"The Evolution of Smart Contracts and Cryptoeconomic Security" discusses how smart contracts are improving, their growing use of oracles and new data sources, as well as the cryptoeconomic security that externally connected smart contracts will come to rely on.

Blockchain-based smart contracts are the next generation of digital agreements, providing deterministic guarantees on the execution of the contract according to its terms. However, smart contracts require a secure and reliable connection to external data existing outside the blockchain, commonly known as the “oracle problem”.

Chainlink offers multiple features to help developers overcome the oracle problem, including decentralization, provably secure nodes, high-quality data, crypto-economic security, defense-in-depth strategies, connection to numerous blockchain environments, and a large open-source development community. These features have allowed products from decentralized finance (DeFi) to enterprise-level solutions to seamlessly integrate external data into their smart contracts.

One of the most important elements of any blockchain oracle network is the use of high-quality data. To give users stronger guarantees about the quality of data, Chainlink applies binding Service Agreements between the requesting smart contract application and the node operator(s), which are cryptographically signed by both parties. The Service Agreement outlines the exact terms of service that the node operators need to provide and the penalties for not upholding the terms defined.

Sergey expands on the crypto-economic security backing service agreements by discussing implicit and explicit staking. Implicit staking refers to the idea that participants in the network will...
