Too many single points of failure (I think I count 5). Resilience is as important as security. All could be addressed, but likely not while keeping compatibility with old system. We designed a 2 of 3 for another company where we looked at 64 different points of failure.

Depends on your definition of L1. I’d say release of Chia approaches viable end of L1 tokens, but I suspect futures could include splitting L1 into L0 & L1, L1s optimized for L2/L3, and wildcards like no-token L1s, homomorphic or quantum L1s & lightspeed bound (Mars? Oort?) L1s.

Apple promised us almost a year ago the option to disable signing certificate checks with Apple’s OCSP servers, a privacy risk when you install apps. Nothing so far in Monterey. Should have been fixed by now. https://eclecticlight.co/2021/11/08/will-apple-honour-its-promises-on-ocsp-certificate-checks/ @howardnoakley
Interesting! It looks like you can soon sign git commits with ssh too. Also pleased they have signature name spaces (similar to proof purpose in DIDs) – lack of this is a common flaw in a number other signature schemes. 🕵🏻♂️ https://twitter.com/__agwa/status/1459194182459961346
Also important to me is ssh is pre-installed in most systems today, so you don’t have to install anything to bootstrap file signing. This has always been a catch-22 when I’ve looked into securing a new system against install hijacking (e.g. curl bash) & supply-chain attacks.
One of the concerns might be that GitHub is suggested for key distribution, but you instead use did:onion method (https://blockchaincommons.github.io/did-method-onion/ & implemented at
https://github.com/BlockchainCommons/torgap-demo).) /cc @__agwa
We have a solution for a “universal donor” 25519 key that can be transformed into both minisign & tor keys (https://github.com/BlockchainCommons/torgap-sig & https://github.com/BlockchainCommons/torgap-sig-cli-rust).) I’ll have to see if there are any issues with leveraging ssh keys as well.

I’ve been looking forward to the opportunities from Bitcoin Schnorr since it was first demonstrated by the Elements team at @Blockstream 6 years ago! You could say I’ve been waiting for it since I tried to get a patent license for it in 1999 when I was CTO at Certicom! 👏🙏 https://twitter.com/pwuille/status/1459778730369368067
Great thread here hinting at some futures for Bitcoin Lightning now that the Taproot/Schnorr soft fork has activated. If you hadn’t noticed, the @BlockchainComns logo are borromean rings, chosen as I’ve been intrigued by ring signatures. https://twitter.com/TheBlueMatt/status/1460081817609027595
This is definitely true. 30 years ago with SSL & choice of CAs we were trying to avoid the tyranny of a Microsoft “one ring rule them all”. Progress, only to find over time consolidation of CAs & power of Google & Facebook to re-centralize. Today’s tech too can be re-centralized. https://twitter.com/ldodds/status/1458562522919936001
I highly recommend the DID Method Rubric to see the difficulties in evaluating decentralization. My own hypothesis is that we will discover that, like Arrow’s Impossibility Theorem is for voting, that perfect decentralization is not possible. https://www.w3.org/TR/did-rubric/

I see a lot of FUD about token-based identity systems. I agree that we still must be careful, but first you have to understand what people mean by token-based identity.

I’m not sure that this ‘simple’ explanation cuts it. The reality is these NFTs do not (or rarely) have any rights other than to transfer the token. What they are is a way to signal status & membership. In fact, many have exclusive chat channels only available to holders.
Replying to @trbouma
I’m big on smart contracts to support rights (or ocaps). However, I think we do a disservice to not express that the main value of NFTs is to signal status (like designer clothes) or virtue with or membership in a group (I get to show that I’m a member + exclusive access to chat)

This is excellent work exploring the complex nature of various cryptocurrency key scenarios.

— what would it take to get your tool up to 5 keys, so I can look through various 3 of 5 scenarios (which are quite popular)? I’m particularly also interested in 4 of 9 (or in my case, 2 of 3 of three 2 of 3s using SSKR or a bitcoin taproot/schnoor contract).
Here is an early draft of some work I’m doing to dive deeper into multisig scenarios: “Designing Multisig for Independence & Resilience” https://github.com/BlockchainCommons/SmartCustody/blob/master/Docs/Multisig.md
Another on “Designing SSKR Share Scenarios” which supported by our SSKR libraries and reference apps: https://github.com/BlockchainCommons/SmartCustody/blob/master/Docs/SSKR-Sharing.md
