I'm not claiming that this shows SCION can replace the respective parts of the network stack right now, and you're right that at a global scale this is still an unproven technology. But I would argue that a technology needs a certain level of matureness / is not "snake oil" if it is deployed in a heavily regulated and comparatively conservative sector such as banking.

Hmm, I'd disagree. The fact that Anapaya Systems (the for profit company mentioned) has the only commercial implementation/adjacent software is a problem, yes. But "snake oil" doesn't quite match up with the fact that SCION right now provides the backbone for the Swiss financial network moving 200 billion CHF each day [1], so at least some level of workable technology has to be there. And for no one to be taking it seriously, there's a decently long list of multinational ISPs at the very least taking steps towards offering SCION to customers [2] (e.g. British Telecom has expressed enough interest that they have various recent marketing videos on Anapaya's YouTube channel). Finally, I'm not sure what you mean regarding the "scummy inclusion of block chain / crypto" - as someone who has worked on SCION-based projects I never heard anything about this. Apparently a blockchain company invested in Anapaya, but that doesn't really change anything about the protocol itself, does it?

Indeed, he talks about BGP and SCION in the lectures. Sadly I think the lectures aren't available to non-students. What is available though are explanatory videos by him (Adrian Perrig) on the SCION website, where he talks about the issues BGP has: https://scion-architecture.net/pages/videos/

The tl;dw is that today's internet has comparatively poor availability, packet paths can be hijacked and there's little transparency in routing. SCION sets out to solve these problems, and has a few nice things in store, such as guaranteed bandwith between two hosts making DDoS attacks much less effective (COLIBRI QoS), or an incredibly high throughput packet filter (LightningFilter).

SCION looks very promising, and by now it has also been deployed in Switzerland's financial network, so it seems ready for production:

(Actually, the original creator of SCION teaches my CompNet course, which is pretty cool. His rants on BGP are quite legendary.)
