Have you ever wondered why some blockchains are faster than others? The answer lies in an important metric that few talk about but determines everything — what is TPS, or in other words, the number of transactions per second the network can handle.

This is not an arbitrary number. It directly impacts user experience, the scalability of the project, and even the practical application potential of Web3. When you understand what TPS is, you'll see why it has become a core factor in the competition among blockchains.

To get a clearer sense, let's compare it to traditional payment systems. VISA processes about 1,500 to 2,000 transactions per second — that’s the standard everyone is familiar with. But Bitcoin? Only about 5 TPS. Ethereum isn’t much better, around 10 TPS. Why is that? Because their decentralization requires verifying every transaction thoroughly, which slows down the process but ensures security and transparency.

But the problem is, when you want to run DeFi, NFTs, or real-world gaming applications on the blockchain, speed is essential. What is TPS if not the key to enabling these applications to operate at scale? A slow network is just a network left behind.

Some blockchains have recognized this and started taking action. Hedera leads with 1,909 TPS currently and can reach up to 3,287 TPS. Solana isn’t far behind with 777 TPS now, which can increase to 1,624. Even Tron has achieved 91.27 TPS. opBNB has 57.4 TPS but can go up to 4,762 TPS under ideal conditions. BNB Chain remains stable at 52.5 TPS with a maximum capacity of 1,731.

But here’s where balance becomes complicated. Increasing TPS isn’t free. When you want higher TPS, you often have to trade off decentralization or security. Some blockchains use off-chain solutions, increase block size, or change their consensus algorithms. These choices can impact the integrity of the network.

Therefore, understanding what TPS is isn’t just about big numbers. It’s about balancing speed, security, and decentralization. As blockchain technology continues to evolve, projects will need to find ways to achieve all three. That’s the real challenge, and it will determine which blockchains succeed in the future.
