When China blocked new ICO's and the sale of Bitcoin, it hurt the price of Bitcoin. Have other prices also fallen?

Were there any which were not affected? Or that went up?

Thanks.

I understand that when the lucky provider is first to have updated the blockchain database, that individual is rewarded with Bitcoin and thousand of dollars in administrative fees. Is this consider "proof of work?"

Is it one system that wins, or is it normally an entire network?

Does anyone have an idea how many systems are competing, in parallel, to be the lucky one that finishes first?

Thanks

I skimmed this article, but do not get a warm fuzzy feeling. Does the suggestion that distributing the vast processing requirements of cryptocurrencies into our daily life just mean that the things we get for free will suddenly be competing against a profit center for computer cycles?

And does this imply that a heavy load on crypto calculations will cause a general slowdown of the web? And if currency computations take precedence, what is the worst case possible scenario?

I am interested to know, in the year the gold standard was finally abandoned, 1971...

How many dollars were in circulation at the point in time?

In our Outllok porate mail, I was asked to help in order to configure a mail that everytime the suer opens the mail, it automatically runs the video file. Is it possible?

I'm working with an ecommerce API. Once the transaction is processed an HTTP post is sent to a URL of your choice with the transaction data (a way to confirm transaction on your site). This is fine, however how can I confirm the HTTP post is from the applicable source for security purposes? I tried $_SERVER['HTTP_REFERER'] but nothing is provided.

Hi,

We have a small SAAS platform which various companies use to sell basic products. Each company get's their own shop profile on our platform, which they can share and advertise via social media and other channels... so that customers can buy their products.

We would like to provide our customers with analytics to show where their hits and sales are coming from most. For example, if they share their profile by:

- Facebook
- Email
- Twitter

A - where do the majority of their views come from

B - where do the majority of sales come from

Is there any 3rd party software that we could integrate to do this OR should we look at building something from scratch?

Thank you in advance for your help.

I have a Magento website which synchronises with a back end POS system (plug-in install guide).

I'm trying to determine why the sync is not working (I cannot get support from the POS provider).

The debug shows

What could be causing this? NO sync is running. How can I determine what the locking process is? etc

When the plug-in is installed on a fresh vanilla  Magento 1.9 install it works and products sync.

Working debug ->

I need to get this resolved.  Happy to employ a consultant if need be.

A relative told me bitcoin mining doesn't require us to pay anything, virtually 0 risk
& we get decent returns from it.  

1. Anyone can point me to articles (for newbie) on how to get started

2. Is it truly low-risk or no-risk?

I see there are massive calculations taking place for the purpose of blocking the same BitCoin from being used twice and also to verify that the user in fact has that amount of BitCoin.

So, on this issue of the BlockCain database being the holder of the sole ledge, verified by numerous bookkeepers...

How long does it take to find out that one user tried to use the same 5 BitCoins, twice?

Is that real time? (under 25 milliseconds)?

Or does that kind of error occur seconds, minutes or hours later?

Thanks

I am not a mathematician, but as an engineer am miffed about the high costs of the whole mining process.  I see the high environmental cost (in electricity used) and the number of PC needed as a barrier to massive penetrations, and I hope to find a "poor man's solution" which would not degrade the privacy protections nor the "trustless" nature of BitCoin transactions.

I read that the code for BitCoin is pubic domain. I also saw there are Bookkeepers watching every transaction.

Is the code these Bookkeepers are running also part of the Open Source paradigm? How about the part which generates algorithms which get distributed to those who've committed their machines for "mining" operations?

Please let me know.

Thanks
