That's on the BSV chain, once CSW finally goes to jail for all his scams that chain will die just like hundreds of shitcoins have died.
The blockchain is not something that magically keeps data alive, it's the same as a torrent, if there are enough seeds the file will be available forever if nobody shares it or in the blockchain case, there is no full node available the chain is dead and nobody can retrieve the data anymore.
Blockchain, @stompix, cannot run out of full nodes or do you see a situation where it happens? at first glance you sounded like it can occur. However, I have a question, when they are no full nodes available and later on a full nodes connects to the network would they be a means of retrieving transactions that happened during downtime? what do you think will happen to the already stored transactions?
