systems / cross-chain verification
Paxiom
A working prototype for answering historical Ethereum-state questions with Merkle-verified evidence rather than trusting whoever ran the node.
Working substrate
Archived Ethereum account/storage proofs are checked against block-header stateRoot values using Merkle-Patricia verification.
Service layer
Node HTTP services wrap returned artifacts in signed envelopes using canonical JSON before hashing. x402 payment handling, deployment guards, and proof archives are separated into shared machinery.
Audit
The repository includes a deliberately unflattering audit. Fixed findings and still-open findings are kept distinct so testnet deployment or a signed response cannot be mistaken for a production guarantee.
Not built
Recursive zero-knowledge proofs over Ethereum consensus history are design intent, not an implemented feature. Some contracts remain untested and have known findings; a HyperBEAM device path is still a stub.
