BLOCK ZERO

Mine with your CPU — not a warehouse. Start at Block Zero.

RandomX · CPU-only (no ASIC farms, no GPU edge) · Fair launch · Pure proof-of-work · No presale · No insiders · No premine

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.

Why Block Zero (in 30 seconds)

	Block Zero	Typical altcoin
Launch	Fair — mine from genesis	Presale, team allocation, VC
Mining	Your CPU only — RandomX blocks ASICs & GPUs	ASIC farms or GPU pools
Codebase	Modern Bitcoin Core v31	Fork-and-forget spaghetti
Insiders	None	Founders, advisors, VCs

Start in 3 steps

1. Wallet (Windows) — download v1.0.0-rc24 (blockzero-v1.0.0-rc24-windows-x64.zip), unzip, run bin\bitcoin-qt.exe. MSVC runtime is included — no extra install needed.
2. Mine on the official pool — get a bz1… address from the wallet, then:

   git clone https://github.com/Rexemre/blockzero-ops.git
   cd blockzero-ops/scripts/mainnet
   ./mine-pool.sh bz1YOURADDRESS          # Linux / macOS

   Windows: .\install-windows.ps1 then .\mine-mainnet.ps1 -Pool — see blockzero-ops.
3. Stuck or curious? — Join Discord (fastest help). Check your stats at pool.bloz.org with your bz1 address.

You should see New job: … - mining. and hashrate > 0 within a minute. Pool miner: pool-miner-v0.6.9.

What Block Zero is

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.

Why ASICs (and GPU farms) have no chance

	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.

Chain parameters

Property	Value
Consensus engine	Bitcoin Core v31 (UTXO, SegWit, Taproot)
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)
Address prefix (bech32)	bz (mainnet) · tbz (testnet)
P2P port	8210 (mainnet) · 18210 (testnet)
RPC port	8211 (mainnet) · 18211 (testnet)

Emission

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.

Genesis

Start mining (mainnet)

Mine BLOZ on the live mainnet — your CPU, your blocks.

Prebuilt binaries: Releases (node bitcoind, CLI bitcoin-cli, and the GUI wallet bitcoin-qt)

One-click setup (Windows):

git clone https://github.com/Rexemre/blockzero-ops.git
cd blockzero-ops\scripts\mainnet
.\install-windows.ps1
.\mine-mainnet.ps1 -Status   # sync to the public seed first
.\mine-mainnet.ps1 -Pool     # pool mine (recommended)
