No-history is a method for synchronizing a wallet by scanning the UTXO
set. It can be useful for checking whether seed phrase backups have
money on them before committing the time and effort required to
rescanning the blockchain. No-history sync is compatible with pruning.
The sync method cannot tell which empty addresses have been used, so
cannot guarentee avoidance of address reuse. For this reason no-history
sync disables wallet address generation and can only be used with
wallet-tool and for sending transactions without change addresses.
