According to BlockBeats, Ethereum co-founder Vitalik Buterin said on February 22 that the trade-off between L1 bug risk and L2 bug risk needs to be reconsidered. He believes that if there is a problem with L1, developers can recover in just one day; while problems with L2 may cause users to lose a lot of assets. Therefore, it is worthwhile to add some complex functions to L1 to reduce the burden of L2 code and make L2 relatively simple.
