# max-chain — a ledger written in MAX

ai infrastructure · max-chain

A permissioned proof-of-authority ledger written in MAX — consensus rules, ledger and contract logic built with the same self-hosting compiler as the rest of the lab's stack.

## The inversion

Most chains are a virtual machine written in one language (Go, Rust, C++) that then interprets contracts written in another. max-chain collapses that seam: the ledger, the consensus rules, and the contract logic are all MAX — the same self-hosting compiler that builds the rest of the lab's stack builds the chain itself.

## What it is

A permissioned proof-of-authority consensus core with its own test suite — a self-contained system, not a public network.

## What is not public

The consensus internals and the authority-management scheme are engineering-open on request; the theorem work behind them stays inside the lab.
