Indeed! This can be done for all public documents, efficiently, cost effectively, without taking away valuable block space from other transactions. Also, if on Bitcoin, no need to use other chains since security has already been maximized.

“After the first round of elections, the Mission highlighted the use of blockchain technology to preserve the inalterability of the tally sheets, which could be downloaded directly by the population, and that this was indeed what happened in the post-electoral period, which helped refute queries raised by certain actors.
