Payment channels allow parties to utilize the blockchain to send transactions for a cheaper fee. Previous work has analyzed to which degree a party can profit by facilitating the transaction process. The aim is to increase the usability of the network and to be rewarded for providing this service. However, previous work focuses on maximizing the...

Lightning is a natural phenomena that can be dangerous to humans. It is however challenging to study thunderstorm clouds using direct observations since it can be dangerous to fly into thunderstorm clouds. In this study, cloud radar with millimeter wavelength is used to study the properties and dynamics of thunderstorm clouds. It is based on a...

There is an everlasting arms race between censoring bodies and those in its grip. When the censor is employing increasingly sophisticated techniques to digitally monitor and restrict those in its scope, equally sophisticated means to circumvent the digital repression come forward. Those suffering under digital censorship are using nifty ways to...

The Lightning Network (LN) is a second-layer solution built on top of the Bitcoin protocol, allowing faster and cheaper transactions without compromising on decentralization. LN is also designed to be more anonymous, since less information has to be shared with the entire network. This should, in theory, improve privacy as well. However, recent...

Blockchain technology is the underlying mechanism that many cryptocurrencies operate on. It relies on cryptographic techniques that enforce integrity on transaction records. The records (blocks) stored are limited in size and frequency. One well-known issue regarding blockchain technology is the lack of scalability. In order to mitigate this...

The Bitcoin Lightning Network is a layer-two solution that promises instant payments, scalability, and low transaction fees on top of the Bitcoin blockchain. In case there is no direct channel between the sender and receiver, the routing algorithm uses source routing and a shortest path algorithm to determine the hops in a transaction. However,...

The LND is currently the most popular routing algorithm used in the Lightning Network, the second layer solution to Bitcoin’s scalability. Despite its popularity, recent studies demonstrate that its deterministic nature compromises the anonymity of the Lightning Network. In other words, threatening parties present in the transaction path can...

Popular cryptocurrencies lack scalability. Payment Channel Networks (PCN's) allow a large increase in transaction throughput. However, transaction failures are frequent when transactions are routed through multiple intermediaries. A previously introduced protocol, Interdimensional SpeedyMurmurs, increased the success ratio of transactions in PCN...

The Lightning Network is a second layer payment protocol built on top of Bitcoin, which is scalable and has reduced transaction fees. It does so by eliminating the need to broadcast every transaction to the whole network. When one user wants to send a payment to another, the routing protocol generates a path between them that is always fast and...

The Lightning Network aims to solve Bitcoin's scalability problem by providing a way to transact with minimal use of the blockchain. Instead, payments are routed over payment channel networks. This routing is done by LN clients, which use cost functions to compute the optimal transaction path. With the use of onion routing, LN tries to hide the...

Lightning, the prevailing solution to Bitcoin's scalability issue, uses onion routing to hide senders and recipients of payments. Yet, the path between the sender and the recipient along which payments are routed is selected such that it is short, cost efficient, and fast. The low degree of randomness in the path selection entails that...

With the aid of the analytical formulas of the disc pair model inter-shielded by different type of shield wires, the total series capacitance of the disc pair could be calculated. After introducing a number of inter-shield pairs to the disc pair model, the influence on the mutual inductance between discs has been thoroughly discussed. Last but...

To ensure a safe power system which operates correctly, a proper grounding system is necessary to provide connections to the ground at specific points. A grounding system is generally designed: (1) to reduce voltages occurring in the grounding system for short circuit situations (at power frequency) to an acceptable level in terms of step and...

Mass reduction is one of the main drivers for aircraft design. A big potential for saving mass can be found in part joining. Currently, most parts are joined by mechanical fastening. However, mechanical fastening requires labor intensive work and results in a weight increase especially for composite parts that, due to the mass saving they allow,...

Nonlinear voltage distribution along the transformer winding during a lightning overvoltage can cause severe electric stress specially to the area of the winding close to the high voltage terminals. For high voltage transformers different methods such as interleaved winding, electrostatic shield wires, and wound-in shield wires are implemented...

Blockchains such as the Bitcoin facilitate the online transaction between users without an intermediate financial institution and can serve as a global currency. However, at the moment, blockchain solutions are suffering from low transaction throughput and high delays. For instance, the bitcoin network processes at most 7 transactions per second...

The use of esters as transformer insulation has been gaining increasing interest over the past few years because of their better environmental performance, higher resistance to the influence of moisture and for some particular liquids, higher flash point as well. However, in order to completely replace the traditional mineral oil and be...

This chapter gives an extensive overview into the nature of the environment that luminaires and thus LEDs are subjected to during the event of a lightning stroke. Direct lightning stroke almost always results in instant damage for low-voltage connected devices, except in “extraordinary circumstances” where random components may survive. This is...

Lightning data is not only important for environment and weather monitoring but also for safety purposes. A device that monitors and keeps track of occurrences of lightning strikes has been developed. A communication interface is established between the sensors, data logging circuit and the microcontroller. The digital outputs of the lightning...

Transients from lightning strikes can enter underground cables at overhead line to power cable transitions. Possible overvoltages on these surges at cross-bonding connections of the cable screens are of major concern. A model is developed for modelling overvoltages from transient signal propagation through a combined cross-bonding cable and box....
