    Keywords/phrases: What should NOT go on a blockchain? 80% of what people are saying should be implemented on "blockchain." Right now, "blockchain" is a hammer and everything that looks like a nail is getting hit, which is mostly breaking things and not producing anything useful. Nobody really knows what a blockchain is, and it's being defined in such a ridiculously broad way. "Blockchain" is ultimately a meaningless word. Trust, transparency, and immutability are not properties of the blockchain; they are properties of a system that combines a blockchain, an open consensus mechanism with a proof-of-work investment in extrinsic energy, and a native asset that creates a game-theoretical reward system. They all work in conjunction to massively increase the decentralisation of the system until...

An individual claiming to be behind the recent Bitfinex (BFX) hack has announced the giveaway of 1,000 bitcoins, prompting those within the online community that this could be a money laundering scheme. Earlier this week, the Hong Kong-based bitcoin exchange revealed that it had suffered a major security breach after 119,756 bitcoins, amounting to around $65 million, had been stolen forcing a shutdown of its website and trading. The Reddit user, who goes by the name rekcahxfb, which spells bfxhacker backward, made the recent statement in a post that ‘one lucky winner will receive 1,000 BTC after one week from now,’ after asking people to submit their bitcoin addresses.

You can buy a bitcoin in the open market or ‘mine’ a bitcoin. Bitcoin mining is the process by which transactions are verified and added to the public ledger, known as the block chain, and also the means through which new bitcoins are released. On localbitcoins, the value of bitcoins can be found also be found out in rupees. Bitcoins are popular among hackers as they are just lines of code. They're digitally signed from one owner to the next and are largely anonymous.

DA INTERWEBZ — Volatile cryptocurrency markets have experienced massive gains in recent months, followed by huge dips and then subsequent signs of recovery. You may have heard of cryptocurrencies like Bitcoin and Ether or of the blockchain technology that underpins them. But what exactly is a blockchain? A blockchain is a digital database managed by a decentralized network of computers. The blockchain records transactions chronologically and publically, according to online blockchain resource, Blockgeeks.com. Distributing data through a peer-to-peer network hosted by millions of computers makes it far less vulnerable to hackers than a centralized network and protects files from getting lost. When a user requests a transaction on the blockchain, it is broadcast to the peer-to-peer network of computers, known as nodes. The nodes validate the transaction then combine it with other transactions to create a new block of data for the digital database. That block, which is both permanent and unalterable, is then added to the existing blockchain and the transaction is completed. Probably the most well known type of blockchain transaction involves cryptocurrencies such as Bitcoin or Ethereum, which has a value token called Ether. More than 900 cryptocurrencies are currently traded on the internet and the market is notoriously volatile. Blockchain technology can also be used record transactions for digital information such as contracts, or records like land rights and medical files. It may also have a huge impact on the Internet of Things. According to CNBC, recent drops in the cryptocurrency markets have been driven by profit-taking after Ethereum's exponential surge, uncertainty about a potential split in Bitcoin on Aug. 1 and startups selling large amounts of Ethereum after raising millions in U.S. dollars of the digital currency. ----------------------------------------­--------------------- Go to https://www.patreon.com/tomonews and become a Patron now TomoNews is now on Patreon and we've got some cool perks for our hardcore fans.

Imagine a bank that, by design, made everyone's password hashes and balances public. No two-factor authentication, no backsies on transfers. Welcome to "brainwallets", a way for truly paranoid cryptocurrency users to wager their fortunes on their ability to choose a good password or passphrase. Over the last decade, we've seen the same story play out dozens of times - a website is broken into, the user database is posted online, and most of the password hashes are cracked. Computers are now able make millions, billions or even trillions of guesses per second. Every eight character password you can type on a standard keyboard and every combination of five common english words could be tried in less than a day by today's botnets. Can people come up with passphrases able to stand up to that when money is on the line? Let's find out. For this talk, I will be releasing my high speed brainwallet cracker, "Brainflayer". I'll cover a history of brainwallets, safer passphrase-based wallet generation, passphrase security, in-the-wild cracking activity, and how I accidently stole 250 Bitcoins (and tracked down the owner to give them back). Ryan Castellucci has been interested in cryptography since childhood when his parents gave him a copy of "Codes, Ciphers and Secret Writing". He soon learned to program and wrote a tool to crack simple substitution ciphers. More recently, he co-spoke with Dan Kaminsky at DEF CON 22 and was a finalist in the 2014 Underhanded Crypto Contest. For his day job at White Ops, he finds new and exciting ways to tease out the subtle differences between bots and human-controlled web browsers.

Ever since the WannaCry attack, even people without any programming experience have been hearing about bitcoin. Hackers demanded payments from their victims in the form of this digital and anonymous currency in order for them to take back control of their hijacked computers. This “digital money” is made possible by the encryption technology blockchain. This technology isn’t just interesting for hackers – but also for Siemens engineers. We explain briefly what it’s all about.

http://bit.ly/1AJOQiZ Ever wondered what it would be like if you couldn’t prove your home, or even the land it’s built on, was actually yours? Ever pondered what happens to your data when you share it online, with your bank or with your government? At Bank to the future we believe that important records and data should be in your control, secure from hackers and stored in a way it cannot be tampered with. Well, you’ll be glad to know that these problems will soon become history. Factom developed technology to tackle these issues and chose to raise part of their funding on our Online Investment Platform - BankToTheFuture.com Unlike many companies, Factom believes that data should never be stored with one organisation. It is simply too attractive a target for hackers. Unlike banks, Factom believes that customers should only share their important information as and when it is needed. Unlike governments, Factom believes that important records should be stored in a tamper proof way, transparently and impossible to be altered. ...and we agree. BnkToTheFuture.com is the largest Online Investment Platform with thousands of professional investors waiting to invest in Financial and Technological innovation. Go to our homepage and you’ll get to see the total number of professional investors, how much they have invested, and the amount of dividends that they’ve received. Factom was a perfect match for us. They had built technology that stored huge data on the Bitcoin Blockchain secure from hackers, scalable and in a way that can never be tampered. They had already funded the development of the not-for-profit side of their technology by issuing their own CryptoCurrency, but were now ready to fund the for-profit side of their business. They secured a partnership with MicroSoft, a contract to build smart Cities in China and an initial agreement to build a proof-of-concept product to store land title deeds for a government. They wanted funding from professional investors who believed in them and knew the value of their business. and they wanted the investment to come through fast, in different currencies and with a streamlined compliance and documentation process. A solution was found, and Factom decided to list on Bank To The Future. We gave Factom access to a global community of thousands of qualifying investors ready to invest in Financial and Technological innovation. We gave them a platform that complies with international financial regulations tailored for most major currencies and countries. We structured the investment in a way that meant they only get one registered investor. We cut out the painful admin, legal costs and problems raising further finance in the future, as compliance and documentation was completed by us in an optimised investment structure. And all under a “no win, no fee” agreement with no up-front costs. We provided all our investors with one investment agreement and a forum to communicate with the team quickly, efficiently and privately with additional investor protections. Investors can download all legal work, due diligence and certificates via our platform whenever they want. We also invested in Factom through one of our Venture Capital funds - Bitcoin Capital, meaning, investors got to co-invest with us on the same terms and our interests are aligned. If Factom floats on a stock market, is acquired in the future or pays investors dividends, investors get their returns minus our 5% fee. We built our Online Investment Platform with one purpose in mind - to prepare for a radically different future in Financial and Technological Innovation... Businesses just like Factom can raise finance in a safe, fast and effective way, while our investors get to allocate a portion of their wealth to an extremely disruptive and fast growing area that many are beginning to see could change the world of finance - FOREVER! Just like Factom, you can get involved by making a quick online application for finance at BankToTheFuture.com or register to see if you qualify to invest. http://bit.ly/1AJOQiZ

Keywords/phrases: What should NOT go on a blockchain? 80% of what people are saying should be implemented on "blockchain." Right now, "blockchain" is a hammer and everything that looks like a nail is getting hit, which is mostly breaking things and not producing anything useful. Nobody really knows what a blockchain is, and it's being defined in such a ridiculously broad way. "Blockchain" is ultimately a meaningless word. Trust, transparency, and immutability are not properties of the blockchain; they are properties of a system that combines a blockchain, an open consensus mechanism with a proof-of-work investment in extrinsic energy, and a native asset that creates a game-theoretical reward system. They all work in conjunction to massively increase the decentralisation of the system until its decentralisation range is so high that immutability, security, transparency, and openness emerge as characteristics. You can't just say "let's do all of that without the decentralisation." If you are currently involved in a large proof-of-concept project where some consultant is selling you the abstract noun "blockchain," and they're telling you that the system you have now can be replaced with all these magical characteristics, take the word "blockchain" from the proposal and replace it with "Microsoft Sequel Server, Data Center Edition." If the proposal still works from an IT perspective, buy that instead. If you're using "blockchain" to mean "database," plus some hashes and signatures, you are missing the point. The magic of this technology is the decentralisation, and to remove that is to remove the magic; that is the measure for success from which all the interesting characteristics emerge from.

The concept of a Smart contract has been around for 20 years. Many of the ideas were first described by Nick Szabó in his paper, Formalising and Securing Relationships on Public Networks. Today we can put the theory into practice with real life Smart Contracts thanks to projects like Eris and Ethereum, just two of the latest tech companies who have developed platforms and protocols which integrate legal contracts with code. The event will include basics of the block chain technology applied to other than financial transactions and an open discussion.

Looks like the Bitfinex hacker is looking to make somebody rich? An individual claiming to be behind the recent Bitfinex (BFX) hack has announced the giveaway of 1,000 bitcoins, prompting those within the online community that this could be a money laundering scheme. Earlier this week, the Hong Kong-based bitcoin exchange revealed that it had suffered a major security breach after 119,756 bitcoins, amounting to around $65 million, had been stolen forcing a shutdown of its website and trading. The Reddit user, who goes by the name rekcahxfb, which spells bfxhacker backward, made the recent statement in a post that ‘one lucky winner will receive 1,000 BTC after one week from now,’ after asking people to submit their bitcoin addresses.

(17:45) Track List created with http://www.vinjavideo.com. --- --- Erasing anonymity: How to prevent hacking with blockchain | #ibmwow by Brittany Greaner | Oct 25, 2016 The recent distributed denial of service attacks has everyone talking. The responsible party managed to take down more than 80 sites, including Twitter, Spotify and Amazon. But IBM Corp. has a technology that is working to prevent hacks like that from happening, and also making it easy to trace were someone to try. Part of the problem with the recent attacks is that the networks had many anonymous users, making it difficult to trace who had done what from where. “You need one [network] that’s private and you know everyone on the network, so if any unknown entity accesses it, you can isolate it immediately,” said Shyam Nagarajan, director of Global Sales, Blockchain and Smarter Process at IBM. Nagarajan was interviewed by Dave Vellante (@dvellante) and John Furrier (@furrier), hosts of theCUBE*, from the SiliconANGLE Media team, during IBM World of Watson 2016 in Las Vegas, NV. The threat of anonymity is eliminated with blockchain, a technology that serves as the public ledger for financial transactions. To hack such a system, 51 percent or more of the users would have to be in on the hack – an unthinkable percentage, according to Nagarajan. In addition, significant amounts of assets are not moved on the network itself, meaning that even if there were an attack, the hackers would be unlikely to get much out of it. Tools and tips for customers IBM has three messages it would like to get out to customers. The first is that it’s invested in bringing in a community around Hyperledger, blockchain technologies for business. The second message is that IBM offers blockchain to both developers and organizations that are just getting started. This includes tutorials and walkthroughs, included through IBM Bluemix cloud platform. The third and final message: “We are actively working with customers and building solutions together. … Every conversation with the customer is a little bit different because their needs are different,” said Nagarajan.

Walmart, a $ 214 billion retail giant, began using block chain technology to identify recalled foods and remove it from the list of products. IBM and Wal-Mart have been working since October when Bridget van Kralingen, senior vice president of IBM Food touches us everywhere, so we experiment in China with Walmart and Tsinghua, given the size and the extent of food consumption in this country. Infrastructure Walmart Currently, Walmart, depends on an IT infrastructure that the company's days to research its database and discover the origin of a product. When a customer a formal complaint letter regarding topics to a particular product or Walmart bad food, the Walmart computer service alarmed. When filing the complaint letter different databases and servers are analyzed to identify the origin, suppliers, transmission time, among other crucial details that are relevant can be found to the situation. With a block-based system in place, however, Walmart executives are that consumers and businesses will be able to access to check its registry in real-time and identify any information about that product. More importantly, because Block Chain technology is decentralized, it protects the network from the blockade Walmart chain targeted by hackers or manage data changes. Walmart-based Arkansas Frank Yiannas, vice president of food security in Bentonville, with the Block chain, you make strategic moves, and that consumers and businesses trust. We believe that improved traceability is good for other aspects of food systems. We hope that you can count on other important attributes that should inform decisions circulate around the food, and even absorb effectively. Partnership with IBM Although Walmart still not fully disclosed to the technical aspects of its network Block chain, explained that Walmart used systems-based Yiannas Bloc and IBM networks to develop its own unique platform. Since the end of 2016, IBM began the quality business offer Block chain services for businesses. Bloomberg notes that if Walmart decides to block IBM's fixed network chain and commercially deploy large-scale, it will most likely be expanded by now the largest Block implementation of the chain.

Bitcoin is a digital currency with no central bank that issues these ‘coins’. Through a public ledger it can be identified who currently owns a bitcoin. You can buy a bitcoin in the open market or ‘mine’ a bitcoin. Bitcoin mining is the process by which transactions are verified and added to the public ledger, known as the block chain, and also the means through which new bitcoins are released. On localbitcoins, the value of bitcoins can be found also be found out in rupees. Bitcoins are popular among hackers as they are just lines of code. They're digitally signed from one owner to the next and are largely anonymous. Bitcoins are much harder to trace as compared to regular transactions as it cannot be directly identified who owns the bitcoin wallet. Cyber experts and researchers are currently tracing certain wallets linked to the recent attacks and law enforcement agencies are getting better day by day at tracking the movement of Bitcoins across the world.
