Consider supporting sequential aggregate signatures #3

Open eternaleye opened 6 years ago

eternaleye commented 6 years ago

The README describes how threshold signatures attesting to the validity of blocks will be needed for some applications.

However, a Merkelized chain of blocks is still subject to truncation attacks, which can be mitigated with sequential aggregate signatures as described in this paper.

Interesting! Thanks for the link. I think for now this crate will remain independent of any kind of signature collation. Unjustified blocks can easily be mapped to something which produces trustworthy justifications.
