Modular blockchain Celestia has launched its new testnet, mamo-1, aimed at enhancing scalability ahead of future mainnet upgrades. The testnet can handle up to 128MB blocks every six seconds, which is over 16 times the capacity of the current mainnet. It is designed to simulate real-world conditions for applications that need to process large volumes of data.
Building on the previous smaller prototype called Mammoth Mini, which achieved a throughput of 27MB/s during lab testing, mamo-1 takes it further. Unlike its predecessor, mamo-1 is open to the public and integrates with Celestia’s complete data availability layer, offering support for light nodes and data availability sampling. To ensure a realistic network experience, the testnet is backed by 21 validators based in Amsterdam, Paris, and Warsaw, reflecting the dynamics of real-world usage.
This upgrade is partially driven by introducing a new data transfer protocol called Vacuum!, which optimizes data movement across the network. Instead of overwhelming the network with excessive data, nodes only transmit it to peers who specifically request it. This approach significantly minimizes unnecessary traffic, enhancing the system’s speed and efficiency.
Celestia views this new technology as a crucial step toward achieving its goal of handling 1GB blocks. Since launching its mainnet in October 2023, over 20 rollups, including Eclipse, Movement Labs, and Dymension, have already deployed on the network. Nevertheless, competition from rival data availability networks such as EigenDA and Avail could challenge Celestia’s lead in the space.
In a broader context, Ethereum is also making strides in scalability with the upcoming launch of a new testnet called Hoodi on March 17. This testnet aims to finalize testing for Ethereum’s Prague-Electra (Pectra) upgrade. According to Ethereum developer Tim Beiko, if the testing on Hoodi proves successful, the Pectra mainnet deployment could follow within 30+ days, potentially in late April.
