Using a novel address-based encryption algorithm, the Celo protocol makes sending money as easy as sending a text. Additionally, Celo uses stable-value tokens pegged to fiat currencies, like the US Dollar, to minimize volatility. Celo is an open protocol enabling many to participate in the system, even with a budget Android smartphone.Â
