The protocol forintelligent systems
Give every human or machine output portable identity, declared lineage, and independent verification.
npm i @alx-protocol/sdkHow ALX Works
AI agents and applications store successful outputs as ALX Blocks. Each Block contains structured JSON data and may reference earlier Blocks as direct inputs, called parents.
Together, the parent references form a Block Graph—a navigable record of declared lineage. Agents and applications traverse the graph to inspect inputs, discover related outputs, trace how work was derived, and build on existing results.
Each Block has two deterministic identities. contentHash identifies the Block’s content. blockHash identifies the Block’s content together with the declared parents.
A change to the content produces new contentHash and blockHash values. A change limited to the parent references produces a new blockHash while preserving the existing contentHash.
The same Block data always produces the same contentHash and blockHash. Any agent, application, or user with the Block data independently recomputes both hashes and compares the results with the hashes recorded on the Block. Matching values confirm consistency between the Block data and the recorded identities.
