• Comment: The draft states in unambiguous terms that the concept is not notable. (Or, I guess it's the LLM used to generate the draft that states it.) bonadea contributions talk 16:00, 8 February 2026 (UTC)

Afterchain is a proposed cryptographic execution protocol designed to automate post-mortem transfers of digital assets. The protocol describes a system in which asset transfer remains reversible until a death event is externally verified, after which execution is triggered through smart contracts. Its design includes institutional verification mechanisms and a privacy-preserving beneficiary registry based on zero-knowledge cryptography.

Concept and purpose

The protocol is described as addressing how digital assets may be transferred after the death of a wallet holder without transferring private keys or custody to intermediaries. According to the author, Afterchain relies on cryptographic execution conditions rather than legal probate processes, allowing transfers to occur deterministically once predefined conditions are met.

Protocol design

The protocol specification describes a transfer vault mechanism in which digital assets are locked under a reversible state controlled by smart contracts. Until execution conditions are fulfilled, control over the assets remains with the original holder. Once a valid execution trigger is confirmed, smart contracts initiate the transfer of assets to predefined beneficiary addresses.

Death verification model

Death verification within the protocol is described as relying on institutional public-key infrastructure (PKI) mechanisms. The design references the use of certificate validation and revocation checks, combined with multiple external verification sources, before a death event is considered final. This multi-source approach is intended to reduce reliance on a single attestation authority.

Privacy and cryptography

The beneficiary registry is described as using zero-knowledge cryptographic techniques to conceal beneficiary identities prior to execution. According to the specification, zk-SNARK constructions are used to allow verification of registry integrity without revealing underlying beneficiary data. This design aims to preserve privacy while maintaining verifiability of execution conditions.

Research context

Academic research has explored mechanisms for transferring digital assets upon death, including blockchain-based inheritance schemes and cryptographic execution conditions. Studies in this area discuss challenges related to verification, privacy, cross-jurisdiction enforcement and trust minimisation in post-mortem digital asset transfer, providing broader context for inheritance-oriented protocols in decentralised systems.

Intellectual property

The protocol is described in an international patent application filed under the Patent Cooperation Treaty. As of 2025, the application has not yet been published.

Status

As of 2025, Afterchain has been described primarily in the author’s published work and associated technical documentation. Independent academic or journalistic evaluations of the protocol remain limited.
