The Polygon team presented a solution for scaling Plonky2 based on zero-knowledge (ZK) proofs. According to the developers, it is much faster and more efficient than existing alternatives.

“Plonky2 is a recursive SNARK that is 100x faster than existing alternatives and natively compatible with Ethereum,” the project’s blog says.

Thus, the peculiarity is that Plonky2 can test other SNARK solutions.

The recursive approach is fast, resource-efficient “and can be more decentralized”

“Suppose that we want to prove that a batch of 1,000 transactions are valid. Generating a single proof to verify 1,000 transactions at once would be expensive and time-consuming. Instead, we can take 1,000 machines and generate 1,000 proofs in parallel, one for each transaction. Next, we can take these transaction proofs and recursively aggregate them by generating a layer of recursive proofs, with each one verifying two transaction proofs. We repeat this process until we’re left with a single proof that verifies 1,000 transactions,” the developers explained.

According to them, the recursive approach is fast, resource-efficient “and can be more decentralized.”

Recall that in December, the Polygon project absorbed Mir Protocol startup developing Plonky2 protocol. The transaction amount was $400 million. As a result of the rebranding, Mir Protocol became Polygon Zero.

Developing solutions related to ZK-Rollups

Polygon previously acquired the Hermez Network platform, which also specializes in layer 2 (L2) based on ZK-Rollups. The transaction value was $250 million.

At the same time, the project announced that it will allocate $1 billion for the development of solutions related to ZK-Rollups.

In November, the team presented a solution for scaling Ethereum based on ZK-Rollups. Moreover, they released its central component – a virtual machine using the ZK-Starks protocol as a basic proof system. The solution name is Polygon Miden. This is an open-source project. Bobbin Threadbare, the creator of the Winterfell cryptographic library, which Novi from Facebook is using, led the development.
