The go-ethereum Contract Tutorial greeter, deployed from a variant whose constructor differs from the published one.
Historical Significance
A copy of the tutorial greeter whose runtime is recovered but whose deployment is not, which is a common shape in this material: the compiler settles the runtime while the constructor keeps whatever the author edited.
Context
The Contract Tutorial on the go-ethereum wiki, included by reference from the Frontier Guide, was the standard introduction to Solidity through 2015. Its greeter is the contract most readers deployed first.
Key Facts
Description
The greeter of the Contract Tutorial on the go-ethereum wiki: a mortal base holding the account that created it and offering a kill() only that account can call, and a greeting string returned by greet().
Its runtime code matches the tutorial's greeter exactly, so the contract behaves identically to every other copy. The deployment code does not: whoever deployed it changed something that only affects construction, so the exact source that produced this transaction has not been recovered even though the contract on chain is understood completely.
