// In Clique PoA networks (Rinkeby, Görli, etc), consecutive blocks might have
|
|
// the same state root (no block subsidy, empty block). If a node crashes, the
|
|
// chain ends up losing the recent state and needs to regenerate it from blocks
|
|
// already in the database. The bug was that processing the block *prior* to an
|
|
// empty one **also completes** the empty one, ending up in a known-block error.
