C# SDK

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

Example​

var ok = Verifier.VerifyPayloadHash(payloadBytes, expectedHashHex);

var expected = new ExpectedAnchor
{
    Provider = "0x70997970C51812dc3A010C7d01b50e0d17dc79C8",
    SourceProvider = "0x70997970C51812dc3A010C7d01b50e0d17dc79C8",
    SchemaId = "0xa52094c663b57018c5cdc2084026c4b5bc16c72d9e040aed163e68750dc3cf70",
    DataTypeHash = "0xc72a5198e7e10c034ec16ab75c9ee049cdf0f712e06398fa02bf301dcc74cd92",
    WindowStart = 1700000000,
    WindowEnd = 1700000600,
    PayloadHash = "0x458519ac7f8531c1b661fef583b421cdec31181f61f951ba95dc9891e41830cb"
};

var anchorOk = await Verifier.VerifyAnchorAsync(
    "http://localhost:8545",
    "0x000000000000000000000000000000000000aaaa",
    "0x8e466e6bb8feb3522eec2d274eb6dde6bb1cc0218195379934c021ae324f241f",
    expected
);

Notes​

  • Signature verification is not implemented yet.
  • Uses Nethereum for RPC and Keccak.

Disclaimers​

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