#PiNetwork launched its closed mainnet in December 2021 and entered a gradual transition period to an open mainnet in February 2025. Currently, only internal ecosystem transfers are available, and trading is possible on a few KYB-certified exchanges, but cross-chain and external wallet transfers are not yet supported. Full node empowerment and complete open-source implementation are not yet finalized. Based on a comprehensive progress forecast, full node empowerment and open-source implementation are expected between the end of 2026 and the first half of 2027, with the final implementation pace influenced by KYC coverage, ecosystem development, and global compliance policies. Once node empowerment is achieved and the underlying source code is fully open-source, coupled with some revolutionary features of the Pi Web3 public chain, perfect integration with the existing internet, and combination with AI, it will undoubtedly amaze everyone. Persistence will ultimately lead to a bright future. Go Pi! 👏
