And so here we find ourselves in the year of our lord 2021. Global crypto market capitalization is approaching $2 trillion. PayPal is launching a crypto checkout service. Lindsay Lohan is shilling Tron. The Dogecoin Super Bowl commercial didn’t happen, but Elon’s taking it “literally” to the moon instead. Our ascendancy is complete. Crypto is mainstream. But, even today, getting your hands on certain crypto assets can be a bit of an epic journey.
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.

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 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 transitional storage.
The article will be particularly useful for those, who want to write their first smart-contract in TON but has difficulties where to start.
Using the lottery smart-contract as an example, I will show the path from the environment set up till publication of the smart-contract and its interaction. Moreover, I will create a website that will show smart-contract data.
Annotation. This article gives an analogy between the forces of nature and various types of money. A justification for the "money conservation laws" is made. Explanation of the IT-money phenomenon by analogy to physics laws is given, as well as gold and currency money. The transition from the gold and currency to the gold-currency-computing economy is considered. A reasonable assumption is made that the fourth type of money after gold, securities and IT money will be so-called "citation indices" or "ratings", which are similar in their properties to stock indices.
This article is an attempt to understand what money is from the physics and econophysics points of view. Econophysics (economics and physics) is an interdisciplinary research field, applying theories and methods originally developed by physicists to solve problems in economics, usually those including uncertainty or stochastic processes, nonlinear dynamics and evolutionary games.

This week I spent coding my very first public pet-app based on Telegram chat bot which acts as a Bitcoin wallet and allows to send and receive tips between Telegram users and other so-called “Lightning Apps”. I assume that you are familiar with Bitcoin & Telegram in general, i’ll try to post short and without deep jump into details. More resources about Bitcoin can be found here and Telegram is simply an instant messenger that allows you to create your custom apps (chat-bots) using their platform.
something like this…
From idea to implementation: modifying the existing elliptic curve signature scheme to be deterministic and providing functions on it to obtain verifiable within the blockchain pseudorandom numbers.
I like PHP for development speed and excellent portability. It's great to have such a tool in your pocket, always ready to solve problems.
For me it was quite sad that there was no Waves Platform SDK for PHP when i first met this nice blockchain. Well, I had to write such kit.
