Blockchain not to blame

Blockchain not to blameHitcoins

"Bitcoin is ‘disgusting and contrary to the interests of civilization’ says famed investor Charlie Munger"   https://www.theregister.com/2021/05/03/berkshire_hathaway_annual_meeting_tech_highlights/

I don’t think that this report is the denial of blockchain and the like, although I, as a man who studied economics as a university student, have to agree to their observation I hate the Bitcoin success and I don’t welcome a currency that’s so useful [for] kidnappers in our stores and so forth,” “Nor do I like just shuffling out a few extra billions and billions and billions of dollars to somebody who just invented a new financial product out of thin air.” 

I had recently referred to the block chain and cryptocurrencies as per “Blockchain and Carbon Footprints”  in which I wrote the following.

“Could a ‘Crypto Climate Accord’ erase cryptocurrencies’ carbon footprint?” https://www.theverge.com/2021/4/8/22373524/cryptocurrency-climate-accord-bitcoin-carbon-footprint

Is the carbon footprint of blockchain an enemy of the habitable climate?

We should distinguish the blockchain used for cryptocurrency gambles (1) and used for meaningful applications (2).

(1) We are of the view that the current cryptocurrencies are no more than a digital version of Tulipomania. I am not willing to support the idea of consuming a huge amount of electricity for entertaining gamblers.

(2) We need to support the concept of blockchain to be used for the benefits of society, expecting that some people will find a new way of running it in a more eco-friendly way in due course.

Our business is providing a valid identity assurance to the people who resort to the likes of blockchain technologies to safely manage their information assets in a way compatible with the value of democratic society.
