How to avoid development hell

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

We not too long ago launched the third and closing model of the Koinos testnet, which is why I wish to speak about one thing few tasks 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 exhausting. 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 concept, ought to remove the necessity for builders to fret about constructing the blockchain itself in order that they’ll deal with 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 group stopped engaged on Steem (the world’s first fee-less blockchain), our authentic 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 might ship a blockchain that was much 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 form of actually feeless consumer expertise we have been trying to carry to the market. We didn’t simply wish to take away charges on a technical degree, we needed to empower builders to construct purposes that have been free to make use of. Additionally they lacked plenty 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 good contracts. That is doubly true for a blockchain framework that ought to actually be probably the most general-purpose blockchain conceivable for the reason that entire concept is to permit folks to construct any form of blockchain they’ll think about. And but, the present frameworks didn’t empower us, some of the skilled blockchain growth groups, in our makes an attempt to construct the blockchain we needed to construct in a number of methods.

The present frameworks not solely made it not possible for builders to create free-to-use purposes, however additionally they compelled builders to study new and infrequently troublesome programming languages and dramatically restricted the speed at which each purposes and the blockchain itself might enhance.

Liberating builders

We needed to construct a blockchain that might free builders to construct insanely nice purposes that abnormal folks would love to make use of. That allowed the builders to work within the programming languages they already knew and cherished (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 in an effort to construct that blockchain we first wanted a very general-purpose blockchain framework that might not solely permit us to construct the blockchain of our goals however as a pure consequence of being probably the most general-purpose framework conceivable, ought to permit anybody to construct the blockchain of their goals.

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 (with out a exhausting fork) by way of the importing of a wise contract.

Infinite upgradeability

The advantage of this design is infinite upgradeability, however the associated fee is that it makes getting the system calls proper all of the extra vital. Lacking a system name or designing it incorrectly would imply having to cope with an in any other case avoidable exhausting fork. As a result of exhausting forks are so time-consuming, political and disruptive, they’re the only greatest issue limiting a blockchain’s capability 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 pressure them to include charges and that enhance at a snail’s tempo. Beneath these circumstances, even minor modifications have extremely excessive stakes, and we haven’t even factored in these situations the place there are hundreds of thousands, generally billions, of {dollars} in danger.

That’s growth hell. Because the core growth group behind the Steem blockchain that needed to oversee 23 exhausting forks, we all know this terrain higher than nearly 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 wholly novel microservice structure and getting it to the purpose the place we might launch variations 1 and a couple 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 degree. However we went by way of that growth hell with the hopes of constructing it in order that others received’t ever must.

Harbinger

Testnet v3 is, due to this fact, greater than “simply one other” model of the testnet. It’s the closing model of the Koinos Blockchain Framework, which is why we are going to now discuss with 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 provide blockchain builders the last word degree of freedom and permit their utility builders to profit from a platform that’s bettering at a extra speedy charge than another blockchain on the market.

In fact, everytime you’re attempting to unravel a extremely vital downside, some degree 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 objective you’re striving for is value the associated fee.

For us, that objective will not be 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 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 growing 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 might be out there to good contract builders just like the AssemblyScript SDK considered one of our neighborhood members constructed. AssemblyScript doesn’t simply produce much 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 growing customized blockchains will now be accessible to JavaScript builders with much more languages to return, akin to Rust.

If you happen to’re thinking about operating Harbinger, we’ve made it insanely straightforward to run a node so that you could be up and operating in beneath 5 minutes.
