*A̶I̶ A poll

Milei is still a reasonable shot for the runoff on Sunday-week (19th). Al showed him picking up a fair share of former Bullrich supporters.

Example: Ensuring Secure Cosigning

🔐 Imagine you have a wallet descriptor listing this cosigner's xpub:

xpub6EDJac9G93fFKuJsXRfBwJ45APnGTg4VwqEHmaLTrfXy18QzMSRiRVxcTdKhhpKNPPdo6Ct3j9xte8ciuLYxHYdLvixXqpHpDg8x5JfNn4k

🗳️ You ask your cosigner to sign a message, "Forever, Laura.", using a key derived from their corresponding xprv with the path /0.

🔍 You calculate the public key: 039a23c735abd0610aaf89fe356a860b65545c571bdaece7a82260e5f207a77185.

💰 And from this, you obtain the Bitcoin address: 1LrH1NQb5HeXffFtpuXNkHZavyXjt57VFX.

🛡️ Your cosigner's wallet software (Sparrow, Nunchuk, Coldcard, SeedSigner, or others) derives the private key using the full path, e.g., m/48'/0'/0'/2'/0, and uses the resulting private key to return this signature:

🔍 You verify this signature and gain reassurance that your cosigner is ready to stand by you.

Here's how I would like to confirm that my cosigners are competent.

Step 1: Prepare a Unique Message

📝 Prepare a unique and freshly generated message that you will provide to your cosigner.

Step 2: Specify Derivation Path

🔑 Define the derivation path for your cosigner.

Step 3: Request Cosigner's Cryptographic Signature

🔒 Share the message, the derivation path and the participating xpub with your cosigner and request a cryptographic signature from them.

Step 4: Cosigner's Action

🖋️ Your cosigner signs the message you provide, using a key derived from the xprv partner to their xpub.

Step 5: Calculate Public Key

🔍 Calculate the public key by applying the specified derivation path to their xpub.

Step 6: Verify Signature

🛡️ Verify the signature's validity using the derived public key.

Step 7: Establish Trust

🤝 If the signature is valid, you can trust that your cosigner maintains control of their key.

What is your preferred way of checking that a cosigner can still sign a multi-sig transaction with you?

Well earned! Was the brisket enough to satisfy you?

Massa is the narrow favourite now, according to betting markets. 😒

What will Bullrich/Schiaretti/Bregman voters do when Milei and Massa go head-to-head next month?

Thanks. Gambling is high time preference but I couldn't resist punting on the referendum. I enjoyed sharing it with a few woke lefties for a laugh. They were sad and insulted! One dope suggested that I bet on yes because I could win more. Lnmarkets is a bit like Betfair, I think.

Taking what I won from betting on the voice referendum and using it to back Milei in this weekend's election.

Can you join us at the Brisbane Bitcoin Meetups on the first Thursday of every month?

Onya, Jen, and glad to see you on Nostr now!

Lovin' both of these.

Thanks for the support, blokes! I'll definitely bring some to the meetup. ☺️

Brewed in tribute to Javier Milei and in anticipation of his victory in the impending Argentinean presidential election.

Thought-provoking! I like to think that convincing responsive/interactive renditions are a ways off yet. Maybe not though. My mind went to the following when Bender spoke with God.

BENDER: So, do you know what I'm gonna do before I do it?

GOD: Yes.

BENDER: What if I do something different?

GOD: Then I don't know that.

I tried refreshing and now it says that there's nothing to see.
