Rusty Russell’s Quiet Corner of The Internet

This is an “eat your veggies!”

After the previous aside on a gossip bug, I realized I should do a tour of each daemon.

I stumbled over a bug while doing some work on gossipd, so I decided to record myself tracking it down.

This post is all about tal repostory, which is the CCAN module which I consider compulsory for any program which ever explicitly frees memory (you can write some very complex programs which don’t do that, FWIW!).

This post is all about the CCAN repostory, which contains all kinds of useful C routines which we use all over Core Lightning.

This is the start of a one-per-workday video series, introducing Core Lightning Development to already-fluent C programmers.

In my previous posts I’ve been carefully considering what bitcoin Script improvements we might want if we had introspection.

BIP-341 defines Taproot outputs as either a single key, or a key and some script info.

As I explore the use of Bitcoin Script for introspection, I am not overly concerned with total script size, because if common usage patterns emerge those can be soft-forked into new opcodes, or new address types.
