We are trying to explore this at http://www.BlockchainCommoms.com but it is a real challenge. Current patron models aren’t sustainable during price drops or even just very stable times (see Heartbleed). Maybe a UASF-like culture of not validating miners who don’t support infrastructure? https://twitter.com/nlw/status/1091319914214948864

I’m butthurt that that as as ecosystem we’ve not discovered a sustainable solution to what is a large systemic risk. I did well by SSL/TLS but only because I was in early. Some pattern is true in blockchain. 10 years from now you can’t rely on support from HODLing devs.

Though I believe the loss of keys in this case to be a ruse, from my research for the #SmartCustody series of workshops a lot of what is being said by digital asset exchanges & custodians is security theater. Proof-of-Reserve is a good tool, but customers need demand more.
Ultimately I think this is the direction that we need to head, with the caveat is that the culture & incentives need to be attractive enough that people voluntarily tax themselves rather than move to a fork. Another is majority voting governance is problematic, we can do better. https://twitter.com/mayazi/status/1092333139786117121

If you are in Toronto this meetup is likely to be interesting. #SystemChange theory & Christopher Alexander’s pattern language thoughts are oddly connected to blockchain design & governance. Satoshi appears to have been a multi-disciplinarian and you should be too. [https://twitter.com/zaid__khan/status/1094383146081017856](https://twitter.com/zaid__khan/status/1094383146081017856)
An interdisciplinary skill that I believe Satoshi had were the habits of a system thinker. Brief summary of habits/sub-skills of a systems thinker are at http://www.watersfoundation.org/wp-content/uploads/2018/03/HOST_Blue-1.pdf and more free materials from the Waters Foundation.
A skill & tool related to System Thinking are Causal Loop Diagrams. To date I’ve never seen anything that quite does as well at demonstrating some of the paradoxical outcomes in some systems. Here is an example of Tragedy of the Commons (though it is more effective animated):
https://twitter.com/christophera/status/1094463573529583616?s=21
When I was faculty in the MBA for Sustainable Systems at BGI/Pinchot/Presidio, the students had had extensive training in use of causal loop diagramming & analysis. I’ve not found any full tutorials online but there is a good into at https://systemsandus.com/2012/08/15/learn-to-read-clds/
Some other Systems Thinking tools are described in this post from The Systems Thinker (site for which has a lot of other good resources): https://thesystemsthinker.com/a-palette-of-systems-thinking-tools/
Here is an example of a causal loop diagram for the Israel-Palestine Conflict, as well as an intervention leverage points implied by the model. https://thesystemsthinker.com/a-systemic-view-of-the-israeli-palestinian-conflict/
This is a causal loop diagram by Army Staff on the Afghan conflict. Gen. McChrystal joked “When we understand that slide, we’ll have won the war”, and since has been labeled “worst powerpoint slide”. However, as I know CLDs, I actually find it powerful. https://www.nytimes.com/2010/04/27/world/27powerpoint.html
I would really like to see the blockchain mechanism/incentive design communities, as well as the decentralized governance communities learn causal loop diagramming. As these can be incredibly complex systems with non-linear or even paradoxical effects, CLDs can help spot them.

I had to use a VM on my mac to run the rather poor UI of the expensive CLD tool we used during the MBA program. I was the VMware image but it doesn’t work anymore. #bitrot I’m unclear on what is best CLD tool today.

Vensim looks intriguing. They offer a free non-commercial & educational version and support a Mac version. They also support random inputs, monte-carlo optimization, continuous & discrete arrays, and more. https://vensim.com/free-download/

I disagree. The problem is that 20th century styles of learning taught us to simplify problems by breaking them down to bite-sized. But all the problems that can be solved that way have been solved. What remains are complex problems, which we have no tolerance for learning to fix
Replying to @oliverbeige
Causal Loop Diagrams have their limits, but I’ve seen little to replace them for a dive into complexity. I would love better tools, and once tried to start a company to build them, but marketplace (and VCs) wanted simplicity & less learning curve to understand. Not sure possible.

I personally have an aversion to sticking to hard to a single tool or model—I prefer to focus on patterns between them. Building a CLD (as opposed to just viewing them) has some interesting positive effects. My goal in sharing then with blockchain community is those effects.

“HSMs do keep keys confidential, in a safe physical location which is tamper resistant.

“HSMs do not typically provide mechanisms for detection of key misuse & have no quorum auth…If an attacker compromises a system or application that has permissions to use keys…or if a rogue insider abuses such permissions, they can sign fraudulent cryptocurrency transactions…
“What all of this means, in practice, is that without robust usage controls in place, HSMs holding crypto-asset private keys, which only need to be used once to transfer ownership of potentially all funds in a wallet, have a vital vulnerability.”

You say “not my venue” — so what is your venue? W3C? I’d be glad to host a talk by you in the W3C Credentials CG, or find you other places in W3C to share your ideas. IETF? Which group? An academic conference?
Replying to @BenLaurie
We have discussed that key transparency (or more likely trillian) might also be able to offer a blockchain-less DID. But we’ve never been able to get someone with experience about it at one of our events or at W3C to work on a DID Method spec for it. I would support that work.
Replying to @BenLaurie
Much of #RebootingWebOfTrust and mostly at #W3C we also have not worked on identity—our biggest successes are for decentralized idenifIERS. These include ways to allow them to to have these 15 features: https://w3c-ccg.github.io/did-use-cases/#features
Replying to @BenLaurie
DIDs don’t have to be self-sovereign. The specification supports it, but there is nothing that says that a particular DID Method must be self-sovereign. A DID resolves to a data model where keys can be authenticated and supports some subset of actions: https://w3c-ccg.github.io/did-use-cases/#did-actions
Replying to @BenLaurie
The DID specification is going through a major revision right now based on lessons learned by multiple companies implementing it on multiple blockchains. Many of them plan to meet F2F at #RebootingWebOfTrust to resolve differences & present new draft soon: https://w3c-ccg.github.io/did-spec
Replying to @BenLaurie
Yet another reason if you want to support KT-type solutions for you to be at #RebootingWebOfTrust, or present your thoughts at the W3C Credentials CCG. I personally would love to see a blockchain-less DID method. The W3C Verifiable Claims WG is also meeting F2F the 2 days after.

I agree with @csuwildcat. As one of the inventors of DIDs it is premature to pick winners. Instead, we need to enable experimentation & cross-fertilization of results. We need to break out from POCs toward real world projects, but DID tech is too new for large scale deployment… https://twitter.com/csuwildcat/status/1099322877365563392

But once Blackphone had Google Play, our secure app store called “Silent Store” was cancelled. Eventually this made the Blackphone “just another Android phone” and perpetually a year behind other phones. Not being manufacturer made value-add hardware security solutions difficult.

We are working on social key recovery ideas at this week’s #RebootingWebOfTrust—some of those participating are using secure scuttlebutt (Dark Crystal) instead of Google. https://github.com/WebOfTrustInfo/rwot8-barcelona/blob/master/topics-and-advance-readings/security_shamirs.md I’m looking at whisper (aka Signal protocol) & nascent IETF MLS. HTC will be there.

The DID BTCR method is designed for censorship resistance. In fact, any old UTXO output (for instance some old dust) can be used as an initial DID. However, we are only as private as Bitcoin is, which is imperfect. Sovrin is experimenting with correlation resistance, we can’t.
Replying to @boscolochris, @windley, @Kyle_DH, @trbouma, @csuwildcat, @drummondreed and @SovrinID
We are hoping to get out at least a functioning POC of the BTCR method this week at #RebootingWebOfTrust. Some compromises are necessary to ship an MVP, details at: https://github.com/WebOfTrustInfo/rwot7-toronto/blob/master/final-documents/btcr_0_1.md

“The solution, to me anyway, seems almost too easy. Students should have two long classes each day for six to eight weeks. They should come to school in the morning and intensely study a single subject…When the term ends, they move on to another subject.” https://medium.com/s/story/the-insane-structure-of-high-school-762fea58fe62
When I was teaching for an MBA for Sustainable Systems program, I was part of team that designed a new first year. Instead 30 credit hours of typically 3 credit hour courses, it was a carefully designed sequence of a 9 credit hour course for three quarters, plus hour of coaching.
This meant, say for the 2nd quarter, Operations was taught same time as Marketing, which meant that an operations case study you used last week might be the starting point for a marketing case study this week. Everything was integrated. Hard on teachers though!
Replying to @killerstorm
I agree, but it is still possible to integrate some more. For instance math, physics & literature history have common threads if taught by eras.

Replying to @pamelarosiedee and @ACTobin
In the BTCR method you spend the UTXO output associated with your founding transaction without doing a key rotation.
Replying to @boscolochris, @pamelarosiedee and @ACTobin
No. But there is one foundational transaction that is on chain. Like a lightning node a BTCR DID is an encoding of blockheight, transaction in block & output index in that transaction. The output index must still have unspent funds associated with it. See: https://www.icloud.com/keynote/0Bcwqiyw6RGvMZgDyFt-prI_g#BTCR
Replying to @boscolochris, @pamelarosiedee and @ACTobin
Information about where to find information about individual claims issued by that DID are typically stored in IPFS objects which are widely distributed—there you can discover if it is revoked. Right they are CRLs, but there are hash tree based revocation list services coming.
