The Story of Hashing

Deep End Era. Engineering with Sankalp · Oct 10, 2026 · 1h

A hash function looks small, but it sits underneath databases, caches, security and distributed systems. Trace hashing from early lookup tables through collisions, probing and attacks that exploit predictable behavior. The episode then explores probabilistic and similarity techniques, distributing keys across changing server fleets, and content addressing with Merkle trees. The through-line is choosing the right kind of hash for the question, rather than treating every hash as interchangeable.
