Polygon has released its second-level blockchain, built on zero-knowledge proof technology
In fact, Polygon became the second company in four days to make the so-called “zkEVM” available to the general public.
Second-layer blockchains, also known as rollups, collect and compress user transactions before adding them to the Ethereum blockchain. This significantly reduces the cost of each transaction and increases the number of transactions Ethereum can process.
But the zk (zero-knowledge) technology itself is very interesting; in short, it allows you to confirm smart contracts without disclosing unnecessary data, which directly affects user privacy.
Polygon zkEVM remains in beta and the company stresses that it should be used with caution - something that will change in the coming months, according to company co-founder Mihailo Bjelic.
At the moment, we are seeing a fairly noticeable narrative from companies on the second-level network.
Matter Labs, Polygon and other companies are rushing to present their second-level subgrids; this niche is now dominated by the well-known rollups Arbitrum and Optimism. These two leaders account for 88% of all crypto assets placed on rollups (according to L2BEAT).
