"You can save 10x on cost just by refining the data." @n0slav talks about the Medallion Architecture, the pattern that makes chain data actually queryable for apps. It works in three layers: • Bronze: raw firehose, everything the chain emits • Silver: enriched with ABI decoding, token metadata, USD pricing • Gold: app-ready data like DEX swaps and OHLCV candles Each layer compresses the one below it. On Base, 90 terabytes of raw block data shrinks to 1.2 terabytes by silver. By gold, apps query only what they need. We run the full pipeline. Bronze to gold, across 100+ chains.(Covalent)
