Block Protocol

The Block Protocol is an open standard for the development and zero-knowledge interoperability of modular user interface components (aka. blocks).

Based around the Semtype standard for universal, composable types, the Block Protocol was originally developed for use as part of the open-source HASH platform. As part of this it supports high-quality, bug-free user and AI-defined interfaces to be built atop semantic data.
