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.

Users can reasonably assume that all operators act in concert.
https://mibo.nostria.app/4c4e19959486dd0a8edc90c3d7a0aa2eb003aba4ea0482997bd80587a346f401.jpeg
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...🤡
Normie life project finished. Boo🖕 https://hortopato.cc/1f39d34bb5b400c122edb6e589cb1a3084581d3fe4303e91a6cc954cc4b31bec.jpg
It is not plausible that Spark are not running screening and analysis on Spark data and transactions.
That tweet came with an explanation:
https://blossom.primal.net/f4e0f78db4c18bdc8a7e72bcff3d1122fdc84c57bc1e24c32a3494dd22a54aa0.jpg
This is the stated trust model.
At least there is not one operator, but 3 currently with more possible.
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.
You're technically correct.
The operator can withold the recovery bundle.
From a user perspective, this is the equivalent of freezing funds.
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.
Costs, lessons, code and txIDs onchain: https://www.blink.sv/blog/case-study-spark-unilateral-exit-on-bitcoin-mainnet
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.

I was thinking whear are you when we talk about spark... 😉🤣
Yes, fees to exit unilaterally should be comparable to Ark as it also uses this kind of transaction chain to be broadcasted.
There are many variables which can be tweaked:
- number and sie of the leaves/vTXOs
- depth of the chain to broadcast
- timelocks
- fee/rate
Ark solutions have this periodical onlineness requirement and ongoing fees for rounds as wrll which make them have different tradeoffs.
Spark works now, but no wallet should be locked in to it. Let it and the alternatives evolve. Our job is to keep our eyes open and assess the risks.
But is this something that e.g. Wallet of Satoshi should be doing proactively? Either when transactions are made, or wake up daily to do consolidation or something. I don't understand the details well.
If we can help in any way with testing we will!
Dude if you do this you'll make me the happiest man ever. We've been trying to think of ways around it and we did think of a hack but we don't think it could be relayed. Official cluster package relay would be a game changer for users.
Yes, the feature was added to our tool today: https://github.com/blinkbitcoin/spark-unilateral-exit/pull/11
The consolidation comes with a tradeoff between efficient unilateral exit and fast transactions (lacking denominations will need more swaps with SSPs at payment time).
https://blossom.primal.net/64292f781d0778d13692bdb0f94521b4a16e92cb053734aa26ae6310e61b199b.png

I've abandoned budgeting years ago. Since I've bacame bitcoin billonaire. Just joking 😁 (I never stopped budgeting despite of my billions😁)
I stopped using Spark wallets many months ago... 🤷♂
Basically, if something happens in Spark, the miners will be very happy... 😅
I strongly recommend @Zeus (LND embedded), which now works really well... 😎👍

Do you think Spark and Ark require comparable fees to exit unilaterally? Have you seen a similar study for Ark?
This data liveness requirement is painful but I think comparable to the pain of expiring VTXOs in Ark. There you already always have the state to publish for the unilateral exit but you (wallet or watchtower) must monitor the expiry deadlines.
Of course the other thing is that ark operators are less trusted since they cannot conspire to steal funds.
However I still love Spark because at the end of the day operators don't have enormous liquidity requirements and this will make a big difference in adoption.
Also in Ark has that constant periodical refresh from user wallets, that doesn't look good to me. I don't necessarily open my wallets every month and this is going to be a problem when a lot of users realize this (or have to pay extra for a refresher service).
All in all love the innovation of the L2 space
Ark (bark) launched like couple weeks ago. Spark had head start. I haven't followed arkade recently...
Can the wallets be optimized to always try doing the lowest number of leaves? So when you actually need to exit, it's only a couple...

Correction: "seed only, no operators" compressed two steps. The leaf data (recovery bundle) must be fetched while operators are online. The exit itself then needs nothing from them: seed + saved bundle is the accurate claim. Full mechanics and costs: https://github.com/blinkbitcoin/spark-unilateral-exit/blob/main/docs/mainnet-exit-case-study.md

Yes, correct, one either keeps a server up with their seed or the mobile does it.
In Blink we will have event-driven and likely also periodical refresh built in.
The data-availability dependency is real and worth stating exactly, so let's state it.
Operators never hold your key and can't move funds without your signature - that part is unconditional. Unilateral exit works through pre-signed refund txs that pay to a key only you control, and those txs plus their ancestors are the "leaf data" in question: your device co-signs them at claim time, ancestors come from a query. Until a wallet persists that data, forcing your funds on-chain depends on operator liveness. Grubles is right that no wallet ships this today. That gap is the entire reason I built and published this tooling instead of just claiming "non-custodial" in marketing copy.
What the dependency actually is, once you persist the data:
Bounded: everything covered by your last refresh exits without any operator, forever. Exposure is only what changed since then. With refresh wired into every claim, that window is one transaction.
Detectable: withholding means your refresh fails right after your claim succeeded. You notice, you stop receiving, you exit with what you have. - Compare a custodian, where withholding looks like normal operation until the withdrawal freeze.
So on the spectrum: weaker than Lightning, where your node holds channel state by construction. Much stronger than custodial, where they hold both keys and data and you detect nothing. "Self-custody of keys with a bounded, detectable data-availability dependency" is the honest label.
Wallets that don't manage that dependency for users are shipping the weak end of the spectrum. Mine included, today. That is what is being fixed, and the case study is the receipt that the exit half already works:
https://github.com/blinkbitcoin/spark-unilateral-exit/blob/main/docs/mainnet-exit-case-study.md

#nevent1q…9lqe
The only way to get the offchain data from the operators why they are online.
Wallets should (Blink will) implement periodic background polling for data.
Find the case study here if getting 404 from github:

The repo was just made public, might be lagging to show:
https://github.com/blinkbitcoin/spark-unilateral-exit
I just force-exited a non-custodial Blink wallet (using Spark) on Bitcoin mainnet.
Seed only - no operator cooperation: recovery bundle, fee funding, CPFP signing and sweep all derived from the wallet seed.
The honest numbers for a 100k sat wallet:
• 22 leaves, 253 tx packages to exit fully
• only 4 leaves (90% of the value) were worth exiting - fees would have eaten the other18
• ~9.4k sats in fees to recover 90.1k, one package per block per chain, then a ~2-week timelock
Non-custodial means you can always leave. But the fire escape is narrow - full case study with costs, failures and lessons:

If you are up for doing some Bitcoin research, you can join this experiment on the default signet chain on Wednesday:
https://delvingbitcoin.org/t/consensus-cleanup-demo-of-slow-blocks-on-signet/2367
Syncing signet on an RPi5 should take less than an hour (but allow a little more time just in case).
You can start the signet bitcoind instance on a Raspiblitz by running:
config.scripts/bitcoin.install.sh on signet
You will have these aliases set in terminal for easy monitoring and configuration:
alias sbitcoin-cli="sudo -u bitcoin /usr/local/bin/bitcoin-cli -rpcport=38332"
alias sbitcoinlog="sudo -u bitcoin tail -n 30 -f /mnt/hdd/app-data/bitcoin/signet/debug.log"
alias bitcoinconf="sudo nano /mnt/hdd/app-data/bitcoin/bitcoin.conf"
The systemd service is called: sbitcoind
so can check and restart with:
systemctl status sbitcoind
sudo systemctl restart sbitcoind

Neither is true. Christianity is the continuation of the covenantal relationship between the God of the universe and mankind through Abraham, where God is establishing his work in us and by us through his Son and by his Spirit. Jesus is essential for our restoration and to end the rebellion, but it isn't strictly speaking about Jesus. If Alan Watts didn't understand this nuance, he didn't understand Christianity.

The Lightning Network is a second-layer protocol built on top of Bitcoin's stable base layer. Unlike Bitcoin, Lightning does not have its own blockchain, so it does not require a consensus mechanism. Instead, it relies on agreed-upon accounting and security guarantees between peers to maintain payment channels.
On the Bitcoin network, consensus rules determine the validity of blocks. While mempool relay policies do not influence these rules, they can fragment mempools and significantly delay full block relay.
Many non-technical and often non-economical participants are misled into believing they can influence consensus rules through relay filters. This is not only inaccurate but also potentially harmful to the network.
