Uso do algoritmo H1 na Forense da Blockchain

UFU - Universidade Federal de UberlândiaTrabalho de Conclusão de Curso (Graduação)Nos últimos anos, as criptomoedas estão cada vez mais populares entre os usuários e estão sendo utilizadas em atividades lícitas e ilícitas. Sendo assim, é necessário desenvolver fer ramentas e técnicas para analisar esse ecossistema das criptomoedas, a fim de fiscalizar as atividades realizadas nesse contexto. Nesse trabalho, serão apresentados alguns conceitos da Blockchain e da criptomoeda Bitcoin. Além disso, serão citadas algumas atividades ilegais que utilizam o Bitcoin como forma de pagamento. Em seguida, serão apresenta dos algumas ferramentas de análise da Blockchain e como são realizadas essas análises. Posteriormente, será apresentado o algoritmo H1 que é um algoritmo de agrupamento que utiliza os endereços de entrada de uma transação para produzir clusters de endereços que muito provavelmente pertencem a mesma entidade no mundo real. Este trabalho é finalizado com a implementação e aplicação do algoritmo H1 em um caso real de forense. Além disso, com os resultados obtidos nesse trabalho foram adicionados novos endereços aos endereços iniciais extraídos do caso analisado

Food Blockchain

The article aims to highlight the main elements that must be taken into account in the case of food traceability, from producer to final consumer, by using blockchain technology or in other words how this technology borrowed from the field of cryptocurrencies can revolutionize food chain management Throughout the chain from production, storage, transport, to the final consumer, the complexity of food management and tracking is difficult to carry out. What makes blockchain technology stand out, is the solution to consumer confidence in the product they are buying. It is required that the seller at the end of the chain assume the quality level of the product, for which the buyer pays. In this sense, there are several international retailers that have developed this technology for their own products, with the aim of reducing food fraud

Decentralized Public Ledger Systems and Securities Law: New Applications of Blockchain Technology and the Revitalization of Sections 11 And 12(A)(2) of the Securities Act Of 1933

When Bitcoin launched in 2009, it was the first virtual cryptocurrency to gain popularity and attain widespread use. Much attention has been paid to Bitcoin’s well-publicized advances and setbacks as the world’s foremost virtual currency. Less attention has been paid, however, to the decentralized public ledger technology that enables Bitcoin to function. That technology is just as innovative as Bitcoin itself. Decentralized public ledgers are a revolution in digital data storage and have the “potential to fundamentally shift the way in which society operates.” This Note will examine one such societal shift—a change in how shareholders access and assert their rights the securities markets. Specifically, this Note proposes that decentralized public securities ledgers will enable private shareholders to more fully access the protections of Sections 11 and 12(a)(2) of the Securities Act of 1933 in cases of securities fraud. To facilitate understanding of this new technology, Section I describes the history and function of decentralized public ledger networks. It provides an overview of common ledger formats, and details current and future applications of the technology.Section II examines how decentralized public ledgers relate to the securities markets at both the national and state levels. It details how the Securities and Exchange Commission (“SEC”) plans to implement and regulate the use of decentralized public ledgers and explains how Delaware is currently using the technology to create new classes of corporate stock. Lastly, Section III of this Note posits that applying decentralized public ledger technology to securities transactions will increase the number of plaintiffs who are capable of achieving standing under Sections 11 and 12(a)(2) of the Securities Act of 1933 (the “Securities Act”). After detailing the history of Section 11, Section 12(a)(2), and the tracing doctrine, Section III explains how decentralized public securities ledgers will transform the tracing doctrine from a nigh-insurmountable pleading burden to a simple records search. It will help a wider scope of plaintiffs meet the judicially-imposed tracing doctrine. Although making this burden easier to fulfill will expand the potential plaintiff pool, and thus may create logistical issues for courts and defendants, the internal structure and pleading requirements of the Securities Act will effectively limit frivolous suits. This, in turn, will better fulfill the statutory language and remedial intent of Sections 11 and 12(a)(2) of the Securities Act

Smart Contracts, Blockchain, and the Next Frontier of Transactional Law

Smart contracts are an emerging technology that could revolutionize commercial transactions by eliminating inefficiencies and uncertainty created by the current transactional ecosystem of lawyers, courts, regulators, banks, and other parties with divergent interests. However, a lack of consensus around how smart contracts are implemented, uncertainty regarding enforceability, and scarcity of on point statutes and case law means that a stable legal, commercial and technical smart contract landscape has yet to emerge. The implementation of universal legal, technical and commercial standards and best practices will reduce uncertainty and promote widespread adoption and use of smart contracts

Decoding Smart Contracts: Technology, Legitimacy, & Legislative Uniformity

Blockchain technology is increasingly permeating the everyday lives of countless people. Applications of the cutting-edge technology range from secured banking to tracking mortgage titles. A particular blockchain technology, dubbed “smart contracts,” has the potential to revolutionize how individuals and companies securely contract with each other. Smart contracts, however, are not widely employed, mainly because potential users are uncertain of their enforceability as contracts under existing state contract laws. Similar skepticism slowed the acceptance of electronic signatures in the late 1990s, but was resolved ultimately through a model uniform act recognizing electronic signatures’ effectiveness across interstate borders. This Note proposes a similar solution for smart contracts based on a review of current state legislative developments and existing laws regulating blockchain technology
