In a blockchain, decentralisation refers to transferring control and decision-making from a centralised entity (individual, organisation, or group) to a distributed network.
A blockchain powers cryptocurrencies, and in contrast to traditional currencies, they do not have a central authority issuing or regulating them. The decentralisation concept, along with other blockchain native characteristics, paves the cryptocurrencies future.
However, different Blockchains’ energy consumption has become an increasingly important topic for all crypto communities. The reason for this is a relatively straightforward — massive carbon footprint. Most crypto adopters are young people with a solid intent to save our planet. Therefore, to win them, blockchain must become green.
