In a world full of new technology, the risk of fraud is constantly increasing. In the securities industry, this risk existed long before the use of technology. Congress enacted the Securities Act of 1933 to combat the risk of fraud and misrepresentation in the sale of securities. By requiring full disclosure, investors have the opportunity to make informed decisions prior to investing. However, Distributed Autonomous Organizations (“DAOs”), through the use of blockchains and smart-contracts, engage in the sale of securities without fully disclosing the risks or complying with the registration requirements of the Securities Act of 1933. Compliance with the burdensome requirements of registration, however, would destroy this new technology and method of conducting business. To avoid this set-back, Congress must amend the registration requirements to provide an exemption for DAOs. This exemption, although reducing current registration burdens, must still require DAOs to disclose certain information, thereby ensuring investors are informed prior to investing. Furthermore, due to the unique nature of the blockchain, smartcontract, and DAOs, Congress must impose a fiduciary duty on the creators of DAOs to ensure compliance with the disclosure requirements. Further, Congress should consider the allowance of burden-shifting following the initial crowdsale.

Mounting deanonymization attacks on the unreachable Bitcoin nodes – these nodes do not accept incoming connections – residing behind the NAT is a challenging task. Such an attack was first given by Biryukov, Khovratovich and Pustogarov based on their observation that a node can be uniquely identified in a single session by their directly-connected neighbouring nodes (ACM CCS’15). However, the BKP15 attack is less effective across multiple sessions. To address this issue, Biryukov and Pustogarov later on devised a new strategy exploiting certain properties of address-cookies (IEEE S&P’15). Unfortunately, the BP15 attack is also rendered ineffective by the present modification to the Bitcoin client.

Predicting currency prices remains a difficult endeavour. Investors are continually seeking new ways to extract
\nmeaningful information about the future direction of price changes. Recently, cryptocurrencies have attracted
\nhuge attention due to their unique way of transferring value as well as its value as a hedge. A method proposed
\nin this project involves using data mining techniques: mining text documents such as news articles and tweets
\ntry to infer the relationship between information contained in such items and cryptocurrency price direction.
\nThe Long Short-Term Memory Recurrent Neural Network (LSTM RNN) assists in creating a hybrid model
\nwhich comprises of sentiment analysis techniques, as well as a predictive machine learning model. The success
\nof the model was evaluated within the context of predicting the direction of Bitcoin price changes. Findings
\nreported here reveal that our system yields more accurate and real-time predictions of Bitcoin price fluctuations
\nwhen compared to other existing models in the market.

Abstract Blockchain technology is transforming traditional financial systems. Cross-border money remittance industry is in a crossroad being challenged. The traditional SWIFT system is facing new comers like Ripple system which is based on the blockchain distributed ledger technology with its own crypto tokens. This paper conducts a SWOT analysis on both technologies to find out whether the blockchain technology has the potential to transform a traditional industry and how this may be possible. We conclude that Ripple has all of the advantages over SWIFT despite some minor issues. In short-term, SWIFT will still take the lead in the remittance market due to the economy of scale. However, in long-term, emerging technology like Ripple will eventually revolutionize the remittance industry or even other financial systems.

Distributed ledger technology (DLT), commonly referred to as 'blockchain' and originally invented to create a peerto-peer digital currency, is rapidly attracting interest in other sectors. The aim in this paper is (1) to investigate the applications of DLT within the built environment, and the challenges and opportunities facing its adoption; and (2) develop a multi-dimensional emergent framework for DLT adoption within the construction sector.

Consensus is arguably one of the most fundamental problems in distributed computing, playing also an important role in the area of cryptographic protocols as the enabler of a secure broadcast functionality. While the problem has a long and rich history and has been analyzed from many different perspectives, recently, with the advent of blockchain protocols like Bitcoin, it has experienced renewed interest from a much wider community of researchers and has seen its application expand to various novel settings.
