Example: T6 is totaling balances of account x (£100), account y (£50), and account z (£25). Meantime, • T5 has transferred £10 from balx to balz, so T6 now has wrong result (£10 too high). Inconsistent Analysis Problem Problem avoided by preventing T6 from reading balx and balz until after T5 completed updates.
