How to check if your PIVX wallet has forked.

I don't know how or why your wallet can fork into its own chain if you are staking. Know that it can happen and a symptom of that situation is that you'll start to receive high rewards in short periods of time.

To verify that your wallet is still on the main chain you have to get the block hash for the latest block in your chain and compare it with the block hash found for that same block in a block explorer. Step by step instructions found here: My staking or masternode reward is much higher than expected.

I wrote a script to automate that process, here it is:

#!/bin/bash
# saved as did-it-fork.sh

set -e

pivxcli=~/.pivx/pivx-cli

function getBlockNumber() {
  $pivxcli getinfo | grep blocks | sed "s/.*: \([0-9]\+\).*/\1/"
}

function getLocalBlockHash() {
  $pivxcli getblockhash $1
}

function getRemoteBlockHash() {
  curl -# 'http://pivxscan.io/api/getblockhash?index='$1
}

blockNumber=`getBlockNumber`
localBlockHash=`getLocalBlockHash $blockNumber`
remoteBlockHash=`getRemoteBlockHash $blockNumber`

echo '            block: '$blockNumber
echo ' block hash local: '$localBlockHash
echo 'block hash remote: '$remoteBlockHash

if [ $localBlockHash == $remoteBlockHash ]; then
  echo 'GOOD: still on main'
else
  echo 'BAD: you are on a fork, got to re-sync'
fi

exit 0

Usage example:

./did-it-fork.sh 
######################################################################## 100.0%
            block: 757941
 block hash local: 61e98dad1653790d074b82633f57753ac80ac7e7a7098355cbdb99b0be8cf671
block hash remote: 61e98dad1653790d074b82633f57753ac80ac7e7a7098355cbdb99b0be8cf671
             GOOD: still on main
