## We are delighted to announce that DIA has integrated its oracle infrastructure with Celo, the mobile-first layer1 blockchain for dApps and crypto payments.

[Celo](https://celo.org/)’s aim is to empower anyone with a smartphone anywhere in the world to have access to financial services, send money to phone numbers, and pay merchant users on a decentralized platform that is operated by a community of users. To achieve this, Celo provides a complete stack of a new **L1 blockchain network** , **core smart contracts** that run on that blockchain and enable **end-user applications**.

1. The layer 1 **Celo Blockchain** maintains full EVM (Ethereum Virtual Machine) compatibility for smart contracts. However, it uses a Byzantine Fault Tolerant (BFT) consensus mechanism rather than Proof of Work, and has different block format, transaction format and gas payment and pricing mechanisms.
2. A set of **smart contracts** running on the Celo Blockchain form many of the platform features including ERC-20 stable currencies, KYC, proof-of-stake and governance capabilities. These smart contracts are upgradeable and managed by Celo’s decentralized governance.
3. **Applications for end users** built on the Celo platform make up the third layer. The Celo Wallet app, the first of an ecosystem of applications, allows end-users to manage accounts and make payments securely. Other dApps include the DEX [_Ubeswap_](https://ubeswap.org/) or the lending platform [_Moola_](https://moola.market/).

We are delighted to announce the new integration with Celo within our continuous efforts to provide the DIA oracle suite to the ever-growing number of new L1 and L2 networks. **DIA’s broad set of on-chain and off-chain data feeds are available to developers building dApps on Celo’s mobile-first blockchain network.**

**The integration will enable new end-user applications on Celo to ingest DIA’s data feeds** including an extensive library of crypto, DeFi as well as traditional assets, open-sourced with transparent methodologies.
