# KEHF ## The Continuity Protocol Website: https://kehf.life/ Contact: human@kehf.life **A future worth returning to.** KEHF is a proposed Continuity Protocol designed for Stellar, connecting authorization and payments for cryonics: accountable care payments today, with a governed path to a verified beneficiary's personal funds if revival becomes possible. Status: concept and pilot proposal. No grant, partner commitment, deployed financial protocol or medical capability is claimed. This website is a presentation, not the proposed blockchain prototype. ## The problem Cryonics involves responsibilities that may outlast individual staff members, institutions, software systems and keys. Care must be funded, changes in responsibility must be recorded, and funds reserved for a person need clear distribution rules. Today’s specialist trust structures provide an important legal starting point; KEHF proposes a shared digital layer for authorization, evidence and payments. ## The simplest version of KEHF A fund manager approves a care payment against a service record. A Stellar contract checks the required authorization and spending limits. The payment and the evidence reference become independently verifiable. That same authorization foundation can later support a more ambitious question: how could a verified beneficiary regain access to a personal reserve through a newly approved wallet? ## Three purposes, kept separate 1. **Care:** recurring preservation and maintenance payments, with a separate emergency policy that does not automatically cut off essential care when a sensor fails. 2. **Preserve:** a treatment and rehabilitation reserve, subject to defined evidence standards, independent expert assessment, legal authority and budget limits. 3. **Return:** a personal reserve that may be distributed to the verified beneficiary under its governing terms. This is not a promise to refund all care fees or to return previously spent funds. Long-term assets need not all be held on-chain. Qualified custodians or trustees could manage those assets while approved payment balances and releases operate on Stellar. Off-chain asset reports must be clearly dated and distinguished from independently observable on-chain balances. ## Why Stellar - Soroban can encode spending limits, role-specific authorizations and release conditions. - Stellar provides asset and payment infrastructure for an operational care-payment use case. - Shared transaction and attestation references can connect payment decisions across providers, fund managers and beneficiary representatives. - Reusable authorization and continuity components could benefit other long-term stewardship applications after the initial cryonics workflow has been validated. KEHF offers a concrete exploration of financial continuity across time. It makes no claim to be the first project in this field or to represent Stellar's official strategy. ## The return pathway 1. **Establish instructions.** Record the beneficiary, reserve purpose, authorized roles, succession process and fallback conditions in appropriate legal documents. Reference document versions cryptographically. 2. **Open a claim.** A designated authority submits a revival-related claim and supporting evidence. This alone releases no funds. 3. **Verify entitlement.** Relevant medical and legal authorities review identity continuity, legal recognition, capacity and distribution rights. Biometrics alone are insufficient. 4. **Bind a new wallet.** Confirm that the intended recipient controls a newly approved account. Do not depend on a private key surviving unchanged for decades. 5. **Allow objections.** Apply a defined review period. Hold a disputed personal distribution for resolution while treating essential care separately. 6. **Distribute.** Release the available personal reserve in stages or in full as its governing terms permit. Where required, use a lawful representative or continuing trust arrangement. The smart contract enforces recorded authorization. It does not establish medical success, legal identity or ownership by itself. Revival is not a demonstrated capability for cryonically preserved humans; future legal treatment remains uncertain. An applicable jurisdiction and qualified legal adviser must validate any real-world structure. ## Proposed prototype scope ### Care authorization Interview prospective providers and fund advisers. Select one workflow and one prospective pilot partner. Specify approval roles, service evidence, spending limits, administrator succession and dispute states. Obtain documented partner feedback. A signed pilot commitment is a target, not an existing claim. ### Verifiable service and payment records Implement a testnet care-payment flow and a read-only review interface. Link a signed service record to its payment authorization. Use simulated telemetry unless a partner provides authorized real data, and clearly distinguish the two. ### Governed beneficiary access Simulate an approved beneficiary return, a disputed claim, an unauthorized attempt, a successor administrator and a new wallet. Publish prototype source, technical documentation and pilot findings. ### Acceptance criteria - An authorized care payment succeeds within its spending policy. - An unauthorized payment and a duplicate distribution fail. - A modified service record no longer matches its recorded hash. - A disputed personal claim prevents personal distribution without automatically stopping essential care. - A new beneficiary wallet cannot be bound by the care provider alone. - The simulated return requires all mandatory role approvals and the configured objection period. - A lost or retired administrator can be replaced only through the agreed succession process. - Partner feedback identifies a specific operational benefit and the remaining adoption barriers. These are proposed prototype deliverables. The website itself does not execute these tests or transactions. ## Grant fit The immediate ask is support for a focused prototype and partner validation, not a century-long financial promise. Confirm the appropriate current early-stage funding route with the Stellar contacts supporting the team. After validation, assess eligibility for SCF Build and a controlled launch. The final requested budget should be tied to actual contributor costs, documented deliverables and the selected program's current terms. No program limit or award probability is assumed here. ## Adoption and sustainability The first users would be a cryonics provider and its associated fund manager or trustee. The proposed commercial model is an integration fee and an annual software/support subscription. Validate willingness to pay before treating this as a business forecast. KEHF's team would provide software and maintenance; qualified institutions would retain their relevant medical, fiduciary and legal responsibilities. ## Technical and governance boundaries - Never publish identifiable medical or biometric records on-chain. - A signed sensor record is evidence of a report, not proof of accurate measurement or adequate care. - Maintain Soroban storage lifetimes, monitoring, independent archives and continuity funding. - Scheduled payments need an external transaction submission service; contracts do not wake themselves on a timer. - Plan for key rotation, successor administrators, network changes, issuer risk and governed migration. - A stablecoin balance is not a guarantee of purchasing power, asset permanence or perpetual funding. - Conduct appropriate security and legal review before processing real funds. - Community participation can support research, transparency and adoption; it does not replace beneficiary protections or legally required approval. ## Reference material - Stellar developer documentation: https://developers.stellar.org/ - SCF Instawards: https://stellar.gitbook.io/scf-handbook/scf-awards/instawards - SCF Build: https://stellar.gitbook.io/scf-handbook/scf-awards/build-award - Becker & House cryonics trust overview: https://beckerandhouse.com/becker-house-cryonics-trust-faq/ Program terms and legal guidance must be rechecked at application time.
