7. So what?
8. What is the Internet address of Facebook?
9. Facebook.com 31.13.93.35
10. Overview of this workshop • How does ENS work? • Various ways to have your ENS name • Exercise
11. How does ENS work? = Smart contract
12. Solidity Example : ERC20 (aka programmable money)
13. Solidity Example : ENS
14. “Record” contains address
15. “records” is a collection of Record
16. “setAddr” function records an address for a node
17. “addr” function returns an address for a node
18. • Getting test domain name • Getting subdomain name • Auctioning domain name How do you get your own name?
19. Getting “.test” domain name (Rinkeby/Ropsten) via https://manager.ens.domains
20. Getting subdomain (Mainnet) via https://now.ens.domains
21. Auctioning domain name • Sealed bids over 7 days • Winning bid is locked • Vickrey auction (the winner pays the second-highest price, not the price they themselves bid)
22. • 400k domains registered • E170k ($20M) locked • 1 engineer (when launched) Launched on May 4th 2017
23. • ethfinex.eth = E 201k ($20~40M) • sportsbet.eth = E 188k • consensys.eth = E 184k Highest bid
24. • darkmarket.eth = E20k ($2~4M) • openmarket.eth = E10k • exchange.eth = E6k • ethfinex.eth = E 201k ($20~40M) • sportsbet.eth = E 188k • consensys.eth = E 184k Highest bid Highest won
25. • darmkarket.eth = E20k ($2~4M) • openmarket.eth = E10k • exchange.eth = E6k • ethfinex.eth = E 201k ($20~40M) • sportsbet.eth = E 188k • consensys.eth = E 184k Highest bid Highest won https://www.quora.com/Why-in-a-Vickrey-auction-does-one-pay-the-second-highest-price-and-not-his-price “In a first-price auction, you're trying to guess what everyone else is going to bid and then put down a bid that's slightly higher than the next person's. In a second-price auction, there's no reason for you to do that. You can simply say exactly the maximum price you are willing to pay
26. Exercise
27. • Get domain/subdomain • Set your Ethereum address into ENS name (https://bit.ly/2Igs69z ) • Send eth to your friends! Let’s use ENS
28. What is your ENS name?
