Though we at @BlockchainComns appreciate the free hosting of open source projects by GitHub, the centralization when they were acquired by Microsoft is a bit unnerving. At least the underlying git software is supports ‘distributed’. I’m intrigued by @radicle which moves git… https://twitter.com/radicle/status/1772659708978991605
In two hours will be having our developer-oriented discussion about FROST. It is useful not only for tap-root Bitcoin, but DKG (Distributed Key Generation) is an important future for all digital assets, as you don’t have to rely on the security of any single CPU. https://twitter.com/ChristopherA/status/1774680107380048144
Wednesday’s well-attended Gordian Developers meeting at @BlockchainComns focused on FROST, with a special presentation introducing and updating the technology by @jesseposner. If you missed it, we have a full video [1/9] https://www.youtube.com/watch?v=uCM8dDql6oo
Replying to @ChristopherA
One of the most exciting elements is its support for Distributed Key Generation (DKG). With FROST’s Schnorr signatures, individuals sign with their shares, which are then aggregated. The whole key never exists! [3/9] (image from @cryptohopper)
Replying to @ChristopherA
FROST is Flexible Round-Optimized Schnorr Threshold Signatures, which uses Schnorr signatures (now integrated into Bitcoin with Taproot) to allow a whole new type of multisig. [2/9] https://developer.blockchaincommons.com/frost/
Replying to @ChristopherA
Lose a share? Want to update shares? Need to increase or decrease membership? Want to adjust your threshold? It’s all possible off-chain WITHOUT moving funds! Take a look at the video for more. [5/9] https://www.youtube.com/watch?v=uCM8dDql6oo
Replying to @ChristopherA
Jesse also talked about some of the exciting experimental work going on with FROST, including the ability to REFRESH or REPAIR shares, ENROLL or DISENROLL participants, or change the THRESHOLD. [4/9]

👍 With basic SSKR you can have a huge amount of flexibility of options, not just 3 of 5, but interesting choices like two of three 2 of 3s (a kind of 4 of 9 preventing collusion). In newer Envelope SSKR, you can also backup important metadata. https://twitter.com/BitcoinLixin/status/1778603239455555849
Today @BlockchainComns posted its Q1 report. It covers updates to our digital asset wallet specifications, reference code, as well as new research into multisig, FROST, constrained devices and data provenance. Become a sponsor to support our work! [1/10] https://twitter.com/BlockchainComns/status/1780638280876544208

Blockchain Commons is also pushing hard on the topic hashed data elision (aka provable redaction) in general, which resulted in a new IETF problem statement about why it’s important for privacy and human rights. [3/10] https://datatracker.ietf.org/doc/draft-appelcline-hashed-elision/
Replying to @ChristopherA
We made progress in the IETF with our dCBOR specification, which is deterministic CBOR. It’s critical to be able offer hashed data elision in formats such as Gordian Envelope. [2/10] https://datatracker.ietf.org/doc/draft-mcnally-deterministic-cbor/
Replying to @ChristopherA
The quarterly report also includes details on other recent work from @BlockchainComns, including research on constrained devices, digital provenance, and the release of Gordian Seed Tool 1.6 on iOS/mac and Gordian Server 1.1 for macOS. [8/10] https://www.blockchaincommons.com/quarterlies/Q1-2024/
Replying to @ChristopherA
Why is GSTP request/response important? Because it makes complex procedures like multisig creation actually usable! [7/10] https://github.com/BlockchainCommons/SmartCustody/blob/master/Docs/Scenario-Multisig-RR.md
Replying to @ChristopherA
The Gordian Sealed Transport Protocol (GSTP) Implementation Guide similarly discusses how to implement requests and responses using Gordian Envelopes, to allow for easy-to-use secure communication between airgapped devices.

This new proposal (BIP 77 PR) simplifies PayJoin’s usage by not requiring the receiver to have a public server to help transmit the negotiations, taking advantage of the tooling currently used by our animated QR specifications for Airgap PSBT. [3/8] https://github.com/bitcoin/bips/pull/1483
Replying to @ChristopherA
The original PayJoin (BIP 78) was a 2019 Bitcoin proposal that better preserved privacy in Bitcoin transactions and gave a receiver the opportunity to consolidate their own UTXOs without new fees (and without mixing!). [2/8] https://github.com/bitcoin/bips/blob/master/bip-0078.mediawiki
Our upcoming May 1st Gordian Developer Meeting will include a feature presentation by Dan Gould (@bitgould) on BIP77 Serverless PayJoin v2. [1/8] https://github.com/BlockchainCommons/Gordian-Developer-Community/blob/master/meetings/2024/05-01/payjoin-meeting.md

We started RWOT in San Francisco in 2016 to celebrate the 25th anniversary of PGP. Since the beginning it’s been a event like no other, where experts gather together and produce papers or other collaborative artifacts, in just 4 days. [2/10] https://www.weboftrust.info/about/#the-workshops
After hosting @RWOTEvents a few years abroad, I am thrilled to have Rebooting the Web of Trust, our collaborative design workshop on decentralized identity, back to its original home in California, with #RWOT13 occurring October 7-11, 2024 in Ventura, California [1/10] https://twitter.com/RWOTEvents/status/1781161198085714230

One of the biggest fallacies about the Bitcoin network is the claim that it’s anonymous. It isn’t. But @bitgould is working on improving privacy with PayJoin v2. Join us for their presentation on the topic at @BlockchainComns on May 1 at 10am PT. [1/12] https://github.com/BlockchainCommons/Gordian-Developer-Community/blob/master/meetings/2024/05-01/payjoin-meeting.md

Replying to @ChristopherA
PayJoin offers more of a veil by allowing both transactors to contribute coins, but without the more complicated mixing of a system like CoinJoin. It can save fees too by allowing the recipient to consolidate coins! [3/12]
Replying to @ChristopherA
A problem with privacy on Bitcoin is that transactions can be forensically analyzed. One transaction going to two UTXOs? That’s a payment from the first person to the second, plus some change. [2/12]
Replying to @ChristopherA
Our major Envelope presentation will look at how its Request & Response system can be used to automate hard-to-manage tasks such as creating multi-device multisigs. [7/12] https://github.com/BlockchainCommons/SmartCustody/blob/master/Docs/Scenario-Multisig-RR.md

We (@BlockchainComns) used my legacy IPv4 “swamp” C space to help host a Tor Exit node. If the four you received are “swamp” then they are each individually routeable. Maybe use one to consider hosting another? https://metrics.torproject.org/rs.html#details/644074F47257F9A906F9AA5C6B8926C1540A1DA8
