Merge in the Ethereum Blockchain: Technology development in a new and innovative industry

The food industry has been at the forefront of rapid implementation for several technological innovations. One of the main reasons for this is that food security has been of paramount importance in supplying a growing population, taking into account both quantitative and qualitative requirements. And the necessary development could only be ensured by incorporating the latest developments. Blockchain technology is also a tool to consider in terms of how it can help track food chains. Its widespread application is only a decade old, but in some areas, for example, the operation of cryptocurrencies has already accumulated enough experience to see if it really lives up to the hopes attached to it, and what problems still stand in the way of further spread. With this material, our primary goal is to present a significant technological change that aims to solve one of the main problems of blockchain-based data management. It will be presented how the technology works (with a specific focus on the proof of work mechanism) and the transition to a truly significant platform, the proof of stake mechanism at Ethereum. This gives us an idea of how much a relatively new technology can undergo changes, and at what rate a seemingly significant problem (in this case, e.g. environmental impact) can decrease. This potential for development provides the basis for counting blockchains as a technology that can be applied in other areas, such as the food industry. In addition to scientific treatises, we often rely on Internet sources in the material, since the change occurred so quickly that publications in scientific journals could not yet track it or only in a narrower circle

Zárójelentés (2006) Összefoglalás Cím: Lézerablációs és elektrotermikus mintabeviteli módszerek fejlesztése elemeloszlások atomspektrometriás vizsgálatára Az elemzendő minták elektrotermikus párologtatásával (ETV) vagy nagy teljesítményű lézersugárral végzett ablációjával (LA) keltett gőzökből szilárd aeroszol állítható elő hideg argon turbulens hozzákeverésével. A keletkező finom eloszlású aeroszol nagymértékű kicsapódás nélkül szállítható át induktív csatolású plazmamába (ICP), mely utóbbi fényforrásként vagy ionforrásként szolgál az optikai spektroszkópiai (OES) vagy tömegspektroszkópiai (MS) mérőrendszerekhez. A jelen kutatási periódusban a kétféle módszer elvi-elméleti sajátságait az aeroszol képződése szempontjából, egy megjelenés alatt álló könyvfejezetben tárgyaltuk. Kísérleti munkánkban az ETV módszer került előtérbe, melynek eredményeit három megjelent és egy megjelenés alatt álló közleményben ismertettük. Megállapításaink az ETV gázáramoltatásának optimálása, valamint a mintához vagy a gáztérbe adagolt kémiai módosítók kiválasztásában és hatásmechanizmusának felderítésében újszerűek. Ezen kutatásokban hollandiai (Delft) és németországi (Kempten) laboratóriumokkal működtünk együtt. | Development of laser ablation and electrothermal sample introduction methods for atomic spectrometry of element distributions By electrothermal vaporization (ETV) or laser ablation (LA) of samples dry aerosols are produced from the evolved vapor through a turbulent mixing with cold argon gas. The aerosol of high dispersion can be transported without an extensive loss into an inductively plasma (ICP), which can serve either as a light source for optical emission spectroscopic (OES), or as an ion source for mass spectroscopic (MS) measurement systems. In the four years period of research the fundamental characteristics of these two methods with respect of aerosol formation were described in a book chapter which is under publication. In the experimental work, the ETV method came into the forth, the results of which have been discussed in three published papers and in an accepted manuscript. Novel statements could be established to the optimization of the gas streaming conditions in the ETV units, and in exploring the mechanisms of action of chemical modifiers applied either to the samples or to gas phase of the furnace. These research works were done in cooperation with a laboratory in The Netherlands (Delft) and with another laboratory in Germany (Kempten)

And the necessary development could only be ensured by incorporating the latest developments. Blockchain technology is also a tool to consider in terms of how it can help track food chains.

Examination of digital circuits with simulation and measurement

We teach Digital Technology to the Students of the Óbuda University AMK for many years. In the curriculum there are lectures and laboratory exercises. Initially, all the measurements were performed with an oscilloscope, but later part of the measurements were simulated. From here came the idea to examine the operation of the logic circuits by simulation, then oscilloscope, and compare the results. We also made comparisons for combination and sequential networks. The results of this work are described in the article

Examining the Evolution of Technological Conditions from the Point of View of the Application of Blockchain-based Data Management in Food Supply Chains

A critical point in making food chains more sustainable is to find different ways to increase efficiency. These can be aimed at shortening the chain, using more sustainable raw materials, etc. Blockchain technology offers the potential for reliable data management and simplified administration and is, therefore, definitely a tool to consider if the aim is to enhance sustainability in food chains. The question arises as to whether food chain operators have the technology and knowledge needed for widespread uptake. The aim of this research was to investigate whether the technical background and knowledge for the use of cryptocurrencies can be compared with the technological background for monitoring the food chain with blockchain-based data management. If so, since data on the uptake of cryptocurrencies is already available, this analysis will provide information on the realistic scope of such an application. The research showed that there is no significant difference in the technology required for the two applications. The data clearly shows that, overall, there are 4.6 billion people who have the tools to use them. In addition, there is evidence that cryptocurrency penetration is weakly correlated with GDP or banking system development. In other words, if other conditions are right (e.g., the interest of producers), the availability of tools and knowledge should not be a barrier to uptake. Neither is the economic performance of a country or the development of its banking system. It is therefore concluded that, based on the aspects examined in this research, blockchain technology can be applied on a large scale worldwide
