Upgrading Geth to 1.8.20 due to constantinople hardfork
On January 9th my Rinkeby node got out of sync with errors such as: invalid gas used, BAD BLOCK 3660663, Synchronisation failed as I forgot to upgrade my Geth so I wrote a little blog post of the upgrade process.
Have a great Sunday Ethereum folks!
