in Re: [manrs-community] Implementing Decentralized RPKI with Blockchain Technology By seclists.org Published On :: Wed, 13 Nov 2024 16:19:13 GMT Posted by Brandon Z. on Nov 13Hi 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. Best, *Brandon Z.* HUIZE LTD www.huize.asia <https://huize.asia/>| www.ixp.su | Twitter... Full Article
in Re: Implementing Decentralized RPKI with Blockchain Technology By seclists.org Published On :: Wed, 13 Nov 2024 16:44:28 GMT Posted by Roman Tatarnikov on Nov 13Brandon, 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. Full Article
in Re: Implementing Decentralized RPKI with Blockchain Technology By seclists.org Published On :: Wed, 13 Nov 2024 16:47:26 GMT Posted by Francis Booth via NANOG on Nov 13In 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....

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,... Full Article

Rokeach via NANOG on Nov 13For 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... Full Article

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... Full Article

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.

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....
