Records of our activities can be kept on cloud servers, which can save anything from professional documents to personal data from our smartphones.
Our activities are made easier by this answer at first look, but hidden beneath the comfort and thorough customer service are some unexpected dangers.
Centralized data storage has increased speed, availability, and low latency, but all of these advantages come at a price.
Large cloud storage providers that dominate the market, like Google and Amazon, are frequently suspected of working with the government and allowing them access to sensitive information.
Users’ files are not encrypted, are kept in one location, and are open to alteration, making it simple to achieve.
For political reasons, governments may also impose access restrictions on particular pieces of content, as Turkish authorities did in 2017 when they forbade Wikipedia usage there.

China went much further, outlawing international social networking, cloud storage, and video platforms in favor of domestic alternatives. Contrary to centralized cloud storage, decentralized storage boast of being safer and more private.
They don’t keep user information on a solitary, central server. Instead, they split large files into smaller ones and distribute them to many servers or nodes, minimizing the chance of outside interference with user data. Despite these advances, decentralized storage nonetheless has significant limits.
Since blockchain technology began to take off, there have been proponents who assert that it will improve virtually every industry, including banking, voting, healthcare and fundraising.
Could that be the case with data storage? Can blockchain help the cloud storage market? Even though many alternatives have been put out, we are not yet making any firm judgments; only time will tell.
Blockchain-based decentralized cloud storage offers a number of appealing advantages over conventional centralized cloud services like Amazon or Google Drive.
Security
Blockchain-based decentralized cloud storage, which was covered in the part before this one, makes data transit and storage safer.
Private keys are used to encrypt files, making it nearly impossible for those without the key to access the file.
In order to prevent performance degradation, files are also split into parts and stored on several nodes. If a centralized server comes down, you’ll likely lose access to your data. Your files will be safe even if one node malfunctions.
Immutability
Since there is no centralized authority, no one can remove your file, control access to it, or alter it for censorship’s sake. The ledger stores the file’s hash.
Lower cost
While centralized cloud storage services like Google, Amazon S3 One, and Dropbox charge, respectively, $0.02, $0.023, and $0.005 per month for 1 GB of space, their blockchain-based rivals charge as little as $0.002.
Rewards for storing
Many decentralized storage initiatives leverage native currency and the blockchain to reward users. Hard drives, disks, and data centers with extra storage space can be rented out for a fee.
Platforms for blockchain-based cloud storage connect users who are prepared to share their storage space with those who are in need, creating a win-win situation.
