Our lives and actions and sins and good deeds will be documented in the blockchain.

There will be no hiding it. It remains as abstract as the amount of time that it takes to read it. Probably with a Unix timestamp down to the second. If the homework blockchain gets updated 5 minutes before midnight all at once then everyone will know. It muts. Otherwise, reality will simply not be as it is.

Perhaps it will provide humanity the opportunity to muse on whether the ends justify the means.
