Blockchain

I accidentally met with the founders of EMPERA blockchain. As you may know, despite the fact that I believe in the blockchain future, I am a bit skeptical about new projects and ideas in this field as there are many pure scams and unprofessional enthusiasts. However, after reading all the papers and after a deep talk with the founders I am now very excited about this particular project. And I want to share with you my insights (as well as a few skeptical unclarities to be 100% honest).

This is a continuation of my previous post Real Projects with Ethereum) - about how to setup a development infrastructure around real-life smart contract.

How to build a complex blockchain smart contract? What standard issues will you face with arrays, gas, different types of variables, deployment of contracts, etc? And how to solve them?

What is the right architecture for the app that should work with blockchain (and how it differs from traditional web architecture)? What libraries to use? How to configure environment?

Useful advanced info and techniques of writing and testing Smart Contracts: basic data types, reference data types, global variables, gotchas with dynamic arrays, validations and modifiers, debugging, generating random numbers, sending ether.

What is the right toolset for Blockchain development? Here are some keywords: nodejs, npm, web3, solc, ganache, mocha, metamask, rinkeby, infura, remix…

There is quite a high demand for blockchain development these days. We do some experience with it as a company (one complex multi-year project), but personally I only had high-level knowledge and I wanted to improve it…

So me and few of my colleagues have started the course “Ethereum and Solidity: The Complete Developer’s Guide” (https://www.udemy.com/course/ethereum-and-solidity-the-complete-developers-guide/)

I’ve just read recently published Big Ideas 2021 by ARK invest (these guys are investing billions of USD into disruptive tech companies) and want to share it. I really recommend to download and overview their slides for everybody who works in high-tech (yes, they are probably over-optimistic because of their role, but it’s really worth to look at): https://drive.google.com/file/d/1z3LpfrAQLRM07JDTi1ZnHEHPeszgIp7O/view?usp=sharing I am especially excited by what they call “Software 2.0” (deep learning).
