Kill the middleman with a blockchain

Conference

Blockchain is a new buzzword that promises to revolutionize the way we manage data. If the data is stored in a blockchain there is no need for a middleman - the distributed database is stored on multiple and there is no need to have a centralized server that will ensure that the transactions can be trusted.

The best way to understand how a blockchain works is to build one. During this presentation, we'll start with covering the basics (hash, nounce, block, smart contracts) and then we'll create a simple blockchain and a web client for it.

Disclaimer. This presentation is not about bitcoins, and it won't make you rich overnight.

Modern JavaScript

Conference

In this presentation, you’ll learn how to write code using the latest syntax of JavaScript. While most of the current web apps use the ECMAScript5 version of the language, all the modern web browsers fully support the ES6 specification. Some of them started supporting the ES7 and ES8 syntax.

You’ll learn how to use JavaScript classes, fat arrow functions, destructuring, spread operators, and write asynchronous code with promises and async-await keywords.
