One of six HelloWorld Greeter deployments by Linagee on Ethereum Frontier Day 1 - same source, same compiler, greeting: 'Hello World!'
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.
