@ -35,3 +35,16 @@ blocks and transactions to fewer nodes.
Reducing the maximum connected nodes to a minimum could be desirable if traffic
limits are tiny. Keep in mind that bitcoin's trustless model works best if you are
connected to a handful of nodes.
## 4. Turn off transaction relay (`-blocksonly`)
Forwarding transactions to peers increases the P2P traffic. To only sync blocks
with other peers, you can disable transaction relay.
Be reminded of the effects of this setting.
- Fee estimation will no longer work.
- Not relaying other's transactions could hurt your privacy if used while a
wallet is loaded or if you use the node to broadcast transactions.
- It makes block propagation slower because compact block relay can only be
used when transaction relay is enabled.
