That's a job for ordinary PKI. Any time you have a trusted central
authority to serve as an anchor, ordinary PKI works fine. The RIRs serve as
anchors for who has the right to authorize which prefixes.
A harder task is validating whether your peer is part of a legitimate AS
path to that origin. It's not obvious to me that blockchain could help
solve that problem, but it's at least a problem that isn't solved by
Now, if we wanted to replace the RIRs and allow people to self-assign IPv6
addresses out of ULA space which we'd then honor in the global BGP table,
blockchain could have a role.
