I am scolded by my boss for being lazy every day, so I should output seriously! Celestia airdropped and took off directly. L2 is too competitive now, and L3 is the chance for future turnaround!
A modular blockchain refers to a blockchain that completely outsources at least one of the four components, namely, the execution layer, settlement layer, consensus layer, and data availability layer, to an external chain, which can minimize the cost of running nodes.
Arranged as follows
1Fuel
Fuel is a UTXO-based modular execution layer that brings globally accessible scale to Ethereum. As a modular execution layer, Fuel can achieve global throughput in a way that monolithic chains cannot, while inheriting the security of Ethereum.
Funding: $81.5 million

2Dymension
Dymension is a sovereign Rollup built on Cosmos that aims to make RollApp development easy through the Dymension Chain (settlement layer), RDK (RollApp Development Kit), and IRC (Inter-Rollup Communication)
Funding: $6.7 million

3Eclipse
Eclipse is a customizable rollup provider compatible with multiple layer 1 blockchains. The platform enables developers to deploy their own rollups powered by Solana OS, using any chain for security or data storage.
Funding: $15 million

4AltLayer
AltLayer is a highly scalable application-specific execution layer system that derives security from the underlying L1/L2. It is designed as a modular and pluggable framework for a multi-chain and multi-VM world.
Funding: $7.2 million

5 India
Initia is used for full-chain Rollup networks, built by fusing novel L1 with application-specific L2 infrastructure systems. Initia has a complete technology stack that implements a set of chain-level mechanisms to align economic interests between users, developers, L2 application chains, and L1.

6Omni Network
Omni Network is the Ethereum interoperability infrastructure, which aims to provide interoperability for Rollup networks such as Op, Arb, zkS and Stark, and become the core infrastructure for all Rollup networks and modular applications on Ethereum, achieving a seamless and secure cross-Rollup user experience.
Funding: $18 million

7Avail
Avail is a modular blockchain focused on data availability, which orders and records blockchain transactions, proving that block data is available without downloading the entire block. This allows it to scale in ways that monolithic blockchains cannot.
Funding: Undisclosed
Twitter: https://twitter.com/AvailProject
Official website: https://availproject.org
8Nautilus Chain
Nautilus Chain is a modular blockchain built on Eclipse that combines the speed of Solana with the decentralization and security of Ethereum to become the fastest EVM chain available, capable of parallel transaction processing.
Funding: Undisclosed

Official website: https://nautchain.xyz
9zkPorter
In zkSync 2.0, L2 state will be divided into 2 aspects, zkRollup with on-chain data availability and zkPorter with off-chain data availability. zkPorter's off-chain DA is maintained by Guardians (zkSync token holders) and has a penalty mechanism.
Funding: $258 million

10StarkEx DAC
StarkEx DAC is the off-chain DA solution of StarkEx, which is an "execution" motor developed for application-specific chains. Starkex can use Ethereum as data accessibility or use data accessibility using committees. This adds great flexibility to Starkex
Funding: $261 million

Advantages of modular blockchain
1. Convenient for launching new blockchains
2. Improved scalability: Modularity allows for expansion without sacrificing security or decentralization.
3. Sovereign: Despite the use of other layers, the new modular blockchain can be as sovereign as Layer 1. This allows the blockchain to respond to hacking attacks and push upgrades without any underlying permission.
