Quantum Computing and Blockchain: Threat or Opportunity?

TL;DR Quantum computing poses serious risks to the security of blockchains, but it also offers opportunities for innovation. Shor’s and Grover’s algorithms could break the current security of blockchains, affecting private keys, digital signatures, and hash functions. Despite the risks, quantum computing could also optimize processes within blockchains and encourage the creation of new, more... source: https://crypto-economy.com/quantum-computing-and-blockchain/
