cvp is a pvtop-like utility, plus miracles

A simple utility for watching pre-vote status on Tendermint/CometBFT chains. It will print out the current pre-vote status for each validator in the validator set. Useful for watching pre-votes during an upgrade or other network event causing a slowdown.

This is a full rework of pvtop by @blockpane and plus some miracles

  • Live-streaming mode (view sample), sharing pre-voting information to everyone: cvp --streaming
  • Display Block Hash fingerprint which the validator voted on
  • Allow scrolling on terminal UI (thanks to @freak12techno)

Basic usage

cvp
# => use http://localhost:26657

# For streaming mode
cvp https://example.com:26657 --streaming
# or resume streaming in case of mistakenly exit
cvp https://example.com:26657 --resume-streaming
cvp 19000
# => use http://localhost:19000
cvp https://rpc.cosmos.network
# => use https://rpc.cosmos.network
cvp https://rpc.example-consumer.network https://rpc.cosmos.network
# => use https://rpc.example-consumer.network as consumer network RPC endpoint
# and use https://rpc.cosmos.network as producer network RPC endpoint (typically Cosmos Hub)

Notes:

  • Default fetching consensus state is 3 seconds, can reduce to 1s by adding -r flag.
  • In case interrupted from streaming mode, should resume instead of start a new session. Resume by adding --resume-streaming flag and provide the latest session id and key printed in previous run.
  • Streaming session has default expiration time is 12 hours.
