Quantum Risk to Blockchain

With all of these advances, some of the algorithms combined and advanced the state of the art against elliptical curves far faster than expected.

PSIQuantum has created algorithms capable of breaking 256 bit public keys into the private key using a 1152 qubit physical system, networked together.

By using several advanced techniques the paper estimates a 10 minute average time to solve for private keys.

They are competing with IBM and Atom Computing who make this hardware, and plan to have a 1 million qubit system online by 2027.

All blockchains need Post Quantum Safe public and private keys.

While hashes can be changed with a fork, changing public-private keys means the balance of the entire network becomes 0.

The only solution is to migrate to a new network that implements quantum safe cryptography.
