Welcome to Char Network

Bitcoin gives the world a durable settlement layer. Rollups and applications often need a second thing: a way for bonded operators to agree on outcomes before those outcomes settle elsewhere.

Char provides that coordination layer.

What Char Is

Char is a network of operators bonded to Bitcoin. Operators lock BTC, publish signed attestations, and vote on domain outcomes.

When enough active stake endorses the same ballot outcome, Char can produce a DecisionRoll: a proof that consumers can verify independently.

The model is simple:

• BTC bonds create accountability.
• Signed attestations create an auditable operator history.
• Rolls turn stake-weighted agreement into verifiable evidence.

What It Is For

The first focus is validium-style rollups with precommitments.

A rollup can use Char for ordered, stake-backed precommitments while keeping Bitcoin unchanged. The rollup defines a domain, submits vote payloads, and consumes rolls as proofs of the agreed outcome stream.

The same pattern can also support oracles, bridge attestations, and shared ordering systems.

Current Status

The open source prototype includes:

• BTC bonds and stake weighting,
• signed attestation chains,
• merkleized payload commitments,
• decision and impossible rolls,
• RPCs for domains, votes, attestations, and roll lookup.

The next phase is hardening: external verifier libraries, cleaner SDKs, BitVM enforcement paths, and operator tooling.

Why This Exists

Char exists to make Bitcoin-anchored coordination practical without changing Bitcoin consensus.

Services get proofs instead of promises. Operators get accountable roles. Bitcoin remains the settlement layer.
