The talk covers three aspects of a proposed Ethereum domain name system: the technical implementation of the recursive and modular lookup protocol (https://github.com/Arachnid/EIPs/blob/ens/EIPs/erc-draft-ens.md), the auction aspects for domain registration and reselling (https://github.com/ethereum/EIPs/issues/26) and the possible attack vectors along with the suggestion solution and future expansion.
