Proof of existence vs Stampery

Struggling to choose between Proof of existence and Stampery? Both products offer unique advantages, making it a tough decision.

Proof of existence is a Bitcoin & Cryptocurrency solution with tags like blockchain, timestamping, proof, cryptography.

It boasts features such as Allows users to cryptographically prove a document existed at a particular point in time, Uses blockchain timestamping to prove document existence, Users submit a hash of the document which is recorded on the blockchain and pros including Provides immutable proof of existence for documents, Low cost way to prove existence compared to notarization, Does not require revealing actual document contents.

On the other hand, Stampery is a Business & Commerce product tagged with timestamping, blockchain, certification, cryptography, proof-of-existence.

Its standout features include Timestamping of documents, photos, videos, and other files by storing cryptographic hashes on the Bitcoin blockchain, Verification of timestamps through provided cryptographic proof, Timestamp certificates with detailed metadata, Developer APIs and integrations, User dashboard to view timestamp history and manage accounts, and it shines with pros like Strong cryptographic proof that documents existed at a certain point in time, High credibility and immutability by leveraging the Bitcoin blockchain, Easy to use with no blockchain knowledge required, Affordable basic pricing tier, Integrates with many applications and services.

Product Overview

Proof of existence

Description: 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.

Stampery

Description: Stampery is a blockchain timestamping service that allows users to certify the existence of documents by storing hashes on the Bitcoin blockchain. It provides cryptographic proof that digital assets existed at a certain point in time.
