Celestia data availability sampling and light nodes in the Celenium explorer

Explains how Celestia's DAS lets low-spec light nodes sample erasure coded blobs to get probabilistic availability guarantees, with securely sampled blob size growing with light node count. Celenium v1.18 embeds a browser light node, with wallets as the next step.

Key claims
Securely sampled blob size increases as the number of light nodes grows
One honest full node suffices to provide fraud proofs
Celenium v1.18 runs a Celestia light node in the browser
This is really cool! 🤯 @CelestiaOrg ensures DA through a unique "Data Availability Sampling" mechanism performed by low spec light nodes on erasure coded data blobs (adding redundancy to allow for reconstruction even if part is missing). The light nodes collectively sample small chunks of the overall data blob to arrive at probabilistic guarantees of the full data being available. As long as there is at least one honest full node to provide a fraud proof if necessary, light nodes can operate under the same security guarantees. What's really cool though, is that the blob size that can be securely sampled increases as the number of light nodes in the network grows. @celenium_io v1.18 embeds the light node in the block explorer and runs it in the browser. That's a first step in embedding light nodes in the surrounding infrastructure and tooling. Up next? Wallets. Soon everyone will be running light nodes under the hood, probably without even knowing, and unlocking limitless scale for Celestia's DA. Big blocks. Fully verifiable. 🧱✨
