With our state sync services you will be able to catch up latest chain block in matter of minutes

ⓘ    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.

#Instructions

#Stop mantrachaind and reset database

sudo systemctl stop mantrachaind
cp $HOME/.mantrachaind/data/priv_validator_state.json $HOME/.mantrachaind/priv_validator_state.json.backup
mantrachaind tendermint unsafe-reset-all --home $HOME/.mantrachaind --keep-addr-book

#Download latest wasm

ⓘ    Currently state sync does not support copy of the `wasm` folder. Therefore, you will have to download it manually.
curl -L https://snapshots.lavenderfive.com/wasm/mantrachain/wasmonly.tar.lz4 | lz4 -dc - | tar -xf - -C $HOME/.mantrachaind

#Restart mantrachaind and check the log

sudo systemctl restart mantrachaind && sudo journalctl -u mantrachaind -f --no-hostname -o cat
