Bitcoin Forum

Hi guys!
The website is online for quite a while now, but wasn't really stable. It's now ready for its grand opening! I'm very excited to share it with you, there is a LOT of features that aren't available ANYWHERE else.
Base URL: http://coinplorer.com

Main features:

- Most advanced profit simulator so far (http://coinplorer.com/Hardware/Simulate). You can add YOUR hardware to the list and have ROI for each of them. Different difficulty extrapolation algorithms are supported (linear, flat, exponential or manual input, feel free to propose more). You can simulate profits in BTC of course, but also in all other currencies we support. You can save and share the simulations even if you don't have an account (but it's better if you have one :) -- 3 auth methods to retrieve your saved simulations: url key, cookie key (go to hardware > create or retrieve a simulation to get the list of your previously saved simulations) and account.

- Multi currency block explorer; importation progresses can be found on http://coinplorer.com/Console/Status2 (I heavily rely on the official daemons of each currency to import the blockchains and I can guarantee you some of them are a real pain in the *** and none of them is really fast or stable! => for example, the worst are BTCT (VERY slow, crashes a lot, I guess because people are doing experiments on it), XPM (sooooooo slow!), FRC and ANC (crashes all the time)):
Anoncoin ANC
BBQCoin BQC
BitBar BTB
Bitcoin BTC
Bitcoin Testnet BTCT
Bytecoin BTE
CHNCoin CNC
CryptogenicBullion CGB
DigitalCoin DGC
FeatherCoin FTC
Franko FRK
Freicoin FRC
JunkCoin JKC
Litecoin LTC
Megacoin MEC
Mincoin MNC
NovaCoin NVC
Phenixcoin PXC
Primecoin XPM
Terracoin TRC
Worldcoin WDC
YACoin YAC
NMC, PPC, DVC, IXC not supported because of their clients (see http://coinplorer.com/Pages/FAQ).
Some currencies have better support than others as I rely on their clients (some doesn't even tell the vout addresses or even the vin txid! If those currencies ever get their clients corrected the importations will automatically be corrected).
NB: If the status page fails to load some currencies or is very slow to load some currency, it means their client is faulty (they are ALL hosted on the same server, running the exact same way, and the server is far from being overloaded).
The BTC client is probably the more reliable, even if I'm running 12 (!) clients simultaneously to make it able to import all transactions of blocks within an acceptable timeframe.

- Multi currency exchange rates charts here (http://coinplorer.com/Charts/BTC/USD): you can basically graph any currency in any other (from the simplest, aka BTC in USD, to the most complicated, for example CGB in AUD or even petroleum price in BTC -- exotic graph loading might take a few seconds (because of cache warm up), just wait ^^). I had no success displaying this on the charts, but everywhere an exchange rate is displayed, placing your mouse over will show you how it's computed after a few ms of wait.

- Difficulty charts and predictions (http://coinplorer.com/Charts/Difficulty/BTC), with a very nice look (you can feel it much better on a chart than with just numbers)

- Mining hardware comparison (http://coinplorer.com/Hardware), a classic (I needed a list for the profit simulator)

- Currencies profit comparison (http://coinplorer.com/Hardware/CurrenciesComparison), a classic too (given the base I had, it was "free" to do). I wasn't able to properly distinguish "miners rewards" from "foundation donations" on FRC, leading to a wrong calculation for FRC (divide the profitability of it by ~3 currently). If anyone have an idea on how to distinguish rewards from donations GENERALLY SPEAKING (I don't want any currency specific code), just let me know!

- Discussions (http://coinplorer.com/Discussions) which are a mix between a forum and a chat (each topic can be seen as a channel). This is very basic for the moment, but will improve over time.


Coming soon: maybe a donation widget and/or an exchange rate widget.
Coming a little bit later: portfolio manager (input your addresses and it will tell you how much you own in any currency), mining rig manager (watch your speed, change the settings of your workers, alerts, etc.), API.



How it works:
- Full blockchains are imported into a MongoDB datastore, with very little changes from the clients outputs (only normalizations of the outputs + denormalization of some parts of the data to speed up some queries)
- There is a "watchdog" that reboot the currencies server when some of the clients are down or irresponsive (because stopping the clients via RPC just doesn't work most of the time when clients stop responding... I found a reboot to be easier than killing the faulty clients)
- The importer always look for inconsistencies in the imported things with a full check every week (friday nights).
- Exchange rates are retrieved from the major exchanges (Mtgox, Bistamp, BTC-E, BTER, Cryptsy, The Rock Trading, Vircurex, Coinchoose, Bitcoincharts, European central bank and OpenExchangerates (the latter 2 to have fiat currencies exchange rates) and combined together (an exchange rate object is currently more than 8 500 combinations of currencies!)


Interrested in the project?
Participate on the discussions threads :) I'm always looking for moderators, admins, etc.!

I gladly welcome any bug report or feature request.

Disclaimer:
Do NOT rely on the provided data, it can always have a bug somewhere! I'm very dependent from outputs of the clients and how MongoDB want to works (sometimes it's very lazy!).
Despite more stable now, it's still in an early beta stage.

Damn, I wonder if I posted this in the good forum...

Cool website! I like it! Have you through about replacing the front page forum with a chat box?

Thx. Why not, good idea,  even if the chat box is already embedded in all pages.

Updated: simulations charting (now consistent across the website), ability to enable/disable pieces of hardware in one click.
Next: diff prediction, then direct input for simulations difficulties

Completed difficulty prediction, pretty satisfied by the result: http://coinplorer.com/Charts/Difficulty/BTC (http://coinplorer.com/Charts/Difficulty/BTC)

Would be cool to have a listing of the latest crypto news stories.

You use Mt.Gox to convert BTC to USD? Come on. Please use BitCoinAverage or something like that.
Nobody will give you $180 when the average price is $162.

I'm not asking anybody to give me $180. The data only needs to be consistent across the days. I choose mtgox as the reference because they still (unfortunately) have 50% of the total traded volume.
If you put your mouse over a price it will tell you how it's calculated (doesn't work on charts though).
In the simulations you can input the exchange rate you want (people usually simulate with the current exchange rate to calculate their ROI, but the exchange rate will NOT be the same when you'll sell your BTC).

I just completed the "manual input" for the difficulty extrapolation. You basically input the date and value of the changes and that's it!

Nice website.

thanks :)

Just pushed up a nice update to the difficulty prediction, have a look: http://coinplorer.com/Charts/Difficulty/BTC

nice website and awesome graphs. Looking forward to use this in the future

Thanks. I just finished completely rewriting the difficulty charts and predictions (see http://coinplorer.com/Charts/Difficulty/BTC (http://coinplorer.com/Charts/Difficulty/BTC)), for the second time.
Predictions are now very accurate and I even display the hash power extrapolation I use for difficulty prediction.
You can even play with the "Average hash power over" input to see it changing (to have more accuracy, <=4 days is averaged to 4 days for prediction and >=14 days is averaged to 14 days).
Difficulty changed today :( so the next prediction might not be hyper reliable yet, but I believe it's the most reliable out there.

wheres mastercoin dude??????

It's listed in "purgatory" on https://bitcointalk.org/index.php?topic=134179.0
(there is also some currency listed in the purgatory that I support, but it was because there were in Minor or Candidated when I added them).
"MST MasterCoin- premined LTC clone"

No wrong mastercoin, check my signature

OK, sorry, "-MSC mastercoin- Not launchet yet, but you can buy them already. coins created by buying them with bitcoins. operates on a bitcoin blockchain.".
I can add it if it satisfies the requirements:

We choose to heavily rely on coin's clients: this enables us to potentially support ANY bitcoin-like cryptocurrency, even if their internal algorithms or exchanges are totally different.

We basically uses those clients as an "API" to providing an access to their blockchains objects. Those clients can be of any kind, as soon as they provides an RPC interface.

The only required conditions are:

If the daemon runs in our servers, it must be able to run under Linux Debian x64, be open sourced and have its source code hosted on a git repository (so we can update it easily)
The daemon supports getblockcount (returning the number of blocks in the chain)
The daemon provides a way to get a block by height (either direct, for example getblockbyheight or indirect, for example getblockhash then getblock)
The daemon provides a way to get any non wallet transaction by txid (either direct, for example gettransaction or indirect, for example getrawtransaction then decoderawtransaction). If those details are included in the blocks, it could be fine too.
The JSON outputs are similar to the outputs of the official bitcoind daemon

Great website.

As far as FRC goes--

* To remove the foundation coins from the number of coins issued per block, subtract 496.03174604. There will be no more foundation coin issued after block 161280.

* There's some problem with the FRC price data. On some of the graphs you have FRC is $20,00,000 per coin.

This is not "currency independent" + the number of coins going to the foundation is supposed to evolved isn't?
Beside this, I've always seen those "foundation coins" as a form of premined coins...

Thanks for the bug report! It seems like Vircurex returns bullshit for the low price sometimes... I manually fixed it for the latest FRC-USD rates + added a new filter to prevent this in the future, but I'll add to "reprocess" the past to definitively get rid of the wrong points. I'll probably do this tomorrow or the day after.

The foundation is awarded 496.03174604 coins per block. You asked "in general" how to remove the foundation coins from your calculations. This is how you do it.  The distribution to the foundation ends at block 161280. Up until block 161280, the reward to the miner is not constant.

Rather than defend against your "premined" comment I will let this website speak for the foundation. (http://foundation.herokuapp.com/)



Thanks for looking into this bug.

nice work!

Have to say your signature is really annoying, too shining.

sry for ot: how can i get my sig to become MORE shining ?

Totally agree :) But well it takes what it takes :D I would only change this if required by forum rules.

This is getting interresting, but totally off topic. Premined coins that goes to a foundation are still premined coins. And the foundation is a total joke (see http://foundation.herokuapp.com/#/donations (http://foundation.herokuapp.com/#/donations): 3 organizations including themselves!). And as I understand, you donate to them and the foundation add "+10%" to the amounts you donate (seriously? you donate with the 20% you receive for mining, they receive 80% and they only add a shameful 10%?!) "The Freicoin Foundation will add an extra 10% to the freicoins you donate to the non-profit you've chosen.". But again, totally off topic.

I corrected the bug :)

the only thing really missing is an api ..
most important api call would be to get the balance of an address (for different alt-coins) ... no other side can do this yet!

I'd like to have a "private API", where I can choose which service could have access to it.
Having it open would incur only bad things:
- Potentially less visitors
- More load
- No more revenues

If you have an idea of service backed by my API, let me know!

I added:
- Megacoin (MEC) support -- currently importing
- Manual input for difficulty estimations in the simulator with copy/paste support and a sample spreasheet

I love Coinplorer!

One of the best devs I have worked with, fast and efficient!

Obviously capable to see this site reach top ranks. It's my favourite blockchain explorer and it's only young, I look forward to seeing this go places  ;D

Love the site man! Good work, ty for adding FRK!

great site

thankyou

Thanks guys!
I've also added a "mining profitability" chart yesterday, see http://coinplorer.com/Charts/PriceDifficulty?fromCurrency=BTC&toCurrency=USD (http://coinplorer.com/Charts/PriceDifficulty?fromCurrency=BTC&toCurrency=USD)
The formula is MiningProfit(Date) = ExchangeRate(Date,BTC-USD) * AvgDifficulty(Date,USD) / AvgDifficulty(Date,BTC)
It also shows the potential correlation between difficulty and price (at constant hardware) or, if you compare 2 crypto currencies, if it's better or not to mine one to get the other (example: LTC/BTC => if line goes up, it gets better to mine LTC to change them into BTC).
The chart is full of information, but pretty hard to interpret.
