17. ENS Architecture

18. Contract MyResolver { address me; function MyResolver() { me =

    msg.sender; } function addr(bytes32 node) constant returns (address) { return me; } } ENS by example: Resolvers

19. Resolving a name

20. Looking up names const address = await ens.resolver(‘arachnid.eth’).addr();

21. Reverse resolution const addr = ‘0x112234455...’ const name = await

    ens.reverse(‘0x112234455...’).name() //for security const forward = await ens.resolver(name) if(addr === forward){ …. }

22. Setting up reverse resolution reverseRegistrar.setName(‘jefflau.eth’)

23. Putting them altogether
