As we’ve seen, ledger states can have simple or compound values, and to accommodate this, the world state database implementation can vary, allowing these values to be efficiently implemented. Options for the world state database currently include LevelDB and CouchDB. That concludes the major fields of the transaction – there are others, but these are the essential ones that you need to understand to have a solid understanding of the ledger data structure.

  • Once a consensus has been determined, all the other nodes update themselves with the latest, correct copy of the updated ledger.
  • Therefore, the app displays all data by default, and omits data only after subjecting the omission to extreme scrutiny.
