zkSync Era Introduces Hyperchains to Redefine Interoperability and Speed in Blockchain

Ethereum scaling system zkSync Era has introduced its own version of Optimism’s Superchain concept, called ZK Stack. ZK Stack is a modular framework comprising a series of ZK-powered custom blockchains known as Hyperchains. These Hyperchains will function as an additional layer on top of the existing layer-2 protocol. They will be composable and interoperable, enabling near-instantaneous transfers of liquidity and flash loans between protocols within the system, a feature not available on L1 blockchains.

Similar to Optimism’s Superchain network, which introduced Coinbase’s BASE as the initial addition, ZK Stack shares some similarities. Alex Gluchowski, co-founder and CEO of zkSync, emphasized that the system eliminates the need for insecure and cumbersome token bridges, which have often been exploited in major cryptocurrency hacks.

Gluchowski stated, “We have the ZK Stack now available for people to start building, and we already have the first products we’re working with to build it, and this will be live on the testnet definitely by the end of the year.”

Although Gluchowski expects more than 95% of DApps to continue operating on L2 directly, Hyperchains will likely cater to projects with specific requirements concerning privacy, speed, and data availability. Potential users include games, social networks, low-latency exchanges, and banks.

Since its relatively modest launch, zkSync Era has experienced significant growth, with a total value locked of nearly $620 million. Currently, it processes approximately 20.8 million transactions per month at a rate of around 8 transactions per second, peaking at 12 TPS.

Gluchowski likened the ZK Stack to the framework of the internet, emphasizing its limitless potential for expansion. He noted, “You can always add more servers, more cables, more connections and grow it from 1000 servers to 1 million servers to 1 billion servers. Blockchains today are not having this property.”

To achieve scalability, ZK Stack utilizes recursive scaling, where transactions are batched into a ZK proof, and a series of these ZK proofs are then batched into a single proof, achieving greater compression. This enables the system to theoretically scale according to any demand. Gluchowski explained, “We can still combine multiple proofs from multiple protocols together and paste them together recursively. Every once in a while, we will just publish one single proof on Ethereum which trustlessly incorporates the proofs of all these chains.”

The code for ZK Stack is freely available and open-source under the MIT/Apache license. zkSync revealed that a few significant partners have already committed to testing the system, although no further details were provided.

While ZK Stack can theoretically connect with other ZK roll-ups such as Polygon’s zkEVM, ConsenSys’ Linea, or StarkNet, Gluchowski indicated that this possibility is unlikely. Therefore, the ZK Stack is not expected to address the interoperability challenge with ZK roll-ups in the near future.
