Python SDK

The Python SDK provides payload hash verification and on-chain anchor checks. Signature verification is planned.

Example​

from olymp_verifier import verify_payload_hash, verify_anchor

ok = verify_payload_hash(payload_bytes, expected_hash_hex)

expected = {
  "provider": "0x70997970C51812dc3A010C7d01b50e0d17dc79C8",
  "sourceProvider": "0x70997970C51812dc3A010C7d01b50e0d17dc79C8",
  "schemaId": "0xa52094c663b57018c5cdc2084026c4b5bc16c72d9e040aed163e68750dc3cf70",
  "dataTypeHash": "0xc72a5198e7e10c034ec16ab75c9ee049cdf0f712e06398fa02bf301dcc74cd92",
  "windowStart": 1700000000,
  "windowEnd": 1700000600,
  "payloadHash": "0x458519ac7f8531c1b661fef583b421cdec31181f61f951ba95dc9891e41830cb",
}

anchor_ok = verify_anchor(
  "http://localhost:8545",
  "0x000000000000000000000000000000000000aaaa",
  "0x8e466e6bb8feb3522eec2d274eb6dde6bb1cc0218195379934c021ae324f241f",
  expected,
)

Notes​

  • Signature verification is not implemented yet.
  • Use test vectors in test-vectors/ for payload and anchor inputs.

Disclaimers​

Verification outcomes are variable and depend on on-chain state and payload integrity. No guarantees. Not investment advice.
