README 快速开始

FreeChess

A decentralized chess site built on Freenet. Play, watch, search and replay games — with no server anywhere in the picture.

Every game, the lobby, the Elo ranking, player presence and the shared history live in Freenet contracts, replicated across peers. The only thing that never leaves your device is your signing key.

What it does

Play chess. Full rules: castling, en passant, promotion, checkmate, stalemate, threefold repetition, the fifty-move rule, and clocks with Fischer increment.
Watch any game live. Every game is public by default. The home page shows the current board of every game in progress, updating in real time.
Search. Find games by player nickname or game id.
Elo ranking. Ratings are verifiable, not self-declared (see below).
Bullet / Blitz / Rapid / Classical, classified by estimated duration.
Presence. See who is online, away or offline.
Challenge someone directly — including a spectator you noticed watching the same game as you.
Shareable replays. Every game gets a link; open it and scrub through the moves. Games export as PGN.
Portable accounts. Export your account as a single string and import it on another device.
Anti-spam. Creating a game costs proof-of-work, and each player has a quota of open games.

How it works

Freenet's core abstraction is a contract: a WebAssembly module that defines both a piece of public state and the rules for merging concurrent updates to it. A contract's key is BLAKE3(BLAKE3(wasm) ‖ params), so the data's identity is bound to the code that governs it — you never have to trust the peer serving it.

FreeChess uses four contracts and one delegate.

Component	Role
`game-contract`	One instance per game: the signed move list, the sealed opponent seat, the result.
`lobby-contract`	A singleton: live games (each with a signed board snapshot), the Elo ranking, and presence.
`archive-contract`	The shared history, sharded into buckets of 1000 games.
`player-contract`	One instance per player: nickname and certified game history.
`chess-delegate`	Runs locally. Holds the private signing key — the one thing not replicated.

One subscription drives the home page

The lobby carries a signed FEN snapshot for every running game, so a clie
