Lightning wallet details

  • Fully autonomous, uses segwit-enabled bitcoinj for Bitcoin stuff and custom library for Lightning stuff (which is heavily inspired by project).

  • Can not route third party Lightning payments. Can send and receive your payments, but receiving is only on testnet for now since receiving of Lightning payments on mainnet from lite clients like mine would need to rely on a special WatchTower server and protocol devs hasn't started working on it yet.

  • Uses a special server called Olympus which carries out various maintenance tasks, more details here: The most interesting thing about Olympus is storage tokens (NOT AN ICO!) which is, I believe, the best way to scale and sustain my project, you can read more on them here:

  • Allows for one active payment channel at a time. The reasons for this are purely non-technical: such an approach makes wallet UX more user-friendly and saves on Bitcoin fees, the only downside is you won't be able to send Lightning payments and will have to open a new channel if your only peer becomes permanently offline. But in my view Lightning will quickly evolve into a network of professional, very well connected and always online nodes which would compete on routing fees so this should not be a problem.

I find an old Mycellium PDF backup file with the QR codes for the private key and the address. And just as quickly a see the unfilled section of the 15 character password. Crap. I was 99.9% sure there was bitcoin in them folds of that wallet. But how much? I couldn’t remember. I knew a friend…
