Celestia mainnet beta launches with data availability sampling

Celestia/Celestia mainnet

Celestia launched Mainnet Beta (codename Lemon Mint) at 14:00 UTC on 31 October 2023, becoming the first modular data availability network four years after the LazyLedger whitepaper. Rollups post their data to Celestia, and light nodes verify data is available by sampling small pieces instead of downloading entire blocks.

• Name: Mainnet Beta, codename Lemon Mint; launched 31 October 2023, 14:00 UTC.
• First modular DA network: separates data availability from execution and settlement layers.
• Light nodes: verify availability via data availability sampling (DAS), downloading only small pieces per block.
• Future roadmap: 1GB blocks for capacity, 1B light nodes for security, 1M deployable rollups.
