C++ SDK

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

Example​

ExpectedAnchor expected{
  "0x70997970C51812dc3A010C7d01b50e0d17dc79C8",
  "0x70997970C51812dc3A010C7d01b50e0d17dc79C8",
  "0xa52094c663b57018c5cdc2084026c4b5bc16c72d9e040aed163e68750dc3cf70",
  "0xc72a5198e7e10c034ec16ab75c9ee049cdf0f712e06398fa02bf301dcc74cd92",
  1700000000,
  1700000600,
  "0x458519ac7f8531c1b661fef583b421cdec31181f61f951ba95dc9891e41830cb"
};

bool ok = verify_payload_hash(payloadBytes, expectedHash);
bool anchorOk = verify_anchor(
  "http://localhost:8545",
  "0x000000000000000000000000000000000000aaaa",
  "0x8e466e6bb8feb3522eec2d274eb6dde6bb1cc0218195379934c021ae324f241f",
  expected
);

Notes​

  • Signature verification is not implemented yet.
  • Requires cpr and nlohmann/json for HTTP and JSON.
  • 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.
