Modular blockchain

Modular blockchains are specialists that only perform one or two functions. The functions that modular blockchains can specialize in are:

  1. Execution
  2. Settlement
  3. Consensus
  4. Data availability

Modular chains don’t sit alone, though. Multiple of them combine to perform all the tasks a monolithic chain does by itself. This combination of chains is what we call a modular stack.

For example, Celestia is a modular blockchain that specializes in providing consensus and data availability for other types of chains.
