Adventures in Big Data: Bitcoin hacking: MongoDB infrastructure choice led to a hackeable system in finance

Bitcoin hacking: MongoDB infrastructure choice led to a hackeable system in finance

It's a dirty little secret that everyone knows: Bitcoin exchanges built on top of first-generation NoSQL infrastructure lack even the most basic measures to guarantee the integrity of their accounts.

A very interesting article on some Bitcoin exchanges that, based on NoSQL technologies (specifically MongoDB), have suffered from concurrency in their systems and have been (successfully) hacked.

What happened at Flexcoin, or Poloniex, or any of the other Bitcoin exchanges beset by technical problems (and I'm looking at you Coinbase!), was not an outlier or unexpected or unforeseable. The infrastructure is broken. And it is broken by design.

Flexicoin recently suffered a hacker attack that may well be shown to students on concurrency classes so they gain interest on how to make easy money due to exploiting other people's failures.

Bitcoin meets NoSQL: The story of Flexicoin and Poloniex

This article provides some ideas on fixing the problem, and also had the merit, in my case, to introduce HyperDex, a system I didn't know that provides consistency + scalability that they proactively evangelise.

I am working now for a firm specialized in finance, so I'm going to pay an extra attention to this kind of articles.

If you really need a professional hacker to hack your cheating boyfriend's/girlfriend's/spouse phone, whatsapp, facebook, bank account hack etc. Or credit score upgrade, I would recommend
ETHICALHACKERS009@GMAIL.COM
He has proven to be trustworthy, His jobs are fast and affordable. He has carried out over 3 jobs for me including helping me hack my ex wife's mobile phone and i can't forget when he cleared my credit card debts and improved my credit score to 750. I can put my money on him at anytime!. He's one of the best out there. Spreading the word as my little favor to him for all he's done. Thank me later.

I remember my experience with hackers i contacted online, i almost lost hope in finding out if my husband was loyal to me and has been loyal in our 20 years marriage, i lost a lot of funds in paying these so called hackers so i made up my mind that if i get scammed again i’ll just forget about finding out what God doesn’t want me to know, Then i saw reviews about (arstrongcyberwizard@yahoo.com ) and decided contact him and if and if i hear any stupid excuse won’t contact anybody and just accept that God doesn’t want me to then he proved to me that he isn’t a cheat by working a sample job for me but to my greatest surprise he did the job and sent results to me fast, i was so happy but sad part was i divorced my husband, and i will drop an advise for people who wants any kind of hacking services stopped being scammed by people who impersonate being hackers, contact ( later.arstrongcyberwizard@yahoo.com. ) for a fast and clean job. Thank me later. Whatsapp +8616608642225

I once had a credit score of 572, I pay my debts and other bills on time,I have a regular credit card and a secured credit card. Only had two collection that was not paid off and they were over 2 years old which had damage my score drastically and affected me in many ways. All efforts to raise my credit score quicker did not yield any result because it is rising slowly even with on time payments. Luckily I met a credit fixer who helped eliminate those collection on my report and raised my credit score to 784 through a friend. Don't really know how he got it done but I have recommend him to many of my friends and they benefited from his service. Mail him if you need a similar service at CLEVERHACKER.HACK@GMAIL.COM or phone (803)814-5462

Excellent and professional investigative services. I hired Mr. WHITE for a very private and difficult matter of hacking my husband's phone and he far exceeded my expectations. He helped me get some info such as WhatsApp, Facebook, text messages, call logs and even phone conversations that I needed for proof of his secretive affair. The first time we spoke, we had a very long phone consultation in which he gave me all my options that he could think of to resolve my case, and he even recommended I try other options before hiring him, which shows that he is honest. I decided to hire him and I am glad I did. He is a fantastic investigator and a great person; to all loyal partners out there if you have a dishonest partner don't hesitate to send him a mail Contact: WhitehatstechAtGmailDotCom
