Best 5 Blockchain-Based Smart Contract Platforms [UPDATED]

Summary

• Smart contracts in Blockchain are self-executing agreements written in code on a decentralized network.

• They eliminate the need for intermediaries and offer transparency, irreversibility, and traceability.

Think of a vending machine. All of us are familiar with the vending machine, which is found almost everywhere. This is a simple yet effective smart contract example to understand how it works. You make your choice in the machine, put in the money, and outcomes your milkshake. Instead of this, if you had gone to a regular store, you would need to interact with the cashier. This applies to all the valuable exchanges which happen in our life. If you need a document or an agreement to be prepared, in real life, you will have to take the services of a lawyer, pay them a fee, and get the document from them. 

But this is not the case with Blockchain smart contracts. In a traditional contract, there are agreements, rules, and penalties. But in a smart contract, the penalties are automatically meted out to the defaulters. As there are several Blockchains that offer the feature of smart contracts, it might be confusing to identify the best one, especially if you are new to the world of Blockchain.

In this article we will help you choose the best smart contract in Blockchain. Irrespective of whether you are a beginner or an advanced learner, this article will prove to be useful to you as it will throw light on the current top 5 Blockchain-based smart contract platforms. If you want a solid grounding before comparing them, a Certified Blockchain Expert program is a good place to start.

Understanding Smart Contracts

So, what exactly is a smart contract in Blockchain? It refers to a self-executing contract where the terms of the agreement between the buyer and the seller are directly written into lines of code. The code and the agreements contained therein exist over a distributed, decentralized Blockchain network. Smart contracts allow for trusted transactions and agreements to be carried out among anonymous parties without the need for a central entity, external enforcement mechanism, or legal system. This way, the transactions are transparent, irreversible, and traceable. Implementing smart contracts in Blockchains is made possible through Solidity, the high-level object-oriented programming language.

American computer scientist Nick Szabo was the first to propose the concept of smart contracts in 1994. He invented a virtual currency called ‘Bit Gold’ in 1998, ten years before the invention of the Bitcoin by Satoshi Nakamoto, the anonymous inventor of Bitcoin. Szabo is even rumored to be the real Satoshi Nakamoto, which he has denied. Szabo defined smart contracts as computerized transaction protocols executing the terms of the contract.

What Smart Contracts Can Do

• Manage agreements between users: Smart contracts act like digital agreements. When two or more parties enter into a contract, the smart contract ensures that the terms of the agreement are followed automatically. For example, in a rental agreement, the smart contract can release the security deposit to the landlord once the tenant has left the property in good condition.

• Multi-signature accounts: Think of this like a group decision. In some cases, you might want several people to agree before money can be spent. Smart contracts can be set up to require, let's say, 3 out of 5 people to approve a transaction before it happens. This adds an extra layer of security and trust, like when multiple people need to sign off on an important decision.

• Provide utility to other contracts: Smart contracts are like building blocks. They can be used to create more complex systems. For instance, you can have one smart contract that handles voting and another that manages funds. These can work together to create a voting system where funds are released based on the vote results.

• Store application information: Smart contracts can store data. Imagine a smart contract for a club membership. It can keep a list of all the members and their renewal dates. Or, for domain registration, it can hold records of who owns a domain and when it expires.

Anyone who wants to turn these use cases into working code can build the skills through a Certified Smart Contract Developer course.
