1  Bitcoin / Development & Technical Discussion / True Random for automatic offline address generator on: October 12, 2021, 03:31:33 PM
For a BTC related project I need to create some addresses on automatic mode; the machine is offline, the machine prints both WiF Key and matching Address, there's minimal interaction for this, so it won't be able to pick much from its own memory in order to generate a good Random seed.
So my idea came about building a small piece of hardware using RDA5807M FM radio module under follow scheme:

Arduino/ESP(32/8266) --> gets/generates pseudo random between 880 ~ 1080, then divides by 10 -> i2c frequency set -> listen 1 second -> 2x 16 bit ADC (capture stereo output) -> sets bytes accordingly ---> repeat the process
At access: return x bytes stored, where x = amount of seed bytes.
RDA5807M is meant to be equipped with a weak or no antenna, in order to get not only music or whatever is being said at that frequency, but also get noise and interference.
A secondary pseudo random may set it to shift the frequency (+0.05 Mhz) or not.

Do you think this solution would provide a good enough Random generator? If not, what/how do you think this can be improved?
2  Bitcoin / Project Development / Heritage/Insurance Encapsuled Encryption System on: December 09, 2020, 06:02:20 PM
One thing that bothers everyone that has cryptoassets is on how to leave them once we die or if some accident happens that leaves us unable to respond. This can be handy too if we suffer from memory loss.
So I came up with this idea, a set of questions posed to several people, where each answer is the key to another AES encrypted layer.

Let's say you want to put your questions to Paul, Sue and John in a set of 3 questions each. The system will start by asking Paul one question, then Sue, then John, then Paul again, Sue, John, Paul, Sue, John. There's no way one can answer his 3 questions without the other two answer their questions too. Paul won't be able to see his questions if Sue and John doesn't answer first, nor Sue if John and Paul don't answer in between, and won't even be able to know what questions are those...

The system is purely JS and HTML. And I'm sorry if it's a bit sketchy, just got this idea a couple of days ago.

Code:
WHAT IT DOES?

This system encrypts a message under several layers of AES encryption.
The ideia is that you be able to leave a message in case of your death or any accident that leaves you unable to respond that can be opened only by a group of persons you know by answering a set of questions you made.

TIPS:

The system has two vectors, informatics and human. The informatics vector is covered under a well known strong encryption algorithm (Advanced Encryption Standard), in CBC mode with PKCS7 padding.
For the human vector, you should select well the persons and the questions, try to not be too obvious, like "what's your favorite color?", or provide questions whose answers could be easily guess by other participants.
Try to be personal, ask things those persons wouldn't tell anyone over any casual chat, and things that you know only you and that person could possibly know, like "When we first met?", "Where we first kiss/make love?", etc.
You can also use a third party you trust, and unrelated to the question targets, to keep the message safe.

In combination, if you want to leave many data, you can strongly encrypt a True/VeroCrypt partition or file container and leave its password as message here.

This system REQUIRES NO INTERNET CONNECTION. For safety you should do it OFFLINE.


INSTRUCTIONS:

Open the Maker module (maker.html) with your browser (the system was made and tested using Firefox 83.0 for 64 bit Linux) and fill the form, some fields are dynamical and will appear only after other actions are done.
You must set:
- A welcome message, that will display in the header of the Viewer Module.
- A message to encrypt
- A final question and its answer (will be used as password to AES encrypt the message itself)
- The number of people you want to be answering your questions, and their names.
- The number of questions to pose each of those persons.

Once done, press the Generate Code button, it will provide you a file to download named msg.js - download it to the same folder of the "Viewer Module".

To use it:

Open the Message.html file, once the msg.js is in that same folder, at the Viewer module and start to roll the questions.


THIRD PARTY SOFTWARE USED:

CryptoJS v3.1.2
jQuery v3.5.1

3  Economy / Speculation / The pantograph movement on: December 07, 2018, 05:41:53 PM
This is just a curiosity, which may mean something or nothing, but have you noticed the pantograph movement in the 1 year range?
It appears that Bitcoin is moving down on the same fashion it went up last year on the same date, as if a group made 1 year investment and is now leaving (at high loss):

4  Other / Politics & Society / Tolerance & Abuse - Beyond Liberalism on: November 11, 2018, 10:02:52 AM
Tolerance is the pillar of a liberal society, but it has been lately being abused, putting in danger this very same pillar.

Let's start to understand that tolerate doesn't mean to like something, tolerate means to allow others to do things their way even if you don't like it.

A fair example of this abuse lately are the so called "gay rights". WTF are "gay rights"?! I take a c*** up the a** so I want special rights for it?! Get real! What's next? A special parking lot for gay people? A gay soccer league? oh! Wait!...
Oddities can be tolerated, you and your boyfriend like to dress like women and chase each other around the house? Great... do it! But don't force the society to play along. And no you're not "gender fluid" or any other idiotic thing, you're just a guy or a girl, regardless. Deal with it!

So to a point, this issue - and many - are no longer on the tolerance realm, instead they're trying to shove oddities down society throat and demand society to like it instead of tolerate it.
This puts a danger on liberalism, as more and more people starts to react to be getting oddities shoved down their throat and when it turns around liberalism will be taken the blame.
5  Other / Politics & Society / In search of Fascism on: November 01, 2018, 12:51:53 PM
For ages "Fascism" has been used as pure insult, this attitude deprived it from meaning as calling one Fascist or SoB resumes to the same, doesn't exactly means he is indeed a fascist or his mother is a prostitute. Madeleine Albright lately wrote on this subject over the very same concern.

What IS Fascism on strict sense?

From the little Mussolini left behind him, we can establish that any ideology who wants to centralize full power at the State is a Fascist ideology, but little more can be establish beyond the burden of doubt to be or not fascist behavior or ideology, as we start to collide with other ideologies, such as communism, which, by such narrow definition, are fascists, or even worse extreme fascists, as the state controls absolutely everything on society.

So... how can we define and give it a meaning?

8  Economy / Economics / The intrinsic fallacy on: February 07, 2018, 04:37:22 PM
There's nothing more annoying than keep listening to some idiots, and idiots that are supposed to know what they are talking about, speaking about "intrinsic value".
Let's put this straight once and for all:

There's no such thing as intrinsic value!

Intrinsic means something a thing has on its own, regardless of human intervention. What things have is intrinsic properties; gold has the intrinsic property of resisting erosion, copper has the intrinsic property of conduct electricity, and so on. But none has value on its own.

Value is always attributed, never intrinsic!
9  Economy / Speculation / A new perspective, the USD/BTC pair on: February 04, 2018, 03:18:40 AM
Most of people still thinks by what they are more used to, an European will say the Euro worth 1.20 USD whereas an American will say the USD worth 0.8 EUR.
So most people just does the same for BTC, they think on how much fiat a BTC worth but never care to check the opposite: how much BTC the fiat worth. And here things get interesting. You see that huge climb at December to 20k? If you see it on the opposite site it just looks like a flat line.
At the moment everybody keeps saying BTC worth 9000 something USD, but nobody sees it means each USD worth ~0.0001 BTC

Here's a peek at the other side of the mirror:

10  Economy / Economics / The USDT problem on: January 22, 2018, 06:10:12 PM
USDT is leaving some people unrest.
At a glance, it's basically fiat without a trustworthy counterpart, "magic money" at will.
What's your view on this subject and what consequences may be expected?
11  Local / Portugal / O ano dos hard forks on: December 27, 2017, 10:25:01 AM
Ultimamente, desde a Bitcoin Cash, temos tido uma autêntica avalanche de hard forks. Para mim são porreiras para testar algum código mais arriscado que não iria tentar na Bitcoin, e como tal tenho andado a explorar esta nova tendência, aqui fica o que tenho a dizer sobre elas:

Bitcoin Cash: a única que vale alguma coisa.
Bitcoin Gold: vale alguma coisita, tem alguns bugs de código mas é usável e muito rápida a confirmar.
Super Bitcoin: compilei o código ontem, mas parece porreirita para testar.

A evitar:
Bitcoin Hot: só têm os binários já compilados. Podem ficar com eles...
Bitcoin Diamond: moedas do 007 só se for em filme, github vazio, código fechado.
Bitcoin X: não tem releases, mas o site é muito "phishy".

Nada, por enquanto:
Bitcoin Platinum: o cliente compilou mas não se conecta a nenhum peer.

Por ver:
UnitedBitcoin

Anunciadas a sair brevemente:
Bitcoin Cash Plus
Bitcoin God
Bitcoin Uranium
Lightning Bitcoin
Bitcoin Interest
Bitcoin Lite

Não, não é publicidade, é um site que existia para aí em 2009/10 da malta que se dedicava a PTCs e PPVs e onde anunciei pela primeira vez a minha "descoberta" à comunidade tuga: A Bitcoin!
Haverá por aqui alguém que tenha vindo desses tempos?
13  Bitcoin / Development & Technical Discussion / Hostnames instead of IP Addresses on: May 29, 2010, 04:38:52 AM
At least the Windows client seams unable to resolve hostnames - or doesn't even try, pops up an "Invalid Address" right away.

This is a huge setback taken most people have dynamic IP Addresses. Therefore, instead of "123.123.123.123" only it should be added the hability to send also to "someone-accepting-bitcoins.somedomain.sometld".
14  Economy / Marketplace / BitCoin Casino (Beta mode) on: May 26, 2010, 05:44:40 AM
Hi,

I'd been introduced to BC a while ago and found it quite interesting.

Today I just started to setup a casino adapted to BitCoins, you can visit it here: www.sirarthur.net/bitcasino

It's an adaption, removing all Credit Card, wire transfers and so. "Play for real" means to play for BCs, not USD/EUR or any other kind of currency.
Registering was also simplified to a simple: User/Pass (try to not forget it, taken there's no email registered it would be quite... hard... to recover it).

For now I set the minimum/maximum withdraws and deposits on 1 to 1000 BC

Hope you enjoy.

Update: Done the basic debug and featuring of games and casino. You may now enjoy it and, please, report any bugs you may find just in case.  Smiley
Now, for the next 10 to read this and register or have an account in the casino, you can redem the cupon code BITCOINS for 10 BC (cupon will auto-expire afterwards, so be fast)
