  • The validator is then responsible for checking that new blocks propagated over the network are valid and occasionally creating and propagating new blocks themselves
  • If they try to defraud the network (for example by proposing multiple blocks when they ought to send one or sending conflicting attestations), some or all of their staked ETH can be destroyed.
  • When the network performs optimally and honestly, there is only ever one new block at the head of the chain, and all validators attest to it. However, it is possible for validators to have different views of the head of the chain due to network latency or because a block proposer has equivocated. Therefore, consensus clients require an algorithm to...
