A look at 35 noteworthy modular protocols

What exactly does modular currency mean? Why are there hundreds of new “modular” protocols on the market now?

Modularization has been attracting much attention since this year, and the launch of Celestia and TIAToken last year further contributed to this trend. Modularity is not just a buzzword, its importance lies in solving the dilemma of blockchain scaling by migrating specific components into specialized infrastructure. The construction of this infrastructure allows the blockchain system to operate more flexibly and efficiently, while also helping to improve the scalability and stability of the entire ecosystem. The emergence of modular infrastructure has brought more possibilities and development space to the blockchain industry, and promoted technological progress and innovation. It is foreseeable that modularization will continue to play an important role in the blockchain field

It needs to be clear that modularity is not a temporary move, and it will not gradually disappear as we gradually enter the bull market. Rather, modularity is a core design principle of blockchain and may play an increasingly important role in the future of cryptocurrencies. Therefore, it is crucial to understand the concept of modularity and which protocols you should focus on.

1. What is modularity?

What does modularity mean in blockchain architecture? You may have heard of this concept, but as a quick refresher, the image below illustrates it nicely:

Monolithic vs. Modular Blockchain Architecture comparison

At its core, blockchain has four roles, or consists of four layers:

Execution layer - processes transactions for dapps on the chain and executes smart contracts. This is where calculations take place and account balances are updated.

Settlement Layer - determines the overall status of the blockchain. The status of the completed on-chain transaction is determined.

Consensus Layer - Orders transactions by ensuring nodes agree on the state of the chain.

Data availability layer - ensures that data (transactions, blocks, etc.) are publicly available to all network participants, that is, accessible to everyone.

Monolithic chains like Ethereum mainnet, Solana, Avalanche, Sui, Sei, etc. are all monolithic chains that handle all these components. Optimistic rollups like Arbitrum and Optimism are part of the modular stack because they serve as execution environments that move data availability, settlement, and consensus to the Ethereum mainnet.

Rollups like Manta are even more modular because it is an execution environment that uses Celestia for cheap data availability and leverages the Ethereum mainnet for consensus and settlement.

There are many examples and many different combinations of modular infrastructure. By understanding the following, you'll be on the right track on your modular journey.
