A DApp, short for Decentralized Application, is a type of software application that runs on a decentralized network, such as the blockchain, rather than on a centralized server. DApps are designed to be transparent, immutable and decentralized, meaning they are not controlled by a single entity or individual. Instead, they are built on a decentralized …
Consensus algorithms are a fundamental aspect of the blockchain. They are mechanisms designed to validate, confirm and aggregate transactions to the blockchain, which in turn allows the integrity and security of the information stored on the blockchain to be maintained. There are many types of consensus algorithms, each with their own advantages and disadvantages. Some …
Cryptographic proofs are an important aspect in technology and within them, there are some very interesting ones using blockchain, such as zero knowledge proof. These algorithms allow proving that a user has certain information without sharing it. In a zero knowledge proof, there are two parts: a verifier and a demonstrator. The verifier is in …
Blockchain, smart contracts and federated learning technologies have revolutionized the way transactions are conducted and data is protected. However, many people may find it difficult to understand these concepts. For this reason, this article will explain one of these technologies in a simple way using an example.
