Az elmúlt hónapokban sokat esett a Bitcoin árfolyama. Sokan már temették a négyéves ciklust, aztán beköszöntött a medvepiac. Szó esik a 200 hetes mozgóátlagról mint történelmi mélypontról, egy 80 százalékos zuhanásról, és arról, hogy kik számára lehet jó hír egy leértékelés.

It is not plausible that Spark are not running screening and analysis on Spark data and transactions.

I don’t know about you, but they didn’t ask me… But of course, I’d like to give even more power to the state and even more centralization—that’s the solution. I wouldn’t be able to protect my child myself anyway...🤡
This is the stated trust model.
That tweet came with an explanation:
https://blossom.primal.net/f4e0f78db4c18bdc8a7e72bcff3d1122fdc84c57bc1e24c32a3494dd22a54aa0.jpg
Users can reasonably assume that all operators act in concert.
At least there is not one operator, but 3 currently with more possible.
You're technically correct.
The operator can withold the recovery bundle.
From a user perspective, this is the equivalent of freezing funds.
The operators can freeze the service, not the funds.
Exit txs are pre-signed: with a saved recovery bundle the unilateral exit needs zero operator involvement. That's exactly what we tested on mainnet.
Caveat, stated in the post: the bundle must be saved while they still serve you.
The operator can freeze your funds.
By "all operators colluding for theft" I mean all of these at once:
- every operator keeps its key share for a previous state of the leaf instead of deleting it
- all of them sign with those old shares - even combined, that is still not a full key
- they also need the previous owner of the leaf to sign, or to be that previous owner themselves
There are real cases where the SSP is the previous owner, so in practice it reduces to: you are trusting at least one operator to actually delete previous states. That is the stated trust assumption.
Not trustless, and the post does not claim it is.
I'm getting confused by all of this trustodial stuff: can a single Spark operator spend your funds and hence rug-pull you? Can a subset of operators do it?
That doesn't get the point across as clearly. Someone might misinterpret "alone" this way:
Operators can never spend their coins without your permission
Clearly stating that they are taking on the risk of theft is the only ethical way to present it.
The updated text says:
Operators can never spend your funds alone.
One operator is certainly insufficient.
There's a typo: It should say "The operator CAN spend your funds"
Can you actually leave?
We tested it on mainnet: forced a 100k sat Blink wallet out of Spark, back onto Bitcoin.
No operators, just the seed and a saved recovery bundle.

Trust model reiterated. In-app exit next.

From what I've heard for example Cake wallet is just waiting for Breez SDK to add it then it's a simple matter of including it in the wallet UI. Supposedly it will be soon. Not sure about wallets that use other Spark implementations but I'm guessing it's a similar reason they don't have it yet either.
You can exit with seed only if your wallet took care of saving the recovery bundle while operators were online and willing.
We will have this safeguard in Blink shortly and hope to see it in other Spark based wallets too.
Kedves @nprofile…rf49 , a satoknak jobban örülnénk, de eljuttatom a kérést az illetékeseknek. Üdv
Dont know, but possible 🤷♀️
The women of The Odyssey pose on the red carpet! 😎 😅
