Cointelegraph is following the event of a completely new blockchain from inception to mainnet and past via its collection, Contained in the Blockchain Developer’s Thoughts. In earlier components, Andrew Levine of Koinos Group mentioned some of the challenges the crew 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 publish, 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 worth.
The obvious place to start out is with the identify: checkweb. The aim of a testnet is to check a webwork. At a really excessive degree, 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 related, however the context through which they’re launched dramatically impacts the notion, and impression, of the discharge.
I’ll begin with the second sort of testnet as a result of, in a manner, that is the extra simple context. If you’re speaking about current networks like Bitcoin and Ethereum, testnets serve two major features. The primary is that they’re a reside surroundings through which builders can check their decentralized functions. Each good developer is aware of that there’s no such factor as excellent code, so testnets give builders an surroundings that’s similar to the “most important chain” (e.g. Ethereum) through which they’ll check 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 surroundings that permits decentralized utility (DApp) builders to extend the worth of their functions (i.e., make their apps higher) exactly as a result of there isn’t any 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 sensible contracts should not blockchain builders, and blockchain builders typically spend little or no time writing sensible contracts.
Mockingly, Koinos is throwing an enormous wrench on this distinction as a result of its whole system is carried out as sensible contracts! Since Koinos sensible contracts are upgradeable, which means that any function may be added to the blockchain with no onerous fork, however it additionally signifies that the individuals 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 this can be 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 complex system referred to as a “monolithic structure.” Inside monolithic architectures, altering any a part of the system can impression every other a part of the system, so the danger of constructing modifications is that a lot larger.
Blockchain builders additionally want a reside surroundings with low stakes that they’ll use to check out their modifications and see what breaks. Like utility builders, they need this surroundings to be as near the actual community as attainable, which signifies that they need their code to work together with code that utility builders shall 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 check their code in as near a reside surroundings as attainable, however with very low stakes. This permits each teams to enhance their merchandise and make them extra helpful to their customers.
Now we are able to begin to see why testnets appear to have such an impression on token worth. If we assume that worth is a operate of worth, and that testnets assist builders improve the worth of their merchandise, then worth impression ought to be anticipated. The issue is that this correlation has led to a number of undesirable outcomes. Tasks will typically launch a “testnet” that has no utility to builders for the only real goal of boosting their token worth. Sadly, many individuals will see the testnet announcement and simply assume that one thing helpful has been launched, and so the act can have the specified impact on the worth.
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 area for utility builders to check their functions and for blockchain builders to check upgrades to the underlying platform. This may assist you perceive the opposite essential 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 much extra on the system itself, because it has by no means earlier than been operational. In fact, since it’s new, there gained’t be any functions operating on it anyway. Now the scenario is extra one-sided. The vast majority of the individuals working with the codebase shall be blockchain builders, and the objective is to get the platform to a spot the place builders need to truly construct on it.
The primary requirement builders can have is that the platform is confirmed to be sufficiently protected, and that ought to be the prime directive behind the particular checks which are run. Assuming builders are satisfied that the platform is sufficiently protected, then they’ll must be educated on tips on how to use the platform. In different phrases, the testnet should be considered an academic instrument that permits builders to achieve a deeper understanding of how they are going to have the ability 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 tips on how to use it, they are going to inevitably discover locations the place the platform could possibly be improved — essential libraries is perhaps wanted, or essential documentation is perhaps wanted to assist them perceive the system. This data 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 understand it or not, and they’re solely rising in significance. Testnets are a essential step within the means of releasing new and modern pc networks that may add ever-increasing worth to our lives. Hopefully, by gaining a deeper understanding of the nuances of testnets and the essential contexts through which they’re launched, you are actually higher outfitted to judge particular testnet releases and whether or not they’re being designed and launched for the appropriate causes.

Andrew Levine is the CEO of Koinos Group, the place he and the previous growth crew behind the Steem blockchain construct blockchain-based options that empower individuals 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 provide builders the options they want with a view to ship the person 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 growth toolkit that may enable builders to construct and run sensible contracts on Koinos.
