Bitcoin and its competitors will emerge greener, more democratic, and stronger

Last week, the Peoples’ Bank of China made an unprecedented move, declaring all cryptocurrency transactions in the country illegal. Crypto exchanges are reportedly scrambling to drop Chinese users before the ban comes into effect, and cryptocurrencies like Bitcoin and Ether dropped as much as 7% when the ban was announced…

How to make the next generation of bankers better than today’s

I took a bit of heat last week for suggesting that the blockchain movement may have gone largely off course. Some asked: What about NFTs? Or the decentralized autonomous corporations? Aren’t Bitcoin and Ethereum doing all sorts of great things?

Blockchain takes a substantial toll on the environment that experts are beginning to reckon with

The price of one bitcoin, as I write this, is $57,383 — more than 10 times what it cost just a year ago. That price is volatile, so it will be different by the time you read this. But rest assured it will remain expensive.

There’s another toll, though, for…

The first two eras of the internet

During the first era of the internet — from the 1980s through the early 2000s — internet services were built on open protocols that were controlled by the internet community.

Californians alone use more power playing games and heating their pools than entire countries in Africa. That has to change.

Modern life is amazingly energy intensive. All those computers, data servers, and air conditioners devour a lot of electricity. In fact, virtually everything about how we live, move around, communicate, and work is embedded with immense quantities of energy.

Blockchain technology explained in simple words

Blockchain technology is probably the best invention since the internet itself. It allows value exchange without the need for trust or a central authority. Imagine you and I bet $50 on tomorrow’s weather in San Francisco. I bet it will be sunny, you that it will rain. …

Loopholes in lending laws are allowing cryptocurrency users to escape taxes — and the government can’t keep up

Wealthy families and merchants first conjured up the idea of offshore banking in 19th century Europe, seeking a place to store funds away from tax-hungry governments in the aftermath of the Napoleonic wars. Since then, it’s been a race to the bottom. …
