Rollup Interoperability Protocol: The New Holy Grail in Modular Public Chain Primitives

Written by: NingNing

Entering 2024, the modular public chain infrastructure is accelerating and improving. Dapp Rollup new paradigm products built on these infrastructures (Perp DEX, Web3 game Infra, anti-OEV oracles, NFT trading platforms) have emerged one after another.

And the Dapp Rollup new paradigm Perp DEX Aevo, which is about to start trading farming, will be the first shot of the new paradigm Dapp challenging the old paradigm Dapp (GMX built based on universal Rollup, etc.), and then start the sustainability of Flip in this round of bull marketcontract CEX ceiling Bybit process.

The superpower of Dapp Rollups comes from their modular structure.

We know that a modular public chain is achieved by combining a singleBlockchainIt is decoupled into four stacks including consensus layer, data availability (DA) layer, settlement layer, and execution layer, and then introduces DAS (data availability sampling) technology and the architectural design of light nodes responsible for consensus verification, achieving decentralization,SafetyThe unity of performance and scalability.

At present, the modular public chain stack infrastructure is booming and prosperous.

Mainstream projects in the data availability (DA) layer include Ethereum, Celesita DA that uses optimistic-fraud proof to ensure data availability, Avail DA that uses KZG commitment-validity proof to ensure data availability, Near DA, and Restaking verification set + KZG commitment validity. Verify EigenDA that guarantees data availability (not yet online);

Mainstream projects in the settlement layer include Dymension, which supports modular Rollup to share AMM liquidity and interoperability, and Cevmos, which connects modular Rollup and EVM-compatible inter-chain liquidity;

Mainstream projects in the execution layer are divided into two categories: native modular execution layers such as Fuel and Eclipse, and SDKs provided by general Rollup such as Op Stack, Arbitrum Orbit, Polygon CDK, and Zk Stack.

In the encryption industry, there has always been a phenomenon of supply leading demand or even supply creating demand. At a time when the new paradigm of Dapp Rollup has just emerged, there are already many Raas (Rollup as a Service) service providers that use the above modular stack to help Dapp developers build Rollup. The mainstream projects include Altlayer, Gelato, Conduit, Caldera, etc.

Among them, Conduit is the Raas service provider for high-performance Dapp Rollup required by Perp DEX such as Aevo and Lyra. Caldera mainly builds Dapp Rollup infra for Web3 games, such as Loot Chain, HYTOPIA, etc.

With the middle layer also mature, the last piece of the puzzle of the modular public chain infrastructure layer - Dapp Rollup interoperabilityXiaobai NavigationThe protocol has become a new design space that stimulates competition between current encryption VC and encryption VC, and between developers.

Generally speaking, interoperability protocols in the encryption industry have a common meta-problem, which is how two different individuals/entities can reach consensus/consistency with trust.

BlockchainIt is the solution to the meta-problem AliceBob, the cross-chain bridge is the solution to the meta-problem Chain A ChainB, and Rollup is L1 L2 The solution to this meta-problem.

To achieve cross-chain (including L1 and L2) Interoperability has the following 6 classic paradigms:

• Hash timelock atomic swap

• MPC multi-signature relay layer

• Tendermint SDK relay layer

• Zk proof + light node

• Light node + oracle

• Rolllup relay layer

In the above 6 classic paradigm architecture designs, all need to beSafetyThere is a trade-off between security, finality, and capital efficiency.

Among them, the cross-chain bridge with minimum trust assumption adopts L2Rolllup relay layer L2 architecture cross-chain bridge, such as Orbiter, Across, etc.

This architecture is also what Vitalik has always recommended. However, this method was not widely adopted before. The reason was because of Ethereum’sSafetyBlock service fees (alias for Gas) are high and finality is long (12 minutes). Now, after the modular public chain infrastructure is improved, the above two problems can be easily solved.

The Rollup interop protocols currently on my watch list are:

Ultra-modular public chain KIRA Network

KIRA Network proposed new primitives of "super modularity" and "finality". The MF layer in its network architecture uses the Staking-Slash game mechanism + block header verification mechanism to replicate the status of all chains and rollups, and reduces the network complexity of the NN of the interoperability protocol to the network complexity of NKIRA.

Interwoven Rollup Interoperability Protocol Initia

Initia has proposed a new primitive for Interwoven Rollup, but has not released documentation yet.

Extend IBC interoperability to Polymer across the chain

Polymer itself is an Ethereum Rollup, which uses IBC technology to achieve interoperability between different Rollups. It leverages the OP Stack as the settlement layer, the Cosmos SDK for native IBC interoperability, and EigenDA to provide scalable proof of data availability.

Imagine that at the peak of this bull market cycle, there will be 1 billion active users on millions of Dapp Rolllup new paradigm products. Interoperability between Dapp Rolllups will become a market imperative. That's why the Rollup interoperability protocol, which uses a modular stack to build the Rollup relay layer, has become the new holy grail of modular primitives.
