The latter has actually been removed per October 1, 2019. Did you know Bitcoin works on an energy-intensive network? Ever because its creation Bitcoin's trust-minimizing consensus has been allowed by its proof-of-work algorithm. The devices carrying out the "work" are consuming huge quantities of energy while doing so. Additionally, the energy used is mainly sourced from fossil fuels.

A separate index was created for Ethereum, which can be found here. What kind of work are miners carrying out? New sets of deals (blocks) are added to Bitcoin's blockchain roughly every 10 minutes by so-called miners. While working on Go here aren't needed to rely on each other.
