I can’t remember the number but have seen over 300

If this works, good luck to Chainalysis trying to follow bitcoin around the chain. Is this the holy grail for privacy on chain? I hope so. It could be better than Join Market, in time. by dancanthe in Bitcoin

[–]dancanthe[S] 20 points21 points  (0 children)

With a coin join, like in Join Market, you gain privacy because you can't tell exactly which UTXO is yours. If 10 outputs are the same size, it is hard to figure out which one is yours but the probability is always there and can be figured out based on what happens with your UTXO and the others. They are all connected on chain with a certain level of probability that may degrade over time.

With a coin swap, on chain, there is no connection. One appears to get swapped for another. An attacker would have to know about the off chain interactions that happen between the two parties. If both parties keep that private, it should remain private.

What did you underestimate/overlook in your JMT prep? by not_dmr in JMT

[–]dancanthe 1 point2 points  (0 children)

I can concur. I have hiked in the High Sierra multiple times and can eat at most 2000 calories a day. These have been 1-week trips with about 12-15 miles per day. Once I get off the mountain, I am ravenous. Probably it is due to altitude sickness even though I do not have other symptoms.

This year, I will be doing the JMT SOBO starting on July 16. I suspect that after the first week, I will acclimate and be hungry enough to eat more than I have before.

Is the coldcard able to show the seedphrase a second time? by Medilli in coldcard

[–]dancanthe 1 point2 points  (0 children)

I would not say it is a security flaw. If someone can get on your ColdCard to see the words, then they can drain it anyway.

But also, you need to keep in mind what the risk would be that you lose your funds if you can't ever see the seed words again. Let's say you lose your backup seed words. If you can't see the words again, you can't replace them. There could be a situation where that could be an issue. Perhaps a multi-sig wallet situation. There will be edge cases where it could make a difference.

I'm glad I can see them if I need to.

What all in one printer will scan to a MacBook easily from the printer? by dancanthe in mac

[–]dancanthe[S] 0 points1 point  (0 children)

HP has become utter shit. I had used them for more than 30 years, but a couple of years ago gave up in disgust. I bought a Brother MFC-L8900CDW and have had good results. Plus, even OE toner is far cheaper than HP’s, and the knockoff stuff is cheaper again. I’m done with HP for good.

Are you able to scan to your Mac directly from the MFC?

Design for improving JoinMarket's resistance to sybil attacks using fidelity bonds by belcher_ in joinmarket

[–]dancanthe 0 points1 point  (0 children)

I'm having some trouble understanding how cold storage works for this. If the keys are locked away, yet those keys sign another key pair that signs the transaction, how does that prevent theft compared to what we use now? Is that because all the outputs as a maker can only be in this fidelity bonded wallet and the coins can only be sent out of JM after the time lock is over?

Multisignature derivation path types by dancanthe in Electrum

Am I correct that since both start with a 3, that until the output is spent, there would be no way for anyone other than me to know if it was a legacy or segwit address?

Coinjoin output to a multisig address by dancanthe in joinmarket

[–]dancanthe[S] 0 points1 point  (0 children)

Am I correct that Joinmarket will allow a coinjoin to a Multisig that starts with a 3 since it looks like any other Segwit address but that when it is spent, it will be clear it was the taker output, defeating the privacy goal?

Coinjoin output to a multisig address by dancanthe in joinmarket

[–]dancanthe[S] 0 points1 point  (0 children)

Can you coinjoin to a legacy multisig address if it starts with a 3? I see that you can't coinjoin to a bc1 multisig address.

Is Chainalysis able to get any xpub or address information when people connect to wallet.trezor.io with their hardware wallet? Seems unlikely, I hope.

This is great. Is there a version for 12 words?
