I don't know how Sparrow works. I've never used it, but in theory if it has access to the BTC node (being on the same network) it should work. But the transactions created will only be advertisements and will enter the mining queue when the node has internet.

2025-04-29 21:02:05 UTC

- reply

Only the BTC node works normally. When the internet comes back, it will update the blockchain and start working again. It can even generate transactions without internet on the node, but they will only be advertisements when there is internet.

Yes, it is possible. I think the market definition may already cover this use. But I think anonymity is a bit problematic. I wouldn't rent my property to someone I don't know, it's not safe. Without a third party to guarantee and mediate the transaction, it becomes much more complicated and risky.

Something centralized doesn’t scale. It can’t meet demand when the number of users grows. User reports are faster and more efficient than an AI algorithm to analyze photos.

Something we can call community notes. NOSTR already has support for reporting this type of profile. It depends on the relays identifying the profiles and not returning their notes.

Use Tor then. Umbrel has the option to use Tor.

2025-02-07 11:06:30 UTC

- reply

It is also possible. But it is more complex. And the public IP is not yours, it is from the operator, and it will change periodically. If you define very strict rules on your router you will not have any major problems. One option that may be of interest is Umbrel. It comes with everything ready.

To mention someone, you need to enter the person's npub. Some clients create this feature using @ and name. So it depends on the client you use. For example, in Amethyst, I've noticed that it only suggests people who interact or are in the conversation who will respond.

Follower numbers are not obvious and not easy to count. No client will show you the exact value, they are just estimates

2025-01-30 09:46:57 UTC

- reply

I have a Coinos account and I couldn't make a ZAP on this note. I think it's because of the capital R that is written in your profile address. The rules are case sensitive.

2025-01-30 09:43:53 UTC

- reply

I also suspect not. Even the nip-96 or blossom server returns the nip94 event but I think Amethyst does not subscribe to it and does not send it to the relays.

With the current low fees, it ends up being cheaper to send from the exchange to the cold wallet when it exceeds 1000 dollars.

2025-01-25 16:36:50 UTC

- reply

If you have any doubts about how to store your purchases in small quantities, I leave them on the Exchange while they are less than $1000. Above $1000 I transfer them to a lightning wallet. Above $5000 I transfer them to a cold wallet.

2025-01-25 11:07:16 UTC

Sharing and interacting is only helping these people. The best thing to do is to report on the app and block.

2025-01-23 14:12:01 UTC

- reply

The final half takes more than twice as long as the first half. There is the option to download all the blocks in zip and unzip them. It would speed up part of the process. The longest time is not the download but the processing of the blocks.

You have to fill out your profile with your lightning address. It is usually something similar to an email.

2025-01-22 16:07:10 UTC

- reply

I don't think of NOSTR as content creators and consumers. For me, this concept has already been overcome and proven not to be functional in the long term.
I see NOSTR as interaction between people, some seeking help or opinions and others helping and giving opinions. ZAPs come from this interaction; those who help receive ZAPs and those who receive help make ZAPs. Therefore, more ZAPs were made than received, and clearly more people were helped than they helped, which is a good thing because many of their questions were clarified.

2025-01-22 15:57:48 UTC

- reply

Not necessarily. Because I can find a relay that doesn't block me or create my own. And when I update my relay list, whoever follows me will get my ratings from the new relay. In NOSTR there is no reach, because there is no feed algorithm. You only see in your feed what you follow and the client will get the ratings of whoever you follow wherever necessary.

2025-01-22 15:00:34 UTC

- reply

These attacks on X don't have much effect, the community notes are robust enough to get around this. But on NOSTR there is no such attack option. Because if you follow the person you will continue to see them. If a relay blocks you, you can use another one.

2025-01-22 12:19:42 UTC

- reply

I don't know. It's all still new and there is no definitive rule. In decentralized environments, prohibiting is always complex. The important thing is not to give feedback and visibility to people who don't have the same moral principles as you.

2025-01-22 10:29:52 UTC

- reply

It's a community effort. Profiles that are frequently reported will start to be blocked by relays and clients, and other people will see the alert that you have flagged the content as hate speech. But the most important thing is that nothing related to this reported profile will appear to you.

2025-01-22 10:25:38 UTC

- reply

I can't say. But there must certainly be more processing to find the numbers closest to the correct one. But they are certainly not 100% correct.

2025-01-22 09:36:10 UTC

- reply

The numbers in NOSTR are not very relevant and it is very difficult to count them because the information is spread across numerous relays. Searching everything generates a considerable battery and internet cost for the user. And the information generated is of low importance. That is why many customers do not spend much processing on these numbers.

2025-01-22 08:36:34 UTC

- reply

The power of the community. Spam alerts are used by relays to block access to offenders. Another important point is that in most clients, only the notes of those you follow are displayed in the feed. If you look at the global feed, you will see a little bit of span.

2025-01-21 22:44:30 UTC

- reply

"request count" is probably the number of times the link was accessed. Probably how many times the link was accessed by an application to put it in the feed. The term "unique views" is the number of real people who saw it. For example, I can open the link 10 times, which would be 10 requests and one unique view.

See the link. It has all the existing relays. You can see their features, technologies used and how to install them. -- Suggestion: If you have knowledge of how to configure a server, do not use Umbrel or Star9. They are heavy and will lose performance. If it is just a test to understand the technology, then it is valid to use them.

2025-01-20 09:22:12 UTC

Many new users are joining NOSTR. And the topic of influencers, likes, and subscribers comes up again. It's always a question for those who are new to NOSTR about this, since centralized social networks are based on these parameters.
In my opinion, NOSTR is not geared towards influencers, advertising, and content creators. It is geared towards interaction between people and mutual help. There will be no ads, so there will be no revenue sharing with content creators. The form of remuneration is zaps, and the incentive to zap content created by someone is if that content is useful or helped the person in some way.
With that, I can only imagine remuneration for content creators through the provision of a service. Where the service is the creation of content for learning or entertainment of the target audience and charging for access to the content, like YouTube members, for example.
I raise this issue because we need to start thinking about applications and features with this objective. NOSTR will only become big if it is financially viable.

You will pay a high price for no reason. There are cheaper and better options. With Bitcoin, you don't need performance; any old computer will do. Lightning nodes require more performance. If you are going to use Umbrella and LND, you need a lot of power.

Liquidation usually occurs when your trade has suffered a large loss. Between 50% and 30% of your collateral defined by the Exchange used.
When this happens, the Exchange sells its collateral to cover the loss and close the trade. The trader keeps the remaining balance.
This only happens in leveraged trades where the trader borrows money from the Exchange to trade.

2025-01-13 23:05:20 UTC

An event can only have one kind. Normally, differentiation is made by kind to facilitate filtering in the relay or client. Imagine if you wanted to create a client only for videos and everything was kind 1. It would be much more complicated to know which events would have a video to display.

2025-01-12 12:14:35 UTC

- reply

If you look at these blocks, they are usually discovered very shortly after the previous block. This means that the miner had not yet selected the transactions and verified them. Until they do this, to avoid wasting processing time on their equipment, they try to mine empty blocks and sometimes get lucky. If it was a block much later than the previous one, then it is just a miner who is doing his job poorly.

This is a feature that the customer needs to implement. I don't see the need for a PIN. But notifications are a bit complex, as they require customers to be connected and receive notifications from numerous relays 24/7. The data consumption of cell phones will harm the battery.

The important thing for me is not hyperbitcoinization but saving as many people as possible before the current economy and states crash.

2025-01-10 20:26:48 UTC

- reply

I really want to be optimistic. But I don't think hyperbitcoinization will happen through this method. It is important and I admire everyone's actions. But hyperbitcoinization will only happen after adoption by multiple states. After decades of not having to deal with real money and save, people no longer know how to manage their assets. Most people will not understand BTC and still think that Fiat currencies are backed by gold.
