Hi everyone!

Please remember that this tutorial is no longer supported, since Sparrow version 1.9.0.

[BitcoinTalk Node Tutorial #3] Sparrow terminal / infinite Whirlpool mixes

This tutorial is not longer valid.
Since Sparrow 1.9.0 the mixing feature is no longer supported.

And what is the important of running a node?

Bitcoin is essentially a piece of software.
Nodes are computers that run this software.
Without nodes, there can be no Bitcoin.

Nodes are responsible for:
1. transmitting the blockchain to other nodes, maintaining snapshots of the blockchain.
2. validating transactions, making sure they follow the same set of rules.

Running your own node helps because:
1. you can keep a copy of the blockchain for yourself. This is brilliant, because it gives you the opportunity to "know" the truth.
2. you can validate transactions & blocks without trusting the rules that other nodes use.
3. you can be private, not asking anyone about anything.
4. you help the network. One more node is always better.

Following the latest development with Samourai Wallet , Sparrow team hurriedly released v.1.9.0


"Remove Whirlpool client, and other Soroban related features and dependencies".

They also  removed "mixing with whirlpool" section from the wallets docs.


I prefer to lose the whirlpool feature, rather than losing the wallet.
Do you think it was a wise choice? The question obviously goes to everyone who have been using Sparrow

Privacy is a fight that we can never win.

I get the point, but please remember what we are here for.
We are here for Bitcoin.
What is bitcoin? A peer to peer electronic cash system.
Who invented it? Someone who won maintaining their privacy.

Privacy is extraordinarily difficult to achieve and you only achieve a percent of it.
Privacy is also extraordinarily easy to be lost and you lose 100% of it.

But we can win... I hope!
7  Bitcoin / Bitcoin Discussion / Re: Samourai Wallet seized by the feds on: April 24, 2024, 08:16:55 PM
So my question is, since the feds control the website, is there a way to control the software that has already been downloaded to users' computers? I guess not.

So, I reckon that the whirlpool servers will go down. I also believe that there will be no more support for the products (samourai & sentinel).

Is there anything else I am missing?

It is possible that Sparrow will be the next target.

Ouch! That would hurt.
8  Economy / Trading Discussion / Re: Best Exchanges Nowadays on: April 24, 2024, 05:10:19 PM
Used to be super active but got burned by most of the old closures (Cryptsy, btc-e, Bter, etc), so where is the best place to trade nowadays?  I have a Coinbase account already along with Kraken but not sure of other options that may be better.  Thanks!

Hi. Can you define "better" ?
For me, "better" means non-KYC, but for other people "better" may mean something else, so it would help to know what you don't like with Coinbase and Kraken since these 2 are arguably the largest exchanges, so...
9  Bitcoin / Development & Technical Discussion / Re: I have 26 out of 24 mnemonic words. Am I able to brute force still? on: April 23, 2024, 04:54:52 PM
You have to place 20 words in the correct order (26 total - 6 in known places).

So how many combinations (the correct word is permutations because order matters) of 20 objects do you get ?

The first word can be in 20 positions.
The second word can be in 19 positions.
...
The 20th word can be in 1 position.

So it's 20x19x18x...x1 = 20! = 2,432,902,008,176,640,000

How fast does this get brute-forced? I will leave this to be answered by the rest of the forum. I have no idea! I was never good in brute-force stuff.
10  Bitcoin / Bitcoin Technical Support / Re: [Apr 2024] Fees are HIGH, wait for opportunity to Consolidate your small inputs on: April 21, 2024, 07:27:02 AM
Loll, I didn't realize there is an extra, I thought it was 3,600 not 3,600,000.

Just for fun, if anyone wants to see the "records" in fees (I don't know why, but I was curious to see it), you can run bitcoin-cli getblockstats <block_height>.

For instance, for the halving block (840,000):

Code:
>> bitcoin-cli getblockstats 840000
{
  "avgfee": 1234031,
  "avgfeerate": 3770,
  "avgtxsize": 762,
  "blockhash": "0000000000000000000320283a032748cef8227873ff4872689bf23f1cda83a5",
  "feerate_percentiles": [
    108,
    134,
    200,
    350,
    1063
  ],
  "height": 840000,
  "ins": 3764,
  "maxfee": 799987800,
  "maxfeerate": 3604819,
  "maxtxsize": 166989,
  "medianfee": 34800,
  "mediantime": 1713570208,
  "mediantxsize": 266,
  "minfee": 2060,
  "minfeerate": 15,
  "mintxsize": 150,
  "outs": 9716,
  "subsidy": 312500000,
  "swtotal_size": 2318332,
  "swtotal_weight": 3964249,
  "swtxs": 3023,
  "time": 1713571767,
  "total_out": 135995397232,
  "total_size": 2325218,
  "total_weight": 3991793,
  "totalfee": 3762561499,
  "txs": 3050,
  "utxo_increase": 5952,
  "utxo_size_inc": 450713,
  "utxo_increase_actual": 3919,
  "utxo_size_inc_actual": 308963
}

The "maxfeerate": 3604819 indicates the fee record on this block which was 3604819 just like BlackHatCoiner mentioned above in the discussion.

Hi NotATether.

My offer must be withdrawn unfortunately.

The fees for on-chain are too high to be ignored, so I need to use the LN funds to buy something that I need.

12  Bitcoin / Bitcoin Discussion / Re: Happy 4th Bitcoin Halving on: April 20, 2024, 08:16:19 AM
Yeap, my node confirms. We are officially in a new epoch:

Code:
> bitcoin-cli getblockstats 840000

{
  ...
  "blockhash": "0000000000000000000320283a032748cef8227873ff4872689bf23f1cda83a5",
  ...
  "subsidy": 312500000,
  ...
}

13  Bitcoin / Development & Technical Discussion / Re: An unexpected backup system suggestion on: April 20, 2024, 06:49:02 AM
Or even worse, why wouldn't that someone tie him up and torture him until he gives them what they want? At that point, it doesn't really matter what you used for your backups.

One of the best ways to protect your coins is really not to tell anyone that you have bitcoin, at least not unnecessarily

Guys, I completely agree with these comments.
Jameson Lopp has a great resource on github where he keeps a list of all the physical bitcoin attacks. Just read it and you will notice that there have been many "torture / threat" stories. This is a huge threat that people seem to ignore.
14  Economy / Currency exchange / Re: WTB $30 in LN sats, have BTC on: April 18, 2024, 09:21:59 AM
I'll figure out how (and when) I'm going to move 200k sats to my LN node so that I can open a much larger channel. Or, I might open 2 100k channels each in order to have a fallback in case my node decides to close the connection for some reason. btw, can LN channel closures happen automatically? I have only ever heard of the case where it is initiated manually.

(I have Terminal Web which makes the process of opening channels much easier.)

I am not aware of auto closures. So can't really comment on that.

Personally I have 3 open channels with 3 very large nodes. The reason behind this decision is to make sure there will always be a route to process payments.

So, when you want to do the trade let me know. In case I use my funds meanwhile, I will post here to withdraw my offer. I think I won't need to do that, but if I do I will let you know.
15  Economy / Currency exchange / Re: WTB $30 in LN sats, have BTC on: April 18, 2024, 09:02:27 AM

I use the Alby browser extension which is connected to my Voltage LND node.

It seems that my only channel has been closed automatically somehow. So I will need to open another channel or you might need to open a channel to my node. (I only have 22K sats on-chain withing the lightning node which I don't think is enough to open a channel. I think you need at least 10x that amount to open a channel with that liquidity but like I said, fees are stupidly high right now and my lightning node's addresses do not have enough funds in them.)

My node's public key is 03e2b8f741b13d0746816a2a609032e4da6729347835e574d9407b7dd183face65 in case you need that info.


I don't have the funds to open a channel unfortunately. I would use my custodial LN wallet for this purpose. My self-custody LN node has been idle for a long time and I don't wish to use it right now. The fees are very high so opening a channel would cost a lot.

So in your case, you have a self custody LN node which means that you handle the channels and the liquidity.

You don't have an open channel so there is no way for the payment to be routed.

Even if you open a channel somehow with me, or with any node and even if there is a direct or indirect route between our nodes, you still must have more than 46k sats inbound liquidity, in order to receive 46k sats.

Let me know if you need further explanation.
16  Economy / Currency exchange / Re: WTB $30 in LN sats, have BTC on: April 18, 2024, 07:59:01 AM
Right. My bad. I am still learning to get the hang of LN.

Yeah that's a good decision. There seems to be a problem with the invoice. Did you include a payment amount?

I could assist you if you need help. My wallet doesn't recognise the invoice. Which wallet do you use?
17  Economy / Currency exchange / Re: WTB $30 in LN sats, have BTC on: April 18, 2024, 06:25:22 AM
I can help you if you want.

I am able to send 46,000 sats. If that's ok with you, let me know.

Yes, please post the LN invoice here.

Wait, I thought you wanted to get LN funds and return on-chain. Am I wrong? If I am right, then you have to paste the LN invoice and I will pay it the sooner possible. If it is a QR, it's even better. Remember to create an invoice for 46,000 sats.

Could you provide me with the appropriate instructions to achieve that?
