Question for twitter engineers: I’m puzzling with MTBF/R for SD & NFC cards. If the life expectancy of powered-off flash is 10 years, but you are sharing data using SSKR (our Shamir Secret Sharing technique) for 3 of 5 devices, you can expect 1 shard of those 5 to die in 2 years?

Tue Feb 08 00:26:36 +0000 2022

Replying to @adamshostack

Useful, but one challenge in puzzling this all out is that flash-based ssd drives, are also somewhat different powered-on and active vs powered-off. Flash is electrons in a volume of silicon, which will tunnel out if not refreshed. Denser flash, fewer electrons, more as % tunnel.

Tue Feb 08 01:21:45 +0000 2022

Thu Feb 10 17:38:12 +0000 2022

As a result, we’ve been able to put together an initial set of case studies highlighting how @FOUNDATIONdvcs Passport and @SparrowWallet ensure resilient and personal control of your digital assets. [3/12] https://github.com/BlockchainCommons/SmartCustody/blob/master/Docs/Case-Studies-Overview.md

Thu Feb 10 17:38:14 +0000 2022

The @SparrowWallet, though useful as a stand-alone software wallet, we’ve found is quite powerful if used as a transaction coordinator for multiple hardware wallets. Here’s our case study for how it supports the Gordian Principles. [5/12] https://github.com/BlockchainCommons/SmartCustody/blob/master/Docs/Case-Study-Sparrow.md

I believe the architecture of Ethereum wallets have a fundamental problem in that they do not have functional separation of keys, much less a no-key-reuse policy. This results in a number of confused deputy problems. It can be solved, but legacy architecture likely needs to die.

We have some ideas of how to maybe leverage a major revision of Wallet Connect 2.0 (3.0? some other name) that may solve some of these problems, but there has been insufficient will in the ecosystem to fund to support such a radical architecture so far.

Mon Feb 21 18:38:36 +0000 2022

Replying to @chelseakomlo

Absolutely agree! This is why our work on the Bitcoin side of the ecosystem is focused on Taproot Schnorr and toward Musig2 and Frost. However, there is still a place for slightly better than basic Shamir SS (such as 2-level Schnorr). Also, a VSS is a subpart part of Musig2.

Mon Feb 21 18:41:03 +0000 2022

Replying to @chelseakomlo

Again, true. This is why I help architect a design for key rotation in the W3C DID (Decentralized Identity) standards. (This feature is, unfortunately, is not mandatory in the spec). There are a number of approaches. Most are hard in the Ethereum/Metamask architecture though.

Mon Feb 21 18:43:30 +0000 2022

Replying to @chelseakomlo

Two issues. You are technically correct, but also incorrect. Musig2 has in its early round a VSS that is used to generate the final keys. You could do a one-party generation of this value, share, and those parties can sign things. Multiple Musig2 in a taproot tree can do quorum.

Mon Feb 21 18:46:25 +0000 2022

Replying to @chelseakomlo

I apologize, I am simplifying. The vast majority (of blockchain transactions (also by market cap) use ECDSA or 25519 with broken multisig. True threshold signatures typically use Schnorr (with secpk1 taproot or ristretto) but legacy bitcoin & Ethereum clones can’t use it.

Mon Feb 21 19:15:20 +0000 2022

Paste of markdown into Electric Drummer seems to half of it correctly, the outline. However, it doesn’t format the links.

Mon Feb 21 19:37:45 +0000 2022

Paste of markdown into the Zavala app just makes it a single entry. It fails both the break up the indents into outline or format the links.

Mon Feb 21 19:40:36 +0000 2022

Paste of markdown into Logseq comes closest to useful as it makes each line a separate outline entry and does the link formatting, but looses the hierarchy.

Mon Feb 21 19:45:19 +0000 2022

It turns out pasting markdown into Logseq is more useful than I thought, but it doesn’t know the difference between a body paragraph and a L1 indent, and creates a redundant line. See GitHub issue: https://github.com/logseq/logseq/issues/4333

For one, Blockchain Commons is about more than just software & hardware engineering. We’re also looking to nurture pre-law students, technical writers, library science, and other people who might help us advocate for secure & compassionate digital infrastructure. [3/11]

We look forward to working with these aspiring students. To have them join with us to create an open & interoperable, secure & compassionate digital infrastructure. To support human dignity and enable people to control their own digital destiny. [10/11] https://www.blockchaincommons.com/vision.html

The forty hours of work (plus office hours & educational opportunities) will occur this summer from May 23, to August 15, 2022. Since it’s a virtual program, you can of course be anywhere in the world. One of the best parts is collaborating internationally! [9/11]

To apply for this year’s internships, just email us a CV with some additional info as described in this year’s call for interns. The deadline is April 22nd. [8/11] https://github.com/BlockchainCommons/Community/discussions/74

One possible hidden tragedy in this Russian invasion is that they don’t need to capture the Dutch civil archives like the Nazis did. New civil hackers like 🇳🇱 Arondias who burned archives or 🇫🇷 Carmille who punched holes in all the cards can’t as Russians already have the data!

I’m saying they don’t need to. We already know that Russian supported hackers have been scraping Facebook and other social networks, and have targeted Ukrainian services for at least a half-decade. They likely already have the data. And we gave it away.

My big security concern lately is the MetaMask-style & Wallet Connect 1 & 2 binding to a single key used for everything from login auth, displaying balances & NFTs, and asset transfers. Severe “confused deputy” problems. If this EIP just fixes key separation & rotation, then 👍.

Replying to @chrismessina, @kimdhamilton, @wycdd, @Obstropolos, @SpruceID, @openid, @bluesky, @willnorris, @selfissued and @justin__richer

The Confused Deputy problem is when an entity is inappropriately authorized to do something minor (say login) but that auth reused, tricked or coerced to do something major (say transfer an asset) that they did not intend. Very common attack vector right now with ETH & friends.

Replying to @chrismessina, @kimdhamilton, @wycdd, @Obstropolos, @SpruceID, @openid, @bluesky, @willnorris, @selfissued and @justin__richer

The best way to avoid this is to use different keys for different purposes. Another useful approach is a “Key Rotation” architecture, as supported by some DIDs, which allows you to keep the identifier but change the keys it uses (and deprecate the old ones).

Replying to @chrismessina, @kimdhamilton, @wycdd, @Obstropolos, @SpruceID, @openid, @bluesky, @willnorris, @selfissued and @justin__richer

I looked over EIP-4361 and it still appears to be single-key, single account focused, and also does not add privacy nor is rotatable. I really can’t recommend it even though it has improvements over existing wallet login methods. I believe we can and should do much better.

We (@BlockchainComns) are currently investigating how to apply the Gordian Principles for #SmartCustody for the Eth & friends wallet ecosystem. Currently seeing if there is interest by our Patrons to fund. One preliminary DRAFT on the issues is at https://hackmd.io/rEcjDqAlS3OS1bwojFiEnA

This isn’t a problem with Ethereum blockchain itself, but a real problem with how the architecture of the ETH wallet ecosystem evolved. I’m not confident it is incrementally fixable. Maybe we can, but sometimes you just need a fundamental reboot and start over.

Yes, that’s the flaw of a radically more secure design — we likely would have to abandon legacy wallets (and some common contracts!). Thus we don’t want to dive in without more evidence from our Patrons & partners that there is financial support for the long haul to do it right.

Replying to @wycdd, @chrismessina, @kimdhamilton, @Obstropolos, @SpruceID, @openid, @bluesky, @willnorris, @selfissued, @justin__richer and @BlockchainComns

We might start instead by doing responsible key management wallet architectures with DAO treasury wallets, or some other subset of well-funded groups of users first, rather than replace wallets for individual investors.

I’m beginning to get signals that the market may be fed up with current architecture. But I’m not committing without more financial patrons committed to working together on it.
