A three-layer architecture for high-throughput web3 applications.
Architecture
Layer3: Rollup as a Service
- Rollup SDKs for general-purpose & application-specific rollups
- PoVP: a native decentralized consensus for Rollups
Layer 2: Opside chain with native rollup and hybrid consensus of PoS + PoW
- Rollup slots: unified smart contract entry for zk-rollups
- Cross-rollup Communication: an intuitive and practical ZK-Rollup interworking scheme
- Precompiled contracts: accelerate the verification of zk proofs
Layer 1: Multi-chain bridges
- Liquidity bridge: fast bridges between any two layers
- Further: zk-bridge, a trustless secure bridge
Advantages
High Security
With zkBridge and provable PoS, Opside chain inherits the security of Layer 1. Layer 2 verifies all zk proofs of rollups in layer 3, sharing the same consensus layer. As a tighter whole, Opside 3-layer architecture is more secure and decentralized.
Infinite Scalability
The entire system can be scaled infinitely by adding an arbitrary number of rollups to layer 3. Users may use pre-deployed general-purpose rollups or their own application-specific rollups, with a native cross-rollup communication mechanism.
Asset Variety
By building different types of bridge to multi blockchains, layer 2 and 3 can accept a variety of assets from layer 1. Liquidity Bridge is faster and cheaper. ZK bridge is more secure for large amount of asset transfers.
