    I am looking for Start-Ups to join the new program by the Chief Scientific Office “מסלול סיוע לקידום חברות מתחילות”. This new program provides funding also to Product Marketing activities. The program will fund 50% of product development cost (including 20% O/H) for 2 years up to 10 Millions IS. It is a one phase application and approval covering the 2 years. After getting approved the entrepreneurs will have 6 months to get the investment for the additional required funds required for the project. The New Program assumes that a positive evaluation and an approval by the CSO will support Start-Ups in getting additional investment. Call me[masked]

      ביום רביעי יש התכנסות לא פורמלית בפאב המיידלרס בחיפה.

      לגבי מפגש יותר מסודר - אנחנו חושבים לארגן מפגש ביוני בחיפה, עדיין אין משהו קונקרטי.

    have a look at: http://bitcoincharts.com/­
    there is a pie chart under the title: "Hashrate Distribution"
    I see that about 51% goes to "unknown", and there are a few other, smaller, "unknowns".
    Is that a specific "unknown", meaning that a certain group/person is producing more than 50% of the bitcoins?

    1 · March 22, 2013

    • Meni R.

      Not sure what you mean. In the chart I see there is about 30% "unknown", plus a small piece of "other known". The latter are sources that are recognized but are too small to deserve their own label in the chart.

      March 23, 2013

    • Ofer R.

      I see about 50% labeled as unknown (on the left), then another ~10% labeled also as unknown (bottom-right), and a third labeled Other Known.
      You can see the image I'm referring to here:

      or here:

      I understand from people's answers (Michael and Ron) that that doesn't mean the there are two "unknown" entities (as in two people or two companies) that have 50% and 10% of the mining, but that there are many unknown _different_ sources.
      If that's the case, then there is no problem.

      March 27, 2013

  • Estrella D.

    I have raised this in the past....this "unknown" origin is bothering me. The market share of the unknowns bitcoin mining pools is huge!

    1 · March 22, 2013

    • Ron G.

      "Unknown" isn't a single entity, it's probably just solo miners.

      1 · March 23, 2013

    • Ofer R.

      I wonder why are there a few parts labeled "unknown" in the pie chart instead of a single one..

      March 23, 2013

  • Ron G.

    Great to see old and new faces, thanks all for attending!

      Thank you for a great meetup and the pizza, as we both know that the cake is a lie.

      March 22, 2013

  • Ofer R.

    The initiative:
    I'm sure everyone that came to this meeting was a "sold audience" in the sense that we believe e-currency should work.
    I'm also pretty sure that people, like myself, have ideas about how to "spread the word" and make a profit on the way (aka "start-up").
    That being said, I think many good connections can spring from these meetings, so if anyone has an idea and/or is looking for a partner, this can be the forum to post on the subject.
    Personally, I have a few ideas but I don't have an intention of leaving my workplace, so time is a constraint for me. Even-so, I'd be glad to hear about ideas, be a part of an initiative and get more involved, so if anybody can offer me that I'll be glad to take it :)

    1 · March 22, 2013

    • Ron G.

      Thanks.

      I believe there will be a business/startup oriented meetup in the near future. We (everyone, not just Meni and me) need to organize it.

    Comments about the meetup:
    My **personal** opinion: I think the Q&A part was the best part, followed, in greatness, by the legal & regulation point of view (after all, our goal is to create a community of law abiding citizens, no?).
    Personally, I'd like to have more time for Q&A 'cause people's questions were very relevant and interesting (even when they hogged the mic ;) ).

    Bitcoin is $3 up since the beginning of this meetup..

    3 · March 21, 2013

    • Tom B.

      5$ already :)

      2 · March 21, 2013

  • Ofer R.

    I am sure these questions were asked before, so if you have a relevant link that'll do:
    1. There will be 21 million coins, will the coin's value be stable enough so it will be possible to set a price to a product without needing to update it every day/week/month, and for the users to grasp the coin's value without the constant need to compare it to other currencies (as we do with the Shekel)? In other words, how will deflation be stopped (or slowed to a reasonable state)?
    2. Is there a good, simple, explanation to what promises the mining to stop at 21 million? And the answer "it's the algorithm" doesn't count ;)
    3. I'm taking the train from Rehevot if someone wants a travel buddy :)

    March 20, 2013

    • Ofer R.

      Let's see if i understood: if I mine a part of a bitcoin every time that bitcoin is used in a transaction I get a fee?
      If not, then when do the miners get the fee,
      if so, who determines the fee?

      March 21, 2013

    • Yuval S.

      Not quite. You get the miner fee whenever you sign a block. This is determined by the block "height" i.e. it's place in the chain and the transaction fees within this block as I explained

  • Maayan K.

    Anychance someone is coming from south TLV and have a place for me and my dog (in training to be a service dog for the blinds)?
    Will pay for gas and promise to not sing along the radio...

    Dear Organizers - will it be in Hebrew or English?

    March 21, 2013

    • Meni R.

      The lectures will be given in Hebrew.

      March 21, 2013

  • Andrew V.

    What is the optimal way to get there... bus number?

    March 21, 2013

  • Meni R.

    There will be a sale of Yubikeys at the event, the price is 100 NIS, payable in cash or BTC.

    March 21, 2013

  • Andrew W.

    Is there anyone coming from Haifa that wants to travel together?

    March 21, 2013

    • Michael F.

      though if some one can give a ride it would be nice.

      March 21, 2013

    • Ilan R.

      I'm coming from Haifa, but I'm without a car as well

    In Response to Cyprus Panic – BITCOIN HITS NEW ALL-TIME HIGH OF $50….er, $52, $54, $55. Bitcoin is both suspect and inspiring. Not a sure thing by any means, but worth the try!!!

    1 · March 21, 2013

  • Revital c.

    If there is lets say "traffic jam" in the information flow and all the System of bitcoin net crush - will there be a restart to it with all the money lost? As its just starting from a new point again? Or is there an automatic way that saves all the memory and calculation that already been made
    An example was the bug few days ago... Did it have major effect or not? On all the users information gathered to that point

    March 20, 2013

    • Meni R.

      The blockchain data is replicated on thousands of computers (in persistent storage), so it's unlikely to be erased.

      The fork caused by the bug didn't have a major effect. For most people it had no effect whatsoever.

    Next time :)

  • Ido G.

    Hey Ron - Thank you for the lecture yesterday at Campus TLV.
    It was very informative...
    Btw, what is a recommended site for Israelis to buy bitcoins?

    3 · March 12, 2013

    • Ido G.

      Thank you sir... I'll check the options you mention.

      March 13, 2013

    • Ron G.

      The site is currently down due to some technical/regulatory issues, but it will hopefully come back online after some technical/regulatory issues are resolved (no specific ETA yet). You can look for other options.

      March 13, 2013

  • Aviel L.

    It would be nice if we get some more technical lectures because most of us already know the basics. Especially if you guys can get into describing the bug that was found few hours ago and its impact. BitCoin like any other currency is all about trust. How can we trust BitCoin when the software that's dealing with it is not bug free!!

    2 · March 12, 2013

    • Meni R.

      Aviel - you know the basics but most people who will come to the meetup don't.

      The technical details of how Bitcoin works is difficult to explain even to technical people, let alone laymen. It's not remotely in the scope of this meetup.

      I might say a few words about the fork bug, but all software has bugs, the question is how severe the impact and how quickly they are fixed. In this case the impact was practically 0 and the root cause will be quickly fixed.


      You should consider arriving later to skip the lectures which aren't relevant to you.

      March 12, 2013

  • Ariel H.

    Anyone coming from Jerusalem?

    March 8, 2013

  • zvika v.

    Is there any chance to hear about bitcoin and taxes in Israel ? I would like to hear some details from an Accountant, if possible.

    March 4, 2013

    • Aviel L.

      That accountant may support the view that Bitcoin is a currency but I doubt the Israeli govt will support that too... What about Gold? Is it money? Used to be money? People all over the world pay taxes for gains in gold!

      March 4, 2013

    • Ron G.

      I suggest we discuss this on the Google Group, it's more suitable for this than meetup.

      March 4, 2013

  • Yesha

    I hope I can make it
