Proving a Document’s Existence Without a Trusted Third Party
CryptomonnaiesIA helps you understand crypto and Web3, but also how to use blockchain for a concrete need: timestamping and sealing a file (contract, quote, creative work, proof of authorship) with a cryptographic fingerprint that can be publicly verified.
Blockchain Notarization: The Principle in 10 Seconds
- You upload your file → we compute its SHA-256 hash (a unique digital fingerprint).
- A proof is anchored on the blockchain → date + transaction + network become publicly verifiable.
- You download a PDF certificate summarizing the proof and how to verify it.
Why It’s Professionally Useful
- Intellectual property / creative work : prove that a document existed at a specific date (pitch, design, script, prototype).
- Deposit proof / traceability : versions of contracts, deliverables, specifications.
- Compliance : log decisions, reports, procedures (internal audit).
- Freelancers / agencies : secure exchanges (client brief, quote, transfer of rights, delivery).
No financial advice or performance guarantees. Blockchain notarization does not replace a lawyer or notary — it provides a technical proof (hash + timestamp) that can be independently verified.
Understanding Crypto and Web3 Technologies
CryptomonnaiesIA is an educational platform dedicated to understanding cryptocurrencies, blockchain technology, and emerging digital use cases.
No financial advice or promises of returns are provided. The content aims to explain mechanisms, risks, and core principles before making any decision.
