Talk on Blockchain Intersection with Space Threats : 07 Jun 2023

 

Talk on Blockchain Intersection with Space Threats : Geointelligence Conference 2023: CYBER SECURITY"

Date 07 June 2023

TALLINN MANUAL & GLOBAL ATTEMPTS IN CYBER WARFARE POLICIES

The presentation is one unique presentation peculiar to TALLINN MANUAL version 1.0 and 2.0. Along with is discussed cyber policy attempts of other countries.The Tallinn Manual has long been the flagship research initiative of the NATO CCDCOE. The original Tallinn Manual (published in 2013 by Cambridge University Press) addressed the most severe cyber operations followed by version 2.0. The presentation cover the origin details of why this manual arrived at the global scene and what followed around at the global attempts for framing the global cyber policy.

BRAVE Web Browser : How much advertisements I blocked in a week ?

Hello friends, herewith first I am sharing screen shots of my brave browser dashboard that I captured over a week from 30 Jan 2021 to 6 Feb 2021.The screen shots I have taken pertain to morning hours whenever I login for the day. I am generally on my PC for about 8-9 hours a day. I majorly watch YouTube videos and surf across multiple sites in a day that range from 50-100 at times. So what I am bringing out here that how many ads Brave browser has blocked in this duration and whilst this surfing times.

30 Jan 2021 : 70517 blocked : Counter 0

 31 Jan 2021 : 77744 blocked : Counter 7227  in day( i.e. 30 Jan 2021)

01 Feb 2021 : 92342 blocked : Counter 14598  in day( i.e. 31 Jan 2021)

02 Feb 2021 : 97440 blocked : Counter 5098  in day( i.e. 01 Feb 2021)

03 Feb 2021 : 105386 blocked : Counter 7946  in day( i.e. 02 Feb 2021)

04 Feb 2021 : 108354 blocked : Counter 2968  in day( i.e. 03 Feb 2021)

05 Feb 2021 : 112036 blocked : Counter 3682  in day( i.e. 04 Feb 2021)

06 Feb 2021 : 114870 blocked : Counter 2834  in day( i.e. 05 Feb 2021)

So,total ads blocked over a week is 44353 that deduces to approx average of 6336 ads/day. That's phenomenal to say. Each of these trackers would be definitely linked to thousands of other trackers also giving them unrestricted access to all the user behavior ,privacy and profiles. While there is not much a normal user can do about these trackers, I feel just blocking these thousands of ads will not make any one absolutely free of tracking,but still better than surfing without blockers. Because if the ad companies know that users are blocking by means of plugins and such browsers,they would have already found ways to still track you. After all that's their means of living and minting economy.

CQ 100: Meet India’s Most Influential Cyber Warriors

CYBER SECURITY : A Mathematical attempt to understand and interpret the mechanics behind

Well..after a long time of around few years I gave a talk that was exclusive to CYBER SECURITY otherwise I have generally hovered around Blockchain and bitcoin for quiet some time now.The unique thing about this presentation is the take on that I attempted. The difference between the usual presentations and this one is that I have tried to explain the technicals behind data collection and prediction through regression. While the common men isn't largely bothered about surfing anything, anywhere, anytime, believing what harm can one do if he has nothing to loose. But alas he should understand why is the need so.The strange patents that IT giants like facebook ,google ,MIcrosoft are currently holding and developing is worrisome to realise. The links below give the presenation download google drive link and the scribd direct link.

Installation Bitcoin core on UBuntu 18.0.4 LTS : Bitcoin Mechanics -1

With this first post special to Bitcoin core,over next few months I intend to do some exploring on the bitcoin mechanics part.This basically means playing with the blocks and blockchain vide few python based scripts.Will start from the installation part followed by other posts on extracting info from bitcoin blockchain. This post basically is straight forward installation with the following commands.Screen shots for info :

Firstly install snapd with the following commands

sudo apt update
sudo apt install snapd

goto https://snapcraft.io/bitcoin-core

 

 click green button install

after this installation of snapd,one single command as follows:

sudo snap install bitcoin-core

The effected screenshots are seen below :

Once installed ,you can check on the terminal...should see three bitcoin applications by tabbing

While the GUI shows as below

When you run for the first time,the GUI notification pops for asking for location of default directory for storing blocks.

Thereafter the blocks start getting downloaded with status of files downloaded visible....

Blocks downloaded status is seen below...this downloading around 287 GB as on date will take time as per download speed available.

The location of the blocks being downloaded will be at /home/bitcoin_scripts/snap/bitcoin-core/common/.bitcoin/blocks where bitcoin_scripts is the user name.

Next post we will see whats inside the block....

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...
