1) Due to Google's predatory practices and established connection with scumbag "intelligence" agencies, google has been banned and blocked for over a billion internet residents.  Using google captcha makes this site unusable for a billion people.  Is that your goal? 

2)  Google captcha is the slowest one available.  If your goal is solely to waste the time of those users who can still access the site, use google captcha.  How many thousands of hours have you wasted already with this useless nonsense? 

3)  Google captcha is a good way to say "I hate my users and I'm a moron" 

That'd be all.

To be more specific:  

Soon woodcoin will have a larger block height than bitcoin.  The first astute bitcointalk reader who names the block height at which woodcoin first passes bitcoin, that is the first block height for which woodcoin has a later timestamp than bitcoin's corresponding timestamp of identical height, will receive 50 mBTC from me.  

One guess per person (later guesses will not count).

Good luck!  

7  Bitcoin / Bitcoin Discussion / Strategic tricks played against the bitcoiner on: October 24, 2016, 04:28:51 PM

What could be the two most important political writings of the past decade were both written from prison cells, by political prisoners who spent substantial time in solitary confinement.  One is the "Manifesto for a Democratic Civilization" by Abdullah Öcalan, who had been an important member of the PKK.  The other is "Maroon the Implacable", by Russell Shoatz, who had been an important member of the BPP.

The latter of these describes in one section the problems which plagued a certain liberation movement of people striving for self determination and to escape the existing yoke of an oppressive system.  The American history presented is all too often ignored, and some parts in particular are relevant to the situation which faces current users of public coin systems ((A system where some people work for economic tokens and others simply issue arbitrary quantities in private at no cost is an oppressive system)).  The author outlines how great progress in a first wave of change in such a battle can be lost.  Here's the quote from Russell Shoatz which inspires this post:

Strategic Tricks Used Against the Youth

    Understanding these tricks and their various guises and refinements is the key to everything.  You will never really understand what happened to get us to the present moment or be able to really move forward until you become a master at recognizing them and at devising ways to defeat them.  They remain:

    1. Co-Option;
    2. Glamorization of gangsterism;
    3. Separation from the most advanced elements;
    4. Indoctrination in reliance on passive approaches;
    5. Raw fear;
    6. Drugs

It might be that you don't see eye to eye with me on this analogy of black liberation to bitcoin.  You might consider bitcoin of use as a revolutionary tool, or the opposite: as a counter-revolutionary tool.  You might disagree with my opinion that bitcoin is being adopted by what is effectively a global maroon community, giving individuals and communities democratic leverage against authoritarian systems such as states, republics, corporations, or plantations.  However you probably will not disagree that the use of bitcoin or public coin represents some kind of change to the status quo, compared to the system of the late 20th century.  From here, we must recognize that there are forces, not necessarily consciously due to single or multiple specific actors but forces none the less which collectively work to hold the status quo in place and which use the above techniques to trick "The Youth" (that is, those spear heading the change).  In other words: strategic tricks that work against your vision of success for crypto.  To quote Russel Shoatz again:

  First off, let me make clear that even with all of the glorious strides that youth made within the first wave, they were not the only ones fighting for radical and in many cases revolutionary change.  These young people were usually only the tip of the spear, the shock troops of a global struggle.  They were motivated by youthful energy and impatience, with no time or temperament for elaborate theories. They were rushing forward into the fray, ill prepared for the tricks that would eventually overwhelm them.

    So to understand what happened we must examine some of the main "tricks" used to slow down, misdirect, control, and defeat them.  Without a point, a spear loses all of its usefulness

If we are to learn from this history, and to not make the same mistakes, we must pay close attention to this kind of sage analysis.  So lets consider how the six tricks are used against the youth so that we might escape a lost generation or worse in the struggle to obtain a sane financial system, or at least to give us respite from the debt slavery and rule-by-counterfeit systems as we strive towards more enlightened social systems.



    Co-Option was used extensively to trick just about all of the first wave youth into believing that they had won the war.  Strategically, among every segment of the youth that we can name - university students to lower-class communities - billions of dollars were made available.

Sound familiar?  It should.  Venture capital dollars have "poured into bitcoin" in a process called co-option.  The best and the brightest spearheading the bitcoin revolution (or counter-revoluation if you prefer) were given jobs, titles, and other supposed benefits, provided they play according to certain scripts.

   Supposedly these funds were to enable the youth to determine what should be done to carry out the far-reaching changes they desired.  In reality they were being expertly monitored and subtly coaxed further and further away from their most radical and advanced elements, mainly through control of this funding.  This was part of the strategy adopted by ruling-class foundations, by government, and by corporate Amerika for defeating the youth with sugar coated bullets.

I will avoid mentioning names in this post, because it would be too long.  However mentioning them is important.  Stick to your vision and say no to the sugar coated bullets.  Notice and understand the forces of co-option before you make those important decisions.

Glamorization of Gangsterism

This is perhaps part of the story of the rise of bitcoin as well, in a different way.  Ponzis, exit scammers, web-wallets, premines, wallet thieves, pump-and-dumpers, cloud-miners, ASIC non-deliverables, fake-hacks, real-hacks, and obsolete miners: All have a certain glamor about them if we read the forums and focus only on the fact that they "got the money".  But is this going to help us reach our goals?  Gangsterism ostracizes us from the mainstream and pits us against each other.  You will be happier in the end to call out scammers and to hold the hands of those who might fall prey to gangsters rather than to take advantage of these people for supposed short term gains.  We should at the very least be wary of the pitfalls and the innate push by the status quo to lure us too far down this path.

Separation from the most Advanced Elements

This is really tricky.  It's hard to know who the most advanced elements are or where to find them.  Forums are co-opted, and people claiming to be the most advanced almost never are.  It takes constant vigilance, as there is no authority capable of simply telling you.  We must continuously search ourselves.  We must be willing to consider the opinions of those who might have appeared crackpots, co-opted, or wrong in the past - just in case.  We must be willing to abandon those leaders who might have become co-opted, degenerate, or simply lost their touch and would lead us astray.  We must be wary of forming tight-knit groups that discard potentially vital intelligence as being external.  What makes this task harder still is that we must above all continue to be decentralized.  This is an earlier theme of maroon success, continually mentioned by Shoatz, and fortunately for us one at which bitcoin excels.  However, it makes adherence with the most advanced elements a constant struggle.

Indoctrination and reliance on passive approaches

Because the conflict is an economic one, we might be tempted to say this trick is less applicable.  However the key is education, and in this theater reliance on passive approaches is a major mistake.  Without active education and insistence on the use of public verifiable exchange, when monetary exchange is deemed necessary, there will be no further progress and our remarkable gains will be lost.  Indoctrination in this theater is massive, as every school, movie, TV show, songs, organized religions, nearly every possible facet of media will tell us that privately issued currency is money and that we should just accept that.  On the other side there is almost no regular education of information theory, encodings, public-key encryption, or open-source software management.  To avoid losing ground we need an active approach, simply "Hodling" is not enough.

Raw Fear

From the early days of bitcointalk raw fear was there.  "FUD" of all sorts, yes, and also "bitcoin will be banned".  I'm sure you know the name of at least one coinsman who has been imprisoned or robbed by agents of state or fiat for their noble efforts, as well as various propaganda designed to make their efforts look less noble.  As one early commenter put it:  "Nearly every serious student of the subject seems to believe that Bitcoin will be ruthlessly suppressed in the near future.  The only disputed details appear to be: what form the ban will take, and how it will be enforced."

However in the case of bitcoin, numbers, appearances, and crucially finances are on our side in addition to just common sense, decency, and history.  Educating people in the problems with privately issued currency might seem risky if you just consider the powerful forces in question, but it isn't.  Henry Ford spoke eloquently on the topic, as well as many others over the last century from all positions in the social hierarchy.  If you aren't calling out specific names, then you are not drawing specific ire - and also, you are not alone.

Rest assured - more bank accounts and paypal accounts will be closed, and more arrests will be made.  However if we plan ahead for such contingencies, and recognize the trick that fear can play to make us weak, keeping in mind that this is our chance today to make a difference, we can make decisions which properly weigh all possibilities.


It's tempting to go off on a tangent because drug education and policy is in such a barbaric sorry state, but I'm going to avoid that for now.  We should keep in mind that we will need all our wits about us to navigate this period wisely, and whatever that means in terms of your drug use is for you to determine.  The thing I've personally seen do the most damage to bitcoiners is that king of defocusing agents, the amphetamine, the worst damage of course (as all drug abuse) coming from when it is taken regularly, and with false expectations as to its potential use.

Hopefully I'll get an electronic version of these books up here for you soon.  For now, that's all folks.

8  Alternate cryptocurrencies / Altcoin Discussion / Happy Birthday Woodcoin - Reflections on two years chopping LOG on: October 20, 2016, 03:02:03 PM
Two Years of Chopping LOG

Happy birthday Woodcoin!

I'm going to use this excuse to take a look at the current state of the network and review the motivation behind using woodcoin.

Part 1 PRICE

Fig. 1   Market Capitalization of Woodcoin over first 2 years.

Woodcoin is a small coin listed with a capitalization of ~200BTC.  This puts it at the 109th largest "mineable and non-premined" coin listed on coinmarketcap.  As you probably know by looking at this metric before, it is easily skewed by small distributions of stackers, small volume, and coins burned or lost.  I expect many of the coins in this top 100 list to disappear just like paycoin did.  The half a million LOG sent to the address WeHonorTheForestsAndTheTrees4pPXTQ are not included here so really the spendable coins are at least 6% smaller than reported.

Woodcoin is fully public and decentralized with no ICO, no registered foundation or corporation, nor any solicitation or acceptance of fiat currencies during its creation.  If you squint a bit you can see this in the charts.  One immediately notices in Figure 1 that the usual fractal pattern exhibited in most coins (large fast pumps followed by slow decreases) are not visible here.  Where are the pump and dumps?  Where is the ICO spike?  Woodcoin shows a stable (but slow) growth, which is no surprise to those who understand the supply curve (see details below).  Of course because woodcoin is open to all, this is no guarantee of future behavior.

While woodcoin is currently listed on at least four currently operating exchanges, most all of the volume is on C-CEX.  They have proved to be reliable and trustworthy custodians as of today, and have also shown consistent growth over the last two years.  You know the deal with exchanges by now.

It's also worth pointing out that C-CEX reported LOG trading for as high as 8000 sat (during one emptying of supply about six months ago) and a couple of faucets currently sell them in small quantities for 0 sat.  That should give you an idea of the ranges of prices.

The total supply (including permanently tied LOG) is now just over 8 million LOG.  This is out of a maximum of 27.6 million LOG, which as you probably know, will take a long time to chop Smiley



Fig. 2  Hash rate of LOG choppers over the first two years of woodcoin.

The constant battle which is a proof-of-work network has been very exciting to watch here.  Recently (as in yesterday) the difficulty has touched all time highs.  There are quite a lot of skein hash functions being calculated, to say the least.  The network is currently in the GPU phase of growth, which is to say that the vast majority of the hashpower appears to be in GPU rigs.

There have also been hash withdrawl "attacks" which began almost a year ago, in November of 2015.  Certain GPU farmers dedicated their relatively large rigs to chopping LOG for short time periods, then left the network when the difficulty increased, presumably to mine other coins.  This led to periods of very long block times.  LOG users waited patiently and the network recovered as it should.  While some people reported being annoyed by long confirmation times, all transactions went through.  In addition to complaints there was much discussion on what could be changed (with a fork) to alter these dynamics.  A recent talk by Mark Friedenbach at Scaling Bitcoin in Milan touched on these issues.  Difficulty adjust algorithms such as the one employed by woodcoin look dreadfully simple to a control systems engineer (why is there no PID controller?), but their simplicity and resilience make them work - even if at times their overshoots and undershoots are aggravating.

This summer further hash warfare activity was detected on the network, in the form of block withholding "attacks".  These enabled certain woodcutters to re-chop blocks of LOG (which had been chopped by hash-withrdawl players as discussed above) after the original hashpower was withdrawn.  This caused a certain amount of confusion but good will was displayed by all involved as no transactions were reported double-spent, despite indications that some woodcutters had the power to perform a dreaded 51% attack.  The woodcutters involved even went so far as to generously refund any smaller choppers who had lost their rewards as orphans.  This led one woodcoin user to ask me "Why is it raining LOGs?"  There were even one or two chain reorganizations that numbered as high as thousands of blocks.  While hardly a selling point on the security of woodcoin transactions at that moment, this was very exciting to see that the consensus network can recover from such shenanigans.  Small and decentralized proof of work chain dynamics can be very exciting.

Also related was a brief "Quantitative Easing" period sponsored by the secretive dwarven Kawg trust, in which large transaction fees were paid to woodcutters.  There are rumors that another period of quantitative easing or QE2 will emerge on the network.

Overall the network has behaved well, which even after 8 years of watching bitcoin blocks appear still seems somewhat of a miracle.  Lets not forget this was proven by some of the very best cryptographers to be impossible Smiley


The real motivation is for our betters, the trees, to survive and thrive, and for us to secure our life support and to gain a second spaceship to ensure survival of Gaia.  We fight Sauron's colonial empire within as well as the crawling radiative chaos Nyarlathotep without.  That's a long story we won't get into here.  To get started with that, one thing we need is to remove the gaping wound on humanity and middle earth which reliance on private coin issuance has opened, and to do that we need a strong ecosystem of public coins.  Woodcoin aims to be one of these coins.

When I presented the logarithmic supply curve, and implemented it with the woodcoin genesis block two years ago, I didn't go out of my way to explain it.  Some people figured it out anyway.

The problem we are solving here has been largely overlooked, but it hasn't gone away.  Namely:  What is going to incentivise miners on the bitcoin (or other geometric supply curve coin) network when the block subsidy reward drops to near zero?  Satoshi's answer, and perhaps the only answer that makes any sense, is transaction fees.  However, we have a large segment of bitcoin users who fear that large transaction fees will push users to other coins.  Some even suggest raising the maximum block size to avoid these large fees.  In addition to this big question mark of how the network will work when block subsidies drop to near zero, as they do rapidly in a geometric release curve, this rapid release makes the supply look unattractive to new users for another reason: it appears as a premine and as an unfair distribution.  Currently more than three quarters of all bitcoin to ever be mined are already in the pockets of early adopters.  Many critiques of BTC harp back to this point.  [Half the LOG will be released by 2305.  Three quarters won't be hit for thousands of years after that, I'll let you do the calculation.]

One potential way around these problems which has the advantage of simplicity is to have a constant inflation.  This is the solution of dogecoin and of ethereum: an eventual minimum non-shrinking block subsidy.  This plan has its attraction, but it also might scare new users away because it means that the money supply is not capped.  As time crawls on, value in a single token thus inevitably goes down, and long term store-of-value seekers flee.  Another uncapped strategy is that of many proof-of-stake coins, namely an constant percentage reward, leading to a still faster exponential supply growth.

Fig. 3  Three existing supply curves, taken from Margrit Kennedy "Interest and Inflation Free Money".  Curve A is a geometric release, like bitcoin or litecoin.  Curve B is a constant subsidy, like doge or ethereum.  Curve C is a constant percentage inflated release like most proof of stake coins.

The logarithmic supply takes a middle road between the geometric release curve and the constant release curve (A and B in figure 3). Unlike a constant release curve, the supply is capped - there is a limit which will never be passed (technically due to the discrete nature of the supply, in continuous fields logarithms are unbounded).  However it approaches this limit incredibly slowly which ensures there will be some subsidy to support securing the chain.  Further, there is always an advantage to securing the network today, as compared to securing it tomorrow.  Every block is worth less than its prior.


Once you understand the purpose of the logarithmic release function, the rest of the woodcoin design mostly follows.  The satoshi codebase was the choice of instantiation, due to the relatively well tested nature and the existing tools to work with it.  Several clients have emerged, as well as tools for address manipulation and so forth.  Simplicity is an overall goal here, as we want people to be able to use this just as easily as any other public coin.  Design consideration was conservative, as recommended here.

Once the supply curve was decided, the big question was what to use for a PoW hash.  It's not a good idea to use a hash function that other big coins are already using (for background see why Doge is now mergemined on litecoin or why NMC is now mergemined on Bitcoin).  At the time, Quarkcoin had just come out and people were excited about chaining together hash functions to make it more difficult to do custom hardware.  As I saw it, custom hardware was an eventuality for any coin if it lived long enough to become popular, and chaining hash functions only made the thing more complex and I saw it as reducing the value.  At the time SHA3 was just being chosen, and one of the potential candidates was the Skein function.  Bruce Schneier and three fish told me it worked, the NSA rejected it, some research suggested it was fast and would be relatively easy to optimize in custom hardware, and so I went with that.  I wasn't about to roll my own hash function yet, sorry Smiley  [It's worth pointing out that woodcoin is the current leader in pure Skein hashrate].

The only other major thing different about woodcoin is the elliptic curve.  I've written about this before so I'll spare you the discussion again.  I went with something different than bitcoin because it was easy, well tested, and recommended by many of the experts.  Conservatism again, boring but that's the way it is.

The rest, as they say, is history.


Many thanks to all the great folks I have met through this project!  Keep up the good work in all endeavors, public coin and otherwise.
9  Alternate cryptocurrencies / Altcoin Discussion / Addressing the premine - how to compare coins on: August 18, 2016, 06:26:34 AM

Addressing the premine

If you've been following the rise of public coins, you have probably heard the term "premine".  In a public coin, the money supply is public - thus anyone can see when and how all the money was created.  Traditionally, if monetary tokens were distributed before the transactions began on the network, before the transaction validation known as mining began, this was referred to as a premine. for example allows you to filter out premined coins from their list.  But what is their criteria for a premine?

Well it's easy to look at the code some nodes are running and see a hardcoded distribution before mining began.  Coins like ethereum, nxt, and plenty of others obviously have a premine in the code, while BTC, LTC, DOGE, plenty more, and yes even BCN do not.  However, this is not the whole story.

As more and more public coins were released, their creators used different methods to keep certain portions of the currency for themselves.  Some of these were referred to as a "ninja mine".  In this case rather than code a premine into the blockchain definition, they would simply mine the first blocks themselves before publicizing the existence of the coin.

And why not play these games?  There's no reason a priori why a premine or a ninja mine is fraudulent.  After all, the money supply is public.  If people still want to use the coin, then they are at least doing so with the knowledge available to them (unlike e.g. a fiat currency in which there is no way to verify anything about how many tokens have been issued on a given day).  There are many reasons given by various coin proponents that a premine is a positive thing, such as to fund development related to the coin, or to fund an ICO for an initial distribution.  However, an individual wishing to decide which coin to use might be interested in just how premined a coin is.  Well, how premined is your money?

There are two areas of potential interest here addressing the premine, one is how much money was premined, that is how much existed prior to a given moment in time - and the other is who got it.  For the purposes of this post, I will ignore the latter.  In other words, we will assume that if somebody who isn't you got the money, than it's part of the premine.  Sure, you'd rather Alice (and her friends) had it rather than Bob, but lets assume for now that this is a separate issue.

Quantifying premine via a scalar quantity is in fact not necessarily the right thing to do.  The proper way to look at a coin's distribution is to look at the entire money supply curve vs. time.  Some distribution curves seem fair early on and become more front-heavy later.  Others might start out ninja-mined but look more fair later.  But hey, we want numbers, and now!  So lets pick some parameters.

The simplest way to do it is to pick a time interval, and look at the endpoints.  In other words, we are going to compare two points on the money supply curve: one at some time, such as the present, and another in the future.  The method is very simple:


where P is our scalar index of premine, S0 is the money supply at some time T_0, and S1 is the money supply at some future time T_1.

Okay!  So, now for some numbers.

COIN      P0_1      P0_10      P0_30      P10_30      P30_100
BTC              0.96      0.79      0.76      0.96      0.995
LTC              0.90      0.61      0.65      0.92      0.994
LOG              0.93      0.78      0.71      0.906      0.902
ETH/ETC      0.89      0.44      0.21      0.47      0.35
DOGE      0.95      0.47      0.40      0.60      0.42
NXT/RIPPLE      1.0      1.0              1.0              1.0              1.0

Here we have calculated a premine factor for five different choices of the time interval. The first three begin with the present time and extend to one, ten, and thirty years in the future.  The next is the premine factor which one would find ten years from now, comparing to thirty years from now. The final factor is what one would find in thirty years, comparing to a hundred years from now.

The first thing we notice is that premine factors for coins like NXT and RIPPLE don't change regardless of the interval in consideration.  They remain fully premined.  One advantage of such a monetary supply curve is that there is never any supply inflation.  However, there is also no incentive for new miners to come in and secure the network.  This means there is also a disadvantage due to resulting centralization.

Another thing to note is that even though ETH/ETC has a hardcoded premine, it doesn't look so bad with our premine metric.  Why is that?  The reason is the infinite inflation schedule, with a fixed reward per block, just like DOGE.  In fact our shortest interval premine factor shows ETH/ETC as the least premined coin.  This looks good according to our metric, as we see that the premine factor for these coins is quite low, even in the longer time intervals.  However, the disadvantage is that there is no cap on the supply and a continual supply inflation.  This makes an effective demmurage and so long-term investors will be unlikely to hold these coins.

The difference seen between BTC and LTC is solely due to the delayed launch of LTC, as these coins share the same supply curve characteristics apart from a factor of four in absolute size.  As we consider later time periods, this phase shift makes less and less of a difference.

The first three coins in the table have a capped supply, and so the premine factor must always increase.  Other coins like DASH and XMR also share this basic pattern, and show a similar P_30_100.  However, the logarithmic supply curve shows its advantage quite nicely in this metric.  Even though the supply is capped and the inflation remains limited, there remains a far greater amount of coinbase to give out to future miners.

Coins like BTC, LTC, XMR and DASH will in another decade or three remain secure and decentralized only if transaction fees are large enough to incentivize miners, due to their coinbase reward dropping exponentially with time.  However coins with a logarithmic supply curve do not have an exponential reward drop but an inverse function.  This allows them to maintain long-term inflation free behavior without hitting an asymptotic wall of TX fee dependence.

10  Alternate cryptocurrencies / Altcoin Discussion / [SCAM ALERT] Mutiple Currencies, warning! on: May 10, 2016, 12:35:03 PM
It has come to my attention that a number of circulated currencies are in fact privately issued dimensionless tokens, that is, scams of the most blatant nature.  

Some affected currencies:  USD, CNY, EUR, JPY, GBP, ...

NOT ONLY are these coins significantly premined, but developers and hackers CONTINUE TO ISSUE THESE TOKENS IN PRIVATE.  

I repeat, there is nothing at all to stop developers and hackers from issuing these tokens to themselves IN ANY QUANTITY AT ANY TIME.

And further, there is no way for us to know how many are thusly issued!!

Wow.  Talk about scammy, eh?   No other coin in this forum is such a blatant scam as that.  But wait, it gets worse:

1) No transactions are ever publicly confirmed!  That's right, there is no public transaction record.  Block time is effectively infinity.  

2) Significant association of these currencies exists with criminality of all the worst types from pedophilia to terrorism

3) Completely unregulated money supply, no public oversight is possible.

4) Proceeds from the private issuance of these tokens and selling them to unsuspecting public has been used in the most
atrocious and wasteful activities in history from massive environmental destruction to warfare.

Be advised: participation in such a scam as this is unlikely to be forgiven.  Spread the word and be vigilant to avoid any contact with these tokens.  

11  Economy / Gambling / Block-Roulette - Bet on the next bitcoin block on: March 16, 2016, 01:15:54 AM

比特币 区块 轮盘赌


This thing is basically self explanatory.  Your bet, sent to a static address, is on the table when it is confirmed in a block.  The ball rolls around on the table - where the ball lies is determined by the last 5 digits of the next block hash.  We pay you accordingly (minus .0003 miners fee).

Please do check "table status" to see how much cash is on the table to ensure you don't bet too much, and whether the croupier is up to date on the current block height.

There are three croupiers manning the table to ensure you can play 24 hours a day.


This thing exists mostly due to problems with the first generation of provably fair games:

1) It's not easy to verify the declared fairness.

Checking usually requires downloading a hash of a server seed before playing, downloading the seed itself after playing, checking the hash, checking a whole series of bets, and possibly other steps.  How many players really do this?

2) It's sometimes still vulnerable

There have been strategies the site operator could use to cheat you. One thing they could do is search through still-possibly-verifiable seeds (seeds which would have generated existing previous history) and find one which will make your bet still lose.  Another is to use house bets to move your bet into a different position in the bet order -  if the bet order matters, you can be cheated. 

As you can tell, we got rid of these problems here with block-roulette.  All entropy comes from an ideal stochastic source: the hash of the next bitcoin block.  Betting order doesn't matter.  The down side of this is waiting for the block.  This isn't instant payout anymore.


In fact, even though block-roulette is a big improvement, we still aren't provably fair (it's unclear such a thing really exists).  There is a strategy we could use to cheat you.  Namely, after you place a bet - we see the bet and somehow (possibly through miner collusion) put a bunch of other bets in front of yours in the block.  Then when it comes time to pay out your bet, the table will be empty of cash.

If we ever did this, it would have a very distinct signature.  It wouldn't be worth our while as the game would die.  You can further avoid this by keeping bets relatively small (in potential payout) compared to the available cash on the table.

15  Local / Altcoins (Deutsch) / Woodcoin: Eine Elektronische Peer-to-Peer-Währung, Erschaffen Für Stabilität Und on: February 15, 2016, 04:35:22 PM
 Wir beschreiben hier die Überlegungen zum Design von Woodcoin, sowie dessen Implementierung, mit Fokus auf den Eigenschaften, welche Woodcoin von anderen Kryptowährungen abgrenzen. Ähnlich wie Bitcoin ist Woodcoin eine Kryptowährung. Jedoch ist Bitcoin so entworfen, dass es einer nicht erneuerbaren Ressource gleicht: Gold. Woodcoin hingegen gleicht eher einer nachhaltigen Ressource. Insbesondere verhindert Woodcoin zeitliche Asymmetrien welche bei Bitcoin durch seinen Schöpfungsmechanismus auftreten. Dadurch wird ein Anreiz zur Partizipation, geschaffen, sowie die Langlebigkeit von Woodcoin gewährleistet. Unsere Lösung basiert auf einem logarithmischen Wachstum der Geldmenge. Zusätzlich skizzieren wir die Gestaltungsüberlegungen hinter den beiden anderen Änderungen des Kernprotokolls: Mining mit der Skein-Hash-Funktion, sowie die Absicherung von digitalem Besitz mithilfe der X9_prime256v1 Kurve durch ECDSA.
16  Bitcoin / Bitcoin Discussion / Vote on whether you want bigger blocks - by signing with your coin on: August 20, 2015, 06:57:07 AM
A lot of folks have used the word "vote" in regards to the discussion about whether or not we should treat a block with size > 1MB as valid.  

I'm not saying a vote is the solution, but I am saying this: We built a platform for you to place and count verifiable votes.  

Maybe, just maybe, the people who hold the coin might have some say in the matter?   I'm mostly curious what people who actually - have bitcoin - think, rather than some anonodweebs or pseudodevs.

Go, place your vote.  It's free, safe, and publicly verifiable, and if you don't like the wording - make another.    

For more information on the voting system:

17  Bitcoin / Bitcoin Discussion / Thank you bitcoin educators! on: August 18, 2015, 01:34:31 PM

There seems to be a lot of talk lately with "developers" comparing the sizes of their bitcoin cocks.

How many pull requests did you have accepted in this or that software repository?  Were you the first to implement this or that protocol in this or that broken product? 

You know what?  I don't gaff. 

Are you a "core developer" ?  Do you have keys to a centralized source repository or perhaps the ability to censor this or that centralized schoolroom bulletin board? 

I still don't care. 

Some of you are in the above mentioned schoolrooms and repositories, day in and day out, telling pseudonymous noobs (like yours truly) how ECDSA, bitcoin, computers,  and the world works.  And this is what you are: bitcoin educators.   

And for this I love you.  This is the real work that is needed, and you are doing it. 

Perhaps your version of multisig or mining or z-client or whatever - is commonly used / totally broken / fantastic / abandoned.  These details are certainly interesting, from a technical and historical perspective.  However the real impact is pedagogic. 

I hope you see that. 

Yes, we need good software, and this is also a hugely important task which I am not discounting here.  But what good is a decent stack if nobody has a clue what it is or how to use it? 

We need educators of all levels.  This is what holds us back: we are not primarily in need of protocol improvements or better GUIs or whatever, but of people that have a clue.     

I'm trying my damndest not to mention names here, because you know who you are. 

It's been called God's work.  It is largely thankless and without compensation, and I for one say:  Fucking Thank You!!

Bitcoin is intelligent.  No, I don't mean that it is a good idea, or clever people use it.  I mean that the network itself is conscious.  Sound crazy?  Yeah probably it is.  Anyway here's my blog post about it:

Let me know what you think.
