Proof-of-Work Alternatives: Massive electric consumption by cryptocurrency mining

Posted by in categories: bitcoin, cryptocurrencies, economics, energy, environmental

Some blogs and news outlets eschew long titles. Publishers want readers to scan a list of topics that fit on one-line each. But, a better title for this article would be:

“Massive electric consumption by cryptocurrency mining:
An unfortunate environmental nightmare will soon pass!
… Proof-of-Work alternatives are on the horizon”

A considerable amount of electricity is used in the process of mining Bitcoin and other cryptocurrencies. Miners are effectively distributed bookkeepers, and this use of resources is part of a system called “proof-of-work”. It keeps the books fair, honest, and without an ability for the miners to collude (In other words, they cannot ‘cook the books’).

How does the Blockchain ‘know’ you have printed a paper wallet?

Posted by in categories: bitcoin, cryptocurrencies, economics, internet

Let’s say that you no longer trust your currency exchange to host your Bitcoin wallet and you don’t trust a Trezor or Nano hardware wallet. You don’t trust your memory and you don’t trust your kids. And you certainly know better than to keep your wealth in your PC or phone. That would be downright crazy—right? What can you do?!

A growing number of people are printing paper wallets. It is the ultimate form of security. Some individuals even delete their cloud wallet, leaving everything to a string of hex characters or a QR code printed onto a slip of paper. (NB. You had better be certain that you and a few trusted individuals know how to find that piece of paper!)

But here’s an interesting mystery. If you print the paper wallet off-line and delete your other wallets, then how can the blockchain ‘know’ that you have changed wallets? The short answer: It doesn’t and you haven’t!

Let’s explore a bit deeper…

Should we ‘out’ Bitcoin creator, Satoshi?

Posted by in categories: bitcoin, cryptocurrencies, economics

Everyone likes a good mystery. After all, who isn’t fascinated with Sherlock Holmes or the Hardy Boys? The thirst to explore a mystery led us to the New World, to the ocean depths and into space.

One of the great mysteries of the past decade is the identity of Satoshi Nakamoto, the inventor of Bitcoin and the blockchain. Some have even stepped forward in an effort to usurp his identity for fame, infamy or fortune. But in this case, we have a mystery in which the subject does not wish to be fingered. He prefers anonymity.

This raises an interesting question. What could be achieved by discovering or revealing the identity of the illusive Satoshi Nakamoto?…

The blockchain and Bitcoin present radically transformative methodologies with far ranging, beneficial impact on business, transparency and social order.

Blockchain can dramatically reduce pollution and traffic jams

Posted by in categories: bitcoin, cryptocurrencies, Elon Musk, energy, environmental, futurism, sustainability, transportation

The World Economic Forum has posted an article that hints at something that I have also suggested. (I am not taking credit. Others have suggested the idea too…But advancing tech and credible, continued visibility may help us to finally be taken seriously!)

I am not referring to purchasing and retiring carbon credits. I like that idea too. But here is a blockchain idea that can enable fleets of autonomous, shared, electric vehicles. Benefits to individuals and to society are numerous.

The future is just around the corner. Non-coin applications of the blockchain will support many great things. Goodbye car ownership. Hello clean air! The future of personal transportation.

Perspective of a former “Bitcoin Maximalist”

Posted by in categories: bitcoin, cryptocurrencies

This pundit is very cogent, as he criticizes early Bitcoin adopters and evangelists. He believes that they are too wrapped up in the original blockchain implementation, and that what goes up must come down—or, at least, that the earliest implementation of a new technology cannot adapt and become the durable leader in the field that it launched.

It’s the 15-minutes-of fame argument. But, I disagree! There are plenty of reasons to support, repair and expand Bitcoin—rather than fragment goodwill and abandon and a viable, two-sided network into 3,000 altcoins and blockchain startups.

Still, the author is very very bright and defends his position.
