The metrics used to measure outcomes could be deceptive when evaluating blockchain efficiency. As extra blockchain networks emerge, the general public wants clear, efficiency-focused metrics, fairly than exaggerated claims, to distinguish between them.
In a dialog with BeInCrypto, Taraxa Co-Founder Steven Pu defined that it’s changing into more and more troublesome to check blockchain efficiency precisely as a result of many reported metrics depend on overly optimistic assumptions fairly than evidence-based outcomes. To fight this wave of misrepresentation, Pu proposes a brand new metric, which he calls TPS/$.
Why Does the Business Lack Dependable Benchmarks?
The necessity for clear differentiation is rising with the growing variety of Layer-1 blockchain networks. As numerous builders promote the pace and effectivity of their blockchains, counting on metrics that distinguish their efficiency turns into indispensable.
Nevertheless, the {industry} nonetheless lacks dependable benchmarks for real-world effectivity, as an alternative counting on sporadic sentimental waves of hype-driven recognition. In line with Pu, deceptive efficiency figures at present saturate the market, obscuring true capabilities.
“It’s straightforward for opportunists to take benefit by driving up over-simplified and exaggerated narratives to revenue themselves. Each single conceivable technical idea and metric has at one time or one other been used to hype up many tasks that don’t actually deserve them: TPS, finality latency, modularity, community node rely, execution pace, parallelization, bandwidth utilization, EVM-compatibility, EVM-incompatibility, and so forth.,” Pu advised BeInCrypto.
Pu targeted on how some tasks exploit TPS metrics, utilizing them as advertising techniques to make blockchain efficiency sound extra interesting than it could be underneath real-world situations.
Analyzing the Deceptive Nature of TPS
Transactions per second, extra generally referred to as TPS, is a metric that refers back to the common or sustained variety of transactions {that a} blockchain community can course of and finalize per second underneath regular working situations.
Nevertheless, it typically misleadingly hypes tasks, providing a skewed view of total efficiency.
“Decentralized networks are complicated programs that have to be thought of as an entire, and within the context of their use instances. However the market has this horrible behavior of over-simplifying and over-selling one particular metric or side of a venture, whereas ignoring the complete. Maybe a extremely centralized, high-TPS community does have its makes use of in the fitting situations with particular belief fashions, however the market actually has no urge for food for such nuanced descriptions,” Pu defined.
Pu signifies that blockchain tasks with excessive claims on single metrics like TPS might have compromised decentralization, safety, and accuracy.
“Take TPS, for instance. This one metric masks quite a few different points of the community, for instance, how was the TPS achieved? What was sacrificed within the course of? If I’ve 1 node, operating a WASM JIT VM, name {that a} community, that will get you a couple of hundred thousand TPS proper off the bat. I then make 1000 copies of that machine and name it sharding, now you begin to get into the a whole lot of thousands and thousands of ‘TPS’. Add in unrealistic assumptions comparable to non-conflict, and you assume you’ll be able to parallelize all transactions, then you will get “TPS” into the billions. It’s not that TPS is a nasty metric, you simply can’t take a look at any metric in isolation as a result of there’s a lot hidden info behind the numbers,” he added.
The Taraxa Co-founder revealed the extent of those inflated metrics in a current report.
The Important Discrepancy Between Theoretical and Actual-World TPS
Pu sought to show his level by figuring out the distinction between the utmost historic TPS realized on a blockchain’s mainnet and the utmost theoretical TPS.
Of the 22 permissionless and single-shard networks noticed, Pu discovered that, on common, there was a 20-fold hole between concept and actuality. In different phrases, the theoretical metric was 20 occasions larger than the utmost noticed mainnet TPS.

“Metric overestimations (comparable to within the case of TPS) are a response to the extremely speculative and narrative-driven crypto market. Everybody desires to place their venture and applied sciences in the absolute best mild, so that they give you theoretical estimates, or conduct exams with wildly unrealistic assumptions, to reach at inflated metrics. It’s dishonest promoting. Nothing extra, nothing much less,” Pu advised BeInCrypto.
Seeking to counter these exaggerated metrics, Pu developed his personal efficiency measure.
Introducing TPS/$: A Extra Balanced Metric?
Pu and his workforce developed the next: TPS realized on mainnet / month-to-month $ value of a single validator node, or TPS/$ for brief, to meet the necessity for higher efficiency metrics.
This metric assesses efficiency based mostly on verifiable TPS achieved on a community’s reside mainnet whereas additionally contemplating {hardware} effectivity.
The numerous 20-fold hole between theoretical and precise throughput satisfied Pu to exclude metrics based mostly solely on assumptions or lab situations. He additionally aimed for instance how some blockchain tasks inflate efficiency metrics by counting on expensive infrastructure.
“Revealed community efficiency claims are sometimes inflated by extraordinarily costly {hardware}. That is very true for networks with extremely centralized consensus mechanisms, the place the throughput bottleneck shifts away from networking latency and into single-machine {hardware} efficiency. Requiring extraordinarily costly {hardware} for validators not solely betrays a centralized consensus algorithm and inefficient engineering, it additionally prevents the overwhelming majority of the world from doubtlessly collaborating in consensus by pricing them out,” Pu defined.
Pu’s workforce positioned every community’s minimal validator {hardware} necessities to find out the price per validator node. They later estimated their month-to-month value, paying explicit consideration to their relative sizing when used to compute the TPS per greenback ratios.
“So the TPS/$ metric tries to appropriate two of the maybe most egregious classes of misinformation, by forcing the TPS efficiency to be on mainnet, and revealing the inherent tradeoffs of extraordinarily costly {hardware},” Pu added.
Pu confused contemplating two easy, identifiable traits: whether or not a community is permissionless and single-sharded.
Permissioned vs. Permissionless Networks: Which Fosters Decentralization?
A blockchain’s diploma of safety could be unveiled by whether or not it operates underneath a permissioned or permissionless community.
Permissioned blockchains check with closed networks the place entry and participation are restricted to a predefined group of customers, requiring permission from a government or trusted group to hitch. In permissionless blockchains, anybody is allowed to take part.
In line with Pu, the previous mannequin is at odds with the philosophy of decentralization.
“A permissioned community, the place community validation membership is managed by a single entity, or if there’s only a single entity (each Layer-2s), is one other glorious metric. This tells you whether or not or not the community is certainly decentralized. A trademark of decentralization is its skill to bridge belief gaps. Take decentralization away, then the community is nothing greater than a cloud service,” Pu advised BeInCrypto.
Consideration to those metrics will show important over time, as networks with centralized authorities are usually extra weak to sure weaknesses.
“In the long run, what we actually want is a battery of standardized assault vectors for L1 infrastructure that may assist to disclose weaknesses and tradeoffs for any given architectural design. A lot of the issues in at the moment’s mainstream L1 are that they make unreasonable sacrifices in safety and decentralization. These traits are invisible and intensely laborious to look at, till a catastrophe strikes. My hope is that because the {industry} matures, such a battery of exams will start to organically emerge into an industry-wide normal,” Pu added.
In the meantime, understanding whether or not a community employs state-sharding versus sustaining a single, sharded state reveals how unified its knowledge administration is.
State-Sharding vs. Single-State: Understanding Knowledge Unity
In blockchain efficiency, latency refers back to the time delay between submitting a transaction to the community, confirming it, and together with it in a block on the blockchain. It measures how lengthy it takes for a transaction to be processed and grow to be a everlasting a part of the distributed ledger.
Figuring out whether or not a community employs state-sharding or a single-sharded state can reveal a lot about its latency effectivity.
State-sharded networks divide the blockchain’s knowledge into a number of impartial components known as shards. Every shard operates considerably independently and doesn’t have direct, real-time entry to the whole state of the complete community.
Against this, a non-state-sharded community has a single, shared state throughout the complete community. All nodes can entry and course of the identical full knowledge set on this case.
Pu famous that state-sharded networks purpose to extend storage and transaction capability. Nevertheless, they typically face longer finality latencies as a consequence of a have to course of transactions throughout a number of impartial shards.
He added that many tasks adopting a sharding strategy inflate throughput by merely replicating their community fairly than constructing a very built-in and scalable structure.
“A state-sharded community that doesn’t share state, is just making unconnected copies of a community. If I take a L1 community and simply make 1000 copies of it operating independently, it’s clearly dishonest to assert that I can add up all of the throughput throughout the copies collectively and characterize it as a single community. There are architectures that truly synchronize the states in addition to shuffle the validators throughout shards, however most of the time, tasks making outlandish claims on throughput are simply making impartial copies,” Pu stated.
Based mostly on his analysis into the effectivity of blockchain metrics, Pu highlighted the necessity for basic shifts in how tasks are evaluated, funded, and in the end succeed.
What Elementary Shifts Does Blockchain Analysis Want?
Pu’s insights current a notable different in a Layer-1 blockchain area the place deceptive efficiency metrics more and more compete for consideration. Dependable and efficient benchmarks are important to counter these false representations.
“You solely know what you’ll be able to measure, and proper now in crypto, the numbers look extra like hype-narratives than goal measurements. Having standardized, clear measurements permits easy comparisons throughout product choices so builders and customers perceive what it is that they’re utilizing, and what tradeoffs they’re making. This can be a hallmark of any mature {industry}, and we nonetheless have an extended approach to go in crypto,” Pu concluded.
Adopting standardized and clear benchmarks will foster knowledgeable decision-making and drive real progress past merely promotional claims because the {industry} matures.
