In recent years, cloud storage has emerged as the preferred option for more and more businesses owing to its flexibility, capacity, and easy data access. Moreover, reputed cloud storage providers such as Alibaba Cloud offer strong data encryption and other reliable provisions to ensure maximum security. Many companies have shifted their data centers onto the cloud due to high redundancy, load balancing, data integrity, and backup options.
One of the latest trends that are poised to gain momentum is to use Blockchain technology for cloud storage. There are many advantages of Blockchain-based cloud storage and in this blog, we will focus on some of them.
In Blockchain-based cloud storage, data is divided into multiple encrypted segments that are interlinked through a hashing function. These secured segments are distributed across the network and each segment resides on a decentralized location. There are strong security provisions like transaction ledgers, encryption through pubic/private key, and hashed blocks. It assures reliable and robust security against hackers. Even advanced hackers are unable to decrypt the data due to the sophisticated 256-bit encryption.
Let's look into an unlikely case of some hackers decrypting the data. Even in such scenario, each tedious decryption attempt leads to just a small segment of data being decrypted and not the entire file. The extreme security provisions not only discourage malicious hackers but also make hacking a useless pursuit from a commercial point of view due to extreme efforts required for trivial achievements (and very high probabilities of failures).
Another important thing to consider is that the owners' data is not stored on the node. It helps owners to retain their privacy. There are strong provisions for load balancing as well.
In the distributed cloud storage the users are connected in a secured P2P network that provides them a decentralized way to store their mission-critical data without compromising on the security. There are other powerful benefits of using Blockchain technology to store your data. It is up to 10 ten times faster and can lower the total expenses to half. Distributed cloud storage strategically combines transparency and security with the hash function, encryption through public/private key, and secured transaction ledgers.
The cloud-based decentralized storage also saves the clients from many security threats. Moreover, the access to encryption keys and un-encrypted files is restricted to the end-users only with the help of client-side encryption. All these factors offer the clients complete control over their diverse data assets.
One of the major concerns during cloud storage is ensuring that the original data has not been tampered with. The inherent verifiable architecture of Blockchain offers a trusted way to track the storage and backup history and confirm that the original data has not been tampered with. Instead of storing data, it stores only the encrypted hashes of related data blocks thus providing the footsteps of the data to verify its originality.
By sequentially linking the different blocks through cryptographic hashes the Blockchain automatically organizes the data in a verifiable order. As every single block is linked to the previous ones, it produces a decentralized, encrypted, and verifiable transaction ledger in a distributed form.
Blockchain provides complete transparency which simply means that any shady activity in the network can no longer remain in shadow. Moreover, its sequential storage ensures that each transaction can be verified at any time. By creating a strong, organized, and interconnected mesh of blocks the Blockchain-based cloud storage also facilitates immutable transaction records to verify ownership and identity.
Blockchain's distributed and hash encrypted ecosystem helps in building a trustworthy ecosystem and proactively protects against handling and fraud while reassuring that no compliances are breached by any member.
The use of smart contracts provides a strong technical provision to automatically enforce condition-based rewards and penalties. In short, it can be compared to self-sustainable machinery that can work automatically, independently, and accurately. Instead of residing on a central machine, the Blockchain is equally distributed across many systems that offer its immunity against major attacks.
Blockchain-based cloud storage perfectly combines security and scalability with its interlinked blocks, hashing functions, and decentralized architecture. It makes the technology an ideal choice for adding an extra layer of security to the cloud storage. By wisely incorporating Blockchain technology in cloud storage the businesses can reduce their IT expenditure, enhance the security, and streamline the flow of information.
