Celestia $TIA umped 16% today to around $0.68, its highest level of 2026 and the biggest gain among CoinDesk 100 members. Celestia is a modular data availability network, which means it focuses on one job: storing and publishing transaction data so other blockchains do not have to. I find it a good example of specialization in crypto. The move came while the largest coins stayed mostly flat, so I am treating it as a single token story and watching volume before drawing conclusions.
