Smart Contracts 101: Understanding the Backbone of Web3

In the rapidly evolving landscape of Web3 technology, one concept has emerged as a cornerstone of innovation: Smart Contracts. These self-executing contracts with the terms of the agreement directly written into code are changing the way we transact, automate, and envision the future of decentralized systems.

You may be curious about Smart Contracts if you are thinking about joining any Web3 companies and making it your future. Here is an introduction to Smart Contracts, their history, what they are, how they work, and what advantages they offer to top Web3 companies on a larger scale.

The History of Smart Contracts

Smart Contracts are not a new phenomenon, but the term gained prominence with the advent of blockchain technology. Nick Szabo – a legal scholar and computer scientist – first introduced Smart Contracts to the world. He envisioned a digital protocol for verifying, facilitating, and enforcing negotiations of a contract in a safe manner without the need for intermediaries. However, it wasn’t until 2015, with the launch of Ethereum, that Smart Contracts became what they are right now and became a main service of Web3 companies.

What Are Smart Contracts?

A Smart Contract is fundamentally a piece of blockchain code. Its execution is triggered when predetermined conditions are met, and it contains a set of rules and regulations that have been agreed upon by the parties involved. It is essentially a self-executing contract with terms expressed in code as opposed to formal legal language.

Smart Contracts operate on the “if-this-then-that” logic. For example, if Party A delivers a certain quantity of goods, then Party B automatically releases the funds. This automation eliminates the need for intermediaries, reducing both costs and the potential for disputes.

How Do Smart Contracts Work?

Smart Contracts need blockchain technology to function. These contracts are deployed on blockchain platforms. One of the most widely used platforms for this is Ethereum. Blockchain companies do use other platforms, though, like Solana, Corda, and Cardano.

A Smart Contract’s terms are agreed upon by parties and then recorded in the blockchain. This decentralized nature ensures transparency and security. Once deployed, the smart contract waits for the specific conditions to be met. These conditions could include a certain date, the fulfillment of a task, or an external trigger.

The contract is automatically executed upon satisfaction of the requirements. The blockchain network’s code is implemented, guaranteeing security and consensus. This results in a secure and foolproof system where there is no centralized authority.

Advantages of Smart Contracts

Trust and Security

Smart Contracts are secured by blockchain technology, which makes them highly resistant to tampering or fraud. Once deployed, the terms of the contract are permanent and can’t be altered without the consensus of the network. All parties have real-time access to the transaction records and have full transparency. The security of these contracts is foolproof!


The fact that Smart Contracts are self-executing and do not require middlemen is one of their main characteristics. Errors decrease and efficiency increases in the execution process. This not only saves time but also reduces costs associated with traditional contract execution processes and third-party fees.


The nature of blockchain technology ensures transparency in all aspects, and Smart Contracts are no different. All parties involved in a Smart Contract will view its terms and will have access to its nitty-gritty at all times. They can keep track of its execution as well. This has helped in fostering trust among the participants!

Cost Efficient

Traditional contracts often involve various intermediaries. Entities such as notaries, lawyers, and banks are often involved, and companies bear extra costs for their services. These middlemen are superseded by Smart Contracts, which also lower their associated costs. It streamlines everything and considerably eases everyone’s life.

Uses of Smart Contracts Outside of Web3 Companies

Smart Contracts can be used in multiple industries and not just by Web3 companies. The universally beneficial qualities of these contracts make them an asset that cannot be ignored. Some of the ways Smart Contracts can be employed in different ways are:

Supply Chain Management

Smart Contracts can automate and streamline supply chain processes. They can be programmed to trigger payments upon successful delivery of the products, provide real-time tracking, and even automatically update inventory. It removes the need for paper-based systems and makes everything automatic or digital.

Healthcare and Insurance Claims

Smart Contracts and blockchain technology can be used in the healthcare system. It can also help with insurance claims. Patient information and records can be stored on blockchain technology with a private key to access those records shared with only a select few. Among the parties with access to these records can be insurance companies. Patients won’t have to worry about getting access to medical care because it can make insurance claims much simpler.

On A Final Note

As the technology behind Smart Contracts continues to mature, their adoption is expected to grow across various industries. These secure contracts allow parties to work in transparency and without the need for intermediaries. It lowers expenses, simplifies procedures, and greatly streamlines the process. It genuinely cuts across industries and could change the game.
