Consumer chains should not create a version of the blockchain called Celestia because it would be more difficult to scale than a shared security mechanism.
Rollups are a way to provide an alternative to a more scalable shared security mechanism than in the chain security.
In this week’s episode Anna Rose interviews Mustafa Al-Bassam, co-founder of Celestia. They cover where Celestia as an idea emerged from, how its rollup-centric data availability (DA) network works and what can be expected from their upcoming launch. They also chat about how Celestia aims to empower Sovereign chains - independent rollup chains that use Celestia as the DA and consensus layer - and how this Sovereign chain model compares with the Ethereum rollup architecture.
