AmericanFortress Unveils Zero-Knowledge Proof for Cross-Chain Wallet Verification
- —ZKPoSP extends seed-provenance proofs from a single derived address to relationships between addresses on different curves, including secp256k1 and Ed25519
- —Generating one derivation proof takes about 6.65 seconds and verification 475 ms, with proof sizes near 9.7 MB
- —A two-chain transfer is estimated at 13.3 seconds to prove and 950 ms to verify, but multi-value proofs were not separately benchmarked
- —A second use case, SafeSend, lets a recipient prove payment provenance to an auditor without exposing the viewing key
Why it matters: The scheme targets address substitution against a real deposit, one specific bridge failure mode, but remains a design example with no live integrations.
