@baseline-protocol/contracts

Baseline core contracts package.

Installation

npm install @baseline-protocol/contracts

Building

You can build the package locally with make. The build compiles the Baseline solidity contracts package and its dependencies using truffle.

Organization Registry

Each organization registered within the OrgRegistry first generates a secp256k1 keypair and uses the Ethereum public address representation as "primary key" for future resolution. This key SHOULD NOT sign transactions. A best practice is to use an HD wallet to rotate keys, preventing any account from signing more than a single transaction.

Note that an organization may not update its address.

``solidity
struct Org {
address orgAddress;
bytes32 name;
bytes messagingEndpoint;
bytes whisperKey;
bytes zkpPublicKey;
bytes metadata;
}

struct OrgInterfaces {
bytes32 groupName;
address tokenAddress;
address shieldAddress;
address verifierAddress;
}

mapping (address => Org) orgMap;
mapping (uint => OrgInterfaces) orgInterfaceMap;
uint orgInterfaceCount;

Org[] public orgs;
mapping(address => address) managerMap;

event RegisterOrg(
bytes32 _name,
address _address,
bytes _messagingEndpoint,
bytes _whisperKey,
bytes _zkpPublicKey,
bytes _metadata
);

event UpdateOrg(
bytes32 _name,
address _address,
bytes _messagingEndpoint,
bytes _whisperKey,
bytes _zkpPublicKey,
bytes _metadata
);

Shield

Unlike the Radish34 Reference Implementation, the contracts package does not include a "shield" contract. Rather, it is up to each workgroup to determine a suitable shielding mechanism to ensure privacy. For example, the IBaselineRPC implementation within the Nethermind client used in the BRI-1 Reference Implementation ships with shield contract binaries (i.e., including the MerkleTreeSHA contract).
