If you don’t know Uniswap, it’s a decentralized cryptocurrency exchange running on Ethereum that’s been very popular lately. And with anything popular in crypto, you have plenty of scams happening in broad daylight.

In this article, I’m going to look into a common type of honeypot scam on Uniswap that involves listing a “malicious” token that lets people buy it for ETH, but won’t let them swap it back and cash in.

Unlike centralized exchanges, Uniswap doesn’t employ an order book. …


Nietzsche said “God is dead”, but what has replaced the deceased deity? In 2020 it’s evident that the answer is, at least partially, capitalism. It seems now that it might be capitalism’s turn to go God’s way.

How did this happen?

Dunbar’s number, 150, is a suggested cognitive limit to the number of people with whom one can maintain stable social relationships. This means that a human can personally know and trust no more than 150 people. How then were we able to scale this network of trust to our modern, globalized society? …


We’ve been getting a lot of questions regarding Djitsu’s positioning in comparison to other notebooks and online IDEs. In response, we’ve decided to create this post and take this opportunity to explain why Djitsu is really cool.

Djitsu is an online IDE, a development environment for writing JavaScript straight in your browser. We employ the notebook paradigm: Code files are documents on the platform and contain code, text, comments, tests and anything you want to put there that’s supported, even spreadsheets. …


Notebook interfaces get a bad rap. It’s not that we dislike them, we just neglect them as tools for any serious software development. ML? Data visualization? Great! Building apps and websites using notebook interfaces? That’s a no-no.

The notebook coding interface is not a new idea. We can trace its origins from Donald Knuth’s idea of “Literate Programming”, an approach that advocates writing code, macros, documentation, and anything relevant, all in the same place.

“A simple literate program in noweb format.” from “Towards Literate Programming” by Matthew Smith, 2001

Knuth’s vision was to move away from writing code in the manner imposed by the computer and instead enable programmers to write programs in the order…


How does it feel to stare at a blank page of a new project, knowing the scope of what you need to build but having no idea of how you’re going to get there?

You might even be able to envision a vague approximation of what needs to be done, but the scope of it never fails to trigger your procrastination habit loop and send you scrolling Facebook or watching YouTube videos.

What to do?


If you’re reading this, you probably love web development. As a language, Javascript is both beautiful and powerful. React and other frameworks are a delight to work with once you know your way around them. But we can all agree that getting something to run on the web, in the way you want it to, is really damn hard. And it’s because of the tooling.

Now don’t get me wrong, the tools we have today are robust and powerful, but we can all admit that the amount of time you need to spend on configurations, boilerplate code, and setting up…


There are three types of folks you’d usually meet on Crypto Twitter.

  1. “The blockchain is just an overhyped technology. It’s slow and it sucks”
  2. “The blockchain is good for Bitcoin, and nothing else. Everything else is an alt/shitcoin/scam. Also, Satoshi is my lord and savior”
  3. “The blockchain is a monumental shift in computing, and we’re just in the beginning”

I’m in the third camp, and I’ll tell you why.

The market looks fine today, doesn’t it?

Have you heard the phrase “Be Your Own Bank”?

This phrase pretty much encapsulates the value proposition of Bitcoin: You don’t need banks because you have a decentralized network that enables…


Let me tell you a story.

In 2009 Satoshi debuted Bitcoin, the first public blockchain. Bitcoin gave us decentralized consensus and the ability to deploy trustless, anonymous systems on a large scale.

Later on, we had Ethereum which gave us even more functionality: Now we can deploy “smart contracts”, pieces of server-side code that execute on a trustless blockchain.

If Bitcoin was a blockchain with a single use, Ethereum is a programmable blockchain — it does what you tell it to.

TL;DR — Safebit is an operating system for the blockchain ecosystem. Our primary purpose is to build a strong interoperability layer between the various blockchains (Bitcoin, Ethereum, EOS) that will enable smooth cross-chain operation. One blockchain is great. Several weaved together start to form a more complex network — a new type of internet that we all like to call Web 3, also known as “the Financial Internet”.

Our intention is to build a strong backbone for developers to build the next generation of decentralized applications.
