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?
I thought Git was a blockchain. Isn’t it?
This is my first time hearing this claim, and while I’m no expert, as far as I can say, not really. As said in another comment, they both use a similar principle (the “Merkle Tree”, which was invented in 1979), but Git was invented by Linus Thorvald in 2005 and the term “Blockchain” came with Bitcoin invented in 2008 by someone known as Satoshi Nakamoto (I did a little trip to Wikipedia for these dates).
