Developer guide for POA

Hello, I want just to know some stuff about POA consensus?

  1. How voting look like?
  2. Also is voters all time need to be next to PC to validate transactions?
  3. If not, what algorithm is used to validate block and how to know if block is good or bad?
  4. Last question is there any tutorial how to make simple POA blockchain with basic concept?

You can find your answers in the POA Network Whitepaper:

The rest of the POA Network Github is an excellent resource as well.
