Vertcoin - First Scrypt N | First Stealth Address - Privacy without mixer

[jamesl22]

DEV,i found a bug in lyra2.c
please check this code

   //================================ Setup Phase =============================//
    //Absorbing salt, password and basil: this is the only place in which the block length is hard-coded to 512 bits
    ptrWord = &wholeMatrix[0];
    for (i = 0; i < nBlocksInput; i++) {
      absorbBlockBlake2Safe(state, ptrWord); //absorbs each block of pad(pwd || salt || basil)
      ptrWord += BLOCK_LEN_BLAKE2_SAFE_BYTES; //goes to next block of pad(pwd || salt || basil)
      -------------------------------------------------------
BLOCK_LEN_BLAKE2_SAFE_BYTES is 64
the problem is
ptrWord is a 64 bit pointer,but the line ,it add 64,means it add 64*64=4096 bit=512 byte,
so ,the next round ,all ptrWord is zero,
that means Concatenates the basil and padding are not used!!!!!!

you must change BLOCK_LEN_BLAKE2_SAFE_BYTES to BLOCK_LEN_BLAKE2_SAFE_INT64

Surely though, "absorbBlockBlake2Safe" absorbs an entire block of 64 bytes (512 bits). ptrWord is then pushed forward by another 512 bits since +=ing a pointer pushes it forward in multiples of bytes. So on line "ptrWord += BLOCK_LEN_BLAKE2_SAFE_BYTES;", the pointer is pushed forward by 64 bytes (512 bits), and the process is repeated for the next block.

No, pointers work in chunks the same as their variable size.

Code:

uint64_t *ptr;
ptr += 1; // Advances ptr by 8 bytes

uint32_t *ptr2;
ptr2 += 1; // Advances ptr2 by 4 bytes

Indeed... not much we can do now though. Not that it really makes a difference to the end user.

Hi vertans:

I want to share a new paper wallet design, hope you like it.

Very nice design!

Thanks!

Haha, Lekker man

So, you've been in these parts for quite some time? Why don't you communicate on carb regarding crypto:P

Are you still in the mining game?

Have replied via PM. 

a new version based on the latest sgminer5 version is coming, these problems should be fixed (can't test it though, I have only one amd card)

djm34, could you please work with Slix (ystarnaud) to include Lyra2RE into https://github.com/sgminer-dev/sgminer once is stable?

ok, will do

This is great to hear, good stuff guys! 

Hello

Somebody asked yesterday if Vertigo - Vertcoin Lightweight Wallet will be updated for the Vertcoin fork.

Vertigo is going to be updated to the recent Vertcoin fork.

However some technical information details for implementation is needed to know, what needs to be updated, implemented to make the update.

Could somebody from Vertcoin developers provide details about the fork what needs to be updated and or possibly provide updated VertcoinJ library, please?

PS: VertcoinJ library is also used in Android Wallet.

Regards

More great news, hope to see this happen. Keep it up

Okay, 280X is stably above 1.1MH/s with no HW errors at 815/1500. I'm done for a while, I've been messing with this for too long.

Hi wolf, great hashrate for 280x, can you please post your full .bat file?
Thanks!

I'm getting 1100 KHS on a GTX 970 with the miner vertcoin team released

[BitmoreCoin]

what are the features of this alg to combat muitipoll?

It cannot combat multipool.

I have some trouble with the p2pool code, i'm running the windows release on win 8.1 and the pool runs fine, but when i connect to the webinterface these errors pop up.

Anybody else got this ?

I think this happens because there are no shares in the sharechain yet. Once people start mining on the Lyra2RE P2Pool forks this error should go away.

OMG I hate ASICS!! 

I also hate ASICS, they are worthless electrical waste! Don't ever buy an ASIC in your life, most time it is a SCAM and you will never make ROI!

anyone buying a gpu at the moment would probably says the same thing... this is very subjective statement, it depends when you buy and when you get them (can't believe that anybody is buying stuff from people who will use them first to make their own profit... would you buy a "new" car with a 100000km mileage ? probably not, so don't buy anything else either which has been used already... you know who they are and what they are doing, so avoid them...)

[volyova]

GET off the network you GREEDY bastards..

[Equate]

OMG I hate ASICS!! 

Love it or hate it , but if you can ROI on ASICS , then they are great deal and all of it depends on if you get them at the right time. But sadly Pre-orders , Late deliveries , false promises by the manufacturers  brought bad name to the Asics.

if they have a cloudmining service, you know that they will take their time before delivering to you 
The problem isn't much the manufacturers than the "middle men" actually...

What is the minimum compute version on Nvidia for LYRA2?

does GTS450 supported?  thanks
