In other words, they do not have to agree to change the protocol. Though there are a few gold diggers attempting to fill their pockets and certain projects that aren`t viable and shouldn`t be encouraged in any way. For users running a complete node, it is a fairly painless procedure to upgrade the software to the newest version. The process of locating a new block to extend the blockchain is known as mining. Proof-of-Work systems utilize cryptographic hashing algorithms to create the action of mining a block a complicated computation. Our software is totally incompatible with altcoins.

In Bitcoin, the most important reason is known as the network effect.
