Welcome to Dedit API Documentation

Dedit.io is the blockchain-based platform for secure and efficient document notarization, signing, storage, and sharing.

Why Dedit

An increase in remote collaboration and data exchange on the web also means an exponential rise in risks: plagiarism, counterfeiting, cyber-attacks, and apocryphal signatures.

With blockchain notarization (and tokenization) you can protect yourself and your business from such risks through proof of existence, proof of paternity, and proof that a file has not been tampered with.

With Dedit you have a one-stop shop, one convenient solution to:

  • prove the authorship of a document, contract, project, file;

  • share safely your files with third parties;

  • sign agreements and contracts with increased security;

  • store sensitive files in an encrypted, GDPR-compliant vault. You are the only one that has access and can read the files unless you decide to share them with someone.

What is a notarization

For each file, you can store a digital fingerprint (hash) on the blockchain, which can’t be modified anymore and serves as proof of the original document. Once you write a hash on blockchain, it is registered with a timestamp (in Italy it has legal value as per art. 8-ter of D.L. December 14, 2018, n. 135, converted in law with L. February 11, 2019 n. 12).

What are Dedit's blockchain signatures

With Dedit users can sign the notarization of a certain file and subsequently invite other people to sign as well.

When registering with Dedit, even in the case of log-in via the Italian Digital Identity SPID, to sign a document, users need to request a temporary 6-digit code which will be sent to their mobile device or email. Once received, they must enter the 6-digit code to unlock the signature. ​

In this way, the tenant must enter the following:​

  • something that only the user knows (the password);​

  • a code received on something that only the user owns (the smartphone).​

Thanks to the document hash, the timestamp, and the public key stored in the blockchain the document, the signature, and the associated data are protected from future modifications.​

With this added security, Dedit's signatures are Advanced Electronic Signatures.
