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?
What you’re describing kinda just sounds like ID cards or passwords… I mean, these can be stolen, falsified ot lost, but even assuming the “falsified” part is and remains impossible, couldn’t it be possible to obtain or duplicate someone’s token? The crudest example I could think of would be someone just stealing a computer on which someone else’s crypto keys are saved, but through hacking there’d probably be more ways to do it…
From my understanding (and it could be wrong tbh, this is a bit out of my wheelhouse), you cannot duplicate NFTs - it’s already recorded on the blockchain, so it’ll be the only unique one on the chain. Even if somebody were to create another token with your info, you can still say that the duplicated token is not your token because you can prove when the duplicated one was created after your token was, and can even prove each transaction done with your specific token. Plus, to even hack the blockchain, iirc it would require one party to have over 50% of the processes running it - which is reportedly hard to do, so take that for what you will.
