Is there a minimum required amount of Bitcoin in an address to post a signed statement in this thread?

What do you mean by integrate? Do you just mean install. If so, then you need a webserver software like apache and just put all of those php files in the document root.

Just wait. Bitcoin Core has not fully synced with the network yet. You need to wait for that green bar to go away and a little green checkmark to show up in the corner of the window. Your balance says 0 since the wallet has not synced yet and does not know about that transaction. Don't worry, your Bitcoin is still safe as long as you don't do anything stupid like delete the wallet. You are close, it is only 15 weeks behind. Just wait a little more and everything should sync up.

Just to be sure, you can check a block explorer like blockchain.info or blockr.io to check that the Bitcoin actually made it to that address.

9484  Bitcoin / Development & Technical Discussion / Re: On a technical level, what determines how big a block will be? on: August 16, 2015, 12:44:39 PM
The transactions included are determined usually by their priority, which is also determined by the fee. Large transactions are typically high priority as well as transactions with a decent fee. I think the software will pull the transactions with a high enough priority first and include those in the block. Also, part of the block is a thing called the merkle root, which is a hash of all of the transactions included into the block. In order to change the hash in different ways besides the nonce, different transactions will also be included to change the merkle root. Generally, block sizes are determined by how quickly the miners exhaust nonces and how many transactions with decent fees can be stuffed in.

So does the amount of transactions in the block change with each hash attempt with a new nonce?
The amount probably changes a little when the range of nonces and extranonces is exhausted since transactions are different sizes. The transactions inside will probably change as something needs to be changed in order to get something different for the hash. I think lower priority transactions (low fee) will be removed in favor of higher priority (high fee) transactions.

Even if he didn't he should know that everyone here will want him to sign a message. He has a PGP key and several Bitcoin addresses that are known to be owned by him. Just by reading any of the "I am Satoshi" threads around and the posts in this thread and other threads as well as replies to the mailing list, Satoshi should know that in order to be taken seriously as Satoshi, he must sign something saying that that was him.
9487  Bitcoin / Bitcoin Discussion / Re: Satoshi Speaks. Real? Hoax? on: August 16, 2015, 11:25:58 AM
and if this fake who is using this email in a secret mail provider that not anyone can have access to it?
You can get access to it. It is one of the domains used by anonymousspeech.com, an anonymous email provider. When you sign up there, there is the option of selecting a vistomail.com email address. So it isn't a secret mail provider.
9488  Bitcoin / Bitcoin Discussion / Re: Thoughts regarding "satoshis" post today on the mailing list? on: August 15, 2015, 09:51:58 PM
The email that sent that email has been used by satoshi before in the early days of bitcoin. You can see it in the masking list archives.
9489  Bitcoin / Bitcoin Discussion / Re: Satoshi Speaks. Real? Hoax? on: August 15, 2015, 09:44:13 PM
It might be him since that email was used before.

BTW, there is already a thread about this here: https://bitcointalk.org/index.php?topic=1153708.0

If you have a text file with all of the private keys in them, you can use a shell script to iterate through the file and import each key.
9491  Other / Off-topic / Re: How to encrypt a puzzle on: August 15, 2015, 06:49:07 PM
Hi,

Letīs say I have a puzzle. I want to publish the solution online at the same time I present the puzzle to the public, but the solution should be encrypted.

How can I do this is practical terms? I want to prove that the results of the puzzle were uploaded and untouched, only protected by a key. Therefore impossible to manipulate.

The key would be given out to the public in the future to prove the solution.

Thanks

Hash the solution if possible and provide the hash. It allows users to check whether their solution is correct. It does allow for a brute force attack on the hash, but depending on the complexity of the solution that should be no problem.

Yeah, how does one do such thing?

E.g. here -> http://www.xorbin.com/tools/sha256-hash-calculator

Enter your solution as "data", click Calculate... and publish the hash.

E.g.:
I hashed (sha256 using the above site) a number between 1 and 10, this is the hash 6b86b273ff34fce19d6b804eff5a3f5747ada4eaa22f1d49c01e52ddb7875b4b
which number was it?

Sounds more complicated that I thought. No idea what the number is.
That's the idea. You can't know from the hash what was hashed, but when you have an answer, you can easily check to see if the answer is right.
9492  Bitcoin / Bitcoin Discussion / Re: What's the best documentation to convince a merchant to start taking Bitcoin? on: August 14, 2015, 08:04:30 PM
You can get them added to various maps of places that accept bitcoin like coinmap.org

The biggest processors are BitPay and Coinbase, but I don't know if they have in store stuff. They should have decent documentation.

Also, where is this shop? If it's near me I might stop by and buy with bitcoin.
9493  Bitcoin / Development & Technical Discussion / Re: How would you prove that you own >= X BTC without disclosing addresses ? (ZKP) on: August 14, 2015, 07:38:34 PM
I don't think that our is possible without telling people what addresses are yours.

You could sign a message with the private key of an address that holds ≥ x BTC, and then distribute the bitcoins over a tree of other addresses or mix them.
That would only price that you had x btc at one point in time. It didn't guarantee that the bottom sent to other addresses are still in your possession.
9494  Bitcoin / Project Development / Re: [BOUNTY] fix mobile WLCj wallet for android on: August 14, 2015, 07:30:26 PM
I have looked at the code and it looks like that the coinj you forked does not have support for merge mining. I would suggest that you fork the java library for something that does support merged mining.

The latest code is a fork of namecoinj and does support merged mining, in theory. It is failing in practice at the moment.
It is? The repository linked above is still forked from freicoinj, nor namecoinj. Is there another repository.I could help if I knew what the code is and what coin wlc itself is forked from.

9496  Bitcoin / Project Development / Re: Bitcointalk Account price estimator on: August 14, 2015, 06:59:36 PM
When I use my userID into the estimator I got this:
Quote
User Id: 15713
Name: brunoshady
Posts: 252
Activity: 182
Potential Activity: 168
Post Quality: Poor
Trust: Negative, Red Trust
Estimated Price: 0.01919531
Why is my potential activity 168 while my actual activity is 182?
That seems to be a bug. I am trying to fix the biu but I don't have the time right now and it is a little hard to find. I'm working on it.

Thanks. Your site is working. Gave me not a bad estimate for my account.  Cheesy

I have a suggestion. It would be nice if your estimator can show the username and simple info of the account after entering the uid. Then users click a button to start the calculation. If someone enter the wrong uid, they might have to wait a long time before they know it, wasting time querying the forum database again.
Thanks. I will take your suggestion and see if i can include it into the next version.

tiny suggestions:
* 0.13991250 btc   instead of 0.13991250
* translate to usd & euro & yuan
* Date registered, ages in days
* Last active
* newbie / hero / ... / half-god
I will take some of your suggestions and include the BTC unit as well as some other account info. I won't have the firat conversion though.

.
No time to look into your code.  Are you actually also parsing all my posts pages?
If yes: ... then you could extract all the links from the header of each post e.g.
https://bitcointalk.org/index.php?topic=1147294.msg12086244#msg12086244
and extract all the "topic=1147294" parts, adding them all to a list.
When making that list unique, the length will give you
in how many different threads I have been posting.

len(  list(set(  topicsList   )  )  )


-> easy to distinguish different "types" of users

Not sure how to relate that to a price, but it would be a cool extra info.


It does go through all of the show posts pages but what would that really accomplish?

Looks like you have a problem with the wallet file. If you don't have any bitcoin one it yet and haven't given out any addresses from it, then just delete the file and you will get a new wallet. Otherwise, you will need to use the salvagewallet command.
9498  Bitcoin / Bitcoin Technical Support / Re: "fatal internal error" while syncing on: August 14, 2015, 06:48:40 PM
It looks like you have a database error. Just reindex the database and that should fix the problem.
9499  Bitcoin / Project Development / Re: Bitcointalk Account price estimator on: August 13, 2015, 04:24:49 PM
Just one question - Why is the estimated activity lower than the current activity? I expected this to be higher as I've been posting quite a bit over the past week.
Not sure, must be a bug. I will check it out.
9500  Bitcoin / Project Development / Re: Bitcointalk Account price estimator on: August 13, 2015, 03:31:15 PM
It looks like that I have some problems with the queue. I'm going write a quick fix that makes the wait time to be 10 minutes instead of 5. I will also have to restart the server which will also clear the queue. I will edit this post when I go to restart it.

I will be restarting the server now. The queue will be cleared and the wait time has been increased to be 10 minutes between requests.

I will be working on another fix that will require a payment for the 3rd or above request in an hour. E.g. after 3 requests, the next request will require a payment (as long as it is requested within an hour of the first.)
