Historical Significance

The Greeter was the first smart contract most Ethereum developers ever deployed. It appeared in the official go-ethereum wiki and across early Ethereum learning materials as the standard introduction to Solidity programming.

Description

Deployment of the canonical Solidity Greeter tutorial from the official Ethereum documentation. The contract uses the two-contract inheritance pattern (mortal + greeter) that demonstrated constructors, string storage, owner-restricted self-destruction via suicide(), and the constant function modifier. This instance was initialized with the greeting "Hello World!". The deployer (0x65c13da4) deployed 79 contracts between August 2015 and April 2017, including other tutorial contracts such as the Coin example, suggesting a developer systematically working through the official Solidity documentation.
