I have officially reached ROI with my DMD cloudmining and now I am in a nice earning mode. Willing to share my info with anyone interested. I ve been reading a lot of threads about how it is not possible to reach ROI and make profits with cloud mining. Well, when it comes to DMD Diamond, IMPOSSIBLE IS NOTHING.

thx for ur feedback crazyivan!

below for example stats of another user "stoody" who joined with start of cloudmining
he is at 138% ROI now (thx mate for allow show ur stats)

and here the stats of whole DMD CLoudmining 122% ROI
(yes we paid out more value than people invested so very clear sign this is legit stuff)

we were at the begin of our coin scrypt. to be able sync from zero a wallet need to be able read/verify that old scrypt hashed blocks too

OK so still needed but obsolete ... only needed for syncing a wallet from 0 ... or importing a private key
so still need assembly code .S files Sad

and who knows when a scrypt-aarch64.S will be written Sad

Quote

which would basically be a start at block 0 but each User keep his balance

so a total balance would be taken for each address detected in the blockchain up to the point of switchover from scrypt to groestl?
This would be acceptable to me

basically a genesis block with these totals? and get rid of scrypt code entirely?

Just distribute new genesis block with new wallet source code.
Make it a MANDATORY update

If I ever get 2.0.5.7 wallet to run on aarch64 I can generate a diamond_wallet.deb:ARM64 archive executable ...

@devs
Probably a dumb question but why is scrypt_core() even used, I thought we are groestl now not scrypt

is this just dead code??? not needed anymore?

we where at the begin of our coin scrypt
to be able sync from zero a wallet need to be able read/verify that old scrypt hashed blocks too

we have a internal discussion in DMD Diamond Foundation core slack channel about slim and slow down DMD Blockchain

which would basical be a start at block 0 but each User keep his balance
together with a optional slowdown (we are now one of fastest coins with 52 sec average blocktime but do we need that speed?)
we could create a ultra slim wallet and chain size that would fit easy on every device and sync very fast

additional nice sideeffect we could remove all historic relevant code parts from wallet and leave only really actual needed one in it
this would slim and streamline wallet code too

From pooler:

Quote

As I've told you in my email, I still haven't been able to test cpuminer on aarch64, but time allowing I plan to look into this soon.
If you're OK with an unoptimized build, I think as a temporary solution configuring with --disable-assembly should be enough.

Looking thru pooler cpuminer source http://sourceforge.net/projects/cpuminer/files/pooler-cpuminer-2.4.4.tar.gz
Noticed PPC is supported also (scrypt-ppc.S) https://en.wikipedia.org/wiki/PowerPC https://www.debian.org/ports/powerpc/

This could be easily added to DMD source

Untested as yet, I don't have a PPC to try it on.

Another subject: Compiling cpuminer (minerd) for aarch64 without architecture optimizations worked:
./configure --disable-assembly
make

executable was created

apparently there is C source in his archive somewhere for scrypt_core() Huh

back to DMD:
how to --disable-assembly with qmake since no ./configure is provided with DMD src?

Anyway. There is a lot of speculation but little hard info. But Windows 10 Mobile is indeed being ported to ARM64 (no surprise there) and x86. And I’m curious to see how that works out in real products.

source: https://www.thurrott.com/windows/windows-10/63961/63961

If I understand the whole concept of ROKOS, it can run headless and we are looking for a cheap staking device ...
The future is aarch64 and we need to support it

ODROID-XU4 Octacore aprox 90$
or ODROID-C2 Quadcore 40$
(both come with 2gb)

...offering the best performancebang for the buck atm imo.

lets see
if i get below 100$ a windows based 2 GB ram solution that can use precompiled wallets with a well known gui (windows)

i think thats a more mainstream solution

dont forget all that prices u state is a mainboard with nothing no case no power no touchscreen

a windows 10 tablet have that all

and worst case if u no longer care for crypto ur kids are happy have another tablet to watch youtube and other stuff

diamond wallet won't compile on aarch64 yet, need a new scrypt-aarch64.S written which is not in source, scrypt-arm.S fails to build on 64 bit Sad

everything else in source I have gotten to compile but it fails at link time, this is because scrypt_core() never gets built.
As feldenthorne suggested a fallback code written in C++ could be a temporary solution for scrypt_core() for any architecture that is not supported yet, although it would surely be slower than assembly code for inner loops.
It's up to the devs ... simply list it before the scrypt-*.S files in diamond.pro, it would get compiled first and then if an architecture that matches get's compiled it would replace the C++ version before linking.
There are three other files that need to be fixed for aarch64, which I have already done locally (diamond.pro, src/makefile.unix and src/scrypt_mine.cpp)

It looks like you guys in the thread have already figured it out: someone will need to write a scrypt-aarch64.S file for everything to work smoothly.

Alternatively, I could probably have the wallet fall back to a C++ implementation on unsupported architectures. It would just need to be transparent to the users that their architecture does not perform as well as it might with its own assembly implementation. (That is to say that the performance would be really bad compared to a native solution.)

Speaking of performance hits, though, I'm pretty sure one could the ARM version of QEMU to run a 32-bit binary if you just want to run the wallet on an arm64 board. At least until a more robust solution is found. A guide for setting QEMU up on a Raspberry Pi can be found here, but I'm not sure how well that translates to ODROID's boards. You might have to set up ODROID's boards for virtualization (if they support it) and compile QEMU yourself to get things working.

need scrypt-aarch64.S for it to really be a solution ...

scrypt-arm.S is taken from pooler cpuminer ([email protected]) and he said:

Quote

As documented, there is no Aarch64 implementation in cpuminer.
I do plan to add one in the future, time allowing.

I'm also working with OKtoshi on ROKOS for aarch64 however he does not have a board yet ...
https://bitcointalksearch.org/topic/m.14308714

I'll bet DMD foundation would post a bounty for someone to create src/srcypt-aarch64.S
here is src/srcypt-arm.S as a starting point: https://github.com/DMDcoin/Diamond/blob/master/src/scrypt-arm.S

With the release of RPi 3 out and PINE64+ imminent, there is going to be a large demand for aarch64 support.
I'm lucky to have got the Odroid C2 board, they are sold-out till mid-April. Specs are quite similar on all Only the Odroid C2 has 2 GHZ though

I PM'ed pallas too but have not got a reply, he's into stuff like this I think ...

Should PM wolf0 too

By the way, who is DMD wallet dev nowadays ... used to be danbi but we don't hear from him much at all ...

another review:
http://www.jeffgeerling.com/blog/2016/review-odroid-c2-compared-raspberry-pi-3-and-orange-pi-plus

@feldenthorn
If you can give me example C++ code for maybe I can create aarch64 assembly code from it (I have been looking at several arm 32 bit to aarch64 sites), may not be optimized to the max but just need to get wallet to build for now. Hell of a way to learn LOL.
I can probably do a side-by-side C++ to assembly code and later tune it with loop un-rolling etc.

u could put C++ fallback code for scrypt_core() in scrypt_mine.cpp, this is where it is used and defined as extern "C".
