When discussing blockchain performance, the metric TPS (Transactions Per Second) is indispensable. Understanding how important this is in the IT world is truly a key point when considering the practicality of 暗号資産.

Recently, I revisited this metric, and surprisingly, not many people have a solid understanding of what TPS actually is. Simply put, it refers to the number of transactions a blockchain can process per second. For comparison, traditional payment systems like VISA handle about 1,500 to 2,000 transactions per second, which has become a benchmark for digital payments.

However, early blockchains like ビットコイン and イーサリアム each process around 5 TPS and 10 TPS, respectively. That’s quite slow. But there’s a reason for this. They prioritize security and transparency to maintain their decentralized nature. It’s a classic trade-off.

Why is TPS important? Because for Web3 projects—especially DeFi, NFTs, and real-time gaming applications—processing speed directly impacts usability. Users expect performance comparable to centralized services, so delays and bottlenecks are major barriers to adoption.

Recent blockchain development involves various approaches to improve TPS. These include optimizing block size, refining consensus algorithms, and implementing off-chain solutions. However, whether these improvements compromise decentralization or security is always a topic of debate.

In fact, some chains have made significant progress. Hedera currently achieves 1,909 TPS, with a maximum of 3,287 TPS. Solana processes 777 TPS and can handle up to 1,624 TPS. Tron operates at 91.27 TPS, opBNB at 57.4 TPS, and BNB Chain at 52.5 TPS. Each chain’s governance model and block time differ, reflecting their unique design philosophies.

Ultimately, high TPS alone isn’t the only answer. Balancing security and decentralization is crucial. As blockchain technology matures, systems that can simultaneously deliver high speed, robustness, and broad decentralization will be the ones to succeed in the market. The future of innovation depends on how well these three elements can be integrated.
