DevvE is a cryptocurrency designed to support efforts in addressing environmental and social challenges by creating a financial model to support the operational costs of developing and maintaining the security and transparency of ESG data and assets, and generating funds for investments in green projects that support ESG goals and create additional ESG assets. DevvE is also the platform cryptocurrency for the DevvX blockchain. The DevvX blockchain platform is an ISO-compliant green blockchain due to its ultralow power consumption - with 1/3 billionth the energy consumption of Bitcoin. DevvX is a unique layer 1 blockchain that is comprised of shards, or independent blockchains, that can communicate through a novel cross-shard mechanism. The transparency of DevvX blockchain shard data is expected to be managed by DevvE cryptocurrency ownership. Entities that contribute to the transparency of ESG data will run DevvX Verification Nodes whereby each shard’s blockchain data will be continuously duplicated in full. DevvE can be used both as a reward for providing this valuable trust-enabling service, as well as enabling governance around which entities run Verification Nodes.
