Our 2nd FROST Implementors Roundtable will be on Sept 18th for cryptographers, protocol and library devs. Another meeting on Dec 4th will focus on wallet developers integrating these tools. If you would like to present at either meeting, let me know. https://developer.blockchaincommons.com/frost

Details, video and transcripts from our 1st FROST Implementor’s meeting is at https://developer.blockchaincommons.com/frost/meeting1/, and our 1st FROST wallet devs meeting at https://developer.blockchaincommons.com/frost/developers1/. Many thanks to the Human Rights Foundation (@HRF) for sponsoring these events.
Replying to @ChristopherA
So far we have presenter’s confirmed more from the Bitcoin side of FROST, but we hope to have other library implementors present, in particular from @ZcashFoundation’s FROST implementation to update us on their work and progress with IETF and NIST standards.

Several other wallet devs have considered it, but were put off by SLIP-39. Hopefully there will now be more momentum.

As hardware wallets proliferate, as multisigs come into increased use, and as digital currencies become more commonplace, you’ll likely need more than one seed for your assets. BIP-85 is one way to manage that. [2/7]
As a reminder, the special @BlockchainComns BIP-85 presentation for wallet developers is coming up this Wednesday, the 7th. [1/7] https://github.com/BlockchainCommons/Gordian-Developer-Community/blob/master/meetings/bip85-meeting.md
Replying to @ChristopherA
Ensuring users don’t lose their digital assets is one of the most challenging elements of self-sovereign asset control. It’s been one of the priorities at @BlockchainComns from the start. [5/7] https://www.smartcustody.com/
Replying to @ChristopherA
We’ll also talk about other ways to improve seed resilience at our meeting: Sharded Secret Key Reconstruction (SSKR), Collaborative Seed Recovery (CSR), Gordian Depository, etc. The link (below) has the URL for the meeting and calendar invite. [4/7] https://github.com/BlockchainCommons/Gordian-Developer-Community/blob/master/meetings/bip85-meeting.md
Replying to @ChristopherA
BIP-85 specifies how to generate children seed from a master seed, so you can have “One Seed to rule them all”. [3/7] https://github.com/bitcoin/bips/blob/master/bip-0085.mediawiki

I’ve been trying to get the Zcash wallet dev community to be involved in Gordian Wallet standards, including UR PSBTs, SSKR and other seed resilience best practices, etc. Any endorsement of these to encourage them is appreciated.
I’ve been talking about wallet key exfiltration attacks since first heard about them from @pwuille in 2018. There just hasn’t been demand because it required wallets to keep state. This is exactly what our Gordian Sealed Transport Protocol (GSTP) addresses with its Encapsulated… https://twitter.com/ChristopherA/status/1651308417187999745

Basically, with GSTP and ESC, a wallet transaction coordinator can contribute toward a nonce and send it to the hardware wallet, along with encrypted state. The signer incorporates that nonce, and returns it along with the encrypted continuation, which the coordinator can then…

Blockchain Commons in our #SmartCustody efforts has done a lot to support the resilience of seeds , so they won’t be lost, as we think that’s the number one adversary for most self-sovereign digital-asset holders. But there are new approaches emerging. [2/9]
This month’s Gordian Developer Meeting (first Wednesday) hosted by @BlockchainComns was all about seed resilience. It’s the vitally important “Level 0” for cryptographic security. We’ve got a video of the complete discussion [1/9]. https://www.youtube.com/watch?v=e6Ag1X2oC1Y
Replying to @ChristopherA
Blockchain Commons hasn’t focused on BIP-85 much to date, but it’s starting to gain momentum, with implementations from people like @FOUNDATIONdvcs and @COLDCARDwallet. We think it deserves more attention in the future! [4/9]
Replying to @ChristopherA
One is BIP-85, a seed-of-seeds methodology that lets you use one seed to generate seeds for all of your devices. @akarve, a BIP-85 Champion, gave a presentation on the topic. [3/9] https://www.youtube.com/watch?v=4W4kmV-oHrA

Why use Gordian Envelope? The fundamental reason is hashed elision. It empowers Data Minimization, allowing any holder of data to redact data that should be private, while still maintaining validation & integrity. The video explains more! [2/11]
Gordian Envelope is a Smart Document system that supports secure data storage and holder-based elision. We’ve created a new “Understanding Gordian Envelope” video that introduces the technology. [1/11] https://www.youtube.com/watch?v=-vcLCFKQvik&list=PLCkrqxOY1Fbqpl8FLvG2uoA2xAMoR0FtS

Gordian Envelope Extensions allow you to do more! Signing, encryption, compression, remote functions, it’s all here. But you only pay for what you use! Envelope can be as simple or complex as you need. [5/11]]

Replying to @ChristopherA
Part one of the video focuses on the Envelope metaphor and key concepts such as cryptographic hashes, elision and redaction, determinism, and dCBOR. It also talks about how data is represented in an Envelope. [3/11] https://www.youtube.com/watch?v=-vcLCFKQvik&list=PLCkrqxOY1Fbqpl8FLvG2uoA2xAMoR0FtS

If you need communication that’s secure, transport-agnostic, and distributed, that’s GSTP. Whether you communicate via the internet, bluetooth, NFCs, or QRs, GSTP supports the security of your data. [7/11]

Many of Gordian Envelope’s extensions combine to support Gordian Sealed Transaction Protocol, which was also the subject of a recent video. [6/11] https://www.youtube.com/watch?v=QnH14LkJOnI&list=PLCkrqxOY1Fbqpl8FLvG2uoA2xAMoR0FtS
