ZK Stack is an open-source solution that allows you to create Hyperchains in the zkSync ecosystem. Unlike other solutions, Hyperchains can be both Layer 2 and Layer 3.

Key Benefits of zkSync Hyperchains

The zkSync Hyperchains have the following advantages:

• Security: The interactions between fractal hyperchains in L3 zkSync will be through native bridges, which will enhance security.

• Performance: By implementing hyperchain architecture and achieving hyper-scalability, L3 performance is improving.

• Cost: As a result of implementing data availability solutions, data fees are being reduced significantly.

• Ease of Use: zkSync involves significant enhancements to the SDK, including the implementation of code-free solutions.

• Compilability: The compiler supports Solidity and any other modern programming language, making application development more accessible.

In addition, ZK Stack solutions natively support Account Abstraction.

Other ZK Stack Features

ZK Stack also offers developers three different data access options: ZK Rollups, zkPorter, and Validium, which increases customization options to meet developers' needs. Customization concerns not only data accessibility levels but also transaction sequencing.

The product is still at a very early stage, and only one project works as a hyperchain. That project is GRVT, a hybrid on-chain exchange.

Conclusion

ZK Stack is undoubtedly the most interesting solution compared to its competitors. Hyperchains can be adapted to almost any need, thanks to customization at different levels and the integration of the most advanced blockchain technologies. However, it needs to be made clear how successful they will be in scaling up in practice. They have a lot of work to do in the B2B segment, as their competitors are already actively plugging new chains into their ecosystems.

Will ZK Stack and Hyperchains become worthy competitors to OP Stack, Arbitrum Orbit, and Polygon CDK? Time will tell.

Polygon CDK is an open-source solution with a modular environment at its core. Developers can use CDK to run ZK-based Ethereum L2 networks or to convert existing L1 networks to L2. This is a continuation of the old Supernet concept.

Polygon CDK Advantages

• Secure and near-instant interoperability with all other Polygon networks, enabled by LXLY Bridge;

• Automatic, seamless access to the Polygon ecosystem's shared liquidity;

• Fast access to all Ethereum liquidity;

• Simplified proof-of-stake system for transactions;

• ZK technologies for better security;

• Modularity and customization, with the feature of creating private blockchains;

• Data integrity and resilience, namely due to the fact that networks built with CDK will have a dedicated Data Availability Committee (DAC) that ensures reliable access to off-chain data.

If you are building a DeFi application for millions of active users, you can use Polygon CDK to build an independent Layer 2 blockchain. It will meet the specific requirements of your project, such as TPS, custom security parameters, gas fees, and token model.

Comparison With Competitors

What differentiates it from Arbitrum Orbit, ZK Stack and OP Stack is that with Polygon CDK, you can build ZK-Rollups instead of Optimistic Rollups. As you may already know, they have a number of advantages, which we have previously covered:

• Faster transactions

• Algorithmic transaction confirmation

• High privacy

Many projects are already being built on Polygon CDK. For example, Manta Network has switched from OP Stack to Polygon CDK. Other notable blockchains include Canto, Astar, Immutable, IDEX, and Palm Network.

The Future of Polygon CDK

Polygon is not stopping at the implementation of CDK; the ecosystem will have a full-fledged transition to Polygon 2.0, where we will see the use of the new POL token across the entire ecosystem, as well as more decentralization and further transfer of governance to the community.

Additionally, yesterday it was announced that Polygon Village has launched a $90M fund for the development of the ecosystem.

Compared to the competitors, Polygon CDK looks like a more secure solution due to its adoption of ZK technologies. However, in terms of partnerships, they have yet to catch up with Optimism Collective. Out of the three solutions, which one do you think will come out on top? Only time will tell, but it's exciting to see what the future holds!
