Oracle

The whole point of smart contracts is that they need to be more secure and efficient than traditional contracts. So where do smart contract oracles fit in? In the final installment of our three-part series, Toptal Blockchain Developer John R. Kosinski explains the role of oracles in the evolution of trust.

Solidity is the programming language of choice for Ethereum and the de facto industry standard for smart contract development. In the second article of our three-part series, Toptal Blockchain Developer John R. Kosinski takes a closer look at Solidity quirks and features, explaining how to make the most of it.

Oracles are changing the way we view and create smart contracts. How do we implement them in Ethereum, using nothing but Solidity and standard dev tools? In the first article of our three-part series, Toptal Blockchain Developer John R. Kosinski explains how to get started and compile a smart contract with oracles.
