When blockchain projects promote their technology, they almost always lead with a number followed by “TPS.” You might hear claims of ten thousand or even one hundred thousand TPS, making it sound like a higher number automatically equates to a superior network. In my early days of building RizeCoin (RZC) with zero technical knowledge, I also fell for the allure of these big numbers. I thought speed was everything.

However, I eventually realized that TPS is much like a speedometer in a car. A car might have a speedometer that goes up to 300 km/h, but that doesn’t mean it is safe to drive at that speed on a bumpy road, or that the car is even capable of reaching it in daily traffic. We need to look past the marketing and understand how this measurement actually affects our experience as users.

In the landscape of 2026, where blockchain is becoming part of our daily infrastructure, understanding “Transactions Per Second” is essential for recognizing which networks are truly built for the long term.

The Supermarket Checkout Analogy

To visualize TPS, imagine the checkout counters at a busy supermarket. Every customer represents a transaction, and the checkout process represents the validation and recording of that transaction on the blockchain.

TPS is simply the measure of how many customers can finish their payment and leave the store in a single second. If a store only has one slow cashier who takes several minutes per person, the TPS is very low. A massive line will form, and people will get frustrated. On the other hand, a store with hundreds of high-speed automated kiosks has a high TPS. It can handle a huge rush of people simultaneously without anyone having to wait.

For a blockchain to serve as a global infrastructure, it must have a high enough TPS to ensure that millions of people can “check out” at the same time without the system grinding to a halt.

How TPS is Calculated

TPS isn’t a magical number; it is a result of how a specific blockchain is designed. Two main factors usually determine the limit. The first is “Block Size”—how much transaction data can fit into a single block (the delivery truck). The second is “Block Time”—how often a new block is generated (how frequently the trucks arrive).

Networks like Polygon PoS achieve a high TPS by having very short block times, meaning they process batches of transactions almost constantly. Newer technologies such as zkEVM take this further by using advanced math to compress thousands of transactions into a single proof. This effectively multiplies the TPS because more work is being done within the same amount of space.

Furthermore, the introduction of the AggLayer allows multiple chains to work in parallel. Instead of relying on the speed of one single chain, the entire ecosystem can combine its processing power, pushing the collective TPS to levels that were once thought impossible.

Why High TPS Equals Fairness

For me, high TPS is not just a technical achievement; it is a matter of empathy and inclusion. When TPS is low, the network becomes congested. In a congested network, users have to bid against each other by paying higher fees to get their transactions processed first. This “fee war” is what makes blockchain expensive and inaccessible for many.

If a network can only handle 15 transactions per second, it will naturally prioritize those who can afford to pay the most. This excludes the very people I want to help with my experiments in the blockchain space. However, when a network has a high TPS, there is plenty of room for everyone. Competition for space disappears, and transaction fees remain consistently low—often less than a cent.

This abundance of capacity is what allows user-friendly features like the Gas Station to exist. It allows us to build systems that prioritize accessibility over profit, making the technology “kind” to its users.

The Trap of Theoretical Numbers

It is important to be cautious when reading about TPS. There is often a large gap between “theoretical maximum TPS” and “actual live TPS.” This part can be difficult to grasp at first, but think of it as the difference between a car’s top speed on a test track versus its speed in a real city during a rainstorm.

Some networks claim high TPS by sacrificing decentralization—meaning they only use a few powerful servers to process everything. While this is fast, it makes the network less secure and more like a traditional bank. The goal of the 2026 blockchain era is to maintain high speed while keeping the network open and decentralized, supported by a wide variety of validators incentivized by tokens like POL.

Short Closing Reflection

Ultimately, TPS is a measure of how many “digital heartbeats” a blockchain has. As these heartbeats become faster and more reliable, the technology moves from being a complex curiosity to a silent, essential part of our daily lives. We should cheer for higher TPS not because we like big numbers, but because high capacity is the foundation of a fair and open financial system.

If you’re interested in experiments exploring low-cost blockchain ecosystems, you can also look into RizeCoin (RZC). Seeing how these high-speed networks can be harnessed to help real people is what keeps me moving forward, one transaction at a time.
