The second contract deployed by Piper Merriam on September 22, 2015, within hours of the Ethereum Alarm Clock v1, representing the first same-day iteration of t
Historical Significance
This contract documents the same-day iteration pattern of the Ethereum Alarm Clock development, showing that Piper Merriam deployed and tested multiple versions of the scheduling service within hours of the initial September 22, 2015 launch. It reflects the rapid, live-mainnet development style characteristic of the early Ethereum Frontier period.
Context
In September 2015, Ethereum's test networks were not yet mature or widely used. Developers commonly deployed and tested contracts on the live Frontier mainnet. Gas prices were low and ether had relatively little monetary value, making mainnet experimentation feasible. This deployment captures the iterative development cycle that early Ethereum infrastructure builders used to rapidly refine their contracts.
Key Facts
Description
This contract was deployed at block 274899 on September 22, 2015, approximately twelve hours after the first Ethereum Alarm Clock deployment at block 273762 by the same address (0xd3CdA913deB6f67967B99D67aCDFa1712C293601). The contract was deployed with 2,328 bytes of bytecode and received five transactions, including interaction calls within the same hour of deployment.
The rapid follow-up deployment on the same day as the initial launch indicates early testing and iteration of the scheduling service. Blocks 274905 and 274925 contain interaction calls with 74-byte inputs, suggesting function calls against the newly deployed contract. A call at block 274927 with a 138-byte input likely represents a more complex scheduling operation. A final interaction at block 275985 completed the initial test cycle.
Piper Merriam described working extensively on the Ethereum Alarm Clock after launch, fixing attack vectors and refining the game theory for executor incentives. This same-day iteration is consistent with that pattern of rapid development: identifying issues or improvements in the initial deployment and immediately producing a revised contract.
The deployer's activity on September 22, 2015 demonstrates the development pace common among early Ethereum infrastructure builders: deploy, test, and revise within hours using live mainnet as the testing environment, a practice that was typical in the Frontier era before testnets were widely used.
