As NFTs spread across the world, users spent millions of dollars to buy digital assets to prove their uniqueness. Many creators and artists showcase their beautiful products, such as artworks, music, etc., in the NFT marketplace. What if a creator can profit from their work even after selling it to another business? This is where royalty comes in; it is a recent addition to the NFT space. Owing NFT royalties can benefit artists and creators from succeeding sales to the business. 

Once NFT royalties became a hot topic and gained popularity among artists and creators. Later, arguments were evolved to remove royalties that had swayed other NFT creators. DeGods, the popular Solana's NFT project, has moved its royalty model to 0%. However, creating a royalty-based NFT marketplace attracts many creators around the world. In this article, we will delve into the development process of NFT marketplace royalties and how it benefits enthusiastic artists from secondary sales. 

Let’s imagine you need access to the real-time data of some smart contracts on Ethereum (or Polygon, BSC, etc.) like Uniswap or even PEPE coin to analyze its data using the standard data scientist/analyst tools: Python, Pandas, Matplotlib, etc. In this tutorial, I’ll show you more sophisticated data access tools that are more like a surgical scalpel (The Graph subgraphs) than a well-known Swiss knife (RPC node access) or hammer (ready-to-use APIs). I hope my metaphors don’t scare you ?.

The following text consists of two logically connected parts. The first part constructively rules out the assumption that untraceability supposes anonymity. The second part enumerates specific practical tasks in the form of various scenarios when digital signatures (DS) do not provide correct solutions to the task. It is demonstrated that a complete solution can be obtained through a special combination of DS and an interactive anonymous identification protocol.

The National Internet Segment Reliability Research explains how the outage of a single Autonomous System might affect the connectivity of the impacted region with the rest of the world. Generally, the most critical AS in the region is the dominant ISP on the market, but not always.

As the number of alternate routes between ASes increases (the "Internet" stands for "interconnected networks" - and each network is an AS), so does the fault-tolerance and stability of the Internet across the globe. Although some paths are more important than others from the beginning, establishing as many alternate routes as possible is the only viable way to ensure an adequately robust network.

The global connectivity of any given AS, whether an international giant or a regional player, depends on the quantity and quality of its path to Tier-1 ISPs.

Usually, Tier-1 implies an international company offering global IP transit service over connections with other Tier-1 providers. Nevertheless, there is no guarantee that such connectivity will always be maintained. For many ISPs at all "tiers", losing connection to even one Tier-1 peer would likely render them unreachable from some parts of the world.

Pretty much everyone in the IT community is talking metaverses, NFTs, blockchain and cryptocurrency. This time we will discuss metaverses, and come back to everything else in the letters to follow. Entrepreneurs and founders of tech giants are passionate about this idea, and investors are allocating millions of dollars for projects dealing with metaverses. Let's start with the basics.

The spread of cryptocurrencies contributed to the development of many solutions based on a distributed ledger technology (blockchain). Although the scope of these solutions varies, most of them have the same basic set of security services, i.e. confidentiality, authenticity, and integrity. These features are granted by the practical applications of public key cryptography, in particular,  digital signature (DS). But unlike many other applications of public key cryptography, cryptocurrency networks do not use public key certificates. This is the aspect that we would like to talk about.

Hello, everybody!

My name is Alexander Zubkov and today I’d like to talk about routing loops.

Smoothly the era of mesh-networks is upon us. At the very least, the term is appearing more and more often in the information sphere. What attracts the attention of networkers? Let's try to understand the question, taking Yggdrasil network as an example as one of the most promising prototypes. The article is intended for a wide range of readers.

The DHT system has existed for many years now, and torrents along with it, which we successfully use to get any information we want.

Together with this system, there are commands to interact with it. There are not many of them, but only two are needed to create a decentralized database: put and get.

Blockchain is a decentralized technology that maintains a record of all transactions occurring over a peer-to-peer network. Due to Blockchain's several different high-level use cases, numerous industries described Blockchain as the 'magic beans.' 

Blockchains store the record in a decentralized system that is interconnected. This technology lessens vulnerability and enhances transparency in all industrial sectors as information is stored digitally, and it does not have any centralized point to carry out the transactions.

Do You Know?

We are a team of independent developers. We have created a new messenger, the purpose of which is to solve the critical problems of the modern Internet and the modes of communication it provides. We see users become hostages to the services they have grown accustomed to and we see corporations exploiting their users and controlling them. And we don’t like it. We believe the Internet should be different.
In this Manifesto, we disclose our vision of the Internet and describe what we have done to make it better. If you share our ideas — join us. Together we can achieve more than each of us can alone.

What is this article about?

In this article, I will tell about my participation in the first (out of two so far) Telegram blockchain contest. I didn't win any prize. However, decided to combine and share the unique experience I have had from the start to finish line, so my observations could help anyone who is interested.

Since I didn't want to write some abstract code, instead make something useful. I created instant lottery smart-contract and website which shows smart-contract data directly from Telegram Open Network (TON) avoiding any middle storage layers.

The article will be particularly useful for those, who want to write their first smart-contract for TON but don't know where to start.

Using the lottery as an example, I will go from setting up the environment to publishing a smart contract, interacting with it. Moreover, I will create a website that will show smart-contract data.
