According to @bolsaverse, AO's decoupled execution architecture is divided into specialized units that enhance trading efficiency. Compute Units (CUs) execute tasks on demand, which can optimize processing speeds for trading algorithms. Messenger Units (MUs) handle inter-process messaging, crucial for maintaining real-time communication between trading components. Scheduler Units (SUs) manage sequencing and Arweave storage, providing robust data management and storage solutions critical for reliable trading operations.
