A criticism of the setup is that at this time’s rollup sequencers are usually run by “centralized” entities, and thus signify single factors of failure, potential vectors for transaction censorship, or probably a choke level if authorities ever selected to close all of it down. Coinbase, for instance, runs the sequencer for its new Base blockchain, a job that might produce an estimated $30 million of web income yearly, primarily based on estimates by the evaluation agency FundStrat.
