Henceforth Bitcoin Limited

About

Native iOS apps by Henry Hudson. No ads, no tracking SDKs that do not earn their keep, and an engineering stance that treats the device as the source of truth.

Three products share one spine: local snapshot first, network only as newer evidence. That is how the Henceforth wallet refuses to shrink a verified balance because a chain service was briefly stale, and how Hansard renders every constituency with the radio off.

The stack language is FORTH — small words, a LIFO pile, and the same shape as Bitcoin Script. SwiftBSV is the open-source Swift package under the wallet. Leo Brodie’s Starting FORTH and Thinking FORTH still set the teaching tone for the Learn series.
