Exactly 14 years ago , Satoshi Nakamoto designed the most pathetic / inefficient system ever invented by humankind : the blockchain.
Today, it weights 60 000 tons, wastes constantly 10 gigawatts .. to process less than 7 transactions per second :
Less than a 33 bps modem from 1990.
This could be joke if it didn't have such gigantic environmental impact, wasn't enabling billion dolllars ransomware industry and was not crushing thousands of lives in the process.
Totally inaccurate!
The blockchain is not responsible for any of that; of itself, the blockchain is just another computer algorithm. What you are firing off about is cryptocurrency. I agree that is an evil that should be stopped immediately. However, the blockchain can be, and is, used for a variety of other purposes it is a mere coincidence that it is used as the security system in cryptocurrencies.
The thing that wastes that enormous amount of energy is the mathematical problem that the inventors of cryptocurrency require to be solved to generate a Bitcoin or whatever else the inventors of such currencies choose to call their tokens. That has nothing whatsoever to do with the technology of blockchains!
@Paulos_the_fog "the blockchain can be, and is, used for a variety of other purposes"
I failed to find a valid / production use case that was not better implemented with centralized DB + asymmetric signatures.
