Google’s Willow is pushing quantum from lab demo to usable prototype. @Google The blockchain security stack must be rebuilt for the post quantum era. Shor’s algorithm breaks schemes based on factoring and discrete logarithms including Bitcoin ECDSA and Schnorr on secp256k1, @ethereum account level secp256k1, and BLS at the consensus layer. Worth noting, Grover speeds up hash search such as SHA 256 only quadratically; raising security levels preserves margin. The urgent items are signatures and key establishment. #FHE will be the core infrastructure for privacy and quantum resilient compute. It keeps computation inside the ciphertext domain end to end and avoids data in use exposure. FHE has natural quantum resistance due to its architectural choices and built in elasticity. Built on lattice problems such as #LWE and #RLWE, it is inherently immune to Shor style exponential attacks that target specific algebraic structures such as integer factoring, and it scales security by tuning parameters for example increasing ring dimension to quantitatively offset risk.
