At Blockchain Commons @BlockchainComns and at the last two #RebootingWebOfTrust we’ve been working on better standards for social key recovery, one result of which is the Shamir based slip39. But a side consequence is revisiting BIP39. We hope to have compatible alternative soon.

The article is interesting. Storage leads to databases which leads to abuse. By storing the info on a card held by the patient the patient controls its use and access to services.

Not looked at this project, but I’ve been suggesting for years that some older tech, like Chaumian Blinding (used by DigiCash back in 90s), is worthy of reinvestigation as many of their centrality problems can now be solved. Given new BIP-Schnoor code is emerging, worth a look. https://twitter.com/NickSzabo4/status/1187089734910136326
Tails 4.0 is out, which is important for Bitcoin power users because it now supports a current version of the @ElectrumWallet when using Tor. I have an interesting #SmartCustody idea for a multisig PSBT scenario using multiple #TailsOS USB keys. https://tails.boum.org/news/version_4.0/index.en.html
Replying to @Justin52_tw and @ElectrumWallet
There are a number of #SmartCustody cold storage problems where fiduciary responsibility requires separation of duties. With Tails, each manager can generate generate their own keys (save to offline titanium) and then create a multisig address. When you close Tails all is wiped.
Replying to @Justin52_tw and @ElectrumWallet
Later, they can use their offline key backups to sign a PSBT to recover their funds from cold storage. Advantage of Tails is it is a well known, almost deterministic-built, all in RAM OS that is hard to remote compromise. If @ElectrumWallet supported SLIP39 even better.
Replying to @liber_liver and @ElectrumWallet
That is a legitimate question, but one that can be addressed in the recovery process checklist.
Replying to @Justin52_tw and @ElectrumWallet
Tails is ephermal by default. No data is saved. All keys are are saved offline.
Replying to @Justin52_tw and @ElectrumWallet
By default Tails does not have any persistence. It doesn’t, by default, store anything on the USB. Though you can store persistent data in an optional encrypted volume, you don’t need to do so in my process checklist as you enter your offline 12/24 words, erased from RAM after.

Some of the code we used to create our dictionaries are at at https://github.com/ChristopherA/password_poem - some of this data was used to inform word selection of SLIP39. Hope to return to this side project soon.
Replying to @Justin52_tw and @ElectrumWallet
Yes. Of if Electrum eventually supports SLIP39 then write down al least 60 and restore 40. But there are some advantages to this depending on your attack scenario.

As far as argument, devs are moving off of GitHub because Microsoft is proving that they don’t understand the underpinnings of why people contribute to open source. Apple has shown that at trying to stick to your principles can gain you good will. It should have gone to court.

Decentralization isn’t a spectrum (i.e. a line) but a continuum of multidimensional space. There are at least three axis, maybe 4 or more, and the area is not convex but concave, such that there are gaps where increasing in one dimension decreases another.
Replying to @anguschampion
There also is a hole in the center of the continuum, as there can be no perfect decentralization. Like Arrow’s Theoem for voting system design, as some criteria of decentralization are mutually exclusive of others.
