Cointelegraph is following the event of a wholly new blockchain from inception to mainnet and past by its sequence, Contained in the Blockchain Developer’s Thoughts, written by Andrew Levine of Koinos Group.
We just lately launched the third and last model of the Koinos testnet, which is why I need to discuss one thing few initiatives like to speak about: Constructing blockchains is improvement hell. On this article, I’ll clarify why and the way different builders can keep away from getting caught in it.
At first blush, constructing a blockchain doesn’t sound so exhausting. A blockchain is only a mixture of well-established cryptographic primitives, which, when correctly carried out, enable for the development of a ledger containing a verifiable historical past of transactions by a community. The extra decentralized the community, the extra reliable the historical past.
Blockchain “frameworks”
In an effort to make constructing new blockchains simpler, different groups have launched blockchain “frameworks” that, in idea, ought to get rid of the necessity for builders to fret about constructing the blockchain itself in order that they’ll give attention to no matter distinctive options they need to construct into the blockchain. Cosmos, EOSIO and Polkadot’s Substrate are examples of such blockchain frameworks.
When our workforce stopped engaged on Steem (the world’s first fee-less blockchain), our unique intention was to leverage an current blockchain framework to construct a blockchain designed to be as accessible as potential. We had spent 4 years refining Steem’s fee-less design and figured that, by porting that resolution into an current blockchain framework, we may ship a blockchain that was much more accessible than every other blockchain in comparatively little time.

Really fee-less and general-purpose
However we have been shocked to seek out that not one of the current frameworks allowed us to create the type of really feeless person expertise we have been trying to carry to the market. We didn’t simply need to take away charges on a technical stage, we wished to empower builders to construct purposes that have been free to make use of. Additionally they lacked quite a lot of different options we believed have been required to ship an appropriate developer expertise.
The ability of a general-purpose blockchain stems not from the options the blockchain engineers construct into the blockchain however from the options that builders add to that blockchain as sensible contracts. That is doubly true for a blockchain framework that ought to actually be probably the most general-purpose blockchain conceivable because the complete concept is to permit folks to construct any type of blockchain they’ll think about. And but, the prevailing frameworks did not empower us, one of the skilled blockchain improvement groups, in our makes an attempt to construct the blockchain we wished to construct in a number of methods.
The prevailing frameworks not solely made it not possible for builders to create free-to-use purposes, however in addition they pressured builders to be taught new and sometimes troublesome programming languages and dramatically restricted the speed at which each purposes and the blockchain itself may enhance.

Liberating builders
We wished to construct a blockchain that may free builders to construct insanely nice purposes that peculiar folks would love to make use of. That allowed the builders to work within the programming languages they already knew and beloved (what we name “common language assist”); that allowed their purposes (and the blockchain itself) to quickly evolve; and, most significantly, it allowed them to construct purposes that have been free to make use of.
However to be able to construct that blockchain we first wanted a very general-purpose blockchain framework that may not solely enable us to construct the blockchain of our desires however as a pure consequence of being probably the most general-purpose framework conceivable, ought to enable anybody to construct the blockchain of their desires.
Koinos is that final general-purpose blockchain framework that can function the inspiration for the last word feeless layer 1: Koinos mainnet. The Koinos Blockchain Framework (KBF) is designed to be the best blockchain conceivable, containing solely these cryptographic primitives essential to assemble a blockchain and the proper “system calls” to permit for the widest vary of behaviors to be added in-band (and not using a exhausting fork) by the importing of a wise contract.
Infinite upgradeability
The good thing about this design is infinite upgradeability, however the price is that it makes getting the system calls proper all of the extra necessary. Lacking a system name or designing it incorrectly would imply having to take care of an in any other case avoidable exhausting fork. As a result of exhausting forks are so time-consuming, political and disruptive, they’re the one largest issue limiting a blockchain’s potential to enhance itself, which is in the end felt by each single developer whose utility is constructed on such a platform.
Now we are able to see how each utility and blockchain builders can get trapped in improvement hell: working in programming languages they aren’t snug with, on platforms that power them to include charges and that enhance at a snail’s tempo. Beneath these circumstances, even minor adjustments have extremely excessive stakes, and we haven’t even factored in these situations the place there are tens of millions, generally billions, of {dollars} in danger.
That’s improvement hell. Because the core improvement workforce behind the Steem blockchain that needed to oversee 23 exhausting forks, we all know this terrain higher than virtually anybody else, which is why we have been so dedicated to banishing it, effectively … to hell.
Constructing the Koinos Blockchain Framework from scratch with a wholly novel microservice structure and getting it to the purpose the place we may launch variations 1 and a couple of of the testnet have been extremely difficult. However integrating the suggestions we bought from these testnets, fixing the bugs they uncovered, and finalizing the all-important system calls have been an entire different stage. However we went by that improvement hell with the hopes of creating it in order that others gained’t ever should.
Harbinger
Testnet v3 is, subsequently, greater than “simply one other” model of the testnet. It’s the last model of the Koinos Blockchain Framework, which is why we’ll now seek advice from the testnet, not by a model quantity, however by the title: Harbinger. It’s the end result of practically two years of working, figuring out and implementing all the mandatory system calls wanted to offer blockchain builders the last word stage of freedom and permit their utility builders to profit from a platform that’s enhancing at a extra fast price than every other blockchain on the market.
After all, everytime you’re making an attempt to unravel a extremely necessary drawback, some stage of improvement hell is inevitable. You simply need to just remember to don’t undertake applied sciences that increase the stakes unnecessarily and that the objective you’re striving for is price the price.
For us, that objective is just not solely sparing blockchain builders (together with ourselves) from numerous hours spent in developer hell but in addition leveraging this new know-how to construct Koinos mainnet: the last word feeless layer 1 for empowering builders to construct insanely nice blockchain-based purposes.
No extra improvement hell
The KBF goals to get rid of improvement hell by permitting builders to construct any blockchain they’ll think about just by writing sensible contracts, which is infinitely simpler than working within the blockchain code itself. And that’s precisely the place we discover ourselves in now. Whereas growing the blockchain framework was extremely difficult, now that it’s over, all that’s wanted to finish Koinos mainnet is simply two sensible contracts: one for our proof-of-burn consensus algorithm and the opposite for governance.
Not solely is writing sensible contracts far less complicated than blockchain improvement, however this additionally implies that blockchain builders now get to make the most of the ever-expanding instruments which might be accessible to sensible contract builders just like the AssemblyScript SDK one in every of our group members constructed. AssemblyScript doesn’t simply produce much more environment friendly sensible contracts than these written in C++ (that was a shock), it makes sensible contract improvement accessible to JavaScript builders.
For the reason that KBF turns any sensible contract developer into a possible blockchain developer, which means that growing customized blockchains will now be accessible to JavaScript builders with much more languages to come back, corresponding to Rust.
In case you’re enthusiastic about working Harbinger, we’ve made it insanely simple to run a node so that you may be up and working in underneath 5 minutes.
