    Ordinals

    Ordinals

    Rare and exotic sats

    Ordinal theory concerns itself with satoshis, giving them individual identities and allowing them to be tracked, transferred, and imbued with meaning. Satoshis, not bitcoin, are the atomic, native currency of the Bitcoin network. One bitcoin can be sub-divided into 100,000,000 satoshis, but no further. Ordinal theory does not require a sidechain or token aside from Bitcoin, and can be used without any changes to the Bitcoin network.

    httplog

    Log outgoing HTTP requests in ruby

    Log outgoing HTTP requests made from your application. Helps with debugging pesky API error responses, or just generally understanding what's going on under the hood. In theory, it should also work with any library built on top of these. But the difference between theory and practice is bigger in practice than in theory. This is very much a development and debugging tool; it is not recommended to use this in a production environment as it is monkey-patching the respective HTTP implementations. You have been warned - use at your own risk. ...
