ChainCatcher news, according to official sources, Polygon Labs has announced the acquisition of the ZK engineering startup Toposware, with the specific acquisition amount not yet disclosed.It is reported that the Toposware team is integrating with the existing Polygon ZK development team to further advance Hong Kong technology, including AggLayer, Polygon CDK, Polygon zkEVM, and ultimately upgrading Polygon PoS (pending community approval) to ZK validium.

ChainCatcher news, Polygon Labs announced a partnership with Toposware to develop a new Type 1 zkEVM prover.It is reported that the Type 1 zkEVM prover allows any network compatible with the Ethereum EVM standard to become a Layer 2 network supported by zero-knowledge proofs and connect to the broader Polygon network ecosystem. The Type 1 zkEVM prover is even capable of generating these ZK proofs for Ethereum mainnet blocks, with an average cost of 0.002-0.003 USD per transaction. The Type 1 prover is open source and available on GitHub, licensed under MIT and Apache 2.0.

ChainCatcher news, zero-knowledge encryption technology company Toposware (Topos) announced the completion of a $5 million extended seed round financing, with participation from Evolution Equity Partners, Triatomic Capital, K2 Access Fund, and Polygon co-founder Sandeep Nailwal.According to the RootData page, Topos is an interoperability protocol that utilizes zero-knowledge proofs and reliable broadcasting, allowing various public and private blockchains to communicate with each other. Zero-knowledge proofs enable blockchains to prove the validity of their state transitions without compromising private internal information, such as account addresses and account balances. Topos previously completed a financing round of 750 million yen in 2021.
