What was the length of the transaction identifier hash been increased?
The greater the length of the hash, the more difficult it is to calculate (hack) transactions.
This makes blockchain more secure.
That needs more time to break down but what about the possibility of quantum computer to do that?
But i thought that crypto needs to upgrade the current hash. But like bitcoin used the reversed hash method as explained by one of the bitcoin core developer. Isn't the TXHash was contained the detail related to the transaction ID? i think it's.
When a quantum computer is invented, there is a greater likelihood of hacking into all existing blockchains.
