Blockchain security
Blockchain security is a critical concern due to the potential threats posed by quantum computing. Here's what you need to know: Quantum Threats to Blockchain - *Vulnerability to Shor's algorithm*: Quantum computers can potentially break the cryptographic algorithms used in most blockchains, such as RSA and elliptic curve cryptography (ECC), using Shor's algorithm. This could compromise the security of transactions and data on blockchain networks. - *Harvest now, decrypt later (HNDL) attacks*: Hackers can record encrypted data now and wait for quantum computers to become powerful enough to decrypt it later, posing a significant threat to blockchain security. Blockchain Security Measures - *Post-quantum cryptography (PQC)*: Researchers are developing PQC algorithms, such as lattice-based cryptography, hash-based signatures, and multivariate quadratic equations, to withstand quantum attacks. - *Quantum-resistant blockchains*: Some blockchain networks, like Algorand and QRL, ...
