According to recent research, it has become economically unfeasible to carry out a Byzantine Fault Tolerance (BFT) attack on Bitcoin and Ethereum. Hence, anyone attempting to take over control of any of the two blockchain networks would be doing so at a loss.
An original hypothesis on the possibility of taking over the Bitcoin and Ethereum blockchain networks suggests that any user controlling 51% of all Bitcoin nodes could dictate the networkâs operations. Similarly, with a 34% attack, a user can manipulate the consensus of the Ethereum ledger.
