Day 3: CLI or Polar? Learnt Lightning Both the Hard and the Easy Way

previous day's adventure

Some people learn to swim by reading a book. Others get pushed into the deep end. Today was both. Somewhere in the middle, a lifeguard(Polar) showed up.

Today the goal was simple on paper. Learn the Lightning Network, understand how it works and continue with the setup. The CLI came first. No shortcuts. No GUIs. Just a terminal and a lot of commands.

The LND binaries for version 0.20.1-beta were downloaded and extracted. After that, lnd and lncli were moved into /usr/local/bin so the system could actually find them.

Then came the first real friction point.
