Together, we have come up with a unique consensus PSI that embodies Participation, Security and Identity, revolutionizing the way we connect and interact in a crypto world. VerdaCity is committed to shaping a sustainable future by embedding environmental concepts into our lifestyles. We advocate "Green Verda, Green City" and are committed to building a non-PoW (Proof of Working) eco-friendly output model for PSI, which does not consume large amounts of electricity and thus reduces the impact on the environment. We believe that green living is not only about environmental protection, but also about a life-affirming "green" philosophy that reflects a positive attitude towards life through community activities. As stated in our philosophy, we will encourage and organize various environmental and public welfare activities, such as clean-up campaigns, tree planting festivals, etc., in order to strengthen community members' awareness of and participation in environmental protection. In this chapter, we will introduce the PSI Consensus. --- # Agent Instructions This documentation is published with GitBook.
