Except we don't need a blockchain for it: just publish it in a well known place where others can collect it.

- jacquesm 9y agoThey are suggesting a blockchain to prevent mutation of the publication (pun intended) after the fact.
- majewsky 9y agoThe "where others can collect it" part solves that: Suppose that university A announces their study method and university B makes a mirror. Then if A were to forge the announcement after the fact, B could tell. (You would need cryptographic signing, though, to see if the record mirrored by B has not been tampered with.)
- jacquesm 9y ago> (You would need cryptographic signing, though, to see if the record mirrored by B has not been tampered with.) Yes, hence the blockchain, which provides all that in a fairly convenient package. You could even piggyback on any existing public blockchain, for a few fractions of a penny.
- Dylan16807 9y agoIf you're making a notary system, the part you can get from a blockchain is a very minor percent of your code, and comes with a lot of complicated baggage. It's not convenient at all.
- ClassyJacket 9y agoYou could also just distribute a hash of, or the entire original text of, the original text. No need for a blockchain and all that processing.
