“Blockchains don’t scale.” You’ve probably heard this a million times. A couple years ago, it felt like a real threat to the industry. How can we bank the unbanked if we can’t even process 15 transactions per second?But big problems fuel innovation. And blockchain scalability was a big problem. It quickly caught the attention of engineers and scientists, and, fast forward to today, we’re getting more and more confident that blockchains can scale.

Here’s something most new Web 3.0 developers have trouble understanding: when you ship code, it can’t be patched and updated later. This is a big departure from the iterative development method that we all know and love — where we break development into smaller parts and build it up over many iterations. By adding features one-by-one, we can improve app functionality over time — all while growing a user base. In Web 3.0, this just can’t be done. Blockchain changes everything — including the possibility for iterative development.

The architecture of Web 3.0 applications are completely different from Web 2.0 applications. But all of that’s changing.Blockchain technology has unlocked an exciting new direction for Web 3.0 applications. In this article, we're going to focus on what the Ethereum blockchain brings to the table.

​In the blockchain world, you must have heard about “Web 2.0” and “Web 3.0” frequently.But what do Web 2.0 and Web 3.0 mean? Which one is better? For us to make any sense of what we mean by “Web 3.0”, we need to rewind to Web 1.0 and start there.

Remember when the “Internet of Things” (IoT) was all the rage? The concept was simple: we would put sensors on every physical object imaginable, turning objects from “dumb” to “smart.” But here we are in 2021, still waiting for the IoT revolution to happen. Could Helium be the blockchain that makes this pipe dream a reality?

Binance became the world’s large crypto exchange almost overnight. Here is the backstory for how it all happened.

I’m launching an email course for crypto newcomers who want a guided introduction to cryptocurrency. This course is not designed for “nerds” or those “in the know”, but for normal people seeking to satisfy their curiosity and understand what all the fuss is about.‍

COVID-19, for better or worse, is the perfect catalyst to accelerate crypto adoption.‍

The crypto industry never really rests. It all started with the launch of Bitcoin in 2009. When it first came out, everyone thought Bitcoin was the holy grail of digital currencies. What was once believed to be impossible was now real: The first ever peer-to-peer (P2P) payments network.

In part 1, we’ve talked about Cosmos from the viewpoint of building a single blockchain and blockchain application. But as we noted earlier, one of Cosmos’ biggest value propositions is interoperability — the ability to communicate across MANY blockchains.

Distributed systems can be difficult to understand, mainly because the knowledge surrounding them is distributed. But don’t worry, I’m well aware of the irony. While teaching myself distributed computing, I fell flat on my face many times. Now, after many trials and tribulations...

Many of us are guilty of describing blockchains as “trustless” systems. However, I’ve come to realize that the term “trustless” is ambiguous, confusing, and most importantly, inaccurate. Blockchains don’t actually eliminate trust. What they do is minimize the amount of trust required from any single actor in the system.

There’s no question that blockchain technology has enormous potential.Decentralized exchanges, prediction markets, and asset management platforms are just a few of the exciting applications being explored by blockchain developers. Exciting enough, in fact, to raise over billions in ICOs...

Odds are you’ve heard about the Ethereum blockchain, whether or not you know what it is. It’s been in the news a lot lately, including the cover of some major magazines, but reading those articles can be like gibberish if you don’t have a foundation for what exactly Ethereum is. So what is it?

When the first home telephones were being installed in the 1870s, the companies selling them had a problem: phones aren’t very useful if you can only call a few people. However, this challenge got easier and easier as the networks expanded, since every new customer’s presence in the phone book...

Blockchains, as it stands today, are limited in their ability to scale.That’s not to say that this will be the case forever, but it’s definitely true today. In fact, I’d argue it’s one of the biggest technological barriers we face with blockchain technology today.

The Crypto market is gaining lots of steam. Gravity-defying price rallies and multi-million dollar token sales are commonplace, as are front-page headlines discussing Ethereum, Bitcoin, ICOs, tokens, hard forks, and other technical topics.
