Bonsai based reference test worldstate (hyperledger#5686)
Browse files Browse the repository at this point in the history
* create a bonsai based reference test worldstate
  -> getOrCreate in BonsaiWorldStateUpdateAccumulator - do not throw if we discover an empty account in a non-null BonsaiValue<Account>
  -> add curentStateRoot to t8n
  -> storageEntriesFrom and streamAccounts implemented in BonsaiWorldStateKeyValueStorage
  -> add endKey version of streamFromKey
* bonsai fix for self-destruct and create2 at the same address and same block
