What is BLOCKCHAIN? The best explanation of blockchain technology

2698 ratings | 153610 views
Blockchain explained in plain English Understanding how blockchain works and identifying myths about its powers are the first steps to developing blockchain technologies. Blockchain is an algorithm and distributed data structure for managing electronic cash without a central administrator among people who know nothing about one another. Originally designed for the crypto-currency Bitcoin, the blockchain architecture was driven by a radical rejection of at (government-guaranteed) money and bank-controlled payments. Blockchain is a special instance of Distributed Ledger Technologies (DLTs), almost all of which have emerged in Bitcoin's wake. HOW DOES BLOCKCHAIN WORK? Blockchain is a Distributed Ledger Technology (DLT) that was invented to support the Bitcoin cryptocurrency. Bitcoin was motivated by an extreme rejection of government-guaranteed money and bank-controlled payments. The developer of Bitcoin, Satoshi Nakamoto envisioned people spending money without friction, intermediaries, regulation or the need to know or trust other parties. Technically, the original blockchain is separable from Bitcoin, but this report will show that the blockchain design is so specific to Bitcoin that it's not a good fit for much else. The central problem in electronic cash is Double Spend. Because pure electronic money is just data, nothing stops a currency holder from trying to spend it twice. Blockchain solves the Double Spend problem without a digital reserve fund or similar form of umpire. Blockchain monitors and verifies Bitcoin transactions by calling upon a decentralized network of volunteer-run nodes to, in effect, vote on the order in which transactions occur. The network's algorithm ensures that each transaction is unique.

Doubt : If the land which stays disputed between Anne and her brother dates back to 1900s and if it has entries dating back to 100+ years, Is there not a possibility that the data entered to the BC in the first place itself could be tampered. For instance, if the data was tampered in say 1970s , then while converting the series of information into blocks, the data that is entered could be tampered one , isnt it ? I have this doubt whenever I read about BC, can someone please guide ?

Doestn the hybrid method defeats completely the blockchain purpose? if only some selected few can change the data without the authorization of the net the inherit trust is completely undermined... yes, sure "their" system would not permit it, but since they have access to everyone who creates the blocks they can change the information at will, am I misunderstanding something?

The bigger the front the bigger the back. Like so many ideas, everything sounds great until you inject the human elements of greed, power, and corruption. That which is created cannot protect against the vices of the creator. Continued digitalization of everything also results in decreasing security of everything. Think how unsafe online voting is....no paper trail = manipulation. Now multiply that by a very large number. So many ways and levels to infiltrate and subvert this. Once you strip away all the mumbo jumbo it becomes clear where this is all going....centralized control. The wet dream of the globalists.....

Most overhyped technology. If i own a bitcoin and lose my private key or somebody steals my private key its gone forever. With my $$/bank account/credit card i dont care about these things. Blockchain tech where you are the only party controlling private keys actually makes things much worse,all it takes to lose private keys and its all gone forever. It happened to a lot of people who lost tons of BTC, bc of this it will never go mainstream Same goes for land titles, car proof of ownership etc centralised gov agency is needed in case you lose access and need to ID yourself. Regulated 3rd party is the best way
NvZ (12 days ago)
that is why they will replace bitcoin with RFID chip. they will use media to incite fear in people that hackers can and will take over their identity unless they get the RFID. bitcoin is only laying the foundations, digitally and mentally, for the Banking Elite. if you have assumed that the Elite have your best intentions at heart, you need to study up on some actual (non gov. propagandised history)

Is blockchain powers have the ability to make people become blind? Bitcoin has no foundation of where the "money" came from. What about the other 100s that are savvy enough to jump aboard the suicide train before it crashes. Would you willingly give me your real money for my make believe computer money? Am I stupid enough to give you real dollar change for 1 bitcoin? Everyone in this pyramid scheme has to con the next person thru the guise of greed that they will become rich. Which may be true depending how long it takes before the people that this is a house of cards waiting to tumble down.

The people who own bitcoins....do they have an ATM card to withdraw real cash? Who gets to audit the system? Where is the real money that went into the "blockchain" to validate the cryptocurrency's worth?
NvZ (12 days ago)
only the Banking Elite will have control to audit. this system removes the human side out of the system - they say it is to remove human error - but it is to remove any ability to hold them responsible for their actions and decisions.

I'm always suspicious when any company has to spend money creating (or inventing) an independent entity, call it a center, an institute, an association, a platform.... to make all of us see how simple, trustable, decentralized, controlled and verified they are. And I get even more suspicious when they have to spend even more money on hiring a publicity agency which then hires writers, director, graphics designers and an actress with a calming, soft voice that appeals to our trusting feelings (with all that crap of unconcious calming effects of mothers voices). All those spends make me distrust. Someone paid for the making of this video. I don't know who, where that money came from and why was spent on this. And I don't know what's the expected reward on that investment. Whether my personal data, my money or both. I guess both.

But you're right the quality of that video and the work involved kinda give us the feeling that there's something fishy behind it.

Tell me if fraudulent entries are entered into blockchain who is there to disprove the info uploaded? Soon this false information is deemed true. What happens when the original data is destroyed to cover up the false entry? And if no one is overseeing the data and the real paper trail is destroyed the creator of the computer data is now the greatest thief. Idiots believing in a computer system where hackers are making billion every year. Why can't they stop even a handful of these criminals? Now you are going to let the crooks rule over all things of value?

Actually, you need to have trillion dollars of worth equipment to alter the blockchain. Because it is secured with the most powerful computer on earth which is distributed over continents and countries. And value for money? If your government pay your salary with a paper and say hey u can use this to buy tomatoes you believe (or have to believe) it right? So people believe that they can buy something with Bitcoin. This makes it valuable :D
redhotsun51 (6 days ago)
Its not stored on just one PC or server. Every change to the information is recorded and synchronised across the network, it's transparent for all parties to see. If Jack changes something in the contract that change will be visible to all parties including Jill in real-time. You can't fake a mathematical crytographic sequence, it's either black or white not both. All nodes store the same information, it's mirrored. It's similar to the original idea behind the internet (ARPA-Net) which was designed to withstand a nuclear attack. If one part of the network was destroyed the other nodes would continue to communicate in a mesh thus allowing a retaliation from another silo. The data can't be manipulated.

Harshit Agrawal (24 days ago)
There are a few doubts I have. Firstly, companies have large servers to store their data. They need large servers because there is so much data which needs to be stored. Now with blockchain each node, ie, each computer would need to store all of that data. Where would be they this large storage space? Secondly, for blockchain to be immutable, the number of nodes in the network must be large. Otherwise all the involved nodes can be hacked or could even be destroyed, thus destroying the entire blockchain claim of immutability. With the growing number of firms implementing their block chain networks, the problems should only become confounded. It maybe that I don't understand it completely or there are provisions to solve these problems already.
Praveen Shahi (1 hour ago)
Hey Harshit, Genuine Question. I can try to give you some perspective regarding what you asked but not the whole thing since it would confuse you with details. Firstly, As you asked about large storage space. It doesn't work like the conventional system. Each node in the blockchain works as a ledger itself, i.e. it holds the data of transaction, for example, Bitcoin as an implementation of blockchain is famous majorly cause of it's decentralized nature. The advantage of this decentralized nature is huge bro, simply cause even if you had the best supercomputers available, you won;t be able to 'HASH' out bitcoin addresses, simply cause it requires 'huge' amount of processing power to reach that specific Hashrate, (that's the mining part am touching here, which has multiple algorithms). So one doesn't need storage space to hold the entry of ledgers, but one would need huge computational power to gain control of the blockchain or to create new blocks. Secondly, Even if I have 10 nodes in the blockchain, to reach to the 11th block itself, requires high amount of processing power, thats the beauty of blockchain, Yes you are right in saying that it becomes better with an increase in the participants, But even if someone gains the control of a blockchain with less nodes, they can't derive any value from it, since it would cost them huge to create further nodes and blocks. Why do you think people gained absurd amount of bitcoins when they were mining in the initial days (read abt the most expensive pizza). Lastly, what you touched upon the increase in the number of companies adopting blockchain, it won;t make the problem more complex cause firstly, blockahin is more like 'JANLOKPAL' , i don't know if you get the reference here, but the power to create and control is in the hands of the participants, that's the catch that makes it the tech of future. This goes way deeper than mentioned in the video but the vid is for the intro part of blockchain only.
Yusuf Özen (2 days ago)
if u want to store all the transaction data since the beginning of bitcoin it is now about 200gb. Nothing impossible to store. But if u ask using a wallet app from the phone, that data still not be manageable. So you don't need to store all data to validate your transactions. Instead, a procedure called Simple Payment Verification (SPV) occurs by ur wallet to validate. That works by getting only info associated with your wallet, not the whole peoples' info in the world.
TheBiban12 (10 days ago)
From Satoshi's white papper about Bitcoin "A block header with no transactions would be about 80 bytes. If we suppose blocks are generated every 10 minutes, 80 bytes * 6 * 24 * 365 = 4.2MB per year. With computer systems typically selling with 2GB of RAM as of 2008, and Moore's Law predicting current growth of 1.2GB per year, storage should not be a problem even if the block headers must be kept in memory"
Joe SGBKU (15 days ago)
Google peer to peer and read it in depth. It will answer your first question. Actually, you should probably just read about blockchain again because I think your questions show you're missing the basics. Just wondering, did you study computer science or anything tech related?
Virat Khanna. (16 days ago)
Harshit Agrawal You know what kinda people can't stand criticism and questioning their beliefs. Such people don't understand that debates and criticism actually helps to detect and eliminate any possible flaws in any system. And anyone who has worked in the programming, coding, systems/product development, management or in operations appreciates and understands the value of criticism and questioning because they know how it can help the process. But this guy clearly loves getting triggered and telling people how great he is in that field instead of sharing what he thinks. Anyways I like the fact that you had questions instead of just following a trend and who knows one day someone might end up resolving these issue making this a really reliable system as they claim it to be. Peace.
Austin Kelly (25 days ago)
Honestly it’s just the internet made more complex and being sold as a more secure data storage system to companies.
tellyaddict3 (11 days ago)
Austin Kelly That's not it. The princples behind this technology are not that complex actually, it's just a new application made possible by a large network like the internet. You could have a single copy of a blockchain on your pc but then it's no use to the rest of us because it's just your own private database. By having everybody have a copy and synchronizing over the internet then it becomes useful because through the block hashes it can be ascertained that there is no tampering going on and thus consensus is maintained. See this vid, it really helped me a lot: https://www.youtube.com/watch?v=SSo_EIwHSd4 Also note that Bitcoin was not created for companies but in reaction to the banks and the financial crisis that they brought about. It is truly the currency of the people, not the banks or any government.

In marketing your "attention" is currency. Now, in this financial revolution your "data" is the currency.

Excellent video, this ours future and even already real. The cryptoworld promptly develops and has big prospects. The generosity and prospects at height was fond of the TokenGo platform. Investors increase that speaks about success of the project. I wish all success become a part us.

5:10 "It could allow everyone to view property records, but reserve to itself the exclusive right to update them." In this scenario, why would a blockchain be used instead of a single, central ledger that people have "read-only" access to?

I get what you're saying but this hybrid model wouldn't run on proof of work like bitcoin. So then the blockchain is purposely coded so that the company isn't able to do that through this hybrid method. Problem solved. The company isn't taking control of the blockchain in this hybrid model, they have only been given the ability to make changes, transparent, immutable audit-friendly changes.

rean247 thing is, if its a private sistem where the company controls all the nodes, they can basically change the whole blockchain and just place those other “normal” blocks on top.
rean247 (30 days ago)
No everyone would be able to see that the company changed the information because a new block would be added, instead of the company being able to edit the fine print in secret. That's what makes it immutable. People will trust the company/system more.

Thanks for this. I like the explanation at 289 seconds in. Did you know that that granular data access model is the actual foundation of everything Lotus Notes does? It is the very basis of IBM Lotus Notes Forms and the Security Model which has been in use for almost 40 years.

How to become bitcoin trader? Exactly like Bitcoin, multiple digital currencies exist in the marketplace. So if you prefer to buy a few other currencies which aren`t available on Indian Exchange than you can utilize Bittrex. All you have to do is locate an exchange that you favor. Cryptocurrency exchanges have a massive potential to modify peoples minds and opinions concerning cryptocurrencies generally speaking and their application in actual life. So even in the event the exchange is attacked, its still true that you have your money. Furthermore, the exchanges prepare each and every industry for Bitcoin expansion. Existing stock exchanges will also compete to be able to fulfill the users configuration requirements. Sooner or later later on, the prices will grow more equal, meeting somewhere in the middleyour profit is equivalent to the quantity of convergence. No matter how far it is from Kijun, it is likely to return and test that level at some point. The amount of bitcoin is perpetually changing. In the US, it is 1000 USD. Whats even better, seek the services of a seasoned lawyer or at least ask for an in depth consultation. So youve read the newspaper about the meteoric growth of crypto currencies including Bitcoin or Ripple. Then coming up with 1000s of exchange rates simply to go out and get groceries is nearly impossible. Many cities around the world provide a bitcoin ATM where you are able to trade cash for bitcoin. The cryptocurrency world isn`t efficient.
