The Genesis of Smart Contracts
The concept of smart contracts was first proposed by computer scientist and cryptographer Nick Szabo in 1994. Szabo envisioned a digital contract that could automatically execute and enforce the terms of an agreement. However, the technology to implement this vision was not available at the time.
The advent of blockchain technology, particularly with the creation of Bitcoin in 2009, provided the necessary infrastructure for smart contracts. However, it was the launch of Ethereum in 2015 by Vitalik Buterin that truly brought smart contracts to the forefront. Ethereum introduced a blockchain platform specifically designed to facilitate the creation and execution of smart contracts using its native programming language, Solidity.
How Smart Contracts Work
Smart contracts operate on blockchain networks, with Ethereum being the most popular platform. Here’s a simplified breakdown of how they work:
- Agreement Coding: The terms of the agreement are coded into a smart contract using a programming language like Solidity.
- Deployment: The smart contract is deployed onto the blockchain network.
- Triggering Conditions: The contract is set to execute when specific conditions are met. These conditions are monitored by the blockchain network.
- Execution: Once the conditions are fulfilled, the contract automatically executes the agreed-upon actions.
- Immutable Records: The transaction and execution details are recorded on the blockchain, ensuring transparency and immutability.
