Lessons learned from 1400 Bitcoins loss

zk-SNARK (Zero-Knowledge Succinct Non-Interactive Argument of Knowledge) is the protocol of zero knowledge proof. ZCash cryptocurrency will be the one of first opened blockchain projects, which will utilize the implementation of this fascinating algorithm in the mechanics of blockchain. Zero knowledge proofs have huge potential and can be used or even revolutionize a lot of data exchange processes.

In this article I explain:

what is the zero knowledge proof;
what is, how works and what kind of math mechanics are hidden behind zk-SNARK.

Lisk is dedicated to develop custom blockchain based applications using Javascript. After Alpha SDK release it's possible for developers to prototype first custom applications. Technology is awaited by project investors since some time already. In that article I would like to go through the process of installing Lisk and all dependent technologies and then create and run own Lisk blockchain application.

How looks like the Lisk Alpha SDK application development process?
How looks like the code of custom blockchain?
What are the possibilities and potential of Lisk technology?

I would like to present software engineer point of view and describe both the positive and negative aspects.

Sharding is going to be scalability solution in upcoming Ethereum 2.0 and the enhancement hope for many other blockchains. Scalability is the speed key factor of the blockchain. This word is used to describe all the technology solutions which have the major goal: processing more transactions per second. Currently Bitcoin process about 3-7 transactions per second and Ehtereum about 7-15. With shards this result would be much increased.

What are the reasons of limited blockchain efficiency?
What's the main, basic idea of sharding?
What's the Blockchain Trillema?

I'm explaining in this article.

Lisk is one of the blockchain projects, whose primary focus is to enable building highly efficient blockchain based applications (dapps). The term "Lisk" at the moment can be called to describe the Lisk Core blockchain (with the native LSK cryptocurrency) and the SDK for building blockchain applications. The project is developed already few years, but the Alpha SDK version of Lisk is quite fresh.
Let's make short overview of the project genesis (history) and the current state.

The blockchain technology spreads. Mainly this can be visible in the context of cryptocurrencies popularity gain (which can be noticed by rising Bitcoin price). Blockchain became useful or even created plenty of new branches like tokenization which who knows - maybe will revolutionize the investments and the way we represent the ownership in general.

Choosing the right technology can impact development process and among the others: the performance of the solution. I would like to compare the performance of the Hyperledger Fabric chaincode implemented in the Node.js and Java.
