Cointelegraph is following the event of a wholly new blockchain from inception to mainnet and past by way of its sequence, Contained in the Blockchain Developer’s Thoughts. In earlier elements, Andrew Levine of Koinos Group mentioned some of the challenges the staff has confronted since figuring out the important thing points they intend to resolve and outlined three of the “crises” which can be holding again blockchain adoption: upgradeability, scalability, and governance.
Blockchain testnets are an attention-grabbing topic as a result of they arrive in all sizes and shapes. So, on this put up, my purpose 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 influence on value.
The obvious place to begin is with the title: take a look atinternet. The aim of a testnet is to take a look at a internetwork. 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 wherein they’re launched dramatically impacts the notion, and influence, 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 present networks like Bitcoin and Ethereum, testnets serve two main features. The primary is that they’re a dwell surroundings wherein 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 surroundings that’s similar to the “most important chain” (e.g. Ethereum) wherein they’ll take a look at their code with successfully zero danger. Issues working on a testnet are anticipated to interrupt, and the tokens used are anticipated to be nugatory.
So, testnets are an surroundings that allows 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 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 shocked to see from my distinctive perspective is how generally DApp builders are conflated with blockchain builders. Sometimes, individuals who write sensible contracts aren’t blockchain builders, and blockchain builders typically spend little or no time writing sensible contracts.
Satirically, Koinos is throwing an enormous wrench on this distinction as a result of its complete 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 exhausting fork, but it surely additionally implies 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 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 need to develop updates in no matter programming language the blockchain is written in (C++, Rust, Haskell, and so forth.), and they’re engaged on a really giant and sophisticated system referred to as a “monolithic structure.” Inside monolithic architectures, altering any a part of the system can influence every other a part of the system, so the chance of creating adjustments is that a lot increased.
Blockchain builders additionally want a dwell surroundings with low stakes that they’ll use to check out their adjustments and see what breaks. Like utility builders, they need this surroundings to be as near the true community as potential, which implies that they need their code to work together with code that utility builders might be working 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 surroundings as potential, however with very low stakes. This allows each teams to enhance their merchandise and make them extra useful to their customers.
Now we are able to begin to see why testnets appear to have such an influence on token value. If we assume that value is a operate of worth, and that testnets assist builders enhance the worth of their merchandise, then value influence needs to 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 function of boosting their token value. Sadly, many individuals will see the testnet announcement and simply assume that one thing useful 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 present blockchains, which is that they create a secure area for utility builders to check their functions and for blockchain builders to check upgrades to the underlying platform. It will make it easier to perceive the opposite necessary context wherein 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. After all, since it’s new, there received’t be any functions working on it anyway. Now the state of affairs is extra one-sided. Nearly all of the individuals working with the codebase might be blockchain builders, and the purpose is to get the platform to a spot the place builders wish to really construct on it.
The primary requirement builders may have is that the platform is confirmed to be sufficiently secure, and that needs to be the prime directive behind the particular exams which can be run. Assuming builders are satisfied that the platform is sufficiently secure, then they’ll should be educated on the right way to use the platform. In different phrases, the testnet have to be regarded as an academic software that allows builders to achieve a deeper understanding of how they’ll 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 the right way to use it, they’ll inevitably discover locations the place the platform may very well be improved — necessary libraries may be wanted, or necessary documentation may 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.
Laptop networks have develop into a significant a part of our lives whether or not we understand it or not, and they’re solely growing in significance. Testnets are a essential step within the means of releasing new and revolutionary 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 wherein they’re launched, you are actually higher outfitted to guage particular testnet releases and whether or not they’re being designed and launched for the suitable causes.

Andrew Levine is the CEO of Koinos Group, the place he and the previous improvement staff 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 wholly new framework architected to offer builders the options they want as a way to ship the person experiences essential to unfold blockchain adoption to the lots.
Koinos Group just lately 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 sensible contracts on Koinos.
