PROOF OF WORK, A PICTORIAL ESSAY Proof of Work, a pictorial essay. In the modern nation state, courts ("justice") operate with the threat of violence. The exact way a dispute is settled varies (jury, single judge, etc.), but the "finality" of the resolution they provide is based on the fact that the state asserts the final say, and if you don't agree, it doesn't matter, because they have men with guns.

This site was mostly used to house my blog (see "waxwing's Blog" here); I will repopulate the site with the former articles. Please be aware that there will be some bad formatting due to difficulties with re-instantiating the site on a new platform; some images and some special characters will be formatted wrongly. At some point I may re-instantiate also the public orderbook watcher instance but this should be of little interest since it can be run trivially, locally with an install of Joinmarket (you don't need Bitcoin Core for that). Donations for my work gratefully received here
