Can Blockchain technology improve the security and transparency of eSignatures?

All answers to this question.

It’s great for permanent records, but for most everyday contracts, it might be overkill compared to a standard PDF signature.

• True, Betty. But for high-value assets, that extra layer of decentralization is becoming a huge selling point for enterprise clients.

Doesn't storing document hashes on a public blockchain raise privacy concerns, even if the document itself is stored off-chain?

   Answered 2024-07-18 by Daniel Martinez

• Daniel, a hash is a one-way function. You cannot reverse a hash to see the document content. As long as you aren't putting PII (Personally Identifiable Information) on the chain, it's perfectly safe and follows GDPR "privacy by design" principles.

The main advantage of blockchain here isn't necessarily the signature itself, but the "Proof of Existence." Traditional signatures rely on the certificate authority (CA) remaining in business for 20 years to verify the signature. With a blockchain, you can anchor the document's hash to a public ledger like Ethereum. This provides an immutable, timestamped record that is independent of any single vendor. In a 2024 project, we used this for real estate titles to ensure that the chain of custody could be verified even if our company’s servers went offline.
