Description

Deployed October 30, 2015 by Vitalik Buterin (0x1db3439a22ee7c4d034e9b26437d3960b5af0517). A pay-to-send on-chain email service written in Serpent. email(a, b, c) takes three strings (recipient, subject, body); if the caller sends at least 0.007 ETH, the contract emits an Email(string, string, string) event carrying the three strings and forwards the fee to the owner address stored at storage[0]. The message content lives entirely in the event log, a whimsical early demonstration of using Ethereum logs as a message bus. The 493-byte runtime reproduces byte-for-byte from the reconstructed Serpent source using ethereum/serpent commit 146cc8a (commit f0b4128 also matches). runtime sha256 ce909f0eea2f7dbe4006ff7359e56bbbab7ccab79bb92600466ee993f62c3404.
