Blockchain continues to revolutionize industries, driving innovation in finance, healthcare, supply chain, and more. With the global blockchain market expected to generate a total revenue of around $94 billion by 2027, its popularity shows no signs of slowing down. Central to this revolution are smart contracts—self-executing agreements that automatically enforce terms without intermediaries. They're powering everything from decentralized finance (DeFi) to NFT markets and beyond.
In this blog, we’ll dive into the top 12 blockchain platforms that are redefining smart contract development in 2024. From transaction speed to consensus mechanisms, we’ll explore the essential factors that make a blockchain platform suitable for smart contracts today.
Whether you’re a developer, investor, or blockchain enthusiast, this guide will give you insights into the best platforms to consider for smart contracts.
Before we get into how blockchain platforms can contribute to smart contract development, it is important to understand what they are and how they function.
Blockchain platforms are the foundational frameworks that power decentralized applications and smart contracts. At their core, blockchain platforms consist of nodes that validate and record transactions across the network. Each transaction is added to a block and secured with cryptography, ensuring that data remains immutable.
Smart contracts, which are self-executing pieces of code, run on these platforms. Once the contract’s conditions are met, the platform executes the agreement without requiring intermediaries.
These blockchain platforms create the environment for developers to write, deploy, and execute self-executing contracts. They manage all backend processes, including transaction verification and data storage, ensuring that once deployed, contracts are secure and immutable.
There are a plethora of blockchain platforms to choose from. Hence, it is important to have fixed criteria in mind when picking the right platform to work with. These fixed criteria can comprise the following important factors:
With the above-mentioned key factors as our guide, we have come up with an updated, informative, and accurate list of the topmost blockchain platforms to consider for smart contract development in 2024. They are:
Ethereum remains a leader in smart contract development. It utilizes Solidity and Vyper as its primary smart contract languages, offering robust support for complex applications. Ethereum’s consensus mechanism is Proof of Stake, enhancing scalability and energy efficiency compared to Proof of Work. With an average transaction speed of 13–15 seconds, Ethereum is highly versatile, supporting a wide range of decentralized applications (dApps) and financial services.
Arbitrum is a layer-2 scaling solution for Ethereum, designed to improve transaction speed and reduce costs. Developers write smart contracts in Solidity, ensuring compatibility with Ethereum's ecosystem. Transaction costs on Arbitrum are significantly lower compared to Ethereum, and the platform supports a variety of dApps and DeFi projects.
Hyperledger is a suite of open-source blockchains and tools aimed at enterprise use. It does not use a single smart contract language but supports various programming languages, including Go and Java. Hyperledger uses consensus mechanisms like Practical Byzantine Fault Tolerance (PBFT) and offers high transaction speeds and low costs.
Cardano distinguishes itself with a research-driven approach to blockchain technology. It employs the Haskell-based Plutus language for smart contracts and uses a Proof of Stake consensus mechanism called Ouroboros. This setup ensures high security and scalability while maintaining energy efficiency. Cardano’s transaction speeds are competitive, and costs are generally low.
Polkadot enables different blockchains to transfer data and assets seamlessly through its relay chain and parachains. It supports smart contracts written in Ink! and Substrate, its own framework. Polkadot’s transaction speeds are impressive, and costs are generally low due to its efficient design.
Binance Smart Chain is known for its high performance and low transaction costs. It supports smart contracts written in Solidity, making it compatible with Ethereum-based projects. BSC uses a Proof of Staked Authority (PoSA) consensus mechanism, which combines elements of Proof of Stake and Proof of Authority, offering fast transaction speeds and minimal fees.
Tezos is a self-amending blockchain that supports smart contracts through its Michelson language. It uses a proof-of-stake consensus mechanism, offering energy efficiency and scalability. Transaction speeds are reasonable, and costs are low.
Stellar is designed for cross-border payments and financial applications. It uses the smart contract language Stellar Smart Contracts (Stellar SDK), which is geared toward financial transactions. With average transaction speeds of a few seconds and low fees, Stellar excels in creating a bridge between different currencies and financial systems.
Optimism is another layer-2 scaling solution for Ethereum, utilizing Optimistic Rollups to enhance transaction throughput and reduce costs. It supports Solidity for smart contracts, ensuring compatibility with existing Ethereum projects. The platform’s transaction costs are lower compared to Ethereum’s base layer, and speeds are significantly improved.
Polygon is a layer-2 scaling solution that enhances Ethereum’s capabilities. It supports smart contracts in Solidity and uses a variety of consensus mechanisms, including Proof of Stake and Plasma. Polygon offers rapid transaction speeds and minimal costs, making it a popular choice for dApps and DeFi projects.
Cosmos focuses on interoperability and uses smart contracts written in CosmWasm whilst employing a Tendermint-based consensus mechanism. It offers high transaction speeds and low fees, providing a scalable solution for blockchain networks seeking to connect with others.
Algorand is known for its high-speed transactions and low fees. It supports smart contracts through its Algorand Smart Contracts (ASC1) language and utilizes a Pure Proof of Stake consensus mechanism. This setup ensures fast and secure transactions with minimal costs.
It is important to choose the right blockchain platform for smart contract development as per all your requirements and budget constraints, as well as the factors that each platform characterizes. To make your decision easier, we have come up with the following:
As we move through 2024, certain trends and platforms are poised to shape the future of blockchain technology. Blockchain adoption is projected to increase across various sectors, and blockchain platforms that offer efficient, secure, and scalable smart contract capabilities will be in high demand.
Ethereum, despite its high costs, continues to be a dominant force due to its significant role in DeFi and NFT industries. However, platforms like Polkadot and Cosmos stand out with their focus on interoperability. Cardano and Algorand, with their strong emphasis on security and scalability, are likely to attract projects requiring robust and energy-efficient smart contracts.
Each blockchain platform brings unique strengths to the table. The future of blockchain technology will likely be defined by these innovations and the ability of these platforms to adapt to emerging industry demands.
Blockchain platforms are digital infrastructures that support the creation and execution of smart contracts. They handle backend processes such as transaction verification and data storage, ensuring contracts are tamper-proof and irreversible.
Key factors include transaction cost, speed, smart contract language, scalability, and security. Evaluate these based on your project’s requirements to ensure optimal performance and efficiency.
Popular platforms include Ethereum, Cardano, Polkadot, Binance Smart Chain, and Polygon. Each offers unique features tailored to different use cases and industry needs.
Ethereum and Polygon are likely to gain more prominence due to their strong ecosystems and ongoing upgrades. However, platforms like Arbitrum and Optimism are also emerging as key players.
Choose Polygon if you need high transaction speed and low fees for dApps. Opt for Cosmos if you require cross-chain interoperability and scalable multi-chain solutions.
Platforms like Binance Smart Chain, Polygon, and Arbitrum offer lower transaction costs compared to Ethereum. They are ideal for cost-conscious projects.
