Seraph ID Smart Contract Templates.

This repository contains two smart contract templates for the SeraphID Self-Sovereign identity framework:

• Issuer (Dynamic on-chain claim registry)
• RootOfTrust (Enabling hierarchical trust topologies)

Visit the Seraph ID official web page to learn more about self-sovereign identity!

string Name();
string DID();
ECPoint[] GetPublicKeys(); // Get public keys
string GetSchemaDetails(string schemaName); // Returns all attributes attached to a schema
bool RegisterSchema(string schemaName, string schemaDefinition); // Registers a new schema and defines revokability
bool InjectClaim(string claimID); // Injects a claim to allow for revokability
bool RevokeClaim(string claimID); // Revokes a claim
bool IsValidClaim(string claimID); // Returns a claims revocation status
bool AddAdmin(ECPoint pubKey); // Add an admin
bool RemoveAdmin(ECPoint pubKey); // Remove an admin
ECPoint[] GetAdminList(); // Get all the admins

string Name();
Result IsTrusted(string issuerDID, string schemaName); // Checks if a did-schema pair is trusted
Result RegisterIssuer(string issuerDID, string schemaName); // Adds a trusted did-schema pair
Result DeactivateIssuer(string issuerDID, string schemaName); // Removes a did-schema pair

All smart contract calls (except for static information like name, DID, PublicKey) will return a Result object with the following structure:

[
    {"type": "integer", "value": "<SUCCESSSTATUS>"},
    {"type": "<variable>", "value": "<variable>"}
]

If <SUCCESSSTATUS> is 0, an error has occured in the smart contract and the error reason will be listed as the value in the second object. The type of <variable> depends on the function being called.

Deploying the smart contract is a prerequisite to issue claims using the Seraph ID SDK and can be done using neo-cli or neo-gui. Make sure to note down the resulting scripthash as this will be used in the Seraph ID SDK.

Make sure your wallet is open and contains enough GAS to pay for the smart contract creation.

neo> open wallet path\to\mywallet
neo> deploy Path\to\contract\seraph-id-issuer.nef

In order to compile the smart contracts into a nef file, the Neon compiler needs to be available in the PATH of your user.

Note: In order to build the smart contract the neon compiler needs to be run with the --compatibility flag. We recommend either building the compiler from source and changing the compatibility flag to always be on or running the neon compiler from the command line
