Buenas, yo personalmente prefiero publicar en Ingles ya que creo que asi tengo un poco mas de visibilidad, asi mismo me gusta leer mas la seccion en ingles ya que por lo general tiene temas mas variados y temas tecnicos con mayor participacion de usuarios veteranos (Por ejemplo no me imagino a Loyce publicando en esañol ).

He visto que @DdmrDdmr intenta replicar mucho de lo que se publica en ingles en el foro local y eso esta muy bien.

Acabo de contestar una de las encuentas y esta fue mi respuesta rotunda: No hay suficiente discusión técnica en nuestro foro local

Comenzare a publicar mas temas en el foro local, voy a traer algunos de los temas que tengo publicados en ingles aqui.

Creating a sub-board dedicated to Cybersecurity in a Bitcoin community is a topic that warrants careful consideration. As a Global Moderator in a Spanish Hacking forum I can tell you that you are right that kind of sub-boards are filled with a lot of noobs, script kiddies and scammers.

A sub-board focused on Cybersecurity can provide valuable educational content for community members. It can help users understand the risks associated with Bitcoin and cryptocurrency and equip them with knowledge on how to protect their assets.

By offering discussions on vulnerabilities and hacking techniques, the sub-board can raise awareness about potential threats. This can empower users to take proactive steps to secure their investments and personal information.

AFAIK the equilibrium of the AIR in our atmosphere nitrogen and oxygen is very importan to preserve the weather and life in this plannet. When methane is released into the atmosphere, it can absorb and trap heat from the sun, contributing to the greenhouse effect and global warming. This can lead to various consequences

In the case of my keyhunt tool you can select a specific range, so, if in you code you can do the same the idea should select the same range and check how many coincidences it found and how much time it takes.

Another way to make these benchmarks is just put them at random ranges and stop them after some 15 minutes or half an hour and compare how many addresses they found, this may not be fair or may be biased because Address prefixes are random and it's not predictable how often they may appear.

Well i think that actually SecureRandom must be enough validated by the community, some of us may remember some nasty bug in  SecureRandom that lead in some multiple bitcoin wallet hacks

Weaknesses in Java SecureRandom (e.g. Android bitcoin wallets)
Some SecureRandom Thoughts

If you aren't sure of using SecureRandom, I may suggest o try to use the RNG of the Guests OS, but that may complicate the code a little and also make it OS depend, that break the the Java Parading: Write once Run Anywhere

I like the OS Random Number Generators, but for Java I recomend stick on the Standar Class.

SecureRandom

if you want to do some benchmarking try to compare it againts the:

VanitySearch
Keyhunt vanity-search

well, i am only going to point to the opportunity Cost, Governments and often have competing priorities, such as investing in infrastructure, healthcare, education, and social programs. Paying off debt immediately would require diverting funds from these essential areas.

Yes I agree with you those just were some vague thougts.

Also i know that we don't need to read the paper to adopt bitcoin, but it is very interesting to read in any case (I strongly recomment read it)

Something that bothers me is the white paper has the website in the header.



It says clearly www.bitcoin.org

How the F. a stupid judge can ignore that?

Voy a intentar publicar algo al respecto de este tema, pero me llevara algo de tiempo (tengo que esperar a que baje un poco el fee) y muchos utxos para poder hacer realizar las pruebas pertinentes.

Saludos!

if you have some doubts with  bitcoin technical stuff don't doubt in reach me, i can point you to the right and trusted sources of informacion.

Regards!

Agree with you it's never too late for it, I am also stacking every satoshi that I can.

I did not move much bitcoin before, my first wallet doesn't have many transactions but it is from 2011, almost 12 years ago, yes we missed the opportunity but there is no way to feel regret of that, it is sad but we can't change anything of that feeling on that way, then IMO is better to look at the future with better expectatives and begin informed about bitcoin and its technical topics will be good for all of us

So, keep stacking those sats and stay curious. The bitcoin game is still young, and who knows what's coming next

We have still 29 halvings to walk for a while

It is a difficult topic, the news is also unbelieve to read. But I think that seeking for karma it's not a good way, i mean if karma would act, it should do that alone no?

One option may be to locate friends or users there and encourage them to distribute the bitcoin wallpaper, but that may also have legal issues against them no?

A way to win this should be made in a technical way, I don't know how, let's ask the real satoshi to sign a text message saying that CSW is a liar… o wait there is a message already signed by old miners no?

Welcome to the forum! It's great to hear about your journey into the world of cryptocurrency. Many of us have had similar experiences of initial skepticism, given the prevalence of fraudulent schemes out there. It's commendable that you took the time to research and educate yourself on the topic through platforms like YouTube and Telegram channels.

I'm glad you decided to join this forum. It's a fantastic place to exchange knowledge, share experiences, and continue learning about cryptocurrency. If you ever have questions or want to discuss specific aspects of crypto, feel free to ask. I'm here to help and learn together!

If there is some recomendation to start learning something is this next link: Chapter 4. Keys, Addresses, Wallets

Rember not your keys not your coins

OP might be a bit mixed up here. When you get money on Binance, they give you an address (an address that bianance control, rember not your keys not your coins). But then, Binance moves that money to another Binance address (Binance Hot wallet). Don't worry, your Binance account should still have that money, even though if you check that address on some explorer, it'll look empty.

At least that may confuse to some new users like him

I've been on Twitter since way back in April 2011, and I've gotta say, I've had a good time there. I love the stuff I find, and it's where I stay updated on what's happening. But the latest news about them thinking of charging a monthly fee has me feeling pretty bummed.

Twitter is like my main squeeze in the social media world. I mean, aside from some forums and Telegram, it's the place I hang out online. I've met friends, laughed at memes, and had some cool conversations.

But here's the thing – if Twitter starts asking for cash to use it, I might have to hit the eject button. I get they need to make money, but it could mess up what's great about Twitter. It's open to everyone, and that's awesome. Charging money might shut some people out, and that's not cool.

So, if they really go through with this fee thing, I'll have some thinking to do. I mean, I love Twitter, but I also love not spending extra money on social media. We'll see how it goes, but I really hope they don't push me to say goodbye to my Twitter crew.

Buenas, no se si abrir otro topic o no, asi que mejor dejo este mensaje por aqui.

Siguiendo el debate sobre la legalidad de los servicios de mixers y quiero aportar un punto de vista que, en mi opinión, merece ser considerado. Se ha hablado mucho sobre cómo estas herramientas pueden ayudar a preservar la privacidad y la seguridad financiera de los usuarios, pero también es importante abordar la posible responsabilidad legal que podría surgir de su uso.

Imaginemos una situación hipotética: un usuario nuevo, como muchos de nosotros en algún momento, decide utilizar un servicio de mixer para proteger su privacidad en la cadena de bloques. Después de la mezcla, este usuario recibe UTXOs que esta direcatmente ligado en mayor o menor medida a cierta activdad ilegal, como lo podria ser un robo o un rescate de ransomware, compraventa de articulos ilegales etc...

La pregunta que quiero plantear es: ¿qué tan responsable sería este usuario si, sin conocimiento previo, utiliza esos UTXOs y los cambia por dinero en efectivo en su exchange favorito?

Desde un punto de vista legal, la respuesta no es tan clara como podríamos pensar. En muchos sistemas legales, la culpabilidad se basa en la intención y el conocimiento del individuo. Si el usuario no tenía conocimiento de que estaba utilizando UTXOs de origen ilegal y no tenía ninguna intención de participar en actividades ilícitas, ¿debería ser considerado responsable o por lo menos facilitador de encubrir un delito? Lo mismo aplica para el Exchange que al final es quien termina Mezclando aun mas ese UTXO en sus hojas de balance y distribuyendo a quien sabe cuantos usuarios mas.

En última instancia, la responsabilidad legal en este escenario puede depender en gran medida de las leyes específicas de cada país y de la capacidad del usuario para demostrar que no tenía conocimiento ni intención de participar en actividades ilegales. Esto nos recuerda la importancia de conocer las leyes y regulaciones financieras locales y de ser conscientes de las transacciones que realizamos en el mundo de las criptomonedas.

¿Qué opinan ustedes?

All those address can be derived from the RMD hash of the address, example:

Address 13zb1hQbWVsc2S7ZTZnP2G4undNNpdh5so decoded in to Hexadecimal is:

0020d45a6a762535700ce9e0b216e31994335db8a5ee6612b2

But first byte for btc address is alway 00 and last 4 bytes are te checksum: ee6612b2

So the Real hash160 of the address 20d45a6a762535700ce9e0b216e31994335db8a5

Example with Dogecoin is almost the same, address D88gYxMEoumtZSJAC9mwa2EWfm6g3uocon

Decodes is 1e20d45a6a762535700ce9e0b216e31994335db8a50d861875

1e is the prefix for Doge, the checksum are the last 4 bytes: 0d861875

So the Real hash160 of the address 20d45a6a762535700ce9e0b216e31994335db8a5

So for almost all altcoin you only need the original rmd160 hash check the next image:



I recommend you to read Chapter 4. Keys, Addresses, Wallets

Hi, nice code The prime numbers approach is a good idea, I also try it some time ago, but it only works as you said if you have the right factors if no then the brute force approach of the prime numbers is also some exhaustive, we can try some small and common factors but those don't provide much speed, but if the prime factors aren't common then the probabilities of some prime number is factor of our key are very low probabilities.

IMHO this prime number approach is a nice as proof of concept but with some low success

That is not quite right, thereis still the option of FullRBF, but yes that depends of the software used to do the transacction.

Bitcoin Core 24.0 Will Enable Full-RBF — The End Of Unconfirmed Transactions?

Example:

I wonder if this kind of actions would bring or open something like a "precedent" for other situations

It is not the first time that a return of this type has been done, but the media coverage that this particular case has captured the attention of the financial, technological and general bitcoin community.

The worry is that if we allow this now, it might lead to more situations like it in the future. Think about a situation where someone comes with arguments like Craig Wright did againts bitcoin developers, saying that miners should be responsible for users losses or helping them to recover their lost wallets...

Just image that. 

My recommendation to miners would be not to return anything to people/corporations they need learn from their mistakes.

Regards!

To be honest i don't think that the first merit is difccult to get, but that depends of each person and the quallity of the topics that the publish or then thing that they share.

My get my first merit when i publish a message sharing my open source project, and that was my message number 6, previous 5 messages before it don't get any merit

However, I must emphasize that achieving merit constanly depends on the relevance and value of the topics you engage with or the content you share. It's essential to focus on contributing meaningfully to the forum, and over time, these merits will naturally come your way.
