I think the essence of inscriptions and its biggest application scenario is to put non-ledger data on-chain, so the speed of one block every 10 minutes is completely sufficient. In art trading, who cares about 10 minutes versus a millisecond? If a transaction of 10 billion dollars is completed in a flash within a second, wouldn't it feel a bit unsettling? If there is also some on-chain privacy, then for such large countries, transactions between central banks and institutions can completely use the BTC chain. Canton @CantonNetwork's blocks are also one every ten minutes, and in the tests of bill settlements among 13 central banks organized by BIS and the World Bank, it also fully meets the requirements.
