What Is The Average Blockchain Developer Salary in 2020?

Written By Ivan on Tech

May 11, 2020

A recent report from the San Francisco recruitment firm Hired suggests that the average blockchain developer salary is as high as between $150,000 and a whopping $175,000 a year. Moreover, the Californian recruitment firm notes this means blockchain developers get a substantial payday premium when comparing to software engineers.

In fact, reports find that blockchain developer salaries are more comparable to those specializing in artificial intelligence (AI). AI and blockchain are often put into the same category, seeing as they’re both relatively new technologies displaying massive potential.

Moreover, one reason for the recent blockchain developer salary rise is the exploding demand. Numerous high-profile companies are already looking into blockchain technology and are trying to attract blockchain developer talent. One way to stay competitive is by offering a high blockchain developer salary.

Blockchain developer salaries are surging

However, this surge in blockchain...

Decentralized Finance: What Is DeFi and Why Do We Need It?

Written By Ivan on Tech

May 11, 2020

Over the last year, the term “DeFi” has caused quite a stir in the decentralized community. Many in the community believe that DeFi, or decentralized finance, can completely turn the global economy on its head by making the finance sector transparent and more easily accessible.  The DeFi movement leverages decentralized networks to transform old financial products into trustless and transparent protocols that run without intermediaries:

  • The pitfalls of traditional finance.
  • What is DeFi, and why do we need it?
  • DeFi use-cases and applications.

DeFi has a unique opportunity to craft a unique niche for itself in the space. There are currently 1.7 billion people around the world who don’t have access to essential financial services. However, with a simple internet connection, they will be able to access smart contracts and experience immense financial growth and security with DeFi. So before we look into the nitty-gritty of this revolutionary system, let’s...

Byzantine Generals' Problem - An Introduction

Written By Ivan on Tech

May 06, 2020

The Byzantine Generals’ Problem is one of the most well-known and classic problems faced by decentralized networks. Solving this problem was one of the key developments in the creation of Bitcoin and, by extension, all other cryptocurrencies. In this article, we will see what the Byzantine Generals’ Problem is and how Bitcoin manages to solve this perplexing problem.

What is Byzantine Consensus?

The Byzantine generals’ problem was first theorized by the mathematicians Leslie Lamport, Marshall Pease, and Robert Shostak. The generals are a metaphor for nodes in a decentralized network. The core idea behind this thought experiment is this - How do you ensure that a peer-to-peer, distributed network with no central authority can make correct decisions, even if some of the nodes in it turn rogue? Can we make a distributed system that is “trustless” and doesn’t automatically assume that the participants are going to act ethically and work in the...

Blockchain: The Complete Guide - What Is The Blockchain?

Written By Ivan on Tech

May 05, 2020

The blockchain was initially introduced by Satoshi Nakamoto, the inventor of Bitcoin, as a time-chain concept. Bitcoin transactions would be created and validated in a decentralized, peer-to-peer network and stored in a public ledger, which was later called “the blockchain”. 

This distributed database where transactions get stored is what Satoshi referred to as time-chain or a chain of time-stamped blocks of transactions.

The most interesting features of blockchain technology are security and decentralization. Simply put, a blockchain allows users to send, receive, and store transactions in a time-stamped, public, open, and permissionless distributed database. These transactions are grouped together in blocks. Since blocks are hashed and linked together in chronological order, to alter the transactions in one block, an attacker would have to alter all subsequent blocks.

Therefore, blockchain technology seems to be an amazing and useful upgrade to distributed ledger...

When Is The 2020 Bitcoin Halving and What Is It?

Written By Ivan on Tech

May 05, 2020

Anyone keeping an eye on the cryptocurrency market will know that something big is about to happen. Specifically, Bitcoin is gearing up for its next Bitcoin halving event. This is something experts predict could set off a cryptocurrency rally - and will forever change the supply of Bitcoin.

What is the Bitcoin halving?

The Bitcoin halving, or more accurately the “Bitcoin block reward halving” cuts the mining reward for miners in half. As anyone familiar with Bitcoin and the blockchain will know, cryptocurrencies differ from fiat currencies. Particularly, there is no central authority that can “print” more Bitcoin.

Instead, miners “unlock” new Bitcoin through mining them, or by producing new blocks. There is a total Bitcoin supply of 21,000,000, which miners continually unlock. At the time of writing, a bit more than 18,360,000 Bitcoin are currently in circulation. However, Bitcoin halving events continually reduce the Bitcoin mining reward. ...

DeFi Industry Heats Up as A16z Announces $515 Million DeFi Fund

Written By Ivan on Tech

May 03, 2020

The venture capital firm Andreessen Horowitz, commonly known as “A16z”, is now announcing a new crypto fund. This crypto fund will focus on investments relating to cryptocurrency and blockchain technology startups. 

DeFi is one of the hottest industries in crypto

Furthermore, this fund will also invest in crypto startups that explore payments applications, Web 3.0, and - perhaps most notably - decentralized finance (DeFi). Decentralized finance, or the DeFi field, is getting a lot of attention lately.  

Additionally, the two co-leaders of the A16z fund, Chris Dixon and Katie Haun, agree that the DeFi space is one of the most interesting developments in the blockchain industry lately. 

In fact, they believe that DeFi and practical blockchain applications could transform how everything from lending and insurance to derivatives and trading is done. “We think the next wave of internet business models will come from crypto,” Dixon and Haun...

What Is DLT Trading? Detailed Breakdown of Distributed Ledger Technology Trading

Written By Ivan on Tech

May 01, 2020

The blockchain is often known as a “DLT” system. Specifically, DLT stands for distributed ledger technology, and is a digital decentralized system for verifying and recording asset transactions. This means that the system becomes more resilient, as it exists in various places at the same time.

DLT (Distributed Ledger Technology)

Anyone familiar with blockchain technology will likely recognize this definition of DLT. A previous Ivan on Tech Academy article, in which we answer “what is the blockchain”, demonstrates the advantages of distributed ledger technology in various industries. Moreover, this is primarily due to the unique and far-reaching application opportunities of DLTs.

Put simply, a distributed ledger consists of nodes that process and verify items. In doing so, DLTs generate records of various items and reach “consensus”, an agreement, on the items’ validity, or “veracity”. 

This means that a DLT ledger is...

What Is The Blockchain?

Written By Ivan on Tech

Apr 29, 2020

Blockchain is on the lips of everyone, from individuals to institutions these days. Analysts are calling the advent of blockchain (together with other cutting-edge technologies such as artificial intelligence, internet of things and virtual reality) the fourth industrial revolution. However, exactly what is blockchain? This article breaks it all down in a comprehensive “what is the blockchain 101” report.

 

Blockchain and cryptocurrencies 

Blockchain is perhaps most well-known as the technology that underpins Bitcoin and other cryptocurrencies. One should note that blockchain technology has wide-reaching applications that extend far beyond cryptocurrencies. However, the advent of Bitcoin and other cryptocurrencies did help blockchain technology gain more widespread exposure.

 

All of these different terms can be somewhat confusing, so we’re going to break it down. Cryptocurrencies are a type of medium of exchange, or means of payment. As such,...
