of any kind. BLOZ has no guaranteed value, no promised liquidity and no expected return. Participation is voluntary and intended for technical, educational and community purposes.
SHA-256 mining is dominated by ASICs, so normal computers have no realistic chance. RandomX is optimized for general-purpose CPUs and resists ASICs and GPUs, which keeps participation open to ordinary hardware.
No. RandomX is CPU-bound; a GPU gives little to no advantage. A modern multi-core CPU is what matters.
No. There is no premine, no ICO, no founder reward and no hidden allocation. The genesis block carries no spendable allocation; coins are mined by the network after launch. The genesis blocks are reproducible from the public source.
The testnet runs on a RandomX genesis with a Satoshi-style headline. Mainnet is separate and unchanged.
See testnet-reset.md for the reset procedure.

- Proof-of-work: RandomX, with a height-based seed key rotation.
- Target block spacing: 10 minutes.
- Difficulty retargets roughly every 12 hours (72 blocks) for faster response to early hashrate changes.
- Mainnet launched 2026-06-06 06:06:06 UTC; parameters are being observed on the live network.
