These methods build redundant networks via hash functions, digital signatures, and asymmetric cryptography. However, attacks employing quantum computers that take advantage of Grover and Shor’s algorithms can compromise the security of the current blockchain architecture.enHyperledger FabricPost-quantum cryptographyDigital signaturesOQS libraryOther
