If you wanted to break bitcoin couldn't you just setup a powerful computer to just transact millions of BTC micro transactions back and forth to make the blockchain super huge.
Somebody said its already upto 15GB
What is someone sabotaged it like this and the blockchain became several terabytes of a few petabtyes.
Would that bring all wallets to a grinding halt?
What you will see in the future is fewer and fewer people keeping the blockchain on their devices. The blockchain will be stored and protected mostly by pools, exchanges, and corporate entities like blockchain.info.
