Mining is the process of spending computing power to process transactions, secure the network, and keep everyone in the system synchronized together.
It can be perceived like the Greenshilling data centre except that it has been designed to be fully decentralized with miners operating in all countries and no individual having control over the network.
This process is referred to as “mining” as an analogy to gold mining because it is also a temporary mechanism used to issue new Greenshillings. Unlike gold mining, Greenshilling mining provides a reward in exchange for useful services required to operate a secure payment network. Mining will still be required after the last Greenshilling is issued.
Anybody can become a Greenshilling miner by giving service to the network and receiving reward for those services.
They receive newly created Greenshillings issued into existence according to a fixed formula.
For new transactions to be confirmed, they need to be included in a block along with a proof of work. Such proofs are very hard to generate because there is no way to create them other than by submitting a vast amount of calculations.
