Blockchain and Carbon Footprints
“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.
