In particular, the verifier can validate</div><div class="">a certificate chain on its local copy of the blochain without any</div><div class="">network access. Details can be found in this <a href="https://pomcor.com/2016/10/25/implementing-a-pki-on-a-blockchain/" class="">blog post</a> and in Section</div><div class="">3 of <a href="https://pomcor.com/techreports/BlockchainPKI.pdf" class="">this paper</a>.
