RLN Smart Contract

Functionality §

1. RLN rate limit can be defined in terms of multiple messages per epoch.
2. RLN rate limit is set at membership insertion
3. RLN proof generation and validation only requires Web3 RPC calls, no blockchain events or initialisation are needed.
4. An ERC-20 token deposit is needed to insert a membership

Usability §

1. Application developers can set RLN rate limit at insertion.
2. User does not need to wait for merkle tree synchronization and building to start relaying or sending messages.
3. Application does not need to do a Web3 RPC call for every tree change to generate or validate messages.
4. Application can transfer tokens and register membership with a single transaction.
