What is A Smart Contract?

Design by Miguel Norberto

A smart contract is a computer protocol intended to digitally facilitate, verify, or enforce the negotiation or performance.

Smart contracts allow the performance of credible transactions without third parties. These transactions are trackable and irreversible. Ethereum is a decentralized platform that runs smart contracts: applications that run exactly as programmed without any possibility of fraud or third-party interference.

Blockchain technology enables developers to create self-executing contracts called “smart contracts.” Smart contracts are executed by the blockchain network rather than a central authority. This distributed consensus mechanism ensures that all participants in the blockchain agree on the validity of each transaction and prevents fraudulent activity.

How do Smart Contracts work?

Smart contracts are a fundamental part of the Ethereum network and work similarly to regular contracts. The key difference is that smart contracts are executed automatically once all the conditions have been met. This removes the need for third-party involvement, often leading to higher costs and longer wait times.

The use of smart contracts began with the launch of the Ethereum network in July 2015. Since then, they have become an integral part of many businesses and organizations due to their security and efficiency. Smart contracts are written in Solidity, specifically designed for Ethereum.

Smart contracts are computer protocols that facilitate, verify, or enforce the negotiation or performance. They can be used in various industries but are most commonly associated with the blockchain technology that underpins Bitcoin and Ethereum.

Smart contracts are executed by a network of computers that run the programming code provided in the contract. This code is designed to execute when certain conditions are met automatically. The result is a self-enforcing agreement between two or more parties that all participants can verify and trust.

Uses for Smart Contracts

The first use for a smart contract is to create a digital asset. This could be used to represent shares in a company, gold, or any other virtual asset. The agreement would store the asset and keep track of who owns it.

Another use for a smart contract is to create a digital escrow. This would be used to hold money or assets until they are released according to the terms of the agreement. For example, you could create a contract that releases money when the buyer confirms they have received their purchased product.

The final use for a smart contract is to automate contracts. This could be used for rent payments, car rentals, or anything else that can be automated using code.

Pros and Cons of Smart Contracts

Since the invention of Bitcoin in 2009, there has been a race to create the perfect digital currency. Bitcoin introduced the world to blockchain technology, a distributed database that allows for secure, transparent, and tamper-proof transactions. Ethereum took blockchain technology one step further by introducing smart contracts, which computer programs execute when certain conditions are met.

Smart contracts have many potential uses. For example, they can automate transactions, enforce agreements and reduce costs associated with contract enforcement. They can also help to reduce fraud and corruption. However, there are also some risks associated with using smart contracts. For example, they can be vulnerable to cyber-attacks and may not be suitable for all types of transactions.

When most people think of contracts, they think of a written agreement between two or more parties. However, contracts don’t have to be written. They can also be oral or even implied. A contract is a legally binding agreement between two or more people that is enforceable in a court of law.

Contracts are necessary because they provide a way for people to exchange goods and services without worrying about getting taken advantage of. In addition, the law recognizes that it’s not always feasible for people to get together and hash out an agreement face-to-face, so it provides a way for them to do so through the use of contracts.

The advent of the internet has led to the development of what are known as smart contracts. Smart contracts are computer programs that automatically execute the terms of a contract.


The future of Smart Contracts is bright. They can revolutionize the way contracts are made and executed and could significantly impact many industries.

As more and more businesses and organizations begin to adopt this technology, the benefits of using Smart Contracts will become even more apparent.
