If your outbound connections aren't so strongly limited, then you should be fine. Bitcoin server can work good enough even if other peers cannot connect to it. It will initiate connections and "stay in the business".

You should be aware that all bitcoin transactions are publicly available on the blockchain and any block explorer can show the transactions and content of any wallet.
Of course, from knowing what happens on an address to linking an address to a person there's still a step. And depending on how careful one is, this step will or will not happen.

You should not rely that a website doesn't keep records. It's safer to assume they do.

Iirc means "if I remember correctly".

I've checked now and made my (older) Sparrow connect to Bitcoin core, so I can give some more advises.
My blockchain is on g:\Blockchain, please adjust your path accordingly.

My bitcoin.conf looks like this:

You probably don't need dbcache setting or have to set the correct value for your computer.
I don't know if you need txindex=1 (I think/hope that you don't need it) please set it only if nothing else works (I need it for other things, it needs a full rescan i.e. a lot of time, it takes some extra gigabytes on the HDD)

Something more. You may need to create a new wallet:

And then in Sparrow it looks like this:

Bitcoin doesn't look weak to me. Transactions are processed, mining works, all looks good.
Or you mean that the volumes at exchanges aren't that great? Well.. we can't have everything.


This is the altcoins' problem/weakness. It has always been.


I don't know. But any answer you'd get would be a speculation, hence it may be better if you move this into Speculation subforum. (see bottom-left of this page).
As speculation.. some fear for the worse, some tell that a pump is near. I don't know...

I don't see any problem here. I was hobby-mining altcoins with very small hash rate and I can tell that:

* a pool can very well use (internally) more than 8 digits after the decimal point for its own needs if he wants to, for more fair splitting of the reward or if the number of users becomes very big
* a pool doesn't have to send the reward to users after each block found, that would be a waste creating a huge number of inputs in user's wallet and the usual solution is to send only after a certain threshold is passed

All in all, imho you're worrying for not existing problems.

And LN may not be needed because:
* a mining pool can mine its own transaction, hence the tx fee is not a problem
* one tx will probably contain payment for many miners in the same time, it's more practical than a lot of small transactions
* because of that threshold I wrote about the sent amounts aren't that small

I see it different. Blockchain is great for anything that "has a life" (finite or not), i.e. gets created, maybe evolves or gets transferred, maybe dies.
Logistics is a first candidate (and it's a huge "universe"). Genealogy/census/people's documents is another. Properties (especially land, buildings and other things that suffer taxation - maybe cars too) can be another.
Then blockchain is also great for anything that has to be immutable, like voting.

Of course in all these cases miners' rewards may be an issue to be handled - maybe separately. Somehow unauthorized changes have to become impossible, no matter how many individuals store those blockchains. And 51% attacks have to be also impossible. And this is hard to achieve if the blockchain itself doesn't hold value.

It's a bit late, it's almost 2 months since the report, still, a good step forward.
It looks like this will get to a happy end, after all. Please keep us posted.

In theory the price will have to get high enough to allow the mining fees suffice the miners.
In reality, if that won't happen, miners will (slowly, over the years) give up because it won't be profitable enough. But that will make the difficulty drop, hence increase the profitability for the ones remaining.
I can guess though that many things will change in more than 100 years. For example, I wound not be surprised if banks or governments will get into mining by then, and not for profit from mining, instead to keep Bitcoin running.


It's a well documented fact. But most people don't care to research/read about Bitcoin...

I guess that you want to connect Sparrow to Core and not the reverse.
I've done that once in the past, I will try to help with what I remember/find. I may not be 100% accurate.

1. Read and follow https://sparrowwallet.com/docs/connect-node.html
2. Iirc if you want to use cookie, then you may have to not use user/password in bitcoin.conf
3. You may need server=1 in bitcoin.conf (also I usually start bitcoind, not the wallet)
4. You need a wallet created in the bitcoin data server. That wallet will be loaded into Sparrow too.

... and I think that this is all.


PS. With Specter I cannot help, I am not familiar with that, sorry.

I'm not sure if OP will need this/go this far, however, I think that these are better links than what you've posted:

So you are selling an always winning script, but we should not forget that the risk of losing is there.
Also, why are you selling the script instead of making yourself all that money?

Newbies, use your brain when you see this kind of offers.

It's not easy to find a project that needs blockchain. It probably has to be free to access/store (whether the information inside is encrypted or not is another story) and it has to properly reward the miners. And maybe more...
On the other hand, the politicians heard about this kind of buzz words and started rewarding projects just because they were done on a blockchain.
And the result is that everybody wanting to store anything in a database today is first thinking "can't I do this with a blockchain" (and transform the project from dull to cool)?

While I find interesting the results of your test, now, after a good thinking, I think that it would have been even more interesting to not publish the results yet, instead do first a similar test with a couple more major HW companies. And then compare. Now some may be warned

Please don't take it as criticism. Hats off for the effort!

Yes, the seed from 3.x should work. Just make sure you have Electrum downloaded from electrum.org and verified https://bitcoinelectrum.com/how-to-verify-your-electrum-download/

Most of those "signals" you can find are scam. Their main purpose is usually to get paid subscribers.
Just think a little: why would somebody share his knowledge? If he's so good, he can trade and make money for himself. If he's not so good, he will try to monetize "signals".
Best is to learn from here and there and then trade by your knowledge - if you really can do that (since trading is not for everybody).

Ummm... no. One can claim whatever he wants, but without the private keys of those addresses no claimant can spend those coins, no matter what. Not on current bitcoin.
On the other hand, even without claiming anything, whoever has those keys can spend the money.

From what I've understood from the readme page ( https://github.com/BTCPrivate-Legacy/electrum-btcp-legacy ) this wallet is for ZClassic coin.
It also tells:


and I advise OP go to that discord and ask for help.


I would also add that I've noticed that the latest version is 1.1.1, I would update to latest version before seeking for further help, maybe OP's problem is fixed.
(Of course, backup the wallet/seed/private key/whatever before updating).

---

If OP wanted to work with actual Bitcoin I strongly suggest downloading the actual Electrum from electrum.org, verify it and import his wallet there.

All addresses and their content is visible publicly on the blockchain.
But from picking a fat address to getting its private key is a big step.
While you are free to try to "hack" it, what you do is actually wasting energy.

And no, this cannot get you a loan. For a loan you need proper collateral.

I won't say that's legit or not, but I can tell that the capture comes from this tweet: https://twitter.com/onair_blair/status/1482681573333999617
Maybe somebody can check whether it's OK or hacked/impersonated.

(Also, wasn't twitter blocking bitcoin addresses in tweets? When did that change?)

I've done a search on the news and.. it finally led to this:
