Bitcoin có thể xử lý bao nhiêu giao dịch mỗi giây? Phân tích chuyên sâu về hiệu suất mạng lưới, thách thức và tương lai của Bitcoin

Imagine hundreds of millions of users around the world all hitting the payment confirmation button at once, while the main highway carrying all that traffic can only let 7 cars through per second. That’s the reality facing the Bitcoin network—its throughput is just about 7 transactions per second (TPS). TPS is a core metric for measuring the speed and scalability of a blockchain network. It directly determines the network’s transaction processing capacity and its potential for future growth.

In contrast, traditional centralized payment systems like PayPal process around 193 TPS, while the Visa network handles a staggering 1,700 TPS.

01 The Blockchain Speed Race: The Core Value and Measurement of TPS

In the cryptocurrency space, TPS is a key quantitative metric for assessing blockchain performance. It represents the maximum number of transactions a blockchain network can confirm and process in one second.

A high TPS means the network can support greater transaction throughput. For users, this translates directly into faster transaction confirmations and a lower chance of network congestion. Especially during periods of high market volatility or surging transaction demand, a high-TPS network can effectively prevent transaction delays and skyrocketing fees.

However, TPS isn’t the only performance indicator. Finality is equally crucial—it refers to the time required for a transaction to become irreversible after being confirmed by the network. For example, although Bitcoin’s TPS is low, achieving finality for a transaction typically takes about 60 minutes of block confirmations to ensure its security.

02 Bitcoin’s Trade-Off: The "Impossible Triangle" of Security, Decentralization, and Speed

Bitcoin’s TPS design is a direct reflection of its core philosophy. Through complex mathematical computations and globally distributed node validation, Bitcoin achieves unparalleled security and decentralization, but this comes at the cost of processing speed.

This trade-off leads to the well-known "blockchain trilemma": scalability, security, and decentralization—any blockchain struggles to optimize all three simultaneously, often sacrificing one to strengthen the other two. Bitcoin has chosen to prioritize security and decentralization.

According to the TPS calculation formula: (block size / transaction size) / block interval time, Bitcoin’s basic network parameters were set early on. This limits its raw processing power as a single chain and creates a significant efficiency gap compared to mature payment networks like Visa, which can process thousands of transactions per second.

03 The Real Impact of Performance Bottlenecks: Congestion, Fees, and User Experience

Bitcoin’s limited TPS creates significant challenges during bull markets or periods of high network activity. When the number of pending transactions exceeds the network’s capacity, transaction backlogs form.

The direct result of this congestion is that users must pay higher transaction fees to incentivize miners to prioritize their transactions. Market data shows that during peak times, Bitcoin transaction fees can exceed tens of dollars per transaction, making small payments or frequent trading prohibitively expensive.

From a broader adoption perspective, low TPS limits Bitcoin’s vision as "everyday peer-to-peer electronic cash." While its narrative as "digital gold" and a store of value remains strong, the bottleneck in processing speed does affect its potential for wider commercial use.

04 Breaking the Bottleneck: Layer 2 Scaling Solutions and the Road Ahead

Faced with base layer limitations, the Bitcoin community hasn’t stood still. Layer 2 solutions, exemplified by the Lightning Network, have become key to breaking through. The principle is to build a second-layer payment channel network on top of the Bitcoin main chain, allowing users to conduct unlimited, instant, and near-zero-fee transactions within the channel, with final settlement back on the main chain.

This is similar to using a credit card for daily purchases and settling up at the end of the month, which greatly relieves pressure on the main chain. According to Gate’s latest industry observations, these off-chain scaling technologies are among the core innovations addressing blockchain scalability challenges.

Additionally, future technical upgrades—such as cautious adjustments to block size and optimizations to signature algorithms—are being explored to steadily improve overall network efficiency without compromising core security.

05 Beyond the Numbers: How to Trade Efficiently in Today’s Ecosystem

For traders, understanding Bitcoin’s TPS is not just a technical concept but has real operational significance. During periods of congestion and high fees, timing your transactions and setting reasonable fees becomes especially important. Gate’s high-speed matching engine provides users with instant order execution.

Given the inherent limitations of Bitcoin Layer 1, many users are also turning to other high-throughput blockchain networks. For example, Gate offers a wide range of trading options across many high-performance public chains, supporting over 4,200 cryptocurrencies, including emerging networks like Solana with theoretically very high TPS.

Investors can easily build a diversified portfolio on Gate, combining Bitcoin (as a store of value) with other high-TPS tokens (as mediums for application and trading). The platform’s GateToken plays a significant role in the ecosystem. As of January 5, 2026, its latest price is $10.52. Notably, GateToken follows a deflationary model, having burned tokens worth over $35 million in Q3 2025 alone to enhance its scarcity.

Looking Ahead

As the Bitcoin network steadfastly guards the store-of-value crown at 7 transactions per second, Ethereum’s roadmap of merging and sharding points toward a future of 100,000 TPS.

Meanwhile, innovative public chains like Solana are pushing the boundaries with theoretical speeds in the hundreds of thousands of TPS. At the same time, platforms like Gate have incorporated hundreds of high-throughput blockchain assets, opening the door for users to the next generation of blockchain applications.
