Historical Significance
The 'hello world' of Solidity: the first example from the official documentation, storing and returning a single integer.
Context
Compiled with soljson-v0.1.5 (optimizer OFF); exact match of both the 151-byte runtime and 167-byte creation bytecode. One of 18 byte-identical deployments.
