Legacy
PRIVATE
Prometheus protects information intended for another person after death or another formally verified legacy trigger.
The key problem is not simply preservation. It is preventing premature disclosure.
Governance:
- A beneficiary holding one share
- A professional release custodian holding another
- An independent contingency custodian holding the third
- Both custodian routes bound to the same verified release condition
After the trigger, the beneficiary can combine their share with an authorised release share. Before it, neither the beneficiary nor either individual custodian has sufficient information.
That is the meaningful advantage over the sealed envelope:
The envelope says: please do not open. Prometheus is designed to
say: you cannot read it yet.
A solicitor-held envelope depends upon:
- The paper surviving
- The envelope remaining intact
- The custodian not reading it
- The firm retaining the file
- The release instruction being followed correctly
- The contents remaining comprehensible
Prometheus adds:
- Threshold-enforced confidentiality
- No complete readable document held by one custodian
- Distributed physical redundancy
- Professionally verified sapphire records
- A defined release protocol
- Reduced dependence on the original provider
- The potential for open recovery
The release condition, successor custodians, evidence of death, contact
maintenance and failure procedures maintain a highly disciplined protocol.
LOOP
Loop is the time-staged or milestone-released version.
Examples include:
- An eighteenth or twenty-first birthday
- Graduation
- Marriage
- Retirement
- A future anniversary
- A child receiving a message from a parent
- A family history released at a selected time
- A future transfer of important instructions
Give it today. Reveal it when the time is right.
The recipient can physically possess the sapphire years before the message becomes readable. The object has already been part of their life, but its meaning remains protected until the intended milestone.
Unlike the main Prometheus: protocol which is triggered by death, incapacity or verified legacy event, Loop works to a known date, age or affirmative life milestone.
