Cardano Over Coffee 
W/ Charli3 Cardano’s decentralized oracle
Charli3 Oracles - In a direct response to the scaling issues plaguing Ethereum, #cardano (ADA) was developed as a quicker, inexpensive, and more secure blockchain infrastructure.
ADA is also one of the only Blockchain projects that has been built via a peer-reviewed and researched based approach.
For an oracle built on Cardano this means the backbone of its network is built on a trusted, open source foundation adding another layer of trust for users.
Charli3 is the first decentralized oracle network for the Cardano blockchain. By being native to Cardano, Charli3 aims to avoid the notable issues with flexibility, scaling, and growing transaction fees seen with Ethereum-based oracles while also building its foundation on a trusted network.
