Seraph ID Smart Contract Templates.

Overview

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!

Smart Contract Interface

Issuer

string Name();
string DID();
string PublicKey(); // The public key used to sign claims
Result GetSchemaDetails(string schemaName); // Returns all attributes attached to a schema
Result RegisterSchema(string schemaName, bool revokable, params string[] attributes); // Registers a new schema and defines revokability
Result InjectClaim(string claimID); // Injects a claim to allow for revokability
Result RevokeClaim(string claimID); // Revokes a claim
Result IsValidClaim(string claimID); // Returns a claims revocation status

Root Of Trust

string Name();
string DID();
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

Return Types

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

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.

neo-cli

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

Contributing

Compiling

In order to compile the smart contracts into a avm 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
