Myriad Skein Pool running stable
US Stratum is now LIVE. Also have an EU stratum.

Were finding blocks fast and always in the IRC to help miners

Running well on US servers, although SSL on the web page would be nice!

Sure if you want it, you can have it. I will install one by the weekend

Like above, i want implement things for my pool which people would use / or find useful. Would anyone here like/use a stratum server in Asia?

sold all my black coin and went into myriad..
I think we will be at 2k very soon..

Thanks a lot

I hope we will see a lot of nodes soon.

yeah me too. IMHO we need a skein node asap.

I have release the p2pool source code to setup a Myriadcoin qubit node on github:

https://github.com/linked67/p2pool-myrq

Let's start the revolution and make as many nodes as you wish, it's good for the network

Donations (myr) are welcome: MUHNPJvXCjCnQPeDFX2FnzWNN8C5tw9wak

PS: Don't forget to set the qubit algo in myriadcoin.conf

+2000 myr tip for you kind sir.

I've also patched Stratum against the diff-Attacks, No fake shares are counted.

Our Groestl Pool would need some power...

I'll lend you some 150 MH gro power. If Mike doesn't mind me helping other pools too

It also isn't clear to me how a node calculates the best chain. If it is cumulative difficulty, without any normalisation, then what is to stop someone reversing a sequence of low difficulty blocks (e.g. Scrypt or Qubit ones, currently) by means of a single high difficulty block (SHA256D, currently)?

The SHA difficulty is independent from the other algos, so a high difficulty SHA block will not overwrite a low difficulty Scrypt block for example.

Just in the last hour or so I've seen a chain of five non-SHA256D blocks (112715-112719) erased by a single SHA256D block (112715):

[code edited out]

How should this happen if they are truly independent?

anyone want to give this a technical explanation.. maybe a simple explanation too

Dev is only one that can atm

This is general block reorg (also known as a chain of orphans) it happens with a block time of 30 seconds. hell even with the 10 min block time of bitcoin it happens. In myriadcoin every algo has equal standing as each has an equal score. You can see in many POS/POW coins. POS orphans POW as POS has a higher score than its POW counterpart.

Ahmed

exactly! the coin is broken because a single SHA block can force a reorganization and orphan many blocks from other algos. This allows for easy double spending with minimal hashrate. Just mine SHA from the last SHA block ignoring blocks from other algos. When you mine your new SHA block, all the others will be orphaned. If there are enough to confirm a transaction (which is very likely), you can double spend.
But it can be fixed using normalization. Scrypt is about 1024 times SHA. You'd have to calculate the relative weight for other algos.

dev: you can contact me if you need help fixing this, I have experience with alt PoWs - I'm the developer of Riecoin (new primes PoW - currently cpu only)

Someone mentioned a bounty for a technical study on 51% attacks. Is that real? where can I learn about this bounty? what do you need exactly?
Besides fixing this "high diff algo reorganization attack", I have some ideas for preventing 51% attacks on a coin like this.

gatra

Thanks for your offer. PM sent. There is a 15,500 MYR bounty for analysis. I can also put up another 15K MYR for your assistance.

an idea to prevent panic:
there's an easy workaround (until a new client is released): when waiting for confirmations, wait for X blocks with SHA (the one with highest difficulty by far) instead of just waiting for X blocks.
So if you currently wait for 6 blocks, wait instead for 30 blocks and you should be safe ( 6 blocks * 5 algos = 30 blocks ). This would give you the same expected security in average.

1 thing is confusing me though. how can a person ignore blocks? ur forgetting that theres over 30 TH on the myriad network. it would take some real sha256 power to do any kind of attacks even on the sha algorithm

I'm less interested in the price and more interested in the increase in mining difficulty.

This coin was designed to solve the issue of distribution of mining for all and the price is helping drive that into action. Powerful network effect coming into play.

What is the expected daily mining rate going to be? Because at this rate the amount of new coins coming into the market is a lot.

The beautiful thing is that even if it is high, it's going into the hands of 5 different types of miners who may decide to do different things with the coin and bring them to different exchanges. Different demographics, which is another beautiful thing.

But right now there is plenty of buy support for the coin.

My P2pool should be OK now. Around 50Mh/s on it and estimated 3h to find a block.

You are all welcome on my powerful server

http://p2poolcoin.com:5567/static/

What algorithm?

Qubit, it's a qubit p2pool, the first !

I have some spike above 150Mh/s now. Join the pool, no need to register, just put your wallet address as username (-u wallet) and what you want in password (-p x).
