Then you don't want blockchain-based technology. Remember, the data is still on the chain, and can never be deleted - the paper is pretty clear about it.

So in a year's time if the 3rd party contacts the archeologist, they can arrange to truncate the chain and unseal the key. Yes, the archeologist is not going to get paid on-chain by the protocol, but the secret is still out.

Really looks like the bank's safe deposit is a much better solution if your data is valuable.

I still think you might be throwing the baby out with the bathwater; though I admit there's a lot more bathwater than baby, especially when compared with first glance.
