State sync is a process that allows blockchain nodes to quickly synchronize with the current state of the blockchain without processing the entire history. Instead of downloading all historical blocks, a node requests the latest state from fully synced nodes, downloads and verifies this state, and then processes only the blocks from the snapshot point to the latest block. This method significantly reduces the time and resources needed to get a node up and running. It is especially useful for new node setups, disaster recovery, and scaling the network efficiently.

PLEASE READ IT CAREFULLY AND THOROUGHLY BEFORE EXECUTING !!! PLEASE READ IT CAREFULLY AND THOROUGHLY BEFORE EXECUTING !!! PLEASE, BACKUP YOUR PRIV_VALIDATOR_STATE.JSON ($HOME/.BINARYPATH/DATA/PRIV_VALIDATOR_STATE.JSON) TO AVOID TOMBSTONED WHILE SYNC TO LATEST HEIGHT BLOCK AFTER THAT RESTORE YOUR STATE.JSON TO ORIGINAL DIR PLEASE READ IT CAREFULLY AND THOROUGHLY BEFORE EXECUTING !!! PLEASE READ IT CAREFULLY AND THOROUGHLY BEFORE EXECUTING !!!

So how? Easy to use state sync isn't it? Wait it until ~20 minutes to catch latest height block
