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.
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.
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.
