I have a question to all crypto-guru here.
Is it technically possible to build a service ( or even a serverless/decentralised service, so that it can't be attacked/blocked/ddosed and without human failure attitude ) that give the possibility to leave a message somewhere and maintaining it encrypted until a certain date? ( example: bitcoinclock.com )
The service admins also must NOT be able to read this message until this date.
The user write the message and set a date.
Then the service give a link that the user can share everywhere he wants.
It would be good if the user is also able to stop it if it isn't needed anymore.
A soldier/spy that wants to leave a message to the community before a dangerous mission.
If he survive, he needs to be able to stop this crypto-testament to decrypt itself.
Do you like this idea?
