Why are Layer 2 networks shifting toward decentralized sequencers?

Many optimistic rollups still rely on a single sequencer to organize transactions before they are finalized on Ethereum. Although this model has worked well, it leaves the network exposed to a single point of failure. If that sequencer experiences downtime, transaction processing across the network can be interrupted.
Projects like METIS are changing this by adopting decentralized sequencer pools that spread block production across multiple independent operators. This approach strengthens security, improves censorship resistance, and makes the network far more resilient.
As Layer 2 infrastructure evolves, maintaining low fees and reliable performance remains essential. Users should be able to enjoy fast and seamless transactions without worrying about the technology operating in the background. On the TON blockchain, STONfi supports this experience with efficient spot liquidity, making asset swaps simple and smooth.
