Sign Service

The goal of this raid is to create a web service that allows users to upload, sign and store the hash of documents on the blockchain and to

Functionalities

Our signing service consist of three sections.

  • Title and short presentation of the service
  • Upload a document and connect a wallet
  • Actions : sign, publish and verify

Presentation This section introduces the service and redirects to the two other pages

Connection

  • a button to upload a document to the webpage
  • a button Connect Wallet to connect an Ethereum wallet. It should handle MetaMask. Optionnaly you could use wallet connet

Action

  • a button sign offline to sign the document offline
    • The resulting signature is displayed on the page or in a modal
  • a button publish to store hash of the transaction on the blockchain
    • The transaction is created to add the hash to a smart contract.
    • The transaction is signed by the wallet and send
    • Optionally : The document can be stored in the database of your choice
  • a button verify to check if a document has been stored previously. - It hashes the document, reads if the smart contract contains it, and displays the data at which the document was added Optionally
  • A retrieve section allows to recover a document from its hash. The document must have been stored

Result

The overall appearance can be basic but it should be clear and easy to use.

Scripts and documentation

Package.json must contain following scripts:

  • deploy that compile and deploy the smart contract with the tooling of your choice on a local blockchain (that must be launched too)
    • If the tooling is not available it should instruct the user how to install it
  • serve that launches the server that serves the page on localhost:3000
  • start that does all of the above

The project must contain a readme file that introduces the project and instructs how to use i
