Joseph Poon is a specific People coordinate in the Bitcoin knowledge graph. In practical terms, it identifies the subject described here: Co-author of the Lightning Network white paper, which combined payment channels, HTLCs and routed settlement into a second-layer design. This definition is narrower than promotional usage and should be read together with the implementation, date and evidence attached to the entry.
Co-author of the Lightning Network white paper, which combined payment channels, HTLCs and routed settlement into a second-layer design. The linked coordinates show the person's projects, ideas, disputes and historical effects.
Primary or authoritative records make these details checkable: Joseph Poon co-authored the 2016 Lightning Network paper with Thaddeus Dryja, describing a network of bidirectional payment channels using time-locked contracts and penalty mechanisms to settle beyond the base chain. They should be verified before using the coordinate in analysis.
The practical limit is: the paper is foundational but is not identical to today's BOLT specifications or every implementation; authorship does not imply sole invention, continuing maintenance or endorsement of later design choices. 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 Lightning Network, Payment Channel, HTLC, Lightning Routing, Bitcoin. The reverse links also lead from Tadge Dryja.
