From starting with P2SH 10 years ago, to PSBT's, HWI, offline signing, descriptor wallets, taproot, and GUI support, we have come a long way! Click here to view selected posts on the Multisig Project from the main page.
Qubes is an operating system based on the principle of security by compartmentalization. Using the bare-metal hypervisor Xen, it reduces the trusted code base, isolates network cards, USB controllers, the GUI, and other domains with predefined purposes and levels of trust. However, it is currently only operable on the x86 instruction set. Power ISA is the only open source ISA that has actual open source implementations (SBC's) on the market. This makes it significantly more secure. Click here to view selected posts on the Qubes Project from the main page.
Yeti is a minimal Python script and UI layer run on top of Bitcoin Core that enables easy, secure, air gapped, offline HD multisig, all with minimal software dependencies. Arctica is an evolved version of Yeti that added a Duress Protocol, solved Multisig's privacy issue with backups, and has a Tripwire Protocol to alert you if any single signer is taken by an Adversary.
