The attacker essentially reinitialized the contract by delegating by way of the library technique, overwriting the owners on the unique contract. It held a reference to a shared external library which contained wallet initialization logic. It produces giant (20kbyte) signatures that would bloat the blockchain (or create threat if stuffed in external storage). 247 exchange bitcoin While Bitcoin uses its blockchain to implement a ledger of monetary transactions, Ethereum uses its blockchain to report state transitions in a huge distributed laptop. Whether it is, then the solution could be easy.
