ICP-03INFRASTRUCTURE & DATA

PROOF-BACKED INFRASTRUCTURE

Bind your off-chain responses to on-chain cryptographic anchors. Every API response verifiable against the SuperRoot.

HOW IT WORKS

Three steps. We do the hard one.

Physical / Cloud Signal

Your infrastructure generates data — sensor readings, compute proofs, oracle updates, RPC responses.

Taifoon Indexing

Bloom filter per block, MMR anchor, SuperRoot binding. Your data is now part of the universal verification tree.

Proof-Backed Response

Every response your API returns includes an MMR inclusion proof. Consumers verify without trusting your servers.
