I know Stellar is designed for transfering funds and holding tokens, but I thought about using it for proof of existence. Stellars transaction fees are much cheaper than Ethereum and transactions are much faster. Could Stellar be used for PoE?
I would transfer lumen from my account to the same account (or another one I own) in a transaction and use the PoE SHA256 in the memo field, would this work?
When proofing existence, can I search all memo fields in Stellar for a SHA256?
