Celestia: A Modular Stack for Data Accessibility

Celestia is within this modular stack. It does consensus and data availability together in one protocol essentially. The beauty of data availability sampling is that a a light client equivalent amount of resources We call it a light node Can sample that block And it could be like your smartphone And it could verify for itself that the data is available. But to get those kind of guarantees on a normal blockchain You have to run like a very beefy machine like if it's a slana.
