2  Alternate cryptocurrencies / Altcoin Discussion / [ANN] Yacoin Mining Still The Most Profitable! on: December 02, 2013, 08:31:36 PM
Many Scrypt coins are dominated by FPGA miners. Feeling sad? No more! Yacoin is THE coin for you!

FPGA mining non-existent, GPU mining becomes less and less profitable each Nfactor change. Now you can finally put that CPU of yours to a good use! Also, only a few people mine Yacoins, so there's really small competition and quite high rewards!

With exchange rate of YAC skyrocketing in the past days, the profitability is over 1000% of Litecoin (depends on your hardware, though). Mind you, the most profitable vanilla Scrypt coin has only 350% profitability of LTC. Yes, the numbers are right.

There's a mining profitability calculator where you can check your daily earnings in YAC, LTC and BTC if you know your hashrate for each of t hese coins/algorithms. The hashrate ratio between YAC and LTC can vary significantly due to CPU cache size and/or GPU local memory size. You can expect 1/60 to 1/70 of your LTC hashrate as a "rule of thumb" (at least for CPUs - as that's what this coin is meant for) if you don't want to benchmark your hashrates first.

We also have a wiki page with mining hardware comparison at http://yacoinwiki.tk/index.php/Mining_Hardware_Comparison (yes, it's quite slim at the moment - feel free to add your own hw and hashrates).

For example, with one of the CPUs listed on wiki, you can get 0.3 kh/s with YAC and around 18 kh/s with LTC (giving a ratio of 60). Plugging these numbers into the calculator yields:
Quote
YAC/LTC profitability: 1149.38%

YAC Mined per day: 20.33 YAC / 0.00365962 BTC / 3.94 USD
LTC Mined per day: 0.01 LTC / 0.0003184 BTC / 0.34 USD

Cool, huh? Wink

Come joins us at http://yacointalk.com/index.php/board,4.0.html for info on how to start mining, a list of pools and assistance from a helpful community!
3  Bitcoin / Project Development / Kindle 4NT Bitcoin Dashboard! ┗(0)┛ on: November 15, 2013, 02:37:58 PM
So after a few inspirational posts on /r/Bitcoin with photos of Pebble smart watch showing the current Bitcoin value, I've decided to hack something for my Kindle 4 Non-Touch. Wink And here's the result! Using the bitcoincharts.com charts and MtGox ticker API. All the code is available on Github, along with a how-to for setting it up. https://github.com/saironiq/kindle-to-the-moon

4  Alternate cryptocurrencies / Altcoin Discussion / [ANN][YAC] Coin Control for YaCoin is here! First altcoin with Coin Control! on: August 18, 2013, 09:36:11 AM
================================
EDIT: NEW UPDATE 2013-12-09:
New windows binaries released, updating requires user intervention!


You NEED to move/rename (backup) everything except wallet.dat and peers.dat in the yacoin data directory and then run yacoin with -loadblock=C:\blk0001.dat (assuming you put the blk0001.dat file in C:\). This is needed because we had to change the way blocks are indexed and now the wallet starts in LESS THAN 30 SECONDS (down from more than 30 minutes). However, this initial load will take somewhere around 2 hours (still faster than downloading it through the p2p network).

If you don't mind redownloading all the blocks, you can just remove the unneeded files and start yacoin normally (less hassle, but takes more time).

Most of the time at startup is now spend verifying the last couple of blocks (which needs to to recompute their hashes to ensure integrity). I've lowered this number from the default 2500 to 666 (rather arbitrarily chosen, but should absolutely be set higher than 520).
================================


Announcing YaCoin-Qt client with Coin Control features!

YaCoin - The FIRST AltCoin with Coin Control!

Do you wanna:
  • send specific Unspent Outputs but the Qt client keeps choosing them randomly?
  • have control over your Anonymity? (Well, pseudonymity, to be precise.)
  • have control over your Coin Age?
  • maximize your Proof of Stake rewards?
  • choose the Change Address yourself?
  • know the Transaction Fees associated with your transaction before attempting to send it?
  • see the Transaction Priority of your transaction?

Then Coin Control is just the thing for you!

NOTE: Enable in Settings -> Options -> Display, check "Display coin control features (experts only!)". Aaaand it's done. Enjoy. Wink


Disclaimer: Don't download anything if you don't trust me. Do your homework. Review the github repo code commits. Compile it yourself.

Compiling for Linux:
Code:
git clone https://github.com/saironiq/yacoin-cc.git
cd yacoin-cc/src
make -f makefile.unix
cd ..
qmake
make

Compiling for Windoze:

5  Alternate cryptocurrencies / Altcoin Discussion / [ANN][YAC] Yacoin Network Graphs! on: May 30, 2013, 06:10:59 PM
Hi!

Finally managed to fix server, so I created something new:
Yacoin Network Graphs! Plotted from fresh block explorer data at http://explorer.yacoin.org, updated every hour. Includes difficulty, network hashrate and block interval. All time and last 24 hours (1440 blocks). Tips and suggestions appreciated. Wink

Here they are, have fun!

Hi!

I've developed a tool in Python that lets you manage large amounts of Bitcoin addresses/private keys along with seeing their cummulative balance. Includes batch address generator, which is also usable as a private key bruteforcer if you think you're lucky (hence the name, LOL). Tips and suggestions welcome.

9  Other / Beginners & Help / [YAC] cpuminer slower than yacoind? on: May 10, 2013, 09:35:54 AM
Hi!

I've had about 150kh/s in stock yacoin wallet miner (Linux, compiled with all native optimizations enabled). This hashrate varied greatly when blocks were switched every <10 seconds, but this was expected (almost never below 60kh/s, however).

Now that we have pool, I decided to try cpuminer, but it hashes only at ~24kh/s (~6kh/s per thread), also compiled with all optimizations.

Anybody got some idea why?
