3  Bitcoin / Project Development / BIP32 Online Wallet Provider with API? on: August 17, 2016, 06:28:53 AM
I'm looking for a service like Blockchain.info's online wallet that supports BIP32 wallets, and has an outgoing payments API. If anyone has any suggestions, I'd appreciate it! I don't want to run BCI's server program on my server, which is the main reason I'm looking for an alternative.
4  Bitcoin / Project Development / Looking for HTTP callback service for receiving payments from xpub on: August 03, 2016, 05:54:24 PM
I'm looking for a payment receiving service that's similar to Blockchain.info's Receive Payments API (V2).  They refused to grant me an API key, but didn't provide a reason (because that's just how a $30M-funding company does business I guess), so I'm looking for a similar service that makes payments that easy to integrate.  Any suggestions?  Thanks!
5  Economy / Service Discussion / BrainWallet Defcon Attack Discussion, Advice, Q&A, Brainflayer Info, etc. on: August 09, 2015, 07:53:09 PM
In light of recent events, it has been proven that BrainWallet is now no longer regarded as safe.  At Defcon 23 (running August 6-9 2015), a whitehat hacker (named Ryan) released a program (codenamed Brainflayer) capable of checking 10s of thousands of brainwallets per second.  During his research, he discovered private keys for addresses that at some point held over 730BTC.  Many of the phrases were regarded as generally safe.  However, they were still cracked by his program.  BrainWallet as a whole is now being regarded as unsafe for use.  While experts have considered it unsafe for a long time, this is one of the first practical implementations that proves exactly how unsafe they are as a wallet choice.

Following the announcement and presentation of the software implementation, BrainWallet's website has been shut down.  The latest commit on their GitHub page removed the website and replaced it with a parked page, saying that the project is now closed.

However, there are still many safe BrainWallets.  As of now, it is recommended that you clean the balance out of your BrainWallet and into a safer storage method.  It is important to note that Ryan, the developer of this program, did not take any of the bitcoins.  He attempted to alert the owner of 250BTC that their bitcoins are at risk.  However, he has not personally gained anything from this, and works for the betterment of the bitcoin community.

While many BrainWallet cracking tools have existed over time, Brainfalyer is many orders of magnitude faster.  It uses Bloom Filters to effectively and quickly check if addresses have been used, which increases its speed.  Various other optimizations have made is very efficient as well.  In the next months, it can be expected that other hackers will be creating botnets, and various other large scale attacks against brain wallets.  It is no longer safe to use a BrainWallet.  Transfer funds out immediately!

The presentation regarding general information about the attack is available on Ryan's website.
The source code for the project is available on GitHub

If you are one of the lucky BrainWallet users who have not haven your bitcoins stolen, we have hosted the BrainWallet code on our website.  It can be used to transfer your bitcoins to a safer medium.  A Trezor or Electrum (cold storage) wallet is recommended for users with larger amounts of bitcoin.  They are easy to set up, and are many times safer than your BrainWallet.  To use the BrainWallet software, go to our website's hosting of BrainWallet.  For smaller amounts of bitcoin, you can use the website implementation itself.  For larger amounts, click the "Download ZIP" button in the footer of the website.  From there, you can generate the private key and transfer your bitcoins before theft occurs.

Please do not take this warning lightly.  Over 730BTC were available for theft thoughout the history of BrainWallet.  Please ensure that your bitcoins are not part of the ones that are taken in the future.  Save your bitcoins today, and transfer them to a safe storage system such as a Trezor or an Electrum Cold Storage wallet.
6  Bitcoin / Pools / BetaRigs Owner Tools Bot - A Monitoring and Updating Tool for Your Rigs on: August 08, 2015, 04:43:31 AM
Leasing out your rig on BetaRigs can get you an extra few percent profit above mining straight for a pool.  The only problem: you have to monitor and update your rig based on the relative price of other rigs.  We have designed a set of tools that alerts users when their rig goes down, and automatically updates the rig's price based on the current market price (+/- a user-defined percentage).

Our quick and easy interface, available on our website, makes it easy to enable our bot for your rig.

Currently, the project is not open source.  However, if we receive a few donations we would certainly consider releasing it as open source to allow others to set up the cron jobs on their own computer, and manage it yourself (just in case you don't trust us with your API key).  If you ever have any questions, we're here to help!  Donations are always accepted: 1MF7hKShzq2iSV9ZZ9hEx6ATnHQpFtM7cF!  Enjoy, and happy mining!

9  Bitcoin / Project Development / Bitcoin Agar on: June 27, 2015, 08:14:56 PM
Everyone loves agar.io, it's a fun and simple game.

I want to turn it into a bitcoin project.  If anyone has any ideas about how to go about this (theoretically), in terms of how to distribute the bitcoin, where the dots come from (which would represent a portion of bitcoin)?  What are people's thoughts?  I'm really interested in getting this going, as I think there's a huge opportunity here.

If anyone wants to help, PM me.  We can work on this together.
10  Bitcoin / Pools / Looking for Work/Ideas - Will Work for Free on: June 27, 2015, 07:57:57 PM
I'm looking for work, and I know there are a lot of pools that might need a little extra hand.  If anyone's interested in hiring (and I will work for pretty much free, let me know).

Also, if anyone has any great ideas for a new pool, pool features, etc., let me know!  I'd be interested in working on it.
11  Bitcoin / Project Development / 3D Printable Wallet Generator - A Paper Wallet Replacement on: June 24, 2015, 05:05:19 AM
When you think of paper's durability, what comes to mind?  Dogs eating homework made of it, paper dying in floods, getting crumbled, getting torn, getting worn - all horrible things that don't happen to plastic!

Until this point, there has been no easy way to generate a bitcoin (or other cryptocurrency) wallet that can be 3D printed (or milled with a CNC machine).

One week ago, we set out to fix this problem.  What we came up with can be viewed here: https://github.com/btcspry/3d-wallet-generator

Keep in mind, it is still a work in progress.  We are looking for developers to help critique our code in any way they wish.  We hope to have an awesome, easy-to-use product that bitcoin-savy people can use to generate their own wallets.

TL;DR - Now you can generate your own 3D-printable bitcoin and altcoin wallets here: https://github.com/btcspry/3d-wallet-generator

Update: We're now available on the PyPi package index, and can easily be installed by "pip".  See the install instructions in our readme in the GitHub repository!  Nearly anyone can now generate their own 3D-printable bitcoin wallets!
12  Bitcoin / Project Development / Single-Address Hardware Wallet on: June 22, 2015, 07:52:46 PM
Would anyone here buy a disposable hardware wallet that is programmed ONCE, and then cannot be programmed with a different private key.  Instead, you just toss it and buy a new one if you want a different address.  It would only have a single address, but I could still see this having some use.

It would only cost maybe $5 per wallet, so you could have 5 of them for pretty cheap, and then just get a new one if you need a new address (they wouldn't be HD, obviously).  It would be like the old paper wallets, but way easier and more secure to spend from.  Would anyone buy it?

The idea is that it would be really cheap and secure, and the address on it cannot be faked or anything.  Obviously it would be open source.  If anybody thinks it's a good idea, maybe we could start a development team (and a Kickstarter) eventually.  Lemme know what everyone thinks.
13  Bitcoin / Project Development / Crypto Lookup Chrome Extension - Web Store Release on: June 17, 2015, 04:29:01 AM
Everyone come check it out, it's pretty great!  Download the tool now: https://chrome.google.com/webstore/detail/crypto-lookup/inmhajodfjajjahndjoiebifcbokioim

Being a bitcoiner is tough.  You always want to check out address stats you see online (be it donation addresses, or anything else), but don't want to select the address, txid, etc., and copy it into your block explorer of choice.

We are here to fix this for you!  With this Google Chrome Extension installed, just right-click on the address, txid, or block hash, and click our button: we'll launch a block explorer in a new tab for you, with all your information.

We are looking for other developers to quickly review our code and let us know what y'all think (we're always looking for people to suggest/make improvements).

If there are any developers out there who are interested in joining the project more officially, let us know and we'll bring you aboard!

Check out the current project on GitHub here: https://github.com/btcspry/crypto-lookup

Don't forget to donate to 1MF7hKShzq2iSV9ZZ9hEx6ATnHQpFtM7cF (I dare you to use our extension to send to that address).

GitHub: https://github.com/btcspry/crypto-lookup

Update: Download the project right from the Chrome Extension web store: https://chrome.google.com/webstore/detail/crypto-lookup/inmhajodfjajjahndjoiebifcbokioim
