Decentralized Data Storage and Enhanced Privacy and Security with Blockchain

I’m a researcher and creator concerned about new applied sciences that give a contribution to the social excellent.

Everyone has spotted tales within the media of huge knowledge breaches that compromise the privateness and safety of people. For instance, Marriott Hotel’s contemporary breach or the notorious fappening/celebgate that noticed celebrities like Jennifer Lawrence have their iClouds hacked. These occasions mirror the inherent vulnerability of centralized knowledge garage to virtual assault and robbery. 

The reason why is simple to seize: the entire knowledge is saved in one position. Mainstream mass knowledge garage answers typically retailer every knowledge object on one or two servers. This makes the information susceptible to hackers who may just get the entire content material by way of attacking handiest the ones one or two servers.

In distinction, blockchain era makes decentralized knowledge garage conceivable by way of spreading knowledge throughout a big community of nodes, so it isn’t conceivable to thieve it by way of attacking handiest one or two servers. One must Mod a complete community of nodes. The impracticality of this makes blockchain knowledge garage a lot more protected than present choices.


Blockchain’s garage and safety functions make it a possible choice to centralized and cloud-based garage. A key mechanism to try this is named “sharding”, because of this splitting one thing up into fragments. For instance, knowledge (paperwork, contracts, studies, and so on.) saved at the Sharder Network is encrypted and “sharded”, i.e. cut up into a couple of small fragments. It is then allotted to other storer nodes around the globe. In distinction, present cloud garage answers typically retailer knowledge on one or two servers with out sharding or encryption.

Verification and Authentication

In addition to knowledge garage, blockchain additionally has the capability to validate knowledge and come across whether or not it’s been altered. Blockchain era makes it conceivable to make sure the authenticity of a document the usage of its virtual fingerprint or hash. Through this marker, the information’s proprietor too can stay entire possession and get admission to to the guidelines whilst no one with out authorization can get admission to it. 

Use Case: Legal Contracts and Personal Privacy

SignEase is an application for signing contracts and validating recordsdata that makes use of the Sharder chain for garage. It uploads signed contracts and validated recordsdata with a transaction ID that shall we customers hint and check the saved contracts and recordsdata. The verification and authentication capacities of blockchain era imply that each one e-contracts and recordsdata saved and validated on SignEase are legally legitimate.

ISLAND is a telephone application constructed on Sharder Network, launching in October 2020. Its serve as is to offer protection to folks maximum delicate knowledge. It can give protection to other people from incidents just like the fappening the place iClouds have been hacked. It additionally acts as a hidden picture app, so other people can retailer delicate pictures and movies that they are not looking for saved of their telephones gallery

Credit-Based Proof of Stake 

The consensus mechanism utilized by the Sharder Network to protected the community is referred to as Credit founded Proof of Stake (CPoS). CPoS consensus consensus has some great benefits of each PoS (Proof of Stake) and PoC (Proof of Credit). Based at the CPoS consensus, the Block era rights within the Network are made up our minds by way of a node’s PoC rating and the quantity of Sharder token (SS) held. This ends up in smaller collection of nodes making it conceivable to create upper potency and extra transactions according to 2d, in addition to a decrease likelihood of block mistakes and rollbacks. This isn’t the Bitcoin style of attracting nodes (miners) to sign up for the community by way of rewarding only on mining. Most of the nodes will probably be rewarded for offering garage, validation, authentication and garage functions.


Though Sharder itself is one garage community, it’s obtainable to different public blockchains similar to Qtum, Ethereum, garage networks similar to IPFS, Aliyun, Baidu Cloud, and private garage gadgets similar to onerous disks and cloud disks. The talent to finish cross-chain uploads to a couple of blockchains allows different chains to make use of Sharder’s garage and validation capacity. This means makes cross-chain knowledge verification conceivable reduces the desire for different chains to construct their very own garage and validation purposes.

Plug and Play Blockchain Services

Like others within the rising blockchain area, Sharder plans to make use of the Blockchain as a Service (BaaS) style to export its validation and garage functions externally. Customers who wish to use blockchain garage and validation won’t want to set up any particular device shopper. They can use the Blockchain as a Service API immediately to serve their particular trade want. They can retailer and validate paperwork, contracts and studies using blockchain era to verify all virtual recordsdata are securely saved, immutable and traceable.


Blockchain’s capacities to safely retailer knowledge, in addition to check its authenticity and make sure it may well’t be altered opens up virtually unending trade alternatives in all sorts of industries starting from aerospace, training, executive, regulation, medication and actual property. Companies are racing to benefit from them.
