Celestia launches mamo-1, a test network running 128 MB blocks

Celestia/Celestia mainnet

Celestia launched mamo-1, a public testnet producing 128 MB blocks every 6 seconds (~21 MB/s throughput), over 16x mainnet's 8 MB blocks. It runs 21 validators across Amsterdam, Paris, and Warsaw, testing data propagation and block scalability toward 1 GB blocks.

• 128 MB blocks at 6-second intervals deliver 21.33 MB/s permissionless throughput; stress-tests extreme data load.
• Vacuum! protocol with lazy gossiping and Pull-Based Broadcast Tree uses erasure coding for efficient recovery.
• Validators distributed across three European cities; simulates real-world configurations.
• Testnet paves way for future mainnet upgrades toward 1 GB blocks.
