Use kubernetes to develop block projects on Hyperledger Fabric

Use kubernetes to develop block projects on Hyperledger FabricGood afternoon, dear Khabarovsk people.
 
I am a developer of the IBM scientific and technical center in Moscow. We are developing IBM products together with other laboratories around the world. If time allows and there is a desire, then we are allowed to use part of the working time for projects that are not the main employment. This approach expands the horizon and supports the creative spirit. For me, such an area is the development of block-based solutions on Hyperledger Fabric. Moreover, such projects have become in demand in our market.

How to fix the infrastructure after the tsunami

How to fix the infrastructure after the tsunami
 
While people start airplanes from the window, practice in the settings of proxy servers or even install dante on VPS , the various business faced with the real consequences of massive blockages in their processes.
 
You can treat different things in different ways, but when G Suite ceases to work or the cloud structure is like a natural disaster.

TON: Telegram Open Network. Part 1: Introduction, network layer, ADNL, DHT, overlay networks

TON: Telegram Open Network. Part 1: Introduction, network layer, ADNL, DHT, overlay networks
 
For two weeks Runet is making a noise about Telegram and the situation with its senseless and merciless blocking by Roskomnadzor. The ricochet touched many, but these are all topics for posts on Geektimes. Another thing surprised me: I still did not see at Habr any analysis of the TON network planned for the Telegram's launch - the Telegram Open Network. I wanted to fill this gap, because there is something to learn there - even despite the absence of official statements about him.
 
Let me remind you - there are rumors that Telegram has launched a very large-scale closed ICO, having already collected ...

The question of a million is

Perhaps many of you were wondering: how will the behavior of a smart contract change if its data weighs hundreds of megabytes and stores hundreds of thousands or millions of records? Will the transaction go up? How will this affect the network as a whole? Will some types of variables in solidity cope with a similar task better than others? We decided to personally find out the answers to these questions and conduct an experiment in our private Ethereum network, simulating the described situations. What of this turned out to read further in the article.

The register of packages on Ethereum

Today only the lazy one does not launch another useless project on the blockroom, in this lesson I will tell you how to do something that has practical application. As an example, let's take a package register like npm just using a digital signature, a decentralized Swarm store and smart contracts based on Ethereum.

Proof-of-Proof-of-Work on the fingers. On the way to a sensible blockade

Proof-of-Proof-of-Work on the fingers. On the way to a sensible blockadeThe blocking protocols should provide a consensus among the nodes of the decentralized system. Perhaps the most famous consensus algorithm can be considered "braked, but reliable, because the braked" algorithm of Proof-of-Work: each node, having a set of new transactions, sorts through a certain number of nonce, which is the field of the block. A block is considered valid if all the transactions inside it are valid and the hash function of the block header has some common feature (for example, the number of zeros at the beginning, as in Bitcoin):
 
 

Hash (Block {transaction, nonce,}) = 000001001

What is EVPN /VXLAN

What is EVPN /VXLANIn this article I will tell you what EVPN /VXLAN is and why the features of this technology seem to me attractive for use in data centers. I will not deeply immerse you in technical details, but I will focus on them only to the extent that it is necessary to get acquainted with the technology. Almost everything I will touch in this article is somehow related to the transmission of OSI second-level traffic between devices in one broadcast domain. There are many tasks of an applied nature that you can comfortably solve, having such an opportunity, one of the most familiar examples of such a task ...
