Celestia has launched a public testnet named Mamo-1, which features 128MB blocks and enables a data throughput of 21.33MB/s. This testnet represents a significant increase in capacity, being 16 times the throughput of Celestia's mainnet, and is the result of over a year of research and engineering focused on a new blazing-fast block propagation protocol. In other blockchain developments, Euler has been awarded a 500K $OP grant to expand its lending super app to the Optimism network. Additionally, Euler's launch on the Avalanche network has seen rapid growth, surpassing $100 million in value within days, described as 'melting faces'. This expansion is set to enhance the utility of avUSD within the Avalanche ecosystem.
