This article discusses the potential and applications of Zero-Knowledge Proof (ZKP) technology in the blockchain domain, emphasizing ZKP's potential uses beyond Layer 2 scalability solutions. It mentions projects such as Polyhedra, Succinct, and RISC Zero, which are exploring large-scale applications of ZK technology and addressing challenges like developing universal technologies, building distributed proof systems, and optimizing computational consumption. The article specifically highlights Polyhedra's zkBridge cross-chain asset transfer scheme, and how ZK technology facilitates cross-chain communication and asset transfers, enhancing security and efficiency. It argues that the potential of ZK technology is far from fully realized and that its maturity in various vertical niches will significantly impact the industry in the future.
