Are you saying there's a chance that you every user of your pool's funds!?
Or did I misread that?
I write about corrupted wallet that needed a recovering, but standard tools (-salvagewallet) don't working.
Do you have ANY other copies of the wallet (or the keys) that we all have been mining to?

Do you have our zcash?

I had that problem on TestNet, you have to delete the chain in the .zcash folder then re-index
Reindex not working on RC4 and mainnet! (stuck on 145 block) On start I tried launch zcashd 20+ times before get success. Now I hold two separate instances of zcash blockchain for "hotplugging" on zcashd crash, but it can't save from wallet corrupting. I already have one 4Mb corrupted wallet.dat... -salvagewallet don't work, I emailed zcash dev team, may be they can help me repair this wallet.dat, but don't receive answer until this moment.

I'd like to request adding an exchange to BitcoinWisdom.

QuadrigaCX is now the biggest exchange in Canada and has overtaken CAVirtex. BitcoinWisdom shows CAVirtex's feed but not QuadrigaCX's.

QuadrigaCX's API is public and its information is available here: https://www.quadrigacx.com/api_info
I'd imagine it'd be a fairly quick addition since the API conforms to other APIs offered by other exchanges; it should just be a copy/paste/edit job.

Thanks for considering,

They should release it as a torrent with a QRcode at the end of the film for donations. They'd probably get a lot more in the long run

How does the 25% discount work? I just submitted payment, and it didn't seem to have any discount
The discount was already applied.

On October 1st the rate will go up.

Can I pay the fees with Bitcoin? Why only a two year certificate? Most run for 3 years on average.

The fees are only payable with Bitcoin.
The CBP is a 2-year certificate as a result of careful discussion with our advisors. Bitcoin is still evolving very quickly during its formative years and we felt that there would be new topics which will be released and/or invented in the next 3 years that professionals would need to know. That said, 1 year seemed too short, so a compromise was made with 2 years.

A Certified Bitcoin Professional (CBP) is someone who is able to use Bitcoin properly.

Wait, do you think its a good idea to send the message that in order to use Bitcoin properly you have to be a certified professional?
If this is the case, Bitcoin is doomed to never get widely adopted.
No I don't, and that's not how certifications work.

The message we're sending is that people who are able to answer these questions in a restricted time-frame DO have the minimum knowledge required to use Bitcoin properly.

Like with any industry, certifications are not black/white between people who know/don't know about a subject. I come from the information security industry and I know many uncertified professionals who can run circles around certified professionals with their knowledge and experience. You don't need to have a certification to be a good security professional, and you don't need to have a CBP to be able to use Bitcoin.

That said, certificates do prove that you have a minimum level of knowledge. In the security industry, there are many jobs which require at least a CISA, CISM, or CISSP certification before even being considered for the position. Speaking with these HR personnel, they understood fully that there are many candidates out there who would fit the role perfectly despite not having one of these prerequisite certs, however it takes too many resources to risk that role on someone who wasn't certified. What if they seemed good in the interview but didn't actually know what was necessary? The HR paperwork, the month of pay, and the on-site training in the company's procedures would all go to waste while they resubmitted the job description and resumed the hunt for another candidate. By requiring the certificate they knew in advance that the candidates had the knowledge without spending a month to figure that out.

Finally, like with all certifications, they're not for everyone. Many people believe in certs, and many people think they're a waste of money and time.
C4 was built to establish these minimums in our industry in a not-for-profit way. If someone or their business doesn't have a need for measuring knowledge against these minimums, then they don't have to use it; C4 is here for those that do.

The skills that would actually make someone an employable "Bitcoin Professional" would take more that a few questions. I'd want an answer of how you would make web sites and their wallets steal-proof. I'd need to see you code a web interface and a database along with the code to talk to Bitcoin showing you have the skills required to run your own exchange or ecommerce site. A list of commits you've made to Bitcoin itself, or the wallet software you wrote. Being able to "use" Bitcoin doesn't make one a professional any more than your 5000 followers is going to get you a job at Twitter.

See my new signature; also applies to Microsoft, Cisco, and Redhat.
Great points, deepceleron, and we agree with everything except for the name.
A Certified Bitcoin Professional (CBP) is someone who is able to use Bitcoin properly.
A Certified Bitcoin Expert (CBX) is someone who understands the Bitcoin protocol, block format, transaction format, and related technical details. C4 will definitely be testing this knowledge in its CBX exam which is slated to be released this winter. As with the CBP exam, we will make sure the question database has been adequately peer-reviewed by as many knowledgeable experts as possible to ensure they measure competency in each of the topics a Certified Bitcoin Expert should know.

If you feel you are able to assist with this process I'm happy to have you work with our other advisors as appropriate.

Rassah, I see you're "wondering about this."
C4 is a "free-market solution" to a human resource problem. We're not trying to be any more than that. We've built what we feel is an accurate measuring stick because of its peer review and are making it available for anyone to use for comparison. We're purposely doing this as a non-profit to emphasize our mission and not the money needed to accomplish it.

Thanks for your interest, all, and don't hesitate if you have any questions.

Hi guys,

Michael Perklin here from C4.

franky1 is absolutely correct: the CBP exam does not mean you are an expert in Bitcoin. A CBP is someone who understands enough about the blockchain, addresses, keys and wallets to use Bitcoin successfully. They understand what a confirmation is, why they should wait a few for high-value transactions, and backing up/restoring keys to protect their funds. The CBP exam covers 32 separate topics arranged in 6 domains of knowledge.

It's intended to assert that someone meets the minimum requirements to be working with Bitcoin. For example, if you need to task one of your employees to create and manage your company's wallet, you'd want them to understand Bitcoin well enough to keep your coins safe.

9kv, you're incorrect regarding it being an "Internet Certificate."
We mail out a physical certificate to those who earn certification. You can see an example of them on our twitter feed here: https://twitter.com/_CFour_/status/507592388424921090

When it comes to being an expert in Bitcoin, that will be measured with the CBX exam which is due out this winter. That will be targeted at developers, security auditors, and anyone who needs to understand all of the advanced aspects of Bitcoin, such as building a transaction manually or working with the protocol at the byte level. That exam will be much more intensive (250 questions instead of 75) and be administered in a proctored (in-person) format.

There's more information available on the website, or you can ask questions here if you'd like.

I have also received this and am not sure how to proceed.

If we don't participate in the buyback, what happens?
16  Bitcoin / Bitcoin Discussion / Re: Can anyone post an exhaustive list of bad things Bitcoin is doing to this world? on: November 08, 2013, 04:29:25 PM
Financial privacy is compromised due to the traceability of the blockchain.

While you can't immediately tell which address belongs to which person/entity, transactions that you participate in allow you to review details of someone else's financial history.

For example, if you receive your salary in Bitcoin then send me that $20 you owe me, I can follow the funds used in that transaction to find your salary.

Another example, if I give you $50 for something, I can then see where you send that coin. If I recognize the addresses (or can look them up elsewhere) I know exactly what you're buying.

So… Bitcoin is hurting our financial privacy.

There are methods to mitigate this somewhat (use more addresses, split up large transactions into multiple smaller ones) but they require special effort. Most people just send/receive.

AM hash rate is either very very low or completely null at the moment. What the heeeeeell is going on?

FC is selling hardware.  More profit on Gen1 can be made by selling it rather than mining.

Afaik FC is not selling the first model of blades, he was never selling used equipement right? So where are they right now instead of mining?
 
The network is running at about 940 TH/s right now, ASICMiner is probably at 40-ish. That's only 4% of the network. Variance will be quite large at this level. There's an 8% chance that no blocks will be found in 16 hours if you have 4% of the network. So this will happen about once every week.
40TH?

You mean 13TH, right?
http://www.asicminercharts.com/live/

or 1.6% of the whole network...

why do people put "begging bowl" links in signatures. You've got a much higher chance of winning a lottery than anyone ever giving you something. If you turned up at my door saying "donate cash to me" what response do you think you'd get?  Huh
This is off topic, but I'll address it.

In the early days of Bitcoin, it was common for people with multiple thousands of BTC to flip through forum threads and give 100BTC each to random people thanks to their addresses in their signatures.

Yes, things have changed a lot since then.
