What is nChain Sign?

nChain Sign is a digital signature service that utilises the unique benefits of blockchain technology to provide a secure, immutable, and transparent method for signing and verifying documents. It is designed to offer individuals and organisations the ability to execute signatures on digital documents with the assurance that once a document is signed, it cannot be altered without detection. It aligns with the principles of Web3 and Self-Sovereign Identity (SSI), emphasizing user empowerment. This service supports the notion of users owning their private keys, giving them full control over their digital identities and signatures.

Product Summary

nChain Sign provides a user the ability to submit documents, send it to the required signees, and collect signatures. The signing process is both visual (a traditional representation of signatures on the document) and enforced by cryptographic proof. This also provides proof that the document has been signed by the intended person.

Hashes of the signed document are published on blockchain. This allows users to track document history in a transparent manner, with encrypted details about the signature.

In a future release, nChain Sign will be integrated with our Digital Identity solution, enabling signees to link their signature to the necessary elements of their digital identity. This feature will be an additional reinforcement in the security of the digital signing process.
