ZKRollup-as-a-Service: Opside's L3 Rollup Chain, Environments, Advantages, and Support for Devs

Opside is a cutting-edge zkRollup-as-a-Service (ZK-RaaS) platform that enhances the performance, security, and scalability of decentralized applications (dApps) with its three-layered architecture and Zero-Knowledge (ZK) technology.

Developers can build dApps on Opside's L3 rollup chain to reap:

1. a high-throughput,
2. low-fee environment
3. without infrastructure maintenance.

Existing EVM-compatible applications can be easily migrated to Opside L3, and developers familiar with Ethereum or other EVM-compatible L1 platforms can utilize our existing resources.

Decentralized ZK-RaaS

Opside Layer3, aka the Rollup Layer, is a scaling solution that executes transactions off-chain, so it doesn’t have to compete for precious Execution Layer block space.

After a transaction is executed, a batch of the transaction data or proof of execution is sent to the Execution Layer, where it is validated and finalized.

Therefore, the Rollup scaling solution is protected by the same security measures as the Execution layer, which acts as the source of truth for the Rollups.

Opside L3 uses several zkEVM that can efficiently verify the correctness of program execution to cater to the different requirements of dapps.

To be specific, Opside Layer3 will be composed of the following types of ZK-Rollup environments:

1. General-Use Environment

The general-use environment enables ordinary users and developers to interact with Opside Layer3. To ensure a safe, stable, and reliable zkEVM to run the general-use rollup, Opside proceeds along two aspects:

a. Continue to follow up on and study the open-source zkEVM projects currently on the market, including Polygon Hermez, Scroll, Taiko, etc. Opside will selectively integrate these projects according to each project's features and specific conditions (like open source degree and code stability).

b. Opside also has a strong relationship with ZKWasm, an under-development ZKWASM-based scaling framework designed to be friendly to apps from the traditional Webassembly community, including web, gaming, and social applications.

2. App-Specific Environment

Regarding App-specific Rollups, Opside will provide independent execution environments for projects in need through specialized configuration and optimization to meet the various needs of their Apps in terms of performance and economic models.

Since valid zero-knowledge proofs still need to be submitted to L2, these customized changes will not affect the security of this type of rollup. Such Rollups will also be registered in L2 Rollup Slots and enjoy additional features, including cross-rollup communication, precompiled ZKP verification contracts, etc.

Opside also plans to design and implement application-specific circuits for these app-specific rollups. The team will modify rollups' underlying circuits and operation codes to make them more suitable for the applications' operation logic. This modification trades some common but unnecessary operations for less runtime overhead.

Other Advantages of Using OPSide’s Rollup Layer

1. ZK-RaaS - ZK-Rollup has the advantages that OpStack does not have: more secure, more trustless, and faster withdrawals

2. Hardware support - Developers do not need to bear any hardware costs

3. 0 gas fee - Developers can adjust/reduce the gas token and gas fee, even to 0. Thus, users do not need to pay any fees

4. Fully on-chain - All project data, including games, financial derivatives, and social networks, can be fully on-chain

5. EVM compatible - We will introduce multiple zkEVM SDKs, including Polygon zkEVM, Scroll, zkSync, and StarkNet, among others

6. Sovereignty - Developers have sovereignty over ZK-Rollup and can customize the rollup economic model, such as the 0 gas fee mentioned above

7. Cross-rollup communication - Layer 3 ZK-Rollups will share the same interface specification and data results, realizing native cross-rollup communication

8. More decentralized - Opside adopts ETH2.0 PoS consensus and will have more than 100k validators.

Support

Developers seeking support while deploying on the Opside L3 Testnet can contact us via the Opside Discord server.

Building on app-specific zkRollups is similar to the general-use Rollup, with the only difference being:

1. The unique RPC endpoints and
2. Contract information
