Added more features to the classes.
Extended examples, note that some of them may be slow to execute depending on your bandwith as some exchanges have hundreds of pairs.
To do
Add support for Poloniex, Krakken, Bitfinex

you can run a pruned bitcoin core, this way you will have the full functionnalities, and yes the BITCOIN RPC command is made to be used with bitcoin core.
All the exchanges use bitcoin core, and other daemons, yes they usually have the same API documentation, you can have more informations about this doing "./coinnamed help" it will list you all the available RPC commands.
When you use bitcoin core for an exchange or something using payment methods, you should use SSL, fetch the documentations and you will find all what i am talking about. For Altcoins, go to the source file and check the init.cpp in src folder, you will have all the list available.

It seems that bitdice is leading the way in being a secure platform since others are losing bitcoin to sercurity breaches lately. This does show a high level of customer information is a top priority to them and their team. Thank you bitdice for this!  Let me some time and i will tell you if it is secure or not, by the way, are there hack/bug bounties for the platform ? At the first look it looks like to be nicely coded, but i still hve to check all the requests. Had proceeded to a security audit of the system ? |

There is a pretty high demand at the moment for the network as people aren't really running full nodes anymore based on the simple fact that the network has so many transactions and you have to download the entire 100gb block-chain in order to do this. It's something that even if you believe in the bitcoin cause is kind of annoying to do these days.
The only way for people to want to do it, or feel any need to at least is for some sort of pay to be given or a percentage of the fees to be given to the people that use their own resources to make sure that these nodes are up and the bitcoin network is as secure as we all hope it is.
Maybe you can find some great ideas in the mastornode protocole, as you must invest some coins to be able to run it and get in return a reward based on the transactions you validated, it could give something interesting. You can't reward people for running a full node, they can take the reward and then delet the blockchain. So it must be done on the long run, i think this is why masternodes had been made. |

only just seen this ! I only host the pools as i do with quite a few alt coins i have nothing else to do with any coins appart from host them on my mining pool Don't worry, i totally understand, some people on the forum do supports these coins because there would be no other way to mine, or stake more expencive coins. The problem is just that it is annoying now, i am sure that sooner or later a new section in the forum will be created "Shitcoins announcements", it would be funny, but damn real. |

I like the idea of several games, they are all different and the offer is really amazing compared to other competitors, theUI is nice, simple, easy to understand and walthrough it, at least it is true for me.
But today the website is loading slowly for me, i have a good bandwith, unlimited, but it takes time to load background, maybe you should use smalle size backgrounds ? or with lower DPI.

I just had a look at the release notes, and i am really pleased by all the features i just found, you did a great job on this release, i am eager to test all the new implementations and changes.
Is it possible to have some examples of "-named" ? along with nested RPC commands ?
I awaited for a long time these features, and i am happy to see them in action, thank you.

Basically here the global schema for an exchange :
1- Daemons: Each coin traded must be backed by a fully synced daemon as he manages all the coins operations.
2- User interface : A use can ask for an address, this address is provided by the daemon, in an internal request.
3- Trade room: Usually, exchanges use an internal escrow for transactions as an amount of coins is held in exchange of annother coin, so they are escrowed internally, and when the price meets the users demande, funds are released to both parties.
4- Balances: They are managed by the server, there is a synchronisation between the database of the exchange, and the different daemons "accounts" RPC methods.
5- Withdrawals: they are operated at the request of the user, from his own account in the database, and in the daemon. If there are no funds in the daemon, the transaction won't be processed.
This is how an exchange works globally, now you can have several diffrences from an exchange to annother. The main difference is in the security level, Poloniex is known to be not so secure, if you have a look at your console when opening pages in poloniex, you will notice that every information sent or requested by the server, are using the 'GET' method, and this is prohibited especially when handling passwords and forms. They had been advised to revise these mechanisms, and to use 'POST' instead, but i don't think they did it.
The bitfinex hacking had something to do with this, they forgot to add a simple option to input text fields, coinables knows more about this then i, as he made a video explaining how the hacker managed to take the bitcoins.
I have knowledge of application security. I have an interest in the topics on OWASP. I can code the business processes of the project. But I do not know much about address generation and coin transfer. https://bitcointalk.org/index.php?topic=1796509.msg17921284#msg17921284the bitcoin RPC API documentation is your best friend, it is easy, just setup a script who will be triggered when a user demands an address, basically it will querry the daemon this way : bitcoin-cli getnewaddress [account] and for coin management, you will have to rely on bitcoin daemon basic implementation, which is : bitcoin-cli move <fromaccount> <toaccount> <amount> It is that easy, what i can advise you to do is not to think of it as beign too much complicated, satoshi and the bitcoin dev team made things easy, just make some scripts and test them, remember that you can always find a way to run a .sh script from webservers if needed, or you can do this using the RPC port instead, but you will have to use SSL ports as the data will be exposed, even if it is running in localhost, i advise you to use SSL. |

there are several problems here:
1.how to determine if it is a real node 1b. is it a full node or not?
2.how to make sure the owners are getting paid if they run one? automatic payouts (possible abuse) ,manual payouts after some checks
3.how to make sure your tokens keep value (are they being traded anywhere,how can you exchange them to bitcoins?)
4.how to inform potential node owners/already existing owners about your bounty etc.
Thus far i am still looking for a solution. Maybe i can help with some ideas : 1- This can be solved by attributing some special values to a full node, pruned node, spv node etc, maybe adding a detector in the daemon will solve this. i think about a solution like shadow cash did. 2- I would go for automatic payouts, with conditions, like time-locked transactions. 3- This will comme in time, maybe it would be good add a logic to the AI to reward based on a %value, something like that. 4- This is the most easy step, send some PMs to Arch, Hilariousandco, Lauda, gmaxell and others like LukeJr, they will be happy to know this. |

Good Morning,
in the forum post are a lot of private keys (i think so 10000 pieces).
the forum post is from January 2017, i have taken me one pk from the middle of the list.
And it worked,
i have now the money, and i donate 75% of this.
Thank you for your replies.
Best Regards!
EDIT: I donate 50% , i take me 25% and i will give the owner 25% back!
Wise men, giving 50% is better then nothing, can we know which projects you donated to ? |

Please consider donating to projects who supports the community, they really deserve this, and without them, bitcoin is nothing, and you wouldn't be able to exchange, trade, play, gamble ...

Hi,
i have found a wallet with 40 BTC.
The last transaction was 2011.
Can i take the money?
Or is it not legal?
Please Help!
Best Regards!
You found the keys to a car. Can you take the car? Is it legal? Don't be an idiot. The money is yours. It is not illegal to transfer bitcoin if you have the key to do it. Having the key means it is your bitcoin. Take it and transfer it to another address before another key holder does that. Not really, what i would do is to donate 39 BTC to people who needs it. Like donating to projects everyone use, but no one donates to, like UNOMP, BCOIN, and many others. I would keep 1 BTC as a reward for fair distributing the funds. But the question is, how did you found a private key in a forum, with 40BTC in the wallet ? normally as it is existing since 2011, it should have been aleready emptied. |

full blockchain, which is actually around 200GB.
Actually it is currently 111GB  [/quote] Yes, my mistake sorry, i just checked it : 112G .bitcoin I said around 200gb because it asked me at a moment for 180gb, maybe it was including other blockchains, thanks for the corrections. |

You can try to figure the date and adjust the number of blocks according to the first transaction issued. You could save a lot of DiscSpace. bitcoin 0.13.x is the latest bitcoin version, here is the download link provided by bitcointalk : https://bitcoin.org/en/downloadIf you want you can redownload the blockchain in a computer with more disk space, and then you can just send your wallet.dat to this new daemon/wallet, regardless if it is Mac, Win, Ubuntu, wallet.dat is an encrypted file, so it doesn't matter what OS is using it. |

The solution to the problem you are talking about is a global economical revolution, the prices are defined as :
-Demand: the higher it is, the higher the price will be.
-Offer: The higher it is, the lower the price will be.
Now there are several side factors that affects the prices drastically :
- Manufacturing unit position. (this is why it is cheap in India)
- Tax and customs policy.
- Licensing and development.
What is the effect of currencies on the prices :
- The impact of currencies have no real incidence on the price itself, in reality, it have no influance at all as the formula is (extended):
Suppose :
Product developed in India
Product manufactured in India
Raw materials produced in India
Company HQ in India
Customers in France, USA, GB, Germany, China, Japan
R&D cost (construction + research) + ManufacturingUnitsCost (construction costs if new) + Marketing = Global Development Costs
(RawMaterialPRice + ProductionCost) / ProductionQuantity = Manufacturing Cost
GlobalDevelopment Costs / Manufacturing Cost = Global PRoduction Cost
We apply a 30% profit margin Sellingprice = GlobalPRoductionCost * 1.3
Suppose :
Customs price in :
France 5%
USA 5%
GB 5%
Germany 5%
China 0%
Japan 0%
Export price = (SellingPrice (taxFree) + ShippingPrice) * 1.(CustomsRate)
Now here is the difference, plus the other Taxes locally like VAT.

PC - 2GB Ram, 23+Gb free diskspace
Ubuntu 12.10
Client
Bitcoin-QT
V.0.8.3.0-g40809ae-beta
I need to upgrade the client, and have had no luck. It is sync'd.
any suggestions? - I'll give tips to whoever moves this forward with me
backup wallet.dat, erase the blockchain and redownload bitcoin 13, run it using prune=50000 in bitcoin.conf I hope it is what you are looking for. Would that require me to re-download the whole blockchain (120+ Gbs)? I'm trying to avoid that. If that's the case, I'd just setup a new computer and import the wallet.dat. no, the solution i told you about will let you download the last 50k blocks instead of downloading the full blockchain, which is actually around 200GB. Go to bitcoin.conf and add : prune = x (where x is the number of last blocks you want to download)
This way, you won't have to think about blockchain size. I can only advise you to set an appropriate number of blocks, and avoid redeleting the blockchain after this because i don't know how the wallet will react if it finds a wallet with informations comming from old blocks not downloaded. You can finde more options here : https://en.bitcoin.it/wiki/Running_Bitcoin |

If i can figure out a way, i will incentivize users who run my wallet as a full node.
The problem with the full nodes is the disc space consumption, so even if you make people to run more nodes, they will only use pruned nodes, unless we find a webhost who offers cheap 300gb package. But it would be nice to have several blockchains starting from same application. Had you been able to test the system in a CLI environment ? or only using GUI ? I was running tests earlier today in a cli env, both SPV and full blocks mode seem to be syncing properly. Current work is resolving the wallet so it can display balances of all three coins. Interesting, so you can actually reward people with you coin for running full nodes, or maybe pruned nodes with a minimum amount of blocks, but i think it will require a heavy premine, or a system like nexus who manages a reserve used for rewards. There are many possibilities to reward people, but i think that you had a great idea there, it will for sure help to solve the lack of nodes issue. But how do you think you could actually rewrd people ? |

Yea, I also noticed.... had to verify the certificate to see if it was not a spoofed site again. I think displaying the total number of Bitcoin transactions,
instead of the active transactions, is a bad idea. I always send people to that site... to show them in real time, how transactions are being done and
then added to the Blockchain. It looked impressive, with the tx's flying by in real-time. {well close to it}
you can send them here : http://browser.bcoin.io/?network=main&prune=trueThey will be more impressed. |

I do not see major problems with DASH instamine. As I remember it was a community choice to leave everything as it was, though it was offered to start from the start and eliminate the instamine. But community decided to leave it, so now it is too late to complain about this. However, I don't know who runs Dash masternodes and this question is more important than instamine hype. Anyway, Dash looks like a solid market oriented project that has all chances to beat Paypal and even Western Union.
Correct. The Dash community decided long ago to move forward. Dash exists 3 years already and has lived through many periods of re-distribution. Only people stuck in the past are still using this instamine issue that took place in Dash very early time period, which is fine by me as it indicates they ran out of arguments against Dash. Edit : small piece of advice to OP, using a lot of red font tends to distract readers which leads to the message getting .. lost. You are right, big red text is harder to read, i droped reading as it causes too much damages to my eyes. I still don't understand why people are talking about Dash as like as it is one of these shitcoins, DASH is a well known, well established altcoin, monero also, but both of you are so much different that i wouldn't call you competitors. Dash is doing great in term of acceptance and growth, i am personnaly a fan of DASH, and i plan to run a masternode in the next few months. the full node is aleready running. Monero is doing great also, especially in market cap, the rise was amazing, i think on 1 year it earned around +3500% of price, which a nice achievement, i actually run a monero full node. Both of these coins are great but i still don't know why you continiue to attack Dash, please, let them do their job, and focus on your job, monero isn't that active regarding community, which is not the case of dash, think about it please. |
