The energy consumption problem only applies to certain blockchains, like bitcoin, based on software that uses a Proof Of Work algorithm: it requires tons of constant computer processing power, hence tons of electricity, to prove that the computer running the software adds something valuable to the network. Real life comparison: a bricklayer needs to works his socks off all day to get rewarded with a paycheck.ShaunWhite wrote: ↑Mon Jan 29, 2018 12:44 pmIn a world like the one described on the 'Water' thread, whoever thought blockchain was a good idea needs their head testing. It's barely got going and already using over 30Twh of energy.

Newer blockchains are based on software that use a Proof Of Stake algorithm, which consumes low/normal amounts of energy. Basically the only thing the computer needs to prove to the network is that its owner believes in the project. It does so by keeping x tokens in a designated wallet. Real life comparison: an investor needs to hold x shares of a company to get rewarded with dividends.
