Modular blockchain network Celestia has launched an incentivized testnet program, the Blockspace Competition, which will select 1,000 participants, including validators, bridge nodes, full storage nodes, and light nodes. The Blockspace competition is divided into five phases and will last for nine weeks. In each phase, participants will receive assignments related to their roles and compete for points by completing tasks. The first phase starts on March 7. Additionally, new features for the testnet include: IBC transfers, more efficient syncing, and an improved API for interacting with Celestia data availability nodes.
