Zero-Knowledge Proofs (ZK) are emerging as a pivotal solution to the challenges faced by public blockchains, such as network congestion, high transaction costs, and privacy concerns. ZK-Rollups, a specific application of this technology, offer instant transaction finality and enhanced security through cryptographic proofs, surpassing the capabilities of Optimistic Rollups. This innovation is driving global adoption and reshaping digital sovereignty, while also intensifying competition in computational power. Despite the potential of ZK technology, it faces hurdles including high development costs and the risk of centralizing proof generation. These challenges must be addressed to fully realize the benefits of ZK in enhancing blockchain performance and trust.
