Abstract. There is a growing number of sensors, cameras and measuring devices in the public space. Why are they hanging on the lamp post? What are they measuring? And by whom? Those questions are relevant to the citizens to be assured that no private and sensitive data are collected without their approvement. At the same time the municipalities feel obligated to be transparent about the hanging devices to the inhabitants and provide a good working registration tool to the owners of the measuring devices. The sensor owners would also value the clarity about the process to register their devices and uniformity in the legislation if they plan to install their devices throughout more cities. We cannot forget about researchers, developers and data scientists who would highly appreciate the transparency about the measuring devices and the potential access to the data from the sensors.A National Sensor Registry (SensRNet) seems to be the solution to answer the abovementioned questions. The registry would: provide transparency to the municipalities and citizens about the data collected by the devices and the purpose for collection; provide overview and insight into where sensors are placed in public space and who is the owner; allow sensor owners to register the devices in a uniform way; provide access to highly demanded data to utilize the smart city concept; act as a platform that provides transparent, safe and secure environment where citizens and entrepreneurs can get more information or make objections against the reason behind collecting data.

ÖzDağıtık defter teknolojisi verilerin dağıtık olarak saklandığı ve yönetildiği yeni bir yaklaşım sunmaktadır. Mevcut merkezi sistemler güvenlik, güvenilirlik ve kesintisiz çalışma konusunda sorunludur. Verilerin tek bir noktada tutulması sunucuların siber saldırılara açık bir merkez haline getirilmesine neden olmaktadır. Bunun yanında merkezi sunucuların yöneticileri veya saldırganlar verileri manipüle edebilmektedir. İnternete bağlı cihazların sayısının artmasıyla merkezi sunucuların tüm istekleri karşılayabilmesi giderek zorlaşmaktadır. Tüm bu problemleri gidermek için dağıtık defter teknolojisinin kullanıldığı çalışmalar artmaktadır. Dağıtık defter teknolojisinde veriler dağıtık olarak tutulduğu için tek bir saldırı noktası oluşmamakta ve veriler hiçbir katılımcı tarafından değiştirilememektedir. Katılımcılar birbirleri arasında merkezi bir sunucu olmadan aracısız işlem yapabileceği için işlem yoğunluğu ne kadar fazla olursa olsun sistem kesintisiz olarak çalışabilmektedir. Dağıtık defter teknolojisinin teknik olarak açıklandığı ilk makale 1991 yılında yayımlanmıştır. İlk yaygın kullanımı 2008 yılında ortaya çıkan Bitcoin kripto parasıdır. Bitcoin, küresel finans sisteminin çöktüğü 2008 yılında Satoshi Nakamoto tarafından geliştirilen aracısız ve güvenli ödeme sistemidir. Bitcoin kripto parasının popüler hale gelmesi ile birlikte arkasındaki dağıtık defter teknolojisi olan blok zinciri ile ilgili farklı sektörlere yönelik çalışmalar yapılmaya başlanmıştır. Yapılan çalışmalarda blok zinciri teknolojisinin hız ve ölçeklenebilirlik açısında yeterli olmadığının görülmesi nedeniyle Hashgraph, Tangle, Holochain ve Tempo dağıtık defter teknolojileri geliştirilmiştir. Bu makalede mevcut dağıtık defter teknolojileri ile savunma, siber güvenlik, sigorta, tedarik zinciri, dijital hak yönetimi, sağlık, enerji ve finans alanlarında nasıl kullanılabileceği açıklanmıştır.

“…After the introduction of the first generation of blockchain embodied in bitcoin, two generations of blockchain have emerged that make blockchain applicable not only in finance and economy, but also in health, science, art, culture, social networks, and IoT (Chang et al, 2020 ; Masood & Faridi, 2018 ; Swan, 2015 ). So, many firms try to employ this innovative platform for different purposes (Lee, 2019 ).…”

“…So, many firms try to employ this innovative platform for different purposes (Lee, 2019 ). However, blockchain faces some drawbacks, such as scalability (Chang et al, 2020 ; Drescher, 2017 ; Masood & Faridi, 2018 ) which refers to slow procedures of creating new blocks due to the sequential nature of the Network. To overcome this issue of scalability, another type of DLT known as Directed Acyclic Graph (DAG) (Thulasiraman and Swamy, 2011 ) was introduced.…”

“…This feature increases the transaction per second of the cryptocurrencies that are based on the DAG much faster than the cryptocurrencies that are based on the blockchain. In addition, there would be no need for miners (Masood & Faridi, 2018 ). Nano is the first cryptocurrency that was developed based on the DAG (LeMahieu, 2018 ), and it is best suited for the internet of things and micropayments.…”

Quantiles dependence and dynamic connectedness between distributed ledger technology and sectoral stocks: enhancing the supply chain and investment decisions with digital platforms

2022

Distributed Ledger Technology (DLT) is highly applicable in various fields, especially the supply chain in many sectors. Against limited empirical evidence, this paper analyzes the relations between the Kensho Distributed Ledger Technology Index and stock indices of 12 sectors, including communication services, consumer discretionary, consumer staples, energy, health care, financials, industrials, information technology, materials, utilities, and real estate, and ESG by employing the quantile coherency and dynamic connectedness techniques. Our results reveal that the quantile coherency between the DLT stock index and the sectoral stock indices in almost all cases is significant and positive. The positive co-movement tends to be stronger in the longer terms and as we move from the lower to the higher quantiles, implying that they are more strongly connected in the long term and during the bearish market condition. Moreover, the dynamic connectedness indicates that the DLT stocks and the sectoral stocks are highly connected, with the former being a net transmitter of spillover shocks. The spillovers are also time-varying, and the results significantly corroborate those of the quantiles coherency methods. Among other relevant implications, DLT can be an important factor in the development and enhancement of these sectors.
