Monero software upgrade (Boron Butterfly)

Network update is planned around in March. In the upcoming release of the Monero software Boron Butterfly [1] (v0.14.0) will be added a new PoW based on Cryptonight-R, also will be added a new block weight algorithm, and introduces a slightly more efficient RingCT format. Thus node and mining software should be updated before.

I am documenting my steps how I upgraded node sofware. I am running Ubuntu 18.04 [2]. Assuming ubuntu operating system is ready. I am going to download the monero software [3] particularly for my ubuntu linux x64 version [4]

wget https://downloads.getmonero.org/cli/linux64
tar xvf linux64
mv monero* ~/bin
rm linux64

After make my own bin directory, I edited crontab for automation.

crontab -e

Append the line.

@reboot ~/bin/monerod --detach --rpc-bind-ip 0.0.0.0 --rpc-bind-port 18081 --restricted-rpc --confirm-external-bind

After “detach” the rest of arguments are optional, but that gives an opportunitty to use as a remote node for “Monero GUI”. Local machine doesn’t need to have all blockchain and save around 70GB of disk space.

Assuming that my firewall is ready, I can reboot machine and startup script should kick in. If It’s a first time need to leave it for about one day in order to download and verify full blockchain.
