Crypto On-Chain Analytics (multi-chain) - BTC + ETH daily network fundamentals, cleaned Parquet
Daily on-chain fundamentals for Bitcoin AND Ethereum in one clean panel - computed directly from the public-domain blockchains (via Google BigQuery public datasets, not a restrictive wrapper API). BTC: transaction count, block count, block size, fees, on-chain volume, average transaction value, outputs created / inputs spent, and ACTIVE ADDRESSES. ETH: transaction count, gas used, average gas price (gwei), ETH transferred, active addresses, and ETH burned (EIP-1559). Active-address counts and on-chain throughput are the metrics analytics vendors (Glassnode, Coin Metrics, DefiLlama, Blockchain.com) sell behind paywalls and forbid you to resell - but the ledger itself is public-domain data, so these derived aggregates are freely redistributable. That licence gap is the moat: the clean, resellable on-chain-activity layer.
