Tips, opinion and advice on data storage strategy Chrome OS: Why it may be time to approach desktop IT in a different way Inside the distros: A year in Linux development How to make the leap from traditional bank to digital bank Data storage has many fundamentals, but a key one is the idea that what we store should be or form part of a single, reliable copy. This is what is being strived for in concepts such as the file system , with its locking mechanisms to ensure the integrity of a file as it is worked on, for example.

We know this is not practically achieved more widely and that multiple versions of files proliferate across corporate storage systems, via emails, the internet etc. But, in some use cases it is absolutely essential that there is a single version of the truth, for financial transactions or in areas such as health records. There are also good economic reasons to want to keep single copies of data. Its simply cheaper 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 >>

How Does Data Storage On The Blockchain Work?

How Does Data Storage On The Blockchain Work?

How does data storage on the blockchain work? If I store file chunks in the blocks, I'm causing duplicated blocks all over the networks (I mean, my file's chunks will be in each computer on the blockchain network, So eventually I have many many copies of this file in each block of each computer). On the other hand, If I store reference to the file in the block(for example, the block will hold: Myfile.txt stores in IP: 123.123.123.123 and 11.11.11.11) each computer that has my file, can change it easily. and even If i'm checking whether 123.123.123.123 or 11.11.11.11 (my example above) changed my file, and the answer is "True" (by comparing file's hash before and after storage) , I still don't get my file, and the data storage on blockchain is pointless. So, how does companies like Storj works? how do they store the data on the blockchain? (As I understood, storj store references on the blocks, to 3 computers that holds my file, so how do they avoid my problem which I mentioned above?) Short answer is don't store chunks of files in the blockchain. It's not well-suited for this purpose. Better answer. It helps to consider separate concerns: Smart Contracts. Minimalist data that must be true for all users at all times. Focus is on fidelity, as it's extremely difficult to post false data into a contract that's careful about updates. Distributed Storage of large objects. Swarm, Storj and IPFS are examples of distributed object storage/distributed file system. They use various strategies for smearing out copies and shards across participating nodes, but they are not putting all things in all places at all times. At a very high level, we can consider a combination of these approaches. A distributed storage system can provide resilient storage of a blob, media, or JSON object Continue reading >>

Cooperative Storage Cloud

Cooperative Storage Cloud

A cooperative storage cloud is a decentralized model of networked online storage where data is stored on multiple computers ( nodes ), hosted by the participants cooperating in the cloud. For the cooperative scheme to be viable, the total storage contributed in aggregate must be at least equal to the amount of storage needed by end users. However, some nodes may contribute less storage and some may contribute more. There may be reward models to compensate the nodes contributing more. Unlike a traditional storage cloud , a cooperative does not directly employ dedicated servers for the actual storage of the data, thereby eliminating the need for a significant dedicated hardware investment. Each node in the cooperative runs specialized software which communicates with a centralized[ citation needed ] control and orchestration server, thereby allowing the node to both consume and contribute storage space to the cloud. The centralized control and orchestration server requires several orders of magnitude less resources (storage, computing power, and bandwidth) to operate, relative to the overall capacity of the cooperative. Files hosted in the cloud are fragmented and encrypted before leaving the local machine. They are then distributed randomly using a load balancing and geo-distribution algorithm to other nodes in the cooperative. Users can add an additional layer of security and reduce storage space by compressing and encrypting files before they are copied to the cloud. In order to maintain data integrity and high availability across a relatively unreliable set of computers over a wide area network like the Internet , the source node will add some level of redundancy to each data block . [1] This allows the system to recreate the entire block even if some nodes are tempo Continue reading >>

How Blockchain Tech Is Changing Cloud Storage

How Blockchain Tech Is Changing Cloud Storage

How Blockchain Tech Is Changing Cloud Storage Speed matters. End users want fast, seamless access to content. If your site is slow, they are just going to go to someone who can deliver. Just how quick do you need to be? A study from 2009 found that 47% of users expect a page to load in 2 seconds. If it didnt load in under 3 seconds, 40% were out of there. The study was released over eight years ago. Eight years! Thats two years after the original iPhone came out. Today, we expect a lot more, we expect things on-demand. Your customers wont wait around for your site to load. They are not going to sit patiently as your images load or video buffers. Almost instant access to a global marketplace means millions of options they could use instead. It isnt just users. Google uses site speed on both desktop and mobile sites as part of its SEO rankings. Thats why Content Distribution/Delivery Networks (CDNs) are becoming an integral part of smart business setup. More than just your website speed, user expectations are spread across the spectrum. We want faster transactions, easier access, more intuitive interfaces and guaranteed privacy. The Dropbox hack , recent iCloud scares , the NSA data tapping, and the Amazon Cloud failure earlier this year has led to growing concerns about the safety and availability of our data. Lets say you use a service like Google Drive for all your personal cloud storage needs. When you upload your data to the cloud, Google saves the data in one of their datacenters. When you want to access your data, your computer sends a request to that data centre and voila: youve got your data. But, the data centre isnt always close to your physical location (or your customers/visitors location). This usually means delivery delays, something most of us would prefe 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 >>

Filecoin V. Sia, Storj & Maidsafe: The Crowded Push For Decentralized Storage

Filecoin V. Sia, Storj & Maidsafe: The Crowded Push For Decentralized Storage

Filecoin v. Sia, Storj & MaidSafe: The Crowded Push for Decentralized Storage With exabytes of digital storage space left unused, according to its founder, Juan Benet, Filecoin is building an end-to-end encrypted decentralized storage network and file hosting platform. The company hopes those with large amounts of unused storage will rent their space in exchange for its tokens. Doing so would drive the price of storage down significantly, Benet said in an interview with Y Combinator in June. Its already pretty cheap. For its smallest enterprise customers, Amazon Web Services charges about $25 per terabyte. Benet says a secondary motivator will be that people need their data distributed across many providers and want stronger guarantees that their data will remain secure and wont be lost. Decentralized storage provides added data security, as files broken up and stored across multiple locations are more difficult to hack. In Filecoins markets, clients will spend tokens for storing and retrieving data while miners earn tokens by storing and serving data. Smart contracts will be deployed in the network to let users write their own conditions for storage as well as design reward strategies for miners, among other things. Filecoin eventually aims to integrate with other blockchains to bring storage and retrieval support to Zcash, Ethereum, and Bitcoin for example. Established competitors on the blockchain The blockchain is the future of cloud storage, say those in the industry already working in the space. Filecoin is entering a market where Storj, Sia and MaidSafe all have a working product available to the public. A fifth, Cryptyk, also under development, says it will achieve the security benefits of decentralized storage by spreading files across a handful of incumbent c 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 >>

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 >>

Blockchain Technology For Cloud Storage: This Looks Like The Future

Blockchain Technology For Cloud Storage: This Looks Like The Future

Blockchain technology for cloud storage: This looks like the future Theres been a lot of excitement over blockchain technology and its relation to finance, especially regarding bitcoin and other cryptocurrencies. Bitcoin's value skyrocketed in 2017, ending the year with a value of more than $14,000 after starting 2017 at just over $1,000. And its not the only cryptocurrency to see huge increases over the years. While some believe that cryptocurrencies are just another bubble waiting to burst, others see them as the future of finance. What happens if we consider blockchain technology for cloud storage? Thats just what many startups are beginning to do. The switch from centralized cloud computing As we know, storage infrastructure has transformed to generally being very centralized. Rather than businesses and corporations hosting their own servers, many have migrated to the cloud. This turn toward centralization lets companies push workloads to larger, public clouds in order to utilize the storage infrastructure of large companies, like Amazon Web Services or Microsoft Azure. Because of the centralization currently inherent in cloud computing, resources could be shared and the end customer could have much lower costs and higher efficiency and uptime. With this, cloud computing has massively grown, with Gartner claiming that the cloud shift will affect more than $1 trillion in IT spending by 2020. No one is doubting the benefits of cloud computing. However, data breaches or service interruptions arent unheard of, or even uncommon. Whether its user error or issues with the hosts themselves, data breaches in 2017 were a major story. For example, Verizon partnered with Nice Systems to handle customer service calls who utilized an unprotected Amazon S3 storage server. Because 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 >>

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 >>

Sia

Sia

Sia splits apart, encrypts, and distributes your files across a decentralized network. Since you hold the keys, you own your data. No outside company can access or control your files, unlike traditional cloud storage providers. Sia's decentralized cloud is on average 10x less expensive than current cloud storage providers. Storing 1TB on Sia costs about $2 per month, compared with $23 on Amazon S3. Calculate your savings below! Sia stores tiny pieces of your files on dozens of nodes across the globe. This eliminates any single point of failure and ensures highest possible uptime, on par with other cloud storage providers. Sia is completely open source. Over a dozen individuals have contributed to Sia's software, and there is an active community building innovative applications on top of the Sia API. Using the Sia blockchain, Sia creates a decentralized storage marketplace in which hosts compete for your business this leads to the lowest possible prices. Renters pay using Siacoin, which can also be mined and traded. Continue reading >>

Blockcloud: Re-inventing Cloud With Blockchains

Blockcloud: Re-inventing Cloud With Blockchains

BlockCloud: Re-inventing Cloud with Blockchains It's the year 2025 and it has been a stunning week in the world of computing. Larry Parallelogram, CEO of Avogadro Corporation, the worlds largest computing company, recently announced that 500 of the Fortune 500 have completed the migration of all mission critical processes to Avogadros compute platform, BlockCloud. This announcement, coming exactly one year after the bankruptcy of former computing giants IBM and HP, has reinforced the dominance of Avogadro in the Enterprise compute market. When asked to reflect on the success of BlockCloud, Parallelogram stated It can all be traced back to a day in 2017 when I met this Estonian company. Over the last ten years two of the most important technologies that have seen widespread adoption have been virtualization and Bitcoin. Virtualization paved the way for cloud computing and the Bitcoin protocol has the potential to reinvent finance using cryptographic building blocks called blockchains. Strangely, no one has put the two (Cloud and blockchains) together. If they did they would realize that together they would the solve the thorniest problem for Enterprise CIOs, namely: How do I comply with the law and trust my mission critical processes to an outsourced vendor who has little if any accountability? Bitcoin relies heavily on the blockchain, a public ledger of every transaction that has ever taken place that is distributed to the edge of the network. The key idea is that there is no centralized authority that is responsible for saying what is true or what is false, rather multiple distributed parties come to consensus, that consensus is entered into the ledger which thereafter can be accessed by anyone in the future. It is computationally infeasible for a single actor (or any Continue reading >>
