Check Signature

Private-public key cryptography allows you to sign arbitrary messages. Anyone can take the output of such a signature and verify its validity.

By consistenly signing work, one can build a reputation-based, self-governed identity noone can take away.

With this app, you can use your Ethereum Account to sign structured statements and share them in private or publicly.

1. Private: Create signatures directly in your browser and share the URL. Your data is not stored on our infrastructure.
2. Public: Publish your signature to IPFS and our APIs to make them publicly available and indexable.
3. Onchain (soon): Write your signature to the blockchain and create an immutable timestamp and historical proof of your message.

Signature Schema

The signed statements use a typed message format, including one or many Subjects, an Action, and an Object. Subjects are Ethereum Accounts, Actions are structured verbs like said or made, and objects are any plain text content, or URIs to content on the internet.

const name = 'Notability Check'
const domain = {
  name,
  version: '1',
}

const types = {
  [name]: [
    { name: 'Subject', type: 'address[]' },
    { name: 'Action', type: 'string' },
    { name: 'Object', type: 'string' },
  ],
}

cnost schema = {
  primaryType: name,
  message: {
    Subject: ['0xc8f8e2F59Dd95fF67c3d39109ecA2e2A017D4c8a'],
    Action: 'said',
    Object: 'this artwork may or may not be notable',
  },
  domain,
  types,
}
