I’m still thinking about this a year later. I’m not sure oracle is the right word — I guess what I’m seeking is closer to the concept of a Fair Witness (from Heinlein’s SiaSL), someone specifically trained to offer evidence based on non-subjective observations, without deduction. https://twitter.com/ChristopherA/status/1080723865972535296

There are still issues of privacy loss when revealing of master key fingerprints & xpub reuse that I’d like to see addressed, but as these are not a critical privacy bugs they have not been a priority. I’ve written up some thoughts at: https://github.com/BlockchainCommons/Airgapped-Wallet-Community/discussions/53

Mon Jan 03 08:53:56 +0000 2022

Our latest release also allows you to sign PSBTs presented to Gordian Seed Tool, supporting its use with airgapped wallets like @SparrowWallet as a transaction coordinator. [4/5] https://github.com/BlockchainCommons/GordianSeedTool-iOS/blob/master/Docs/Integration.md#using-sparrow-as-a-transaction-coordinator

Mon Jan 03 08:59:23 +0000 2022

Gordian Seed Tool helps you do so, by allowing to main personal control of your own seeds and thus your own digital assets. [3/5]

Mon Jan 03 08:59:23 +0000 2022

Bitcoin was founded as a way to avoid the follies of centralized banking infrastructure, as logged in its Genesis Block: “The Times 03/Jan/2009 Chancellor on brink of second bailout for banks.” [2/5]

Mon Jan 03 08:59:23 +0000 2022

It’s Bitcoin’s lucky 13th birthday. To celebrate we’re putting Gordian Seed Tool for iOS & Mac on sale for 99 cents for the next few days [1/5]. https://apps.apple.com/us/app/gordian-seed-tool/id1545088229

Related there is now an airgapped wallet format for output descriptors that is beginning to be implemented by multisig wallets. Advantage is you can request the kind of you keys you need with QR. https://github.com/BlockchainCommons/Research/blob/master/papers/bcr-2020-010-output-desc.md

Mon Jan 03 16:45:47 +0000 2022

The newest version of Gordian Seed Tool, 1.3, is out, and you can now run it on both your Mac or your iOS device. It is also on sale for Bitcoin’s 13th anniversary! [1/9] https://twitter.com/BlockchainComns/status/1478063575428001793

Mon Jan 03 18:14:47 +0000 2022

Gordian Seed Tool is built on the Gordian Principle of resilience. It shows you how to keep your crypto-seeds safe: by storing them on a closely held device. [3/9] https://github.com/BlockchainCommons/Gordian#gordian-principles

Mon Jan 03 18:14:49 +0000 2022

One of the most exciting new features is the ability to sign PSBTs using your stored seeds. [2/9]

Mon Jan 03 18:14:49 +0000 2022

We recently documented an example of how to do so with @SparrowWallet. [5/9] https://github.com/BlockchainCommons/GordianSeedTool-iOS/blob/master/Docs/Integration.md#using-sparrow-as-a-transaction-coordinator

Mon Jan 03 18:14:50 +0000 2022

But usability is also very important: you have to be able to use your seeds! That’s what Gordian Seed Tool 1.3 supports: PSBT signing with the seed never leaving your device. [4/9]

Mon Jan 03 18:14:50 +0000 2022

You let Sparrow act as a Transaction Coordinator by sending it a Cosigner Public Key. Then, when Sparrow wants to produce a transaction, it creates a PSBT that is sent as a QR Code to Seed Tool for signing [5/9].

Mon Jan 03 18:14:51 +0000 2022

There are two ways to conduct this exchange. Sparrow currently uses the older method of exchanging crypto-psbt URs, while we expect newer releases will use our request/response methodology. [7/9] https://github.com/BlockchainCommons/Research/blob/master/papers/bcr-2021-001-request.md

Mon Jan 03 18:14:52 +0000 2022

Seed Tool displays the details of the PSBT, asks for your permission, signs, and then sends it back in the same way. [6/9]

Mon Jan 03 18:14:52 +0000 2022

The monthly patronage from our @BlockchainComns Sponsors (via GitHub) makes this kind of app possible, as well as our broader efforts for wallet interoperability in the Bitcoin ecosystem with specifications & reference code. Support us today! [9/9] https://github.com/sponsors/BlockchainCommons

Wed Jan 05 19:00:01 +0000 2022

Our most important new spec for the year was the request/response design pattern for our Uniform Resources (URs). [4/11] https://github.com/BlockchainCommons/Research/blob/master/papers/bcr-2021-001-request.md

Wed Jan 05 19:00:02 +0000 2022

For me when I was CTO of Certicom working on microcurrencies circa 2001, the biggest challenge was that Schnorr was best for blinding, and the patent holder wanted 5% of upstream gross revenues. Since they were non-practicing patent holders, progress was impossible.

Kyle is a software business lawyer who writes very human readable contracts, but also writes code, uses git, and understands our business. He has written this web app to help you choose a license contract, and asks (“honor system”) for you to pay $100 if you use it. Take a look! https://t.co/n1JreFGaRh

This is an update to the existing state identity theft law, which protects residents of Wyoming. The biggest difference is that under the new digital identity legal definition, this crime isn’t only about theft or property loss, but also for violation of authority.

There has been some discussion of a new e-residency law, which besides being able to register corporations (like Estonian e-residency) might also allow non-residents to be able to register for various digital protections under Wyoming laws, but it not on agenda for 2022 session.

I don’t believe that properly constructed scriptless scripts suffer from the same problems that Schnorr blind signatures do (when Schnorr is properly constructed with FROST & Musig 2). But @AnnaLysyanskaya may know otherwise.

I’m not a silicon expert myself, so I’m seeking more sources for my statement above, but especially given the commodity nature of SD cards today, and this report, it doesn’t look good: https://www.ni.com/en-us/support/documentation/supplemental/12/understanding-life-expectancy-of-flash-storage.html

Thu Jan 27 22:41:03 +0000 2022

In our #SmartCustody research regarding the longevity of cryptographic keys & avoiding bitrot, and after some discussion with hardware & silicon experts, we don’t recommend storing keys & encrypted data on SD cards. The exact MTBT is not clear, but ~2-3 years may be typical.

Thu Jan 27 22:41:03 +0000 2022

Part of the problem in getting a complete understanding of this issue is that most discussion about NAND Flash-based storage is for active devices under power. There is very little analysis of SD longevity without active usage and long periods with no power.

Thu Jan 27 23:50:41 +0000 2022

Another problem is that the reports about this are not free. For instance, it is reported that the JEDEC standard for SSDs is at 30°C and power off that data can be retained for 52 weeks. But I don’ have access to the source document for actual details: https://www.jedec.org/document_search?search_api_views_fulltext=ssd

Thu Jan 27 23:58:35 +0000 2022

A final challenge in understanding the problems is all of these reports are about high-performance SSDs, not cheap, commodity price-driven SD cards. Thus my best guess is 2-3 years may be reasonably safe, but 8-10 years is quite likely dangerous.

Most of Blockchain Commons efforts to date have been on the Bitcoin side of the community, but we are in process of building consensus to bring some of our #SmartCustody work to the EVM side. The core problem is architectural & there is little funding for wallet infrastructure.

Dad salesman with small companies, mom a grade-school teacher. Both became professional sailboat captains. One grandpa ran a drive-in restaurant, the other was a weatherman for the AF & became a high-school teacher. I do consider this privileged — we had no hardships.
