Function: verifyStateSignature()

verifyStateSignature(channel, state, partyId, publicKeyDigest): boolean

Verify a channel state signature using off-chain WOTS verification.

• Rebuilds the canonical Minima update transaction digest and uses
• wotsVerifyDigest to compare it against the party's stored public key digest.

Because the commitment covers the full off-chain state (sequence + balance split + pending HTLCs), any tampering with these fields after signing will cause verification to fail, preserving the integrity of dispute evidence.

Parameters

channel

state

Returns

boolean
