This repo implements the EIP-6366 and couple examples
This EIP offers an alternative to Access Control Lists (ACLs) for granting authorization and enhancing security. Each permission is represented by a single bit in uint256 from which we can defined up to 256 permissions and 2²⁵⁶ roles. This approach use bitwise operator and bitmask to determine the access right which is much more efficient and flexible than string comparison or keccak(). We are able to specify the importance of permission based on the bit order.
Special roles like Owner, Operator, Manager, Validator are common for many smart contracts because permissioned addresses are used to administer and manage them. It is difficult to audit and maintain these system since these permissions are not managed in a single smart contract.
Since permission and role are reflected by the permission token balance of the relevant account in the given ecosystem, cross-interactivity between many ecosystems will be made simpler.
