Description

Deployed by Vitalik Buterin and later self-destructed (historical bytecode preserved by EthereumHistory). This contract has identical bytecode to 0xa619c3df689ecb7ef3b99526a1a7599d2e443f65, which was verified as ListLogs. A minimal on-chain logging contract written in Serpent (canonical source list_logs/main.se in ethereum/dapp-bin): addLog(v) emits a Log(string) event carrying an arbitrary string, addBreak() records the current block number as a section marker, and getLatestBreak() returns it.
