What is BTX?

BTX is a peer-to-peer computational settlement system combining matrix-multiplication proof-of-work, post-quantum spend policies, shielded settlement with selective disclosure, and a layered architecture designed for institutions, exchanges, bridges, and autonomous agents.

The protocol is built on Bitcoin Knots v29.2 and diverges from upstream Bitcoin in several fundamental ways:

MatMul Proof-of-Work — block production requires 512×512 matrix multiplication over the finite field F(2^31 − 1), binding each proof to present chain state
Post-Quantum Cryptography — ML-DSA-44 (FIPS 204) and SLH-DSA-128s (FIPS 205) spend paths from genesis
Shielded Settlement — SMILE v2 was introduced at block 0; current production support is limited to shielded-to-transparent exits and recovery after the 125000/128000 shield-ingress sunsets
90-second blocks with per-block ASERT difficulty adjustment
21M fixed supply, 20 BTX initial subsidy, 525,000-block halving interval

Quick Start

Build the node from source:

git clone https://github.com/btxchain/btx
cd btx
cmake -B build-btx
cmake --build build-btx -j$(nproc)

Start the mainnet node:

./build-btx/bin/btxd -mainnet -rpcport=19334

Check network status:

./build-btx/bin/btx-cli -rpcport=19334 getmininginfo

Architecture

BTX follows a narrow base layer philosophy. The base layer orders settlement instructions, enforces spend conditions, maintains transparent and shielded state, and publishes a public work benchmark. Higher-layer systems — bank ledgers, exchanges, bridge operators, agent coordination services — settle against that base without sharing a global runtime.

The rules of settlement are identical for every participant. Any participant satisfying the spend conditions can settle. Any participant not satisfying them cannot.
