Interview with CTO Young Choe Part.2 - Current Blockchain Trilemma and KOK Platform


How do you think of the current blockchain technology? What are the problems that they faced?


Since the 2009, that is the year blockchain invented by Satoshi Nakamoto, Bitcoin, the second 

generation blockchain Ethereum, and third generation blockchain like EOS and AIDA. 

But, since then, blockchain has been suffering from three well-known problems.

Actually Vitalik Buterin defines these three problems, the conflicting problems so called trilemma.


What is the trilemma?


Trilemma simply can be described this way, A scalability cannot be improved without harming security and decentralization. 

If you want to improve scalability.Scalability is like an expanding blockchain users proportionally.

 If you want to increase so called scalability of the blockchain, then the security and decentralization have to suffer. That trilemma means we cannot achieve these three at once. 

There are many efforts to fix these problems by many other blockchains. Of course KOK Platform also works hard to solve these trilemma problems. 

I am pretty sure we solved these trilemma problems. I’ve evaluated many blockchains and also I was involved in blockchain designs in my past career path. 

So I combine all those experiences and studies to design KOK Platform. To simplify our design, we have three key concepts to solve those trilemma problems.


So KOK Platform can overcome those problems? How? 


Yes. We have three key factors like three pillars of KOK Platform

First one is DPOSS, Delegated Proof of Stake and Service.

Second one is Parallel PBFT.

Third one is, let me explain on the white board. 

The first, DPOSS

As I said, security and scalability is conflicting sometimes. 

By applying DPOSS, we can assign block producer (to) only DApp service node. We have DPOS plus S, Delegated Proof of Stake and Service. 

The service ability is applied in choosing BP. That’s the way we can avoid bribe attack and a scalability issues 

Also, to solve the security and the speed problems, we design PPBFT, Parallel Practical Byzantine Fault-Tolerance.


What is the third one to overcome those trilemma? (Would you) Please explain (over the whiteboard?). 


Yes. I need elaborate little bit more to describe the third one. That is very important.

To solve this trilemma problem, the third one is difficult to describe.

Actually KOK Platform has two layers inside.The bottom layer is MainNet. The above is KOK Platform. 

In a larger sense, we said this as a KOK Platform. In a narrower sense, the above part is KOK Platform, 

the lower part is KOK MainNet, blockchain MainNet. The upper part, KOK Platform, is more like a built-in DApps or intrinsic DApps.

To solve the decentralization problems, KOK Platform has its own wallet systems.

This wallet system helps all kinds of profit models such as leasing models and staking models.KOK Platform uses, of course, KOK Tokens.

Other DApps interact with KOK Platform and with the MainNet. This DApps use KOK Token. And also a major service node become BP of this platform.

At the beginning, we will have 21 BPs. And this 21 BPs will form 7 Regions, where 3 BPs in it.

So, that is the way we overcome decentralization problem.In KOK wallet system, we use Proof of Participation model. In other words, Leased Proof of Stake.

We use this concept to decentralize our network. Briefly speaking, our KOK ecosystem has a heterogeneous or hierarchical layers. 

In a DApps distribution and in a Wallet distribution This is the way, we overcome decentralization problem.
