SNAP_RPC=\"https://orai-rpc.imdev.app:443\"
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)
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/.oraid/config/config.toml
