Re: [manrs-community] Implementing Decentralized RPKI with Blockchain Technology

Posted by Brandon Z. on Nov 13

Hi guys,

In technical terms, RIRs can indeed configure IPs to become RPKI invalid.
However, my point is not to remove RPKI but to make it invalid.

This could happen; for example, RIPE was required to remove all IRRs
related to Russia (I'm glad RIPE has not done this).

Decentralization can address this issue; it's not just a hype concept.

Brandon, I blockchain and BGP were discussed on NANOG some years ago, back
when the deployment of RPKI was brought up. Short answer - it won't solve jack
and will use tons of computation power.

I'm not really going to go into details, but essentially adding a band-aid
instead of adopting RPKI and addressing the issues with RIR is not the best
course of action.

In such a scenario I’d argue for less automation to prevent such a rogue RIR from being able to cause such a disruption
to the Internet.

To expand on what Tom mentioned, Networks are not yet rejecting announcements with a NotFound validation. Even if such
an event did occur I’d be willing to bet most network operators are going to be leaning on their interpersonal
connections rather than automation to reestablish peering with networks....

Hi Brandon,

That's not how blockchain works. Validation is time-bound and
irrevocable. Only the current key-holder can transfer the validated
material to another entity. Effecting such transfers requires minimal
computation, on the order of a few HTTPS transfers.

Under block chain, an RIR would not be able to revoke number
resources, not even for non-payment or fraud. And if the keys
associated with an address block were lost or stolen,...

For what it's worth, this is quite implementation specific and leaves a lot of room for intentional and appropriate
design decisions. Custom smart contract (think "decentralized program") code could be used to enable the functionality
desired for an RIR, without other functionality.
Let's extrapolate: An RIR could use smart contracts with immutable code to allow an entity to register a specific block
and retain certain...

Incorrect.

If the RIR revokes the resource certificate used to sign the ROA, the ROA
is also then revoked. Validator software will then remove the VRPs that had
been created from that previously valid ROA. If there are no other VRPs
that cover the BGP message parameters, the validator will return NOTFOUND.

If the RIR refused to publish or deleted the ROA, validators will
eventually delete them, which also removes the VRP previously created. If...

Not really. If it's technically feasible to override or roll back
transactions, you've violated one of the central tenets of block
chain. You can design a system that allows transactions to be rolled
back or changed by a central authority but the result would not be a
block chain and would not have the desired characteristic of
resistance against government compulsion.

transactions, you've violated one of the central tenets of block

To be clear, I did not state such. Ownership can be transferred by smart contract. This does not violate a core tenet
of blockchains and is a key feature of almost all blockchains which still exhibit signs of life.

If the RIR can institute a revocation via smart contract, for any
reason, then you haven't achieved any resilience against government
compulsion applied to the RIR, which was Brandon's reason for
considering blockchain in the first place.

Thanks for raising this topic. In all the rush to deploy RPKI I fear these issues are not talked
about enough.

A variant of this could make some sense, the issue is that it doesn't do you a whole lot of good to
have a local RPKI anchor that you and your local community look to if the global internet community
isn't looking at it - sure, your IPs are routable to a few of your friends, but they can't reach
Google...oops....

Tom,

Something I’ve been curious about for some time: since deployment of RPKI is (mostly) hosted by the RIRs and
ultimately, the RIRs control the validation chain, what would happen if the RIR creates (or, if you prefer, is directed
by court order to create) INVALIDs?
