One of six HelloWorld Greeter deployments by Linagee on Ethereum Frontier Day 1 - same source, same compiler, greeting: 'Hello World!'
Historical Significance
Part of a wave of Linagee HelloWorld deployments on Frontier Day 1. Shows the early developer practice of repeatedly deploying contracts to test or demonstrate functionality on the live network.
Key Facts
Description
Deployed by 0x3D0768 on August 7-8, 2015 - the same address that deployed the first successful HelloWorld on Ethereum (block 48,681). Linagee deployed the canonical Frontier Greeter tutorial at least 6 times with the 'Hello World!' greeting, plus a seventh instance with 'Welcome to Walmart I love you!' All share the same bytecode base: soljson v0.1.1 optimizer OFF, mortal + greeter inheritance pattern.
Source Verified
Creation TX matches: compiled Greeter bytecode (692 bytes) + ABI-encoded constructor arg 'Hello World!' = 788 bytes. Compiler: soljson v0.1.1+commit.6ff4cd6a, optimizer OFF.
Heuristic Analysis
The following characteristics were detected through bytecode analysis and may not be accurate.
Frontier Era
The initial release of Ethereum. A bare-bones implementation for technical users.
