Smart Contracts: Automating Trust


Understanding the Basics

Smart contracts, often hailed as the future of agreements and transactions, are self-executing contracts with the terms of the agreement directly written into lines of code. These contracts are executed and enforced automatically when predefined conditions are met, without the need for intermediaries.

Origins of Smart Contracts

The concept of smart contracts can be traced back to the early 1990s when computer scientist and legal scholar Nick Szabo first introduced the idea. Szabo envisioned self-executing contracts with code and protocols replacing traditional legal documents.

How Do Smart Contracts Work?

To understand smart contracts better, it's essential to delve into their mechanics. These contracts operate on blockchain technology, which ensures transparency, immutability, and security. When specific conditions encoded in the contract are met, the contract is executed, and the associated actions are performed automatically.
