What are the best applications and decentralized and open source technologies with greater potential? List 2021

When you use instant messaging and send a chat, the data first goes through a server and then reaches the other user’s mobile.

In this way the system is vulnerable to attack by intruders and at the same time all technology depends on the hosting not stop working. Otherwise, the messages could not be sent.

To solve this problem there are decentralized apps or technologies and it is characterized because its members are connected to each other and directly, avoiding the use of a server. In the following paragraphs you will find more information on this topic.

What is a decentralized app or technology and what are its benefits?

Technologies, or decentralized apps (also called Dapps), are computer developments that are characterized by creating a decentralized network with a mesh structure among its members. Therefore, the members of the network do not have a single central administrator who regulates all the movements of the nodes.

In this way it is achieved that the control function of the records that are produced is decentralized, allowing the set of nodes to act as notaries. That is, they attest to the activities and records carried out by the other members of the network.

When the blockchain is used as a structure, greater agility between operations is achieved. This is because it is not necessary to flow data through a server or controller. In addition, it allows increasing security because Dapp users communicate directly and have their data encrypted in a P2P way .

Another of the characteristics of this type of technology is that smart contracts can be closed between the members of the network. By this we mean that, since there is a set of nodes that acts as a notary, it grants approval of the activity carried out by two or more members.

This is because the activity log cannot be erased on the blockchain. Therefore, by having access, all members of the network will be able to agree that the contracting between users was carried out.
