    What other solutions to double spending were there in financial cryptography before?

      No idea, I don’t work in fintech, but was it a fundamental problem that required a solution?

      I’ve worked with blockchain in the past, and the uses where it excelled were in immutable bidding contracts for shared resources between specific owners (e.g. who uses this cable at x time).

        Fully decentralized p2p cryptocurrency transactions without double spending by proof of work (improvement upon Hashcash) was done first with Bitcoin. The term fintech did not exist at the time. EDIT: looked it up, apparently first use as Fin-Tech was 1967 https://en.wikipedia.org/wiki/Fintech – it’s not the current use of the term though.
