Blockchain transactions per second (TPS) figures are frequently used as a performance metric, but they often fail to reflect real-world scalability, according to Carter Feldman, founder of Psy Protocol. Feldman highlights that many TPS benchmarks are conducted under ideal conditions, such as with a single node, which do not account for the complexities of decentralized verification and relay across networks. Feldman argues that while high TPS numbers suggest a network's capacity to handle more transactions, they often ignore the increased burden on nodes, which can compromise decentralization. He suggests that zero-knowledge (ZK) technology could alleviate some of these scaling challenges by allowing transaction validity to be proven without each node reprocessing the data. However, implementing ZK technology is complex and requires significant computational resources. Despite the challenges, TPS remains a useful benchmark when measured in production environments where transactions are fully processed and verified. Feldman emphasizes that economic indicators like transaction fees may provide a more accurate reflection of network health and demand than raw TPS figures alone.
