Blockchain Velocity: The Hidden Truth Behind Collapsing TPS Numbers

The celebrated TPS (Transactions Per Second) speeds of blockchain technology, once a hallmark of its promise, are now experiencing a dramatic decline in real-world usage. This phenomenon is not merely a technical limitation but a complex interplay of factors including network composition, transaction types, and user behavior patterns. Notably, during periods of concentrated large-scale transactions or when executing specific smart contracts, the network becomes congested, leading to a sharp drop in TPS. FireMarkets’ analysis suggests that this TPS collapse isn’t just a technical issue, but also a critical indicator of the blockchain ecosystem’s maturity and the need for improvements in user experience.

Delving into the Root Causes of TPS Collapse

The TPS of a blockchain network isn’t simply a measure of node processing speed; it’s profoundly influenced by the complexity of transactions, data size, and the behavior patterns of network participants. For instance, a simple transfer transaction requires a relatively low TPS, but a transaction involving complex smart contract execution demands significantly more computational resources, leading to a sharp decline in TPS. Furthermore, instability in network participant connectivity or their connection quality can degrade processing speeds, resulting in lower TPS. Notably, in 2026, the rapid growth of DeFi (Decentralized Finance) services has intensified this trend, with the frequency of smart contract execution increasing, exacerbating network congestion and driving down TPS. FireMarkets’ data analysis reveals a clear trend: specific DeFi protocols exhibit exponential TPS decreases as transaction volume grows, highlighting the severity of scalability issues.
