This work evaluates the impact of Blockchain technology, reviewing its principles, accelerated growth, and immediate and long-term direction, emphasizing a special focus on activating this technology for the real estate sector, through a descriptive, predictive, and fundamental analysis of pioneering companies in the field. This is supported by a financial modeling methodology backed by backtesting and market capitalization weighting, allowing the valuation of assets used by these companies over time and determining their stock market relevance. Finally, the results will be examined to conclude the current and future effect of Blockchain on the real estate industry, as well as its financial viability and feasibility, both in the United States and Colombia.
Análisis de pertinencia : modelo de implementación de blockchain en los contratos del sector público : el caso Corporación Gilberto Echeverri Mejía
(Universidad EAFIT, 2023) Álvarez Zapata, Erika Joana; Blandón Vélez, Evénide del Socorro; Escalante Gómez, Juan Esteban
This degree work aims to analyze the relevance of the Blockchain implementation model in public sector contracts. For this purpose, a research with a qualitative approach, descriptive scope and non-experimental design is developed, which analyzes, through three (3) steps (1 - identification and mapping of the risks associated with contracts, 2 - analysis of Blockchain technology, 3 - evaluation through a model of the applicabilities of Blockchain for the organization) the suitability of this tool in the framework of state contracting. The results reveal that this type of entities are exposed to multiple phenomena that may affect their operation (legal, operational, technological, financial, compliance, security, political and social, and reputational aspects are highlighted). In addition, it is shown that the Blockchain constitutes a tool that contributes to improve the conditions of digitization, security, transparency and traceability of data. Finally, a three (3) axis model is proposed (information, technology, security and eight (8) perspectives (protocols, codes, availability, infrastructure, access to platforms, connectivity, cybersecurity, confidentiality of information) that allows identifying variables and critical elements for the use of the tool in the public sector (in terms of privacy, trust, decentralization and speed for the different stakeholders).
Análisis de rendimiento de los patrones de integración event message y command message en sistemas distribuidos
(Universidad EAFIT, 2023) Gómez Vélez, Juan Felipe; Vallejo Correa, Paola Andrea; Correa Botero, Daniel
A distributed system is composed of a set of interconnected autonomous computers. Using integration patterns is common in these systems to facilitate communication among computers in an asynchronous way. Event Message and Command Message, are among the most commonly used integration patterns. The performance of both patterns is analyzed in this study, considering the efficiency and the time taken to carry out a message transmission process, which may vary depending on the number and size of the messages. To carry out the analysis, the previously mentioned integration patterns were implemented in two different systems. Additionally, a comparison is performed for each pattern considering the following parameters: message size, messaging broker configurations, time between sending and receiving a message, and the name of the test type. In this way, the configurations and behavior of the integration patterns involved in the message exchange flow can be understood in a better way, as well as detect and prevent performance-related problems.

Blockchain, una oportunidad para el desarrollo de las asociaciones público-privadas en infraestructura en Colombia
(Universidad EAFIT, 2022) Álvarez Zambrano, Óscar Javier; Restrepo Tobón, Diego Alexander
This article investigates the way in which Blockchain technology can solve some frictions in the financing of infrastructure through Public-Private Associations, in Colombia. This is key to alleviate poverty and generate long-term growth, however, financing faces a decrease in capital, due to the increase in public deficits, transparency problems and the high cost of financing. This document makes an exhaustive review of the literature to study the potential of Blockchain in improving the efficiency of public finances and in attracting private sources to close the existing gap in infrastructure. The Blockchain impacts investment in infrastructure, democratizing participation in projects in three ways: i) Expanding the group of investors, attracting potential capital from small financiers, ii) Decentralizing the formulation of projects to institutions such as mayors and governors and iii) Proposing financial models that accommodate medium and small-scale projects such as secondary and tertiary networks. The Blockchain improves the liquidity of infrastructure assets, increasing transparency and trust and reducing transaction costs by facilitating access to different capitals.

The effects of globalization have made that supply chains (SC) became a major concern for most organizations. The number of actors involved within the SC make it an appealing target for cyber-attacks, corruption, and other threats that includes the flow of goods or information, therefore, there is an urgent need to start implementing actions that help to buffer the impact of such threats to keep a reliable SCs that guarantees a sustainable growth for all parties involved. Blockchain is one of the technologies that are part for the 4th industrial revolution, which its main purpose is to make sure the information flow among certain parties can be highly reliable by creating blocks that are immutable as soon as they are approved to keep transparency among all organizations. In this order of ideas, applying blockchain may be a useful technology to combat against threats that may harm the flow of information. The purpose of this paper is to create a blockchain proof of concept applied in an import-export process of a manufacturing firm to demonstrate the benefits this technology can provide for the safety, reliability, and transparency of the information flow from the creation of the purchase order up to its arrival to the designated location.

Internet de las cosas (IoT) es una tecnología que permite la interconexión de dispositivos a través de una red, ya sea entre sí o a través de internet. Esta interconexión facilita el control y monitoreo remoto de dispositivos en tiempo real, con aplicaciones que abarcan desde hogares inteligentes hasta sistemas industriales complejos de control de procesos y seguridad. En el entorno educativo actual, las instituciones de educación superior enfrentan desafíos significativos para formar profesionales capacitados en estas tecnologías. Para hacerlo se usan las plataformas IoT comerciales existentes las cuales imponen limitaciones como períodos de prueba limitados, capacidad limitada de datos y funcionalidades bloqueadas, para acceder todas las funcionalidades se deben parar costosas suscripciones. Para solucionar esta problemática, se desarrolla una plataforma IoT educativa completamente gratuita, diseñada específicamente para estudiantes de ingeniería, computación y áreas afines, esta plataforma no tiene ninguna de las limitaciones anteriormente mencionadas, adicionalmente la curva de aprendizaje para su uso no es tan alta como en otras plataformas.
