Ask HN: Is there a carbon neutral blockchain?
Yesterday night when I was lying half awake in my bed I was thinking/dreaming of a carbon neutral blockchain.
Question: has anyone seen one or knows of someone who is trying to build one?
- guilhas 5y agoBlockchains that don't use proof of work are as wasteful as any other electronic platform Also proof of work can be translated into anything, like serving websites, images, processing video, and in that case is equivalent to any cloud or hosting provider
- gcthomas 5y agoNah. Longer version: Proof or work wastes energy by design, and while proof of stake is less wasteful, it is still not remotely as efficient or performant as modern banking systems. Proof of (hard drive) Capacity is wasteful of device production and running energy, and proof of elapsed time seems to be a lottery system, which looks likely to be difficult to secure in practice.

- hrhrhrhrhr 5y agoBlockchain itself cannot be carbon negative or neutral. Miners choose what energy source they use for mining, which can be anything from fossil fuels to geothermal energy from volcanoes.
