An ethereum.org 'Hello World' greeter (mortal + greeter): greet() returns its stored greeting, kill() selfdestructs to the owner. One of 68 byte-identical Front
Historical Significance
The reference 'Hello World' contract from ethereum.org's early documentation, deployed at least 68 times in the Frontier era - among the most-copied early Solidity contracts.
Context
Frontier-era greeter from the ethereum.org tutorials; 41 of the 68 identical-runtime deployments remain live on-chain, the rest self-destructed via kill().
