Intro However, while they may appear technically simple, building your own blockchain digital wallet equipped with advanced security features provides you the ultimate level of control over your funds and assets. In addition to this, as an open-source protocol, blockchain digitization continually adapts itself around customer needs. This ensures a frictionless customer experience across every transaction and storing platform. Thus blockchain technology will not lose its relevance in the world of cryptocurrencies and DeFi. ...

Proof of Reserve Proof of Reserve is a concept that aims to increase transparency and security in the management of assets. It is particularly relevant for cryptocurrency exchanges, which hold a large amount of user funds in their custody. Proof of Reserve allows users to verify that their funds are actually held by the exchange and not used for other purposes. Proof of Reserves in real world assets Proof of Reserve (PoR) is a concept that is not only relevant to the cryptocurrency world but also to real-life asset management. In the context of security assets, such as gold, silver, or other precious metals, Proof of Reserve is a way to provide assurance to investors that their assets are held securely by a custodian. In this article, we will explore how Proof of Reserve can be implemented in Solidity, the programming language used for writing smart contracts on the Ethereum blockchain, for real-life assets. ...

What are zero knowledge proofs? A zero-knowledge proof is a way for one person (the prover) to prove to another person (the verifier) that they know something without revealing any additional information about it. It’s like a magic trick, but with math instead of rabbits and top hats. Zero knowledge proofs (ZKP) are a type of cryptographic protocol that allows one party (the prover) to demonstrate to another party (the verifier) that a certain statement is true, without revealing any additional information beyond the truth of that statement. In other words, a zero knowledge proof allows one party to prove to another party that they know a certain secret, without revealing the secret itself. ...

Blockchain Technology and its influence in the Banking Industry Blockchain technology is rapidly transforming various banking industries. The decentralized and secure nature of blockchain is a game-changer in the financial industry which offering numerous benefits over traditional databases. In this article I will discuss how blockchain is changing the banking sector and why it’s becoming an essential technology for banks. Increased Transparency and Security One of the most significant advantages of blockchain technology is its transparency. The decentralized nature of blockchain ensures that every transaction is recorded on a public ledger that can be verified and checked by anyone on the network (who has access to the network). This transparency eliminates the risk of fraud and ensures that all transactions are accurate and secure and in traditional banking systems, there is always a risk of hacking or theft. With integration blockchain can be the risk is significantly reduced making it an ideal technology for banks. ...

Intro ChatGPT, a language model developed by OpenAI, has revolutionized the way we think about programming and software development. With its advanced natural language processing capabilities, ChatGPT has the potential to significantly improve the efficiency and accuracy of programming tasks. One of the most exciting applications of ChatGPT in programming is its ability to assist developers with code generation. By analyzing code samples and understanding the developer’s intent, ChatGPT can generate new code that is both syntactically and semantically correct. This can save developers a significant amount of time and effort, and can also lead to fewer bugs and errors in the final product. ...

Intro For several weeks I tried to play around bitcoin script. Yes, this may be news to you but bitcoin have a scripting language that acts as a very simple smart contract. This is an interesting topic because it reveals the internals of Bitcoin. What you should know is that bitcoins script is a scripting system for transactions. Forth-like, Script is simple, stack-based, and processed from left to right. It is intentionally not Turing-complete, with no loops. ...

Intro Rust is a modern programming language that focuses on thread-safety and performance. Unlike in many higher-level programming languages, there is neither a garbage collection nor a virtual machine in Rust. Instead, Rust addresses known problems of long-established low-level programming languages such as C or C++. At the same time, the programming language is known for its steep learning curve, which makes many developers shy away from delving into Rust. We provide four reasons to show that Rust, despite its complexity, has benefits that will make your work (and live) with the language easier. ...
