Blockworks Analytics (@blockworksres) is an incredible resource for tracking some of the most important metrics in the crypto space. And many of their charts are free (don’t even need to sign up). Here are a few of my favorite free charts I like to monitor to keep a pulse on what’s going on on-chain. 1. Network Real Economic Value (REV) This chart captures the “real economic value” across different Layer 1 blockchains, which is calculated by adding transaction fees and priority fees/tips to approximate demand for transacting on each network. Ethereum was super high back in 2022–23 when network demand drove exceptionally high transaction fees. Solana moved into a dominant position in mid-2024, and Hyperliquid has just recently taken the top spot (though I think it’s odd to include Hyperliquid here since they do have an L1, HyperEVM, with REV below $100k per week).
