RNS Specs - Registry

The registry contract provides a simple mapping between a domain and its resolver. Everything related to domain ownership is managed in this contract, including ownership transfer and sub-domain creation. Each registry entry refers to a resolver which handles the resolution between the name domain and the desired resource.

The RNS Registry contract exposes functions for accessing data and functions to modify data:

Access

  • Ownership

    function owner(bytes32 node) constant returns (address);

    Returns the owner (registrar) of the specified node.

  • Resolution

    function resolver(bytes32 node) constant returns (address);

    Returns the resolver for the specified node.

  • Caching

    function ttl(bytes32 node) constant returns (uint64);

    Returns the time-to-live (TTL) of the node; that is, the maximum duration for which a node's information may be cached.

Modify

  • Ownership

    function setOwner(bytes32 node, address owner);

    Transfers ownership of a node to another registrar. This function may only be called by the current owner of node. A successful call to this function logs the event Transfer(bytes32 indexed, address).

    function setSubnodeOwner(bytes32 node, bytes32 label, address owner);

    Creates a new node label.node and sets its owner to owner, or updates the node with a new owner if it already exists. This function may only be called by the current owner of node. A successful call to this function logs the event NewOwner(bytes32 indexed, bytes32 indexed, address).

  • Resolution

    function setResolver(bytes32 node, address resolver);

    Sets the Resolver address for node, the contract that handles the desired resolutions. This function may only be called by the owner of node. A successful call to this function logs the event NewResolver(bytes32 indexed, address).

  • Caching

    function setTTL(bytes32 node, uint64 ttl);

    Sets the TTL for a node. A node's TTL applies to the 'owner' and 'resolver' records in the Registry, as well as to any information returned by the associated resolver.
