https://github.com/gridcoin-community/Gridcoin-Research/releases/tag/18.104.22.168 Finally! After over ten months of development and testing, "Fern" has arrived! This is a whopper. 240 pull requests merged. Essentially a complete rewrite that was started with the scraper (the "neural net" rewrite) in "Denise" has now been completed. Practically the ENTIRE Gridcoin specific codebase resting on top of the vanilla Bitcoin/Peercoin/Blackcoin vanilla PoS code has been rewritten. This removes the team requirement at last (see below), although there are many other important improvements besides that. Fern was a monumental undertaking. We had to encode all of the old rules active for the v10 block protocol in new code and ensure that the new code was 100% compatible. This had to be done in such a way as to clear out all of the old spaghetti and ring-fence it with tightly controlled class implementations. We then wrote an entirely new, simplified ruleset for research rewards and reengineered contracts (which includes beacon management, polls, and voting) using properly classed code. The fundamentals of Gridcoin with this release are now on a very sound and maintainable footing, and the developers believe the codebase as updated here will serve as the fundamental basis for Gridcoin's future roadmap. We have been testing this for MONTHS on testnet in various stages. The v10 (legacy) compatibility code has been running on testnet continuously as it was developed to ensure compatibility with existing nodes. During the last few months, we have done two private testnet forks and then the full public testnet testing for v11 code (the new protocol which is what Fern implements). The developers have also been running non-staking "sentinel" nodes on mainnet with this code to verify that the consensus rules are problem-free for the legacy compatibility code on the broader mainnet. We believe this amount of testing is going to result in a smooth rollout. Given the amount of changes in Fern, I am presenting TWO changelogs below. One is high level, which summarizes the most significant changes in the protocol. The second changelog is the detailed one in the usual format, and gives you an inkling of the size of this release.
Note that the protocol changes will not become active until we cross the hard-fork transition height to v11, which has been set at 2053000. Given current average block spacing, this should happen around October 4, about one month from now. Note that to get all of the beacons in the network on the new protocol, we are requiring ALL beacons to be validated. A two week (14 day) grace period is provided by the code, starting at the time of the transition height, for people currently holding a beacon to validate the beacon and prevent it from expiring. That means that EVERY CRUNCHER must advertise and validate their beacon AFTER the v11 transition (around Oct 4th) and BEFORE October 18th (or more precisely, 14 days from the actual date of the v11 transition). If you do not advertise and validate your beacon by this time, your beacon will expire and you will stop earning research rewards until you advertise and validate a new beacon. This process has been made much easier by a brand new beacon "wizard" that helps manage beacon advertisements and renewals. Once a beacon has been validated and is a v11 protocol beacon, the normal 180 day expiration rules apply. Note, however, that the 180 day expiration on research rewards has been removed with the Fern update. This means that while your beacon might expire after 180 days, your earned research rewards will be retained and can be claimed by advertising a beacon with the same CPID and going through the validation process again. In other words, you do not lose any earned research rewards if you do not stake a block within 180 days and keep your beacon up-to-date. The transition height is also when the team requirement will be relaxed for the network.
Besides the beacon wizard, there are a number of improvements to the GUI, including new UI transaction types (and icons) for staking the superblock, sidestake sends, beacon advertisement, voting, poll creation, and transactions with a message. The main screen has been revamped with a better summary section, and better status icons. Several changes under the hood have improved GUI performance. And finally, the diagnostics have been revamped.
The wallet sync speed has been DRASTICALLY improved. A decent machine with a good network connection should be able to sync the entire mainnet blockchain in less than 4 hours. A fast machine with a really fast network connection and a good SSD can do it in about 2.5 hours. One of our goals was to reduce or eliminate the reliance on snapshots for mainnet, and I think we have accomplished that goal with the new sync speed. We have also streamlined the in-memory structures for the blockchain which shaves some memory use. There are so many goodies here it is hard to summarize them all. I would like to thank all of the contributors to this release, but especially thank @cyrossignol, whose incredible contributions formed the backbone of this release. I would also like to pay special thanks to @barton2526, @caraka, and @Quezacoatl1, who tirelessly helped during the testing and polishing phase on testnet with testing and repeated builds for all architectures. The developers are proud to present this release to the community and we believe this represents the starting point for a true renaissance for Gridcoin!
Most significantly, nodes calculate research rewards directly from the magnitudes in EACH superblock between stakes instead of using a two- or three- point average based on a CPID's current magnitude and the magnitude for the CPID when it last staked. For those long-timers in the community, this has been referred to as "Superblock Windows," and was first done in proof-of-concept form by @denravonska.
Network magnitude unit pinned to a static value of 0.25
Max research reward allowed per block raised to 16384 GRC (from 12750 GRC)
New CPIDs begin accruing research rewards from the first superblock that contains the CPID instead of from the time of the beacon advertisement
500 GRC research reward limit for a CPID's first stake
6-month expiration for unclaimed rewards
10-block spacing requirement between research reward claims
Rolling 5-day payment-per-day limit
Legacy tolerances for floating-point error and time drift
The need to include a valid copy of a CPID's magnitude in a claim
10-block emission adjustment interval for the magnitude unit
One-time beacon activation requires that participants temporarily change their usernames to a verification code at one whitelisted BOINC project
Verification codes of pending beacons expire after 3 days
Self-service beacon removal
Burn fee for beacon advertisement increased from 0.00001 GRC to 0.5 GRC
Rain addresses derived from beacon keys instead of a default wallet address
Beacon expiration determined as of the current block instead of the previous block
The ability for developers to remove beacons
The ability to sign research reward claims with non-current but unexpired beacons
As a reminder:
Beacons expire after 6 months pass (180 days)
Beacons can be renewed after 5 months pass (150 days)
Renewed beacons must be signed with the same key as the original beacon
Magnitudes less than 1 include two fractional places
Magnitudes greater than or equal to 1 but less than 10 include one fractional place
A valid superblock must match a scraper convergence
Superblock popularity election mechanics
Yes/no/abstain and single-choice response types (no user-facing support yet)
To create a poll, a maximum of 250 UTXOs for a single address must add up to 100000 GRC. These are selected from the largest downwards.
Burn fee for creating polls scaled by the number of UTXOs claimed
50 GRC for a poll contract
0.001 GRC per claimed UTXO
Burn fee for casting votes scaled by the number of UTXOs claimed
0.01 GRC for a vote contract
0.01 GRC to claim magnitude
0.01 GRC per claimed address
0.001 GRC per claimed UTXO
Maximum length of a poll title: 80 characters
Maximum length of a poll question: 100 characters
Maximum length of a poll discussion website URL: 100 characters
Maximum number of poll choices: 20
Maximum length of a poll choice label: 100 characters
Magnitude, CPID count, and participant count poll weight types

Below are notable difficulty adjustments when hash rate fell and block times become slower for Bitcoin.
26 Mar 2020 [difficulty adjustment -15.95%, avg block time 11min 54secs]. On the 28th price crashed from $6674 to $6138 ( -8%).
8 Nov 2019 [difficulty adjustment -7.1%, avg block time 10min 46secs]. On the same day price crashed from $9234 to $8783 ( -4.88%).
The next big adjustment was around Nov to Dec 2018 and there were 3 big adjustments with high block times.
19 Dec 2018 [-9.56%, avg block time 11min 3secs]
3 Dec 2018 [-15.13%, avg block time 11min 47secs]
17 Nov 2018 [-7.39%, avg block time 10min 48secs]
There was huge drop off starting on 14th Nov all the way to a bottom on 14-15th Dec ($6351 to $3288 around -48%).
Current situation: We are 1 day 10 hours from the next difficulty adjustment. Projected difficulty adjustment is -5.61% (https://fork.lol/pow/retarget), which could indicate a small dip. However, take note that the date of last adjustment was the 5th and the 3rd halving was on the 11th, between the 5th to the 11th there was increased hashrate from miners trying to mine the final week of 12.5btc that offset the really slow block times after the halving. Therefore it will be the next difficulty adjustment after the one on the 20th that will completely reflect the slower block times after the halving. Currently the median block time taken on the 17th was around 14min (-28.5% difficulty adjustment). For people who do not understand blockchain, basically with the Bitcoin 3rd halving, mining profitability fell for a lot of miners and they probably turned off their miners therefore the blockchain mining time became considerably slower which is reflected with slow transaction speed and higher fees as seen currently. Bitcoin sellers moving their BTC from wallet to an exchange are faced with slow transaction speed and therefore the sell pressure of BTC fell considerably which will attribute to the current price increase. There is a correlation between sell pressure and blockchain congestion (the size of the correlation is undetermined). There is going to be a race. A race between BTC price hiking high enough to attract more miners to reduce avg block times versus the closing window of roughly 2 weeks before the next difficulty adjustment. If the price does not jump high enough, the next difficulty adjustment in the first week of June could signal a huge dip. I am not an expert. I just did some research on the above and wanted to share with fellow Bitcoin compatriots so that we can tread with caution and not lose our shirts. I do not plan to short BTC but I will exit my BTC positions if I expect double digit negative difficulty adjustment in early June. Please visit the original post here https://www.reddit.com/Bitcoin/comments/gm23pe/warning_blockchain_difficulty_adjustment/ There are pictures in the original post as well as 2nd halving evidence with pics. I could not post pics here. If possible please upvote the original post, a lot of people downvote it. Not sure why people downvote it, maybe veterans attempting to hide information from newcomers to fleece them of their shirt. Update 1:>! As of writing, I have opened a small short position on Bitcoin. Stop loss around 10k, estimated take profit around 8500. The reason is because the difficulty adjustment in the next 20 hours, even though is just -5% roughly is still significant. I direct you to look into all the difficulty adjustments in the last 2 years and you will know how rare it is. The ones I caught were all listed at the very top of the post. Since it is my first time shorting BTC, I take this as a learning opportunity so that I will have some experience to face the bigger difficulty adjustment in the first week of June. Analysis into execution, even in failure I am happy.!< Update 2: The difficulty adjustment (DA) happened roughly 6 hours ago and the sell pressure from -6% DA did not seem to be affecting the market much. However, please take a look now at the estimation for the next DA. On https://bitcoin.clarkmoody.com/dashboard/ it is estimated to be -25%. On https://fork.lol/pow/retarget estimated to be -18%. On https://www.blockchain.com/charts/median-confirmation-time the median block time for the last day was 16.8min. My original proposition that the true DA of the halving can only be realized in the next DA stands and that it will be considerable. The increased sell pressure from that DA will be highly significant. That is why there is a race by current miners to get the BTC price up high enough to attract more miners to not have the DA drop too much. Update 3: Current BTC price at $9100 ( ~39 hours after DA). Then again BTC could have dropped from all sorts of reason. However the coincidence with the DA and with all the past DA is just too high to simply shrug off as irrelevant. Anyways past result cannot predict future ones, stay safe with the trading. Will no longer check on this post.

big miners make BTC blockchain stalled intentionally?
I've been monitoring BTC chain last 2 weeks and found something interesting. When blocks are solved, they would be solved pretty fast, mostly under 7 minutes. But when the chain stops moving, time to solve a block is around 20 minutes to 45 minutes. I know everything can happen in terms of probability, but this happened quite often, so I don't believe it's not an intentional action. There're 2 main reasons that most miners may decide to "rest" at a specific time: - Make all transactions stuck, so people have to increase their fees (if they are in hurry). Last 2 weeks, there were at least 2-3 times mempool reached 25k transactions (excluded the time when BTC surpass $10k) and the fees were insane. - Make the diff remain "low" enough. So they can maintain a good revenue/electricity_cost ratio. Assumes when they stop mining BTC, they switch to other coins. By one action, they'll have better rewards on the next few blocks and don't change the diff of next epoch. It's kinda a type of game theory that when you stop mining BTC at a specific time you have to be sure other miners stop mining BTC too. My gut feeling is telling me that it's true. Because speaking of a long-term plan for mining bitcoin, this strategy is the best.

At block 630000 we were 51 blocks ahead in the difficulty epoch and now we are 54 blocks ahead. Seems like the hashrate hasn't dropped at all and it's continuing the rate which will lead to a difficulty increase. Doesn't anyone find this surprising? I was expecting at least a 10% drop in hashrate due to the old miners being turned off. This means that practically all miners were having a 50% profit margin before the halving. Has electricity used for mining become cheaper than the already low 5 cents/kW? Could have most miners shorted bitcoin at $10k to hedge themselves from price and halving?
This is general advice and my opinions They are based on many years of experience. ... and to be CLEAR, I am in no way affiliated with any of the sites running today or mentioned here. I don't make ANY money from them... I could care less if you take the advice or shit all over it. This is not an advertisement for any one site... It is my opinions based on my experiences in this industry. I have made a LOT of money in the industry, and made a lot of other people a lot of money. There are good and bad things about every site out there, some I recommend here, others I will shit on, but I make nothing, own nothing, am not affiliated with any of them. I have often been asked a LOT of questions by people looking for advertising and website help. I decided this was the best way to answer all the questions and help the community. I hope you can learn something from this that helps you as you advertise or even better keeps you safe.. I worked for backpage for a long time, I helped start the bitcoin payment side of the site, I also helped start one of the backpage replacements. I have consulted on 2 other clone site startups, and to top it all off.. I owned a escort agency on the east coast from 2003 to 2011. I owned my agency with 2 partners, I kinda fell into it. They needed computer help, I was a computer and marketing guy. SO through all of that I am pretty sure I know a LOT about advertising for sex workers and the industry in general. For Escorts and sexworkers things are very different in today’s post backpage.com and SESTA/FOSTA world. These changes and new laws are having serious effects on advertising adult services. Here are a list of things to consider: Many of us remember Escorts.com, and Craigslist. Those were really the only places a SWr needed advertise. A simple $5 ad on Craiglsist could make an advertisers phone ring for days. A single ad on escorts.com could fill a schedule for weeks. Then Eros got big, it became as good if not better than escorts.com quickly, most often attracting the most quality clients. Our Agency's used all 3, escorts., eros. and CL. At the time backpage was a shit site we didn't bother with... there were a FEW other sites we listed links to our own websites on, like southerngfe.com or openadultdirectory.com and a few others... more for SEO than anything else... they didn't bring much.. CL was all we needed. ECCIE was not big at all in our region then, so we never really used them. Then it all started to change… CL took down the Adult services section. Escorts.com was raided and shuttered. Backpage became king. I remember people paying just .25 cents to post an ad for a week on BP, then just days after CL closed it was $3? I had started working for Village Voice by then as a consultant, and was there when CL closed... I got calls from my partners... usually by 1pm we had booked a few calls in each city (we were in 3) and had taken several dozen calls asking prices... we had booked ZERO that day and taken less than 5 calls... ALL from our website and google searches... our CL ads had not made phones ring once... they kept testing the phones... they all worked. Then word came through from my office at BP that CL had pulled the plug... they put a big "CENSORED" label over the adult services tab... a few days later it was gone. After the smoke cleared, there was only a few places you really needed to be on... cityguidex.com, eros.com, ECCIE (in certain regions) and backpage. That was it. THere were a few other sites... and they were more regional... this is 2010/2011 I am talking about... The only place a escort REALLY needed to post an ad was backpage… if another site popped up, the rule of thumb was simple… if no other SW’s are posting there… don’t bother… its not worth it. Now lets be honest.. there are advertisers that could make a very nice living and book a lot of calls from just backpage... and there are the ones that would never could never... These were advertisers that had their own sites, charged upwards of 500/hr and did the fly me to you type stuff... very few advertisers doing 150h/h calls off backpage have websites... we all know what I am talking about if you have been around at all. During this time for the most part , Agency's in most citys started going out of business... this was for a few reasons... 1. the yellow pages DIED! Smart phones KILLED the yellow pages. NO ONE USES A PHONE BOOK ANYMORE!! It cost a min of $10k up front to put even a small ad in the yellow pages... the agency's that could and did had ruled the escort world since the 80's... if you were a sexworker you worked for an agency because you couldn't get calls otherwise...(generally speaking) suddenly CL and other sites like it made it so ANYone with a cell phone could run their own agency, or even better, go "independent" And the indys and the independents and the internet sites like CL and backpage killed the agency's. Clients looked at the math like this... lets say an agency charged $200/hr... the girl was usually getting a 50/50 split, so she took 100. They would then "charge" a tip of an avg of $100... so the girl got 200, the agency 100.. and the guy was out 300... but that same girl could post an ad saying 175/hr with NO upsell... and although yea... she made 25 less... she would book 10 times the calls and not have to split shit... guys wanted to deal direct to save and get more "bang" for their buck.. (pardon the pun) So the internet was suddenly swamped with independents... at about the same time CL was king and then died... it was a crazy time... suddenly all these independents need a place to advertise, because its back to the agency's (pimps in a lot of cases) if they cant get calls... very few were gonna start their own websites, and if they did... how do they drive traffic? Backpage filled the void. ECCIE grew as did a few other sites Again, I was working with them by now... and it was retarded. "Craigslist alternative" was one of the top google searched terms in the WORLD in sept 2010 when CL closed... think about that. Of course BP starts charging more... and more... and more. They offered more features.. charging for all of them... and now it was a crazier time... all the other sites are either crap or being shut down. Eros was super expensive, and wanted your DL licence and more... SO BP was king! But we all remember how that went... and come April of 2018.. BP is gone, and then the real shitshow started. Bedpage.com, Onebackapge.com, Ibackpage.com Ebackpage.com backpage.cl the site I helped start with the backpagecredits.com guys was yesbackpage.com, then skipthegames.com cityguidex.com slixa.com tryst.link there was some gator site out of Australia, afterdarkads.com, eros.com had a knock off.. DOZENS of sites and I cant remember how many others have popped up and died in the past year... its been insane. I consulted on afterdarkads.com for payment systems, and they are doing great. Others are dying. ECCIE is doing better than ever And ALL of the rules you thought you knew about advertising are gone. Since the demise of backpage, there are literally dozens of sites popping up all jockeying to be the next backpage. The truth is… it will never happen. Some will have more success than others, some will fold, some will remain… but the new reality is there are now be dozens of places to advertise. I helped the girl making verified vixens... she has already shut down for a few months because she is underfunded and cant market the site right. (she says she will be back... it was a GREAT site) The rule of thumb was that if you saw a site that you could advertise on, and there was no one else in your city/region... dont bother. ESPECIALLY if you had to pay... So now, when you find a new site, and there is just a few ads you figure are fake there… should you ignore it and move on? NO! advertising today is a different animal. An advertiser needs to have as many ads up in as many places as possible… and most importantly, needs to think and act like a client. We here in the industry knew an hour after backpage closed… we were searching for alternatives immediately. There are clients out there that look for an escort maybe 1 time a year on vacation, or the guy that found his regular SW’r on backpage 2 years ago… and now is looking for a new one… they are searching for “backpage alternative” or “backpage replacement” (according to google analytics those are the TOP search terms related to sex work and backpage since April 2018) they are searching craiglslist personals replacement, or "new backpage" ... You need to be on the sites that come up in those results, EVEN IF THERE IS NO ONE ELSE SMART ENOUGH TO POST AN AD THERE!!! The clients are searching using those terms…and dozens of others, and they are browsing the links they find… and they are not finding you! Why is that? You are not thinking like a client… you found bedpage… saw there was a ton of ads… and figured that if everyone else is posting there… I should as well. Bedpage used a bot to crawl backpage in the weeks before it closed, and copy/pasted the majority of ads it found to bedpage… MANY advertisers report getting calls and finding their ads posted on bedpage… and they did not create an account or post. MOST of the ads you are PAYING to compete with are fake... clients know it.. they are moving on from those sites FAST. Sites like bedpage use to be having lots of success… they had a LOT of posts, and word got around to advertisers fast… BUT THE CLIENTS DIDN’T GET THE WORD! Yes, dedicated sex mongers that search for escorts daily know… and the guys that spend time on the boards and in forums know.. but the MAJORITY of clients are the guys that MIGHT call one or 2 times a year… they have never heard of usasexguide.nl or the otherboards.com… they are doing something simple… typing in backpage… finding its gone… then going to google, and typing “backpage alternative”. And here is the next issue, Bedpage, ebackpage, ibackpage, yesbackpage… they all have a similar problem, they attract the WORST customers. The calls and texts looking for a $50 blow and go all come from sites like them. The guys that DO crawl through the dozens and dozens of fake ads end up just blasting texts to every phone they find (even tho you said no texts in the ad) 3 am msgs that say "hey" or even worse.. "blow me in my car for 50$" after demanding pics to "prove" you are real... Advertisers today need to get on as many sites as they can. Get on all of them... ESPECIALLY the ones with hardly any ads. The unfortunate byproduct will be you will get those shitty messages.. part of the price you must pay for being in this industry... Here is why: 1. Branding... Most of these clients are searching on dozens of sites for an escort... if they see you on afterdarkads.com, AND on tryst, AND then on eros., then AGAIN when they kick back to afterdarkads.com, AND then AGAIN when they find slixa.com ... and THEN they FINALLY decide to book.. was it really the ad on slixa that really did it? Or the fact they saw you everyplace and it helped him know you are real, not a fake ad? Was it the ease of finding your ad on a site like afterdarkads.com because they only had to sort through 5 or 6 ads? What was it that made him book? Do you REALLY think having just ONE ad on bedpage, because that's where everyone posts is the best idea? It was because he saw you over and over he was BRANDED and eventually booked. Branding is this, what do you clean your ears with? NO, not q-tips... its a cotton swab, you have been branded. WHat do you blow your nose with? NO, not kleenex... its a tissue... you are branded. Whats "The best part of wake-ing up.......? its WHAT in your cup... yea.. its coffee.. but you just said Folgers... BRANDING... get in front of ALL the clients as often as possible... BRAND them to think of you when they think of an escort. The MAJORITY of clients are searching for an escort or hire escorts just a few times a year... they have never heard of all these sites the way we have... a few years ago 1 ad on one site was all you needed... now escorts need 30 ads on 10 sites. Its the way it is.
Simple odds... there are 20+ new sites online... if you are on just 3 of them.. what are your odds that perfect client looking for a girl/guy just like you finds you? Be on all 20 and your odds are much better. There are plenty of clients seeking a sexworker or escort that are only finding escort sites like afterdarkads.com or slixa.com , etc right now for the first time... and in most cities there are just 1 or 2 ads... the bigger cities a few more... if you posted a free ad on there last week.. that you didn't even need bump or pay to feature... he WILL find you... BUT, if you are not there... he will end up moving on, maybe even searching a dozen other sites with barley any posts... maybe give up, search for an agency... go to a strip club book your competition.. who knows. What I DO know is that every time you post an ad on another site... you increase your odds dramatically that you are found. REMEMBER, these clients don't know all the sites... who knows what site they will end up on. And if you are NOT on the ones they find.. there is 1000% chance they call you.
A great way to booking more is to get a website. There are a lot of VERY inexpensive ways to post one.. many advertisers cant or don't have the resources or ability's... be very careful with the services promising escort websites for money. I am happy to walk you through some easy free steps that can get you on the right path, I will also build a simple free site, just cover the cost, The hosting I recommend will cost you about $10/month, the domain registration and privacy will be about $25 a year, for under $50 I will put a basic site online for you , and show you how to modify it and post to it form your phone. I want nothing for it... I am happy to help anyone in this industry. just PM me. Once you have one.. .LIST YOUR ESCORT WEBSITE ON ALL THE ESCORT SITES! Another thing to beware of, MANY reports claim that bedpage, aka ebackpage, aka, ibackpage, aka, onebackpage, aka icracker aka yesbackpage (all the same few guys in India and Bangladesh) have all been known to of given access to advertiser accounts to law enforcement resulting in several arrests. Escorts in NY, TX, and Co all report the same thing, when they were arrested, LE had access to their ad account, showing IP’s they posted from (leading one agency to the actual incall location they also posted ads from) payment methods and more. Be CAREFUL with what you post... use a VPN, do NOT use any payment method that can be connected to you, Tryst has a secure system it looks like and you can use btc or gift cards. Most of the other sites accepting credit/debit cards are at risk... if you are paying with a CC, GET A GIFT CARD like vanilla visa and pay cash for it... afterdarkads.com uses a payment site called adacredits.com and allows payment via many ways that hide your identity like gift cards, Bedpage does something similar but I worry its out of india... but do NOT use your personal amazon acct to buy an amazon card to buy credits from any escort advertisement site. Don't use your CC to buy a best buy card or target card to get an ad on bedpage. . If a site is asking for you to use a debit credit card, or worse upload an ID as proof of anything, you are taking a HUGE risk. eventually a lot of these sites are gonna get raided or closed. or hacked... ( I see rumors yesbackpage just got hacked by one of the owner siddiqs little jerkoff programmers thiefs... lol) whatever info they have stored is all sitting there waiting to be exploited. BE CAREFUL Use a VPN... ALWAYS. If you cant, get a burner smart phone from Walmart through straight talk.. DO NOT sign into your personal FB on that phone, or your reg email... you want that phone and everything on it to NEVER have any attachment to who you are. pay cash for it all and to reup monthly. INSTALL A VPN if you can. Ask for help here on how to do it.. your safety and freedom depend on this. Its not just the gov you are hiding from... its clients that have tech backgrounds. I will promise you.. there are VERY few advertisers out there, that if I wanted to, I could get your real name, address, phone, birth-date, and MUCH more. There are THOUSANDS of people out there like me... Laugh if you want but its true. At least I am a decent guy, I don't see sexworkers myself, not that I find anything wrong with it at all.. I am safe, you dont need worry about me, But we all know there are PLENTY of weirdos out there that will stalk you, harass you, and then there are the ones that want to hurt you. Yea, the gov will use your information to arrest you or fuck with you... but those scumbags are killers that will rape you and stick you in a dumpster... BE CAREFUL. BE SAFE. BE SMART. YOU NEED TO BE ADVERTISING A LOT AND OFTEN!!! Those days of 1 ad producing tons of results are OVER… unless backpage returns… you need to be posting a LOT… it is the new world we live in!! On MANY sites! tryst.link is a top result and is working hard to bring the traffic, they seem to care about advertisers. slixa is a great site but not a lot of results. you know the deal with most of the older backpage clones like bedpage. skip the games is REALLY solid. As I said I helped the girls that started afterdarkads.com, they like tryst care, are sexworkers themselves, and verify advertisers... you are not competing to post against fake ads on afterdarkads. They are doing a great job. Cityxguide is solid for the most part I can see, I hear that on the west coast they are killing it. There were a few guys from BP that went to work for them, I hear good things... You need to be on ALL of them and posting a LOT!! post 1 ad per day on EVERY single site that has daily posting EVEN IF YOU JUST POSTED THE ONLY AD YESTERDAY!!!! on sites like tryst with a profile, at a minimum 1 profile, its smart to have a second with dif pics and numbers... pics hiding a face, diff description... in one describe yourself as a sexy cute fun playful thing.. in the other describe yourself as a dominant sex machine... As sexworkers the best bet is to be a chameleon and adapt yourself to what the client is looking to pay for... HAVE A SCREENING PROCESS!!! Most high end advertisers with their own websites have extensive screening processes... go find them, read their requirements... what will work for you? Mimic them. Advertising after backpage is not as easy as it once was… it takes work… it takes INVESTING in yourself. EVERY dollar you spend advertising is an investment. Not enough money in your pocket? INVEST MORE! I hope you get something that helps you from this. It is all my opinions based on many years in this industry and seeing a lot. I was very successful advertising my own agency and learned a lot. I am happy to answer any questions I can. PM or ask away here! Again PLEASE, be careful and be safe!
BTC Fees amplified today by last night's difficulty adjustment. Current (peak of day) next-block fees are testing new highs.
Compounding Factors Causing the Fee Explosion Over the past 2 weeks, a large sum of SHA256 hashpower has come online as the rewards for mining in real-dollar value had been increasing. The increase over the past 2016 blocks was so great in fact that it caused an 11% jump in difficulty last night. To add to that, the price retreated back to the 2-week average meaning some hashpower has left after the price adjustment. You can see how far behind schedule the current block times are here. That has compounded to set new highs in sat/byte fees and has simultaneously escalated the price per transaction drastically While BTC blocks may be able to clear overnight when mining is running 10-20% above the expected block rate, it's pretty clear from history that every day has a peak usage that cannot be handled by the network. After readjustment, it looks like only the lull of the weekend can currently clear the backlog, and only just. I recommend checking Johoe's Mempool size in MB graph for a longer span. In the 3 month graph, you can really start to see each daily spike, weeks where the mempool only cleared on the weekend, and even a couple of weekends where the mempool didn't clear. So What is Each Blockchain Currently Capable Of? Current Segwit usage has been stagnant at around 40-45% for the past year now, but let's just say for argument's sake that segwit usage hits 100%. This represents a capacity increase of the BTC blockchain of only around 25%. That means that even if BTC hit perfect segwit usage, it could only handle around 500k transactions per day instead of 400k. This bottleneck does not exist on BCH. BCH can currently handle 16M blocks with no issue as proved by last year's stress-test and it should now be able to handle full 32MB blocks given recent parallelization improvements. The throughput of even 16MB blocks would allow for somewhere around an 8M TX/day average. Bitcoin Cash is absolutely equipped to deal with an order of magnitude more transactions than Bitcoin today while maintaining 1sat/byte fees. Blockchain technology can do so much more than BTC gives it credit for.
Hi all, new to cloud mining and researching at the moment. I was wondering whether anybody could share their experiences and things to consider regarding 'reinvesting' vs. profit taking. As I understand, retaining the same hash rate as the difficulty adjustment increases reduces your reward. Reinvesting your reward into greater hash power will merely keep you treading water in terms of your reward rate, and eat into your take home profits. Surely there comes a point where you decide to stop reinvesting and take the profit instead? Or am I correct in thinking that people reinvest to retain their hash power, with the expectation that the coin will be worth considerably more in the future and the profit can be taken by cancelling the reinvest option further down the line where the profits will be greater? Is my above logic correct? What other considerations are there? Are there reinvesting strategies that people use? Thanks in advance.
10% difficulty jump soon: Transact now if you can, before fees go up
Currently the mempool is pretty empty, so you can get in a transactions with low fees even though we have tons of transactions every day. This is in result of more miners coming online thanks to higher prices. Thus the network is currently mining 10% faster than before the last difficulty adjustment. This will result in a 10%+ difficulty increase starting Friday during the next difficulty adjustment. See difficulty estimate in real time here. After such difficulty increase the relative speed of mining will drop, and thus it will likely result in a mountain of transactions building up, increasing the tx fees. See the transactions and fees in real time here. So, if you have any transactions that you can do before Friday, for example consolidating funds, moving to segwit bech32, or opening LN channels, do it now. Here are some ideas why you should move to Bech32. If price continues to climb by the end of the week, we may see even more miners, and thus the low fees will continue.
I've been collecting some compression efficiency data on BCH mainnet blocks with Xthinner for the last 1.5 days, and thought I would share some results. Of the last 200 blocks, there were 13 instances in which the recipient was missing one or more transactions and had to fetch with a round trip, for a 6.5% fetch rate. I calculated the compression efficiency in 3 separate ways:
With all data sent by Xthinner, including the shortID segment, the missing transactions, the coinbase transaction, and the block header;
With the shortIDs, coinbase, and header, but not the missing transactions; and
With only the shortIDs.
The mean compression rates for these 201 blocks were as follows:
99.563% without cb+header+missing 99.385% with cb+header w/o missing 99.209% with everything
In terms of bits/tx, those numbers are:
14.021 bits/tx without cb+header+missing 19.721 bits/tx w cb+header w/o missing 25.348 bits/tx with everything
The average block size during this test was 327 tx/block or 131 kB/block. I expect these numbers to tend towards 12 bits/tx asymptotically as block sizes increase. These numbers were calculated using the sum of the Xthinner message sizes divided by the sum of the block sizes, rather than the mean of the individual blocks' compression rates. This means that my mean compression numbers are weighted by block size. In comparison, bissias reported yesterday that Graphene got a median compression (with everything) of 98.878% on these dinky mainnet BCH block sizes. Graphene does much better at large block sizes, though, getting up to 99.88% on the biggest blocks, which is about 2x-3x better than the best Xthinner can do. Except for the missing transactions, there were 0 errors decoding Xthinner messages. Specifically, of the last 201 blocks, there were 0 instances of Xthinner encoding too little information to disambiguate between transactions in the recipient's mempool, and there were 0 instances of checksum errors during decoding. (This is normal and expected for normal operation. In adversarial cases or extreme stress-test scenarios with desynced mempools, these numbers might go up, but if they do they only cause an extra round trip. The full dataset of 201 blocks (with lame formatting) can be found here. Astute observers might notice that this performance result is much better than what I first reported, in which around 75% of blocks had "missing" transactions. It turns out that these were actually decoding ambiguities caused by my encoder having an off-by-one error when finding the nearest mempool neighbor. Oopsies. Fixed. I also changed my test setup to have better and more realistic mempool synchrony. These two changes lowered the missing transaction rate to about 6.5% of blocks. If anyone wants to dig into the code or play around with it, you can find it here. Keep in mind that there may still be remote crash or remote code execution vulnerabilities, so don't run this code on anything you want to not get hacked. Edit: I think I prefer the alternate formulation for compression ratios in which 0% is the ideal. Using that formula, Xthinner was able to compress the blocks down to an average of
0.437% without cb+header+missing 0.615% with cb+header w/o missing 0.781% with everything
of their original size, whereas Graphene was able to get to1.122% on the median block, and 0.117% on the best block. Edit2: If we examine only the 5 blocks with more than 1000 tx in them, we get:
Fetched transactions 0 of 5 times Mean compression: 0.390% without cb+header 0.420% with everything 13.285 bits/tx average 12.330 bits/tx without coinbase+header
Edit4: It's been almost two weeks, and I now have 197 blocks over 1k tx in the dataset:
Fetched transactions 9 of 107 times 0 ambiguities, 0 checksum errors Mean compression: 99.563% without cb+header+missing 99.518% with cb+header w/o missing 99.500% with everything 14.522 bits/tx average with missing, 14.017 bits/tx average without 12.701 bits/tx without coinbase+header
This FAQ and information thread serves to inform both new and existing users about common Bitcoin topics that readers coming to this Bitcoin subreddit may have. This is a living and breathing document, which will change over time. If you have suggestions on how to change it, please comment below or message the mods. What is /btc? The /btc reddit community was originally created as a community to discuss bitcoin. It quickly gained momentum in August 2015 when the bitcoin block size debate heightened. On the legacy /bitcoin subreddit it was discovered that moderators were heavily censoring discussions that were not inline with their own opinions. Once realized, the subreddit subscribers began to openly question the censorship which led to thousands of redditors being banned from the /bitcoin subreddit. A large number of redditors switched to other subreddits such as /bitcoin_uncensored and /btc. For a run-down on the history of censorship, please read A (brief and incomplete) history of censorship in /bitcoin by John Blocke and /Bitcoin Censorship, Revisted by John Blocke. As yet another example, /bitcoin censored 5,683 posts and comments just in the month of September 2017 alone. This shows the sheer magnitude of censorship that is happening, which continues to this day. Read a synopsis of /bitcoin to get the full story and a complete understanding of why people are so upset with /bitcoin's censorship. Further reading can be found here and here with a giant collection of information regarding these topics. Why is censorship bad for Bitcoin? As demonstrated above, censorship has become prevalent in almost all of the major Bitcoin communication channels. The impacts of censorship in Bitcoin are very real. "Censorship can really hinder a society if it is bad enough. Because media is such a large part of people’s lives today and it is the source of basically all information, if the information is not being given in full or truthfully then the society is left uneducated [...] Censorship is probably the number one way to lower people’s right to freedom of speech." By censoring certain topics and specific words, people in these Bitcoin communication channels are literally being brain washed into thinking a certain way, molding the reader in a way that they desire; this has a lasting impact especially on users who are new to Bitcoin. Censoring in Bitcoin is the direct opposite of what the spirit of Bitcoin is, and should be condemned anytime it occurs. Also, it's important to think critically and independently, and have an open mind. Why do some groups attempt to discredit /btc? This subreddit has become a place to discuss everything Bitcoin-related and even other cryptocurrencies at times when the topics are relevant to the overall ecosystem. Since this subreddit is one of the few places on Reddit where users will not be censored for their opinions and people are allowed to speak freely, truth is often said here without the fear of reprisal from moderators in the form of bans and censorship. Because of this freedom, people and groups who don't want you to hear the truth with do almost anything they can to try to stop you from speaking the truth and try to manipulate readers here. You can see many cited examples of cases where special interest groups have gone out of their way to attack this subreddit and attempt to disrupt and discredit it. See the examples here. What is the goal of /btc? This subreddit is a diverse community dedicated to the success of bitcoin. /btc honors the spirit and nature of Bitcoin being a place for open and free discussion about Bitcoin without the interference of moderators. Subscribers at anytime can look at and review the public moderator logs. This subreddit does have rules as mandated by reddit that we must follow plus a couple of rules of our own. Make sure to read the /btc wiki for more information and resources about this subreddit which includes information such as the benefits of Bitcoin, how to get started with Bitcoin, and more. What is Bitcoin? Bitcoin is a digital currency, also called a virtual currency, which can be transacted for a low-cost nearly instantly from anywhere in the world. Bitcoin also powers the blockchain, which is a public immutable and decentralized global ledger. Unlike traditional currencies such as dollars, bitcoins are issued and managed without the need for any central authority whatsoever. There is no government, company, or bank in charge of Bitcoin. As such, it is more resistant to wild inflation and corrupt banks. With Bitcoin, you can be your own bank. Read the Bitcoin whitepaper to further understand the schematics of how Bitcoin works. What is Bitcoin Cash? Bitcoin Cash (ticker symbol: BCH) is an updated version of Bitcoin which solves the scaling problems that have been plaguing Bitcoin Core (ticker symbol: BTC) for years. Bitcoin (BCH) is just a continuation of the Bitcoin project that allows for bigger blocks which will give way to more growth and adoption. You can read more about Bitcoin on BitcoinCash.org or read What is Bitcoin Cash for additional details. How do I buy Bitcoin? You can buy Bitcoin on an exchange or with a brokerage. If you're looking to buy, you can buy Bitcoin with your credit card to get started quickly and safely. There are several others places to buy Bitcoin too; please check the sidebar under brokers, exchanges, and trading for other go-to service providers to begin buying and trading Bitcoin. Make sure to do your homework first before choosing an exchange to ensure you are choosing the right one for you. How do I store my Bitcoin securely? After the initial step of buying your first Bitcoin, you will need a Bitcoin wallet to secure your Bitcoin. Knowing which Bitcoin wallet to choose is the second most important step in becoming a Bitcoin user. Since you are investing funds into Bitcoin, choosing the right Bitcoin wallet for you is a critical step that shouldn’t be taken lightly. Use this guide to help you choose the right wallet for you. Check the sidebar under Bitcoin wallets to get started and find a wallet that you can store your Bitcoin in. Why is my transaction taking so long to process? Bitcoin transactions typically confirm in ~10 minutes. A confirmation means that the Bitcoin transaction has been verified by the network through the process known as mining. Once a transaction is confirmed, it cannot be reversed or double spent. Transactions are included in blocks. If you have sent out a Bitcoin transaction and it’s delayed, chances are the transaction fee you used wasn’t enough to out-compete others causing it to be backlogged. The transaction won’t confirm until it clears the backlog. This typically occurs when using the Bitcoin Core (BTC) blockchain due to poor central planning. If you are using Bitcoin (BCH), you shouldn't encounter these problems as the block limits have been raised to accommodate a massive amount of volume freeing up space and lowering transaction costs. Why does my transaction cost so much, I thought Bitcoin was supposed to be cheap? As described above, transaction fees have spiked on the Bitcoin Core (BTC) blockchain mainly due to a limit on transaction space. This has created what is called a fee market, which has primarily been a premature artificially induced price increase on transaction fees due to the limited amount of block space available (supply vs. demand). The original plan was for fees to help secure the network when the block reward decreased and eventually stopped, but the plan was not to reach that point until some time in the future, around the year 2140. This original plan was restored with Bitcoin (BCH) where fees are typically less than a single penny per transaction. What is the block size limit? The original Bitcoin client didn’t have a block size cap, however was limited to 32MB due to the Bitcoin protocol message size constraint. However, in July 2010 Bitcoin’s creator Satoshi Nakamoto introduced a temporary 1MB limit as an anti-DDoS measure. The temporary measure from Satoshi Nakamoto was made clear three months later when Satoshi said the block size limit can be increased again by phasing it in when it’s needed (when the demand arises). When introducing Bitcoin on the cryptography mailing list in 2008, Satoshi said that scaling to Visa levels “would probably not seem like a big deal.” What is the block size debate all about anyways? The block size debate boils down to different sets of users who are trying to come to consensus on the best way to scale Bitcoin for growth and success. Scaling Bitcoin has actually been a topic of discussion since Bitcoin was first released in 2008; for example you can read how Satoshi Nakamoto was asked about scaling here and how he thought at the time it would be addressed. Fortunately Bitcoin has seen tremendous growth and by the year 2013, scaling Bitcoin had became a hot topic. For a run down on the history of scaling and how we got to where we are today, see the Block size limit debate history lesson post. What is a hard fork? A hard fork is when a block is broadcast under a new and different set of protocol rules which is accepted by nodes that have upgraded to support the new protocol. In this case, Bitcoin diverges from a single blockchain to two separate blockchains (a majority chain and a minority chain). What is a soft fork? A soft fork is when a block is broadcast under a new and different set of protocol rules, but the difference is that nodes don’t realize the rules have changed, and continue to accept blocks created by the newer nodes. Some argue that soft forks are bad because they trick old-unupdated nodes into believing transactions are valid, when they may not actually be valid. This can also be defined as coercion, as explained by Vitalik Buterin. Doesn't it hurt decentralization if we increase the block size? Some argue that by lifting the limit on transaction space, that the cost of validating transactions on individual nodes will increase to the point where people will not be able to run nodes individually, giving way to centralization. This is a false dilemma because at this time there is no proven metric to quantify decentralization; although it has been shown that the current level of decentralization will remain with or without a block size increase. It's a logical fallacy to believe that decentralization only exists when you have people all over the world running full nodes. The reality is that only people with the income to sustain running a full node (even at 1MB) will be doing it. So whether it's 1MB, 2MB, or 32MB, the costs of doing business is negligible for the people who can already do it. If the block size limit is removed, this will also allow for more users worldwide to use and transact introducing the likelihood of having more individual node operators. Decentralization is not a metric, it's a tool or direction. This is a good video describing the direction of how decentralization should look. Additionally, the effects of increasing the block capacity beyond 1MB has been studied with results showing that up to 4MB is safe and will not hurt decentralization (Cornell paper, PDF). Other papers also show that no block size limit is safe (Peter Rizun, PDF). Lastly, through an informal survey among all top Bitcoin miners, many agreed that a block size increase between 2-4MB is acceptable. What now? Bitcoin is a fluid ever changing system. If you want to keep up with Bitcoin, we suggest that you subscribe to /btc and stay in the loop here, as well as other places to get a healthy dose of perspective from different sources.

I literally have tens of thousands of dollars in top-shelf hardware, looking to repurpose some before selling on eBay to build a NAS system, possibly a dedicated firewall device as well. o_O
Q1) What will you be doing with this PC? Be as specific as possible, and include specific games or programs you will be using.** A1) This will be a dedicated NAS system for my home network. As such, I'm looking to have it: - Host ##TB's of 720, 1080 & up resolution Movies and TV Shows I'm about to begin ripping from a MASSIVE DVD & Blueray collection I have. - My kids are big on Minecraft. I understand it's possible to host your own "worlds" (or whatever they call the maps you can build) on your own "server". I think it would be pretty neat to offer them (& their friends - if can be done 'safely/securely') their own partition on one of my NAS HDD's. - I also have accounts with a couple diff VPN companies... I understand it's possible (?) to sync said VPN's with a NAS, this might be a more relative topic on the next point/purpose... - I'd like to be able to remotely link to this NAS for when I travel overseas and want to stream at my temp location from my house/this NAS. ______________________ Q2) What is your maximum budget before rebates/shipping/taxes?** * A2) Here's where I make matters more complicated than most others would... I've been an advocate for Bitcoin and crypto-currencies in general since 2013. I invested in a small mining outfit back in 2014 (strictly Bitcoin/ASIC's). One of my buddies is the President of a large-scale mining operation (foreign and domestic) and he convinced me to dabble in the GPU mining-space. I made my first hardware purchase in Q4, 2017 and launched a small-scale GPU-Farm in my house since then. I had the rigs mining up until Q3 of 2018 (not cost-efficient to keep on, especially living in SoFlo) and since then, the hardware's been collecting dust (& pissing off my family members since they lost access to 3X rooms in the house - I won't let anyone go near my gear). One of my New Years Resolutions for 2019 was to clear out the house of all my mining equipment so that's all about to go up on eBay. So "budget" is relative to whatever I "MUST" spend if I can't repurpose any of the parts I already have on hand for this build... (Anyone having something I "need" and is looking to barter for one of the items I'll list later on in here, LMK). ______________________ Q3) When do you plan on building/buying the PC? Note: beyond a week or two from today means any build you receive will be out of date when you want to buy.** A3) IMMEDIATELY! :) ______________________ Q4) What, exactly, do you need included in the budget? (ToweOS/monitokeyboard/mouse/etc\)** A4) Well I had a half-assed idea approximately 1 year ago that it might be wise to build a bunch of 'gaming rigs' to sell on eBay with my intended repurposed mining hardware so I went on a shopping spree for like 6 months. That said; I've got a plethora of various other components that aren't even unboxed yet. 90% of the items I've purchased for this additional project were items that were marked down via MIR (mail-in-rebates) & what-not...
AFAIK, there are only 3X items I absolutely do not have which I 'MUST' find. Those would be - 1) Motherboard which accepts "ECC RAM". 2) CPU for said MOBO. 3) Said "ECC RAM".\*
______________________ Q5) Which country (and state/province) will you be purchasing the parts in? If you're in US, do you have access to a Microcenter location?** A5) I'm located in Southwest Florida. No Microcenter's here. Best Buy is pretty much my only option although I am a member of Newegg, Amazon & Costco if that makes any difference? ______________________ Q6) If reusing any parts (including monitor(s)/keyboard/mouse/etc), what parts will you be reusing? Brands and models are appreciated.** A6) In an attempt to better clean up this Q&A, I'm going to list the items I have on-hand at the end of this questionnaire in-case passers-by feel like this might be a TLDR.* (Scroll to the bottom & you'll see what I mean). ______________________ Q7) Will you be overclocking? If yes, are you interested in overclocking right away, or down the line? CPU and/or GPU?** A7) I don't think that's necessary for my intended purpose although - I'm not against it if that helps & FWIW, I'm pretty skilled @ this task already (it's not rocket science). ______________________ Q8) Are there any specific features or items you want/need in the build? (ex: SSD, large amount of storage or a RAID setup, CUDA or OpenCL support, etc)** A8) As stated in A4; ECC RAM is non-negotiable... RAID seems like a logical application here as well. - This will predominantly be receiving commands from MacOS computers. I don't think that matters really but figured it couldn't hurt to let you guys know.\* - I'd also be quite fond of implementing "PFSENSE" (or something of that caliber) applied to this system so I could give my Netgear Nighthawks less stress in that arena, plus my limited understanding of PFSENSE is that it's ability to act as a firewall runs circles around anything that comes with consumer-grade Wi-Fi routers (like my Nighthawks). Just the same, I'm open to building a second rig just for the firewall.\* - Another desirable feature would be that it draws as little electricity from the wall as possible. (I'm EXTREMELY skilled in this arena. I have "Kill-A-Watts" to test/gauge on, as well as an intimate understanding of the differences between Silver, Gold, Platinum and Titanium rated PSU's. As well as having already measured each of the PSU's I have on-hand and taken note of the 'target TDP draw' ("Peak Power Efficiency Draw") each one offers when primed with X amount of GPU's when I used them for their original purpose.\* - Last, but not least, sound (as in noise created from the rig). I'd like to prop this device up on my entertainment center in the living room. I've (almost) all of the top-shelf consumer grade products one could dream of regarding fans and other thermal-related artifacts. - Almost forgot; this will be hosting to devices on the KODI platform (unless you guys have better alternative suggestions?) ______________________ Q9) Do you have any specific case preferences (Size like ITX/microATX/mid-towefull-tower, styles, colors, window or not, LED lighting, etc), or a particular color theme preference for the components?** A9) Definitely! Desired theme would be WHITE. If that doesn't work for whatever reason, black or gray would suffice. Regarding "Case Size". Nah, that's not too important although I don't foresee a mini-ITX build making sense if I'm going to be cramming double digit amounts of TB in the system, Internal HDD's sounds better than a bunch of externals plugged in all the USB ports. ______________________ Q10) Do you need a copy of Windows included in the budget? If you do need one included, do you have a preference?** A10) I don't know. If I do need a copy of Windows, I don't have one so that's something I'll have to consider I guess. I doubt that's a necessity though. ______________________ ______________________ ______________________ **Extra info or particulars:*\* AND NOW TO THE FUN-STUFF... Here's a list of everything (PARTS PARTS PARTS) I have on-hand and ready to deploy into the wild &/or negotiate a trade/barter with: CASES - Corsair Carbide Series Air 540 Arctic White (Model# Crypto-Currency-9011048-WW) - (Probably my top pick for this build).

CLC 240 (240mm Water-cooled system CRYORIG - Cryorig C7 Cu (Low-Profile Copper Edition*) A few other oversized CPU cooling systems I forget off the top of my head but a CPU cooler is a CPU cooler after comparing to the previous 3 models I mentioned. I almost exclusively am using these amazing "Innovation Cooling Graphite Thermal Pads" as an alternative to thermal paste for my CPU's. They're not cheap but they literally last forever. NZXT - Sentry Mesh Fan Controller ______________________ POWER SUPPLIES (PSU's) - BeQuiet 550W Straight Power 11 (GOLD) EVGA - 750P2 (750W, Platinum) 850P2 (850W, Platinum) 750T2 (750W, TITANIUM - yeah baby, yeah) ROSEWILL - Quark 750W Platinum Quark 650W Platinum SEASONIC - Focus 750W Platinum ______________________ STORAGE - HGST Ultrastar 3TB - 64mb Cache - 7200RPM Sata III (3.5) 4X Samsung 860 EVO 500GB SSD's 2X Team Group L5 LITE 3D 2.5" SSD's 480GB 2X WD 10TB Essential EXT (I'm cool with shucking) + 6X various other external HDD's (from 4-8TB) - (Seagate, WD & G-Drives) ______________________ Other accessories worth mentioning - PCI-E to 4X USB hub-adapter (I have a dozen or so of these - might not be sufficient enough &/or needed but again, 'worth mentioning' in case I somehow ever run out of SATA & USB ports and have extra external USB HDD's. Although, I'm sure there would be better suited components if I get to that point that probably won't cost all that much). ______________________ ______________________ ______________________ Needless to say, I have at least 1X of everything mentioned above. In most all cases, I have multiples of these items but obviously won't be needing 2X CPU's, Cases, etc... Naturally, I have GPU's. Specifically; At least 1X of every. Single. NVIDIA GTX 1070 TI (Yes, I have every variation of the 1070 ti made by MSI, EVGA and Zotac. The only brand I don't have is the Gigabyte line. My partners have terrible experience with those so I didn't even bother. I'm clearly not going to be needing a GPU for this build but again, I'm cool with discussing the idea of a barter if anyone reading this is in the market for one. I also have some GTX 1080 TI's but those are already spoken for, sorry. It's my understanding that select CPU's I have on this list are ECC Friendly and AFAIK, only 1 of my MOBO's claims to be ECC Friendly (The ASROCK AB350M PRO4), but for the life of me, I can't find any corresponding forums that confirm this and/or direct me to a listing where I can buy compatible RAM. Just the same, if I go w/ the ASROCK MOBO, that means I'd be using one of the Ryzens. Those are DEF. power hungry little buggers. Not a deal-breaker, just hoping to find something a little more conservative in terms of TDP. In closing, I don't really need someone to hold my hand with the build part as much as figuring out which motherboard, CPU and RAM to get. Then I'm DEFINITELY going to need some guidance on what OS is best for my desired purpose. If building 2X Rigs makes sense, I'm totally open to that as well... Rig 1 = EPIC NAS SYSTEM Rig 2 = EPIC PFSENSE (or the like) DEDICATED FIREWALL Oh, I almost forgot... The current routers I'm using are... 1X Netgear Nighthawk 6900P (Modem + Router) 1X Netgear Nighthawk X6S (AC 4000 I believe - Router dedicated towards my personal devices - no IoT &/or Guests allowed on this one) 1X TP-Link Archer C5 (Router). Total overkill after implementing the Nighthawks but this old beast somehow has the best range, plus it has 2X USB ports so for now, it's dedicated towards my IoT devices. ---- I also have a few other Wi-Fi routers (Apple Airport Extreme & some inferior Netgear's but I can only allocate so many WiFi Routers to so many WiFi channels w/out pissing off my neighbors) On that note, I have managed to convince my neighbors to let me in their house/WiFi configuration so we all have our hardware locked on specific, non-competing frequencies/channels so everyone's happy. :) Please spare me the insults as I insulted myself throughout this entire venture. Part of why I did this was because when I was a kid, I used to fantasize about building a 'DREAM PC' but could never afford such. To compensate for this deficiency, I would actually print out the latest and greatest hardware components on a word document, print the lists up & tape to wall (for motivation). I was C++ certified at the age of 14 and built my first PC when I was 7. At the age of 15 I abandoned all hope in the sector and moved on to other aspirations. This entire ordeal was largely based off me finally fulfilling a childhood fantasy. On that note = mission accomplished. Now if I'm actually able to fulfill my desires on this post, I'm definitely going to feel less shitty about blowing so much money on all this stuff over the last couple years. TIA for assisting in any way possible. Gotta love the internets! THE END. :) EDIT/UPDATE (5 hours after OP) - My inbox is being inundated with various people asking for prices and other reasonable questions about my hardware being up for sale. Not to be redundant but rather to expound on my previous remarks about 'being interested in a bartetrade' with any of you here... I did say I was going to sell my gear on eBay in the near future, I also said I wanted to trade/barter for anything relative to helping me accomplish my OP's mission(s). I'm not desperate for the $$$ but I'm also not one of those people that likes to rip other people off. That said; I value my time and money invested in this hardware and I'm only willing to unload it all once I've established I have ZERO need for any of it here in my home first. Hence my writing this lengthy thread in an attempt to repurpose at least a grand or two I've already spent. One of the most commonly asked questions I anticipate receiving from interested bodies is going to be "How hard were you on your hardware?" Contrary to what anyone else would have probably done in my scenario which is say they were light on it whether they were or weren't, I documented my handling of the hardware, and have no problem sharing such documentation with verified, interested buyers (WHEN THE TIME COMES) to offer you guys peace of mind. I have photo's and video's of the venture from A-Z. I am also obliged to provide (redacted) electricity bill statements where you can correlate my photo's (power draw on each rig), and also accurately deduct the excess power my house consumed with our other household appliances. Even taking into consideration how much (more) I spent in electricity from keeping my house at a constant, cool 70-72F year-round (via my Nest thermostat). Even without the rigs, I keep my AC @ 70 when I'm home and for the last 1.5-2 years, I just so happened to spend 85% of my time here at my house. When I would travel, I'd keep it at 72 for my wife & kids. Additionally; I had each GPU 'custom' oveunderclocke'd (MSI Afterburner for all GPU's but the EVGA's).* I doubt everyone reading this is aware so this is for those that don't.... EVGA had the brilliant idea of implementing what they call "ICX technology" in their latest NVIDIA GTX GPU's. The short(est) explanation of this "feature" goes as follows: EVGA GPU's w/ "ICX 9 & above" have EXTRA HEAT/THERMAL SENSORS. Unlike every other GTX 1070 ti on the market, the one's with this feature actually have each of 2/2 on-board fans connected to individual thermal sensors. Which means - if you were to use the MSI Afterburner program on one of these EVGA's and create a custom fan curve for it, you'd only be able to get 1/2 of the fans to function the way intended. The other fan simply would not engage as the MSI Afterburner software wasn't designed/coded to recognize/ communicate with an added sensor (let alone sensor'S). This, in-turn, would likely result in whoever's using it the unintended way having a GPU defect on them within the first few months I'd imagine... Perhaps if they had the TDP power settings dumbed down as much as I did (60-63%), they might get a year or two out of it since it wouldn't run as near as hot, but I doubt any longer than that since cutting off 50% of the cooling system on one of these can't be ignored too long, surely capacitors would start to blow and who knows what else... (Warning = RANT) Another interesting side-note about the EVGA's and their "Precision-X" OveUnderclocking software is that it's designed to only recognize 4X GPU's on a single system. For miners, that's just not cool. My favorite builds had 8X and for the motherboards that weren't capable of maintaining stable sessions on 8, I set up with 6X. Only my EVGA Rigs had 3 or 4X GPU's dedicated to a single motherboard. Furthermore, and as stated in an earlier paragraph, (& this is just my opinion) = EVGA SOFTWARE SUCKS! Precision X wasn't friendly with every motherboard/CPU I threw at it and their extension software for the CLC Close-Loop-Cooling/ CPU water-coolers simply didn't work on anything, even integrating into their own Precision-X software. The amount of time it took me to finally find compatible matches with that stuff was beyond maddening. (END RANT). Which leads me to my other comments on the matter. That's what I had every single 1070 ti set at for TDP = 60-63%. Dropping the power load that much allowed me to bring down (on average) each 1070 ti to a constant 110-115W (mind you, this is only possible w/ "Titanium" rated PSU's, Platinum comes pretty damn close to the Titanium though) while mining Ethereum and was still able to maintain a bottom of 30 MH/s and a ceiling of 32 MH/s. Increasing the TDP to 80, 90, 100% or more only increased my hashrates (yields) negligibly, like 35-36 MH/s TOPS, which also meant each one was not only pulling 160-180W+ (Vs. the aforementioned 115'ish range), it also meant my rigs were creating a significantly greater amount of heat! Fortunately for the GPU's and my own personal habits, I live in South Florida where it's hot as balls typically, last winter was nothing like this one. Increasing my yields by 10-15% didn't justify increasing the heat production in my house by >30%, nor the added electricity costs from subjecting my AC handlers to that much of an extra work-load. For anyone reading this that doesn't know/understand what I'm talking about - after spending no less than 2-3 hours with each. and. every. one. I didn't play with the settings on just one and universally apply the settings to the rest. I found the 'prime' settings and documented them with a label-maker and notepad. Here's the math in a more transparent manner: *** I NEVER LET MY GPU's BREACH 61C, EVER. Only my 8X GPU rigs saw 60-61 & it was the ones I had in the center of the build (naturally). I have REALLY high power fans (used on BTC ASIC MINERS) that were sucking air from those GPU's which was the only way I was able to obtain such stellar results while mining with them. **\* Mining at "acceptable" heat temps (not acceptable to me, but most of the internet would disagree = 70C) and overclocking accordingly brings in X amount of yields per unit. = 'Tweaking' (underclocking) the GPU's to my parameters reduced my yield per unit from -10-15%, but it SAVED me well over 30-35% in direct electricity consumption, and an unknown amount of passive electricity consumption via creating approximately 20%+ less heat for my AC handler to combat. I say all this extra stuff not just for anyone interested in mining with their GPU's, but really to answer (in-depth) the apparent questions you people are asking me in PM's. Something else that should help justify my claims of being so conservative should be the fact I only have/used "Platinum and Titanium" rated PSU's. Heat production, power efficiency and longevity of the hardware were ALWAYS my top priority.* . I truly thought Crypto would continue to gain and/or recover and bounce back faster than it did. If this project had maintained positive income for 12 months+, I'd have expanded one of our sites to also cater to GPU mining on a gnarly scale. Once I have my NAS (& possibly 2nd rig for the firewall) successfully built, I'll be willing/able to entertain selling you guys some/all of the remaining hardware prior to launching on eBay. If there's something you're specifically looking for that I listed having, feel free to PM me with that/those specific item(s). Don't count on an immediate response but what you can count on is me honoring my word in offering whoever asks first right of refusal when the time comes for me to sell this stuff. Fortunately for me, PM's are time-stamped so that's how I'll gauge everyone's place in line. I hope this extra edit answers most of the questions you guys wanted to have answered and if not, sorry I guess. I'll do my best to bring light to anything I've missed out on after I realize whatever that error was/is. The only way anyone is getting first dibs on my hardware otherwise is if they either offer compelling insight into my original questions, or have something I need to trade w/. THE END (Round#2)
