How to avoid development hell

Cointelegraph is following the event of a completely new blockchain from inception to mainnet and past by means of its collection, Contained in the Blockchain Developer’s Thoughts, written by Andrew Levine of Koinos Group.

We lately launched the third and ultimate model of the Koinos testnet, which is why I wish to discuss one thing few initiatives like to speak about: Constructing blockchains is growth 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 laborious. A blockchain is only a mixture of well-established cryptographic primitives, which, when correctly applied, permit 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 remove the necessity for builders to fret about constructing the blockchain itself in order that they’ll give attention to no matter distinctive options they wish to construct into the blockchain. Cosmos, EOSIO and Polkadot’s Substrate are examples of such blockchain frameworks.

When our crew 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 attainable. We had spent 4 years refining Steem’s fee-less design and figured that, by porting that answer into an current blockchain framework, we may ship a blockchain that was way more accessible than another blockchain in comparatively little time.

Actually fee-less and general-purpose

However we have been stunned to seek out that not one of the current frameworks allowed us to create the sort of really feeless consumer expertise we have been trying to deliver to the market. We didn’t simply wish to take away charges on a technical stage, we wished to empower builders to construct purposes that have been free to make use of. In addition they lacked plenty of different options we believed have been required to ship a suitable developer expertise.

The facility 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 good contracts. That is doubly true for a blockchain framework that ought to actually be essentially the most general-purpose blockchain conceivable for the reason that entire thought is to permit individuals to construct any sort of blockchain they’ll think about. And but, the prevailing frameworks didn’t empower us, probably the most skilled blockchain growth groups, in our makes an attempt to construct the blockchain we wished to construct in a number of methods.

The present frameworks not solely made it unattainable for builders to create free-to-use purposes, however additionally they compelled builders to study new and sometimes tough 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 atypical individuals would love to make use of. That allowed the builders to work within the programming languages they already knew and liked (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 as a way to construct that blockchain we first wanted a really general-purpose blockchain framework that may not solely permit us to construct the blockchain of our desires however as a pure consequence of being essentially the most general-purpose framework conceivable, ought to permit anybody to construct the blockchain of their desires.

Koinos is that final general-purpose blockchain framework that can function the muse for the final word feeless layer 1: Koinos mainnet. The Koinos Blockchain Framework (KBF) is designed to be the only blockchain conceivable, containing solely these cryptographic primitives essential to assemble a blockchain and the best “system calls” to permit for the widest vary of behaviors to be added in-band (and not using a laborious fork) by means of the importing of a sensible contract.

Infinite upgradeability

The good thing about this design is infinite upgradeability, however the fee 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 laborious fork. As a result of laborious forks are so time-consuming, political and disruptive, they’re the only largest issue limiting a blockchain’s capacity to enhance itself, which is in the end felt by each single developer whose utility is constructed on such a platform.

Now we will see how each utility and blockchain builders can get trapped in growth hell: working in programming languages they aren’t snug with, on platforms that drive 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 thousands and thousands, generally billions, of {dollars} in danger.

That’s growth hell. Because the core growth crew behind the Steem blockchain that needed to oversee 23 laborious forks, we all know this terrain higher than virtually anybody else, which is why we have been so dedicated to banishing it, nicely … to hell.

Constructing the Koinos Blockchain Framework from scratch with a completely novel microservice structure and getting it to the purpose the place we may launch variations 1 and a pair of of the testnet have been extremely difficult. However integrating the suggestions we obtained from these testnets, fixing the bugs they uncovered, and finalizing the all-important system calls have been a complete different stage. However we went by means of that growth hell with the hopes of constructing it in order that others received’t ever need to.

Harbinger

Testnet v3 is, due to this fact, greater than “simply one other” model of the testnet. It’s the ultimate model of the Koinos Blockchain Framework, which is why we’ll now discuss with the testnet, not by a model quantity, however by the identify: Harbinger. It’s the fruits of practically two years of working, figuring out and implementing all the mandatory system calls wanted to provide blockchain builders the final word stage of freedom and permit their utility builders to learn from a platform that’s bettering at a extra speedy price than another blockchain on the market.

After all, everytime you’re attempting to unravel a extremely necessary downside, some stage of growth hell is inevitable. You simply wish to just remember to don’t undertake applied sciences that increase the stakes unnecessarily and that the purpose you’re striving for is price the fee.

For us, that purpose shouldn’t be solely sparing blockchain builders (together with ourselves) from numerous hours spent in developer hell but additionally leveraging this new know-how to construct Koinos mainnet: the final word feeless layer 1 for empowering builders to construct insanely nice blockchain-based purposes.

No extra growth hell

The KBF goals to remove growth hell by permitting builders to construct any blockchain they’ll think about just by writing good contracts, which is infinitely simpler than working within the blockchain code itself. And that’s precisely the place we discover ourselves in now. Whereas creating the blockchain framework was extremely difficult, now that it’s over, all that’s wanted to finish Koinos mainnet is simply two good contracts: one for our proof-of-burn consensus algorithm and the opposite for governance.

Not solely is writing good contracts far less complicated than blockchain growth, however this additionally implies that blockchain builders now get to make the most of the ever-expanding instruments which are accessible to good contract builders just like the AssemblyScript SDK considered one of our group members constructed. AssemblyScript doesn’t simply produce way more environment friendly good contracts than these written in C++ (that was a shock), it makes good contract growth accessible to JavaScript builders.

For the reason that KBF turns any good contract developer into a possible blockchain developer, which means creating customized blockchains will now be accessible to JavaScript builders with much more languages to return, similar to Rust.

When you’re keen on operating Harbinger, we’ve made it insanely straightforward to run a node so that you could be up and operating in below 5 minutes.
