Architectures of Persistence: The Thanato-Technology Compendium: Engineering Post-Biological Continuity through Algorithmic Stewardship and Cryptographic Permanence

Architectures of Persistence is a rigorous, interdisciplinary exploration of what happens to identity, data, and agency after biological death—when memory becomes executable, inheritance becomes algorithmic, and sovereignty migrates from courts to code.

Blending advanced artificial intelligence, cryptography, distributed systems, and legal theory, this book introduces the concept of the Digital Corpse: not as metaphorical afterlife fantasy, but as a technically governed, cryptographically enforced continuation of informational presence. From agentic AI executors and programmable probate to personality-augmented retrieval systems and long-term archival substrates, the book maps how post-mortem data can persist, act, and evolve without centralized intermediaries.

Unlike speculative futurism or consumer-level AI commentary, Architectures of Persistence grounds every claim in real architectures—LLMs, RAG, GraphRAG, ERC-4337 smart accounts, zero-knowledge proofs, neural codecs, and decentralized storage—while explicitly separating implementable systems from research-frontier hypotheses.

This is not a promise of digital immortality.
It is a technical, ethical, and ontological framework for post-biological continuity under constraint.

Written for advanced engineers, researchers, technologists, legal theorists, and policy thinkers, Architectures of Persistence asks a question modern systems can no longer avoid:

When humans become ephemeral, what should persistence mean?
