Have you heard of IPFS (InterPlanetary File System)? If you are not familiar with this technology, it is a decentralized file system also known as IPFS (InterPlanetary File System) that is revolutionizing the way data is shared and stored on the Internet. But what exactly is IPFS (InterPlanetary File System) and how does it work? Below we explain everything you need to know about IPFS (InterPlanetary File System).
IPFS (InterPlanetary File System) is a decentralized file system that is based on blockchain technology. Instead of storing the data on a centralized server, IPFS (InterPlanetary File System) distributes the data across multiple nodes in the network, making it more resistant to attacks or censorship. In addition, IPFS (InterPlanetary File System) uses a hash-based identification system to guarantee the integrity and immutability of the data.
How does IPFS work?
Unlike the most widespread system currently hosting centralized servers. When a user wants to access a file in IPFS, they must first connect to this network and the system will look for the file using a unique address called a “content identifier” or “CID”. The system looks up the CID on the network and finds the requested file by distributing the file fragments among the nodes on the network.
One of the advantages of IPFS is that it allows you to access files quickly and reliably, even if one or more nodes on the network are inaccessible. Additionally, by storing files in a decentralized manner, IPFS can be more resistant to attacks and censorship.
Una de las ventajas de IPFS es que permite acceder a los archivos de manera rápida y fiable, incluso si uno o varios nodos de la red están inaccesibles. Además, al almacenar los archivos de manera descentralizada, IPFS puede ser más resistente a ataques y a la censura.

What is a CID?
Each file or set of files stored on the IPFS network has a unique CID assigned to it. The CID is used to identify and retrieve the file from the IPFS network.
A CID is made up of two parts: the prefix and the content identifier. The prefix specifies the type of content identifier being used and can be one of several different types. The content identifier is a hash that is calculated from the content of the file. The full CID is a base58-encoded representation of the content identifier and prefix. For example, a CID might look like this: “zdj7WpbshZxq3PYGj9KUyhW8pfM3bBKkjZ4sK4Rzz8hvQxZ”.
CIDs are used to uniquely and reliably identify files stored in IPFS, and are essential to the operation of the IPFS network.
What is a HASH?
A hash is a mathematical function that takes an input of any size (known as a “message”) and returns an output of a fixed size (called a “digest” or “hash”). Hashes are used in a wide variety of applications, including data integrity verification, strong password generation, and database indexing.
One of the fundamental properties of hashes is that they are “reproducible”: given a message and a given hash function, the same hash will always be returned. Also, it is very difficult in a practical way to find two different messages that produce the same hash (this is known as a “collision”). These properties make hashes very useful for verifying data integrity and detecting unauthorized changes.
There are many different hash functions, each of which has its own specific characteristics and uses.
What do we mean when we say that IPFS is decentralized?
When we say that IPFS is a decentralized network, we mean that there is no single central point of control or authority in the network. Instead, any device connected to the IPFS network can act as a server or node, and can participate in file storage and distribution. This means that there is not a single place where all the files are stored on the network, but that they are distributed among many different nodes.
This decentralization has several advantages. First, it means that the IPFS network is highly resilient to attacks or failures at a single point, since there is no single place where an attacker or failure could severely affect the entire network. Second, decentralization also means that the IPFS network is highly resistant to censorship, as there is no single point of control that can be used to censor or block access to certain files.
In short, decentralization is one of the fundamental characteristics of IPFS, and it is what allows it to be so resilient and secure.

In conclusion, IPFS (InterPlanetary File System) is an innovative technology that is transforming the way data is shared and stored on the Internet. By using a decentralized file system based on the blockchain, IPFS (InterPlanetary File System) offers greater resistance to attacks or censorship and guarantees the integrity and immutability of the data. In addition, by allowing fragments of a file to be downloaded from multiple nodes, IPFS (InterPlanetary File System) speeds up download speeds and reduces the load on centralized servers. It is important to note that IPFS (InterPlanetary File System) is a constantly evolving technology and is increasingly being used to share and store data on the Internet.
