The story of Celo

The financial system excludes roughly 1 in 3 adults. Cryptocurrencies have a number of advantages to fiat currencies as a means of payment but come with high volatility, high complexity, and haven’t made the financial system more accessible yet. Based on extensive research in emerging markets and developing countries — Tanzania, Colombia, Argentina, Mexico, the Philippines, and Kenya — Celo is building a mobile-first blockchain platform alongside a suite of financial tools to make sending a payment as easy as sending a text message. The Celo Blockchain has shared ancestry with Ethereum, and maintains full EVM compatibility for smart contracts but uses a BFT consensus mechanism, different block format, transaction format, client synchronization protocols, and gas payment and pricing mechanisms. Celo has started an Alliance for prosperity and its platform is open and allowing for an ecosystem of powerful applications.

Governance in Celo

Celo has developed its platform and core contracts internally. The foundation is responsible for education and community building of the Celo platform. Celo will use on-chain governance mechanisms to manage and upgrade the protocol, for example to upgrade Celo core contracts, to add new stable coins or change the reserve target asset allocations. Celo Gold holders will vote on proposals.
