celestia is a blockchain designed to be used purely by rollups in theory it should allow to launch rollups with very cheap (and secure) fees eg base could be deployed as an OP Stack rollup but post data to celestia instead of ethereum closes competitors are EigenDA / Polygon Avail / ETH after 4844 (none is live yet)

What's the most successful roll up using Celestia? Do people consider Celestia an Ethereum competitor? Is Celestia POS? How decentralized / secure? Is it EVM or something else?

good questions 1. none, celestia launched a month ago but i haven't heard of anything deployed on it yet 2. its confusing i guess it is an eth competitor but celestia people really like eth and pretend like its not? 3. no evm, no smart contracts, just blob data for rollups.

There's some designs where rollups benefit from both, like using celestia (or other DA layers) for intermediate security (very fast checkpoints/confirmations) and Ethereum for ultra hard security (less frequent checkpoints, failure mode governance override, etc).

Though the spec for danksharding is competitive with what celestia offers, so it's hard to tell if there would be long term symbiotic opportunity.

On the other hand, could use something like eigenlayer to loan Ethereum security and bolt on computation onto a Celestia rollup, and get a mostly competitive rollup offering with anything Ethereum would have without actually using the Ethereum L1.
