Bytecode verified via sibling
This contract shares identical runtime bytecode with SimpleStorage (0x07d39cea...) which has been verified through compiler archaeology.
The SimpleStorage tutorial contract with a log event added to its setter.
Historical Significance
SimpleStorage is the first contract in the Solidity documentation: one stored number, a set(uint256) and a get(). This version adds an event, log(uint256), fired from set before the write, which is how a 2015 developer watched a transaction land before there were block explorers that decoded storage. Source recovered by exact bytecode match: solc v0.1.1+commit.6ff4cd6 with the optimizer on reproduces all 119 bytes of the creation transaction.
Context
Deployed in 2015 on the Ethereum Frontier network.
