In the rapidly evolving world of blockchain technology, speed is a critical factor that determines scalability, user experience, and real-world applicability. One of the most widely used metrics to evaluate blockchain performance is Transactions Per Second (TPS) — a measure of how many transactions a network can process in one second. As we move into 2025, several high-performance blockchains are pushing the boundaries of throughput, latency, and decentralization.
This article explores the fastest blockchains by TPS, based on real-time data from Chainspect as of July 4, 2025. We’ll dive into key metrics, compare layer-1 and layer-2 solutions, and uncover what makes certain networks outperform others in speed and efficiency.
Understanding Blockchain Speed: Why TPS Matters
Before diving into rankings, it's essential to understand what TPS truly represents. While a high TPS suggests strong scalability, it doesn't tell the whole story. Factors like finality time, consensus mechanism, network congestion, and on-chain vs off-chain execution also play vital roles in overall performance.
For developers, enterprises, and users, higher TPS means:
- Faster transaction confirmations
- Lower fees during peak usage
- Better support for decentralized applications (dApps)
- Improved potential for mass adoption
Now, let’s explore the top performers in 2025.

Top 5 Fastest Blockchains by Real-Time TPS
1. Solana – The Speed Leader
Real-Time TPS: 1,420 tx/s
Peak TPS: 65,000 tx/s
Finality Time: 0.4 seconds
Launched: March 16, 2020
Solana continues to dominate the blockchain speed race with an impressive real-time throughput of 1,420 transactions per second, far surpassing most competitors. Its hybrid consensus model — combining Proof of History (PoH) with Proof of Stake (PoS) — enables lightning-fast processing while maintaining security.
Despite past concerns about network stability, Solana has significantly improved its uptime and resilience, making it a preferred choice for high-frequency dApps, NFT marketplaces, and DeFi platforms.
2. Internet Computer (ICP)
Real-Time TPS: 1,145 tx/s
Peak TPS: 209,708 tx/s
Finality Time: 0.48 seconds
Launched: May 10, 2021
ICP stands out with an extraordinary peak capacity exceeding 200,000 TPS, thanks to its unique architecture that allows smart contracts to run directly on the blockchain without relying on external servers. This enables web-speed computation and seamless integration with traditional internet services.
Its sub-second finality and on-chain execution model make ICP ideal for enterprise-grade applications requiring high throughput and low latency.
3. Taraxa
Real-Time TPS: 232.1 tx/s
Peak TPS: 50,000 tx/s
Finality Time: 3.6 seconds
Launched: April 3, 2023
A rising star in the IoT and supply chain space, Taraxa leverages a directed acyclic graph (DAG)-based consensus to deliver fast and energy-efficient transaction processing. Designed for real-world data validation, Taraxa excels in use cases where transparency and speed are paramount.
Although its real-time TPS is lower than Solana or ICP, its specialized focus gives it a competitive edge in niche markets.
4. BNB Chain
Real-Time TPS: 187.8 tx/s
Peak TPS: 2,222 tx/s
Finality Time: 0.75 seconds
Launched: September 1, 2020
As one of the most active ecosystems in DeFi and Web3 gaming, BNB Chain maintains a solid position with consistent performance. Built on a Proof of Staked Authority (PoSA) consensus, it balances speed with moderate decentralization.
With strong backing from Binance and continuous upgrades, BNB Chain remains a go-to platform for developers seeking high throughput and low costs.
5. Stellar
Real-Time TPS: 146.8 tx/s
Peak TPS: 2,032 tx/s
Finality Time: 5.65 seconds
Launched: July 31, 2014
Stellar has quietly maintained reliable performance over the years. Originally designed for cross-border payments, it supports fast and low-cost transactions, making it popular among financial institutions and remittance services.
While not the fastest in raw speed, Stellar’s stability and long-standing track record add to its credibility.
Layer-1 vs Layer-2: A Performance Breakdown
Blockchains are often categorized as Layer-1 (base chains) or Layer-2 (scaling solutions). Layer-1 networks like Solana and Ethereum handle transactions natively, while Layer-2 solutions like Base and Arbitrum build on top of them to improve scalability.
Notably:
- Layer-1 chains tend to have higher finality times but greater autonomy.
- Layer-2 networks inherit security from their parent chain (usually Ethereum) and offer faster confirmation times at lower costs.
For example:
- Base (L2): Processes 105.2 tx/s with a finality time of just 2 seconds.
- Arbitrum (L2): Achieves 25.45 tx/s with near-instant finality due to optimistic rollup technology.

Key Performance Metrics Across Leading Networks
Beyond TPS, other metrics provide deeper insight into blockchain efficiency:
- Finality Time: How quickly a transaction becomes irreversible.
- Consensus Mechanism: Impacts both speed and decentralization (e.g., PoS, PoH, DAG).
- On-chain vs Off-chain Execution: Determines where computation happens.
- Network Uptime & Reliability: Critical for enterprise adoption.
For instance, Aptos boasts a finality time of just 0.12 seconds, among the fastest in the industry, while Hedera uses a council-governed model to ensure stability at scale.
Frequently Asked Questions (FAQ)
Q: What is the highest recorded TPS for any blockchain?
A: As of 2025, Internet Computer (ICP) holds the record with a peak TPS of 209,708, achieved through its innovative subnet architecture and chain-key cryptography.
Q: Does high TPS mean a blockchain is better?
A: Not necessarily. While high TPS indicates scalability, factors like decentralization, security, developer activity, and ecosystem maturity are equally important when evaluating a blockchain’s overall value.
Q: Can Ethereum compete with high-speed blockchains?
A: Native Ethereum processes around 18 tx/s, which is modest compared to leaders like Solana. However, Ethereum’s Layer-2 ecosystem (e.g., Arbitrum, Optimism) handles thousands of transactions off-chain, effectively boosting its total throughput.
Q: Are testnet speeds included in these rankings?
A: No — all figures reflect real-time mainnet performance as of July 4, 2025. Testnet results are excluded to ensure accuracy and relevance.
Q: Why does Bitcoin have such low TPS?
A: Bitcoin prioritizes security and decentralization over speed. With a design cap of ~7 TPS and ~10-minute block times, it’s optimized for value storage rather than rapid transactions.
Q: How do new blockchains achieve such high speeds?
A: Many leverage advanced consensus mechanisms (like PoH or DAG), parallel execution engines (e.g., Move VM), or sharding techniques to process transactions concurrently rather than sequentially.
