STATE SYNC SERVICE
 

Please make sure You have latest, officially launched version of Umee binaries.



sudo systemctl stop umeed.service
umeed tendermint unsafe-reset-all --home $HOME/.umee

SNAP_RPC="http://173.212.215.104:26657"; \
LATEST_HEIGHT=$(curl -s $SNAP_RPC/block | jq -r .result.block.header.height); \
BLOCK_HEIGHT=$(($LATEST_HEIGHT - 1000)); \
TRUST_HASH=$(curl -s "$SNAP_RPC/block?height=$BLOCK_HEIGHT" | jq -r .result.block_id.hash); \
echo $LATEST_HEIGHT $BLOCK_HEIGHT $TRUST_HASH

sed -i.bak -E "s|^(enable[[:space:]]+=[[:space:]]+).*$|\1true| ; \
s|^(rpc_servers[[:space:]]+=[[:space:]]+).*$|\1\"$SNAP_RPC,$SNAP_RPC\"| ; \
s|^(trust_height[[:space:]]+=[[:space:]]+).*$|\1$BLOCK_HEIGHT| ; \
s|^(trust_hash[[:space:]]+=[[:space:]]+).*$|\1\"$TRUST_HASH\"|" $HOME/.umee/config/config.toml; \
wget -qO $HOME/.umee/config/addrbook.json https://snapshots.theamsolutions.info/umee-test-adrb.json

sudo systemctl restart umeed.service && sudo journalctl -u umeed.service -f -o cat

Use command below to switch off your State Sync mode, after node fully synced to avoid problems in future node restarts!

sed -i.bak -E "s|^(enable[[:space:]]+=[[:space:]]+).*$|\1false|" $HOME/.umee/config/config.toml

A fully synced node supposed to be ready in 10-15 min. depending on computer/bandwidth power.
Enjoy.
