is an open source project to validate the authenticity of a PDF document and the data it includes leveraging the immutability and security of the Bitcoin blockchain.How it works GitHub
Just upload a Verifiable PDF to the online validator and check if the document is the original or was tampered with in seconds. The validator is open source so anyone can host one. Moreover, any one is capable of verifying all VPDFs irrespective of who issued them.
You can test right now using the three sample VPDFs provided,
by downloading and drag’n’drop them to the dropzone above.
PDF documents can be verified on any validator by consulting the Bitcoin blockchain. Issuers can host a validator on their website, if they wish.
Any kind tampering of the PDF will immediately invalidate it as it will change the digital fingerprint that was anchored in the blockchain.
Straight-forward process using the most-widely used medium of exchange for documents. PDFs are already the de facto document format.
Following Bitcoin’s example we wanted our solution to be open and permissionless. The core library, which includes all the functionality, is open source and anyone can use it to issue, revoke and validate credentials.
