How Blockchain Technology Comes To The Rescue
In an attack or an outrage will not have a devastating effect because the other nodes in other locations will continue functioning. Data is distributed across a network over the world. This cloud is shared and hence, this makes it impossible to tamper. It is encrypted in a manner in which only the owner can view the file. This makes records safe and decentralized. It allows the community to share the storage systems without letting anyone compromise other peoples sensitive data. Thus, blockchain and data are the two things that the world needs to address when it comes to data storage issues.
A blockchain-based storage solution is implemented by using two exciting technologies such as sharding and swarming. Let us now see how this works.
We first break the data into small chunks. These chunks are then encrypted and uploaded onto the blockchain. They have distributed in such a manner that these chunks are available even when a part of the network is down. This is referred to as redundancy. An adequate level of redundancy is ensured in the system.
The swarming technique lowers latency and increases performance as data is retrieved in parallel from nearest and convenient nodes. A swarm consists of numerous geographically distributed nodes and hence, accessing them through a decentralized network, leads to increased reliability and scalability. A single company does not own the swarms for storing data.
Its Not Necessarily More Secure
Finally, even the basic idea that distributed storage is more secure holds up only to a certain point.
Jumping off of the fact that data stored using a distributed method isnt easily usable, sacrificing usability for security falls through when you consider the fact that your data is only technically secure while its in storage.
If you want to edit your data, you have to reassemble and decrypt it, effectively unsecuring it for the time being. And if you want to share your data with a third party, you still have to send it their way, trusting that it wont get intercepted during transmission and that they, in turn, will store it safely.
The Benefits Of Using Blockchain For Cloud Storage
The benefits of using Blockchain for cloud storage are evident as the technology can provide a more secure and efficient way of handling data.
Blockchain offers a transparent, decentralized database that is tamper-proof and cannot be corrupted. This makes it an ideal solution for cloud storage, where security and trust are essential. In addition, by using Blockchain for cloud storage, businesses can save money on infrastructure costs.
The future of data storage is looking bright with the advent of Blockchain technology. With its many benefits, Blockchain is sure to play a huge role in the advancement of cloud computing. For businesses looking to store their data securely and efficiently, Blockchain is a clear choice.

Privacy Vs Auditing In Blockchains
The introduction of “private” or “anonymous” cryptocurrencies such as ZCash and Monero, highlighted the problem of blockchain auditing, with exchages and government entities limiting use of those currencies. Therefore, as the notions of privacy and auditing in blockchains are contradictory, auditing blockchains with privacy characteristics has become a research focus of the academic community.

How Is Information Stored And A High Level Of Protection Provided
Where is the blockchain stored? As already stated, the blockchain does not have one place to keep all the data. For the normal functioning of the technology, a whole network of computers is built, which are called nodes. The more such nodes, the more secure the system will be, but the longer the transaction will take.
Such computers can be stored in the same room or even rented from different users worldwide. It all depends on how complex the blockchain you need. Each such computer holds a full version of the blockchain, which is used as a backup. It is essential to understand that block chain storage should be as large as possible. The technology stores all data from the moment of its creation, so there must be enough space otherwise, the system will fail, the node will not perform the necessary actions.
It Is More Affordable Than Cloud Storage
One of the foremost benefits that are associated with the use of blockchain storage is that it is relatively cost-effective when compared to some centralized cloud storage platforms. For instance, common centralized cloud storage platforms like Amazon S3, Google One, and Dropbox offer 1 GB worth of storage space for the price of $0.023, $0.02, and $0.005 per month, respectively.
However, the prices for companies that offer secure storage services through blockchain storage go for as low as $0.002. This is a significant gap when compared to the amount charged by the centralized cloud storage platforms.
In another sense, the use of blockchain storage nullifies the payment of extra costs for third-parties and intermediaries that are involved in transaction processes of other payment systems outside of the blockchain system.

Potential Concerns For Blockchain
Since data has traditionally been stored on centralized databases, it has become more likely that any given hack will lead to a large amount of data exposure for a large number of users.
Despite the promises of blockchain to provide better security, its still important to consider some of the risks of blockchain implementation. Contrary to popular belief, the blockchain is indeed hackable. Sybil attacks, routing attacks, and DDoS attacks all present major security challenges for emerging blockchain projects.
For PoW consensus algorithm projects, 51% attacks executed by miners on blockchain networks have proven to cause big security issues for a number of projects. The Verge, and other projects, for example, have faced regular 51% attacks.
The fact that blockchain technology is still relatively new also means that the teams in charge of securing data have to consider a variety of possible security scenarios. They then must design sophisticated solutions to prevent data breaches from occurring. In several cases, projects have had to make reactive changes to their security measures instead of being more proactive in preventing threats.

What Is Blockchain In Cloud
Abstract: Blockchain technology is a distributed ledger with records of data containing all details of the transactions carried out and distributed among the nodes present in the network. All the transactions carried out in the system are confirmed by consensus mechanisms, and the data once stored cannot be altered.
So Where Does Blockchain Is Stored
The answer is not straightforward.
Blockchain is decentralized and hence there is no central place for it to be stored. Thats why it is stored in computers or systems all across the network. These systems or computers are known as nodes. Each of the nodes has one copy of the blockchain or in other words, the transactions that are done on the network.
So, you can think about the blockchain system similar to a spreadsheet where the values stored in each entry is the value of an address. Also, the spreadsheet is updated whenever a change happens.
Also, do you remember the Jim and Carry transaction example? If you do, then it is how the transaction is carried out, the data is generated, verified, and stored in the blockchain. Here, Jim and Carry both are termed as nodes. Jim uses his digital wallet to send the digital currency.
Also, the digital wallet is capable of connecting to the network and also has the list of other nodes and users. So, once Jim sends the transaction, it is transparent to the whole network.
It is broadcasted to the whole network that Jim has sent a certain amount to Carry. The broadcast is made until every other node knows about the transaction. Few nodes known as miners validate the transaction and once validation is done, the transaction becomes immutable and irreversible.
The whole process can take anywhere between a few minutes to a few hours depending on the network congestion.
Where And How Application Data Is Stored In Ethereum
Ethereum is used to build decentralized applications, a.k.a. DAPPs. These applications exist through small programs that live on the Blockchain, called smart contracts.
Before jumping into the platform and writing a smart contract, its really important to understand where your application data is stored. Code execution, servers and programming language are rarely critical to the design of an application. But data its structure and its security will constrain our design the most.
Lets imagine we are porting apps to Ethereum:
- For a Facebook-like, where are the publications and comments data?
- For a Dropbox-like, where are my private files?
- For a Slack-like chat app, where do we store discussion channels? And what about private messages?
Data Stores On The Blockchain
The blockchain technolodgy is based on a sequence of blocks, each of which carries a certain amount of information. This volume is limited to the blockchain framework. For example, for Bitcoin is 1 MB. The limit shows the maximum file size that can be uploaded to the Bitcoin blockchain. To store information about transactions 1 MB is enough, however, if you want to save an image or video file, you need to look for another solution.
A similar solution could theoretically become the Ethereum blockchain, since it has no restrictions on the block size. But in this case, another problem arises – the excessively high cost of storing information. The fact is that downloading data to the Ethereum blockchain is not free. It is spent on ethereum gas, which costs real money, and the larger the file size, the more this gas spends.
In 2017, it was estimated that downloading 1 KB of information on a blockchain costs users 2 US dollars. It turns out that loading a blockchain, for example, a 600 KB text file will cost users $ 1,200, a 5 GB movie is more than $ 10 million. The price is probably much lower now, as the market has sunk, but it’s still transcendental.

Where Is The Actual Data Stored In Blockchain
I know that the blockchain stores the transnational data and it is immutable but where is the actual data stored? If there is a use case to replace a centralized data center solution with a blockchain solution, where will the data be stored in blockchain? Data centers usually have petabytes of raw data, hence I am assuming that a decentralized solution like blockchain won’t be able to accommodate large amounts of data.
For e.g. bitcoin as of today is ~270GB, meaning that every node requires this much amount of storage. But the problem here is that the data is an ever increasing entity. How does blockchain try to solve this problem ?
Note: Many links on google say that blockchain is not an ideal solution for large data, but then any solution will eventually produce an ever increasing amount of data.
I have referenced the following question on the forum but it does not answer by doubts:Where is the data stored in Bitcoin?
where is the actual data stored?
Each full node on the network will download and validate the blockchain history, it will request and receive this data from other full node peers. Each node does not necessarily have to keep that data after validating it though, it can choose to ‘prune’ data that is not relevant to the user’s wallet.
For e.g. bitcoin as of today is ~270GB, meaning that every node requires this much amount of storage. But the problem here is that the data is an ever increasing entity.
Storing Transactional Data In A Blockchain
China company FileStorm, which describes itself in marketing materials as the first Interplanetary File Storage platform on blockchain, says the key to making it all work is to only store the transactional data in blockchain. The actual data files, such as large video files, are distributed in IPFS.
IPFS is a distributed, peer-to-peer file storage protocol. File parts come from multiple computers all at the same time, supposedly making the storage hardy. FileStorm adds blockchain on top of it for a form of transactional indexing.
Blockchain is designed to store transactions forever, and the data can never be altered, thus a trustworthy system is created, says Raymond Fu, founder of FileStorm and chief product officer of MOAC, the underlying blockchain system used, in a video on the FileStorm website.
The blocks are used to store only small transactional data, he says. You cant store the large files on it. Those are distributed. Decentralized data storage platforms are needed for added decentralized blockchain, he says.
YottaChain, another blockchain storage start-up project is coming at the whole thing from a slightly different angle. It claims its non-IPFS system is more secure partly because it performs deduplication after encryption.
Data is 10,000 times more secure than centralized storage, it says on its website. Deduplication eliminates duplicated or redundant data.

What Is Blockchain And How Does It Work
Blockchain is a digital ledger that records transactions in a secure, decentralized manner. It is often referred to as a distributed ledger or distributed ledger technology . Blockchain works by creating a shared database that is managed by a network of computers rather than a single central authority. This makes it resistant to tampering or modification and provides transparency and trust between parties.
How does blockchain work? Transactions are grouped into blocks and each block is chained to the previous block, creating a chronological record of all transactions. This chain is verified and stored across the network by all participating nodes . Nodes can be anyone from individuals to organizations. When someone wants to add a new transaction to the blockchain, they must first get approval from the majority of nodes in the network. This consensus-based system prevents bad actors from tampering with or corrupting the blockchain.
Blockchain is often associated with Bitcoin and other cryptocurrencies, but it has many potential uses beyond digital currencies. blockchain
how blockchain is improving cloud
Some of the key benefits of Blockchain include:
Security: As mentioned earlier, Blockchain is a secure and tamper-resistant way to store information. Because no single entity controls the data, it is much harder for hackers to gain access or make changes.
What Is The Blockchain
The blockchain can be described as a highly transparent, shared, distributed ledger that helps of transactions. All stakeholders on the network will interact with the network via a node in a transparent distributed ledger.
These nodes will hold a view or a subset of the shared ledger. Every transaction will have an identifying cryptographic signature, which will allow the secure transfer of data on a peer-to-peer network.

What Is The Alternative
While the blockchain is perfect for hosting smart contracts and cryptocurrencies, its not ideal for hosting large files, virtual machines, large databases, and more.
However, the story doesnt have to end here. At Artmotion, for example, we take a similar approach to secure business data. Our approach to military-grade encryption slices the data and distributes it across different locations in the data center.
As a result, in the event of a data breach, not only will any potentially stolen data be meaningless without a decryption key, hackers will also have to collect all the different slices and put them together in a meaningful way.
So while blockchain storage solutions have a lot of promise, its still not a revolutionary idea that can transform data storage.
