Blockchain Technology Workshop : IIIT Raipur

Dr. SPM IIIT-Naya Raipur, established by the International Institute of Information Technology University Act,2013 of the Government of Chhatissgarh, is a joint venture by Chhattisgarh State Government and National Thermal Power Corporation (NTPC).A workshop on Blockchain Technology was organized from 28-30 Nov 2019 at the campus with the following aims:

(a) To disseminate the knowledge of Blockchain technology among students, researchers and academicians.

(b) To discuss the current status of the Blockchain development and research work in India and across the world.

HYPERLEDGER FABRIC ON UBUNTU 18.04 LTS : INSTALLATION STEPS WITH TERMINAL COMMANDS

Hyperledger is an umbrella project of open source blockchains and related tools, started in December 2015 by the Linux Foundation, and has received contributions from IBM, Intel and SAP Ariba, to support the collaborative development of blockchain-based distributed ledgers.The following post ahead will see through the screenshots and steps for installation of Hyperledger Fabric on Ubuntu 18.04 LTS. The installation basically first creates the required environs and then the actual installation of.

The actual terminal history I got after the installation is placed below.Between 11-13 terminal commands,if you get an error,please reboot and proceed.

    1  sudo apt-get update
    2  sudo apt-get install curl
    3  sudo dpkg --configure -a - i ran this owing to an error in between
    4  sudo apt-get install curl
    5  sudo apt --fix-broken install - i ran this owing to an error in between
    6  sudo apt-get install curl
    7  sudo apt-get install npm
    8  sudo apt-get install docker
    9  curl -fsSL https://download.docker.com/linux/ubuntu/gpg | sudo apt-key add -
   10  sudo add-apt-repository "deb [arch=amd64] https://download.docker.com/linux/ubuntu $(lsb_release -cs) stable"
   11  apt-cache policy docker-ce - might need a reboot if error seen
   12  sudo apt-get install -y docker-ce
   13  docker info
   14  sudo docker info
   15  sudo apt-get install -y docker-ce
   16  sudo apt-get install docker-compose
   17  sudo apt-get upgrade
   18  sudo curl -sSL https://goo.gl/6wtTN5 | sudo bash -s 1.1.0
   19  history
   20  sudo chmod 777 -R fabric-samples
   21  cd fabric-samples/first-network
   22  sudo ./byfn.sh generate
   23  sudo ./byfn.sh up


The following applications and software's need to be installed first for Hyperledger Fabric:

• CURL
• GO Programming Language
• Docker
• Docker Compose
• Node.js Runtime
• NPM
• PYTHON

The following is the set of commands used for the entire installation.These commands are followed by the respective screen shots of the executed commands.

So...all good and the fabric is installed...

GANACHE Blockchain installation UBUNTU 18.04 LTS

Ganache is a personal blockchain for Ethereum development one can use to deploy contracts, develop  applications, and run tests. It is available as both a desktop application as well as a command-line tool. Ganache is available for Windows, Mac, and Linux.This post will share few commands and screen shots to install Ganache in GUI mode in Ubuntu 18.04 LTS. It is an ethereum client which one can use for Ethereum development and is part of Truffle ecosystem. Ganache is used for the development of DAPP and once  developed and tested on the ganache,it can be deployed on any DAPP on ethereum client like geth or parity.

First step : Goto https://www.trufflesuite.com/ganache

 Second step : Click at the Download button.

 Third step : chmod a+x ganache**** to make it executable

 Fourth step as above...simply run the executable

 Its ready to go...

SUBLIME editor installation in UBUNTU 18.04 LTS

1. Sublime Text is a proprietary cross-platform source code editor with a Python application programming interface. It natively supports many programming languages and markup languages, and functions can be added by users with plugins, typically community-built and maintained under free-software licenses.The installation part of the same on Ubuntu will just take few commands as seen below and the sublime editor will be ready to go.The commands are listed below : 

First step

wget -qO - https://download.sublimetext.com/sublimehq-pub.gpg | sudo apt-key add -

(click on image to enlarge)

 Second step

echo "deb https://download.sublimetext.com/ apt/stable/" | sudo tee /etc/apt/sources.list.d/sublime-text.list

(click on image to enlarge)

Third step

sudo apt update

Proof of Sleep : Mind Boggling Consensus Algorithm

Introduction

Consensus is the backbone of the Bitcoin technology and is the reason for the Bitcoin to be widely famous since it mitigates the need for any third party mediation. Blockchain domain has around forty plus consensus algorithms as on date with many variants of Proof-of-Work ,Proof of Stake etc. 

"Proof of Sleep" consensus algorithm has been proposed to remove all existing energy dissipation issues in reaching consensus. This will also resolve complex cryptographic algorithms like DAG,Proof-of-Capacity, Proof-of-Burn etc at the click of a button. Welcome to the world of "Proof of Sleep", a new consensus algorithm wherein no energy issues and complexities are involved.

"Algorithm is based on the node admin in P2P sleeping time and essential vital parameters" as per the designer team based in Noida.

How it works?

The participating node admin will go to sleep as and when the need to attain consensus arises. More the number of people register at one node and more they sleep, the consensus is designed to get stronger and expedited. Thereafter the node breathe vitals and snoring decibels will be syncd with the "pre-sleep division" working in Washington, DC. The sole purpose of this division is to use the precog(nitive) potential of this node to prevent waking-up. The breathe vitals will include the exhale/inhale composition of gases. Once syncd,the cryptographic hash of the dreams will be recorded to generate an ultimate unique 4096 bit key. This will be back linked to the nearest person sleeping to this node which will be decided by the Open Shortest Path First (OSPF),an established routing protocol.

Completely based on dreams,the node thus has to fulfill certain QRs before being established as a node. The QRs for participation as a node have been submitted to ISO 14000 ,a series of environmental management standards.

Hyperledger ,the multi-project open source collaborative effort hosted by The Linux Foundation has taken keen interest to explore this. The Linux foundation plans to replace Apache Kafka in Hyperledger Fabric and RBFT in Hyperledger Indy with Proof of Sleep.

Satoshi ACTIVE again

Meanwhile as per fresh inputs received Satoshi Nakamoto's email id satoshin@gmx.com has got active this Friday again. Thus after a decade of sleep,Satoshi Nakamoto has consented to replace Proof of work with Proof of Sleep. This shows the kind of buzz and confidence this new consensus algorithm.  "Now that I had been sleeping over a decade,this algorithm fits fine and I intend replacing my proof of work with Proof of sleep. This will ensure that even as I sleep again, I would contribute to all the consensus taking place around " Satoshi Nakamoto mentioned in email, hinting at his sleep and vanishing act again.

Conclusion

Proof of Sleep is a turning point in the evolving domain of Blockchain and its consensus algorithms. The existing consensus algorithms have faced energy wastage issues across the globe. This path breaking algorithm is likely to shutdown all mining farms and pave way for a green consensus. Proof of sleep will bring the peaceful stone age earth times since maximum participating nodes will be in sleep mode. With maximum nodes sleeping,it couldnt have been better for a peaceful,no war,no ruckus earth,
