Engineering notes from the blockchain-compression team — Zstandard dictionaries, ratio honesty, and chain-specific structure.https://blockchain-compression.cryptuon.com/en-ushttps://blockchain-compression.cryptuon.com/blog/generic-compressors-and-chain-data/https://blockchain-compression.cryptuon.com/blog/generic-compressors-and-chain-data/Vanilla zstd is excellent at what it does. What it does is rediscover common byte patterns on every compress call. Here is why that matters for Solana data, and what a hardcoded dictionary actually buys you.Fri, 22 May 2026 00:00:00 GMThttps://blockchain-compression.cryptuon.com/blog/measuring-ratios-that-matter/https://blockchain-compression.cryptuon.com/blog/measuring-ratios-that-matter/The headline 60:1 in our README is the top of one preset's range on archival data. Here is how we measure compression ratios honestly, why the lower bound matters more than the upper, and how to benchmark on your own workload.Tue, 05 May 2026 00:00:00 GMThttps://blockchain-compression.cryptuon.com/blog/reading-the-algorithm/https://blockchain-compression.cryptuon.com/blog/reading-the-algorithm/A walk through the actual source of the Solana preset — the dictionary patterns, the Zstd construction, the preset-to-level mapping. Nothing magical, mostly a small constant table feeding a well-tested encoder.Mon, 20 Apr 2026 00:00:00 GMT
