Proxy patterns enable smart contract upgrades, but storage slot collisions can silently corrupt funds, the mechanism, the tradeoffs, and what auditors check.
№ 002SecurityVerifiable Delay Functions and Randomness Beacon Security
VDFs make on-chain randomness manipulation structurally expensive via a sequential delay no adversary can compress. The mechanics, caveats, tradeoffs.
№ 003SecurityFormal Verification vs Smart Contract Security Audit
A security audit finds likely bugs. Formal verification proves their absence mathematically. The difference in cost, time, and guarantees, laid out plainly.
