How Blockchain Can Be Used To Secure Sensitive Data Storage

How Blockchain Can Be Used To Secure Sensitive Data Storage

How Blockchain Can be Used to Secure Sensitive Data Storage Click to learn more about author Mary Ann Callahan. Data Security is no longer a luxury or an afterthought. With so much of our private, personal, and sensitive information being stored and transmitted online, tight security and privacy are now necessities for everyone. But, just as more of our lives are going online, we are hearing about more data breaches and hacks than ever. Here were going to take a look at how Blockchain technology can improve on current, centralized data security solutions, and help keep us safe and in control. Data is quickly becoming one of the most valuable resources in the world. The list of the top 10 companies by market capitalization is now dominated by data-centric companies like Facebook, Alphabet, Microsoft, Apple, and Amazon. That value means your data, especially your sensitive data, is now a prime target for cyber criminals, and you probably arent as protected as you think. Even giant companies like Anthem , Target Corp, and Home Depot have had major data breaches over the last few years affecting hundreds of millions of people. Clearly, current solutions arent good enough to keep us safe. Cloud services often arent the solution either. As hugely centralized systems, they are more valuable targets still. You also need to trust a 3rd party to store your sensitive data for you, which for many companies often isnt desirable or even legal. A new solution is needed. Blockchain technology has been one of the major technological breakthroughs of this century. Bitcoin, the first Blockchain application, allows a network of users to perform transactions without requiring the trust of anyone on the network, or a third party. Everything is encrypted, and nobody can tamper with the Block Continue reading >>

Blockchain And Cryptocurrency May Soon Underpin Cloud Storage

Blockchain And Cryptocurrency May Soon Underpin Cloud Storage

Blockchain and cryptocurrency may soon underpin cloud storage Emerging now: P2P networks that use blockchain to manage cloud storage based on the sharing of excess drive and network capacity on PCs and in data centers. Those who share capacity get free storage and can be paid in cryptocurrency. Use commas to separate multiple email addresses How to fix a hard disk in Windows using the command prompt Through blockchain, Roberto Galoppini sees an opportunity to kill two birds with one stone: His organization, FileZilla, can offer users free online data storage while also allowing them to earn valuable cryptocurrency. Galoppini, director of strategy for FileZilla , the popular, open-source FTP client, said his service is planning to shift direction this year by using a peer-to-peer (P2P), distributed storage platform from Atlanta-based Storj Labs Inc. that will be managed via blockchain. [ Related: Blockchain in the real world: 3 enterprise use cases ] FileZilla, which has been piloting the Storj decentralized storage for several months,had been making money through its free file-sharing service, which is hosted on SourceForge.net. It pitches users third-party software or offers to let them make money by testing a new web or mobile application. In turn, FileZilla would share revenue with the third-party software vendors. Some users, however, reported adware was being installed without consent, and in general, the advertising isn't always popular with users, Galoppini said. By sharing revenue with Storj Labs, FileZilla would be able to continue offering users its free service and even expand feature sets using the native cryptography of blockchain, such as offering free access to a VPN. "People have been using FileZilla for free for so many years, it's important to find a Continue reading >>

How Can Blockchain Be Used As A Database To Store Data?

How Can Blockchain Be Used As A Database To Store Data?

How can blockchain be used as a database to store data? Currently decentralized blockchain applications have few options to store data. Decentralized storage options are: Decentralized cloud file storages, such as Storj, Sia, Ethereum Swarm, etc. Distributed Databases, such as Apache Cassandra, Rethink DB, etc. Storing everything in blockchain itself: Storing everything in blockchain is the simplest solution. Currently most of the simple decentralized applications work exactly this way. However, this approach has significant drawbacks. First of all transactions to blockchain are slow to confirm. It may seem to be fast for money transfer (anyone can wait a minute), but it is extremely slow for a rich application data flow. Rich application may require many thousands transactions per second. Secondly, it is immutable. The immutability is the strength of blockchain that gives it high robustness but it is a weakness for a data storage. User may change their profile or replace their photo, still all the previous data will sit in blockchain forever and can be seen by anyone. The immutability results in one more drawback - the capacity. If all the applications would keep their data in blockchain, the blockchain size will grow rapidly, exceeding publicly available hard drive capacity. Full nodes can require special hardware. It may result in dangerous centralization of blockchain. Thats why storing data in blockchain only is not a good option for a rich decentralized application. Peer to peer file system, such as InterPlanetary File System. IPFS allows to share files on client computers and unites them in the global file system. The technology is based on BitTorrent protocol and Distributed Hash Table. There are several good moments. It is really peer to peer - to share anythi Continue reading >>

Blockchain And Data Storage: The Future Is Decentralized

Blockchain And Data Storage: The Future Is Decentralized

Blockchain and Data Storage: The Future is Decentralized 2017 was the year when blockchain technology burst into the public consciousness. Even beyond the truly startling rise of cryptocurrencies, we became aware of how a range of markets could be transformed by applications built on the technology. But as with any emerging technology that suddenly gains fame and begins to be applied across real-world use cases, issues have emerged around the underlying characteristics of blockchain many of which should be a primary focus of the coming year. Chief among these concerns is scalability. That being said, the existence of these issues serves as a marker of just how far blockchain has come. Tech leaders now posit that it could underpin the next phase of the internet, creating the decentralized world wide web. As we look ahead to this new, decentralized internet, it is important to consider one of its most important elements: decentralized storage. While blockchain is on the rise, its hardly the only technology thats straining existing storage systems. Artificial Intelligence (AI), and particularly the Internet of Things (IoT), are also challenging the current boundaries of storage. Its estimated that there will be over 20 billion connected devices by 2020 , all of which will generate and then require management, storage, and retrieval of enormous amounts of data. Connected devices, combined with consumer personalization apps and the increasing need to share data across business lines, are all playing their part in increasing demand for storage. Businesses wanting to launch new, data-driven applications face a mountain of time, effort and coordination to provision new databases today. This drive towards a richer, more data-centric (and data-heavy) way of working is taking pla Continue reading >>

How Blockchain Will Disrupt Data Storage

How Blockchain Will Disrupt Data Storage

Among many other industries and sectors, Blockchain technology is poised to majorly disrupt data storage and cloud computing in the next few years. Instead of storing files and information on centralized servers such as Google Drive, Dropbox or Amazon S3, platforms like Sia or Storj use Blockchain technology to decentralize data storage by breaking up files into multiple pieces, encrypting and sending them to hard drives located all around the world. Individuals and private businesses can participate by renting out their unused hard drive space and make money. Sia and Storj have launched their own cryptocurrencies (Siacoin, Storjcoin) in order to incentivize usage and to create a market for buying and selling decentralized storage. So what are the main advantages of decentralized cloud service vs. private centralized cloud services offered by Amazon, IBM, Dropbox, etc.? More security & privacy. Decentralized data is also more difficult to attack than centralized data. On a decentralized network, files are broken apart and spread across multiple nodes (with sharding). The files are encrypted with a private key which makes it impossible for the node (participant in the network) to look at your file. Moreover, due to sharding, the files are just a fraction of their original self which render the reading of their content impossible. File loss prevention through redundancy in data (extra copies stored in case of error in storing or transmission of data). Cost reduction due to more efficiency. Blockchain storage costs can reduce the price of cloud computing between 50% -100%. (Storj VS Amazon S3 vs Microsoft Azure, via Storj Website) Increased speed due to servers proximity, scaling effects and fragmentation of data (smaller fragments can be saved and retrieved concurrently) Continue reading >>

Storing Data On Blockchain

Storing Data On Blockchain

I am working on a POC where I have to store some data e.g. ID of an object, price, owner and things like that. Is it possible to store such things on Blockchain using smart contracts. And if not what are the ways to use Blockchain to achieve it. (I did some research, and people are using Blockchain in SCM industry. They must have stored these kind of datas). Consider following tutorial from Hyperledger Fabric " Getting Started " pages. Basically you implement requested logic on by leveraging chaincodes , you will have to implement following golang interface: // Chaincode interface must be implemented by all chaincodes. The fabric runs// the transactions by calling these functions as specified.type Chaincode interface { // Init is called during Instantiate transaction after the chaincode container // has been established for the first time, allowing the chaincode to // initialize its internal data Init(stub ChaincodeStubInterface) pb.Response // Invoke is called to update or query the ledger in a proposal transaction. // Updated state variables are not committed to the ledger until the // transaction is committed. Invoke(stub ChaincodeStubInterface) pb.Response} type myStoreChaincode struct {}func (cc *myStoreChaincode) Init(stub ChaincodeStubInterface) pb.Response { return shim.Success(nil)}func (cc *myStoreChaincode) Invoke(stub ChaincodeStubInterface) pb.Response { action, params = stub.GetFunctionAndParameters() if action == "storeItem" { cc.StoreItem(stub, params) } // Handle here other cases and possible parameters combinations return shim.Success(nil)}func (cc *myStoreChaincode) StoreItem(stub ChaincodeStubInterface, params []string) { // Store item on ledger, where params[0] is a key and params[1] actual value stub.PutState(params[0], params[1])} This is only a Continue reading >>

Blockchain: Is It The Future Of Data Storage?

Blockchain: Is It The Future Of Data Storage?

Blockchain: Is it the future of data storage? Blockchain is the number-one trend worldwide. Still, there is a lack of understanding of this technology among regular people, as they are used to considering it from the perspective of cryptocurrency. However, the Blockchain concept goes well beyond the digital currency marketplace and bitcoin exchange . Most of us have heard key phrasessuch as: decentralisation, no third party, autonomous, peer-to-peer. Although, many people do not have a keen insight on how in fact everything actually works. Lets learn the ropes and figure out, whether blockchain is a far-reaching and ambitious concept or a hyped falsehood. Like the Internet, Blockchain technology deals with information, but it takes it to a whole new level. So, from now on, you have to understand that everything can be perceived as information, even money. (For example: Bitcoin, the first of its kind cryptocurrency , in terms of which blockchain was implemented for the first time, is no more than a piece of digital information that has a certain value that you own.) Now, lets try to piece things together and go through the key phrases again. Blockchain is: A technology, on the basis of which a certain network can be designed. This network differs markedly from any other networks we recently had, because... It is decentralized. (For example: any website is hosted on a server, that means it is centralized.) Blockchain network, on the contrary, is allocated among tens or hundreds of thousands devices worldwide that process the network. In this regard... It doesnt require a third party. When it comes to valuable information, a third-party service is, commonly, required to be the guarantor of the security of this information. Due to the fact that blockchain is allocated and Continue reading >>

Is Blockchain Technology Really The Answer To Decentralized Storage?

Is Blockchain Technology Really The Answer To Decentralized Storage?

Is Blockchain Technology Really the Answer to Decentralized Storage? Blockchain is extraordinary technology, but may not be appropriate for storing large files, other data. The Blockchain has become much more than a simple piece of technology. It has become a symbol for freedom, transparency and fairness. With this being said, its no wonder we see projects leveraging Blockchain tech as a one-size-fits-all tool to solve all sorts of problems, many of which could not be further from the original purpose of the Blockchain. Nowadays, the words Blockchain technology are thrown around alot and sometimes the use of the technology itself is unnecessary. Tim Swanson, Director of Market Research at R3CEV has even coined the term " chain washing "to describe companies/startups that are using or trying to use Blockchain technology in certain areas when in fact, they could be using more advanced technology for the purpose at hand. This becomes especially evident when it comes to file and data storage. Although the Bitcoin Blockchain is basically a decentralized database for transactions, accounts and balances, keeping that information on a decentralized ledger is already proving to be a challenge due to capacity issues. Nevertheless, several projects and companies insist on looking at Blockchain-based solutions for storage and, while there are clear cases of misguided enthusiasm when it comes to the use of Blockchain technology, there are some projects out there that are worth taking a look at. Blockchain Technology as an Incentive Layer When it comes to a mutualistic relation between Decentralized Ledger Technology (DLT) and data storage, the most common use case for the Blockchain is as an incentive layer. This means that data isnt stored on the Blockchain itself, but the network Continue reading >>

How To Use Blockchain To Build A Database Solution

How To Use Blockchain To Build A Database Solution

How to use blockchain to build a database solution Why would you want to use blockchain to build a database solution? And how would you actually do that? BigchainDB has answers. First Wall Street , then the database world. While most people are still trying to wrap their heads around blockchain and its difference from Bitcoin, others are using it in a wide range of domains. Is it hype, a case of having a hammer and seeing problems as nails, or could blockchain actually have a purpose in the database world? BigchainDB 's creators argue there is a reason, and a way, for blockchain and databases to live happily ever after. Blockchain technology, put simply, is a type of digital ledger which records transactions, agreements, contracts and sales. The technology is decentralized, which means that information is stored in computers around the world, and is constantly updated in real-time to reflect changes in stock, sales and accounts by bringing records together into blocks before algorithms 'chain' these data stores together chronologically. Blockchain was introduced by Bitcoin, which despite its oft discussed issues has illustrated a novel set of benefits: decentralized control, where "no one" owns or controls the network; immutability, where written data is "forever" tamper-resistant; and the ability to create and transfer assets on the network, without reliance on a central entity. The initial excitement surrounding Bitcoin stemmed from its use as a token of value, for example as an alternative to government-issued currencies. Now the separation between Bitcoin and the underlying blockchain technology is getting better understood, the scope of the technology itself and its applications are being extended. With this increase in scope, single monolithic blockchain technolo Continue reading >>

Forever Isnt Free: The Cost Of Storage On A Blockchain Database

Forever Isnt Free: The Cost Of Storage On A Blockchain Database

Internet Policy Intern at IPDB Foundation. Forever Isnt Free: The Cost of Storage on a Blockchain Database Cloud storage services work as follows: You pay a monthly fee up front for a fixed amount of storage space. During the paid time, you can use any amount of storage space up to that limit. When your paid time expires, you have two choices: pay for another month or your files get deleted. Your cloud provider only keeps your files for as long as you keep paying. Blockchain databases cant work on this model. A blockchain database must store data indefinitely, so the recurring payment model doesnt work. Data storage costs must be paid up front, and must cover not just that month but all the months and years to come. IPDB has developed a sustainable model for the long term storage of data: a one time, up-front payment that covers the cost of indefinite data storage. The payment must be enough to cover the cost of storage and the IPDB Foundations operating expenses. This blog post is a deep dive into the numbers that led to a single per-GB price point the cost of storing data indefinitely in a blockchain database. This kind of analysis has been lacking in the hype around blockchain technology. There are many problems that could be addressed with blockchain technology, but without an understanding of what a blockchain solution will cost, it is impossible to say whether economic efficiencies can be achieved. This post is a first step toward understanding which use cases could truly benefit from the application of blockchains. Before we dive into the model, lets outline some of our underlying assumptions: Conservative predictions: As a general rule, we have tried to keep estimates and assumptions very conservative. We would rather have happy surprises than unhappy surprises Continue reading >>

Storj - Decentralized Cloud Storage

Storj - Decentralized Cloud Storage

"Storj is like an Internet filesystem. Data blocks are encrypted and distributed across a globally distributed set of storage nodes using block-chain algorithm. It is quite impressive and much needed innovation in the storage space." "Decentralized file storage systems like Storj have the potential to eliminate high markup costs and market inefficiencies and provide a much higher level of privacy, reliability and quality of service than we see today." "The power of the Storj platform is its unique ability indiscriminately utilize the free capacity of a storage node, whether a single end-user PC or a massive data center. Storj is bringing an unprecedented degree of efficiency to globally distributed data storage." "Storj is a unique market phenomena. It sets new standards of unit economics for distributed data storage." "As a seed investor, we were more than happy to join the next round for Storj with a great line up of co-investors. We want storing files to be cheaper, faster and more secure and the progress the team has made towards that mission has been phenomenal to watch. We are looking forward to putting more and more of our documents on the Blockchain thanks to Storj." Continue reading >>

Blockchain And The Cloud: How Data Storage Could Change In The Coming Years

Blockchain And The Cloud: How Data Storage Could Change In The Coming Years

Blockchain And The Cloud: How Data Storage Could Change In The Coming Years February 28, 2018, 08:52:20 AM EDT By David Floyd Realizing what "the cloud" really means can be a letdown. Sure, sloughing all that data off was liberating. Companies no longer have to maintain their own finicky servers; individuals no longer have to devote so much cash to hardware or care to keeping everything backed up. The cloud untethers us from expensive circuitry and not a little stress. Except, as the line goes, there is no cloud. It's just someone else's computer. Rather than ascending to the heavens, vast quantities of individual and enterprise data were dumped into server farms run by the likes of Google, Amazon and Microsoft. These companies are good at running server farms, and the user experience is for the most part above reproach. (I'm writing in Google Docs right now.) But if you cringe at such deep, far-reaching centralizationif the Equifax breach makes you shudder at the headlines the coming years could bringthis situation won't do. Blockchain-based applications, which are trying to decentralize a range of digital services, are particularly reluctant to use Microsoft Azure or Amazon Web Services. That leaves local storage on user devices that are no longer designed for it. Unless, that is, we can decentralize storage the way bitcoin has decentralized financial transactions. A number of projects are working to make that happen. Their solutions employ various combinations of blockchain-based tokens, which storage renters use to compensate storage providers; smart contracts, which govern these transactions; encryption, which keeps the data secure; sharding, which keeps it manageable; and secure multiparty computation, which keeps it hidden even when it's being run through algori Continue reading >>

Storing (illegal) Data On Blockchain

Storing (illegal) Data On Blockchain

You may have seen in the news over the last couple days how researchers have found that the Bitcoin blockchain is being used to store illegal content, like images of child abuse or hacker code you can use to break encryption on DVDs. Using a blockchain to store files other than transactions is entirely possible; in fact some tokens deliberately exist to be an alternative file storage system (like Filecoin), despite the Bitcoin blockchain not being created for this. When you send money using your bank, there is often a little section for you to put a description of the transaction as long as it is just a few characters. There is a function called OP_RETURN that does the same thing with Bitcoin, which means that people can use it to post short messages. This is a deliberate function of the network. In fact, the first ever transaction has a message that reads "The Times 03/Jan/2009 Chancellor on brink of second bailout for banks". It is almost like a cryptic clue to blockchains mission statement. Storing much larger amounts of data was not part of the design however, and it most often involves fragmenting. This is where you have to make many transactions, each with a different piece of the data, before some clever software stitches it all together at the end. There is another way to store larger amounts of data where you essentially send your Bitcoin to a made up recipient (in Bitcoin language this means replacing the valid receiver keys with arbitrary data). This comes at a cost however, as there is no bank to ask for your money back. This is why it is called burning your Bitcoin. A 21 KB image of Nelson Mandela (which is already on the chain, by the way) would burn about $380 of Bitcoin at the current price of $8,400. While there are valuable uses for blockchain data st Continue reading >>

Blockchain Data Storage

Blockchain Data Storage

Blockchain technology will be used to create new, decentralized data storage networks, putting the power of choice back in the end-user's hands. One of the most heralded achievements of the internet era, both for personal and industry use, is cloud data storage. While this invention is quite recent it is already under threat of being upended by incoming blockchain storage technology competitors. One of the examples of this representative of near future blockchain use cases is how cloud storage companies try to avoid the loss of data. While big companies depend on spreading file duplicates throughout various data centers in order to avoid intrusion, decentralized blockchain technology would more or less eliminate the risk of meaningful disruptions. The decentralization of blockchain storage can have various additional financial benefits, such as potentially allowing the user to save on bandwidth since files are stored and downloaded from multiple nodes instead of from a single server. This is due to data being stored on dozens of individual nodes, intelligently distributed across the globe, with no central entity needing to control access to a users files, improving security and decreasing costs via decentralized file storage.While current network scalability still needs to evolve in order to accommodate large-scale file blockchain storage infrastructures, we can easily envision an industry where fragmented, encrypted data is supported by a network of decentralized nodes in a much more user-friendly and cost-effective way than the current, central database solutions. Another way blockchain use cases could revolutionize current file storage systems is by using what is known as an incentive layer. This means that while data is not actually stored on a decentralized ledger Continue reading >>
