In little over a decade, Bitcoin and other cryptocurrencies have become mainstream. News headlines have focused on the spectacular price growth of these assets, yet the more compelling story is the wave of interest from the corporate sector, which is one of the underlying factors influencing the price.

A quick look at Bitcoin Treasuries reveals that more than $50 billion worth of Bitcoin is held on the balance sheets of companies. …

In the first part of this two-part series, we looked at one of the most commonly asked questions about blockchain networks: how they can scale up to accommodate millions of transactions.

If we turn to Ethereum, we see a network that is under pressure from many different requirements, and which has been plagued with periods of congestion and high fees. Because the majority of DeFi protocols and NFT marketplaces run on Ethereum, it has in many ways become a victim of its own success.

Many people who would have otherwise wished to get started in DeFi have been deterred by…

Talk to someone for any length of time about Bitcoin, and the question of scaling arises. From a technical point of view, scalability is not a challenge that is unique to cryptocurrencies, or to blockchain-based applications. Any application or network that is designed for high traffic or multiple concurrent users needs to be programmed and configured in such a way that many people can access it simultaneously without degradation of performance.

Public proof-of-work blockchains pose specific challenges because energy-intensive transactions must be recorded and consensus agreed on thousands of different computers to ensure the integrity of the network’s history. …

First things first — the Original paper can be found here:

In Dawn of the New Everything, his seminal work on virtual reality, Jaron Lanier describes Virtual Reality as “the substitution of the interface between a person and the physical environment with an interface to a simulated environment”. In truth, this is only one of dozens of different VR definitions in this important book, but it is crucial because it raises so many questions.

How do we, as humans in the physical realm, interface with worlds that have been conjured from the imagination, where the laws of physics do…

This week, Deutsche Bank raised some eyebrows (and upset quite a lot of people) by suggesting that employees who chose to work from home should pay an extra five per cent tax. In Britain, where working from home currently means you are liable for tax relief, this may sound counterintuitive. So, what was the idea?

During this year’s global pandemic, the plight of businesses that depend on the workers who normally pack out large office blocks…

Ownership, identity and economics in the Metaverse

COVID-19 has changed the way we work, study and socialize, at least temporarily. Many of those who were privileged enough to transfer to remote working instead of losing their jobs will never return to the office, even if they want to. Companies have found — often to their surprise — that they can make significant cost and efficiency savings on office facilities, with little impact on output. And it wasn’t only the workplace that became digital…

Dishoom pounds — stablecoins in physical form, exchangeable for awesome food!

Nothing is simple any more. As far as your average shopper was concerned in the 20th and early 21st century, ‘money’ was the pound or peso in your pocket or the dollar or Deutschmark in your drawstring purse.

‘Money’ was printed paper or sometimes stamped metal rounds issued by your country’s central bank which sometimes bore an inscription promising to pay the bearer the requisite amount.

Mythology and national pride often surrounded these national currencies — and still does, to some…

I doubt this post will age well. In less than 48 hours, we’ll know a lot more about Libra, Facebook’s intriguing digital currency offering — and maybe the answers to these questions will become clear.

As an enthusiastic proponent of Bitcoin and a Facebook refusenik (I created an account once, some years ago under a burner email address in order to test an app but have never actually used it), I’m unlikely to be an early adopter — or any kind of adopter — of Libra.

But whether you’re horrified at the idea, love it or are indifferent, this feels…

The past is a foreign country: they do things differently there. Technology years are like dog years — and this is even more the case with blockchain tech, where one year can sometimes feel more like 10.

While anyone who works in blockchain development is used to the idea of pivoting their business strategies and iterating over their code base to take advantage of changes so rapid they make JavaScript frameworks look slow to evolve, it…

Regardless of the millions of words that have been written about cryptocurrencies and blockchain technology, it seems there is still a whole lot of confusion and urban folklore around the subject.

I’ve handpicked ten top crypto fallacies that I’ve heard people say, write or ask over the last few years and explained why they are wrong, wrong, wrong.

  1. You have to own a whole Bitcoin!

You can even get a T-shirt stating the contrary, but it’s curious how this misconception has hung around. …
