Block Zero

Missed 2009? Start at Block Zero.

Modern Bitcoin code. CPU-mineable. Fair launch.
Mine with a normal PC — like the early days.

// WHAT IT IS

A fresh chain. The early-Bitcoin feeling, rebuilt.

Block Zero is an independent layer-1 blockchain built on the Bitcoin Core v31 engine. It keeps everything that makes Bitcoin solid — UTXOs, Script, SegWit, Taproot, the wallet, the P2P network — and changes the one thing that decides who gets to mine.

Built on real Bitcoin

Not a fork-and-forget clone. The same battle-tested codebase that secures Bitcoin, running its own genesis and its own rules.

Mine with your CPU

RandomX proof-of-work runs fast on an ordinary processor. No rig, no datacenter — just your computer, like 2009.

Fair from block one

No premine. No presale. No team allocation. Every coin is mined in the open. Nobody got a head start.

// WHY ASICs DON'T STAND A CHANCE

Mining stays human.

Bitcoin today is mined almost only by purpose-built ASIC machines in industrial farms. Block Zero uses RandomX — a proof-of-work designed to run well on a CPU and badly on ASICs and GPUs. Building an ASIC for it would essentially mean building a CPU.

Predictable. Scarce. Bitcoin-grade.

// START MINING

Your CPU. Your blocks.

Mine TBLOZ on the live testnet in a few commands on Windows. Grab the binaries, sync to the public seed, and let your CPU find blocks.

PowerShell
# 1. Get the tools
git clone https://github.com/Rexemre/blockzero-ops.git
cd blockzero-ops\scripts\testnet
.\install-windows.ps1

# 2. Sync to the public seed first (never mine with 0 peers)
.\mine-testnet.ps1 -Status

# 3. Mine
.\mine-testnet.ps1
