Blockchain is a new technology for performing transactions, often compared to the Internet which revolutionized the way one shares/sees Information. It was first conceptualized by an anonymous person or group of person known as Satoshi Nakamoto in 2008. A Blockchain, in the simplest definition, is a ledger of transaction from the time of its genesis. Transaction is any transfer of a tangible/non-tangible asset within the people associated with that Blockchain. Bitcoin is just one of the many application whose core technology is Blockchain.In most of the transaction, there are three parties involved: the sender, the receiver, and the trusted verifier whose role is to verify that the transaction has actually taken place. For instance, one transfer money via bank through cheque, by money wallet; or one lease out a property after performing certain kind of paperwork implying Government as a trusted authority. A Blockchain removes the necessity for a third party to verify the transaction. This also implies that the Blockchain is robust to fraudster and fraudulent transactions.A Blockchain, visually or programmatically, is nothing but a chain of blocks where each block is a set of transactions. Every block contains information such as current timestamp, a link to the previous block and the next block, a collection of valid transactions during the time period between the formation of previous block and current block. Its network consist of working nodes called miners, whose main work is to create new blocks. These new blocks are joined in a single, continuous, authorative record called Block Chain. Whenever a new transaction takes place, it then propagates to the peers of the originating node and so on, till it exists with the whole network. Now the miners’ job is to validate the transaction and create the block by collecting a set of transactions. Creating a block is computationally expensive cryptographically challenging task. Once such a new block is created it is added to the chain and is then transferred back to the whole network. The other receiving nodes in the network adds the block to the existing ledger after validating the block. If one were to alter any transaction in a fraudulent way which had already taken place, they would have to find a new block that would include that transaction to fit the chain. If the current block to be computed in the network is at number 88, and the altered transaction block was 79, then the person will have to find 9 (79-87) more blocks to make a valid blockchain and pass it to the peer network. This is theoretically possible but is not in real world since finding block is not an easy task, making blockchain an ever increasing, irreversible, secure and public ledgerBitcoin, a very popular digital currency, relies on Blockchain. Applications of Blockchain is not limited to digital currency, it can be used to create smart contracts that execute on fulfilling a certain criteria (ex. Ethereum), for instantaneous peer-to-peer transaction without third parties (ex. In stock trading, property trading, patents), etcTo conclude, Block Chain is a distributed ledger of important transactions stored on a decentralized peer-to-peer network which is incorruptible due to high computation costs of blocks making it irreversible creating a trustworthy network to transact removing the need of middleman.

StoryMirror interviewed ThirdWatch and all about their venture. Here is what they have to say.Q. Tell us about yourself and your backgroundThirdWatch is about stopping fraud in digital transactions. We are avid e-commerce shoppers and has been shopping online since 2005 indiaplaza days when we used to order books online. Couple of years back I was trying to order TV for my Dad who lives in Greater Noida on one of the top 2 e-commerce sites of India however it was not taking the order despite being prepaid. When I ordered the same item to my Gurgaon address it came through. On digging deeper we found that fraud/abuse is a big problem in e-commerce and companies sometimes use broad rules like blocking certain pin codes/cities/states and/or international credit from ordering which affect genuine users part from fraudulent.Given our experience in building big data mobile analytics system we felt confident that we can solve this problem by using Ai and big data hence started ThirdWatch in April 2016.Q. What's is your business all about?Our platform Mitra prevents fraud in digital, banking and e-commerce transactions in real time using AI. Our system captures 200+ parameters and flag every transaction in real time as red or green. It generates a risk score also which defines riskiness of the transaction.By superimposing data from our own knowledge base and from third party databases we enhance the data captured from user transaction like zip code databases , ip address databases, mobile number validity databases. We also use micro models for address profiling, device signature, account profiling and velocity profiling. We capture the whole user behavior including the time taken to place order, the device user is using to order, ip address of user, location of order amongst others.We are very stringent on data security and sign a strong NDA with our clients however we do use networks effects to multiply effectiveness of our platform by collating fraud patterns across the client base and inputting values in our ML algorithm for e.g. fraud rate of email domain, fraud rate or zip code, area and many more.Q. How do you see yourself in next 5 years? In near future we would expand to South East Asia, in long term we will expand into preventing other financial frauds including Insurance and fintech fraud.Q. Message to your customers and viewersFor every customer, Thirdwatch has always been a profit centre and never a cost centre. E-Commerce companies can avail a free 2 months trial, and can actually validate the benefit we are offering themselves.Q. Which are your main clients? What is the process of integrations? How successful have you been in controlling such fradulent cases in India for these companies?Traction has been phenomenal since we launched, We are currently processing about 5000 transactions per day with a pipeline to reach 50000 transactions per day. Because of our NDA’s and agreements with our client we will not be disclosing clients list, but we are working with two of the top10 E-commerce Companies of India Q. What is the background of the founders? How big is the team?Adarsh Jain (36) and Shashank Agarwal (28) came up with the idea of ThirdWatch and utilising Artificial Technology to prevent fraud in the e-commerce domain. A few years ago, Adarsh tried to buy a Television set from a leading e-commerce website from his father’s residential address in Noida. The order was unsuccessful due to the location from which it was ordered. The same order could be processed, however, from his Gurgaon address. The problem intrigued Adarsh and he started to research and find the root of this problem. He got to know about the problem e-commerce sellers face, relating to fraud and abuse by fraudulent sellers. Shashank and Adarsh have prior experience with technology solutions, with multiple patents and patent applications in their names individually. They thought of combining their efforts to come up with an all-in-one, smart solution for e-commerce platforms. With a team of 10-15 people at such an early stage of ThirdWatch, the business is growing at a tremendous pace. More people will be on-boarded soon as and when the business expands to other cities and countries.Q. Is your technology scalable to a level wherein it can be used in govt offices or banks? If yes, please give the details on when do you plan on expanding there.Currently, ThirdWatch enables e-commerce businesses to prevent fraud and abuses they come across in form of promo code abuses, chargeback frauds, RTOs, Cash on Delivery frauds, identity frauds, and much more. ThirdWatch's AI- Mitra can be definitely used by Government agencies and banks to detect fraudulent users and block risky transactions. With regards to banks, Mitra can be easily employed to detect fraudulent credit/debit card payments, fake users, multiple accounts held by users to make fraudulent transactions, etc. Mitra can also be useful in the Digital India and Cashless society initiatives undertaken by our Government. There are numerous websites and apps that enable us to transfer money, complete e-KYC, file returns, etc. However, the risks associated with these apps are similar to the risks faced by e-commerce sellers. With AI, detecting and preventing fraud for the Government and Banks is easily plausible!Q. Data security being the Crux in today's internet era, how do you ensure maintaining that? ThirdWatch ensures complete security of the data provided by our clients with its strict Non-Disclosure Policies and Security Measures. The data provided is only used for analysing it and highlighting the transaction into 'risky' and 'fake' transactions. The security parameters are never compromised, and we maintain unmitigated security standards for the data we receive from our clients.Social Media Handles - Facebook - https://www.facebook.com/thirdwatchai/LinkedIn - https://www.linkedin.com/company/thirdwatch-data-pvt-ltd/Twitter - https://twitter.com/thirdwatchaiG+ - https://plus.google.com/u/0/b/110280512617140226197/110280512617140226197Youtube - https://www.youtube.com/channel/UCWWWl8h50-w5xuek0GtUEKQ

In this whole wide world, where we are engulfed by the modern age technology , we tend to forget that is not a substitute for Grandma’s stories. We develop this ideology that the most valuable things are inevitably materialistic. Our mindsets are inflicted upon this idea and we forget that presents cannot buy presence. Technology has taken over the current situation. We stand in the middle of an era where we have Netflix on the tips of our fingers and Swiggying is the new cool. Technology is like that attractive magnetic pole to which we are iron nails disguised in the dust of development and modernization. On one hand it offers irresistible devices, and Mark Zuckerberg is our new hero, it is also an addition to our lives that has grappled our throats and choked us from within. Technology at its very best is an idyllic tool which is in every way a priceless possession to us. Yet it is high time that we rise from our lives barred by technology, and make judicious use of it. We are busy making connections worldwide but reckless we are to bother about the people we connect with for a lifetime. We have developed the way of life with standards set by Instagram posts and Google is our life guide. We are surrounded by lashes of social media and Google is our 2 am friend. Our lives, to be more specific have ‘technologized’ and it is not that there are no perks of this so called elixir of human life. It exposes us to the world watching us with watchful antagonism. It is a window to the world we desire to be a part of. We are no less than modified creations who have adopted technology in every realm. In this so called paradox called life, we are lost in the chaotic streets of technology, where Google and Face book reside, that we miss on the little things in life. And any person who thinks small things don’t matter, has not seen a match start a wildfire. We are building tall buildings, but our minds are narrow. We talk about development in the name of technology, but our values have certainly diminished. Unnerved by the amount of time we devote to technology oriented activities, we are in the want of something more. But at the cost of what? But let us not forget how technology has given us the tag of the modern man. Let us remember the times it has sorted ways and hardships in life. All this can be accepted only if we don’t get abolished from our roots, which is the base of our existence. Let us embrace technology as an assistance, rather than a bossy fellow who indeed has conquered our lives and harnesses the very essence of it. We shall never forget the popularization of PubG and Fortnite, all credits to our very own tech based lives, due to which our studies reduced to being acknowledged once in a fortnight, and also the Wikipedia posts we have always relied on, or has Quora taken over that position? I am in the middle of a dilemma in this fussy world encompassing of Pinterest in the heart and Google within the soul. Let us wake up to the situation and resist constant dependence on technology. Let us not completely despise ourselves. Afterall, Byju’s will be our eternal ally whenever disguised obstacles in the name of Maths hit our way. We as humans have accepted technology and have adjusted according to the acceptable conditions of it as well. It is high time we put in arduous efforts and restrain ourselves from this very a developing addiction. Nonetheless, no matter how extensively we try to change ourselves, we will have this medium called technology, always by our side. After all, we are humans.
