For a long time, I thought of the blockchain as almost synonymous with cryptocurrencies, so as I saw stuff like “Odyssey” and “lbry” appearing and being “based on the blockchain”, my first thought was that it was another crypto scam. Then, I just got reminded of it and started looking more into it, and it just seemed like regular torrenting. For example, what’s the big innovation separating Odyssey from Peertube, which is also decentralized and also uses P2P? And what part of it does the blockchain really play, that couldn’t be done with regular P2P? More generally, and looking at the futur, does the blockchain offer new possibilities that the fediverse or pre-existing protocols don’t have?
But you would still need an authority that can unilaterally make changes to these ownership records. People die, things get lost, stuff happens. So it can’t all be based on signing with private keys of individual persons. At that point: Why not run a central database of it all. It’s cheaper, more efficient and you could still publish a public record for traceability.
I really don’t see any problem that Blockchain could solve better than other solutions. Except Cryptocurrency.
