[DocuSign](https://www.docusign.com/products/blockchain) is a commercial solution available integrated with the Ethereum blockchain. In this solution, only the document signature is stored in a blockchain (currently only Ethereum), and the solution does not support storing nor sharing/transferring the document. One needs to have a copy of the document to verify the signature: "Anyone with a copy of the agreement can check it against the blockchain-stored evidence to verify the copy's integrity against the original DocuSigned file." AdaStamp offers added value to DocuSign and similar solutions by allowing storage and sharing of documents that are to be signed.
