The whole idea behind blockchain technology is that it’s decentralized. This concept means no single entity can affect the cryptocurrencies.

Harvesting is an alternative to the traditional mining used to maintain the integrity of a blockchain network. It was designed by a blockchain platform called NEM to generate its own currency called XEM. According to finder.com, this is how harvesting works: “Every time someone carries out a transaction, the first computer to see and verify the transaction will notify nearby users of that transaction, creating a cascade of information. This process is called ‘generating a block.’ Whenever someone with more than 10,000 vested XEM generates a block in NEM, they receive the transaction fees on that block as payment.” Also, as explained earlier in this chapter, harvesting uses a PoI system rather than PoS and PoW.

Cryptocurrencies are typically open source. That means that miners, nodes, and harvesters alike can join and use the network without paying a fee.
