Another pool is down

One by one is leaving.

A list with active pools i know ...

Useful list, thanks.

Ever-curious, I followed the links ... these are each pool's own reported hash rate (at time of posting) and, where given, number of workers:

Code:

http://q2c.sytes.net:9372 - 5.98MH/s ??

http://qbt.mine-pool.net/ - 10.1MH/s ??

http://q2c.ext-pool.net/ - 1.13 Mh/s ??

http://q2c.mine-coin.de/static/ - 1.13MH/s ??

https://cpu-pool.net/qubit/ - 109.119 MH/s 36

https://www.mine-pool.net/qubit/ - 71.298 MH/s 55

http://67.207.208.166:9372 - 5.29MH/s ??

It's very limited in scope and the accuracy is highly dubious but I suspect that it's broadly indicative overall.

Cheers,

Graham

FYI

A little self-contained halving calendar in Python, checked with doctest. The dates refer to the START of each step.

The next per-block reward reduction (from 128 to 64 Q2C) will happen this coming Sunday - 27th. April 2014.

The per-block reward will drop to 32 Q2C on 18th. May and to 16 Q2C on 8th. June.

Code:

>>> from datetime import datetime, timedelta, date
>>> launchdate = datetime(2014, 1, 12)
>>> launchdate.isoformat()
'2014-01-12T00:00:00'
>>> halvener = timedelta(21)
>>> print(halvener)
21 days, 0:00:00
>>> ncoins = 0
>>> blockreward = 2048
>>> halving_every = 60480
>>> cnt = 0
>>> while blockreward > 1:
...     ncoins_this_step = blockreward * 60480
...     print((launchdate + (halvener * cnt)).date().isoformat(), blockreward, ncoins_this_step)
...     blockreward = max(0, int(blockreward / 2))
...     ncoins += ncoins_this_step
...     cnt += 1
2014-01-12 2048 123863040
2014-02-02 1024 61931520
2014-02-23 512 30965760
2014-03-16 256 15482880
2014-04-06 128 7741440
2014-04-27 64 3870720
2014-05-18 32 1935360
2014-06-08 16 967680
2014-06-29 8 483840
2014-07-20 4 241920
2014-08-10 2 120960
>>> ncoins
247605120

After the completion of the reducing steps, a 1 Q2C per-block reward pertains (with a target of 1 block per minute) for another 13 years.

Y'all might want to think about switching to an ASIC-friendly algo at some point, for when the per-block reward reduces to 1.

HTH

Cheers,

Graham

[gjhiggins]

I'm not the developer of this coin, but I think it deserves an update.

I hope you'll forgive a couple of technical queries:

1. What criteria did you use to arrive at the conclusion that the coin "deserves an update"?

2. With regards to adding a checkpoint, could you explain a bit more about the purpose of this proposed addition?

Cheers,

Graham

Any news about krecu?

His fan site http://qubitcoin.net/ seems to be down...

Thx for the halving dates!

The algo actually is ASIC friendly, as there are no random rounds of hashing afaik. If someone will make an ASIC in the future is another question.
QRK (ASIC unfriendly due to 3 of 9 hashing rounds using a random algo, not an unsolvable obstacle though, if you can make a miner you can build an ASIC) seems to do just fine without ASICS btw.

To answer your other question about the added checkpoint in willowrose's client, checkpoints ensure that a theoretical 51+% attack cannot reach too far into the past.

P2pool is 51% attack and DDos resistance.

The wallet has nothing to do with it.

Do you have file qubitcoin.conf in C:\Users\Your_account_name\AppData\Roaming\QubitCoin ?
If you don't have just create there qubitcoin.conf file and paste this:

Do you think that Qubitcoin has future on altcoin business ?

[baseke]

hakertajniak thanks a lot  man

You are right, decentralized p2pool mining offers some 51% resistance. However if a 51% attack succeeds (due to low p2pool hashrate, a whale with 5000 GPUs or a malicious pool etc.) checkpoints ensure that the attacker cannot reverse transactions/blocks beyond the last checkpoint.

Hi everyone can not synchronize my wallet. can anyone help me ?

I downloaded the mac wallet yesterday and it took a few hours for it to finally sync.

REVOLUTION TIME!

I got a message from willowtalk that this coin was neglected, but deserves some attention.

I was getting pretty irritated by all these great coins that lost the support of the developer, so I'm trying to start an independent foundation, the Coin Revival Foundation (CFA), that revives these coins and keeps advancing them.

My aim is to give altcoins back to the community and away from speculative whales!

Come to the topic to discuss this if you like and explain why QubitCoin would be a good coin to take into consideration.


Come and join!

VOting has started!

[peterlustig]

Still alive?

Difficulty back to 400 after a dip to 200 due to the block reward halvening on sunday.

@Jonesd: Qubitcoin is neither dead nor does it need to be revived.
