Smart contracts are programs that run on a blockchain and allow custom functionality to be implemented on an existing blockchain (that supports smart contracts). The term "self-executing" contracts and the claim that smart contracts can enforce contracts on their own are very misleading, as this independent execution is limited to the blockchain on which they run. Smart contracts are not to be … [Read more...]

Pros of Decentralized Finance (DeFi)
Decentralized finance (DeFi) is a blockchain-based form of finance that does not rely on central financial service providers such as brokers, exchanges, or banks to offer traditional financial instruments, but instead uses smart contracts on blockchains. DeFi uses a multi-layered architecture and flexibly composable building blocks. What Are the Advantages of Decentralized Finance … [Read more...]
What is JSON Web Token (JWT)?
A JSON Web Token (JWT) is a JSON-based access token standardized according to RFC. The JWT enables the exchange of verifiable claims. It is typically used to exchange a user's identity between an identity provider and a service provider in a third-party system. JWTs are particularly suitable for implementing "stateless sessions", as all authentication-relevant information can be transmitted in the … [Read more...]
What is Proof of Work (PoW)
In computer science, a proof of work (PoW) is a method that is intended to prevent the excessive use of a service, such as denial-of-service attacks or the mass sending of e-mails (spam). Proof-of-work usually represents the solution of a moderately difficult task by the user or his/her computer. The result, on the other hand, can be checked by the service provider without much effort. The idea … [Read more...]
What is Distributed Ledger Technology?
The term distributed ledger technology describes a technique used to document certain transactions. In contrast to the classic approach, in which a ledger is usually managed by only one entity, any number of copies of the ledger are maintained by different parties in a decentralized manner. Appropriate measures will be taken to ensure that new transactions to be added are adopted in all copies of … [Read more...]
How Does Laser Engraving Work?
Laser engraving is the process of marking of objects with the help of an intense laser beam. In contrast to laser printing, in which a weak laser beam is only used to control the pigment application on the printed material, laser marking changes the labeled material itself. The process and the energy input therefore depend on the material. Laser markings are waterproof and smudge-proof and very … [Read more...]
How Ultrasonic Cleaning Device Works
Ultrasonic cleaning equipment is often used to clean small, complex and finely structured components, for example, jewellers, goldsmiths, dental technicians, watchmakers and opticians use ultrasonic cleaning baths to clean their products. The system consists of a liquid-filled, possibly heatable tub, one or more ultrasonic transducers or ultrasonic transducers and a generator that supplies the … [Read more...]
What is the Role of ChatGPT in Chatbots
ChatGPT is a chatbot that uses artificial intelligence to communicate with users through text-based messages and images. It uses modern machine learning technology to generate responses that sound natural and are meant to be relevant to the conversation. The chatbot was trained in several phases. It is based on the GPT-3.5 language model (GPT stands for Generative Pre-trained Transformer), … [Read more...]
Benefits of Unsupervised Learning
Unsupervised learning refers to machine learning without pre-determined targets and without any reward from the environment. The machine learning tries to recognize patterns in the input data that deviate from the structureless noise. An artificial neural network is based on the similarity to the input values and adapts the weights accordingly. There are several things that can be learned. … [Read more...]
Real-Time Location Tracking Explained
Real-time locating system (RTLS) also known as real-time tracking system is the determination of the location of an identified object at an initially unknown location without further determination of the associated orientation. This makes it possible to determine the location and whereabouts of objects, vehicles or people and link them to their identity. Positioning requires a well-defined … [Read more...]
