Two projects focused on zero-knowledge — the cryptographic concept of proving a statement true without looking at its contents — announced funding rounds this week.

Variant and 1kx headlined a $6 million fundraise for Modulus, a startup using zero-knowledge to “bring AI on-chain.” Stanford University’s Blockchain Builders Fund also participated.

Modulus pitches itself as using zero-knowledge proofs to let AI developers check that their tools are working as intended without sacrificing decentralization. In a blog post announcing the fundraise, the company said a partnership with Worldcoin is in the works. 

Evolution Equity Partners led a $5 million funding round for Boston-based Toposware, a software development firm hoping to woo developers with its “zkEcosystem.”

Polygon co-founder Sandeep Nailwal participated in the funding round and is listed as a member of Toposware’s advisory council alongside Meta’s director of infrastructure and the global general manager of IBM.
