CoinMeta data: Robinhood Chain is evaluating a new payment transaction sorting system that allows users to pay a fee to prioritize the processing of certain transactions. This technology was developed by Arbitrum, and Robinhood Chain is a popular layer-2 blockchain tailored specifically for tokenized real financial assets. Currently, Robinhood Chain uses a first-come, first-served transaction sorting policy. Since its Ethereum-compatible network was launched in July, its popularity has risen rapidly, and it has now entered the top ten in terms of total locked value. The traditional brokerage business of Robinhood is combined with a 24/7 on-chain token stock distribution model, and it has long been profitable through "order flow payments." The priority of paid transactions works differently on the blockchain, as it can speed up transaction processing and help professional companies compete for rapidly changing trading opportunities.
