A four-tier cross-chain bridge implemented across ten sub-crates within bleep-interop. No tier requires a permanently privileged operator or a trusted multisig key set — trust is earned by economics, cryptography, consensus, or governance, depending on the tier.
Latency and security basis trade off deliberately by tier — a user or protocol chooses the tier that matches its risk tolerance and time budget.
Executor auction + escrow. Security: economic — 30% bond slashed on timeout. Protocol fee 10 bps. Auction window 15s, execution timeout 120s.
Live · SepoliaSPHINCS+-bound STARK commitment. Security: cryptographic — PQ-secure, zero trusted operators. Batches up to 32 intents per proof.
Live · SepoliaMulti-client verification across ≥3 independent nodes. Security: 90% consensus threshold across independent implementations.
Mainnet TargetStakeholder governance. Security: full governance consensus — the backstop tier for maximum-value transfers.
Mainnet TargetUp to 32 cross-chain intents batched into a single proof bundle.
Constructs a deterministic transcript from the batch.
The transcript is bound with a post-quantum signature.
A STARK commitment is generated — no SRS, no MPC ceremony.
Verifies using the PQ public key. Double-spend blocked by GlobalNullifierSet with atomic WriteBatch.
Additional chains activate through a governance vote — no unilateral operator can add or remove a route.
