FROST multi-sig Cashu wallet
Very basic proof-of-concept. This uses FROST signatures, coordinated over Nostr, to sign a Cashu transaction which spends collaboratively from the wallet via the threshold signatures (e.g. 3-of-5) of FROST. This includes a basic web app where the signers can approve the signature and construct their signatures via Nostr

...............................33 years old.............................
A Cypherpunk's Manifesto
by Eric Hughes
Privacy is necessary for an open society in the electronic age.
Privacy is not secrecy. A private matter is something one doesn't
want the whole world to know, but a secret matter is something one
doesn't want anybody to know. Privacy is the power to selectively
reveal oneself to the world.
If two parties have some sort of dealings, then each has a memory of
their interaction. Each party can speak about their own memory of
this; how could anyone prevent it? One could pass laws against it,
but the freedom of speech, even more than privacy, is fundamental to
an open society; we seek not to restrict any speech at all. If many
parties speak together in the same forum, each can speak to all the
others and aggregate together knowledge about individuals and other
parties. The power of electronic communications has enabled such
group speech, and it will not go away merely because we might want it
to.
Since we desire privacy, we must ensure that each party to a
transaction have knowledge only of that which is directly necessary
for that transaction. Since any information can be spoken of, we
must ensure that we reveal as little as possible. In most cases
personal identity is not salient. When I purchase a magazine at a
store and hand cash to the clerk, there is no need to know who I am.
When I ask my electronic mail provider to send and receive messages,
my provider need not know to whom I am speaking or what I am saying
or what others are saying to me; my provider only need know how to
get the message there and how much I owe them in fees. When my
identity is revealed by the underlying mechanism of the transaction,
I have no privacy. I cannot here selectively reveal myself; I must
_always_ reveal myself.
Therefore, privacy in an open society requires anonymous transaction
systems. Until now, cash has been the primary such system. An
anonymous transaction system is not a secret transaction system. An
anonymous system empowers individuals to reveal their identity when
desired and only when desired; this is the essence of privacy.
Privacy in an open society also requires cryptography. If I say
something, I want it heard only by those for whom I intend it. If
the content of my speech is available to the world, I have no
privacy. To encrypt is to indicate the desire for privacy, and to
encrypt with weak cryptography is to indicate not too much desire for
privacy. Furthermore, to reveal one's identity with assurance when
the default is anonymity requires the cryptographic signature.
We cannot expect governments, corporations, or other large, faceless
organizations to grant us privacy out of their beneficence. It is to
their advantage to speak of us, and we should expect that they will
speak. To try to prevent their speech is to fight against the
realities of information. Information does not just want to be free,
it longs to be free. Information expands to fill the available
storage space. Information is Rumor's younger, stronger cousin;
Information is fleeter of foot, has more eyes, knows more, and
understands less than Rumor.
We must defend our own privacy if we expect to have any. We must
come together and create systems which allow anonymous transactions
to take place. People have been defending their own privacy for
centuries with whispers, darkness, envelopes, closed doors, secret
handshakes, and couriers. The technologies of the past did not allow
for strong privacy, but electronic technologies do.
We the Cypherpunks are dedicated to building anonymous systems. We
are defending our privacy with cryptography, with anonymous mail
forwarding systems, with digital signatures, and with electronic
money.
Cypherpunks write code. We know that someone has to write software
to defend privacy, and since we can't get privacy unless we all do,
we're going to write it. We publish our code so that our fellow
Cypherpunks may practice and play with it. Our code is free for all
to use, worldwide. We don't much care if you don't approve of the
software we write. We know that software can't be destroyed and that
a widely dispersed system can't be shut down.
Cypherpunks deplore regulations on cryptography, for encryption is
fundamentally a private act. The act of encryption, in fact, removes
information from the public realm. Even laws against cryptography
reach only so far as a nation's border and the arm of its violence.
Cryptography will ineluctably spread over the whole globe, and with
it the anonymous transactions systems that it makes possible.
For privacy to be widespread it must be part of a social contract.
People must come and together deploy these systems for the common
good. Privacy only extends so far as the cooperation of one's
fellows in society. We the Cypherpunks seek your questions and your
concerns and hope we may engage you so that we do not deceive
ourselves. We will not, however, be moved out of our course because
some may disagree with our goals.
The Cypherpunks are actively engaged in making the networks safer for
privacy. Let us proceed together apace.
Onward.
Eric Hughes

it's overwhelmingly an infrastructure play, not a response to immediate, widespread worry. The actual use case is to create a real-world testing ground and a future-proofing option for high-value assets.
The key critical components of Liquid—like the Bitcoin peg, confidential assets, and the network's consensus—still rely on classical cryptography and remain vulnerable . This single test does not make Liquid a "quantum-resistant network."The Blockstream team is essentially building a "quantum-resistant sandbox" on top of Liquid.....

2026-03-07 21:39:08 UTC

Blockstream has broadcast what are, to the best of our knowledge, the first transactions on a production #Bitcoin sidechain signed with a post-quantum signature scheme. Real transactions securing real value on #Liquid mainnet. This works not only with bitcoin, but also with any asset issued on Liquid.

AAron Rainbolt:
I propose that the exact way in which age information is stored by the
daemon should be left implementation-defined. For Kicksecure, the way
we implement it will almost certainly store only the age bracket and
require users to explicitly reconfigure their age once they are old
enough to move from one age bracket to another. Other implementations
may choose to store the date of birth or the age and date on which the
age was set so that they can automatically update the age bracket as
time passes. This interface will be provided *on the system bus* (NOT
the session bus!), and the D-Bus service that provides these services
should run as root. The file containing the user-to-age mappings should
be owned by root and should not be world-readable, to prevent leaking
the user's specific age to malicious applications.

No big surprises anywhere last week, so 6.19 is out as expected - just
as the US prepares to come to a complete standstill later today
watching the latest batch of televised commercials. The betting man
would expect them all to be AI-generated, but maybe some enterprising
company decides to buck the trend? Doubtful, but there's always a
slight chance.
But for anybody outside the US, maybe taking the newest kernel out for
a spin instead is an option?
I have more than three dozen pull requests for when the merge window
opens tomorrow - thank you to all the early maintainers. And as people
have mostly figured out, I'm getting to the point where I'm being
confused by large numbers (almost running out of fingers and toes
again), so the next kernel is going to be called 7.0.
But today, the big news is 6.19. And some random sporting event.
