Ethereum Can Quantum-Proof Accounts For Just 7 Cents, Says Foundation's Kohaku Project Lead

Authored by Zoltan Verdai via CoinTelegraph.com,

Ethereum could begin adding post-quantum protections to accounts for as little as $0.07, without waiting for a hard fork, according to the Ethereum Foundation's Kohaku project lead Nicolas Consigny.

In a Saturday X post, Consigny shared a paper proposing a cheaper way for Ethereum users to protect their accounts against future quantum-computing threats. The approach adapts SPHINCS+, a post-quantum signature standard developed by the US National Institute of Standards and Technology, to work more efficiently on Ethereum.

Dubbed “SPHINCS-,” the proposal aims to reduce onchain verification costs without requiring a protocol change or precompile. Consigny described SPHINCS- as a bridge toward a future post-quantum signature system dubbed “leanSPHINCS,” which aims to further reduce verification costs through aggregation.

The proposal seeks to address the long-term risk of a quantum threat to Ethereum's Elliptic Curve Digital Signature Algorithm with a cost-efficient solution that may be deployed before a dedicated hard fork is developed.

Future quantum computing threats stirs crypto community

In April, post-quantum startup Project Eleven awarded a prize to researcher Giancarlo Lelli for using a quantum computer to break a 15-bit elliptic-curve key.

Bitcoin’s keys are 256 bits long, significantly larger than the 15-bit key Lelli managed to crack. He derived the private key from a public key paired to it, using a variant of Shor’s algorithm, a quantum computing technique that theoretically poses a threat to the type of cryptography used by Bitcoin.

According to Glassnode, about 1.92 million Bitcoin, representing nearly 10% of the total supply, are considered “structurally unsafe” in a future quantum attack scenario. Another 4.12 million BTC, or 20.6% of the supply, are classified as “operationally unsafe” due to key or address management practices.

The analytics company estimates that the remaining 69.8% of the supply, or 13.99 million Bitcoin, remains unexposed to a quantum computing threat, broadly in line with Ark Invest’s March estimate that 65% of the supply was safe.

Space: The Now Frontier And The AI Revolution

By Peter Tchir of Academy Securities

Space: The Now Frontier & The AI Revolution

Academy will tackle any details on a deal with Iran via a SITREP and a podcast, once (if) details are made  available. 

After last Friday’s extreme move (More Than Rates Moving Markets) we had a relatively tame week with the S&P and Nasdaq both gaining around 0.7%, but neither getting back to their highs of the week, set on Tuesday. Yields drifted moderately lower on the week, primarily on the back of steep declines in the price of oil (though I do feel the need to point out the Jan 2027 WTI contract, which I’ve been focusing on, is still at $76.1, barely one dollar lower than where it closed last Friday – I remain in the higher for longer camp). Credit spreads remain firm and the asset class remains “boring” which is a good thing! 

Now let’s address two bigger picture issues that have been taking up a lot of time during recent client calls and visits. Space and AI. 

Space: The Now Frontier 

Space: The Final Frontier still gives me the chills! The excitement of exploration! The IPO of SpaceX and all the discussion it has created has brought back that feeling. 

A colony of 1 million people on Mars! I love the concept! I have 0 opinion on whether the number of shares that Musk gets for achieving that target is the right number, but I love having that concept out there. 

Think big:! This concept floating around, and now documented into Wall Street, excites me. On the back of Artemis II and the planned lunar landings, there is a lot of potential for new discoveries. 

On a more practical (or near-term outlook) it can lead to AI and Data Centers in space. New sources of energy and potentially other materials. 

But there are also important National Security elements that are gaining more attention. 

Many members of Academy’s Geopolitical Intelligence Group lament that we have been “soft” on space. That we have ignored the real dangers to national security by not focusing on space as much as we need to. While the Space Force was a step in the right direction, many argue that we are behind (some might argue woefully behind) where we should be in terms of ensuring that space is safe and our interests are protected! 

At the simple and on the not controversial end of the spectrum, is “space junk.” The debris in orbit is increasing. While not currently posing a risk, it is something that should be addressed better than it has been. 

What about GPS and communications? I’m not sure that I could walk to the corner store without using some map app. The working assumption that “no one is interested in disrupting GPS” may be naïve? While at least 95% of communication remains “terrestrial” (fiber optic cables, undersea cables, cell towers, etc.) space will become increasingly important to communications. While it might not be “mission critical” to protect the communications equipment in space today, it could be.

Who will control discoveries? 

Let’s say we find some vital resources on the moon (seems the most likely “surprise” that could occur in the near future). Who will control that material? 

• At best, the discoverer and those with the capabilities to take advantage of such material.  
• At worst, might is right. 

We expect this administration, and future administrations, will spend more on space to support National Security. This is a bipartisan issue as we think about the myriad of possibilities for space. Not just the good and altruistic possibilities, but also about the risk that some other country doesn’t share such a cooperative spirit about the future of space. 

This is by no means, “closing the barn door after the horses have run out,” but it is something that deserves more serious attention and money going forward.  

The national security elements are in addition to the commercial opportunities that will be funded as corporations rush to harness the potential! 

If waking up to a $2.1 trillion market cap (and the first trillionaire) doesn’t motivate entrepreneurial and capitalistic spirits, then I should just give up this job, because it would go against everything I understand about capitalism! 

Space may be the “final frontier” but it is also the “now” frontier, which is incredibly exciting! 

The AI Revolution 

Let’s get the hard part over, and start with this image: 

This image is meant to grab your attention, if not create some shock value. Yes, I used AI (ChatGPT in this case) to create an image of modern-day workers storming a data center like villagers in the old days. It isn’t perfect, but it is about a zillion times better than I could do on my own. 

My current thinking on AI: 

• It is crucial to have the lead in this technology from a National Security standpoint.
  • Maybe I’m falling into a trap where everything looks like a nail, when you only have a hammer, as I spend so much time with the Geopolitical Intelligence Group, but I do believe that the AI Race and the Data Race are real and it is crucial to stay ahead in these races. I cannot tell whether it is one race or two races that are similar, but that doesn’t really make a difference, so we will ignore that technicality for now. 
• We are all trying to implement AI into our routines, with varying amounts of success. 
  • “Traditional” search (if you can call something that didn’t exist when I was born, “traditional”) has been almost fully taken over by AI. No longer are we just getting pointed to links and websites as search results. We now get the answers we presumably would have gotten by going to those links up front. 
  • Sometimes we are “shocked” by the results of AI. 
    • Sometimes those “shocks” are good – like the image delivered above. 
    • Sometimes those “shocks” raise eyebrows – like how could it make up a ticker?  Or not find the current version of what we were trying to solve. Ending up in a level of frustration over the need to correct some “slop” after spending money to generate that “slop” in the first place. At the back of your mind, you cannot help but wonder what you might have missed, in prior instances of using AI.
  • I think a lot about the Gell-Mann Amnesia Effect (the ad that popped up for me on this link was for ShipSticks - got to give the ad agencies some credit for that). 
• We have moved beyond “generic” questions about AI and into wanting real world examples and case studies. 
  • We are in the phase of trying to figure out “if it is worth it.” Not just figuring out how much time we saved (after applying our own touches) but we are also considering what we didn’t learn by going down the AI path. 
  • With the prices rising for usage, it is becoming easier to think about AI in a “traditional” cost versus benefit framework. Presumably (based on market valuations), AI is going to look very cheap. 

If my current thinking is generally positive on AI and I truly believe it is crucial for security, then why show a picture depicting the AI Revolution as people storming a data center? 

• Anthropic Disables Mythos 5 and Fable 5. This was done to comply with the U.S. government’s demands. National Security front and center. I will admit, there is a part of me that thinks this might be the best “velvet rope” marketing campaign ever. It is so powerful that you can’t use it, just makes people want to use it. But it is only a part of me that thinks that. The larger and less juvenile side of me thinks there are real security risks being unleashed.
  • It is difficult to undo discoveries. Now that everyone knows that this sort of AI has been developed, people will try to replicate it. How long before someone else has this tech and uses it against us (or you or me). We are going to have to ramp up our National Security Policy around data, chips, and AI at lightning speed! 
  • There will be (and there already is) an element of I Told You So. Those who don’t want AI to succeed will use this to try to slow the development of AI. Again, just because we slow down and add stricter guardrails doesn’t mean those who want to do us harm would follow suit (they wouldn’t, they would just smile at the opportunity being given to them). 
• Remember the “viral” report on potential job losses from AI? Wall Street may have moved on, but not everyone in the country has forgotten about the fear it stoked in them (primarily around their own jobs and careers). While our Are We The Horses? in the buggy whip story hasn’t gone viral, it has gotten some attention. Lisa Abramowicz asked me about it during my interview last week and has mentioned it several times. I recently came across another report also asking those questions. Fear of job loss is real. 
  • Add in robotics, and job loss fears mount even higher.
• Electricity costs. People don’t love the looks of data centers (one friend pointed out recently, that while driving at 79 mph, it took 3 minutes to drive by a data center construction site). Water issues are there too, but for now it is the electricity consumption that bothers/scares people the most.

The biggest risk I see to the AI industry in the U.S. is that a political movement captures the angst surrounding the business and uses that sentiment to win elections and slow or even derail AI in the country. 

We are not there yet, but the industry has to focus on heading this risk off at the pass. 

• We’ve seen a “softer” tone out of some AI executives, particularly trying to flip the narrative to job creation from AI rather than job losses. 
• The companies developing the AI and Data Centers are doing a much better job on the electricity side of things and will continue to do that. 
• While it is probably important to lobby in D.C., I think it is equally important (and possibly more important) to maintain/win in the court of public opinion. 

My picture is unlikely to gain traction (no one uses torches anyways), but that sentiment is bubbling just below the surface and I think tackling it head on is one thing that AI needs to do. The national security focus helps, but is not in itself enough. 

Bottom Line 

I think I need to watch some Star Trek episodes on upcoming flights.I am very excited about space and think that sentiment is widely held. I am largely excited about AI but think there is a real risk of political backlash if the industry lets fears seep into the populace at large and some politicians harness that fear. 

Hopefully, we have details on Iran and they are good and we can move on from that topic.
