Recently I have re-deployed my RTX-3070's from hacking btc do mining ETH, which is very profiitable now
These old GTX1060-3gb cards are worthless, but just experimenting around I made an interesting discovery.
Normally the 1060-3 would do about 50MH/sec, but when I put the hacking tool on its own NVME m.2. on the MOBO I found that the 8gb bloom filter was almost 100% allowing the GPU to run at max
Now I have 300M addresses from BTC that have value, placed in my 8gb bloom filter gives a false positive of one in a trillion-trillion-trillion, so not often
The 250 MH/sec is how often a private key is created ( more on this later ), and then all possible (comp/uncomp) addresses (h160) are ran through the bloom-filter, so the through-put is really 250 M & 300M , or almost 1,000 TH/SEC address compares, but really higher because I'm doing 4 different combinations so its 4,000 TH/sec, on just one card, but I'm doing six on a rig, so its 24 PH/sec
This yields about one lost address per week to be found
For the record the rtx-3070 was doing 1,000MH/sec, but I was just running the bloom-filter off of an SSD, but it was shared, I have never tested a standalone NVME with the RTX, I could imagine they would do 1TH/sec easily.
WHat's all this mean? Well in BTC secp256k1 you got 10e77 combos, 1/2 that to birthday you got 10e36, divide that by 10e15, and you get 10e15, that many seconds tells you how often you should have a hit in real time, old calculations were on the order of one every 1,000 days.
But on a rig I'm see way more often, because I guess for the simple matter is the napkin, is always different than real world.
So what are the tools?
1.) hack up vanity-search, which is the best gpu solution for generating keys 2.) add the 8gb bloom filter, note that linux only support 4gb shared memory, so the bloom must be cascaded, note that brain-flayer only used a 512mb bloom, so creating a 8gb bloom is a major task in software engineering 3.) hack up vanity-search so that on every new key, its runs through the bloom-filter for every possible address that can be generated, comp, un-comp, h160, eth,...
The Gtx-1060 only uses 970mb of memory, so in effect even the older gtx750 could be used here Smiley
I spent a few years ago spending time putting the bloom-filter on the gtx-1070, but even though there is only 8gb, you can only allocate 700mb max at a time in CUDA dev, so I found near impossible to get a working 4gb bloom running on a GPU, so I fell back to doing it on the CPU.
Note in my rig here I'm just using an 2core i3 ( $50 cpu ), with 4gb memory, as this is essentially 100% gpu
I'm just sharing this cuz well its my hobby, and I have to report.
Lastly, just for the record, like the original brain-flayer dude, I don't spend the coin, I don't even own a single exchange on earth, what I do when I find btc, is I put it in a database, and watch how long it takes be spent after I find it, I have found to date, that almost all coins are gone < 1 yr, which tells me I'm not the only one playing this game.
The selection of random-keys in vanity-search is very critical, of course all that code has to be stripped, as your not looking for prefix, I use a baby-step/giant-step algo that runs through public-keys, where I have 100's of 1,000's every 20 minutes randomly search for a new key from that public hash ( of known high-value ), I do this to make sure that my private key search space is within known valuable addresses, as I'm not looking for a prefix like vanity, I'm looking for a random public address of known value. The 20 min idea, is that time try another, because of scale of the pool, there isn't much duplication.
Me too, in my youth some of the strangest super intelligent people I ever came across were Ayn-Rand Lovers, I'm talking PHD rocket-scientist type people. I think they're attracted to the ideal that people like them should be at the top of the pyramid. While in reality 'winning' in the USA is only about being the in the right place at the right time.
...
WRT Russia opinion, I know lots of Russian's I live in Asia. They're always the most intelligent people I ever meet, but the common is they have all left Russia, to make it else-where, especially USA, where its just so easy for them to get rich.
Ayn Rand essentially having read her in my youth, and watched all the new movies like 'Atlas Shrugged' depicting her paradise. I think is just pure Ideology, of course is not real, as we know Libertarians will always defend pollution, because it the right of everyone to get rich.
Ayn Rand was for an era, an Era where USA had won the war, where everybody in USA could get rich, where the commies were trying to sway public opinion, but they lost, until things just turned ugly post Y2K, and 2007 financial collapse. Now with COVID after-math & the reset the USA is a terrible mess. It ain't coming back. Living here in ASIA I can tell you everything is just fine, mostly because of the homogeneity people aren't at each other's throats with 'woke-ness'
Essentially for 40+ years USA with 5% of the worlds population, consumed +80% of the resources, today most USA citys are cesspools, and yet in ASIA most city's look like Disneylands 1960's "Tomorrowland", clean & beautiful. The problem of course is that post 1970's the Elite of the USA quit investing in the USA, so now 50 years later all the bridges are collapsing. Money always flows to where its most influential.
I really don't think Ayn Rand saw anything of this coming. Today China is 100X more "capitalism" than USA, where the USA is just a third world country with nukes. Most the world talking "Ayn Rand" wouldn't even get you a cup of coffee. All the people who used to love Rand, are long dead. Orwell & Huxley have far more influence, because their ideas is our present reality.
Let's see, in order to have a wife, you need to be rich, have a house, a car, and be an exec at a major company. The one-child policy has put these kinds of demands on boyz in china for years. Its even called the 'little king',
But the most glaring problem is that there aren't many 'exec jobs' in china, Just like usa, most USA urbans don't become major league basketball stars, rock stars, or Fortune 100 CEO's; in china, most college grads don't become ceo-execs, there just isn't enough slots for the billion people.
All this causes a lot of demand to get 'rich quick', sure most got a girlfriend in college, but in order to 'marry her', you got to meet approval of the mother. Huge pressure in china for the little kings to carry on the legacy of the family name, they must get the wife and make offspring, or they lose face.
The above said, todays billionaire of course is like yesterdays millionaire, growing up myself a millionaire was a big deal, IMHO today everybody that owns a house is a millionaire, so what?
So today in China, if you want to have a wife you must set sights high.
Then there is the jack-ma problem, so you become a billionaire, and you own the monopoly per sam here or peter theil, then of course you become a target of the CCP and you eventually 'dissapear'
Having lived in China, on&off the past 40+ years, I can say I have seen amazing change, from normal poverty to the worlds first class 'disneyland/tomorrowland' for most citys.
The other thing today, is everybody in ASIA is playing 'crypto' I think that post y2k era, with the exception of the unicorn thingy on this site, its not easy to become a ceo of your own company like it was post 1980's
So the problem is still there, if you want a wife you got to be rich, but the only way people can get rich is crypto, so everybody is in over their head.
Well to summarize this topic, friends probably don't want to lose friends, once the boy is a billionaire, he's got a wife&kids, you never see him again, the others who are still 'poor' can do the misery loves company thingy.
This is all because of the one child policy. Now if you look at the USA, this is not a problem, most people can hookup if they wish. Wealth helps, but its not critical.
Just to make something clear having lived in China, that in the rural area's its common to see 2-3 sons, people need the labor, its only in the City's that the one-child policy was ruthlessly enforced.
Dehumanizing all life-forms, just another justification of genocide.
MIL blows stuff up and kills people, they have no other purpose to exist. Especially in SV, where 90% of all work is essentially DOD of course CIA-NSA owns all the big, like google, oracle, facebook, amazon.
ET is here, they can look just like us, and their execution should cause no alarm, thus the narrative is born, see the more on TV.
...
Some say the MIL dis-information about ET (UFO) is to reduce populate and cause world panic, true but its best to call 'population reduction' what it is, and that is genocide.
On the subject Feynman, said it best long ago when asked this question, "In our entire human history, we have no proof of aliens, what hasn't happened yesterday, isn't likely to happen tomorrow".
I think they're very useful, if your a guy like Musk, who needs to move billions of USD, anonymously. You can't carry gold around, nor diamonds anymore with full body scanners. BTC is the only way to move massive wealth, ergo why NK is using it to buy WMD material's & know-how.
USD is backed by guns ( nukes ), what is BTC back's by? Large numbers, 10E77 (2E256), greater than the number of sub-atomic particles in the universe. You more likely to find a nickle lost in our galaxy, than to find a specific BTC private-key.
The problem with the question here, is nobody thinks like a rich guy, let's fall back to JP-Morgans famous "Only gold is money, all else is credit". I hate to admit it but BTC in most recent decade has largely vacuumed up all the paranoid money that would normally be in gold.
I don't even want to touch on the fact that SHA256 & ECDSA SECP256k1 are both NSA algos that are backbone of BTC. In my day the NSA didn't release an algo that they didnt' have a backdoor key.
IMHO BTC is a great way to move massive wealth, but only the rich can play this game. From a GUV point of view BTC has kept the paranoid money out of gold, let's remember the original Satoshi white-paper came out of IMF-NSA, in 1997.
I myself have played BTC since 2011, and have hacked it since then, as its always been more fun to hack Secp256k1 ( big prime numbers and such ) than thinking about 'money' of which I have no use.
The problem that I see is like Alfred H Proofrock in the famous TS-ELIOT 'women come&go speaking of Michelangelo', IMHO BTC requires a total classic knowledge of math, physics, computation, and economic history to 'get-it', and thus given that most are not masters of these four, they're not unlike the wisemen holding different parts of the elephant.
In summary BTC is a toy of rich men, and it will go away when the NSA-IMF decides open the backdoors of sha-256&secp256k1. Even then newer coins will come out using sha-512, and secp512k-n, and the game will continue, as the crypto-currency model has been proven, and road-tested.
My advice for little people is to diversify, say have a little of everything, some gold, some farm-land, some stock, some cash, and most important of all to hold a passport is 'good country' when the SHTF in the USA. Today, I think it much better to play ETH and/or ZEN, which have had better gains, and still are profitable to mine, which allows you to accumulate with privacy, as the coinbase (or any 'exchange') purhcase of crypto is just an IRS database. I would say like gold, 5% crypto, and as along as its a good crypto, it doesn't really matter. By good I mean backed by good-teams, which is why I like ETH and/or ZEN;
BTC is a barometer that's why my #1 hobby is cracking BTC ( factoring ECDSA primes using GPU farms ) its field-medal level math, that you will never get public recognition for solving.
