Just a dirty example in pseudo-code:

Code:

PoWHash(Data):
   laFunctions = [Skein, scrypt_pbkdf2_salsa, scrypt_keccak_chacha, Groestl, Keccak, SHA512, Blake]
   liFuncIndex = 3
   lsHash = Data

   lI = 0

   while lI < 5:
   if liFuncIndex < 0 or liFuncIndex > len(laFunctions):
   liFuncIndex = 3

   lsHash = laFunctions [liFuncIndex](lsHash)

   if (lsHash[64]&(1<<0))!=0:
   liFuncIndex = liFuncIndex - 1
   else:
   liFuncIndex = liFuncIndex + 1
   lI = lI + 1

   return lsHash

But it's potentially vulnerable to lsHash[64]&(1<<0) brute-forcing. This could be resolved by adding more conditions to make it stronger.

why, what was the point if 6 algorithms, why not 7 or 5. What is your purpose other than adding complexity to a solution that is already exists (scrypt)?

just like that Wink

long chain complicates gpu optimization thousands of times, there is a function not so accelerated, and it will slow down the entire chain functions.
Unfortunately, i no have knowledge of mathe, pre-select in this regard "good" algorithms.

i will pay 75 SIC for first pool and 75 SIC for miner on cpu..

I will add 10 sic to each of those

Does the client have possibility to look on generation speed? Both per machine and whole network

I thought satoshi is just for BTC?

Why not? good, the traditional name for the atomic unit cryptocurrency.

Based on code Bitcoin 0.8.2

Start: 2013-06-23, 00:00 GMT

Coin: infinity in time

Block target: 5 minutes

Dif retarget: every block, +-1% of mean last hour

1 Coin = 100'000 Satoshi

Block reward = 1Coin + bonus
bonus = sqrt(Diff * block#) Satoshi (eq 0 in start, hundreds in far future)

Hash-mining: chain in sha-3 candidate-finalis-win function Blake=>BMW=>Groestl=>JH=>Keccak=>Skein. While only cpu-mining (built-in qt miner)

With how few coins that have been generated I highly doubt anyone is gpu mining

Well, all the hash functions are included in the source as .c files, if someone isn't GPU mining without a few hours I don't know when they will be. It should be like Bitcoin in that GPUs will be expected to hash at rates of around 50-100 fold that of CPUs. Most of the algorithms selected are high throughput and benefit strongly from parallelization.

skipping this one, too many coins already which are better (atleast in announcing & releasing)

This is relatively innovative coin with 6 crypto-algoritms (Blake, BMW, Groestl, JH, Keccak, Skein) + block reward depending on difficulty.
CPU-only at this time.
No premine.
That is actually what a lot of people waited for.

Because everyone knows that using six 512-bit hashing algorithms consecutively and then truncating the last 256-bits means that your coins can't be GPU mined, duh! It's not like you can just reduce the search space to what the difficulty is and only check random hashes against the last hashing algorithm, either. Roll Eyes

Someone is GPU mining this right now.

The best thing we can do is get this on an exchange sooner rather then later. Atleast there was no premine and quick diff adjust means no one can dump a large amount of coins.

You can request coins-e at https://bitcointalksearch.org/topic/ann-exchange-launch-of-coins-ecom-exchange-with-over-30-coins-240717 they will probably take you, if not straight away possibly quite quickly if you show you are keen.

LOL how is TRUCoin involved... This will be interesting

Nm not trucoin TRUEcoin

Yep, idea is completely taken out of the "truecoin" by Ukigo.
But Ukigo thought about professional start - premine, the distribution of coins in the forum, the order for coins binding, advertising, writing gpu-miner, etc. But then he changed his mind to create a currency, and the idea hung in the air.

I approached the issue as a hobby, and made only a pure client. Initially, no amenities, but everything is open and honest - the maximum that I could offer.
