Blockchain Commons @BlockchainComns has long recognized #multisig as the future of how we handle responsible key management for cryptocurrencies and digital assets, as well as an important future for digital identity and authorization. [1/13]

But multisig is just a tool. Our goal is to increase security (so that your funds aren't stolen) and safety (so that you don't lose your keys), while simultaneously ensuring the reliability and accessibility of your funds. In short: #SmartCustody. [2/13] https://www.smartcustody.com/

We're currently in the process of writing a design guide for multisig. It's a step-by-step process for constructing different kinds of multisig transactions that specifically addresses adversaries like Network Attacks, Theft, Social Engineering, and Key Fragility. [3/13]

Are there other adversaries that you think aren't being considered by traditional single-signature accounts? Or even by newer multisignature accounts? [4/13]

Design Patterns are the cornerstone of our approach to multisigs. These are standard techniques like "Partition of Keys", "Separation of Interests", "Backup of Keys", and "Time Locking of Funds", each of which addresses specific adversaries. [5/13]

We also think that adversaries can be defeated by ensuring that each key in a multisig comes with a role: a specific way in which it's intended to be used. We've identified Proposer, Authorizer, Corroborator, Emergency Responder, Auditor, Backup, Watcher, and Watchtower. [6/13]

Are there Design Patterns you've found effective for creating multisigs? Are there roles that represent other ways in which keys should be used? Let us know your answers! [7/13]

These topics are particularly important for self-sovereign solutions, where a good design can mean the difference between autonomously protecting your funds ... and losing them all. [8/13]

We are not only about the theoretical design — we're also working on practical considerations, such as how to establish multisig policies & how to safe gather together public keys multisigs. We believe this is an area that deserves more attention. [10/13]

At Blockchain Commons we're working on what we think are the important foundations for safety & reliability of blockchain technology, including creating good architectures and supporting vendor independence. [11/13]

However, Blockchain Commons is not endowed, nor does it have any notable supply of bitcoins. We're running month to month solely with support from patrons. [12/13]

Today, as the first of March, is our budget day. The more support we have, the more we can do. The less we have, the less we can do. Support us TODAY to increase our work, become one of our GitHub patrons. [13/13] https://github.com/sponsors/BlockchainCommons
