What is the process for appending and agreeing on new blocks in a proof of stake system?

<p>In a proof of stake system, new blocks are appended and agreed upon through a process where anyone who holds coins inside of the system can participate, and the influence an agent has is proportional to the number of coins (or 'stake').</p> Signup and view all the answers
