Spending energy to secure and operate a payment system is hardly a waste. Like any other payment service, the use of Greenshilling entails processing costs.
Services necessary for the operation of currently widespread monetary systems, such as banks, credit cards, and armoured vehicles, also use a lot of energy.
Although unlike Greenshilling, their total energy consumption is not transparent and cannot be as easily measured.
Greenshilling mining has been designed to become more optimised over time Greenshilling carry environmental conservation at the forefront of the Greenshilling ethos.
Mining creates the equivalent of a competitive lottery that makes it very difficult for anyone to consecutively add new blocks of transactions into the block chain.
This protects the neutrality of the network by preventing any individual from gaining the power to block certain transactions.
This also prevents any individual from replacing parts of the block chain to roll back their own spends, which could be used to defraud other users.
Mining makes it exponentially more difficult to reverse a past transaction by requiring the rewriting of all blocks following this transaction.
There are various means to secure mining slots including environmentally friendly activity, buying and selling goods and services, participating in online gaming and much, much more.
