How to get Inbound Liquidity on the Lightning Network

There are several ways you can find inbound liquidity on LN.

1. Wait

If your node is up 24x7 and you have some outgoing channels, the network will connect to you if you simply wait.

However, it might take a couple of weeks to get a significant amount of incoming liquidity, and ideally you want your outgoing liquidity to match too.

Issues with the Blockchain Info API

The blockchain.info API for XPUBs only works with Legacy Bitcoin XPUBs, whereas their web interface confusingly works with Segwit as well.

I provide a couple solutions at the end, and we end up with three useful functions:

• legacy_wallet_balance
• segwit_wallet_balance
• segwit_wallet_balance_hack

Stuff I wish I'd known sooner about service workers

I recently had several days of extremely frustrating experiences with service workers. Here are a few things I've since learned which would have made my life much easier but which isn't particularly obvious from most of the blog posts and videos I've seen.

I'll add to this list over time – suggested additions welcome in the comments or via twitter.com/rich_harris.

Use Canary for development instead of Chrome stable

Chrome 51 has some pretty wild behaviour related to console.log in service workers. Canary doesn't, and it has a load of really good service worker related stuff in devtools.

JavaScript function hoisting by example

Below are many examples of function hoisting behavior in JavaScript. Ones marked as works successfuly print 'hi!' without errors.

To play around with these examples (recommended) clone them with git and execute them with e.g. node a.js

Notes on hoisting
