Hey, great site. But I did not find the block explorer. You should add a link.

Also seeing the "booooo!" bad shares problem on some machines after ~15 minutes -- not all machines, though, so very strange... the first one I setup is at 1+ hour no problem. One of the last ones I did started making 100% bad shares after ~15 minutes.

May have to revert my machines back to old 64-bit miner, sadly, if we cannot solve it.

if the miner lose it after 15 min ... then we need someone to make a bot that close the miner and reopen it each 15 min would be amazing

Do you have AMD or Intel CPU ?

The ones that seem to keep running for me are all Intel CPUs -- the one that quit after 15 minutes flat is a brand new 8-core AMD I just built.

yeah i have amd 8 core ...

great! So maybe we could discuss to write more about the algorithms. Just test read and copy paste. To write more about the algo would be unique under all the new altcoins...

Some information about hashing functions in qubit algorithm

1) Luffa

Luffa is a new family of hash functions submitted to NIST for their cryptographic hash algorithm competition.
Luffa is a variant of a sponge function proposed by Bertoni et al., whose security is based only on the randomness of the underlying permutation. Different from the original sponge, Luffa uses plural permutations in parallel and a stronger messsage injection function.

2) CubeHash

CubeHash is a cryptographic hash function submitted to the NIST hash function competition by Daniel J. Bernstein. CubaHash has a 128 byte state, uses wide pipe construction, and is ARX based. Message blocks are XORed into the initial bits of a 128-byte state, which then goes through an r-round bijective transformation between blocks. The initial NIST proposal ("Cubehash8/1") required about 200 cycles per byte. After clarifications from NIST, the author changed the proposal to Cubehash16/32, which "is approximately 16 times faster than CubeHash8/1, easily catching up to both SHA-256 and SHA-512 on the reference platform" while still maintaining a "comfortable security margin".
CubeHash advanced to the second round of the competition, but was not chosen as one of the 5 finalists.

3) SHAvite

SHAvite-3 is a secure and efficient hash function design by Eli Biham and Orr Dunkelman. SHAvite-3 is based on the HAIFA construction and the AES building blocks. SHAvite-3 uses a well understood set of primitives such as a Feistel block cipher which iterates a round function based on the AES round. SHAvite-3's compression functions are secure against cryptanalysis, while the selected mode of iteration offers maximal security against black box attacks on the hash function. SHAvite-3 is both fast and resource-efficient, making it suitable for a wide range of environments, ranging from 8-bit platforms to 64-bit platforms (and beyond).

4) SIMD

SIMD is a cryptographic hash function based on the Merkle–Damgård construction submitted to the NIST hash function competition by Gaëtan Leurent. It is one of fourteen entries to be accepted into round two of the competition, but was not shortlisted for the third and final round.
The designer states that the "most important component of SIMD is its message expansion, which is designed to give a high minimal distance". The algorithm's speed is claimed to be 11-13 cycles per byte.

5) Echo

ECHO, a cryptographic hash function designed for the NIST SHA-3 competition, offers:
- a simple and clean design,
- a high and well-understood security margin,
- support of the Intel AES instructions set, and
- a fully flexible design to support different properties with the same primitive.

try this version

and please give result of the test...
about version v1.1 can give info about cpu,os and ram pc where it is not working properly

[kahir]

will test and send results for 1.1A

Block reward halved.

i want to buy some before price rise because of the halving but my bitcoins locked in btc-e caz i changed password recently >.<




just a stupid question .... what if i try to mine q2c with my gpu and cgminer what will happen

I want to congratulate you on the completion of the first phase of our coins!
Thank you that you have support and actively participate in the development, first really fair coin!

This month we have achieved a lot:
- We have a website
- We have enough stock exchanges and a stable exchange rate
- We have stable pools (despite constant DDOS)
- We have new developers and very good designer
- We have high activity in social networks

The path is still long, but we are glad that you are with us!
- During the week we will update wallet
- Run a full poker room
- Make more games
- Run more pools
- new exchangers

Thank you!

P.S.
Unforgettable support the development of coins! Address and destination are listed on the main page of the topic!

By the way, why can't be Q2C mined with GPU? Just because there is no miner?

and try other pool... on my 3 pc i start receive rejects in the same time...

Ahaha, I'm losing logo competition I don't know, how, but at one time there appear more votes for another logo)

This coin will be more popular when it adds on cryptsy?

ofc ...but cryptsy is kinda picky .. i would say we will hit coined up or vircrus first ... or whatever the name of that exchange starts with V
