Modern Bitcoin Core v31. RandomX runs on ordinary processors — laptop, desktop, home server — not industrial mining hardware.

A second chance at Bitcoin-style home mining: open your wallet, point your CPU at the network, and earn blocks. Same battle-tested Bitcoin Core engine — but RandomX keeps ASIC warehouses and GPU farms out, so miners are people with normal PCs, not datacenters.

Block Zero is an independent layer-1 blockchain built on the Bitcoin Core v31 codebase. It keeps everything that makes Bitcoin solid — the UTXO model, script, SegWit, Taproot, the wallet, the P2P network — and changes exactly one thing that matters for fairness: how blocks are mined.
Instead of SHA-256 (which today only specialized ASIC machines can mine profitably), Block Zero uses RandomX proof-of-work — the same CPU-optimized algorithm used by Monero. RandomX is built to run fast on a normal computer's CPU and badly on ASICs and GPUs. The result:
- Your everyday PC is competitive again. No mining rig, no datacenter.
- No head start for anyone. The chain was launched and mined openly from block 1 — no premine, no presale, no team allocation.
- Home mining again. Download the node, start mining, earn blocks — when a normal computer was enough, before hashrate belonged to warehouses.
This is not Bitcoin and not a token on someone else's chain. It is a fresh chain with its own genesis block, its own rules, and its own coin: BLOZ.
| SHA-256 (Bitcoin today) | RandomX (Block Zero) | |
|---|---|---|
| Best hardware | Purpose-built ASIC machines | A normal CPU |
| Who can mine | Industrial farms | Anyone with a computer |
| ASIC advantage | Enormous | Practically none — RandomX needs a CPU's large cache, fast memory and general-purpose instructions, which ASICs can't cheaply replicate |
| GPU advantage | High | Low — RandomX is memory-hard and branch-heavy, hostile to GPUs |
RandomX continuously executes randomized programs that depend on a multi-megabyte dataset in fast memory. A general-purpose CPU does this naturally; building an ASIC for it would essentially mean building a CPU. That is the whole point — mining stays in the hands of ordinary people.

| Proof-of-work | RandomX (CPU-friendly, ASIC/GPU-resistant) |
| Block time | 10 minutes (target) |
| Difficulty retarget | every 72 blocks (~12 hours) — adapts quickly to hashrate |
| Initial block reward | 50 BLOZ |
| Halving | every 210,000 blocks (~4 years) |
| Maximum supply | 21,000,000 BLOZ |
| Coinbase maturity | 100 blocks |
| Smallest unit | 1 BLOZ = 100,000,000 base units (8 decimals) |
| Ticker | BLOZ (mainnet) · TBLOZ (testnet) |

| RPC port | 8211 (mainnet) · 18211 (testnet) |
Block Zero mirrors Bitcoin's disciplined, predictable issuance: a fixed 21,000,000 BLOZ cap, reached through halvings. Every 210,000 blocks the block reward halves (50 → 25 → 12.5 → …), so the supply curve and scarcity behave exactly like Bitcoin's — only the mining hardware is different.
