These are abstractions - people use abstractions to make a point. - Economic Node: a full node run by an entity that actually moves real BTC in/out of the economy - exchanges, custodians, merchants, payment processors, mining pools, large wallets. Miners connect to them to source transactions. These nodes don’t just enforce consensus rules, they also apply policy rules (filters) that decide what gets into the mempool. - Economic Weight: the influence those nodes have over consensus and miner incentives. If they reject a block, miners can’t sell it into the market - the block becomes worthless. Nodes >> Miners - by design. Nodes define consensus, miners follow it. Without node validation, miners are just hashpower on a fork no one accepts. That’s why Core devs used to tell miners: ‘Adopt these mempool filters or risk getting orphaned.’ So yes, abstractions - but describing very real dynamics. Economic weight is as real as miners’ incentives: ignore it and you’re on a fork no one trades on. An economic node is as real as the users and miners it connects - ignore them and your blocks become worthless. Bitcoin’s security isn’t just SHA-256 - it’s consensus enforced by nodes.
