Who is to blame in a distributed world?

Probably one of the most used images in Medium posts talking about CS :)
  • General nodes: Standard participants of the system. They deploy applications over the blockchain infrastructure, they conduct transactions, deploy smart contracts and perform any other task someone using a blockchain infrastructure would desire to perform.
  • Validator nodes: in charge of all the block validation process. They are responsible, among all, for the proposal and validation of the next block. In short, they are responsible for the validation of transactions through the operation of the consensus algorithm.
