Blockchain technology in its modern form was first launched in 2009, with its cryptocurrency Bitcoin. Since then, many blockchains have been developed, having different features and purposes. The total number of blockchains is not precisely known, but it is clear that blockchain technology is growing at a disruptive pace. It has use cases in every sector, including healthcare, real estate, banking, logistics, supply chain management, and many others.

The global blockchain technology market size was estimated at USD 31.28 billion in 2024 and is projected to reach USD 1,431.54 billion by 2030, growing at a CAGR of 90.1% from 2025 to 2030. The escalating demand for secure and transparent transactions across many industries is driving the market growth.

Additionally, every decentralized application is being built on a blockchain platform, whether a Web3 game or a cryptocurrency trading platform. There are numerous options available for business owners and developers to choose from when selecting a blockchain; this is why it’s challenging to pick the perfect one that suits your requirements. In this blog, we will discuss the top blockchains to look out for in 2026, their features, and limitations.

Top Blockchains Powering the DeFi Revolution

Here are a few blockchains known that are considered top-notch for decentralized app development, and have multiple other applications:

Stellar

Stellar is a fast, affordable, efficient, and scalable blockchain, designed to create and send digital assets to reach users everywhere seamlessly. The primary feature of the Stellar blockchain is that it allows users and organizations to make cross-border transactions, leveraging smart contracts. It is also used for asset tokenization, creating mobile wallets, and banking applications.

Advantages of Stellar Blockchain

• Faster and Cheaper: One of the most significant benefits of the Stellar blockchain is that it allows users to execute transactions very fast, and the transaction cost is also low.
• Multi-currency support: Stellar blockchain provides a multi-currency support feature that allows users to make payments in fiat or cryptocurrencies smoothly.
• Stellar Consensus Protocol: Like Proof of Work consensus protocol, which consume high energy, the Stellar Consensus Protocol (SCP) utilizes federated Byzantine agreement (FBA) for consensus. It is energy-efficient, fast, and avoids mining.

Limitations of Stellar Blockchain

• Low Liquidity: The utility token of the Stellar blockchain is Lumen (XLM), which provides low liquidity in the crypto trading market. It is still not considered a promising cryptocurrency for trading.
• Smart-contract Functionality: It has a limited smart-contract functionality; Stellar does not support Turing-complete smart contracts like Ethereum.
• Limited Growth: The Ecosystem of Stellar blockchain is not as big as Bitcoin, Ethereum, and Solana. The possibilities of growth are limited.

Tron

Tron is a blockchain network that users prominently utilize to create decentralized applications and exchange media assets. It fosters decentralization, and there is no central authority present. Tron has a community of users who are incentivized for their contribution to the network in the form of TRX, which is the native cryptocurrency of the Tron network. The Consensus protocol of Tron is the Delegated proof-of-Stake (DPoS), which is an energy-saving mechanism.

Advantages of Tron

• Low-Transactions Fees: Tron offers very low transactions or negligible fees to the users. They can avail of other features of the Tron network through their TRX token.
• Smart Contract Support: Tron powers Turing-complete smart contracts, thereby enabling intricate dApps, DeFi, and NFTs. The platform is developed in the Solidity language; thus, it is straightforward for an Ethereum developer to migrate.
• High Scalability: The most considerable benefit of the Tron blockchain is that it offers extremely high scalability. The network is capable of processing 2000 transactions per ‍‌‍‍‌‍‌‍‍‌second.

Limitations of Tron

Tron blockchain has following shortcomings:

• Low-quality Dapps: Tron is known for hosting numerous gambling and pyramid-style apps, which may undermine its long-term credibility.
• Regulatory Scrutiny: Tron has faced regulatory scrutiny in the past, which has affected its credibility and partnership prospects.

Ripple

Ripple, founded in 2012, is a blockchain network used for cross-border payments. Ripple’s payment, custody, and stablecoin solutions enable financial institutions to integrate blockchain and digital assets into their businesses in a simple, secure, and compliant manner. Ripple functions on the Ripple Protocol Consensus Algorithm (RPCA), which is a fault-tolerant protocol. The native cryptocurrency of the Ripple blockchain is XRP.

Advantages of Ripple

• ‍‌‍‍‌‍‌‍‍‌Quick Settlements: The transaction speed is higher than that of Bitcoin and Ethereum, as most of the transactions are settled within 3-5 seconds. Thus, it is the best option for real-time transactions and cross-border transfers.
• Low Costs: The cost of the transaction is kept at a very low level, which is close to being negligible.
• High Throughput: The throughput of Ripple is extremely high as it is capable of processing 1500 transactions per ‍‌‍‍‌‍‌‍‍‌second.

Limitations of Ripple

• Regulatory Uncertainty: Ripple/XRP ledger has faced lawsuits in the past, and those are not entirely resolved. This has put a question mark on the credibility of the network.
• Network Participation: To become a trusted validator in RPCA, one must build a reputation and be included in the Unique Node List (UNL). However, this is particularly challenging for new participants.

Solana

Solana is a high-performing, low-cost blockchain network that helps users make fast, secure, and affordable transactions. Developers can build scalable games, banking apps, and other decentralized platforms. It also allows buying, selling, and showcasing NFTs—unique digital items such as art, music, and virtual real estate. Support artists directly, without gallery commissions. The collection travels with users across platforms and cannot be deleted due to platform changes.

Advantages of Solana

• High-Scalability: The scalability of the Solana blockchain is very high. It can process 50,000-65,000 TPS on its base layer.
• Low Fees: The transaction fees on the Solana blockchain are very low, making it best suited for small transactions and gaming.
• Developer-friendly: Solana powers multiple applications and allows developers to create games and NFTs by providing simplified dApp development.

Limitations of Solana

• Centralization Issues: The primary concern about the Solana blockchain is that a small number of entities have control over large stakes, raising serious questions about the decentralization policy and pointing towards potential centralization.
• Security Threats: Some DeFi hacks and NFT exploits have been reported to have happened on the Solana dApps. The primary reason behind this is the speed and complexity of its architecture, which has made its smart contracts vulnerable to bugs and errors.
