Workshops on the development of smart contracts on Solidity

Workshops on the development of smart contracts on Solidity
 
We bring to your attention videos of a series of workshops about smart contracts in Ethereum. Our goal is to show companies and ordinary people how to use smart contracts, what advantages they can give in various fields of activity. We want them to enter the everyday life, become clear and close to everyone. And we believe that in the future the overwhelming majority of paper contracts and other interactions in the society will be replaced by smart contracts.
 
Today our main task is to create a community of programmers and inspire them to use smart contracts. This is why we conduct our regular workshops.

The Messenger of Everything

All existing instant messengers have their pros and cons, but each of them pulls the blanket on its side because of its incompatibility with others - and this hurts users.
 
A single standard could be XMPP, but it, unlike E-Mail, appeared relatively late and did not have enough time to gain enough audience so that corporations could not abandon it. After all, they quickly realized that without holding an audience inside their own ecosystem, there was not much to gain. And besides, we must admit that XMPP had enough flaws due to the abundance of extensions, many of which, despite their importance...

Multi-signature on the Monero

Multi-signature on the Moneronetwork.We open a series of publications about the device of various blockers and begin research with monero (Monero). This is a well-known crypto currency, it has implemented a number of interesting algorithmic and cryptographic solutions. A few months ago, support for multi-signatures was added to Monero Core, and in this article we will take a closer look at this technology.     Multi-signatures are a mechanism for creating and using public purses. The concept itself is not new, it is already implemented in some crypto-currencies, such as Bitcoin, Ethereum and others. Its essence lies in the joint ...

Blanchane - a cure for the main diseases of modern education  
 
At the end of 201? the European Commission presented a report on the prospects of using blockade in education. Experts suggest using technology to combat counterfeit diplomas, making payments, providing personal finance and loans for training. Add to this the providers of online courses in symbiosis with the world's leading universities and get the image of the education industry of the future.

Adaptation of the blocking to the Internet of things: the main problems

About ten years ago, the number of devices connected to the Internet exceeded the number of network users. It was a turning point in the history of mankind - the Internet of people turned into the Internet of things. In this article we will consider the main problems of this phenomenon, as well as the possibilities of their solution with the help of blocking technology.
 
 
Adaptation of the blocking to the Internet of things: the main problems  
 
The concept of IoT (internet of things) was formed in 199? but at that time few could imagine how difficult it would be to integrate smart devices into everyday life.

Simple and powerful short-term smart contracts

Simple and powerful short-term smart contracts
 
Recently, smart contracts are widely used in the Ethereum network mainly for ICO and management of released tokens. Such contracts exist as much as necessary for the maintenance of projects, with months ensuring uninterrupted interaction with thousands of customers. We will call them long-term smart contracts.
 
However, certain tasks require that the contract is executed literally in minutes, after which it becomes unnecessary. And for each user may need special parameters, implement them in a large contract is not appropriate. Such contracts will be called short-term. Let's consider them in more detail ...

What is a smart contract: a short guide

The idea of ​​smart contracts appeared back in 199? when Nick Szabo suggested using a distributed global code to store information about transactions. To date, they are considered a very promising technology that can greatly simplify and secure many areas of life. Let's see how the "smart" contracts are arranged and why they are needed.
 
 
What is a smart contract: a short guide  
 
A smart contract is a computer algorithm in a blocking environment. It allows you to enter into and maintain transactions, as well as automatically fulfill their terms.
 
The main "trick" of this technology is that it allows you to eliminate intermediaries from the ...

TON: Telegram Open Network. Part 2: The blockades, shuffling
 
This text is a continuation of a series of articles in which I consider the structure (presumably) preparing for the release this year of the distributed network Telegram Open Network (TON). In of the previous part I described its most basic level - the way nodes interact with each other.
 
Just in case, let me remind you that I do not have any relation to the development of this network and will gather all the material from an open (although untested) source - document (there is also attached ...
