In the blockchain world, transaction ordering has always been a key issue. Traditional aggregation architectures use a single sequencer for transaction ordering, and this centralized approach has many drawbacks. It not only faces the risk of single points of failure but can also lead to transaction censorship and unfair maximum extractable value (MEV) extraction.

To address these challenges, AltLayer has launched the innovative SQUAD system. SQUAD adopts a distributed approach, consisting of multiple re-extraction operators forming a decentralized 'parliament' that collectively decides the order of transactions. This design significantly enhances the reliability and fairness of the system.

The advantage of SQUAD lies in its decentralization. Even if individual operators encounter issues, the entire system can still maintain stable operation, effectively reducing the risk of system crashes. More importantly, SQUAD significantly decreases the possibility of malicious MEV extraction through decentralized decision-making, enhancing the fairness and censorship resistance of layer 2 networks (L2).

In SQUAD mode, each transaction receives equal processing opportunities, no longer subject to the decisions of a single centralized entity. This innovative approach not only enhances the overall efficiency of the blockchain network but also paves the way for establishing a more fair and transparent trading environment.

The emergence of SQUAD marks a significant step forward in the decentralization of blockchain technology. It not only addresses some of the core issues currently facing blockchain but also provides new ideas for the future development of technology. As this technology continues to evolve and be applied, we have reason to expect that the blockchain ecosystem will become healthier, more efficient, and fairer.
