Miners use powerful computers to solve complex puzzles and validate transactions, consuming large amounts of electricity.

[{"selector":"#anim-4bdb7ce7-80c9-46c3-b682-b96c98110fa1","keyframes":{"transform":["translate3d(-109.91254%, 0px, 0)","translate3d(0px, 0px, 0)"]},"delay":0,"duration":600,"easing":"cubic-bezier(0.4, 0.4, 0.0, 1)","fill":"both"}] [{"selector":"#anim-e61f776d-38d2-4cec-a3d0-3d1696a0e0d3","keyframes":{"opacity":[0,1]},"delay":0,"duration":600,"easing":"cubic-bezier(0.4, 0.4, 0.0, 1)","fill":"both"}] [{"selector":"#anim-0477d554-5202-41bf-ab5b-5c54f61602de","keyframes":{"transform":["scale(0.15)","scale(1)"]},"delay":0,"duration":600,"easing":"cubic-bezier(0.4, 0.4, 0.0, 1)","fill":"forwards"}]

In some cases, illegal operations have been found using huge amounts of electricity for Bitcoin mining.

[{"selector":"#anim-ebb85d23-b4cc-42b0-9bff-524ce640e5ca","keyframes":{"transform":["translate3d(108.52274%, 0px, 0)","translate3d(0px, 0px, 0)"]},"delay":0,"duration":600,"easing":"cubic-bezier(0.4, 0.4, 0.0, 1)","fill":"both"}] [{"selector":"#anim-4b0961f0-558c-4500-97b6-1c85caf6a1a0","keyframes":{"opacity":[0,1]},"delay":0,"duration":600,"easing":"cubic-bezier(0.4, 0.4, 0.0, 1)","fill":"both"}] [{"selector":"#anim-453f55b8-b377-44bc-b2a3-743cb65e5470","keyframes":{"transform":["scale(0.15)","scale(1)"]},"delay":0,"duration":600,"easing":"cubic-bezier(0.4, 0.4, 0.0, 1)","fill":"forwards"}]

Green cryptocurrencies offer an alternative, using a less energy-intensive method called "proof of stake."

[{"selector":"#anim-ba56bf22-7c52-4c22-8d73-ab238a6ef682","keyframes":{"transform":["translate3d(-104.8%, 0px, 0)","translate3d(0px, 0px, 0)"]},"delay":0,"duration":600,"easing":"cubic-bezier(0.4, 0.4, 0.0, 1)","fill":"both"}] [{"selector":"#anim-61fbbe2e-b6aa-4476-9e49-31ad6bb21c75","keyframes":{"opacity":[0,1]},"delay":0,"duration":600,"easing":"cubic-bezier(0.4, 0.4, 0.0, 1)","fill":"both"}] [{"selector":"#anim-cf05a1a2-2f01-4740-8a6c-158cf08a6887","keyframes":{"transform":["scale(0.15)","scale(1)"]},"delay":0,"duration":600,"easing":"cubic-bezier(0.4, 0.4, 0.0, 1)","fill":"forwards"}]

Ethereum's move to this method drastically reduced its energy usage, showing promise for other green currencies.

Sharding is another innovation aiming to make cryptocurrencies more eco-friendly by reducing energy needs.

[{"selector":"#anim-4f4af929-21bb-4fb0-a9fe-c08a1bd4f0a1","keyframes":{"transform":["translate3d(111.34328%, 0px, 0)","translate3d(0px, 0px, 0)"]},"delay":0,"duration":600,"easing":"cubic-bezier(0.4, 0.4, 0.0, 1)","fill":"both"}] [{"selector":"#anim-ff7cacd6-c844-4c0f-baa9-d084882ff240","keyframes":{"opacity":[0,1]},"delay":0,"duration":600,"easing":"cubic-bezier(0.4, 0.4, 0.0, 1)","fill":"both"}] [{"selector":"#anim-5b8a5b3a-27a5-4863-94ef-5e5998df408d","keyframes":{"transform":["scale(0.15)","scale(1)"]},"delay":0,"duration":600,"easing":"cubic-bezier(0.4, 0.4, 0.0, 1)","fill":"forwards"}]

Ethereum's upcoming upgrade incorporates sharding to improve transaction speeds and reduce costs.

[{"selector":"#anim-075ab8ce-aebd-4d0d-9a4e-f586afc61dde","keyframes":{"transform":["translate3d(-106.92521%, 0px, 0)","translate3d(0px, 0px, 0)"]},"delay":0,"duration":600,"easing":"cubic-bezier(0.4, 0.4, 0.0, 1)","fill":"both"}] [{"selector":"#anim-9f315291-55c6-4dc6-a176-0283ae0cde05","keyframes":{"opacity":[0,1]},"delay":0,"duration":600,"easing":"cubic-bezier(0.4, 0.4, 0.0, 1)","fill":"both"}] [{"selector":"#anim-c2e90092-be50-46c2-8e47-bdb6a963818e","keyframes":{"transform":["scale(0.15)","scale(1)"]},"delay":0,"duration":600,"easing":"cubic-bezier(0.4, 0.4, 0.0, 1)","fill":"forwards"}]

While green cryptocurrencies offer potential benefits for sustainability, they must address concerns about security, fairness, and accessibility as they evolve.
