Noticed I’m not using Nostr nearly as much as Twitter… I think mostly because Twitter is where the newbies and Bitcoin-curious are, whereas Nostr is largely a crowd of the converted

And why does #[2]​ have a person-check while everyone else seems to have a verified check?! 😅

#[0]​ what do the blue/yellow star and bolt mean? Bit confusing feature discovery, suggest something like a tooltip when tapped/long-pressed just to explain it. Verified-like check mark probably also still confusing for new users, so same could work for those

What is #Ledger Recover, should you be worried, or is it for you?

How much do you understand about Hardware Wallets?

Do you know this would work on a ColdCard?! Private key extraction through a firmware change has always been possible.

Where is the BRC20 spec? How are these tokens minted? Who is minting them with what software? How are they traded?

Feels impossible to have an informed opinion without knowing all this, and seems hard to find answers

#Bitcoin #ordinals #brc20

Anyone know anything about tbdxxx other than it’s a thing? (Proposed alternative #Bitcoin layer 2 similar to #lightning )

AFAIK Nostr DMs are still not great, switching to Diffie-Hellman double-ratchet or a similar more secure and private system is a must

Hrm, don’t really want to start this argument up again 😅 but SeedSigner has a lot more hardware risk than a ColdCard, except (perhaps) for targeted supply chain attacks — because a SS is widely available off the shelf stuff, it has ‘herd safety’ whereas CC is obviously only for Bitcoin so has a clear incentive to be attacked. SeedSigner is also more closed hardware than the ColdCard is (RasPi is very closed), though neither are fully open as CC give schematic but PCB layout is closed and Secure Elements are mega closed and the ST Microprocessor is also closed.

Similarly, for the software risk, ColdCard software stack is way way fewer (orders of magnitude) lines of code than what’s in a SeedSigner which AFAIK is running an entire Linux. CC firmware can be deterministically built, whereas SS doesn’t and that might be tricky to achieve.

So while both are great, they have slightly different security characteristics and for *most people* the ColdCard comes out as the stronger option

Can someone tl;dr the drama?

Really struggling to see the attraction of eCash on Bitcoin…

The Bitcoin itself is custodies by the mint, so there’s standard custodial counterparty risk. Mint rugpulls = money gone

But also, I have to keep my eCash tokens secure and not lose them, just like Bitcoin self-custody. Lose tokens = money gone

So surely eCash has the downsides of both custodial and non-custodial Bitcoin/Lighting?

Saying the mint would be run by trusted local people is a cop-out, still relies on trust and being able to kneecap someone if they try rug…

Also a kinda, Fedora CoreOS https://docs.fedoraproject.org/en-US/fedora-coreos/getting-started/

Only feedback is using public notes vs DMs feels spammy, but in fairness that has helped it gain traction (otherwise no one would know everyone else is using it)

Welcome! 🤙

Yes, think so - you’d put all the different unlocks in a modified BIP199 HTLC script?

Something like

```

OP_IF

[spend with a pre image (hash)]

OP_ELSE

OP_IF

[spend with some multisig and CLTV]

OP_ELSE

[spend with weaker or other multisig and longer CLTV]

OP_ENDIF

OP_ENDIF

OP_EQUALVERIFY

OP_CHECKSIG

```

Can the Blue one have a special trick mode where you can opt to store an Ethereum key on it instead during setup and it just bricks itself?

Please stop making things I feel compelled to spend sats on it’s annoying

Echo chambers are fucking boring, please keep having a variety of people on for interesting chat and ignore the whinging 🤙

I wrote a thing about Ordinals:
