1/10 @celestia isn’t trying to become another smart contract chain.

It’s focused on making the data layer radically simpler, letting others build on top. https://t.co/uHn3SX2RiN

2/10 #Celestia separates consensus from execution.

It doesn't run smart contracts.

Instead, rollups post their data ("blobs") to Celestia, and the network ensures they're available and ordered.

Execution happens elsewhere. Celestia just handles the data. https://t.co/428eM9fXZ7

The pattern? Fast-moving apps with unique data needs.

7/10 Celestia isn't trying to replace Ethereum or Solana.
It's a neutral DA layer. A base infrastructure others build on.
In a modular world, Celestia can be the DA layer that powers hundreds of rollups across chains.

8/10 The latest upgrade, Lotus, is now live on Arabica testnet. It brings native support for Hyperlane, enabling cross-chain TIA transfers, and reduces inflation by 33%. Mocha and Mainnet rollouts are expected in Q3.

5/10 It works via #DAS (data availability sampling).

Nodes sample small chunks of each block. If enough samples are valid, the block is provably available, without downloading the whole thing.

Combine that with Namespaced Merkle Trees, and rollups only see their own data.

6/10 More than a dozen modular apps already rely on Celestia.

@hibachi_xyz - privacy-first perps 
@kamigotchiworld - onchain game 
@townsxyz: decentralized social 
@plumenetwork -  RWA rollup 
@WINRProtocol - DeFi casino

3/10 That makes it radically simpler and cheaper.

By moving #DA to a dedicated base layer, Celestia reduces publishing costs by ~95%.

This makes fully onchain games, rich media apps, and state-heavy simulations actually viable.

4/10 Already live and in use.

While competitors like @eigen_da and @AvailProject are still pre-mainnet, Celestia powers real deployments today:

• @arbitrum 
• @ORBIT 
• @Optimism
• @dymension
• @RollkitDev
• @LightLinkChain

Celestia's focus on simplifying the data layer and enabling others to build on top is a strategic move towards more efficient and scalable blockchain infrastructure. This separation of concerns could lead to a more modular and interoperable ecosystem.
