Blockchain Tech Is Ad Fraud’s Worst Nightmare – adbank

– Hi, I'm Chiron which in Greek mythology means wise centaur, but that doesn't matter right now Get, get

What does matter is I'm CTO of Adbank What's Adbank? Let me show you Right now if you're digital advertiser, you give your money to a middle man He takes a huge chunk of it and gives the rest to a publisher Adbank is the new platform that gets rid of this guy

Go on guys, take it It's yours Grab it Don't be shy How do we do it? A peer-to-peer advertising platform built on the blockchain

Don't know what the blockchain is? Ask your nerdiest friend – The blockchain is a decentralized ledger — – Not now Go hang out with horse man So how does this work without the middle man? You know how Uber doesn't own any cars They built a platform that connects people together directly

Well, it would be so cliche if I were to say we were the Uber of digital advertising so I won't say it, but I'll sing it ♫ We're the Uber of digital advertising I hate it when people say that – [Director] Camera two Camera two – So why does that matter? Well, we're 100% transparent, open source, and fully auditable

Hey Adbank, do we say how much we charge? – [Adbank] Yep, it's on the blockchain – What about you middle man? – [Middleman] I won't tell you (grunts) – Why does transparency matter? Fraud fraud, fraud, fraud 56% of all website traffic is bots 56%! That's over half That means right now you're paying for pants, but you're getting pant Stop getting pant robbed

Get both pant legs now And we're gonna do it How? Artificial intelligence plus the blockchain allows us to differentiate between bots and genuine people Cool, right? That means with Adbank you can stop paying to show your ads to these guys and start showing them to these guys – Hi

Do you accept lots of cash? – Plus we're Canadian so we're stopping fraudsters without ever raising our voice Yeah, I caught you Sorry – Sorry – So if you like having more cash, and you don't like being defrauded, and you want to know exactly where your money is going then voila

Adbank And you can trust me 'cause my name means wise centaur Okay now that matters (dance music) – [Director] Alright cut Good job everyone

How does a blockchain work – Simply Explained

Blockchains are incredibly popular nowadays But what is a blockchain? How do they work, what problems do they solve and how can they be used? Like the name indicates, a blockchain is a chain of blocks that contains information

This technique was originally described in 1991 by a group of researchers and was originally intended to timestamp digital documents so that it’s not possible to backdate them or to tamper with them Almost like a notary However it went by mostly unused until it was adapted by Satoshi Nakamoto in 2009 to create the digital cryptocurrency Bitcoin A blockchain is a distributed ledger that is completely open to anyone They have an interesting property: once some data has been recorded inside a blockchain, it becomes very difficult to change it

So how does that work? Well, let’s take a closer look at a block Each block contains some data, the hash of the block and the hash of the previous block The data that is stored inside a block depends on the type of blockchain The Bitcoin blockchain for example stores the details about a transaction in here, such as the sender, receiver and amount of coins A block also has a hash

You can compare a hash to a fingerprint It identifies a block and all of its contents and it's always unique, just as a fingerprint Once a block is created, it’s hash is being calculated Changing something inside the block will cause the hash to change So in other words: hashes are very useful when you want to detect changes to blocks

If the fingerprint of a block changes, it no longer is the same block The third element inside each block is the hash of the previous block This effectively creates a chain of blocks and it’s this technique that makes a blockchain so secure Let's take an example Here we have a chain of 3 blocks

As you can see, each block has a hash and the hash of the previous block So block number 3 points to block number 2 and number 2 points to number 1 Now the first block is a bit special, it cannot point to previous blocks because it's the first one We call this the genesis block Now let's say that you tamper with the second block

This causes the hash of the block to change as well In turn that will make block 3 and all following blocks invalid because they no longer store a valid hash of the previous block So changing a single block will make all following blocks invalid But using hashes is not enough to prevent tampering Computers these days are very fast and can calculate hundreds of thousands of hashes per second

You could effectively tamper with a block and recalculate all the hashes of other blocks to make your blockchain valid again So to mitigate this, blockchains have something called proof-of-work It's a mechanism that slows down the creation of new blocks In Bitcoins case: it takes about 10 minutes to calculate the required proof-of-work and add a new block to the chain This mechanism makes it very hard to tamper with the blocks, because if you tamper with 1 block, you'll need to recalculate the proof-of-work for all the following blocks

So the security of a blockchain comes from its creative use of hashing and the proof-of-work mechanism But there is one more way that blockchains secure themselves and that's by being distributed Instead of using a central entity to manage the chain, blockchains use a peer-to-peer network and anyone is allowed to join When someone joins this network, he gets the full copy of the blockchain The node can use this to verify that everything is still in order

Now let's see what happens when someone creates a new block That new block is send to everyone on the network Each node then verifies the block to make sure that it hasn't been tampered with If everything checks out, each node adds this block to their own blockchain All the nodes in this network create consensus

They agree about what blocks are valid and which aren't Blocks that are tampered with will be rejected by other nodes in the network So to successfully tamper with a blockchain you'll need to tamper with all blocks on the chain, redo the proof-of-work for each block and take control of more than 50% of the peer-to-peer network Only then will your tampered block become accepted by everyone else This is almost impossible to do! Blockchains are also constantly evolving

One of the more recent developments is the creation of smart contracts These contracts are simple programs that are stored on the blockchain and can be used to automatically exchange coins based on certain conditions More on smart contracts in a later video The creation of blockchain technology peaked a lot of people’s interest Soon, others realized that the technology could be used for other things like storing medical records, creating a digital notary or even collecting taxes

So now you know what a blockchain is, how it works on basic level and what problems it solves Want to learn how you can implement a simple blockchain with Javascript? Then checkout this video here And as always: thank you very much for watching

Blockchain verstehen – Vergleich mit Wikipedia (By PFG Debates)

So what is actually these so-called block chain? Difficult to explain, I read it from time: What we should remind ourselves first time, is that the block chain contains so-called lists, called the man "blocks" and in these blocks, the individual data are stored and transmitted for each transaction

This data may be possible everything For example: Transaction data such places and time Sounds pretty complicated – it's too! One can get a better idea in a different way: The analogy to understand that helps us block chain is Wikipedia If we look at Wikipedia, then data is stored there, in the sense of information and images that are transparent understandable for each person

I can go into the discussion Department of Wikipedia and can see WHO, WHAT, WHEN has changed This is obviously a great advantage for example to detect fraud It is similar in Block Chain: If I change things in the block chain, so the block new contains information, it is sent to all, that is: Following I know exactly WHAT WAS participants has changed Nevertheless, the data are anonymous, that is, I do not know which person what has changed exactly just as I do not know which user has transmitted the data Again, the parallel work

Similar to Wikipedia is also at block chain to an infrastructure which is made available So how can I have very different Wikipedias, you can also block chain applications create for very different scenarios We see this in Bitcoins but also in ride sharing services where block chain is used An interesting start-up can be found in Israel: Here is a ridesharing service block chain has used for themselves by allowing people certain "tokens" that is, their own currency, to advocate redeem them for a free ride

The ride is not quite free of course: The people deserve this token by itself offer rides So if I take a 10 km individual, I get 10 tokens and then this per kilometer, because I mitfahre for someone to use itself Quite convenient and quite safe! Similar to Wikipedia, entirely different data In wikis they are just

images and text At block chain may be all that: for example, sensor data of products in the logistics to be transported back and forth Or may be amounts of money crypto currencies

This can be a certificate that can be a certificate I can actually save anything in the block chain, which of course is quite practical That's why it but is so difficult to imagine what will be the future of the block Chain because we do not know which application examples will prevail The analogy with Wikipedia ends when we look at ourselves the issue of security

If you change something in a wiki, you can indeed see who has changed something The Administrators are the ultimate gatekeepers, they can undo changes and there are in doubt quarrels and disputes on the network Unlike in the block chain: This works locally If data is changed, this changed block is transmitted to all the network and it can not be changed later

new transactions Although it can be made, but these can not be changed later Plus: The cryptographic encryption makes the whole thing very secure against attacks That's why the technology has some advantages over Wikipedia you're interested in other topics, then you are welcome to look at our channel We have produced other videos

For example, if block chain is changed, the financial sector or not Just check out! We would be happy if you join us Many Thanks

Blockchain in der Logistik – Kommt die Revolution? (Pro und Contra)

If you believe the speakers at this year's Logistics Congress of the BVL then the logistics industry is already in the digital paradise

That is not the case, you see when you look in practice 60 percent of invoices are sent in paper form through the world This is not only expensive and time-consuming but also prone to counterfeiting The business models of many carriers still rely on analog lack of transparency to focus on digital progress instead We at PFG many customers have currently dealing with the issue of block chain Which themselves use and experiment That's why we thought we'd ask the question: "Can block Chain guide the logistics industry in the digital stone age? Or not?" The revolt of the consumer in the long term transport the block chain in the logistics industry

We see more and more that people attach importance to emphasize that within the supply chain is sustainable mismanaged, but also people are not exploited Secondly, the issue of health and food safety is an important factor The fipronil scandal was problematic for many consumers, and the pressure on companies increases The problem with the status quo: companies often do not know which sources have their suppliers and where they source their products The suppliers put often worth it, that it is not transparent so that prices can be kept as high as possible A solution might be smart Contracts based on block chains As I detail in "blocks" documenting WHERE, WHEN WHAT comes from

That means I can always prove my end customers that everything is set up on a clean supply chain In contrast, of course, is speaking the current working practices in the logistics sector Many suppliers have business models that are based on that they are transparent We do not know exactly where they relate the goods Good for suppliers: These can then turn up the price because they can always say: "It cost a bit more, took a bit longer" Block chain would make the radically transparent The greatest problem with the status quo that many processes occur still analog in the logistics industry Block Chain is a technology based on digitization to setup can only block Chains apply

if the processes are displayed digitally This is a problem that has to be made up On the other hand, it is of course a major cost item for companies

You can save lots of money by employing block chain Firstly intermediaries can be easily edited, which of course looking for intermediaries not good, but for everyone else, as the price then falls On the other hand costs can be saved by the data center will not be centralized are managed, which of course saves a lot of money in staff and equipment

Data will be stored locally in the future of the block chain I think we should not forget: One can by connecting block chain with IOT, reduce delays, by analyzing where the goods are just who they just

All this is also about smart Contracts and the block chain technology What we must not forget, and that's final contra-argument: Especially for many producers there are entry barriers If we look at ourselves, the logistics industry, we see that many products are sourced from Third World countries and emerging markets While it is easy when you upload photos of products and production facilities in the block chain, So in a block which is then transmitted further Nevertheless missing in these countries are often the basic understanding of how digital processes work And often lack infrastructure such as Internet connection or simply the knowledge

how to use the technology properly Knowledge is unfortunately often absent In my estimation block chain is therefore particularly the industrialized nations employ in the coming years, are where digitized, they can also use the technology If you want to join in the discussion and you still interested, then comes Just to our Webinar on 11/20/17 once at 1100 and 1400 We listen to the experts Mr Soysal on block chain

He knows a good and you can ask him your questions Thank you very much for your attention Until next time!
