Modular Blockchain
An architecture that separates a blockchain's functions — execution, settlement, consensus, data availability — across distinct specialized layers.
A "monolithic" L1 like Solana or Sui does everything itself: execution, settlement, consensus, data availability. A modular stack splits the responsibilities: execution to rollups, settlement to Ethereum, DA to Celestia or EigenDA, consensus to whichever layer needs it.
The bet is that specialization scales further than a single chain ever can. The cost is the operational complexity of coordinating multiple layers — and the trust assumptions across them.
