The metrics used to measure outcomes will be deceptive when evaluating blockchain efficiency. As extra blockchain networks emerge, the general public wants clear, efficiency-focused metrics, relatively 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 tough to check blockchain efficiency precisely as a result of many reported metrics depend on overly optimistic assumptions relatively 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 rising variety of Layer-1 blockchain networks. As varied builders promote the velocity and effectivity of their blockchains, counting on metrics that distinguish their efficiency turns into indispensable.
Nonetheless, the {industry} nonetheless lacks dependable benchmarks for real-world effectivity, as a substitute counting on sporadic sentimental waves of hype-driven recognition. In keeping with Pu, deceptive efficiency figures at present saturate the market, obscuring true capabilities.
“It’s simple 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 initiatives that don’t actually deserve them: TPS, finality latency, modularity, community node depend, execution velocity, parallelization, bandwidth utilization, EVM-compatibility, EVM-incompatibility, and so on.,” Pu advised BeInCrypto.
Pu centered on how some initiatives exploit TPS metrics, utilizing them as advertising and marketing techniques to make blockchain efficiency sound extra interesting than it is likely to be underneath real-world situations.
Inspecting the Deceptive Nature of TPS
Transactions per second, extra generally generally known 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.
Nonetheless, it usually misleadingly hypes initiatives, providing a skewed view of total efficiency.
“Decentralized networks are advanced techniques that have to be thought-about 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 mission, whereas ignoring the entire. Maybe a extremely centralized, high-TPS community does have its makes use of in the best situations with particular belief fashions, however the market actually has no urge for food for such nuanced descriptions,” Pu defined.
Pu signifies that blockchain initiatives 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 elements 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 number 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 tons of of hundreds of thousands of ‘TPS’. Add in unrealistic assumptions akin to non-conflict, and you assume you may parallelize all transactions, then you may 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 Vital 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 principle and actuality. In different phrases, the theoretical metric was 20 occasions larger than the utmost noticed mainnet TPS.

“Metric overestimations (akin to within the case of TPS) are a response to the extremely speculative and narrative-driven crypto market. Everybody needs to place their mission and applied sciences in the absolute best mild, in order that they provide you with theoretical estimates, or conduct assessments with wildly unrealistic assumptions, to reach at inflated metrics. It’s dishonest promoting. Nothing extra, nothing much less,” Pu advised BeInCrypto.
Trying to counter these exaggerated metrics, Pu developed his personal efficiency measure.
Introducing TPS/$: A Extra Balanced Metric?
Pu and his group developed the next: TPS realized on mainnet / month-to-month $ value of a single validator node, or TPS/$ for brief, to satisfy the necessity for higher efficiency metrics.
This metric assesses efficiency based mostly on verifiable TPS achieved on a community’s stay 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 as an example how some blockchain initiatives inflate efficiency metrics by counting on expensive infrastructure.
“Printed 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 group 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 specific consideration to their relative sizing when used to compute the TPS per greenback ratios.
“So the TPS/$ metric tries to right 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 will be unveiled by whether or not it operates underneath a permissioned or permissionless community.
Permissioned blockchains seek advice from closed networks the place entry and participation are restricted to a predefined group of customers, requiring permission from a government or trusted group to affix. In permissionless blockchains, anybody is allowed to take part.
In keeping 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. An indicator of decentralization is its capability 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 very important over time, as networks with centralized authorities are typically 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 right now’s mainstream L1 are that they make unreasonable sacrifices in safety and decentralization. These traits are invisible and very onerous to look at, till a catastrophe strikes. My hope is that because the {industry} matures, such a battery of assessments 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 information administration is.
State-Sharding vs. Single-State: Understanding Information 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 develop into 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 information into a number of impartial components referred to as shards. Every shard operates considerably independently and doesn’t have direct, real-time entry to the entire state of your complete community.
Against this, a non-state-sharded community has a single, shared state throughout your complete community. All nodes can entry and course of the identical full information set on this case.
Pu famous that state-sharded networks goal to extend storage and transaction capability. Nonetheless, they usually face longer finality latencies attributable to a must course of transactions throughout a number of impartial shards.
He added that many initiatives adopting a sharding strategy inflate throughput by merely replicating their community relatively than constructing a really 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 say that I can add up all of the throughput throughout the copies collectively and symbolize 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, initiatives making outlandish claims on throughput are simply making impartial copies,” Pu stated.
Primarily based on his analysis into the effectivity of blockchain metrics, Pu highlighted the necessity for basic shifts in how initiatives are evaluated, funded, and finally succeed.
What Elementary Shifts Does Blockchain Analysis Want?
Pu’s insights current a notable different in a Layer-1 blockchain house 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 may 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. It is a hallmark of any mature {industry}, and we nonetheless have an extended technique 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.
