A Frontier Greeter compiled with an intermediate soljson build - same source as the standard tutorial, slightly different string return codegen.
Historical Significance
One of the earliest Greeter deployments, providing evidence of an intermediate Solidity compiler build in circulation during Frontier week 1.
Context
Deployed during the Frontier era using the canonical mortal+greeter tutorial. The deployer also deployed a Coin stub at rank 40, both likely via the same tool.
Key Facts
Description
A Greeter contract deployed at block 52,918 (August 8, 2015) using the standard ethereum.org tutorial source (mortal + greeter inheritance). The first 352 bytes of runtime are identical to the canonical standard greeter family. The final 105 bytes differ due to a variant string return codegen, producing a 457-byte runtime vs the standard 476 bytes. This indicates compilation with an intermediate soljson build between v0.1.4 (which produces 476b) and v0.1.5 (which produces 542b) - likely a nightly or Mist-bundled build from early August 2015. Same deployer (0x4b0c6f02) as the Coin stub at rank 40.
Source Verified
near_exact_match: first 352/457 bytes identical to standard greeter (73%). Diff is string return codegen only. Source is the standard mortal+greeter tutorial. Compiled with intermediate soljson between v0.1.4 and v0.1.5.
