Top 4 Scalable Blockchains You Can Build on Using the Chainnodes RPC

The blockchain and cryptocurrency euphoria of 2025 started with the launch of the $Trump coin, driving the urge for crypto trading and consequently increasing the transaction volume on several chains. Additionally, blockchain adoption in other sectors is expected to grow exponentially in 2025; hence, we are expected to witness the development of new decentralized applications with unique utilities.

Building on blockchain, however, requires more than the market readiness for adoption. As a developer, it is crucial to understand that the need to rely on scalable blockchain and reliable blockchain infrastructure is as critical as the idea behind your invention. For instance, for a dApp to enjoy consistent adoption, it must be able to seamlessly onboard thousands of users, complete millions of transactions within seconds, and ensure transaction or data security.

If you want to know the best blockchain for web3 dApp building, this article offers insight into the Top 4 Scalable Blockchains you can build on using the Chainnodes reliable RPC.

1.  Arbitrum

Introduced in 2021, Arbitrum is a Layer-2 blockchain designed to reduce congestion on Ethereum by aggregating and processing transactions off-chain before sending them in batch to the Ethereum blockchain. As a Layer-1, Ethereum was developed for stability, however, achieving scalability remains an issue in the face of growing demand. Hence, Arbitrum was introduced to replace the number of small transactions initiated on Ethereum with bulk Layer-2 transactions – a single transaction sent to Ethereum for approval contains hundreds of transactions initiated on L2 chains like Arbitrum.

Arbitrum achieved enhanced efficiency compared to the Layer-1 chain, given its reliance on two technologies.

  • The Optimistic Rollup Technology: Once a transaction is initiated, Optimistic Rollup assumes that the transaction is valid by default; hence, transactions on Arbitrum are processed at breakneck speed unless disputed.
  • Arbitrum Virtual Machine (AVM): AVM executes smart contracts with full compatibility to the Ethereum Virtual Machine, ensuring that developers can seamlessly migrate existing dApps from the Ethereum blockchain to Arbitrum.

Why build on Arbitrum?

  • Lower gas fees
  • Anti-fraud protection from rollup technology
  • Enjoys the security feature of Ethereum

2.  Gnosis Chain

The innovation of the Layer-2 blockchain is not restricted to rollup technology only. Instead, some blockchains are developed as sidechains designed to run parallel to a main chain (usually an existing Layer-1 chain). One such blockchain is the Gnosis Chain. As a Layer-2 sidechain built on Ethereum, Gnosis offers users and developers the opportunity to interact with Ethereum blockchain through a faster and more scalable option.

As a sidechain, the Gnosis chain is able to facilitate swift transactions relying on the Two-Way Peg mechanism. With this, users can efficiently interact with the mainchain and the side chain while assets are securely locked and transferred between the two chains. For instance, a simple transaction process on a sidechain requires the locking of assets on the mainchain. The asset is then recreated on the sidechain for users to access.

Why build on the Gnosis Chain?

  • Enhanced interoperability for cross-chain transaction.
  • EVM-compatibility for seamless dApp migration.
  • The use of stablecoin for gas fees prevents asset volatility.

3.  zkLink Nova

While it is true that Layer-2 blockchains are worth the hype, building decentralized applications got extensively better and easier with Layer-3 chains like zkLink Nova. As a Layer-3 chain, zkLink Nova combines the security benefits of Layer-1 chains with the scalability features of Layer-2 zero-knowledge rollup technology and other innovative features.

zkLink Nova features the following technology

  • Canonical rollup bridge: One of the leading features of zkLink Nova is its ability to facilitate swift multi-chain transactions. The blockchain features a Canonical rollup bridge that is used to enable asset aggregation and management through a unified interface, allowing liquidity to flow from one blockchain to another without friction.
  • Chain abstraction: For developers, zkLink Nova offers a way to build genuinely decentralized yet flexible dApps through its chain abstraction property. By eliminating the restricting blockchain infrastructure that constrains dApps to a single chain, zkLink Nova reduces the complexity of cross-chain interaction while increasing the adoption rate.

Why you should build on zkLink Nova

  • Cross-chain interoperability.
  • High liquidity through asset aggregation.
  • Low fees for cross-chain transaction.

4.  BNB Chain

Launched in 2022, BNB Chain was introduced with a dual-architecture framework designed to introduce a scalable blockchain that allows users to facilitate transactions at low fees and allows developers to build or migrate dApps to an EVM-compatible environment. It features both the Binance Chain (Bep2) and Binance Smart Chain (BSC). This design allows for seamless interoperability between a high-performance blockchain optimized for fast transactions (Binance Chain) and a smart contract-enabled blockchain supporting Ethereum Virtual Machine (EVM) compatibility (Binance Smart Chain).

Aside from the blockchain architecture, the BNB Chain achieves decentralization, security, and high throughput using a unique consensus mechanism known as Proof of Staked Authority (PoSA)

  • Proof of Staked Authority (PoSA): It is a consensus mechanism that combines the element of Proof-of-Stake (PoS) and Delegated Proof-of-Authority (DPoA) to ensure swift block validation and secure transaction.

Why build on the BNB Chain?

  • A robust ecosystem enhances the ease of adoption and compatibility.
  • Features a storage system where developers can store, share and exchange data.
  • Enhanced EVM-compatibility features.

Why You Should Build on Arbitrum, zkLink Nova, Gnosis, and BNB Chain Using Chainnodes RPC

Building on blockchains becomes a more simplified process when you access the Chainnodes RPC and API for the dApp building, deploying, and launching process. But beyond this, you also get to enjoy the following benefits:

  • Robust Web3 dApps Compatibility: Chainnodes RPC service is suitable for various dApps, including NFT, GameFi, exchange platforms, and cryptocurrency wallets.
  • Free access to reliable RPCs and API: Leverage the Chainnodes starter package to access quality tools for $0. Get more benefits at competitive prices.
  • Anonymity: Chainnodes promote true decentralization by allowing developers to access blockchain data through decentralized log-in.
  • Flexible payment: Pay in fiat or crypto.

Conclusion

Building the next industry-leading decentralized application and wondering where to start from? Leveraging the Chainnodes RPCs, API, and other blockchain infrastructure takes your building process from tedious and inefficient to a streamlined and seamless way, allowing you to focus on building dApps that meet users’ demands without retaining the problems of the old structure.
