1  Bitcoin / Electrum / What happened to the "Addresses" tab!? on: October 24, 2016, 06:56:35 PM
Hi everyone! as the title suggest, i'm baffled it got removed in the last stable update, why was this decision made? is there a way to bring it back again? (i used a lot to freeze some addys, and to use "Send from" for certain transactions).
2  Economy / Securities / [ANN][IPO] RarePepe.party, TCG + RPG Game crowdfunding with Counterparty shares on: October 10, 2016, 01:39:14 AM
Hi everyone, today i've just started this crowdfund for the RarePepe.party game, which will be a Trading Card Game + Role Playing Game based on the recent craze around Rare Pepe cards.

The business proposal document is over at my google drive and you can buy shares over at the Counterparty Decentralized Exchange (Counterwallet.io is one of them).

There's a teaser video showing up on our site, and there's also a telegram channel and twitter account for the game for you all to connect with us. Here's also a good place to communicate though.

As always, this is not financial advice, do your own due dilligence regarding ANY kind of investment.

6  Economy / Computer hardware / Anyone selling FPGA Modules/miners? on: February 27, 2016, 03:15:43 AM
As the subject says, back on 2012-2013 FPGA mining was all the rage, and i would like to know if anyone is selling any of those miners at entry-level prices? I'm considering starting some experiments with several ideas, and i want to synthesize my own cores and test on for real.

If anyone has a ZTex or a Cairnsmore1, i would like to know how much are you willing to get to part ways with it (a price that could benefit both of us would be great).
7  Economy / Services / [MINING][LOTTO] Mine with ~21.8 TH/s (19x S5) on: September 03, 2015, 02:29:47 PM
Hello peeps!

I have 19x S5 units currently mining with "almost free" electricity and i tought "everyone deserves a day of almost free mining"!

So i tought i'll open up a lotto for peeps to have at least 1 day of ~21.8 TH/s won with a little investment.



To enter the lotto, you simply send 0.01 BTC to 131pgA7KdtEqeTvD32xxdTgPrT7yrLQRxr and post a message here with the TXID (if two people claim the same TXID i'll require a signed message, so be sure to use an address you control). If you want more "tickets" you can send them in one transaction, multiplying by the number of tickets you want (don't send fractional amounts, i'll round down them).

When we hit 11pm on my time zone (-4:30 UTC) this friday, i'll create a list with the usernames of the entries and randomize them with random.org; the first entry on the list will be the winner.

The winner will be announced here and i'll be contacting them via PM to get the connection details. Once i get the details and setup all the miners i'll be starting the countdown timer.

All this process will be manual, if this catches on and becomes popular i'll be automating it.


Some figures:

  • Amount of miners: 19
  • Hashrate of each miner: ~1.155 TH/s
  • Total aprox. Hashrate: 21.8 TH/s (Actual figure, result of the setup i have)
  • Aprox. earnings from a 24 hours period at current difficulty: 0.19 BTC (19x the cost of the ticket)

The aprox. earnings takes into account internet slow-downs and rejects. There can be power failures and i'll be not held liable of those. I will compensate the power failures by granting additional time depending on the length of the aforementioned failure. I shall not be held liable of pool downtime or any other failure not related to power failures or internet connection dropping out.

If there are not enough participants, i'll make arrangements to return the proceedings.

This is my current hashrate on Slush's pool:

9  Bitcoin / Hardware / Why haven't we seen PDIP chips the traditional hobby DIY guy could use? on: July 21, 2015, 04:39:04 PM
Honest question, why not manufacturers?

You know what would be cool, allowing people to build their own miners, not only going crazy doing devices but creating a name around chip fabrication!

I know most manufacturers are trying to get a quick buck over the mining business, but it seems Blockchain techs are here to stay, so why not get on the forefront of this wave and be THE hobby manufacturer for PDIP mining asics?

And with PDIP i really mean any DIP chip... c'mon... it shouldn't be THAT hard to crank one out.
10  Bitcoin / Mining / Bitcoin Mine opportunity with ultra-cheap electricity on: July 16, 2015, 04:14:38 AM
I've been studying my local real-state market, and prices have been going lower lately.

I'm currently considering starting a project for a mining farm that will have approximate capacity of 7.5 MW.

Considering my past experiences with mining on my country, adding human resource costs (guards, technicians to setup miners, cleaning personell), electricity and internet costs, i calculate that hosting 1 KW on that mine would cost less than $10/KWh.

I've found a real-state lot on a nice place of the capital city that would fit a building with around 200 individual "shops" (being data-center oriented, there wouldn't be anyone around walking besides building employees) of ~20 sq meters with common air extraction and emergency CO2 extinguishers, with 36KW lots. I could provide all the man power necessary to keep running the place 24/7.

Is there any interest on this kind of endeavors? Would anyone be interested in investing on these kind of real-state on my country?

Also, i'm not interested on taking money atm, just knowing if people would be interested so i can develop the project and get costs down to reality to evaluate feasibility.

Some quick numbers: 36 KW worth of S5 would be ~69TH/s * 200 locations, 13.8 PH/s. Running 13.8 PH/s would cost south of $72k USD (with all non-electricity costs included).
11  Economy / Auctions / [WTS][Auction] Prypto.us for sale on: December 23, 2014, 07:37:05 PM
I've currently setup a mini blog to state some facts, i do want to sell this domain, i was going to do a lot of things with it but i'm rather short on time atm and it would be a huge opportunity for someone wanting to sell a lot of prepaid cards on the US.

http://www.prypto.us/

I'm starting the auction with the minimum bid of 0.1BTC (0.1BTC == hold the domain). I've registered it through GoDaddy, so you (and probably the escrow, if you have less reputation than me on btctalk) need to be registered on GoDaddy to accept the domain transfer in fast fashion.

Contact me here, via twitter @johnvillarz or the other methods on the page to make an offer.

Good luck everyone! Smiley

Rules:
  • Same amount offers will belong to the first person to offer on that bracket.
  • Minimum increments of 0.1btc, if your offer is less than 0.1btc from the previous offer, it will be silently ignored
  • If you have less reputation than me, you have to send BTC first, then i transfer the domain
  • If you have more reputation than me, we can pm each other the terms of the exchange

14  Alternate cryptocurrencies / Altcoin Discussion / [RANT] Get your s**t togheter altcoin developers! or a guide to brand your coins on: July 05, 2014, 04:00:55 PM
Warning: Rude language, if you're sensitive just don't read...

Yes, as you read it... you're doing an awful job for us, service developers, Why you ask? Here, lemme make a list for you all to digest easily:

  • 1.- Branding guidelines:This is one of the most overlooked facts of most altcoins. Heck, i have only found ONE (yes, just one) altcoin with branding guidelines, and it is a pityful job of branding guidelines. What do you need for a branding guideline? you ask... at least the following: Coin colors with hex values and if possible pantone colors too; font face with a download of the TTF, OTF or WOFF; SVG and AI logos, along with the PNG. There's a lot of things to do, but leave that to a professional.
  • 2.- Home Pages that load fast and don't bog down most peoples' CPU: Most DOMs of the most popular pages are awful, and they take FOREVER (in internet terms) to load. Run your page through a 512mb ram/1 core virtual box instance running chrome and you'll understand.
  • 3.- URI HANDLING: "Gooby plz, rly?" no correct URI handling means DEATH to your coin's integration to other Apps. stat... research how to do it. And, along with that...
  • 4.- A FRIGGEN INSTALLER: You want your average user to pick a folder to decompress your ".rar" (augh, .rar! c'mon)!? You're doomed pal... At least an NSIS or InnoSetup and Ubuntu PPA are the minimum requirement here for linux users... Mac, i dunno how is that, but make it easy and use the most standard use-case to install.
  • 5.- Proper download services: I know you all like MEGA, but most users are used to just click and the download starts. At most, there's a "Your download will begin soon" message after clicking on download. Don't use Google Drive (it throttles downloads), Mega, Dropbox, Skydrive.
  • 6.- DNS seeds: don't ever ever ever ever launch your coin without DNS seeds. If you use your coin with IRC seeds it will get tagged as virus by a lot of virus scan tools. A shitcoin asks to "addnode" on the .conf file.... plz, don't....
  • 7.- Github naming matters: i would have second toughts compiling and running a project located at github named "uranus-stinks/shitcoin". Plz, only use a name if you can register an account on github with the same name for the project as the name of the user. If any of both are taken, change your coin's name.
  • 8.- Socialize: I'm a nerd too... but your twitter account must be your most beloved and used possesion. Please, try to create an account with the exact same name of your coin before releasing your coin, if you do, people will find you easier. Coin updates must be twittered, posted on BTCtalk, etc.
  • 9.- Be tolerant: Bitcointalk has some great users, but there are an awful lot of trolls here. Tolerate them and treat them with respect. Brats are brats, don't be one.
  • 10.- Create and use DAILY a BTCTalk account for your coin: You can present your BTCTalk user on the OP, but for the sake of branding, your BTCTalk thread should be posted by a user with the exact same name as your coin. That user must log at least once a day, most users will begging FUDing if you don't log in after 2-3 days.

I have seen a good amount of coins die because of some fault like these. Print this, tattoo it to your hand, i dunno.... do whatever you can to keep your coin visible, fresh and your community alive.

EDIT:

New "muy-importante" point:

  • 11.- UPDATE YOUR OP TITLE WITH LATEST NEWS: Updating the OP lets watchers know what's happening to your coin with just a quick glance at "Show new replies to your posts" or "Watchlist" here on BTCTalk. Do it.
15  Alternate cryptocurrencies / Altcoin Discussion / [DEVELOPMENT] Extracting WIF and Address prefix codes from altcoins' sources on: June 14, 2014, 01:59:45 PM
I'm currently rolling my own wallet generator with the use of PYCoin https://github.com/richardkiss/pycoin and i'm having a hard time finding the WIF and Address prefix codes on the altcoins' sources.

BONUS QUESTION: The bip32 codes for each altcoin, where to find'em?

Does anyone know where to find it?

Simple non-dev explanation: Address prefix is for the special first character you see on most coins. WIF prefix is for importing the Wallet into the coins' client.

Some code:
Code:
###### excerpt from networks.py

NetworkValues = namedtuple('NetworkValues',
                           ('network_name', 'subnet_name', 'code', 'wif_prefix', 'address_prefix',
                            'pay_to_script_prefix', 'bip32_priv_prefix', 'bip32_pub_prefix'))

NetworkValues("Bitcoin", "mainnet", "BTC", b'\x80', b'\0', b'\5', h2b("0488ADE4"), h2b("0488B21E")),
NetworkValues("Dogecoin", "mainnet", "DOGE", b'\x9e', b'\x1e', b'\x16', h2b("02fda4e8"), h2b("02fda923")),

As you can see, BTC's wif prefix and address prefix are 0x80 and 0x05 each. DOGE's 0x93 and 0x1e.

I'm at a loss here.... halp plz
16  Alternate cryptocurrencies / Marketplace (Altcoins) / I'm going to sell some nice paper wallets on: May 10, 2014, 02:14:40 AM
I'm developing some nice paper wallets for MYR, SKC and GRS... I can include 3 more coins on the inital batch and want to know what good PoW coin out there can i support (no sense on including PoS coins, they need to be on hot wallet to stake).

They are cheap to produce here and will be donating 1/3 of the proceedings to each coin's foundation, payment will be on each coin's currency so no need to dump BTC on it (although parity will be like 0.006 BTC for 3-packs, 0.0045 on presale).

Features:

  • Scratch surface, like prypto (those prypto guys rock)
  • Hard paper... like business card but with better quality
  • Nice quality (premium feel, really, they'll rock)

Please, let me know what coins (should have working exchange rates)  can i include which have good exchange volumes.

17  Bitcoin / Project Development / SuperWallet - A No-BS CLI multiwallet with *some* exchanges data on: April 28, 2014, 04:51:01 AM
Hi, just uploaded my "Super Wallet"

https://github.com/chiguireitor/superwallet

I'm currently using it because managing multiple wallets from each of the GUIs of them is stupidly slow.
