ICO 2.0 and business tokenisation

Hello, Khabravchans! I am a programmer with 15 years of development experience. In due time it was possible to work both on accounting systems, and over financial tools and web sites. I found the developer those days when OpenSource was still called a waste of time and watched from the very beginning its evolution into a key engine of technology.
 
 
Now there is a very high HYIP around crypto-currencies and investing in ICO. Knowing how the open technologies influenced the development of this industry, we, with my colleagues from the current work, believe that ICO is the next round in the financing ...

Asymmetric cryptography with a one-time secret key: description of the idea and possible application

Asymmetric cryptography with a one-time secret key: description of the idea and possible application  
(to understand what is said in this article, it is necessary and sufficient at least in general terms to imagine what is asymmetric cryptography and how the electronic signature works)
 
 
The script for using a one-time secret key is:
 
 
 
A key pair consisting of a secret key (secret key, SK) and an open (public key, PK) key is created.
 
A number of operations are performed using the secret key. The first of these, the creation of a public key, has already been completed in the first step.
 
At first glance, an antilogical action is performed - the secret key is destroyed without the possibility ...

We begin work with EOS Mainnet for 10 minutes

We begin work with EOS Mainnet for 10 minutes  
 
The launch of the EOS network was the most anticipated event of this summer for the community of crypto currency developers. Now that the network is running (albeit with flaws), we all can not wait to start developing applications on EOS.
 
 
I will not argue about the problems with the launch and the general EOS model, but I will give just a brief introduction so that all those who wish can immediately try their hand at development.
 
 
This is what I will discuss in this article:
 
 
 
The easiest way to connect to the EOS Mainnet
 
How to use wallets and accounts
 
How resources are allocated

Top 10 new block projects in 2018 - Forbes

Practically all the reviews that came to my attention were written in order to provide information about top-level crypto-currency and lock-up companies that are worth paying attention to and, in fact, all of them mentioned Bitcoin and Ether. The only problem is that these companies are not new and most people who are interested in this topic know or have heard about them. Thus, the reviews did not provide any new information. However, there is a huge number of noteworthy companies and besides Bitcoin and Ether. Therefore, in my article, I want to explore this topic deeper and create an updated ...

Introduction to smart contracts. Their potential and real limitations are

Introduction to smart contracts. Their potential and real limitations are
 
This is perhaps the most interesting article about the prospects for applying smart contracts in business practice, which I came across (though, there were not so many of them). It is written by lawyers and published in late May on the Harvard website. Although the US example, the text reveals issues such as the application of legislation to transactions on smart contracts, the problem of understanding the parties of the code, the problem of oracles, risks, and others.
 
Including, you will find an explanation why vending machines (as an example of the most visual and simple implementation of a smart contract) ...

How will the revolution in decentralization change the world economy?

How will the revolution in decentralization change the world economy?
 
The bitcoin revolution and the crypto currency predicts the beginning of the currency century.
 
 
The current system of economy largely depends on trusted third-party organizations to ensure, verify and control the cash flow throughout the world. This dependence has led to corruption, inefficiency and uncoordinated incentives in the system.
 
Userfeeds
 
Userfeeds is working on what they call "Proof of Importance," a decentralized protocol for determining the degree to which information meets the needs of consumers. They look at the degree to which information meets the needs of consumers as the ...

A guide to owning accounts and contracts in Ethereum

A guide to owning accounts and contracts in Ethereum
 
The material, which we decided to publish today, was born about 6 months ago and has still not lost its relevance (maybe it had to be refreshed a little). Then we were still able to be surprised, looking at businessmen and start-ups, intending to conduct ICO, but not being able to make a transaction with the translation of one ether. Today we are no longer surprised, but these characters are not much less.
 
In general, understanding the importance of secure storage of your secret keys and the ability to do this is the basis of a decentralized economy, which, we hope, will soon substantially push the classical ...

High-Mining: the newest version of PoW-blockade protection against "51% attack"

High-Mining: the newest version of PoW-blockade protection against "51% attack"
 
 
Fork developers Litecoin Cash presented a preprint of technical document ' The Hive: Agent-based Mining in Litecoin Cash ', in which they described their proposal for the protection of a crypto-currency blockage operating on the basis of the proof-of-work algorithm from the "51% attack". Their solution combines mining with outdated ASIC devices (SHA-256) and democratic virtual mining using "working bees" (HiveMine). In the case of a competent implementation, the LCC block will decide one of the biggest problems of modern block projects (from Bitcoin to Ethereum): the threat of an attack when more ...

Do you need a blockade?

Do you need a blockade?Hello Habr! I bring to your attention the translation of articles «Do you need a Blockchain»
 
 

Part 1 (Supply Chain Management)


 
Blocking was presented as a technological innovation capable of leading to a revolution in social relations and trade. This reputation is partly related to its properties allowing non-trusting parties to interact and change financial assets without relying on a trusted third party.
 
 
In this article, we critically analyze whether the block is really the best solution for a particular usage scenario.
