Monitor pool tickers for unreasonable updates #84

Closed tdiesler closed 2 years ago

tdiesler commented 2 years ago

We have repeatedly seen that pools suddenly change their parameters in a way that would redirect much/all delegator rewards to them (e.g. 3400 fix, 100% margin) - effectively stealing from folks who had put trust into that pool. Unbelievable, but happening!

Done

Run the Stake Pool Monitor

The monitor is configurable via these environment variables. All of which (except BLOCKFROST_API_KEY) are optional with defaults shown here.

When ticker list is UNDEFINED, the monitor selects the first MONITOR_TICKER_SIZE pools that are returned from Blockfrost. This is mainly for testing.

docker run -it --rm \
  -e BLOCKFROST_API_KEY="$BLOCKFROST_API_KEY" \
  -e BLOCKFROST_NETWORK="mainnet" \
  -e MONITOR_TICKER_LIST="UNDEFINED" \
  -e MONITOR_TICKER_SIZE=100 \
  -e MONITOR_MAX_FIXED=350000000 \
  -e MONITOR_MAX_FIXED_INCREASE=0.0 \
  -e MONITOR_MAX_MARGIN=0.03 \
  -e MONITOR_MAX_MARGIN_INCREASE=0.0 \
  -e MONITOR_ENDLESS=true \
  -e MONITOR_SLEEP=2000 \
