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.
№ 002EthereumEthereum's Keccak-256 vs SHA-3: Same Sponge, Different Hash
Ethereum uses Keccak-256, not NIST SHA-3. Same sponge construction, different padding, different output, and the gap has broken real production tooling.
