According to @1HowardWu, Aleo has transitioned from R1CS gadget libraries to an opcode-based zero-knowledge virtual machine (ZK VM) architecture, where each operation is mapped to a single circuit. This fundamental change in circuit design improves scalability and programmability for private decentralized applications, a move that could significantly enhance Aleo's position in the privacy coin sector and impact trading interest in ZK technology tokens (Source: Twitter/@1HowardWu, May 27, 2025).
