Smart Contracts: How Blockchain Programs Execute Agreements
Summary
The document explains smart contracts as programs stored on a blockchain that carry out preset actions when specified conditions are met. It describes Ethereum as enabling these autonomous programs, notes that contract code is publicly visible, and says execution on Ethereum requires gas paid to network participants. Examples include peer-to-peer transfers, decentralized finance, blockchain games, and decentralized applications.
The article presents decentralization, transparency, immutability, deterministic execution, and customizability as potential advantages over traditional agreements. It also identifies key limitations: code can contain bugs, recorded terms are difficult to change, mistakes may cause unrecoverable losses, and automated programs do not ensure that participants meet legal requirements such as age or identity. These are broad explanatory claims rather than a technical implementation guide or trading analysis. The document offers no quantitative evidence about reliability, costs, adoption, or investment performance, and its promotion of a trading platform is not part of the substantive explanation.
Key ideas
- A smart contract is a blockchain program that performs actions when its encoded conditions are met.
- Ethereum execution requires gas, and the document describes network nodes as processing transactions.
- Public, immutable code can support transparent and automated transactions without a conventional intermediary.
- Smart contracts can power decentralized finance, games, peer-to-peer transfers, and other applications.
- Bugs, irreversible mistakes, and legal or identity gaps can create serious limitations.
