BLOCKCHAIN: BEYOND HORIZON

BLOCKCHAIN: BEYOND HORIZON



"The blockchain cannot be described just as a revolution. It is  the tsunami-like phenomenon, slowly advancing and gradually enveloping everything along its way by the force of its progression"
A blockchain is a growing list of records, called blocks, which are linked using cryptography.
Each block contains a cryptographic hash of the previous block a timestamp, and transaction data.

 The main purpose of this component of blockchain technology is to create a  secure digital identity reference. Identity is based on the possesion of a combination of private and public cryptographic keys.
The combination of these keys can be seen as a dexterous form of consent, creating an extremely useful digital signature. 
In turn, this digital signature provides strong control of ownership.

 The three main properties of blockchain technology which has helped it gain widespread acclaim are as follows:

  • Decentralization
  • Transparency
  • immutability
Working of Blockchain:

One party to a transaction initiates the process by creating a block. This block is verified by thousands, perhaps millions of computers distributed around the net. The verified block is added to a chain, which is stored across the net, creating not just a unique record, but a unique record with a unique history. Falsifying a single record would mean falsifying the entire chain in millions of instances. That is virtually impossible. Bitcoin uses this model for monetary transactions, but it can be deployed in many other ways.

The reason why the blockchain has gained so much admiration is that:
·         It is not owned by a single entity, hence it is decentralized
·         The data is cryptographically stored inside
·         The blockchain is immutable, so no one can tamper with the data that is inside it.
·         The blockchain is transparent so one can track the data if they want to

Applications:
The blockchain gives internet users the ability to create value and authenticates digital information.
  •  AML and KYC: Anti-money laundering (AML) and know your customer (KYC) practices have a strong potential for being adapted to the blockchain. Currently, financial institutions must perform a labor-intensive A multi-step process for each new customer. KYC costs could be reduced through cross-institution client verification and at the same time increase monitoring and analysis effectiveness. Once verified through the bank data is cryptographically stored on block chain.
  •  SMART CONTRACTS: Smart contracts can be programmed to perform simple functions. For instance, a derivative could be paid out when a financial instrument meets a certain benchmark, with the use of blockchain technology and Bitcoin enabling the payout to be automated.
  • THE SHARING ECONOMY: By enabling peer-to-peer payments, the blockchain opens the door to direct interaction between parties — a truly decentralized sharing economy results.An early example, OpenBazaar uses the blockchain to create a peer-to-peer eBay.


The interesting thing about blockchain is that it has made it possible for humanity to reach a consensus about a piece of data without having any authority to dictate it.      "Everything will be tokenized and connected by a blockchain one day."

Pegasus Spyware: Flying Through The Air

 Hundreds of millions of people can't imagine life without their smartphones. Almost every aspect of their daily lives, from the most mundane to the most intimate, is within easy reach and hearing distance of their smartphones. Only few people realize that their phones may be used as surveillance devices, with someone hundreds of miles away secretly extracting their messages, photographs, and location while also activating their microphone and recording them in real time. Such capabilities are present in Pegasus, a spyware produced by NSO Group, an Israeli maker of mass surveillance weapons. What is Pegasus? Pegasus is a hacking software – or spyware – that is developed, marketed and licensed to governments around the world by the Israeli company NSO Group. It has the capability to infect billions of phones using either iOS or Android operating systems. The spyware is named after Pegasus, the white winged horse from Greek mythology. It is named so because it "flies through the...

8 TECH SUPPORT STORIES. A MUST READ!

MOVE THE MOUSE! I asked a user to move her mouse all the way to the right. They picked up the mouse physically and put it on the right side of her desk. RIGHT CLICK! I told the user to right click on the desktop to select properties. She replied that nothing was happening. I asked her again to do the same. She replied with the same answer. When I went to her desk, she had written the word CLICK on a paper on her desk. LAPTOP NOT WORKING! A user was once shouting at me that her laptop was not working even though she hit the keys and tried the touch pad. I run down to her, she shows her laptop still shouting that I wasn’t working properly and couldn’t do my job etc. I look at her laptop, switch it on, turn around and leave the room. OUTAGE PROBLEM! A user once asked if they could download “download the Internet” in case there was a power outage and they could still use it. COMPUTER WON’T TURN ON! Once, a user said that her computer won’t turn on. I asked her to check ...

HOW TO SEE INCOGNITO HISTORY AND DELETE IT

We have heard about private or incognito browsing. It’s the mode that doesn’t store anything in history. While it does store cookies, but are deleted after the session is exited. This mode is known as Incognito browsing in Google Chrome, Private Browsing in Mozilla Firefox, and InPrivate Browsing in Internet Explorer. Whatever we may want to call it, the mode works the same in all browsers. However, sometimes we might want to go back to a page that you previously opened. The question is – can you check your incognito history? Problem is, there is no easy way to go back to that page. So all are search queries we saw is effectively lost. Unless you can Google it up and it shows again. But if it’s not there on the first page of Google, it’s gone forever. But we can still get to know about the websites that have been browsed under the incognito mode. Yes, the private browsing mode has a loophole. You can see the browsing history of someone using incognito mode but only if you h...
