eth_getProof archive format sneak peak. 100% of historical Ethereum mainnet proofs in 5 TB (+3.2 TB of data) vs 20 TB (Geth/Nethermind) This is probably the most "difficult" problem I have worked on so far. not as impactful as other things I built but the solution to this problem is defo the most complicated and involves a lot of entropy-oriented thinking.
