Kaspa as an immutable seal

I am taking Kaspa as part of a project for a cryptographic anchor of document has a lot. The idea is not to store documents in the chain, but only their hash so that they can demonstrate their integrity and the existence of a particular version at a given time. I think Kaspa’s speed and performance could make it a very interesting use case. Is anyone else exploring something similar?

I am convinced that I will have this wonderful community in the future and bring a lot of use to our network.

I like this idea a lot. Just hash the document locally, put that hash or a Merkle root into a Kaspa transaction, and later anyone can verify:

file → hash → proof → Kaspa txid

Where it gets more interesting is when this stops being a one-off timestamp and becomes a real registry.

For example:

  • the same document has multiple versions
  • an issuer needs to sign or control the seal
  • a seal can be superseded or revoked
  • many documents are batched together, but each user only reveals their own proof
  • a verifier wants a standard proof package instead of manually checking raw tx data
  • private documents should stay private, while the public chain only sees commitments

Many simple and complex things can be done using low costs and on a sovereign consensus that will soon be confirming the speed of the Internet, work on it
