SignRequest Uses Chainpoint To Anchor Documents To The Bitcoin Blockchain

What is SignRequest?
SignRequest provides digital signature solutions to small and medium sized businesses. The company launched in 2014, has currently over 100,000 clients in 32 countries, and provides services in 18 languages. SignRequest offers a web-based digital signature solution, developer API, and integrates with Salesforce, Google Apps, Slack, and other popular applications.
How does SignRequest use Chainpoint?
SignRequest uses Chainpoint to prove the integrity and timestamp of documents, by anchoring them to the Bitcoin blockchain. Since 2017, SignRequest has created a Chainpoint proof as part of their digitally signed documents. Documents are not stored in the blockchain, instead a unique (and unidentifiable) hash is published. This is useful if there is doubt about which version was signed and when it was signed. By checking if hash of a document exists in the blockchain the signers can validate the authenticity of a signed document.
“Chainpoint lets SignRequest customers prove the integrity and timestamp of digitally signed documents without the need for a trusted third party” - Michaël Krens, SignRequest CTO
Why did SignRequest choose Chainpoint?
SignRequest considered creating their own solution for anchoring documents to the Bitcoin Blockchain. After some initial experimentation they decided to look for an existing solution. Their team evaluated a variety of technologies, including Factom. SignRequest chose Chainpoint over Factom because it was faster, open source, and easier to implement.
It took SignRequest approximately one day to integrate Chainpoint with their product.
How can I learn more about Chainpoint?
Chainpoint allows software developers link data to the blockchain. This process generates a Chainpoint proof, which can be used to prove the data is linked to a point on the chain— hence the name Chainpoint.
Blockchains are notoriously slow. Bitcoin can process about four transactions per second. Ethereum can process approximately fifteen transactions per second. Chainpoint overcomes these scalability limitations by linking thousands or even millions of Chainpoint proofs to a single transaction.
