Announcing mamo-1: Celestia’s 128MB block testnet

Today we're introducing mamo-1, a public testnet that pushes Celestia to new extremes. Built for applications at the frontier, mamo-1 delivers 128MB blocks and 21.33MB/s of permissionless throughput—offering the infrastructure needed to test real-world, high-throughput applications and prepare for the road to 1GB blocks. That’s over 16x the throughput of Celestia mainnet today, which currently supports 8MB blocks. mamo-1 is now live. It’s a high-performance testnet specifically designed to: With 128MB blocks produced every 6 seconds, mamo-1 enables data throughput of 21.33MB/s—a seismic leap from Celestia’s earlier testnets and a major milestone in the modular blockchain scalability roadmap. 👉 Track live activity on the block explorer 👉 Start testing on mamo-1 with our how-to guide The launch of mamo-1 follows the successful Mammoth Mini prototype devnet, which showcased 27MB/s under experimental conditions. Now, mamo-1 provides a similar level of throughput but in a more production-
