May I suggest...

gridcoinresearchd getmininginfo | jq -r '"
# TYPE gridcoin_network_difficulty
gridcoin_network_difficulty \(.difficulty.current)
# TYPE gridcoin_tts_days gauge
gridcoin_tts_days \(."time-to-stake_days")
# TYPE gridcoin_reward_pending gauge
gridcoin_reward_pending \(.BoincRewardPending)
# TYPE gridcoin_network_block
gridcoin_network_block \(.blocks)
"'

echo '# TYPE gridcoin_peers_count gauge'
gridcoinresearchd getpeerinfo | jq -r 'group_by(.subver)
  | map("gridcoin_peers_count{version=\"\(.[0].subver | capture("(?<v>[0-9.]+)").v)\"} \(length)")
  | join("\n")'

gridcoinresearchd getlaststake | jq -r '"
# TYPE gridcoin_laststake_seconds gauge
gridcoin_laststake_seconds \(.elapsed_seconds)
# TYPE gridcoin_laststake_mint gauge
gridcoin_laststake_mint \(.mint)
"'
