The Cancun upgrade was successful, and the gas fee for layer 2 has really dropped significantly, which is great! Will the real layer2 summer come? Currently, op, zksync, starknet, arb and polygon zkvm have been upgraded but have not yet been upgraded. It is true that the improvement of the OP series is more obvious. With such gas, what should we do with competing public chains, sui, aptos, near, and avax?
