It can be argued that the founding of the United States was an early decentralization effort. We should return to having decentralization be a political ideal. 👍 @avichal https://twitter.com/avichal/status/1142869865222377473

True, but if it wasn’t decentralization it would be some other tool that selfish people leverage. The question is if the broad resilience that decentralization supports is worth that we also have to put some effort into preventing misuse.

The challenge is that multisig solutions are currently difficult and not very mature. In the meantime we are working on standardizing Shamir Secret Sharing SLIP-0039 with will be well-reviewed reference code (currently Python & C). Seeking supporters & patrons to fund review.

I suggest you look at SLIP-0039 which is a specification for Shamir Secret Sharing of BIP-39 recovery mnemonics. It includes unaudited python code. We also have some early C code implementing it that @htcexodus & @BlockchainComns is seeking review for. https://github.com/satoshilabs/slips/blob/master/slip-0039.md

Both. Even once Schnorr is soft-forked into Bitcoin (not trivial) the key establishment process is not well understood from UX perspective. I’m confident that it will be solved, but in the meantime a better Shamir at the hardware wallet level will address some immediate needs.

US Congress in current FY2020 Omnibus bill added to allow HHS to lend assistance to the private sector for the development of a unique patient identifier (UPI), previously barred since 1999. A single patent ID is a VERY bad idea for privacy reasons!

I was quoted by @mike_orcutt in @techreview “On the whole, though the technology of decentralized identity has advanced to the point of several serious pilot tests, it’s not anywhere near ready for adoption by billions of people around the world…” https://www.technologyreview.com/s/613877/how-facebooks-new-blockchain-might-revolutionize-our-digital-identities/

It requires more than mentoring and internships. It requires externships (what master chefs call ‘staging’) of journeymen (& even among masters!) to share the knowledge. All of these I’m puzzling through how @BlockchainComns can facilitate.

Doing it well is hard. We (@BlockchainComns) tried to condense down peer reviewed checklist of best practices for protecting your master keys for digital assets, but it still isn’t easy enough. Then modifying it for different risk models is even harder. https://github.com/BlockchainCommons/SmartCustodyWhitePapers/blob/master/%23SmartCustody-_Simple_Self-Custody_Cold_Storage_Scenario.md

There are a number redundancies discussed in the procedure (see final state image) and an optional “Redundant Metal Devices” process where you split the words such that you need 2 of 3 metal tiles to recover, giving you some resilience at acceptable loss of security if 1 is lost.
