What is the biggest challenge facing blockchain technology in the digital age? It is processing speed.

In fact, the most closely watched metric for measuring blockchain performance is TPS, or transactions per second. This is not just a technical specification; it directly affects the user experience that people actually feel.

TPS is a term commonly used in the IT industry, but it is especially important in the context of blockchain. Traditional payment systems, such as VISA, can process 1,500 to 2,000 transactions per second. This has become an industry benchmark. Meanwhile, Bitcoin handles about 5 TPS, and Ethereum about 10 TPS. The reason is simple: due to its decentralized nature, security and transparency are prioritized.

But think about it. For Web3 applications like DeFi, gaming, and NFT marketplaces to truly become widespread, they need to overcome this speed barrier. Low TPS leads to transaction congestion, causing users to shift to traditional centralized services. This significantly hampers adoption.

Recently, blockchain projects are earnestly addressing this challenge. Hedera currently supports 1,909 TPS, with a maximum of 3,287 TPS. Solana reaches 777 TPS, with a maximum of 1,624 TPS. Projects like Tron, opBNB, and BNB Chain are also continuously achieving higher speeds.

Of course, an important conflict arises here. Increasing TPS by enlarging block size, changing consensus algorithms, or introducing off-chain solutions can compromise the blockchain’s inherent decentralization and security. In other words, the more speed is prioritized, the further it moves away from the ideal of decentralization. This tension shapes the evolution of blockchain technology.

Ultimately, the future of Web3 depends on where to draw the line between fast transaction processing, robust security, and true decentralization. As each project experiments with different approaches, the answer will gradually become clearer.
