Quantum computing threat to crypto wallets isn't sci-fi anymore. Breaking down the math: ~26 days of computation per key attempt with roughly 50% success rate means an average of 52 days to crack a single private key.
The attack vector is clear - high-value wallets become priority targets first since the computational cost needs to justify the reward. Think whale wallets holding millions in $BTC or $ETH.
This isn't an immediate doomsday scenario, but the timeline is compressing. Current ECDSA and SHA-256 schemes that secure most blockchains weren't designed with quantum resistance in mind.
The technical gap: we need post-quantum cryptographic standards implemented at protocol level before quantum computers reach the threshold where 52 days becomes 52 hours. Projects working on quantum-resistant signatures and lattice-based cryptography are worth tracking now, not later.
The transition window is narrowing - migrating billions in on-chain assets to new cryptographic schemes isn't something you can rush when the threat materializes.
