1  Other / Serious discussion / Re: KYC Safe or Threat on: April 09, 2018, 04:14:35 AM
KYC related to ICO's is a pure threat. Noone from these KYC providers, and I spoke with few of them in person on BtcMiami, can tell why they are collecting this and that. Because there is no written requirements for this usecase. These KYC-ICO providers just simply employ scare tactics against wanna-get-rich-fast "entrepreneurs" and just bank their money. Price is $4-10/person. To add to this - you can get in prison in many countries for storing people private information on your server without accreditation and certification.

- Linux or FreeBSD no questions
- LUKS / GELI encrypted partition
- For Internet connection still better use tethering or CradlePoint
- Dont use RPi as your "center", I used hundreds of them for different projects and reliability and performance is a disaster. Only for narrow-tasked embedded applications. Build cheap, but real PC with Linux. Hell, even Atom-based tiny box will offer 100x time more flexibility then Pi with just a little higher power requirements. If you still set at Pi, consider TinkerBoard or BeagleBone as alternative.

Great post! When talking to people who are not submerged to a crypto information pool for a long time you quickly learn that their inability to get quality information already built a wall in their brains and they "filtering" every source now. That is not helping adoption for sure, its hard to break that wall.

Due to its nature Bitcoin gave birth to many wealthy monsters who are very well organized and financially educated to profit from it. I would love Bitcoin foundation to be more like FreeBSD foundation. It produced one of the best OS on a planet and functioning for 17+ years like a clock. You have to have strong authority to produce single source code tree in contrast with Linux/etc. Maybe something to learn from this example?

Said that I think this forum is on right track with all efforts and latest changes, I am actually surprised it is still that coherent considering speculative intent of overwhelming amount of participants. Keep up the great work!

You dont need SSD to store blockchain, it just better be internal drive, not a usb connected. I have all of them sitting on Sata (AHCI) 4tb one. It syncs in minutes on daily basis. Cpu/memory is also a key. Geth is much more resource/disk hungry if you need ETH there as well.

I would highly recommend to build low cost desktop to store all crypto flavors. Junkyard i5 Dell would do it. 2 drives - OS on SSD (small, like 80-120gig, better 2 of them in raid 1 for piece in mind) and big one for chain. 16 gig ram min.

you can specify -datadir=xxxx command line option to bitcoin-qt to separate these data directories

also I would suggest pulling bitcoin wallet build from github: https://github.com/bitcoin/bitcoin/releases

When installing linux on SSD, encrypt all drives with LUKS/etc

Good luck!

I see biometrics can be used as a source of entropy/seed while generating keys. However, it should never be deterministic. It just too "fuzzy" for that.

Most of biometrics does not produce fixed data blob every time you run it, instead recognition system "trained' and produces probabilistic classifier (Sift, HAAR, AAM/ASM in computer vision/face recognition). Classifier being applied to your blob generated by biometrics tells you probability - like 0.87. You set the threshold what should be considered "true" and what "false".

No way to figure out... Wording and writing style of email is different comparing to WP, but that's rather what should be expected.

Core wallet data takes now exactly 178,920,580 bytes, it doesn't grow too quickly, but pretty much already in desktop/workstation category.

What country and industry you were in? Age? If you dont have kids, then it's not a disaster. Cut ALL expenses, eat ramen for a while, write good resume based on good examples and start looking internationally. Dont "invest" in anything risky. If it goes from bad to worse, you can always pick up low wage jobs like washing dishes that will hold you afloat while you looking.

Code:
dyld: Library not loaded: @rpath/libcudart.9.1.dylib

Thanks for the effort.  Smiley

Any idea where I can get libcudart.9.1? Is it from an SDK for CUDA?  Thanks!

Yes, you need this:

https://developer.nvidia.com/cuda-downloads

It's a full dmg package that I used for cuda 9.1.

To my surprise, still mining non-stop with same hashrate Smiley

That would be a bad idea and will possibly trigger audit depending on the amount. Within your range, nobody will probably notice that, but it's still bad idea.

Also if you haven't got 1099-K form (and IRS haven't got it) from Coinbase, reporting it to IRS can be a trigger of audit as well. No joke, they may even refund you this money back in a year/two with interest - under certain limits it's all done automatically with no humans involved on their side.

no one gives a shit about mac's lol

Haha obviously thats true, cant blame them. Anyways might be useful for some lonely souls Smiley Still mining 26.33 stable.
11  Alternate cryptocurrencies / Mining (Altcoins) / OSX Mac/Hackintosh ethereum miner CUDA build on: February 06, 2018, 11:02:55 PM
Just went through the process of building ethminer with Cuda for OSX - it appear simple but devil in the details, its very frustrating... I spent way too much time on it, but finally it works! No more idle time for Nvidia on mac!

Hope it will save somebody a lot of time and frustration who is up for same challenge. It's a Genoil/chfast one:

https://github.com/ethereum-mining/ethminer

For some evil reason lol they provide Mac build but it crashes in OpenCL and not compiled for Cuda at all. You need build 0.12. It works for opencl only, but speed is a disaster - ~2mh on 1070. Newer builds not working on OSX at all.

So what I did - 10.13 High sierra, latest Nvidia web drivers, latest Cuda 387.128, lots of pain and suffering and build is here:

https://drive.google.com/file/d/1llztDndIvW119It897sRDFurTjD5kEo-/view?usp=sharing

To run in Cuda Mode for example on ethermine pool:

./ethminer --farm-recheck 200 -U -S us1.ethermine.org:4444 -FS eu1.ethermine.org:444 -O 0xYOURETHADDRESS

you can try OpenCL as well (-G instead of -U, but its horribly slow)

1070 getting 26.33 Mh/s, not that bad.

One more thing - for some reason 3gb cards work on Linux version, but on Mac - nope, dont even try, you'll get memory allocation error.



12  Other / Ivory Tower / Re: When is it safe to give our KYC/AML info? on: February 06, 2018, 03:55:30 PM
I talked to a lot of KYC/AML "providers" on BtcMiami conference. They are all pitching their cool solutions (some of them really cool - such as apps with face recognition, connected to driver licenses db in US, etc). $3-$10 per person.

Hardest questions noone of them could answer:

- what guarantee you have that your solution is compliant? There are none, because noone has these guidelines/policies to match. There are AML regulations for financial institutions, but they are totally different

- they store your data on their servers, no certification of security compliance and probably illegal in most countries due to collision with their privacy terms

- where and how they obtained blacklists / databases of private personal data? I bet there is no way DB for face recognition of US citizens can be given to a "blockchain" company

Hopefully it helps.

And to answer (2) - if your project passes Howey and has all ingredients of utility, such as immediate use in platform - you actually dont need KYC/Aml. But it's still a gray area, because it's not a black and white test, and all depends on wording and experience of your legal team.

Will watch closely this one - I bet noone even come close to founder with 40yrs experience building MLM's internationally. I wonder what is the readiness state of the platform and would like to see working demo.
14  Other / Serious discussion / Re: IPFS is a Game-Changer? on: January 30, 2018, 06:12:22 PM
IPFS needs a lot more development. Honestly it's better on paper then in practice now, but has enormous potential and is very promising.

Biggest issues so far - "Pinning" and redundancy, private group and network support and simple versioning of resources is a disaster. API's are also lacking and not catching up in time with main daemon. So if you inclined to try it in your app, you are looking at forking code/api for sure
15  Alternate cryptocurrencies / Altcoin Discussion / DAICO - what are your thoughts about it? on: January 30, 2018, 05:56:33 PM
I cant find relevant discussion by searching, so sorry if it's duplicate...

Vitalik recently posted his thoughts on "improving" ICO model by combining it with some DAO features:

https://ethresear.ch/t/explanation-of-daicos/465

I have really mixed feelings about this one. It may work well if amount of participants in said DAICO is very large, otherwise future of the project can be and will be heavily manipulated. It's common practice in conventional investment models when people "buying in" into board seats, bribe/make alliance with other board members and do whatever they want with company otherwise.

Would love to hear your thoughts about it. Thank you.

If you have time to spare, verifiable experience and references, please PM me.

Experience with mitigation of DDoS attacks and other cyber threats is a big plus. Diversity of experiences with various environments and systems would be the best.

Please also drop me a line if you would be interested in becoming a beta tester of cyber threat protection system.

Thank you!
17  Alternate cryptocurrencies / Mining (Altcoins) / Re: Huge difference on hashrate on: January 28, 2018, 02:58:00 PM
now it seems to be stable at 120 ~ Mh/s on the website. still 16 Mh/s les than on the miner. but after it is stable.

my shares are these following during last hour.  105 (97%) / 3 (3%) / 0 (0%)

Idk if these are fine. but it seems better already. lets see if during the day it stays at this ratio

Dwarfpool is better than ethermine.org ?


thank you

This looks normal, nothing is wrong with ethermine. Reporting of hashrate seems to be based on a number of shares submitted averaged in time, so it will fluctuate. You may see up to 150 from time to time. Good luck!
18  Alternate cryptocurrencies / Mining (Altcoins) / Re: Huge difference on hashrate on: January 28, 2018, 01:30:32 PM
How high are your stale/invalid numbers? What ethminer build you using, 0.13.0? Difference seems to be excessive, especially if it stays like that for days.
