The fork will not happen without miners' explicitly signaling consensus by updating the version number in the blocks they create.

But a miner can rollback to running a node that does not implement the hard-fork in just seconds, should there be any doubt that the hard fork might not succeed.  So just like in March 2013 when v0.8 blocks were ahead by a wide margin that didn't mean that side would ultimately continue as the longest chain.

Firstly it assumes that miners are driven to much by economics and to little by politics than is probably true.  I'm sure that most of the miners who count these days have every likelihoods of looking out days or weeks into the future and taking a monetary hit for a future enduring reward.

If that were true, p2Pool would be among the top 3.
163  Bitcoin / Bitcoin Discussion / Re: Fork off on: January 11, 2015, 11:08:43 PM
I have a few Qs...

1. Even If all miners accept the fork, can it sustain unless majority of nodes do not update themselves ?

On the technical side, you only need enough nodes using the software that implements the hard-fork to ensure that post-fork blocks get propagated.  But even if *nearly* all miners accept the fork, even if you only had something like 10% still hashing without the changes implemented you'ld still get a block every two hours -- frequently enough to include most high-value and high-fee transactions.   [Edit: (i.e., sustainable for anyone using a node without the hard-fork changes).]

2. If all miners do not accept the fork, then there will probably be 2 blockchains for some time. At that period of time, wont all coins be spendable twice on 2 different chain ?

Yes, that's why it will be so dangerous to accept payments from anyone that includes coins tainted with post-fork coinbases.    I personallly will not have a single millibit remaining on any exchange or e-wallet at the time of the fork if there is any hint of dissent like this.  I will only accept payment transactions that confirm on both sides, ... which can only happen if the transaction had no UTXOs tainted with post-fork coinbases.   Maybe after a week or two and there's essentially nobody remaining mining the original side of the fork will I be willing to accept post-fork coins.
164  Bitcoin / Bitcoin Discussion / Re: Fork off on: January 11, 2015, 10:37:09 PM
Control of Bitcoin rests in the hands of miners when you're talking about a chain fork.

And miners are essentially paid employees/contractors.

The Economic Majority is who the miners work for:

Now what isn't being appreciated is exactly how risky it is to miners to adopt changes that have the potential to put them mining on the wrong side of a fork.

Let's say you run an exchange (e.g., BitStamp), hosted (shared) E-Wallet (e.g., Coinapult), or merchant processor (e.g., BitPay).    If you start accepting bitcoins from miners (which become spendable after 100 confirmations) then you are taking on the entire risk of loss if the proposed fork fails to maintain the lead.   So maybe to protect against that risk you reject any deposits or purchases that include coins that are tainted from post-fork coinbases.  That immediately kills fungibility.  The miners won't want to take on the full risk themselves and begin to dump their newly mined post-fork coins at a discount.  Pretty soon the unchanged side of the blockchain fork gains hashing power and begins to snowball.  The writing is then on the wall.  Maybe 24 or 48 hours later, the proposed fork that initially had "wide support" is no longer the longest chain.

Now when that happens you have havoc wreaked because certainly this was an outcome that some fraudsters were hoping for and the two sides look nothing alike -- with many, many coins spent differently between the two sides of the fork.

I'm not saying I wouldn't like to see a bigger blocksize.  I'm just pointing out that a hard fork will require a huge collective leap of faith -- and even this sole promise of dissent might be sufficient to torpedo that forking effort.
165  Bitcoin / Bitcoin Discussion / Re: Bitstamp hack. A real life test of anonymity in Bitcoin on: January 11, 2015, 06:26:41 PM
There isn't even any proof that Bitstamp was ever hacked.

Exactly.  If we were to start treating these coins different from any others (e.g., by blacklisting them) then that provides an opening for all kinds of abuses (by those who might falsely claim "hack!" in an attempt to get the funds back or drive some other outcome.)

Having trouble logging in.   I know I am using the right password because if I try using an invalid password I get a warning.  After entering username and password I am brought to whatever page I was at when I wanted to log in, but the "Log in" link at the top right is still there -- meaning there was no authentication.

169  Bitcoin / Project Development / Re: #BitcoinAfrica -- your help required! on: November 15, 2014, 01:56:06 PM
Maybe, but for Bitcoin to be succesful in many parts of Africa it will have to be able to operate on USSD/sms level mobile phones.  I would imagine this would be centralised wallets operated by a mobile service operator or similar.

Safaricom is partly owned by the government (Kenya).  I would bet hell would freeze over before Safaricom would give  a Bitcoin wallet provider access to their local USSD gateways (which are required for secure communication of mobile-originated requests.)

Right now most new phones sold are smartphones.   This still means only a small segment of the population ... (like less than 20%) has a smartphone today but that's not as huge a hurdle as it may seem.  Families and neighbors are used to sharing resources.  Those that don't have a feature phone even yet today might have their own SIM card though.  With this SIM card one can borrow a phone to use M-Pesa, for example.   With an inexpensive hardware 2FA device a person without a smartphone can safely borrow someone else's smartphone to make a Bitcoin transaction.  Even paper-based wallet using BIP-38 might be useful with a borrowed phone (one that is provided by the merchant even), presuming the password is single-use (i.e., spend all funds in that wallet and the wallet is not re-used).

The amount of spam I'm receiving from this dude's operations is growing steadily ... he's the "meetup organizer" for meetup groups in more than a half dozen cities (including L.A., San Francisco, and .... Vancouver ... that's a red flag), and I see nonstop spam/announcements from his other sites I joined to monitor.   This is getting worrisome ... is he pulling a long con?

177  Bitcoin / Meetups / Re: Bitcoin Kenya Meetup (Nairobi) on: October 16, 2014, 02:03:46 PM
Does the Meet Up venue accept Bitcoin?

Neither Pete's Coffee nor Brew Bistro (the two host locations, to-date, for the monthly meetup) accept Bitcoin yet.  They are both located in office buildings with startup incubators (Pete's Coffee is in the building that hosts iHub as well as USHAIDI, Brck, GSMA, & others, and Brew Bistro is in the building that 88MPH sits) so there are plenty of techies, many of whom would pay with Bitcoin.

Perhaps once BitSoko starts rolling there will be more merchants in Kenya willing to put up the "Bitcoin Accepted here" sign.

Do you know whether it is legal to sell bitcoins in Saudi Arabia?

Saudi Arabia has lots of "informal value transfer" network activity (e.g., Hawala) though I don't know what is considered "legal". 

Perhaps there's more info from these sources:

No fatwa has been issued against the cryptocurrency,

And there was an event earlier this month and several events last month (including a booth a the State Fair !!!):

So join that meetup group if you haven't yet and it'll send you e-mail when any upcoming meetups get scheduled.
180  Other / Beginners & Help / Re: Orphaned blocks and transactions on them on: August 27, 2014, 06:23:05 PM
I don't think transactions can get lost? that would be ridiculous  Huh

Happens all the time.

Transactions that don't confirm (e.g., with six confirmations) eventually get dropped by the miners (due to the limited size of the transaction pool which is in-memory only.)

There is even the possibility for a confirmed transaction to get "lost".  That happened with the March 2013 hard fork where a customer deposit to OKPay had confirmed, but then that customer took advantage of the hard fork situation to create a double spend against OKPay.  Due to the situation, the miner that included the double spend (BTC Guild) had already known of the original transaction on the v0.8 side of the blockchain fork but then included the double spend of that same transaction when they switched to solving blocks on the pre-v0.8 side of the fork.      So BTC Guild "lost" the first spend transaction -- likely due to re-starting the client which, at the time, had no method of pulling the transaction memory pool from a peer or from permanent storage.   

That's a very, very rare situation.  Though it could have been a $10,000 loss to OKPay had the customer not returned the funds that were double-spent.
