Blockchain is an unchangeable (unless you own the only authority as we've seen, or you fork it) database that can only grow. It HAS to have multiple, identical instances or the owner can corrupt it. I'm not sure I see any benefit here except for potential security. But we've seen blockchains get into the terrabytes pretty quickly which isn't that feasible for large-scale operations.
You're right about that for sure. But a few TB isn't that big a deal anymore, and if there was a need to deal with it we could come up with something.. or just not use it at all. ๐
How do you ensure you are holding an accurate copy of the blockchain in that case? A single holder of a blockchain means the entire thing is insecure and the holder can change or steal whatever they want.
If a new player wants to host a copy of the etherum blockchain, how do they do that when it's stateless?
