Celestia: A technical overview

Quick Take

  • Celestia is a data availability layer that aims to solve one of the fundamental constraints of blockchain scaling — data availability
  • By abstracting consensus from state execution, Celestia promises a more performant network than blockchains that lump the two together
  • Celestia utilizes erasure codes to create data availability proofs that guarantee, with high probability, that all that data was posted on-chain
  • Celestia nodes can scale better because they are no longer required to store and verify every transaction in the block
  • Aside from improving scalability, Celestia also provides application interoperability
