var TruncateBadger = false

TruncateBadger controls whether Badger is configured to truncate corrupted data. Especially on Windows, if the node is terminated abruptly, setting this may be necessary to recovering the state of the system.

However, Accumulate is not robust against this kind of interruption. If the node is terminated abruptly and restarted with this flag, some functions may break, such as synthetic transactions and anchoring.
