A Proof-Of-Work algorithm requires miners to do a certain amount of work that is compute-intensive to gain access to a service or the right to do something. This algorithm, by design, also requires that the work done shall not ...
"Blockchain technology is energy-intensive..." => No, it doesn't have to be.
Let's look at Proof-Of-Stake, an alternative to the energy-intensive Proof-Of-Work algorithm.

Proof-Of-Work is the name of a cryptographic algorithm that is used for some blockchains when new blocks are to be appended to the chain.

Let's take a higher-level look at how this one works, shall we?
\U0001f9f5\U0001f53d
Proof-Of-Stake is another algorithm, designed to create distributed consensus on a blockchain while being less energy-intensive and more scalable than Proof-Of-Work.
While having the same goal as Proof-Of-Work, distributed consensus, the process is completely different.
A Blockchain that uses Proof-Of-Stake chooses a node to create and append the next block randomly. This process of appending a new block to the chain is usually called "forging" and not "mining".
Whenever a node is chosen to forge a new block, the stake's age is reset to zero to distribute forging among all nodes ...
There are many other factors that can be taken into account and they are usually as individual as the blockchain using Proof-Of-Stake. Taking a look at the specific blockchain's whitepaper usually helps you to decide whether the chain is legit ...
When chosen, a forging node checks whether all transactions for the next block are valid. It then signs the block and appends it to the chain.
Well, we are at the end of this thread, and I hope you now understand Proof-Of-Stake, the alternative to the energy-intensive Proof-Of-Work a little better.

Excited to share our 2020 #Bitcoin review.
2020 will be remembered as the year the long fabled institutions finally arrived and #Bitcoin became a bonafide macroeconomic asset.
Below are the top highlights of each month for Bitcoin’s historic year.
1/
Bitcoin is now at all-time highs capping off an extremely successful year.
But it was by no means stable ride up.
2020 was a historically volatile year.
@YoungCryptoPM and I provided a detailed overview of every month of 2020 in all its
Jan.
3 days into the new year the US assassinated Iran’s top general Soleimani.
BTC surprisingly reacted to the events behaving like a safe haven as the risk of war increased.
The events provided the first hints of BTC potentially having graduated to a legitimate macro asset.
Feb.
COVID-19 reached a tipping point causing markets to crash.
BTC’s correlation with the S&P 500 reached an ATH in the following weeks.
This is when everyone learned BTC was not a recession hedge, it was a hedge against inflation and loss of confidence in fiat currencies. https://t.co/JB7dJ3qp6M
Mar.
Financial markets in free fall.
The liquidity crisis was so severe BTC experienced one of it’s worst days ever.
Now known as Black Thursday, on March 12, BTC plummeted as much as 50% to below $4,000 at its lowest point on the day.
BTC closed the day down 40%

Bitcoin is a hedge against inflation & loss of confidence in fiat, NOT a hedge against a typical recession.

I've just read one of the most lucid, wide-ranging, cross-disciplinary critiques of cryptocurrency and blockchain I've yet to encounter. 1/
It comes from David "DSHR" Rosenthal, a distinguished technologist whose past achievements including helping to develop X11 and the core technologies for Nvidia.
https://t.co/tkAMShno4k 2/
Rosenthal's critique is a transcript of a lecture he gave to Stanford's EE380 class, adapted from a December 2021 talk for an investor conference. 3/
It is a bang-up-to-date synthesis of many of the critical writings on the subject, glued together with Rosenthal's own deep technical expertise. He calls it "Can We Mitigate Cryptocurrencies' Externalities?"
The presence of "externalities" in Rosenthal's title is key. 4/
Rosenthal identifies blockchainism's core ideology as emerging from "the libertarian culture of Silicon Valley and the cypherpunks," and states that "libertarianism's attraction is based on ignoring externalities."
This is an important critique of libertarianism. 5/
