Algorand, a leading public blockchain network, is backing the Falcon algorithm against Quantum Computing assaults. Cryptographers and scientists around the world put forth over fifty potential algorithms as a response to the rise of Quantum computing technology that needs to be safeguarded. After extensive cryptanalysis, testing, and inspection, the National Institute of Standards and Technology (NIST) announced a set of cryptographic standards that are Quantum secure and amongst them, Falcon, designed by Craig Gentry, Chris Peikert, and Vinod Vaikuntanathan of Algorand, was chosen.

Falcon provides a more rigorous process of selecting valid signatures without exposing the signing key. It is the pioneer of blockchain technology with a quantum-safe digital signature system. Algorand will use Falcon signatures for a range of services, with State Proofs being the most recent advance in the Algorand blockchain. The importance of Quantum security, and Falcon's role in it, was addressed by Algorand Foundation CTO John Woods earlier.

State Proofs allow blockchains to operate in a decentralized manner with other blockchains and protect future forks in the chain caused by Quantum computing technology. Additionally, the operations performed through these proofs are also quantum safe. This ensures that the Algorand blockchain with its proven reliability, robustness and zero downtimes, has a successful future as Quantum computing advances.
