Nonforking-blockchains

Invariant that blockchains do not fork: proof that it holds in every reachable state.

This completes nonforking-blockchains-def-and-init and nonforking-blockchains-next by showing that the invariant holds in every reachable state.

Subtopics

Nonforking-blockchain-p-always

The invariant holds in every state reachable from an initial state via a sequence of events.
