Jack Dorsey is a specific People coordinate in the Bitcoin knowledge graph. In practical terms, it identifies the subject described here: Block co-founder whose companies funded open-source Bitcoin development and built payments, mining and self-custody products. This definition is narrower than promotional usage and should be read together with the implementation, date and evidence attached to the entry.
Block co-founder whose companies funded open-source Bitcoin development and built payments, mining and self-custody products. The linked coordinates show the person's projects, ideas, disputes and historical effects.
Primary or authoritative records make these details checkable: Jack Dorsey co-founded Twitter and Block and has supported open Bitcoin development through Block initiatives including Spiral; current roles and product involvement should be taken from dated corporate disclosures. They should be verified before using the coordinate in analysis.
The practical limit is: funding projects or leading a company does not confer control over Bitcoin consensus; public statements are advocacy rather than protocol decisions, and corporate products have independent technical and commercial risks. A definition, office, chart pattern or published claim is not by itself a prediction or Bitcoin consensus rule.
For the clearest picture, read this entry together with Bitcoin, Lightning Network, Mining, Self-custody.
