NEO is a blockchain platform that is eco-friendly and sustainable. Blockchain technology is used to create decentralized systems that are secure, transparent, and efficient. However, the traditional proof-of-work (PoW) algorithm used by many blockchain platforms requires a lot of energy and contributes to environmental degradation. NEO has addressed this issue by using a different consensus mechanism called delegated Byzantine Fault Tolerance (dBFT).

dBFT is a consensus mechanism that allows for fast and secure transactions without the need for energy-intensive mining. Instead of miners, NEO uses a network of bookkeepers who are responsible for verifying transactions and ensuring the integrity of the blockchain. This reduces the energy consumption of the network, making it more sustainable and eco-friendly.

NEO is also committed to sustainability beyond its consensus mechanism. The platform has implemented various measures to reduce its carbon footprint, such as using renewable energy sources and optimizing its infrastructure to reduce energy consumption.

In addition, NEO has a strong focus on building decentralized applications (dApps) that have a positive impact on the environment. For example, one of the dApps built on the NEO platform is a carbon credit trading platform that helps organizations offset their carbon emissions. This dApp incentivizes individuals and organizations to reduce their carbon footprint and contribute to a more sustainable future.

NEO's commitment to sustainability and eco-friendliness is an example of how blockchain technology can be used for positive social and environmental impact. By using a more energy-efficient consensus mechanism and building dApps that address sustainability challenges, NEO is paving the way for a more sustainable future.
