Identical-runtime sibling. Block-height timelock (Homestead, Apr 2016) that releases its full ETH balance to a fixed beneficiary at releaseBlock, self-schedulin

Homestead EraVerified Source

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.

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.
