Prepunk ENS Quiz | Test Your Knowledge of Historic ENS Domains

Question 1

What makes an ENS name a Prepunk?

Accepted Answer

Its auction was finalized before block 3,919,721, the first transaction on the canonical CryptoPunks contract — a window running from May 9 to June 23, 2017.

Question 2

Exactly how many Prepunks are there?

Accepted Answer

Exactly 79,720. The count comes from immutable 2017 events either side of a single block boundary, so it can never change.

Question 3

Which name holds Prepunk rank #1?

Accepted Answer

rilxxlir.eth, finalized on May 9, 2017 at 11:22:19 UTC — the first HashRegistered event the ENS auction registrar ever emitted.

Question 4

When did the audited ENS auction registrar go live?

Accepted Answer

May 4, 2017 at 11:00 UTC, a timestamp hard-coded into the contract after the March 2017 launch was aborted over two critical bugs.

Question 5

Under Vickrey rules, what did the winner of a 2017 ENS auction pay?

Accepted Answer

The second-highest bid, with a floor of 0.01 ETH. That amount was locked in the winner’s deed contract rather than paid to anyone.
