Historical Significance

Deployed from Vitalik Buterin's personal deployer address (0x1db3439a) on October 30, 2016. Compiled with Solidity 0.4.4, adding the non-payable function guard pattern introduced in 0.4.x. The sibling contract at 0x117a8de2 uses identical source but the older 0.3.6 compiler, making these two contracts a unique pair showing compiler evolution.
