What Is Decentralized Storage? Final Information

Decentralized storage is a system of storing knowledge on a number of decentralized clouds and servers as a substitute of a single centralized location. Not like centralized fashions, the place knowledge storage is concentrated within the arms of some tech giants, decentralized storage is a peer-to-peer (P2P) cloud storage answer the place bizarre customers handle the system. Customers lease out free disk area on their drives and are incentivized with tokens in return for his or her contribution.

For so long as one can bear in mind, centralized cloud storage suppliers (CSPs) like Google, Microsoft, Apple, and Amazon have been enterprises’ most popular alternative for storing knowledge. Whereas these CSPs present quite a few advantages, they’ve been accused of monopolizing the market and pigeonholing prospects into inflexible storage plans. Moreover, they’re inclined to cyberattacks that may cripple techniques and trigger disastrous monetary loss.

“As we noticed within the Equifax and Experian breaches and the current TransUnion drawback with a felony getting access to the info, these centralized knowledge shops are treasure troves for criminals and appeal to assaults accordingly,” says Uri Arad, co-founder and VP of product and analysis at Identiq. “That, in flip, is disastrous for shopper privateness and makes efficient cybersecurity and fraud safety far harder.”

Given the failings in centralized options, it could be time to discover different knowledge storage choices like decentralized knowledge storage.    

How decentralized storage works

CSPs retailer knowledge in servers unfold throughout a number of geographic areas they personal and handle. Because of this, in addition they wield huge energy over person knowledge. In distinction, decentralized storage has a extremely democratic method to knowledge administration. Right here anybody can take part and earn bitcoins by renting out their disk area.

Decentralized storage breaks the info into small items by way of a course of referred to as sharding after which shops them in a number of computer systems referred to as nodes owned by individuals such as you and me. As soon as break up, every file/knowledge is supplied a singular figuring out quantity, encrypted with a personal key, and distributed to unbiased nodes worldwide.

To keep up redundancy, a number of copies of the info are created in order that even when one node fails, the info can nonetheless be retrieved from different nodes. As there’s no single server, there’s no query of knowledge being broken or unavailable. Within the case of decentralized techniques, the info is saved in lots of and presumably 1000’s of nodes worldwide, so you’re all the time assured excessive knowledge availability.

For the reason that knowledge is encrypted, nodes can’t see or change your information; for security causes, solely customers with the identical set of encryption keys are in a position to entry the info. This makes it extremely safe. Likewise, since all information are distributed, even when attackers attempt to hack into nodes, they get solely encrypted chunks of knowledge, not the whole knowledge, which in the end serves them no goal. It’s exactly this function of decentralized storage that makes it extremely safe.  

The advantages of decentralized storage 

Decentralized storage comes with quite a lot of advantages, together with decreasing prices whereas elevating safety, reliability, scalability, and knowledge privateness.

Decrease prices

A decentralized storage mannequin doesn’t require important funding in knowledge facilities, making it cheaper than centralized storage options. Additional, there’s a strong market of customers prepared to lease their unused disk area, which lowers the prices much more. 

Larger safety

In decentralized storage, information are damaged down and unfold throughout a number of nodes. This ensures that, even when one node is hacked, the remaining should not affected. Having trustless structure, granular entry controls, and no single level of failure are further options that improve safety.

Greater reliability

Decentralized clouds have much less downtime as a result of knowledge is distributed throughout unrelated nodes. So even when a specific server goes down, you’ll be able to retrieve your knowledge from different nodes.

Extremely scalable

Decentralized nodes will be scaled up at will, making them extremely scalable in comparison with CSPs.

Higher privateness

For the reason that knowledge is encrypted, your private info is all the time secure.

The drawbacks of decentralized storage 

Whereas the idea of decentralized storage is certainly promising, it does have sure drawbacks that can’t be ignored. 


By far, some of the important drawbacks of decentralized cloud storage is its trustworthiness. Sadly, not everyone can construct belief in nameless people storing their knowledge. Even when the info is encrypted or secured, it nonetheless rests with one or many unaffiliated contractors. This may be worrisome to some enterprises, who could desire the accountability of a longtime group. 

Fairly complicated

It’s not really easy to construct a decentralized cloud storage system. Had it been so, everyone would have been constructing it! Counting on a reliable, centralized accomplice to safe and handle your knowledge as a substitute can save a whole lot of effort and time for you and your IT division.

Decentralized vs. centralized storage at a look

Here’s a fast take a look at a few of the principal variations between centralized and decentralized storage, together with their controller, encryption, location, safety, and price.

  Centralized Storage Decentralized Storage
Controller Single group P2P community
Encryption No Sure
Location Central location A number of nodes
Safety Larger threat of safety breaches Safety incidents much less seemingly
Price Could be pricey at excessive volumes Comparatively cheap

Main decentralized storage platforms

Given the rising curiosity on this area, a number of decentralized cloud storage suppliers have emerged on the scene. A couple of of the most effective are Storj, Sia, and Filecoin.


Storj is a decentralized storage system the place customers lease redundant drive area and earn tokens. It has three main parts:

  • Storage Node: Shops the info. Every node is independently operated.
  • Uplink: The software program that communicates with the storage nodes and satellites.  
  • Satellite tv for pc: Acts as a mediator between Uplink and Storage Node and decides what information the nodes will retailer.

When a person uploads a file to the Storj community, it encrypts information utilizing AES-256-GCM symmetric encryption after which breaks them down into 80 items. This knowledge is then unfold throughout various geographies and ISPs. Doing so ensures no unauthorized person will get entry to your knowledge.

Storj shoppers pay for storage in STORJ cryptocurrency. The STORJ token is an ERC-20 token that contributors use to purchase or promote on the platform.


Sia is an open-source cloud storage firm that runs on blockchain expertise. It really works on the proof-of-storage (PoS) technique for creating knowledge blocks on the Sia platform. Whoever has additional area can lease it out (as lessor) within the Sia market to customers (lessees) looking for space for storing.

Sia has a singular two-coin system that incentivizes the traders of the Sia community to remain invested within the platform.

  • Siacoins: Sia miners can monetize their additional unused space for storing and earn rewards within the type of siacoin (SC)—the native utility token of the Sia platform. The availability of Siacoins will not be fastened and will be minted indefinitely. At the moment, there are over 40 billion Siacoins on this planet, and their quantity will solely continue to grow.
  • Siafunds: Siafunds make up the opposite element of the token system in Sia. Siafunds are used for revenue-sharing functions. Nonetheless, word that Siafunds are extraordinarily uncommon, as there are solely 10,000 Siafunds in existence, out of which the guardian firm already owns 8,600 Siafunds. 


Created by Protocol Labs, Filecoin is an open-source P2P community that enables customers to lease unused area from those that don’t require it. Filecoin additionally comes outfitted with cryptographic PoS and proof-of-spacetime mechanisms that allow shoppers to examine at any level if a storage supplier is definitely storing the info they’ve dedicated to storing.   

Filecoin has two kinds of miners:

  • Storage miners: Storage miners are inspired to lease as a lot space for storing as doable. They obtain rewards proportionate to the area they lease out.
  • Retrieval miners: Retrieval miners are miners who’re tasked with retrieving knowledge once they obtain a “get” request. 

Miners are paid in FIL, Filecoin’s native token, which is used to lease onerous disk area. 

Who ought to use decentralized storage?

The most effective use circumstances for decentralized storage are people and organizations in extremely regulated industries or utilizing extremely delicate knowledge, resembling authorities and healthcare, in addition to these with restricted budgets who require an affordable but safe storage answer.

Who shouldn’t use it?

Decentralized storage could also be a poor alternative for big, complicated organizations with a excessive quantity of knowledge. These organizations might want the comfort and dependability of a single accomplice with a direct assist group who they’ll work with to prepare and handle their info.

Backside line: Utilizing decentralized storage

At the moment, a number of gamers are doing a little implausible work in decentralized storage, however the expertise continues to be in its infancy. Though these storage techniques provide a number of advantages over CSPs, like larger safety and elevated privateness, it nonetheless has but to go absolutely mainstream, and plenty of organizations nonetheless desire the peace of mind of a big, unified firm. Step by step, as Internet 3 turns into a actuality, we count on to see extra customers—each people and organizations—transitioning in direction of decentralized platforms sooner or later.

We additionally analyzed the most effective choices for network-attached storage (NAS) in your on-premises storage wants.
