Celo is an open blockchain platform that was created to help achieve financial inclusion and improve economic equality in developing countries. Celo provides the ability to send and receive money using mobile devices and also supports the creation and use of decentralized applications.

Celo uses a carbon-negative blockchain, which means it emits less carbon dioxide into the atmosphere than traditional blockchains. This is achieved by using a protocol called Proof of Stake, instead of Proof of Work, which is used in Bitcoin and some other blockchains. Proof of Stake reduces the amount of energy required to mine blocks, thereby reducing the carbon footprint of the blockchain.

Celo also supports a stablecoin, Celo Dollar (cUSD), which is linked to the US dollar and has a stable exchange rate. This allows Tselo users to store and send money without worrying about cryptocurrency price fluctuations.

In addition, Tselo provides functionality that allows users to send money to each other using only mobile numbers, making the process of sending and receiving money more convenient and accessible.

Overall, Celo is a blockchain platform that strives to create a more accessible, secure and sustainable financial system for all people, especially in developing countries.
