Celestia just launched Fibre, claiming a staggering 1 terabit per second of blockspace—a figure that could reshape the entire scalability landscape in 2026.

Let that sink in. We're talking about throughput that would dwarf most current Layer 1 solutions. If these numbers hold up, it's not just an incremental upgrade; it's a potential game-changer for how rollups and modular blockchains operate at scale.

The modular blockchain movement has been building momentum, and moves like this are exactly why. Whether Fibre lives up to the hype remains to be seen, but the ambition alone signals where the industry's head is at right now—pushing boundaries on what's technically possible.
