14% of nodes in the Bitcoin blockchain are susceptible to hacking

The developers of the first cryptocurrency announced problems in the blockchain code. 13.7% of computers connected to the network are vulnerable to remote access. The bug affects nodes running Core software prior to version 25.0.

The flaw allows an attacker to exploit an assertion in code that handles block transaction messages (“blocktxn”).

And For the first time, Chinese scientists have cracked cryptographic algorithms using a quantum computer.

Researchers from Shanghai University have used quantum annealing to attack the algorithms that support encryption used in cryptocurrencies.

This is the first time a quantum computer has posed a real threat to encryption, although technical limitations remain. $BTC #BTC☀
