Albeit 1.6PB/day may be somewhat exaggerated, comparing Binance to Ethereum needs much more consideration including:

- Ethereum's transaction throughput is normally 12~20tx/sec so there cannot be a "high-frequency trades" on Ethereum smart contracts with naive contract interaction(it will cost enormous fees). There are scaling concept like "layer-2" or "layer-3", but they still cannot beat highly optimized centralized server applications. Decentralized exchanges have different schemes to centralized ones to reduce txs to discover the price(keyword: AMM, "automated market maker")

- The transactions per sec metrics are just recording "confirmed" txs by the blockchain, and many "retail-squeezing" trading txs (called MEV, maximal value extraction) are competing behind the blockchain and only one tx is chosen by the blockchain, which will rebate most profits to the blockchain validator(which is analogous to the HFTs on the centralized exchanges).

- The blog post's argument would count all logs of intermediate hops, like L7/L4 proxy and matching engine and so on, and Ethereum's full node storage is only a single component which is almost like a non-parallelized matching engine. Maybe we should also count logs of public RPC nodes of Ethereum? (Also many txs are not gossiped to the public mempool so these are hard to count)
