Celestia has unveiled Fibre, a revolutionary data availability protocol that promises to transform the blockchain landscape. Launched on January 13, 2026, this innovative technology is set to redefine how applications leverage blockchain capabilities. The report highlights positive developments indicating that the adoption of such protocols could significantly enhance scalability and efficiency in blockchain networks.
Impressive Capacity of Fibre
Fibre boasts an impressive capacity of 1 terabit per second of blockspace, facilitated by approximately 500 validator nodes. This remarkable throughput represents a significant departure from traditional blockchain designs, which often prioritize throughput as the main constraint.
Engineering for High Bandwidth and Low Latency
The protocol is specifically engineered to cater to applications that demand exceptionally high bandwidth and minimal latency. By enabling entire categories of markets and applications to function entirely on-chain, Fibre opens up new possibilities for developers and businesses looking to harness the full potential of blockchain technology.
On January 13, 2026, Ethereum co-founder Vitalik Buterin announced a solution to the blockchain trilemma, which contrasts with Celestia's recent unveiling of the Fibre protocol. For more details, see the full story here.
