Ethereum Trie Depth and Light Client Proof Costs
Ethereum's Keccak-256 state trie depth sets the floor for light client proof costs. Precise mechanics, worked numbers, and what Verkle tries actually change.
№ 002DeFiMerkle Proofs and Selective Disclosure in Digital Identity
Merkle proofs let you prove one credential claim without exposing the rest. Here is the exact mechanism, a worked example, and the tradeoffs that matter.
