Alongside blockchain engineering, I am currently studying Quantum Computing through the Indian Institute of Science (IISc), Bengaluru. It is part of a deliberate habit of continuous technical development — following the next shift in computing and the cryptography that blockchains depend on.
The questions I am learning to ask — framed as a student of the field, not as a claim of expertise.
Blockchains rely on elliptic-curve signatures such as ECDSA (secp256k1) and Ed25519. Shor's algorithm, on a sufficiently large fault-tolerant quantum computer, would break them — which is why post-quantum signature schemes matter to anyone designing long-lived on-chain systems.
Grover's algorithm offers only a quadratic speed-up against hash functions, so primitives like Keccak-256 and SHA-256 are far less affected. Understanding that difference helps separate real risk from hype.
Assets tokenized today — real estate, stablecoin reserves — may need to stay secure for decades. Designing for key rotation, upgradeable verification and migration paths is an architecture decision, not a future problem.
