OriginStamp.com vs Proof of existence

OriginStamp is a blockchain-based timestamping service that allows users to certify the existence of digital files or documents at a specific point in time. It uses blockchain technology to provide immutable proof of ownership and timestamping.

Proof of existence is a service that allows you to cryptographically prove that a document existed at a particular point in time. It works by submitting a hash of the document to a blockchain, which timestamp proofs its existence.
