Signchain 📝 🔑

Digital signing platform for legal documents

We have been working on an Arbitration platform for some time. While dealing with a large amount of agreement documents, we felt that there is an absolute need for digitizing the signing process of such documents. That's when we started ideating around the digital signing platform (Signchain). Read more on the inception of Signchain here.

We know that there have been plenty of efforts in the area of electronic signing. But the existing solutions don't seem to operate on standards that are openly verifiable and interoperable. In Signchain, we want to address the age-old issues of document signing such as tampering, delayed process, verification troubles, with the help of decentralized storage and open verification. We also want to address the interoperability concerns by using standardized identity, storage, and signing protocols.

We created a basic platform where users can share the document privately with other counterparties that need access and sign the document. Whenever any party signs on the document, the proofs (standard digitally signed data) are recorded. The proofs of the signatures can be verified by anyone on the platform while only certain parties will have access to the document. The identity of all the parties can also be verified as the credentials are maintained using decentralized identity standards

Technologies/ protocols used:

• Fleek APIs to store the encrypted documents on IPFS
• Textile ThreadDb to store signatures proofs of documents
• Ceramic IDX for decentralized identities

quickstart

git clone https://github.com/signchain/core

cd core

yarn install

you might get node-gyp errors, ignore them and run:

yarn run start

in a second terminal window:

yarn run chain

in a third terminal window:

yarn run deploy
