On April 16, according to official news, Arweave's scalable blockchain network AO announced the launch of the 'Network Availability Staking Alpha (NASA)' test program. This marks a key step in the AO ecosystem, aiming to enhance the availability and reliability of decentralized data networks through a staking mechanism. The program is currently in the Alpha phase, allowing users to participate in network availability verification and earn rewards by providing data services for Arweave gateways and staking AO tokens. In the initial pilot phase, AO introduces the 'Availability Staking' mechanism, requiring node operators to stake 25 AO tokens to participate in the network, competing collectively for the speed and stability of responding to user requests. The system will allocate rewards from a monthly reward pool of 1,000 AO based on the nodes' performance in data services. This mechanism relies on the next-generation HyperBEAM architecture, which enables a higher degree of verifiability and trustlessness for gateways and routing services while significantly reducing operational costs. The project team stated that NASA aims to establish a stronger decentralized economic model for the entire permanent network infrastructure, paving the way for future expansions into areas such as computing scheduling, data indexing, and network services. Although the current reward scale is small and still in the testing phase, the program is seen as an important starting point for the AO-Core economic system and will gradually expand to more network infrastructure services in the future.
