Bitcoin & šŸ«‚ Oh and dimly trying to think through interesting issues. I think that I don’t have a right to force you to do anything other than not harm me or others. Seems like most people I interact with in the real world disagree with this statement. To be fair.. the devil is in definition of ā€œharmā€.

That’s some cheap acreage! $21 per acre. No property tax. Basically no maintenance. No views though 😢

(Of humans) likely that the rich will possess the surface of the earth

Looks like all ducks are in a row for the next orbital test launch of starship

What is Payjoin V2, why do we need it now, and how does it make payjoin so much easier to support?

Basic #bitcoin transactions are non-interactive. An address is all a sender needs to send bitcoin.

The trade off is that only the sender can contribute inputs that the receiver must consolidate later, and third parties assume all transaction inputs come from just one sender.

Payjoin peers instead interact before they broadcast a transaction. That way they both can spend inputs in a batch. Batch transactions share fixed fees and save money. They break probability analysis used to track bitcoin.

However, V1 receivers must host a server online.

Payjoin V2 peers may go on and offline and still make a payjoin. V2 lets even web wallets receive payjoin any time to optimize for fees and default to better privacy.

An oblivious third-party directory hosts a server instead. The directory can't steal or even see peer IP addresses.

Oblivious HTTP keeps IP addresses private. It works like Tor with just 2 hops on a pre-defined route.

The OHTTP Relay just sees encapsulated requests.

The Payjoin Directory sees requests without Client IPs.

The Directory can't see request PSBT contents. They're encrypted too.

Payjoin V2 keeps message contents private between sender and receiver without involving a certificate authority. The Payjoin Directory cannot see transaction details.

Hybrid Public Key Encryption makes end-to-end authenticated encryption with tools already native to Bitcoin.

Payjoin only works when we choose to support it. Join me by paying this knowledge forward.

Special thanks to BitDevs NYC for giving these slides their first audience.

I suppose we now commence waiting for wallet support?

Yeah there is a reason we see no snow buildup on the roof šŸ˜„

True. Though, the article relies surprisingly (to me) heavily on them manually recreating your brain structure. If that’s the way it turns out, it’s not all bad.

Knowing your brain structure is a prerequisite for both accessing the funds (knowing structure + decoding structure) and for reconstructing you (knowing structure + actually rebuilding structure). It’s not a total loss to be able to for sure give them a huge bounty in figuring out how to map the structure. They may find it easier to map then recreate then ask than map then decode. Kinda doubt that though.

The worst would be them being able to map and decode but not reconstruct any time soon. That could be a huge motivation to saw you apart and not reconstruct you.

This slide highlights a misunderstanding that a lot of people have with LLMs. We aren’t used to interacting with entities that know as much as it does about the world, and simultaneously as little as it does about you specifically.

More context = less dependence on what the training group thinks the AI should be like, more on what you are looking for.

My fu is lacking. Can’t seem to find whether any clients support this? Every reference I saw to 06 was either standalone code or documentation on it.
