Do you know the difference between blockchain.info "wallet" and Bitcoin Core "Full node"?
Not really and still learning. I guess everyone that has Bitcoin Core installed has a full-node?
What I mean is that surely blockchain.info wallets work with some kind of modified
bitcoind. and my question was how many
bitcoind full-node clients do they use to maintain so many users?
I'm also unsure of how blockchain.info "wallets" actually work.
