This paper discusses the intersection of environmentalism and cryptoanarchism, in the form of Gridcoin, a cryptocurrency which aims to mitigate the environmental impact of cryptocurrency mining, through the implementation of two methods: a Proof-of-Research scheme and a Proof-of-Stake protocol. This raises questions about the need for an environment-friendly consideration of the costs of cryptocurrency mining.
