Seeds + hardware signers are a very powerful combination that give full control and transparency to the user.
Working hard on http://Bitcoin-Safe.org to make hardware signers (also in Multisig) easier to use

Compact Block Filters are a fast and private way to fetch blockchain data directly from Bitcoin Core nodes and Bitcoin-Safe.org will use it asap.

Interesting. It includes a chip reader too and is really cheap.
I think this would be a reasonable choice for the recovery signer in a 2 of 3 multisig, as long as the chip card is pin protected.

Not currently, since nfc readers for desktop are rare.

How can I use nostr for a community channel for @nprofile…luuf?
A kind of reddit/discord/telegram style chat where users can discuss topics and get help.
Requirement:
- very easy to create a new nsec to get started
- web browser is sufficient
- some moderation tools by an admin (banning npubs,...)
- pinned posts by admin

When I create a new account via the yakihonne website and send a dm to my main account, then I can receive the message with the yakihonne client, but not with Amethyst.
Sending a legacy dm (I guess nip 04) on the yakihonne website then I receive also with Amethyst.

Bitcoin Safe does support signing messages, though it is a little hidden in the current version.
