The exponential growth of healthcare Internet of Things (IoT) data necessitates secure, low-latency analytics that extend beyond centralized architectures. This paper presents BDAFL DNN, a blockchain-integrated data analytics framework that combines Federated Learning (FL) and Deep Neural Networks (DNNs) for real-time, privacy-preserving healthcare analytics across edge and cloud resources. Local devices such as smartwatches and phones collect noninvasive time series sensor streams (heart rate, temperature, and abdomen sensors), perform on device DNN training, and send only model updates to healthcare edge nodes, where a blockchain ledger validates updates for integrity and traceability; validated updates are then aggregated in the cloud via FL to produce a global model without sharing raw data. In a simulation study against representative baselines, BDAFL DNN reduced execution time, energy use, and resource consumption, lowered the deadline miss ratio, and improved blockchain validation correctness. These results show that integrating blockchain with FL-driven edge and cloud DNN analytics can deliver scalable, secure, and timely insights for future healthcare IoT systems.

This article examines the broader societal implications of blockchain technology and crypto-assets, emphasizing their role in the evolution of humanity as a "superorganism" with decentralized, self-regulating systems. Drawing on a process philosophy approach grounded in Stiegler's "general organology" and further informed by related concepts such as Nate Hagens' "superorganism" idea and Francis Heylighen's "global brain" theory, the paper contextualizes blockchain technology within the ongoing evolution of governance systems and global systems such as the financial system. Blockchain's decentralized nature, in conjunction with advancements like artificial intelligence and decentralized autonomous organizations (DAOs), could transform traditional financial, economic, and governance structures by enabling the emergence of collective distributed decision-making and global coordination. In parallel, the article aligns blockchain's impact with developmental theories such as Spiral Dynamics. This framework is used to illustrate heuristically blockchain's potential to foster societal growth beyond hierarchical models, promoting a shift from centralized authority to collaborative and self-governed communities. The analysis, grounded in sense-making through a philosophical and biomimetical approach, and aims at providing a holistic narrative and view of blockchain as more than an economic tool, positioning it as a transductive technological seed for the evolution of society into a mature, interconnected global planetary organism.

The surging popularity of cryptocurrencies presents both opportunities and challenges. While some view it as the future of finance, others remain concerned about investment risks. This uncertainty creates difficulties for consumers and financial institutions. To address this gap, the study assessed consumer perceptions of cryptocurrency investment risks and perceived usefulness, aiming to identify new avenues for transactions and investments. Employing a quantitative descriptive approach, a survey was conducted among 150 individuals from two (2) cities in the Philippines using a validated instrument and the Technological Acceptance Model (TAM). Results showed that consumers perceived moderate risk across trust, privacy, security, and financial aspects. No significant demographic variations were found in risk perception or perceived usefulness. These findings suggest a generally positive consumer attitude toward cryptocurrency investment despite the risks. This implies the possibility of widespread adoption if expectations align with the technologyโs actual capabilities. Ultimately, this study offers valuable insights into consumer decision-making, which can inform future risk management strategies in the cryptocurrency landscape. It focuses on a geographically under-researched population (Philippines). This research contributes valuable insights for policymakers and industry leaders developing strategies to promote responsible cryptocurrency adoption across diverse user groups, particularly in emerging markets.

The use of data mining techniques in the context of the behavioral economy of virtual assets based on social media data allows for a more accurate assessment of the price movements of cryptocurrencies. The study builds models for forecasting prices in the cryptocurrency market, taking into account the behavioral factors of stakeholders based on social data from the TikTok platform. The data for this study were obtained using social media application programming interfaces. The main stages of the study included data collection, processing and aggregation, scaling and correlation analysis, building and evaluating the relevant models. As a result of the study, key behavioral metrics of social networks are identified. Correlation analysis showed strong linear links between TikTokโs social performance and weak links to the price of bitcoin. The study builds linear models, polynomial regression, Decision Tree and Random Forest. Behavioral metrics such as the number of shares, likes, comments, shares, and views are used. Models are evaluated by testing with use of MSE and MAE metrics. The results suggest the limited effectiveness of linear regression for predicting the prices of cryptocurrencies due to the non-linear nature of the market. The Decision Tree model has shown some success in predicting bitcoin prices, however, deviations in forecasts have increased over time, especially in the face of market fluctuations. Polynomial regression and the Random Forest model demonstrate higher accuracy in forecasts. Based on the comparison of MSE and MAE indicators, the Random Forest turned out to be the most effective model for predicting bitcoin prices among those considered.
Blockchain are transparent, tamper-resistant, digital ledgers, implemented in a distributed network of peer-to-peer nodes, in which transactions are made securely and usually without the approval of a central and trusted authority.Thus, blockchains allow peer-to-peer nodes that do not have a trust relationship to exchange data without third parties or intermediaries.This data could correspond to money, contracts, land titles, medical and educational records, certificates, purchase and sale of goods/services, or any other transactions or assets that could be digitized.Blockchain offers lots of advantages, in finance, healthcare, government services, educational sectors, and the Internet of Things.Applying blockchain technology in educational systems will take the management of academic records and the issuing of graduatesโบ certificates to a higher level of trust, in addition to minimizing lots of work and costs.The proposed model calls for a unit within the Ministry of Higher Education using blockchain technology, that will offer a potential solution for student's data storage, students' exchange between institutions and certificates issuing and verification.This will lead to multiple advantages in decentralization, scalability, reliability, and security.
