Description

Deployed by Hudson Jameson — Ethereum Foundation community manager and long-time organizer of the core-dev calls — on 2016-01-02 06:48:39 UTC at block 908,565, just 89 seconds before his well-known Marriage Registry (0x58641c…) in the same session. It is an empty contract whose only logic is a constructor recording the deployer in storage slot 0; the deployed runtime is the 6-byte empty body 0x606060405200. Compiled with soljson v0.1.5 optimizer ON to match the Marriage Registry deployed moments later. Both runtime and creation bytecode reproduce byte-for-byte.

SolidityExact bytecode match(40 bytes)
Compiler: soljson

Runtime (6 bytes 0x606060405200, SHA-256 eb04cef0…) and creation (40 bytes) both reproduce byte-for-byte. Source `contract Stub { address owner; function Stub(){ owner=msg.sender; } }` compiled with soljson v0.1.5+commit.23865e39, optimizer ON — matching the sibling Marriage Registry deployed 89 seconds later from the same address. The tight init (CODECOPY offset 0x22, no trailing STOP pad) rules out v0.1.1.
