You can create a timelock smart contract requiring a future state of the blockchain to have been reached. Once that time has been reached, you can freely execute the function on the contract to retrieve the information. Tested it years ago, to lock up 1 ETH in essentially a CD for a year.
The trust is held in your own code implementation of the contract and that ETH will continue to exist and not be hard-forked or Shor'd or something.
