1  Bitcoin / Development & Technical Discussion / Re: Why the fuck did Satoshi implement the 1 MB blocksize limit? on: January 26, 2018, 09:03:56 PM
Most probably, it was with this in mind that Satoshi introduced his 1 MB block size.  When he introduced it, 1 MB was way larger than any reasonable block at that time, so it was a good "miner directive" to say that blocks larger than 1 MB should be considered as spam (given we measured blocks in KB at that time).  It was a "good miners' directive" not a "protocol standard".  The idea was most probably, in Satoshi's mind, to give a clear rule to the miners as what was to be considered "prohibitive spamming".  It could systematically be put a factor of 100 or so above the "usual block size".   It was a trivial formalization of the good practice "don't accept obvious spam in the consensus decision".

That's the soft limit... which could be set as a parameter, like 250k, 750k, etc... the 1mb was a consensus rule - and obviously he told garzik that this would make him incompatible with the network if he changed it => https://bitcointalk.org/index.php?topic=1347.msg15139#msg15139

You're right.  Satoshi is very unclear here.  This is food for conspiracy theory  Grin  He's obviously hiding an agenda here.  It simply doesn't make sense and in complete contradiction to what he said before.  This could mean that "Satoshi" was different people, with different opinions.

Without knowing, I repeated cavenden's argument against such a limit.   Re-reading this thread, I think Satoshi had a hidden agenda, and was lying through his teeth here.  He put in a time bomb, that's clear to me now.  And some saw it immediately, but the "Great God Satoshi" was not to be contradicted if you read the priests.

I remember having read that thread, but in my memory, it was like Satoshi said it could be changed and was no big deal, while others told him it was recipe for disaster.  But now I read it again, it's obvious: he clearly knows this, that it is recipe for disaster.  Maybe the Satoshi of November 2008 is not the same person as the satoshi here...

"Don't use this patch, it'll make you incompatible with the network, to your own detriment."

It would be meaningless.  Clearly, Satoshi is dead afraid that his bomb would be removed.  Of course this is bullshit because jgarzik would, in practice, never mine a block above 1 MB.  So he wouldn't be "to his own detriment", be "incompatible with the network" most of the time.


very short answer... because it is cool to see those spikes

Since people need to prove, they are alive, this system will only be possible with a trusted third party to confirm without a doubt, that this DNA belongs to this very person, which always conflicts with point "3) decentralized , without a certifier authority"
There is no way out of this.

The rest is easy to achieve.

Hal Finney managed to mine a hundred thousand coins in a span of three months using his laptop as was stated on his blogs and whatnot. That would give you a thousand coins mined per day using only your weak laptop. In today's rate, that amount of power would never amount you to anything and you'll most likely burn your laptop in the process. You can still mine though, and looking back with full of regrets won't help you get any money. Get some decent GPUs, mine some coins, then trade to bitcoin.

My first bits (pre asic age) was mined using a second hand
something like AMD probook with 2 gpu on it
... that machinery computer is fully disassembled now, I only kept the HD for proper disposal ...
I have no idea where the mind Satoshi are nowdays ...probably it went to a blackhole  Tongue

 Roll Eyes This post let me thinking about ...


A trapdoor one-way function is a special type of one-way function, one with a secret trapdoor. It is
easy to compute in one direction and hard to compute in the other direction. But, if you know the
secret, you can easily compute the function in the other direction. That is, it is easy to compute f(x)
given x, and hard to compute x given f(x). However, there is some secret information, y, such that
given f(x) and y it is easy to compute x.
Taking a watch apart is a good example of a trap-door one-way function. It is easy to disassemble a
watch into hundreds of minuscule pieces. It is very difficult to put those tiny pieces back together
into a working watch. However, with the secret information—the assembly instructions of the
watch—it is much easier to put the watch back together.

As far as I concern, SHA-2, does not have trapdoor ... BUT ....

<2> Regards to Bech32 I am trying to compile it on Visual Studio 2017 community edition using c +1+(https://i.imgur.com/yo5J4Q6.jpg jargon ... hang on (I am running out time) going to ed; this post again ... So I am not sure if it going to compile or not ...since there are some barvarian char set and maybe I only will see the out put at Oktoberfest. (pls relax this is a joke, when we'serious we ARE serious)

I think that this should probably work, mostly.  For its “user interface”, the utility uses POSIX getopt(3) functionality, and also the BSD-style <err.h> (also available on Linux).  I don’t know to deal with that on Windows.  Otherwise, it is just STDC.

I myself can’t test MSVC compilation; for I have no Windows in my house.  Please let me know what results you get.

Should there be indicators of demand, I may try to produce Windows binaries with mingw. 

If you need to replace anything with code from WIN32, I strongly suggest that you #define WIN32_LEAN_AND_MEAN.  I seem to vaguely also remember some define for Unicode, but I don’t remember what it is.  If somebody comes up with Windows/MSVC compat code, I may try to abstract that into a separate file.  I will not clutter main files with #ifdefed Windows code, or Windows “decorations”; I was recently trying to audit a simple cross-platform library where every function is “decorated” with DLLEXPORT, and that junk makes code unreadable.


Thanks nullius,

Definitely I will try MSVC compilation and I will let you know the results I get. But, ( as my usual academic methodology ) firstly, I need to do a research on system development history. For instance, I know that  
Microsoft POSIX subsystem
is old as Windows NT Kernel (  ). ( I don't know, in my memory Microsoft's Unix reminds me
Xenix
. Also regards to cryptology and Redmond campus... in general I find a pleasure reading Niels Ferguson, Bruce, and Kohno book ISBN: 978-0470474242

14  Bitcoin / Development & Technical Discussion / Re: easyseed(1) secure, multilanguage BIP 39 mnemonic seed phrase generator on: January 04, 2018, 10:45:45 AM
To celebrate the New Year, I have the gift of a hidden unstable, unsupported feature for you .onion-lovers.  Here is the address of Wikileaks (http://wlupld3ptjvsgwqw.onion/) encoded as an 8-word mnemonic phrase in 8 languages or writing systems:

Englishreal element glow tennis pluck museum hair shuffle
Chinese (Simplified)洁 爱 唱 仰 泪 吴 乎 怒
Chinese (Traditional)潔 愛 唱 仰 淚 吳 乎 怒
Frenchparole distance fautif sombre notoire loyal flairer ratisser
Italianretina erba idillio suonare potassio opposto india scuderia
Japaneseにもつ けろけろ しちりん ほめる とかす たんまつ しゃうん はんしゃ
Korean잠자리 반죽 상품 큰딸 이불 열차 선풍기 중반
Spanishpie dulce gimnasio tabla oscuro molde guerra repetir

What's the purpose of this feature? It seems (superficially) that there's no real-world use case.

Why, what’s the real-world use case of BIP 39<1>?  To ease human memorization, transcription, and communication of pseudorandom strings!

Bitcoin has been a leading innovator in the development of better ways for humans to interact with cryptographic gibberish.  With BIP 39 mnemonics, a mere mortal human can memorize a pseudorandom string, write it into a sealed Last Will and Testament in a manner easy to transcribe back into a computer—or if necessary, whisper it into somebody’s ear...

I should think that people may want to memorize, transcribe, speak, or whisper .onion addresses, too.

As an English speaker, which would you prefer to deal with in your capacity as not being carved out of silicon:  “wlupld3ptjvsgwqw” (ouch!), or “real element glow tennis pluck museum hair shuffle”?  Chinese people may prefer “潔 愛 唱 仰 淚 吳 乎 怒”.

For overlapping reasons, I have also been working on the application of BIP 173 Bech32 encoding for .onion address data (more).  That has the advantage of error correction, and a more compact format; different tools apply to distinct use cases.  Again, Bitcoin technical innovation opens new possibilities in other applications of cryptography.

I am also using these methods with PGP.  I’ve seen PGP mnemonics before, of course—but the mnemonic standard I recollect having seen many years ago used a 256-word (8-bit) alphabet<2>, rather than the 2048-word (11-bit) alphabets from BIP 39.  Thus, unnecessarily long word strings.  I am also working on a spec for what I call Bech32 “PGP Descriptors” to encode key fingerprint plus metadata.  See those ugly hexadecimal strings in my signature?  Bitcoin will provide a better way.

Meanwhile, for use in Bitcoin, I have almost completed full BIP 39 implementation in easyseed(1).  It would have been done yesterday; but for the missing final piece, generation of the output seed, I need means to perform the specified Unicode NFKD normalization without dragging in ugly dependencies.  The rest is trivial.

<1> It remeber me vaguely on some debate while the implementation of UTF-8 ( Ken Thompson and Rob Pike ) maybe there are some valuable lessons in computing history to remember...

15  Bitcoin / Development & Technical Discussion / Re: bech32(1) for encoding/decoding of Bech32 strings & “Bravo Charlie” Addresses on: December 30, 2017, 10:17:09 PM
I have released an initial version of the bech32(1) utility for encoding and decoding of BIP 173 Bech32 strings and Bitcoin “Bravo Charlie Addresses” (“bc1”).  As any worthwhile software, it comes replete with a manpage (text), q.v.

As part of its initial feature set, bech32(1) has special handling for RFC 7686 .onion special-use domain names; it detects such a name, and transcodes the RFC 4648 Base32 to and from Bech32 with an HRP of “onion”.  For Bitcoin “Bravo Charlie” addresses, bech32(1) takes and gives the witness version and the hexadecimal-coded octets of the witness program.  Otherwise, for the most part, it encodes and decodes hexadecimal data with user-provided HRPs.  I intend to add special interpretation of “pgp1” with a concept I call “PGP Descriptors”; but I need to spec that out first.

Some usage examples from the manpage:

Code:
Extract the witness version and Hash160 from the bech32 utility author's
Bech32 tip address:

      bech32 -S bc1qcash96s5jqppzsp8hy8swkggf7f6agex98an7h
      0:0xc76172ea149002114027b90f0759084f93aea326

Get a “hello, world” introduction to Bech32:

      bech32 -e -h hello_world 48656c6c6f2c20776f726c6421
      hello_world1fpjkcmr09ss8wmmjd3jzzwhs4ff

Generate a “burn address” with a Hash160 of all zeroes, which would be
spendable by the same unknown private keys as the infamous
1111111111111111111114oLvT2.  Warning:  Do NOT send coins here:

      bech32 -s 0 0x0000000000000000000000000000000000000000
      bc1qqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqq9e75rs

Bech32-encode the address for Wikileaks, to add error-correcting codes:

      bech32 -e wlupld3ptjvsgwqw.onion
      onion1kt50trm0nf4jxkskpcjy74

Now, decode the address someone gave you:

      bech32 -d onion1kt50trm0nf4jxkskpcjy74
      wlupld3ptjvsgwqw.onion

Licensing includes a Bitcoin Consensus Clause, to prevent use by scamcoin pretenders.

This is an alpha-quality initial release.  The code is still a bit messy; it needs test vectors, which seem insufficiently specified; features and the finer details of behaviour may be a bit in flux.  However, the basic user interface should be considered stable.  I am here opening a Bitcoin Forum thread for discussion of this utility; over time, I will edit and update this post as appropriate.

What do you think to the bitcoin prices in 2018? It will continue increasing up or continue declining down?

If increasing up, what value do you expect? Same if it is declining down?

I think since we're entering on main stream financial system ( such as CME Group, etc ) we going to see more debate on privacy, money laundering regulations, etc

Criminals use banks as well
Machon conceded that criminals would inevitably use Bitcoin and other cryptocurrencies - but that doesn’t stop them from using banks either. Using that is an easy excuse to infringe on people's privacy, according to the former MI5 official:
“Any crackdown on our rights of privacy on the internet always has an excuse that it is trying to stop money laundering or trying to stop terrorism or pedophiles or whatever. I think, probably the vast majority of users of Bitcoin are doing it legitimately, they just have a legitimate concern to uphold their right to privacy as well.”

These multisig tx can come from everywhere.... Everyone is free to create such a tx.....
...The idea behind a multisig transaction is, that you use two or more signatures, to make the transaction valid.
You can compare this to a cheque payment, which needs to have two (or more) signatures to be accepted by your bank....

The journey of bitcoin from 2009 to 2017 is very interesting. Although the stories of individuals(investors) are very interesting and motivational that how they initiated and what problems they faced at earlier stages.

In 2017 the number of businesses accepting bitcoin continues to increase. Where you see the bitcoin in 2018?

it was indeed ... well I would bet on institutional investors paying more and more attention to bitcoin community's voice
