State Sync

Instruction

Set variables

PROJECT_NAME=archway
PROJECT_TYPE=mainnet
PROJECT_SERVICE=archwayd
PROJECT_BINARY=archwayd
PROJECT_FOLDER=~/.archway
SNAP_RPC="https://rpc-archway.mms.team:443"
PEERS="[e-mail]:56108"

Add peer

sed -i.bak -e "s/^persistent_peers *=.*/persistent_peers = \"$PEERS\"/" ${PROJECT_FOLDER}/config/config.toml

Stop and reset node

sudo systemctl stop ${PROJECT_SERVICE}
cp ${PROJECT_FOLDER}/data/priv_validator_state.json ${PROJECT_FOLDER}/priv_validator_state.json.backup
${PROJECT_BINARY} tendermint unsafe-reset-all --home ${PROJECT_FOLDER} --keep-addr-book

Configure State Sync

LATEST_HEIGHT=$(curl -s $SNAP_RPC/block | jq -r .result.block.header.height);\
BLOCK_HEIGHT=$((LATEST_HEIGHT - 2000)); \
TRUST_HASH=$(curl -s "$SNAP_RPC/block?height=$BLOCK_HEIGHT" | jq -r .result.block_id.hash)
sed -i.bak -E "s|^(enable[[:space:]]+=[[:space:]]+).*$|\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\"|" ${PROJECT_FOLDER}/config/config.toml

Restore priv_validator_state.json

mv ${PROJECT_FOLDER}/priv_validator_state.json.backup ${PROJECT_FOLDER}/data/priv_validator_state.json

Restart Node

sudo systemctl restart ${PROJECT_SERVICE}
journalctl -fu ${PROJECT_SERVICE} -o cat
