I guess the attack could still be used for denial of service.
RPKI only secures the ownership information of a given prefix, not the path to that prefix. Under RPKI, an attacker can still claim to be on the path to a victim AS, and get the victim's traffic sent to it.
The solution to this was supposed to be BGPSec, but it's widely seen as un-deployable.

Proof-carrying data has come a long way in the last 10 years.
EDIT: you would still need RPKI, but not BGPSec
It feels like we’ve secured the part that’s easiest to validate, not necessarily the part that matters most.

This sounds "obviously bad" but the intricacies of routing aren't really my field, could you expand on why this is bad? (i.e. what specific bad things does it enable)
The attacker can impersonate the victim, get a valid x509 certificate issued to it, and create a perfect replica of their website/api/whatever.
The attacker can perform a man-in-the-middle attack on the victim - record traffic, inject traffic, manipulate traffic, etc.
The attacker can just deny access to the victim - just drop packets meant for the victim.
How many major isps would we want to implement it to be "safe" and what would that look like? Is this a regional thing? They've only listed 4 unsafe ones on the site and that doesn't seem like a major issue, but maybe they're very large somewhere.
It would be "enough" if all the major transit ISPs did it and it would be helpful if all the major residential ISPs did it. If non-RPKI routes can't propagate through transit ISPs, that makes it a much less useful thing to do.
They've listed way more than 4 (and those 4 are also massive), click "Show all".
There's 254 operators marked as unsafe.
It's not on the list so imagine there is a fair few missing, would be neat to have a table you could filter by country, provider type (cloud/isp etc) based on real results from users.
edit: there's a show all button to expand the table
But on some level that's like assuming the reason the guy with the handgun is on your plane is that he's a sky marshal and not that some idiot let a concealed handgun through security. I mean, sure, maybe, but, maybe not.
Without asking it's just a guess and I haven't asked. Maybe I should.
T-Mobile USA, AS21928 does NOT implement BGP safelyMajor ISPs like British Telecom (core UK telephony), NTT Docomo (Japan), Vodafone Espana (showing that Vodafone isn't doing it globally), Starlink (showing it's not a old tech problem), Rogers (US ISP) are listed unsafe.
I think the 31 is a misleadingly positive picture.
Free SAS ISP signed unsafe

Sure the swiss have their toy but no one is taking it seriously.

As for BT - they're just one broadband ISP operating primarily in a single country. I don't see that moving the needle - you're missing CDNs, traditional large scale "tier 1s" and cloud or large hosting networks.
RPKI got to where it is today through community engagement by folks like Job S. and others - hitting the conferences, direct engagement with operators and raising the bar from a software quality and standards perspective - which still continues today. That's how you get the internet to adopt something that is considered the new normal.
As for your ISP list - I know there are networks listed there that aren't running scion in a production capacity (perhaps you can run scion in a virtualized environment on top of them which is different than those companies running it on their production network).
As for the block chain - it was all the Sui stuff.
This is a meaningless benchmark - for a small group of trusted big enterprises with insurance policies and mutually signed contracts you could've just as well used OSPF with zero filters.
The benchmark would be adoption by an actual large number of parties that don't/can't talk to eachother spread across the world. With a large chunk of them being malicious or incompetent to the point of being effectively malicious.
SCION is practically speaking proprietary, and has 1 and maybe a half implementations. I have a laundry list of real problems with SCION but SCION feels like one of those entities that would get quite legal-ey if discussed publicly.
So the benefit of changing out all that infrastucture needs to be much higher than the cost.
