341  Bitcoin / Bitcoin Discussion / Re: How many developers are working on bitcoin vs alt coins? on: December 25, 2015, 04:25:17 PM
Bitcoin probably has more developers than any one altcoin. However, there are probably more altcoin developers than there are Bitcoin developers. There are literally thousands of altcoins, and each one needs a developer. Some (many) share the same developers, but there are still probably a lot more than Bitcoin.

So as I thought, the existing mining hardware would be very happy mining for any protocol that requires SHA-256d hashing.  This could be an entirely new protocol, completely separate from Bitcoin.

I think it is quite likely that there will be a Bitcoin "challanger" that arises from all of this block chain attention. 

My question still stands, are there any/many inherent flaws in the Bitcoin protocol that would provide a challenger protocol to be competitive?

And if so, do you think that any new protocols would attempt to retain backwards compatibility with the existing SHA-256d hashing hardware?


It all depends on what you define as a flaw. There are some features that Bitcoin doesn't have that altcoins do. There are some competitive altcoins out there, but Bitcoin still holds the highest market cap.

I highly doubt that they would continue to use SHA256d since the existing hardware can be bad during the beginning of that coin. Current ASIC hardware can mine a coin in its early days and push the difficulty incredibly high. That can immediately kill a coin if no one can mine on it. Also, that would lead to one of the potential flaws, mining centralization. SHA256d is easy to put into an ASIC so it becomes much more expensive to run mining rigs. A lot of people would prefer that everyone can mine using CPU or GPU and not ASICS since CPUs and GPUs are easier to get and much much cheaper.

I don't think an anonymous mixer can ever be legal in the US. Think about all the KYC regulations involving crypto exchanges and no profit tax paid on the profits.
I am fairly certain that all of the KYC and AML stuff in exchanges are for the fiat that they handle.
344  Bitcoin / Bitcoin Discussion / Re: How is bitcoin most important to you? on: December 22, 2015, 03:19:53 AM
Once I can amass a non trivial amount, I am going to use Bitcoin to buy stuff like computer hardware. I think I might even get a miner and try some mining.

How do othe hardware wallets compare to the trezor?

BTW, you have a few typos (keepkey/trezor mix ups).
347  Bitcoin / Bitcoin Discussion / Re: Why even use BitCoins? (read the post!) on: December 21, 2015, 03:47:53 AM
Bitcoin is secure, much more so than credit/debit cards. You are much more likely to get your credit card information stolen than you are to get Bitcoin stolen. With Bitcoin, there is no need to reveal your name or address. You don't reveal a credit card number so thieves can't steal your credit card and make your credit score tank. Credit card fraud is a huge problem and Bitcoin completely removes that.

Another thing, Bitcoin does provide a layer of anonymity. It is pseudonymous, so while yes people can trace your transactions, they don't actually know who you are. They don't have an identity associated with the address unless you choose to reveal it. There is no name or physical address to steal. Along with that, you can't get your identity stolen like you can with credit/debit cards.

Bitcoin is also a lot more convenient than credit cards or debit cards, especially to those who can't get those cards. If you have bad credit then you can't get a credit card. Bitcoin gets around that, it is like a debit card, but it doesn't have the problem that debit cards have, theft. Debit card numbers are easy to steal, and that can drain your entire bank account. Bitcoin doesn't have that problem.

Payments made through credit and debit cards are not instant. They do not instantly become reversible. Those transactions are reversible up to 180 days. With Bitcoin, it becomes irreversible after 10 minutes. Even if it takes longer, those transactions are still confirmed in less than 180 days. This is better for merchants than consumers.
348  Bitcoin / Bitcoin Technical Support / Re: Signing a message with a time stamp ? on: December 21, 2015, 03:39:46 AM
Can't you include the signed message in a small transaction?
That would ensure that there is a time stamp which can be verified (the time at which the transaction gets confirmed).
If you have some high priority coins lying around, you can send coins from one address to another. You may not even have to spend anything.
Transactions don't have timestamps. The only thing that indicates time in a transaction is the timestamp of the block that it was included in.

Also, to encode data in transactions to store in the blockchain is not trivial and to have all of it in one transaction would probably involve some coins being burned.

Did you tell them that you were going to be doing this kind of experimentation with your account? They might have banned you because your account was doing (in their eyes) sketchy stuff since you are experimenting and finding holes in their system. If you were malicious, then that could be really bad for them. They might have banned you if they did not know you were doing that.

Surely it's a state by state thing. I would've thought if you were in NY you'd have to have a bitlicence because you're handling customer coins even if there's zero fiat involved.

From Wikipedia

The regulations define virtual currency business activity as any one of the following types of activities:

receiving Virtual Currency for Transmission or Transmitting Virtual Currency, except where the transaction is undertaken for non-financial purposes and does not involve the transfer of more than a nominal amount of Virtual Currency,
storing, holding, or maintaining custody or control of Virtual Currency on behalf of others,
buying and selling Virtual Currency as a customer business,
performing Exchange Services as a customer business, or
controlling, administering, or issuing a Virtual Currency.

Hm. I suppose states would have some control, but I would imagine that there are also federal level regulations about this.

even without thinking about it I can guarantee you that number is below 1%.
Exactly. So why do we have to cater to that less than 1% of the newbies asking for loans? That number is practically zero. Why do we need to allow a bunch of newbies to fill up threads and that board with potential scams on the off chance that one of them is actually legit?
352  Other / Meta / Re: Petition to keep newbies outta the lending section on: December 21, 2015, 12:35:30 AM
But that *rarely* is enough to keep the newbies there. Just because the scammers are ruining it for everyone else (indicating the newbies) doesn't mean we have to block all the newbies out.
Someone should run some stats figure out how many newbies actually had valid collateral and actually paid back loans that they were given. If it came out to be statistically insignificant (e.g. <2% of all newbie loan requests were legit) then I'm sure that is enough reason to ban them from the section. Maybe I'll do this over the holidays.
353  Bitcoin / Mining / Re: Application of mining hardware to future blockchains. on: December 21, 2015, 12:31:59 AM
Is there any thing specific about the way ASIC miners handle work that is tightly tied to the Bitcoin protocol, as opposed to some other protocol implantation that uses SHA-256 and nonce based POW?  Aka, could some vastly different protocol with entirely different source code from Bitcoin still benefit from the established hashing power worldwide.
There is nothing specific about ASIC hardware that ties it to the protocol. However there is something specific that ties it to only be able to perform the SHA256d (SHA256 double) hash. The hardware is literally hard wired to only be able to perform a SHA256d hash function on whatever data it is fed.

Does the Bitcoin protocol REALLY lack that much at a fundamental level, or could it be added to and forked to retain supremacy?  Is there room for another protocol to do things differently and end up with a more adopted/useful blockchain?
First of all, the protocol is different from the consensus rules. The protocol is simply just the formatting of data and how it is transmitted. What people actually care about are the consensus rules, and those are what define what is valid and not. The consensus rules can be changed, protocol rules not really. Changing the consensus rules will typically involve a fork.

Do you think this is a likely scenario?  And if so, do you think the new protocol would be intentionally designed to be backwards compatible with existing mining gear, or would it be intentionally designed such that it required new mining hardware.
There are guaranteed to be changes to the consensus rule. Most of the BIPs involve some sort of change to those rules. The only thing that would require a change of mining gear is to change the algorithm used for mining. This would only happen if SHA256d was found to be unsafe and broken.

That is a good idea. How well is it working? Does it nicely heat up your rooms?
355  Bitcoin / Bitcoin Technical Support / Re: Signing a message with a time stamp ? on: December 21, 2015, 12:19:44 AM
What do you mean a "time stamp that could be verified" and "blockchain tech to protect author rights"? The blockchain doesn't use timestamps.

The easiest way to have a timestamp is to literally include the date and time in the signed message. It can be in any format, but it should also indicate the timezone in the timestamp.
356  Other / Meta / Re: Petition to keep newbies outta the lending section on: December 20, 2015, 11:54:08 PM
I support this.

Some newbs with valid collateral will still be there, and you'll lose a more or less valuable amount of potential members who turn away just because they couldn't access the Lending board.
Lets be honest here mate, admins won't bother.
Very few newbs have the valid collateral but i agree there are some that do but at the same time any project they might have can wait a month IMO
They could always just send you a pm if they want a loan and have valid collateral. If they do actually have valid collateral then you as the lender could post the details in the thread so that it is public.
357  Economy / Economics / Re: Transaction fee on: December 20, 2015, 11:51:19 PM
What are you talking about here and what you mean "unpredictable"  ? Fees are already low comparing to the other payment methods (0.0001 BTC = 0.05$) .

To pay from exchange it's 0.0005-0.001 BTC = $0.25-$0.5, for a rate of $5000/BTC it's $2.5-$5. Market rates could be manipulated and therefore the whole bitcoin game could be manipulated this way.
Fees aren't fixed forever, fees can change. If the price starts going up, then fees should start going down. You might end up paying the same value (purchasing power), just that the number displayed is different. So yes you could be paying a few dollars in fees if BTC was at $5000 but if those few dollars can only buy the same amount of stuff that the few cents we pay now, then there is practically no difference. It's called inflation.

I've tried using mellow ads but in order to use them, your site needs to be in the top 1 million sites in Alexa ranking, so my site didn't make the cut. Maybe yours will.

Is it legal to run a mixer in the US? How about in other countries? If you do run a mixer, what laws and regulations do you have to follow?

Is there any reward for doing an interview with you? It's ok if there isn't, just that some people might like some reward for their time. Anyways, I would like to participate, I will send you a PM.
