1  Alternate cryptocurrencies / Announcements (Altcoins) / [ANN] NexusCoin - Local Coin for the Israeli Crypto Community on: January 03, 2014, 07:53:33 PM

We decided to get a coin rolling and it got a lot of enthusiasm in the Israeli Bitcoin community. As you must know, the Israeli Bitcoin community is one of the largest and most active communities in the world. After announcing in advance, the genesis block was mined on the 3rd of January 2014, 5 years after Bitcoin's genesis block.

Activity is happening in the official Facebook group (mostly in Hebrew, English is more than welcome!).

Jon Matonis, executive director of the Bitcoin Foundation, is also a member of the board of editors in the Bitcoin Magazine and now also a contributing editor of CoinDesk. All that's left is for them to put an agent in The Genesis Block and they're your classical american corporation.
4  Bitcoin / Bitcoin Discussion / Why I donated bitcoins to Wikipedia via the community pledge on: August 11, 2013, 10:57:05 AM
Wikimedia, as is well known, does not accept bitcoin donations. The reasons vary, but lately some informal discussions with Wikimedia fundraisers have raised some pragmatic issues, being unsure how much it is practically worth to start accepting bitcoins (A/B testing, payment processing, choice paralysis, etc.).

So Meni Rosenfeld had a great idea. Let's start pledging money in a community effort, until Wikimedia sees how much money is waiting for them and decides it is worth it. And if they won't take it now, the pledged funds will continue sitting there until they do accept bitcoin donations. I donated to the pledge because I want to prove to Wikimedia that the bitcoin community loves their work - because bitcoin is in line with their ideals of a free and open internet. This is most important because Wikimedia accepting bitcoin donations will give bitcoin some very serious legitimacy. I need not remind everyone that Wikipedia is site #6 in the whole internetz. People take Wikipedia seriously, people trust Wikipedia. This is important.

How does the pledge work?

The point of the pledge is that trusted and reputable treasurers (call them "escrows" if you wish) are collecting funds which are solely for Wikimedia to accept once they officially announce accepting bitcoins as donations. These trusted treasurers promise they hold onto the funds and won't use/send them until the goal is reached. If not because of this pledge, then in the next, or whenever Wikimedia accepts bitcoin donations (even if it's in 5 years). Each and every donator can pick a treasurer they trust the most. If you are a trusted and reputable member of the community, please offer yourself as a treasurer!

I donated bitcoins to the community pledge because I'm confident my bitcoins will not move until the goal is reached. If the pledge works, I successfully donated bitcoins to Wikimedia. If the pledge doesn't work I will eventually successfully donate bitcoins to Wikimedia - even if it's five years down the road (unless you don't believe bitcoin will be as successful as I do).

Please join us! Let's get Wikimedia to shut up and take our bitcoins!!!
5  Bitcoin / Bitcoin Discussion / Where do I find quotes from the media on bitcoin? on: August 04, 2013, 06:29:10 PM
I'm writing a guide to bitcoin, and I'd like to be able to have a few positive quotes from some major recognizable publications, stuff like "Bitcoin is the future of money", etc.

Anyone know if there is a list or collection somewhere?
6  Bitcoin / Press / 2013-07-30 Ha'aretz; Israeli lawyers may be paid bitcoin, says Ethics Committee on: July 30, 2013, 12:20:55 PM
Lawyers may be paid in bitcoin, says Ethics Committee of the Bar Association

Ha'aretz is one of the leading newspapers in Israel (biggest "left-wing" newspaper).

Google Translated:
Bitcoin could pay attorney says the Ethics Committee of the Israeli Bar
Israeli banks Bitcoin trading limit, but the Ethics Committee of the Tel Aviv District - Center of Bar Association certifies its members get paid Distributed Virtual currency

Israeli lawyers may get paid Bitcoin, so set this month Ethics Committee of Tel Aviv and the Center of Bar Association, despite regulatory issues surrounding the standalone virtual currency. Israeli banks restrict non-status currency trading - is clear, and the Bank of Israel has not yet decided whether to charge them to allow trade it or forbid.

Bitcoin is a decentralized virtual currency without a central control system based on encryption and mining which was presented in an article published Satoshi Nkmoto (probably a pseudonym). Anyone with an Internet connection can possess, use and trade Bitcoin, even under a false identity. Secret character allows to use it under the radar of the authorities of the economy, tax and enforcement, with his hair in front of traditional currency exchanges dealers set it. However, buying Bitcoins using traditional currencies may expose buyers to the authorities. In 2012 the European authorities have granted official status of Bitcoin payment method provider has an international bank code, and recently the Bank of Thailand imposed a ban on all use of currency, subject to further testing.

Ethics Committee's decision was made in response to a lawyer's gift of giving market market a law firm. "Bitcoin community Israeli officials asked attorney Market, himself holding Bitcoin, publish situ it is ready to provide legal services for Bitcoin. According to the rules of ethics of the Bar Association, "a lawyer shall not receive a fee for his professional work, but money." Since this is a precedent regarding market turned the Ethics Committee of the Tel Aviv District to get reviews, and after two weeks received approval. "There is no reason to provide legal services in exchange for Bitcoin as payment," he wrote Ethics Committee Coordinator, Michal Krasucky - Ezekiel.

Approval of the Ethics Committee of the Bar Association to Bitcoin fees
Bureau approval stage is one of two that will enable the market for Bitcoin payment, when the second is the regulation of matters of taxation. For example, since you can not invoice Bitcoin, and since there is no "official rate" Bitcoin with traditional currencies, it is not clear by what Bitcoin exchange - easy to invoice.

"The issue of Bitcoin itself raises complex legal questions and complicated," says attorney Haaretz market. "" Difficult to track down those who pay can trigger difficult problems in whole - gambling, drugs, paid for acts that are improper. But now a lawyer may accept fees in cash, and when getting cash is not possible to track the source of the money. Could happen in case you get money from X to represent a person Y. I personally think the ethics committee should not decide moral questions, unless them Bitcoin is a legitimate currency. According to their decision, the answer is positive. "

Attorney providing market received permission to charge fees Bitcoin
In April, Army Radio reported that Israeli banks make it difficult to purchase Bitcoins. A month later, a customer complained International Bank, collected baht, that the bank forbids him to trade in currency. "Virtual coins are anonymous and are not supervised. Activity which is not regulated and therefore has a high risk to the bank, "said his bank. Response to the gaps in the bank added that" the activities currencies and virtual is not regulated and / or supervised and has a high risk of money laundering and terrorism financing. "Bank of Israel said at the time that" supervision the banks have not found it necessary at this time to ban or require banks continued operations with customers engaged in virtual currency (including Bitcoin). Conventionally, required banks to examine the various aspects and risks of each task with unique characteristics, setting limits and controls, and the very existence ".

You look strange decision, given the ambiguous status of Bitcoin?
Market: "Definitely a complex issue. Different entities here have seen the Bitcoin shapes. Publications I know Bank of Israel says Bitcoin exchange is legit. Ethics Committee had to decide only if it receives proper compensation for the services attorney. There are other questions, but they are not its authority and responsibility. "

EDIT: changed title to include "Israeli"
7  Bitcoin / Press / 2013-07-24; Coindesk; Israelis can buy bitcoin in person with local exchange on: July 24, 2013, 05:07:40 PM

Israelis can now purchase bitcoins at their local exchange bureau thanks to a new collaboration between bitcoin exchange Bits of Gold and Global Money Transfer (GMT).

The partnership with GMT means Bits of Gold can ensure it complies with current and future anti-money-laundering and know-your-customer regulations in Israel. At the moment, the maximum amount of cash people can change into bitcoins via Bits of Gold is 10,000 Israeli new shekel (around $2,800).

Get 51% of the hashing power, and don't include any txns that you call "spam".

Or, just change the code of your bitcoin software to ignore blocks with "spam" in them.

Or, just stop complaining that people are using bitcoin. Don't like the largest blockchain? You know, the one that the most hashing power agreed on? Don't use that blockchain! Go find a blockchain that you believe in and call it "the real bitcoin".

11  Bitcoin / Press / 2013-06-04; I Just Used Cash -- Boy, What A Horrible Way To Pay For Things! on: June 05, 2013, 02:15:10 PM

I made the mistake of using cash to pay for my lunch yesterday, and I immediately regretted it.
Because after taking one dirty piece of green paper out of my wallet and handing it to the cashier, I got several dirty pieces of green paper back--along with a fistful of heavy metal disks:

I had to stuff the many pieces of dirty green paper into my wallet, which made it even fatter, and and I had to dump the heavy metal disks in my shoulder bag, which made it even heavier.
And that exchange reminded me why cash is a horrible payment mechanism and why the complete transition to digital payments just can't come soon enough.
12  Bitcoin / Development & Technical Discussion / Quick and safe confirmation for merchants and in client-side code on: May 28, 2013, 03:45:38 PM
I've seen too many software (and merchants using such software) waiting way too long for too many confirmations. Even 1 confirmation is too much for most transactions.

End users hate waiting for confirmations, especially if it's on their phones. As a user, why do I need to wait 3 confirmations when buying something for $10??
Programmers want to cover their asses when transactions need to be confirmed. What if the merchant thought he was paid $5000 but was double spended?

Network propagation

My understanding is that miners take the first transaction they receive, and henceforth throw out any conflicting transaction received after that one. What does this mean? If my transaction propagated throughout 90% of the network, a fraudster would need to either convince the miners to dump that transaction and take a new one (the double spend) or to transmit the new double spend transaction to the remaining 10% and hope they will find the next block.

In other words, the confirmation process is as follows:
- the buyer transmits the signed transaction (good for the smallest transactions)
- this transaction reaches most miners before any other conflicting transaction (good for most transactions)
- it enters a block (good for large transactions)
- buried deeper under more blocks (good for the most high-value transactions)

14  Bitcoin / Bitcoin Discussion / Your bitcoins if you die: time locked transactions? on: May 14, 2013, 12:28:39 AM
tl;dr below

I'm young but the world is full of surprises, for better and for worse. So I've been thinking, in the unpredictable yet inevitable event of my death, how would I make sure that my bitcoins were left behind for those I care for.

I figured the best way for me would be to sign and print a time locked transaction one year in advance, along with the private key to the receiving address. This can be placed anywhere I expect my family/friends to find. The idea being that if something unexpected happens, my loved ones would have to wait no longer than a year to broadcast the transaction and receive my bitcoins. I, of course, would update this transaction once a year (destroy the old, make a new) or move the coins to a new address and sign a new time locked transaction.

I understand this is technically possible. If I were to use, the lock_time is simply the absolute block height from which I would like the transaction to be valid?
15  Bitcoin / Press / 2013-05-07; Police arrest 30 in raid on online drug network on: May 08, 2013, 12:52:41 AM
Police arrest 30 in raid on online drug network

Police from the national economic crimes unit on Tuesday arrested 30 suspects they say ran an online drug distribution network, cooking and selling drugs through using the “Darknet”, according to police.
Police said that they believe the system may have been using "bitcoins", the peer-to-peer digital currency.

Sounds similar to the Silk Road.
16  Economy / Economics / On "intrinsic value" and why it actually means "subjective value" on: April 20, 2013, 02:16:49 PM
What is "intrinsic"?
According to Mirriam Webster: "belonging to the essential nature or constitution of a thing". We are talking about something absolute. The absolute property of a thing.

And what is "value"?
Here it is said to be "relative worth, utility, or importance". This is relative. The relative relation someone has with a thing.

So when someone says "intrinsic value", do they mean that something relative (value) can be absolute (intrinsic)?

Well, you see, "intrinsic value" is simply what a gold lover would call "intrinsic property that I value". Gold has intrinsic properties that are worth some people's time and effort. But if this gold lover would be stuck on a desert island thristy and hungry with nobody to help him or trade with, he would probably have no interest whatsoever in gold. Even though it is a powerful metal and conducts electricity.

So when people say "instrinsic value" what they mean is "intrsinsic property for which people usually assign value, but not everyone and not always". I call that subjective value.

See, if you gave me a piece of gold, I'd hold on to it. Not because I need it. I'd hold on to it because I know someone else will want it. Maybe that someone else wants it because they want to make a piece of jewlery. But even though I don't make jewlery, I still understand that this piece of gold has something intrinsic about it that makes it valuable to someone else.

The same can be said about sheep (for shepards), peanuts (for elephants), dollars (for coke sniffers), and bitcoins (for anyone with a computer or smartphone).

If you ever want to say "intrinsic value" ever again, please instead say "subjective value". And from now on you can say that bitcoins have "subjective value", because I personally am willing to give you work or money for them.

I'm dying to make it first to these articles just to make the first comment something like,
"New rule: if you didn't read the white paper, understand the basic concepts including but not limited to the POW system, the blockchain, p2p technology, open source communication protocols, hashing algorithms, public key private key cryptography, etc., you are NOT allowed to comment. Thank you!"

What can you expect...
20  Bitcoin / Bitcoin Discussion / What to say against the claim "backed by the state/bank" on: March 30, 2013, 02:01:44 PM
When people say that Bitcoin is not backed by any government or central bank, you can now officially tell them that the Dollar and the Euro aren't either.

I've opened the wikipedia article on the Euro, and it doesn't mention the word "backing" not once.

If anyone ever tells you that the Euro and Dollar are more guaranteed than bitcoin, yell at the top of your lungs "LIAR! THIS PERSON IS A LIAR!"
