In the rapidly evolving world of blockchain technology, developers often promote impressive transaction speeds, claiming their platforms can handle thousands of transactions per second (TPS). However, a recent study reveals that these claims may be significantly overstated, with many blockchains processing less than five percent of their advertised maximum throughput. This discrepancy raises questions about the reliability of the metrics used to assess blockchain performance and the implications for investors and users alike.
Theoretical Maximum vs. Actual Throughput
The study highlights the stark contrast between theoretical maximum TPS and actual observed throughput across various blockchain networks. For instance, while one platform claims a theoretical maximum of 65,000 TPS, research indicates that its maximum observed throughput is closer to 4,000 TPS. This pattern is not unique; many blockchain platforms exhibit similar overstatements, with the average blockchain processing less than one-twentieth of its stated maximum throughput.
In extreme cases, the difference is even more pronounced, with a theoretical maximum TPS over 100 times higher than its observed throughput of 471 TPS. Variations in reported TPS figures can be attributed to different methodologies used to calculate observable blockchain throughput. For example, on a specific date, one source recorded a TPS of less than 900, while other sources reported figures of 4,200 and 4,400, respectively.
Discrepancies in Transaction Reporting
These discrepancies can often be explained by the inclusion of vote transactions, which, while technically classified as transactions, do not represent the actual movement of tokens or user data. When excluding these vote transactions, the highest recorded TPS over a ten-block span was 2,909, a far cry from the theoretical maximum. The study also highlights that the theoretical maximums presented by blockchain developers often rely on unrealistic hardware setups that would not be practical for everyday use.
This raises concerns about the validity of these claims, as they may mislead investors and users regarding the true capabilities of the technology. Criticism has been directed at the maximum theoretical TPS of certain platforms, arguing that it should be significantly lower than the figures claimed by their developers. In one case, the maximum theoretical TPS was asserted to be just 18, leading to a staggering 26.5 times misrepresentation of its capabilities.
Evaluating Blockchain Speed
When evaluating blockchain speed, it is essential to consider not only the theoretical maximums but also the practical aspects of hardware efficiency and cost. Theoretical TPS figures often assume ideal conditions that are not reflective of real-world scenarios. An alternative metric proposed is realized TPS per dollar spent on validator nodes, which provides a more accurate picture of a blockchain’s efficiency and cost-effectiveness.
In this regard, certain platforms outperform some of the faster blockchains, which struggle with efficiency despite their high theoretical speeds. The current landscape of Web3 adoption suggests that the focus on theoretical maximums may be misplaced. Even established payment networks rarely exceed a few thousand transactions per second, indicating that the demand required to achieve the lofty TPS figures promised by some blockchains is unlikely to materialize in the near future.
Future Considerations for Blockchain Development
As the industry matures, it may be more prudent for developers to prioritize meeting realistic TPS demands in a cost-effective manner rather than chasing unattainable theoretical maximums. As the blockchain ecosystem continues to evolve, the conversation around throughput metrics will likely intensify. Investors and users must remain vigilant and critical of the claims made by blockchain developers, particularly regarding transaction speeds.
The findings from the study serve as a reminder that the blockchain space is still in its infancy, and many platforms have yet to demonstrate their capabilities in real-world scenarios. The implications of these discrepancies extend beyond mere marketing tactics; they can influence investment decisions and the overall perception of blockchain technology.
Importance of Transparency and Accountability
As the industry strives for greater transparency and accountability, it is crucial for developers to provide accurate and realistic assessments of their platforms’ capabilities. This shift could foster greater trust among users and investors, ultimately contributing to the long-term success and adoption of blockchain technology in various sectors.
