|---------------------------------|--------------------------------------------------------------------------------------------------------------------------------------
| `--max-concurrency` | Max number of threads to use for a parallel jobs. The default value `0` uses the number of CPU threads.
| `--prep-blocks-threads` | Max number of threads to use when computing block hashes (PoW) in groups. Defaults to 4. Decrease this if you don't want `monerod` hog your computer when syncing.
+| `--fast-block-sync` | Sync up most of the way by using embedded, "known" block hashes. Pass `1` to turn on and `0` to turn off. This is on (`1`) by default. Normally, for every block the full node must calculate the block hash to verify miner's proof of work. Because the CryptoNight PoW used in Monero is very expensive (even for verification), `monerod` offers skipping these calculations for old blocks. In other words, it's a mechanism to trust `monerod` binary regarding old blocks' PoW validity, to sync up faster.
+| `--block-sync-size` | How many blocks are processed in a single batch during chaing synchronization. By default this is 20 blocks for newer history and 100 blocks for older history ("pre v4"). Default behavior is represented by value `0`. Intuitively, the more resources you have, the bigger batch size you may want to try out. Example:
`./monerod --block-sync-size=500`
| `--bootstrap-daemon-address` | The host:port of a "bootstrap" remote open node that the connected wallets can use while this node is still not fully synced. Example:
`./monerod --bootstrap-daemon-address=opennode.xmr-tw.org:18089`. The node will forward selected RPC calls to the bootstrap node. The wallet will handle this automatically and transparently. Obviously, such bootstraping phase has privacy implications similar to directly using a remote node.
| `--bootstrap-daemon-login` | Specify username:password for the bootstrap daemon login (if required). This considers the RPC interface used by the wallet. Normally, open nodes do not require any credentials.
