[Lex Computer & Tech Group/LCTG] Researchers claim quantum device performs 9, 000-year calculation in microseconds

[Jerry Harris]

As of today, the private keys used to grant access to an account on the
Blockchain are vulnerable to quantum attacks. Likewise, Blockchain
encryption is also vulnerable and could lead to somebody gaining control
over the public blockchains and/or changing data that is deemed immutable.

There is still time to develop quantum-proof public/private key creation
and Blockchain encryption. One more significant todo on the list.
