To ensure a sustainable future for blockchain and crypto, we need to reimagine the mining process and restructure PoW systems.
Blockchain mining networks are often victims of their success. The two contemporary realities that demarcate the mining landscape and cause blockchains to fall short of what they promise are 1) the ongoing technological arms race driven by inherent competitive greed; and 2) the rising energy costs associated with proof-of-work (PoW) mining. Blockchains built on the PoW consensus have become highly unequal and increasingly centralized in terms of their hash rate. This concentration of mining power in fewer and fewer hands is an attack on the fundamental requirement for distribution and decentralization that blockchains possess.In addition, the motivation to ramp up mining power has a knock-on effect in terms of runaway energy costs, which have the potential to cause irrevocable environmental harm, as
