Review on Blockstack by Saparov Meylis

Blockstack is a decentralized network that allows the creation of dApps and provides maximum data control to users. The platform's creators are positioning it as an alternative to traditional cloud computing. Blockstack has already raised over $ 75 million in funding and looks like one of the most promising crypto projects in 2019.

Blockstack allows you to:

* do not worry about storing information when creating

databases. DApps developers can completely

focus on working out the logic of your

applications. The network participants will provide the place themselves

for storing information. Through decentralization

data security problems are also solved, information

stored on multiple PCs, destroy it irrevocably

an order of magnitude more difficult compared to

centralized databases;

* solve the problem of scaling. In the traditional

client-server model to scale

increase the number of servers. Usage

Blockstack will allow every web user

allocate part of the space for storing data and part

computing power for the necessary calculations;

use smart contracts;

* implement decentralized authentication

user. It will be possible to abandon traditional

methods used for 2-factor

authentication is used instead

cryptographic signature;

* use STX tokens as local currency.

Let's note the active community, hundreds of

dApps running on Blockstack.

More details on the technical component can be found in the White Paper. Below is a brief description of the key elements.

Blockstack consists of the following elements:

* Stacks Blockchain is a proprietary blockchain. Initially

the Bitcoin blockchain was used, but in parallel

created its own;

* Gaia is essentially a giant file system, any

can use it to store data. Wherein

the user encrypts his data himself and chooses where

they will be stored - in the cloud, on the local

or remote media. Enhanced security

provided by the fact that applications are available

only hashes, but also to them at any time the user

can close access;

* Blockstack Authentication - when used

platform, the client receives a universal name, a single

for all applications. Not necessary for everyone

come up with a unique username and password like this

happens with regular applications. Protocol

Blockstack Auth provides user verification;

* Blockstack Libraries and SDK - a set of tools for

developers. The project depends on the community, therefore

everyone can create their own applications.

Blockstack developers applaud this.

Blockstack also includes dApps Market (market for decentralized applications) and Blockstack Browser. The developers say that when using this browser, interaction goes directly with other users, that is, the data is not downloaded from the servers.
