Identical-runtime sibling. Block-height timelock (Homestead, Apr 2016) that releases its full ETH balance to a fixed beneficiary at releaseBlock, self-schedulin
Historical Significance
Connects to Piper Merriam's Ethereum Alarm Clock, where the constructor pays the Scheduler to poke this contract's fallback at the release block, an early on-chain scheduling pattern.
Context
Compiled with soljson-v0.1.3 (optimizer ON); exact match of the 205-byte runtime. One of 26 byte-identical deployments.
Key Facts
Source Verified
Exact runtime bytecode match. Runtime: 205 bytes (byte-for-byte), compiled with soljson-v0.1.3+commit.028f561d, optimizer ON. Creation bytecode is native-build scope (deployed with a v0.2.0-nightly solc that the Alarm Clock Scheduler itself used); runtime-exact, same scope as the coin-0x012a5642 proof.
Homestead Era
The first planned hard fork. Removed the canary contract, adjusted gas costs.
