This simple website allows you to publish commitments to text on Ethereum or other EVM-compatible blockchains. You can later to choose to reveal the text of the commitment to prove that you knew the text at the time of the commitment. This website is deliberately designed to be as simple as possible to make it easy to audit, so please excuse the lack of styling. Commitments made here are hashed with SHA-256 because support for SHA-256 is built into modern web browsers.
