Hi
I thought this transcript might be of interest to the mailing list.

Jesse Posner joined the online Sydney Socratic [1] last month to discuss his
work on FROST. There is a video [2] too. As Jesse states [3] "With the
introduction of Taproot, we can begin to bridge this divide between a "hot" and
"cold" key by leveraging distributed key generation and threshold signing."
During the Socratic he discussed how with FROST you can simulate a threshold
signature arrangement (k-of-n, k<n or indeed n-of-n) with only one signature
going onchain when making a transaction. There are lots of upsides, you can
swap participants in and out without needing an onchain transaction and even
change the arrangement from say a 3-of-5 to a 4-of-5 without needing an onchain
transaction. There are challenges too of course and it was discussed how the
various participants might swap nonces and keep track of which nonce they
should be using when signing, how hardware wallets might support FROST and to
what extent accountability can be achieved if malicious parties are included in
the threshold arrangement.
Thanks to Lloyd Fournier for organizing it and thanks to Adam Jonas for
maintaining the btctranscripts.com site. The Sydney Socratic is online, open to
all and Lloyd has a number of ideas for future topics.
