StakerHouseEpix state sync
State sync starts a Epix node from a recent block that our RPC serves, instead of replaying the chain's history.
Step 1: Stop the node, back up the validator state and reset
sudo service epix stop
cp $HOME/.epixd/data/priv_validator_state.json $HOME/.epixd/priv_validator_state.json.backup
epixd tendermint unsafe-reset-all --home $HOME/.epixd --keep-addr-bookStep 2: Configure state sync
The commands read a trusted height and hash from https://epix-rpc.stakerhouse.com, set the peer to sync from and restore the validator state.

LATEST_HEIGHT=$(curl -s $SYNC_RPC/block | jq -r .result.block.header.height)
BLOCK_HEIGHT=$((LATEST_HEIGHT - 2000))
TRUST_HASH=$(curl -s "$SYNC_RPC/block?height=$BLOCK_HEIGHT" | jq -r .result.block_id.hash)

sudo service epix start && sudo journalctl -fu epix -o cat
