Cointelegraph is following the event of a completely new blockchain from inception to mainnet and past by way of its collection, Contained in the Blockchain Developer’s Thoughts. In earlier elements, Andrew Levine of Koinos Group mentioned some of the challenges the workforce has confronted since figuring out the important thing points they intend to unravel and outlined three of the “crises” which are holding again blockchain adoption: upgradeability, scalability, and governance.
Blockchain testnets are an fascinating topic as a result of they arrive in all styles and sizes. So, on this submit, my objective is to leverage my inside expertise because the CEO of Koinos Group (builders of Koinos) to demystify testnets and maybe give some perception into why they appear to have such an impression on value.
The obvious place to start out is with the identify: take a look atweb. The aim of a testnet is to take a look at a webwork. At a really excessive stage, there are two “flavors” of testnet. The primary is a testnet that’s launched previous to a mainnet (most important community), and the second is a testnet that’s launched after a mainnet is already in operation. The features these serve are comparable, however the context through which they’re launched dramatically impacts the notion, and impression, of the discharge.
I’ll begin with the second type of testnet as a result of, in a means, that is the extra easy context. While you’re speaking about current networks like Bitcoin and Ethereum, testnets serve two major features. The primary is that they’re a dwell setting through which builders can take a look at their decentralized functions. Each good developer is aware of that there’s no such factor as excellent code, so testnets give builders an setting that’s similar to the “most important chain” (e.g. Ethereum) through which they’ll take a look at their code with successfully zero threat. Issues operating on a testnet are anticipated to interrupt, and the tokens used are anticipated to be nugatory.
So, testnets are an setting that permits decentralized software (DApp) builders to extend the worth of their functions (i.e., make their apps higher) exactly as a result of there isn’t a expectation of full performance or wealth creation. In a way, the worth of a testnet stems from its worthlessness.
DApp builders vs. blockchain builders
However testnets have a two-sided nature, which brings us to the second operate that testnets serve, and that operate is to the advantage of, not the DApp developer, however the platform developer (in our case, the blockchain developer). One factor I’ve been stunned to see from my distinctive perspective is how generally DApp builders are conflated with blockchain builders. Sometimes, individuals who write good contracts will not be blockchain builders, and blockchain builders typically spend little or no time writing good contracts.
Mockingly, Koinos is throwing an enormous wrench on this distinction as a result of its complete system is applied as good contracts! Since Koinos good contracts are upgradeable, because of this any function might be added to the blockchain with out a laborious fork, however it additionally signifies that the folks growing the blockchain (like members of the Koinos Group) are utilizing and growing the exact same toolchain and toolkit that builders will use to construct their DApps. However it is a function that’s completely distinctive to Koinos, so we are able to put that apart for the sake of this dialogue.
In each different blockchain, the blockchain builders should develop updates in no matter programming language the blockchain is written in (C++, Rust, Haskell, and many others.), and they’re engaged on a really massive and sophisticated system known as a “monolithic structure.” Inside monolithic architectures, altering any a part of the system can impression some other a part of the system, so the danger of creating modifications is that a lot larger.
Blockchain builders additionally want a dwell setting with low stakes that they’ll use to check out their modifications and see what breaks. Like software builders, they need this setting to be as near the true community as potential, which signifies that they need their code to work together with code that software builders might be operating as properly.
Two sides of testnets
This reveals the two-sided facet of testnets. They permit each the builders of functions and the builders of platforms to work together with each other and safely take a look at their code in as near a dwell setting as potential, however with very low stakes. This permits each teams to enhance their merchandise and make them extra precious to their customers.
Now we are able to begin to see why testnets appear to have such an impression on token value. If we assume that value is a operate of worth, and that testnets assist builders improve the worth of their merchandise, then value impression must be anticipated. The issue is that this correlation has led to a number of undesirable outcomes. Initiatives will usually launch a “testnet” that has no utility to builders for the only real goal of boosting their token value. Sadly, many individuals will see the testnet announcement and simply assume that one thing precious has been launched, and so the act may have the specified impact on the value.
Testnets earlier than mainnet
Up till now, I’ve been specializing in the utility of testnets within the context of current blockchains, which is that they create a protected house for software builders to check their functions and for blockchain builders to check upgrades to the underlying platform. This can enable you to perceive the opposite necessary context through which testnets are launched, which is previous to the discharge of the mainnet.
As soon as once more, testing is the first goal, however the focus is way extra on the system itself, because it has by no means earlier than been operational. In fact, since it’s new, there received’t be any functions operating on it anyway. Now the scenario is extra one-sided. Nearly all of the folks working with the codebase might be blockchain builders, and the objective is to get the platform to a spot the place builders wish to truly construct on it.
The primary requirement builders may have is that the platform is confirmed to be sufficiently protected, and that must be the prime directive behind the particular checks which are run. Assuming builders are satisfied that the platform is sufficiently protected, then they’ll should be educated on methods to use the platform. In different phrases, the testnet should be regarded as an academic software that permits builders to realize a deeper understanding of how they may be capable to use the platform whereas they’re additionally serving to to check the safety of the community.
Lastly, as they’re testing the community and studying methods to use it, they may inevitably discover locations the place the platform might be improved — necessary libraries is likely to be wanted, or necessary documentation is likely to be wanted to assist them perceive the system. This info is invaluable suggestions that the platform builders completely have to make use of to make the platform higher earlier than mainnet implementations are finalized.
Pc networks have turn into a serious a part of our lives whether or not we notice it or not, and they’re solely growing in significance. Testnets are a important step within the technique of releasing new and modern laptop networks that may add ever-increasing worth to our lives. Hopefully, by gaining a deeper understanding of the nuances of testnets and the necessary contexts through which they’re launched, you are actually higher geared up to judge particular testnet releases and whether or not they’re being designed and launched for the correct causes.

Andrew Levine is the CEO of Koinos Group, the place he and the previous improvement workforce behind the Steem blockchain construct blockchain-based options that empower folks to take possession and management over their digital selves. Their foundational product is Koinos, a high-performance blockchain constructed on a completely new framework architected to present builders the options they want with a purpose to ship the consumer experiences essential to unfold blockchain adoption to the plenty.
Koinos Group not too long ago launched model 2 of their testnet, which options stability enhancements, their mana fee-less transactions system and a contract improvement toolkit that may enable builders to construct and run good contracts on Koinos.
