There is no way to avoid it. This is public information. What can mitigate this is the use of clients that implement outbox and relays that require authentication. This can also protect your private notes from being seen by you alone. But if you have placed them on a public relay, there is nothing you can do.

Wouldn't it be a better approach to filter at the time of the search? Only return the most recent of the replaceable notes?

Some clients only show a list of relays with read and write options. Amethyst organizes it differently. Many clients don't support it.

I found it strange that the text was just quotes, it's hard to tell what's your opinion and what's someone else's speech. I think there was something wrong with the formatting. I read the text on Amethyst and habla news

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.

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

- 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.

2025-01-30 07:43:50

- reply

Just out of curiosity. Why do you want a relay for you and your guests? To talk about things between you without it becoming public? I'm developing a relay and this use case made me curious.

There are many ecosystem projects here, you may find something interesting to contribute.

There are areas in NOSTR that are simple, some basic internet concepts are enough. Other parts are quite complex. I suggest reading the NIPs and following the discussions on Github. You don't need to help with the protocol specifically to help the ecosystem, you can help with some existing application project.

2025-01-29 14:46:11

- reply

This happens because Amethyst did not receive the confirmation response of the ZAP payment. I have the coinos.io wallet and this happens when I add the coinos.io relay. Something happens in the communication and the messages do not reach those who are waiting.

2025-01-25 17:55:54

- reply

NOSTR needs to guarantee data delivery. And implementing this in UDP will be more cumbersome than TCP itself. UDP is for data that does not need to be guaranteed to be delivered. For real-time data, UDP is useful because if a packet is lost, the next one will arrive.

2025-01-25 17:24:35

- reply

But in theory this shouldn't be a concern for a common user. The applications should manage this automatically. But it's still a process of evolution in the applications. I know that Amethyst does some of this management, I don't know the others in this detail.

The private relay is a relay that only you have access to, it would be a backup. If you want a note to be seen by a large number of people, it is better to put it in public relays.

2025-01-25 16:38:40

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

- 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.

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.

NOSTR was created to be against censorship, the burden of this is not being able to ban the most elements. It is up to each person not to just give voice to what they think is wrong. Fighting, reporting and demanding measures is also valid.

2025-01-22 15:00:34

- 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 10:25:38

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.

2025-01-21 22:44:30

"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.

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.

If they are children over 15 years old, I don't see any problem. They should already be prepared to face the dark side of the world.
I don't recommend it for minors, as there is no way to control and monitor what children have access to. There is still no client with parental controls. I don't think it would be difficult to implement, as it would just show the feed only to those who follow you and ask for parental approval to follow someone.

The cracking won't happen overnight. It will be gradual as weaker algorithms are cracked, and Bitcoin will probably be upgraded to something more secure. We'll start seeing studies and tests released before anyone actually manages to crack BTC keys. Bank passwords will be cracked first.

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.

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.

The Lightning Network has a sending fee. However, the fee depends on the route, and is usually very low and is calculated in msat (1 thousandth of a sat). However, it is common for there to be fixed fees that can reach 1 Sat.

- reply

If you are looking at the same model from different generations, it doesn't make sense that it would be slower. But I suspect that you are looking at different models. All generations have cheap CPUs and high-performance CPUs. A cheap CPU from a recent generation will be slower than an old high-performance CPU. Models numbered 500 or less are cheap CPUs. Above 500 are high-performance. The 900s are the most powerful.

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.

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.

That's exactly it. The base is dollars and only converts to sats. The conversion can be done at the time of sale or periodically to simplify the process. One day if BTC takes the place of the dollar as the global currency, then we can use the value in sats as the base.
