Han Qin is an independent philosopher, researcher, and multilingual content creator. He is the author of the Self-as-an-End (SAE) theory series — a body of work developed over eighteen years in collaboration with philosopher Zesi Chen, and published in accelerated form beginning in late 2025.
Han publishes scholarly work here and multilingual essays at Non Dubito (nondubito.net). The two sites serve different reading modes: self-as-an-end.net is the open academic corpus for SAE, while Non Dubito hosts essays, cultural writing, and more literary treatments of philosophical ideas across languages.
Han is Co-founder and CEO of Jarsy, a tokenization platform building compliant blockchain-based infrastructure for global investors to access alternative assets. Jarsy is backed by Breyer Capital, Karman Ventures (Travis Kalanick's fund), and notable angels, and operates under Reg D 506(b) and Reg S.
Prior to Jarsy, Han worked as an engineer at Facebook, Uber, and Afterpay. He holds a PhD background in computer science with expertise in ontology, semantic mapping, and knowledge hierarchies.
The Self-as-an-End framework originated from a practical frustration with Silicon Valley's instrumental rationality — the culture that asks "how fast?" without asking "toward what end?" The framework's name emerged through an unexpected path: a ChatGPT misunderstanding during a conversation about Demon Slayer, passing through an essay that eventually crystallized eighteen years of intellectual development into a named theoretical system.
The framework's working language is the chisel-construct cycle (凿构循环) and the sixteen-level DD sequence (1DD–16DD), preceded by Hundun (浑沌) at 0D. At 16DD, mutual non dubito (双向不疑) names the intersubjective encounter of two subjects who cannot be reduced to or absorbed by one another. SAE treats this sequence as a working structure whose steps, branches, and jurisdiction remain open to continuing interrogation, not as an automatically executing deduction.
The end/acc (End-Directed Accelerationism) manifesto is the framework's public-facing counterpoint to e/acc, asking not "how fast?" but "how right?" — where rightness is defined by escape velocity exceeding colonization velocity.
