A quarterly report focused on zero-knowledge (zk) technology indicates that privacy, scaling and identity solutions are major drivers of adoption in the blockchain space.
Validator service provider zkValidator report’s titled ‘The State of ZK’ delves into insights from the zk space, highlighting major and emerging use cases, research, product launches and notable investment rounds.
The key takeaway focuses on use cases of zero-knowledge proofs. The cryptographic method allows one party to verify data or a statement without exposing the information itself. Privacy stands out as the most significant driver of adoption from the industry at 12.90%. Scaling is the second most prominent use case for zk technology with 9.46% interest.
Identity solutions and new zk use cases rank third and fourth, indicating that the blockchain ecosystem is interested in exploring how the zk technology can be applied in the areas of identity management and other novel applications. Zero-knowledge machine learning (zkML) was also identified as the most attractive new use case within the space.
Insights were driven by the company’s work with industry participants, including ZK Hack, zkSummit, rhino.fi, Geometry, and UCL. zkValidator also gleaned data and information working with participants in the production and management of the zkSummit 9 in Lisbon on 4 April.
The launch of Polygon and zkSync’s zkEVMs (Ethereum Virtual Machine) was also highlighted in zkValidator’s report, with key data from the two Ethereum scaling protocols.
Having launched over a month ago, zkSync Era has attracted more daily active users than Polygon’s zkEVM. The report speculates that rumors of a possible zkSync airdrop later in 2023 may be a reason for the gulf in user numbers between the two zkEVMs.

The report also covers the development of new products, including Geometry’s Semacaulk, a new zk set membership protocol that offers gas savings over Merkle-tree constructions, while ensuring proofs can be generated quickly and verified for roughly the same gas cost.
