State Sync allows a new node to join the network by fetching a snapshot of the application state at a recent height instead of fetching and replaying all historical blocks. Since the application state is generally much smaller than the blocks, and restoring it is much faster than replaying blocks, this can reduce the time to sync with the network from days to minutes.

Currently state sync does not support copy of the wasm
folder. Therefore, you will have to download it manually.
Copy curl -L https://snapshots.takeshi.team/osmosis/wasm_latest.tar.lz4 | lz4 -dc - | tar -xf - -C $HOME/.osmosisd
Restart the service and check the log
Copy sudo systemctl start osmosisd && sudo journalctl -u osmosisd -f --no-hostname -o cat
