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 …
Decentralized finance (DeFi) has emerged as an alternative to traditional financial services, allowing users to operate in an autonomous ecosystem without intermediaries. Thanks to blockchain technology and economic incentives, DeFi protocols offer a wide variety of services, from stablecoins to insurance and portfolio management. However, the lack of regulation and the presence of legally undefined …
Over the past few years, we have witnessed the emergence of a new form of decentralized finance known as DeFi, or decentralized finance. This innovative technology uses blockchain and smart contracts to offer a wide range of financial services without the need for traditional intermediaries. DeFi has been hailed for its potential to democratize access …
Introduction The Internet, the network of networks connecting computers around the world, emerged in 1969 and has since undergone numerous technological and infrastructural modifications to become what it is today. The initial purpose of the Internet as a means of sharing information has evolved over the years, and the web has become an essential part …
Nick Szabo, an American computer scientist and cryptographer, is considered the creator of the Smart Contract concept in 1997. Szabo described in his article “Smart Contracts: the future of legal agreements” how contracts could be managed by computers, referring to traditional contracts, which are agreements written on paper that require human intervention for their execution. …
The electric mobility sector is experiencing exponential growth in recent years and, with this, new challenges have been arising in optimizing the relationship between the different agents involved in this sector. The use case of GREEN, a platform under development, seeks to address these challenges through the use of advanced technologies such as Blockchain, Smart …
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 technology and smart contracts have revolutionized the way people think about finance and the reliance on central intermediaries. Decentralization in finance (DeFi) is an experimental way to offer traditional financial instruments without relying on banks, exchange platforms and other centralized financial services. In a decentralized system, the verification of financial transactions rests with the …
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. Federated Learning technology has become an essential tool …
