481  Bitcoin / Development & Technical Discussion / Testnet difficulty and max target on: April 29, 2012, 08:54:02 PM
Hello,
I'm trying to import the testnet block chain on a library I'm working on but speaking of difficulty I'm not understanding well the differences relative to the production network.

This is what I've understood until now about prodnet:
- max allowed target is 0xFFFF0000000000000000000000000000000000000000000000000000
- corresponding max bits (compressed target) is 0x1D00FFFF

While in testnet:
- what is the max allowed target?
On the wiki it's stated that "Minimum difficulty of 1.0 on testnet is equal to difficulty of 0.5 on mainnet. This means that the mainnet-equivalent of any testnet difficulty is half the testnet difficulty." so I guess I've to shift left the prodnet max target, getting 0x1FFFE00000000000000000000000000000000000000000000000000000 but I can't find any confirmation for that.

- what is the corresponding compressed target?

Any help would be greatly appreciated!

Haha, bitten by the "usual" problem of a non thread safe data structure...

Use Collections.synchronizedList(new ArrayList(...)) to create a thread safe arraylist ;-)

Bringing bitcoins to games is totally awesome, while trying to use their graphic card to mine is probably a waste by the time this kind of project will operative...

Are you saying we should not trust any other clients other than open source at all?
No, I didn't: where have you read this?

Some solution gives you more control, some less: only open source software gives you complete and total control.

You choose which one is suitable for you in relation of the amount of money you have to handle, and having more options too choose from it's usually better.

If this thread prompts too many people to contact them in a short period of time, it will look like spam.
Judging from the number of views and replies of this thread, they probably will not even notice as relevant the requests...
Too bad.

He is citing as "disadvantages" the following:
 "You have to trust the provider not to be careless or malicious" Isn't it true of just ANY third party provider ?
When I am using the bitcoin client I am trusting the developers to be  not malicious nor careless.
With open source software you have the option to download the sources, check and compile them by yourself (or doing so using the services offered by a third party if you prefer).

So, if you want, you can be 100% sure there is no malicious code and you do not have to trust the developers or anybody else.

With services offered via a web site you can't: you always need to trust someone else not chosen by you.

And that's not an negligible difference, if you ask me.

Nice job on taking the initiative.
Would you care to post your email here?
I prefer not, otherwise ppl copy it, and I find it better that they get all different requests Smiley

Anyway, I really can't understand why they behave this way, btcs seems so right for their kind of business.

A new Humble Bundle is offered, where you can buy a bunch of games for the price of your choice, even 0.1$.

But they do not accept bitcoin payments, that's really a shame!

I wrote them to contact@humblebundle.com and the person replied that he will send the suggestion to the team to evaluate the possibility: I suppose that if more of us ask for that thing we could have a higher probability of success.

So... make your voice be heard  Cheesy

I'm unable to browse spendbitcoins.com with firefox, I get this error:
Code:
Secure Connection Failed
     
An error occurred during a connection to www.spendbitcoins.com.

Peer does not recognize and trust the CA that issued your certificate.

(Error code: ssl_error_unknown_ca_alert)
while I get an error of untrusted connection while trying to browse https://au.spendbitcoins.com/

Using chrome it's ok for https://spendbitcoins.com/ but I get the same error on the au site

Io leggo regolarmente ma i troppi impegni lavorativi e familiari dubito che mi permetteranno mai di partecipare.
Per ora mi limito a lurkare :-)

Not possible with the state of exit nodes today.
Maybe it's possible to do it via I2P since it's a bit more efficient (it's designed for these kind of things).

BTW, I wonder why silk road uses tor and not I2P.

And pray tell, which new site is this?
I dind't say there was a site doing it.

But usually demand drives offer, so, if GPU mining will be still relevant in the near future (thing I doubt) I bet someone will pop up with decent and useful benchmarking.

Of course that is all utterly ridiculous and stupid, but that is the reasoning they use.
That's fine, they'll lose users to a new site that will do serious mining benchmark  Wink
