Aptos has an incentivized testnet program where the Aptos team welcomes community members to help with testing. The first testnet was Aptos Incentivized Testnet 1 (AIT1) where the community and the Aptos team created and deployed a decentralized network for over a week. Those who met a 95% participation rate were rewarded. Eligible individuals who were unable to meet the original expectation, but still participated in at least 5% of the testing rounds were also offered 50% of the rewards. Aptos Incentivized Testnet 2 (AIT2) was concluded in late July 2022. The latest Aptos Incentivized Testnet 3 (AIT3) opened for registration on 19th August 2022 and will launch on 30th August 2022. Participants that meet the team's success criteria will receive 800 Aptos tokens. For more details and signup, check out the Aptos blog.
