First time posting here, please be gentle.
I'm doing a research project about blockchain timestamping. There are many
such projects, including the fantastic OpenTimestamps.
All of the projects essentially save some data in a block, and rely on the
block timestamp as a proof that this data existed
Your statements contradict each other.
This is not a question of whether it is a "huge" cost, but whether there
is an problem of incentive compatibility, which there is not. Miners
incur the opportunity cost of the space that they mine that does not
include the most optimal fees, which is equal in

It would be more accurate to say that the me

A perspective on block timestamp and opentimestamps can be found here:

The terms "simple ordering of blocks" and timestamp are essentially the
same thing.

That case would be stronger when there is no more subsidy, but we
