Celestia Mainnet Goes Live
Celestia, a modular data availability network, is now live on mainnet beta. The deployment comes four years after the release of its original whitepaper. Keplr, Leap, Ledger, and Mystic Metamask Snaps are compatible with the network. Users can use Celenium, Mintscan, and Modular Cloud block explorers for tracking Celestia transactions. Users can also operate a Celestia Light Node, which plays a vital role in gossiping information and helping ensure data accessibility. Developers can use Caldera, AltLayer, and Vistara RaaS providers to deploy rollups with Celestia serving as the data availability layer. At the time of writing, TIA, Celestia's native token, is trading at $2.42.
Vitalik Outlines Types Of L2s
Vitalik Buterin published a blog post outlining the diversification in the Layer 2 ecosystem. He notes trends in varying types of L2s, including L1 projects transitioning to L2, centralized projects aiming for enhanced security, and non-financial applications striving for a balance between security and decentralization. The blog outlines Rollups and Validiums. Rollups validate computations through either fraud proofs or ZKPs and keep data on L1. Validiums use ZKPs but store data externally. Vitalik introduces the term disconnected systems, which refers to trusting a small set of entities not to mishandle funds. He also underscores two facets of connection to Ethereum: the security of withdrawing to Ethereum and the security of reading Ethereum.
Unibot Suffers $640k Exploit
Unibot, a popular Telegram-based trading tool, suffered an exploit resulting in a loss of over $640k. Uniswap founder Hayden Adams criticized the tool for its poor private key storage method and for trading through unverified routers. A vulnerability allowed an attacker to make an arbitrary call to drain tokens that were approved for the contract. Unibot allowed users to swap assets without having to leave the Telegram app.
