2521  Bitcoin / Bitcoin Discussion / Re: Bitcoin Core 0.15.0.1 Released on: September 21, 2017, 11:02:52 AM
Will that make creating vanity addresses any easier? (from the computing power perspective)

I think it would, not 100% sure, there may be some mathematical subtleties I'm not aware of. In principle, it should (I think this new Bech32 format is 32-bit in length and using base 36 numbers, whereas the current address format is 33 bit and uses base 58 numbers).


and whats the ETA?

Not sure. The objectives for 0.15.1 aren't outlined AFAIK, it's possible there are other changes that could usefully be included. 8-12 weeks, if I were to guess.
2522  Bitcoin / Press / Re: [2017-09-20] Segwit2X: the broken agreement on: September 21, 2017, 10:48:21 AM
I have nothing against the "Segwit2x" proposal as such (for me, 4-5 MB blocks, like it can be estimated if the proposal becomes true, would still be OK in a big network like Bitcoin

Thx d5000 for you last sentence here, because I - speaking for big blockers - would be happy if there will be a better consensus for HF if it could be shifted a bit into early 2018 - but core needs to signal this first - or Novembers NYA will come.

You two are only highlighting how disingenuous the "big blocks" position really is.


You've got your big blocks Bitcoin, it's called Bitcoin Cash, but you don't want it for..... some reason?


So, why don't you tell the world, honestly, what it is you really want, because if it was big blocks, you shouldn't actually be on the forum of the conservative blocks coin. At all.

So why are you still here?
2523  Bitcoin / Bitcoin Discussion / Re: Bitcoin Core 0.15.0.1 Released on: September 21, 2017, 10:29:37 AM
Which version is going to have full SegWit support? 0.15.1?

Segwit wallets plus a native address format (i.e. not script nested P2SH addresses) in 0.15.1. The new format is going to be cool, there will be no more case sensitivity in the address (i.e. bethisabitcoinaddressinnewbech32format is the same address as BETHISABITCOINADDRESSINNEWBECH32FORMAT)
2524  Bitcoin / Development & Technical Discussion / Re: If Core had to hard fork and use another mining algorithm, what would it be? on: September 20, 2017, 12:36:16 PM
I believe the thread was hijacked by the Segwit2x vs. Core topic. They are still good to read though, but please answer my original question first.

IF Core decided that a Proof of Work change is needed, what kind of mining algorithm will they use in your opinion? Will they develop something new, or will they use something that is used now like Scrypt?

There is also a new white paper for another mining algorithm out there called Proof of Space. https://www.coindesk.com/proof-of-space-bittorrent-creator-publishes-eco-friendly-mining-paper/

And certainly a lot of new mining algos I've now seen - eco-friendlier, asic-resistant, etc. While I doubt the snazzier ones like Proof-of-Time are technically solid, I do like some aspects of Proof-of-Importance... amount of work important, but so is quality. Amount of coins important, but less than usage, for example.


A vaunted algo was something called EquiHash (I think), as it's design is amongst the more difficult to produce an ASIC circuit for, and presumably it isn't too new or based on exotic math. But it will always be possible to produce an ASIC eventually, Scrypt was always touted as "ASIC resistant", until someone produced an ASIC unit with the requisite RAM modules to vastly outcompete PC/GPU Scrypt miners.



The key will clearly be to alternate hashing algorithms for PoW, either individually, or as a series of hash functions with the order of the series alternated randomly from a large set of hashing algos (Meni Rosenfeld's idea). And while that would decentralise mining a great deal, it would still mean those with access to the most resources would dominate mining (i.e. money, access to large premises with suitable MW rated electricity supply, cheap electricity, suitable environment for cooling, political favour etc).

But small miners would suddenly get back into the game even still; right now, mining ASIC manufacturers deliberately set the price of complete miner units at a level that guarantees their continued dominance in the actual block reward market (something like 5-8 times the market price of what electronics of a similar level of sophistication and material constituency typically would be). With that huge economic disadvantage removed, home miners can of course purchase regular CPU or GPU computing devices at the same prices as large organisations can. It would be good for Bitcoin, despite being somewhat disruptive at first.
2525  Bitcoin / Development & Technical Discussion / Re: If Core had to hard fork and use another mining algorithm, what would it be? on: September 19, 2017, 09:36:14 PM
Any coin that "regularly changed it's algo" would be cutting it's OWN throat - users are NOT going to tolerate the disruption of having their coins become UNAVAILABLE on a regular basis due to algo-forced wallet changes and NO MINER HASHRATE TO CONFIRM TRANSACTIONS during these changeovers.

It could be implemented in way that wouldn't involve huge breaks in the hashrate, so I would forget about that angle

 I would NOT forget about it.

 As soon as you change the algorithm, you have most or ALL of your miners suddenly not mining 'till they change the mining software.




Yes, that could be avoided, depending on how it's done. Don't worry, it's fairly simple to achieve.
2526  Bitcoin / Development & Technical Discussion / Re: If Core had to hard fork and use another mining algorithm, what would it be? on: September 19, 2017, 07:21:06 PM
Yeah, because super-majority miner activated hard-forks away from the proven development team, with zero technical justification == letting people choose


Done with you DooMAD, your shill account is burned
2527  Bitcoin / Development & Technical Discussion / Re: If Core had to hard fork and use another mining algorithm, what would it be? on: September 19, 2017, 06:24:40 PM
If a majority of the hashpower does fork away, I have no qualms whatsoever with a change in mining algorithm.  Quite the opposite, in fact.  The hashrate has to come from somewhere, so CPU miners at home would be perfectly prudent and realistic.  


Hmmm, yet before your opinion was wildly different. You claimed that the chain with most PoW will be, by your own personal decree, called Bitcoin, and any remaining fork of the blockchain would be an altcoin.

Maybe you should stick to your alleged principles, and actually let people choose. And hey, maybe you could offer a qualitative assessment of the choices, instead of painting yourself as some kind of unbiased observer, while actually doing a very subtle job of steering peoples opinions on psychological/subjective matters regarding cryptocurrency hard forks (sorry to inform you, it hasn't worked, no-one much is interested in the rather thinly disguised attempt to take the development reins that you've been tacitly supporting)
2528  Bitcoin / Press / Re: [2017-09-18] What Last Week Tells Us About Bitcoin on: September 19, 2017, 05:42:15 PM
It will also take time for governments and monetary authorities to understand the full array of costs and benefits of this new platform, and to arrive at a consistent regulatory and supervisory approach.

It's an anti-government, pro-individual technology. It's never going to happen, cryptocurrency is now and always will be outside of government regulation and supervision. It's designed like that, deliberately Roll Eyes


For now, the operational dimensions of cryptocurrencies will involve primarily speculative activities, cannibalizing at the margin the investor base for precious metals, and meeting the demand of those looking, both for legal and for illegal reasons, for a payment system that operates outside the view and reach of monetary authorities.

How can these Bloomberg idiots not see the glaring contradiction of the above statement? The whole purpose of cryptocurrencies is to operate outside of the grasp of "monetary authorities" and as such, has succeeded in that task so well that the authority no longer exists.

Cassette recording and peer-to-peer file sharing technology in essence gave everyone in the world copyright to every recording ever made. In the same way, Bitcoin makes everyone a monetary authority. It's gone boys. It vanished, wake the fuck up.


Over the longer term, a more stable and regulated platform will likely emerge. It will supplement but not replace the traditional system managed by central banks.

Someone help these Bloomberg people, I fear for their sanity when the gravity of this situation finally becomes obvious enough that they can't understand what's going on.
2529  Bitcoin / Development & Technical Discussion / Re: If Core had to hard fork and use another mining algorithm, what would it be? on: September 19, 2017, 01:48:28 PM
This is what he said about the possibility of a change in the Proof of Work algorithm.
Quote
In a situation where the majority of miners are supporting SegWit2x and users still prefer the original chain, Maxwell noted that a change to Bitcoin’s proof-of-work algorithm (SHA-256) would “make sense”. The Blockstream CTO does not view SHA-256 as a defining trait of the Bitcoin system, and he noted that it may need to be changed in the future for security reasons anyway.

Changing the proof-of-work algorithm would effectively destroy the investments bitcoin miners have made into specialized hardware used for the mining process. Maxwell referred to this as a “nuclear option”.

It will depend on the Bitcoin community.

And I expect such a move would find very significant support in the Bitcoin community, it's simply not wise to trust the Seg2x developers when they are either unknown or, worse, known to be enthusiastically against the principles of permission-less sound money.

And then it would be true gold rush time, any new hashing algo chosen would be carefully vetted to be sure that the development time/cost for an ASIC would be maximised. A whole new generation of Bitcoin home miners would flourish Smiley

I expect DooMAD to ridicule this and make subtle points steering any readers in the direction of the Segwit2x fork, as usual, but let's remember that he's the only voice on the whole Bitcointalk board even faintly supporting Segwit2x. There's no proven case in favour of the move, and all other information suggests there are several reasons against the November hardfork.

Cue DooMAD, talking about how much he "favours choice", yet refuses to ever acknowledge the value proposition of the supposed choice that's actually being forced on the users (except when people are suggested to choose something that threatens the miner cartel, oh what a strange coincidence Roll Eyes), take it away son
2530  Bitcoin / Press / Re: [2017-09-19] China Cryptocurrency Ban Only Fuels GPU Sales: RBC on: September 19, 2017, 07:40:54 AM
At a first glance, it seems quite expensive, but analyzing the method carefully it could be even more convenient than mining because electricity costs are much lower.


And it's much less obvious to neighours, or your electricity provider, that something unusual is going on.

And hey, home mining in China may just become much more usual anyway if super draconian measures against cryptocurrencies ensue, the Chinese state (or any state for that matter) is only ever really effective at "cutting the heads of flowers that grow too tall". 100's of millions of people in China mining (or using other resources to obtain Bitcoin) are going to be impossible to stamp out effectively, yet again without turning China into a wholesale facsimile of the North Korean state. PRC could kiss their world economic standing goodbye if so.

And if mining were banned, I expect the Chinese market (and those of surrounding states) will be flooded with mining units from the large mines that are shut down, and they'll be sold pretty cheap in order to get the sale done quicker.

And in addition, mining ASICs will still likely be manufactured in China, the Chinese government is only too happy, upto now, to allow very loose control over electronics manufacturing, as they're all too aware that the state is profiting from the copying of copyrighted electronics for years now. It's going to be incredibly difficult for the Chinese state to put the Bitcoin genie back in the bottle, and of course, this was Satoshi's intention when he developed Bitcoin's design.

Is it just me, or is John McAfee not misrepresenting the facts also? I don't think he is a Bitcoin miner, he supposedly (or at least according to him) is on the run from Belizean government assassins? Maybe he changed his story, but this guy is full of questionable stories.

Also, isn't he a part of the whole Bitcoin Cash thing, being close to Bitmain et al? He seems like a spurious defender of Bitcoin, or questionably good example of it's human capital, looked at several different ways.

Losing BitPay would mean we lose pretty much all of the mainstream market unless comparable alternatives are available.

Bitpay is not the only B2C payments processor in the market, nor have I heard it said that Bitpay will refuse to service transactions from the Bitcoin blockchain in the event that Segwit2x forks away from the Bitcoin blockchain.

But it's kind of an interesting aspect of this situation; if Bitpay refuse to take payments from the cryptocurrency with the biggest economy and/or monetary base (as is their present mission statement), then why not? Cheesy Even if Segwit2x displaced Bitcoin in these metrics, it would still be a little strange.

Hmmm. I'll be in southern Africa in a few months.  May have to pay these guys a visit?

Please report on the experience. It'll be interesting to see how many regular people are using it, and some indication of how frequently. I predict it may be a little prone to overall awkwardness, on-chain transactions are a bad fit for this kind of retail experience.
2535  Bitcoin / Press / Re: [2017-09-18] The Pirate Bay is Pirating Your Processor for Bitcoin Mining on: September 18, 2017, 03:24:41 PM
WTF

How stupid are the Cointelegraph writers?


HELLO? Piratebay are already operating on a questionable legal basis, laws regulating mining are going to make precisely zero difference



And this is all without going into the more important point; cryptocurrency mining is intended to be permissionless, it's a very important part of imbuing Bitcoin with permissionless transacting, and HENCE A VERY IMPORTANT PART OF WHAT MAKES BITCOIN VALUABLE AS A CURRENCY TO BEGIN WITH.


Cointelegraph.com; you're off to see the wizard, desperately in search of just one brain that will allow you to provide cryptocurrency journalism with meaningful or intelligent reporting. You may as well employ regular news journalists with no knowledge of this subject if this is what you have to offer.

2536  Bitcoin / Bitcoin Discussion / Re: Bitcoin needs to be worth $1,000,000 to be a legitimate currency on: September 18, 2017, 03:12:12 PM
The italian Lira was worth 1/1936.27th of a Euro, did that make it a non-legitimate currency?

100s of dollars are thousands of Yen, is the Yen a non-legitimate currency?

Value means very little, if dogecoin was more widely accepted than bitcoin, it would be the "better" currency.

Well, the logic this commentator is using suggests the opposite: that currencies worth several orders of magnitude more are less legitimate than their competitors with less purchasing power per unit, i.e the Italian Lira and the Yen are actually more legitimate than the Euro or Dollar, because they're less valued.



Which illustrates an even clearer way to disprove this nonsense; the Japanese Yen and the Italian Lira were both heavily devalued in order to balance the public finances of their respective governments, stealing from the people holding those currencies to (help) pay for managing their fiscal budget so incredibly poorly. I say "help", as the real insult is that the Italian and Japanese never paid back the money they borrowed, they simply paid enough to make the debt load sustainable.

The real purpose of this commentary is to set Bitcoin an impossible task, but this and other commentators should be careful what they wish for. Worldwide economic circumstances could easily prompt Bitcoin to take such a seemingly fantasy valuation, upon which these sorts of commentards will simply change their magic formula for "legitimacy". But once Bitcoin reaches those heights, the writing may already be on the wall for the established financial system regardless of "influential" people hoping to talk reality out of existence. Nothing can stop an idea whose time has come.

Good luck with your continued talking, gentlemen. Is it not the case that talking appears to be all you've got? Seems a bit like that for some time now Cheesy
2537  Bitcoin / Press / Re: [2017-09-18] South Africa’s Second Largest Supermarket Chain Pick n Pay Trials.. on: September 18, 2017, 02:53:20 PM
Not really workable on-chain in the long term, hopefully the POS company involved (Electrum?!) will have the sense to implement Lightning payments sooner rather than later. Small, independent shops is one thing, but large chains of stores cannot tolerate anything but the smoothest POS experience.

Sidenote, surely this is not the same organisation that develops the Electrum wallet software? Thumbs down for confusing the marketplace if not, and sideways thumb for selling the brandname if so. I hope this won't mean bad things for Electrum wallet users in that case (although Electrum Wallet has always had that federated servers aspect that caused my disinterest in using it, maybe it could be good in the end, assuming that's the situation of course).
2538  Bitcoin / Bitcoin Discussion / Re: China just like banning things, Google, Facebook, Twitter, then Bitcoin. on: September 18, 2017, 12:08:20 PM
The future of bitcoin is in the west - western govts like it because they can track payments and therefore collect tax, and if the banks fail AGAIN, they don't need to bail them out this time, just direct people to the bitcoin network instead (an option they didn't have in 2008). That last bit is pretty much the reason why the USA legalised bitcoin.

None of those things are true, though.

  • No government can know the jurisdiction in which a given transaction happens, or if the participants are subject to their tax legislation
  • Governments have no effective tax collection method for cryptocurrency, banks are set up to make tax collection cheap and easy, whereas collecting cryptocurrency as tax would be expensive and ineffective
  • Banks have amongst the largest political power existing, and would strongly resist moves to turn their tables over
  • Governments are heavily composed of people with stakes in the banking industry, and so resistance of the removal of a banking oligopoly is probably unnecessary in any case
  • USA didn't legalise Bitcoin any more than they legalised walking down the street, it's simply not legislated on the basis of it's use
2539  Bitcoin / Development & Technical Discussion / Re: A replacement Alert System should be considered to promote updates as necessary on: September 18, 2017, 11:58:13 AM
Instead, as the oldest cryptocurrency Bitcoin has been developing as the most stable and secure, where even small changes, like scaling issue, is very rigorously discussed.

[snip]

Core celebrates the fact that it is the oldest coin and it respects that through not adding much change over time and instead focusing on improving and rigorously testing the already established features.

[snip]

There are many of cryptocurrencies out there now, but Bitcoin is most developed, most adopted, most secure and most stable.


Yep, money tends to inspire a conservative* instinct in all that hold it, commensurately more conservative as the value of the money increases.

That's difficult to align with something as inherently progressive as a radical and developing new tech such as cryptocurrency, and so making careful choices about how/where conservatism and progression can be applied to make a given cryptocurrency both as stable and as agile as possible is what cryptocurrency devs are tasked with. Bitcoin continues to lead on that basis.


* note that this does not mean political conservatism as a package, simply the desire to conserve the exchange value of an asset whose only inherent value is that of a medium of exchange, which is a delicate task. "Conserve" is a real word, that means something wider than its political connotations.
2540  Bitcoin / Bitcoin Discussion / Re: China just like banning things, Google, Facebook, Twitter, then Bitcoin. on: September 18, 2017, 10:29:04 AM
Ugh

The main (and enormous) difference is, that social media and search engines are mysterious businesses with no obvious profit motive. All the services being compared in the OP cost the user zero money to use, at any level. Yet they also all have large teams of well-paid software developers constantly improving their software platforms.

It's been said a million times before: when the so-called product is free, the user is the product.


And that's the real reason why the Chinese government prevents Twitter, Facebook, Google et cetera from accessing the Chinese people. The Chinese government knows that the information produced by these services is the real aim of their existence. They are loss-leading profitless corporations, subsidised by interests in the US government to provide other arms of the US government (as well as other private enterprises close to or run by the US or it's client-state governments) with pervasive and diverse information about the users of these services. The Chinese government doesn't want to protect it's subjects from this, it simply wants to do the same and keep the information to itself. "My god is a jealous god" etc.



So Bitcoin is not really in that category, it's a truly revolutionary software concept that liberates people, instead of adding simply another layer of (well-disguised) subjugation. It's so powerful that most government pronouncements vary from very negative, to vaguely well-meaning (which I take to be a euphemism for "when we think of how, we'll be banning it". Good luck with that one, gangsterments).
