On-chain expansion is the only way out. The token of L1 blockchain serves as the execution fee of smart contracts. If the token price is high, users and developers will leave. But if the token price does not rise, investors will leave, which will lead to the loss of users and developers. This is a dilemma. The only solution is to increase the transaction speed on the chain and reduce the single transaction fee. TPS increases with the growth of computing power. This can only be achieved by PoW, which is linked to Moore's Law.
