Decentralized identifiers (DIDs) are a new type of identifier that enables verifiable, decentralized digital identity. A DID refers to any subject (e.g., a person, organization, thing, data model, abstract entity, etc.) as determined by the controller of the DID. In contrast to typical, federated identifiers, DIDs have been designed so that they may be decoupled from centralized registries, identity providers, and certificate authorities. Specifically, while other parties might be used to help enable the discovery of information related to a DID, the design enables the controller of a DID to prove control over it without requiring permission from any other party. DIDs are URIs that associate a DID subject with a DID document allowing trustable interactions associated with that subject.

I've finally gotten around to trying to scan the barcodes on all of my books. I'm using Library Thing, even though it is trying really hard to be some kind of Clown-based gamified "goodreads" fucktangle when all I want is a local catalog. Anyway, what's the deal with every single paperback book released in the 1990s having a barcode on the back cover that is useless for scanning? Most of the ...
