When it comes to blockchain technologies, consensus achievement is a crucial topic of interest. One of consensus algorithms is called Proof-of-Capacity.
The simplest blockchain projects are heavily dependent on member interaction. By the word ‘simplest’ we mean the most basic proposals like Bitcoin, Ethereum, and similar. They all use blockchain and some simple algorithms to operate. In contradiction, in such projects as IoTa transactions are not united in a block structure. Other complex examples are Ripple or Stellar that interact with the real banking system, thus performing complex synchronization functions.
