Do me a favor, tell me really clearly and slowly what exactly a blockchain is?

Blockchain is a digital technology that allows you to safely store and use large databases with various information using the Internet on-line. Based on the fact that it is absolutely safe to store and use such information with the possibility of public access to it, very good prospects open for using this information technology in various areas of our lives.

Well not meant to advertise but the one im using Okex they  has a knowledge base, go visit ! https://blog.okex.com/

Simply just admit to your boss that you don't have any idea on blockchain or else you will be like in a hell workplace.

In simple term, Blockchain is just like a ledger where all transactions are being recorded.
Every block contains data of transaction which is being listed on the blockchain. There is other definition on it which is more elaborate but complicated.
I suggest to use Google or Youtube because there is a lot of useful explanation out there which I myself used during my newbie days.

You said "cheated"?

Well well, even if you manage to pass this test, I doubt you'll last in your position if you don't figure it out by yourself. Instead of cheating to get a job, you better increase your skill and run another interview (no cheat at all).

[bitzizzix]

You have to admit if you don't understand or you can't answer it and it will look professional or you answer to try to find information and learn about the blockchain, as soon as possible if needed.
and you can find information widely and clearly through Google or Youtube.

Blockchain is digital technology
or large digital books based on decentralization and distributed publicly through online internet that functions to record or record transactions on many computers so that records cannot be changed retroactively without changing the next block or consensus on the network.

Blockchain is a technology that involves running in a decentralized mesh of network that makes blocks (from the word itself, blocks in a chain). These blocks can handle sensitive data, such as transactions, files, or anything you can think of that can be transcribed digitally. Also, each blocks contain a pointer to its previous block through hash (result of a function based on the data inside). This means that any change within a block would change its hash value, and would disrupt the network. That's why there are nodes (computers that use computational power) that validate these data inside and make sure of the integrity of the chain. Since there are many nodes connected and validating incoming data, more than 50% of the whole network nodes should validate and agree to every new block created, so any attempt to alteration should have access to >50% of the nodes, which is near impossible.

Yikes mate. Impressive you got your way through the job interview, but if I may give some advice, it's just going to end up worse and worse for you if you don't know what to write about.

Go read a lot of articles, if you want any chance of all at keeping your job, otherwise, I wish you good luck for future job interviews, because with this mindset it'll be very hard to keep one.

I'll help out, here are some informative videos

The simple way to explain this is that it is a chain of transactions that are added to a decentralized database. In the Banking system the Bank use a centralized <private> database/ledger that only they can access to record all the transactions that are done by their customers, but in Bitcoin you do not have a centralized database that are managed by a single entity.

So Satoshi Nakamoto wrote a protocol <software> that enables 1000s of people to store a decentralized <ledger> of all transactions that are done with the Bitcoin tokens and this is recorded on the Blockchain. <It is basically immutable, because nobody can change anything, once it is added to the Blockchain.... well without them deciding as a collective to rollback.>  

[MURONDI]

that is a common question that crypto users should understand, Blockchain is a system of recording transactions in many databases that are widespread on many computers, With this decentralized transaction record, it is almost impossible to change unilaterally, without changing the majority of all databases.

Here is my one of my favorite explanations of Blockchain and Bitcoin: http://jrruethe.github.io/blog/2015/04/26/bitcoin-analogy
It is in analogy

Back then as newbie I was able to understand Blockchain easily with the analogy.
I remember reading somewhere that not everyone understands things explained in metaphor. Hope it makes sense to you.

Lol, you cheated your way thru a job interview got the job and now you wanted people here to help you out? Why not used the big G to help you, and search everything about what blockchain technology is. I must tell you that you will be overwhelm with the explanations given to you by different members here so it's better if you do your own research about it, just saying.

Cheating doesn't give you any good results, so it's best to stop by and learn about blockchain first and how it's used.

If you pass that, your work will still not be good because you will not be able to do the content because you have zero knowledge about what blockhain is.

You are in for a lot of research for that kind of job. Trust me, I'm speaking from experience. As for your question, blockchain is a distributed, decentralized ledger that can store huge amounts of information, such as cryptocurrency transactions. The information is packed into groups called blocks, which are recorded and stored chronologically. There are private and public blockchains, where public ones are available for anyone to inspect, and private ones require permission to access. All data stored on the blockchain is immutable, and the only way to change anything is to have the community that runs it to agree to change it simply by adding new information, that overwrites the old one. This makes it impossible to hack, as you would have to hack more than half of the network members, who are located all over the world. Basically, it is as secure as it can be. There is also the issue of mining, which is the process of solving blocks and verifying transactions, which is what crypto miners do. In return, they get rewarded with a certain amount of coins. This is all very basic and something that any article could tell you. The best way to move forward is to do your own research, which will be a lot of reading.

Point well made, OP is literally in a bad situation right now but guess what? its his/her choice at the first place. You know what someone lose the opportunity because of that, maybe they are much more deserving than you but now you are suffering the consequences of your actions. Well its better if you find out things on your own, because in that way you will easily understand things. You can't just depend on people's opinion and thoughts about blockchain, you need to have your own exploration.

[HighRed]

Put really simply, a blockchain is a chain of blocks (duh) where each block consists of several transactions. Each block is connected to the block before it and thus they form a chain. When you calculate all the transaction over all the blocks in a blockchain, you get the balance in each address. You can't change a block in between and re-insert it to the chain because each block is connected to the previous block. And you can't just add funds to yourself because the system is decentralized, which means everyone who has a node has a say over what next block will be, and the longest blockchain is usually the approved one. So trying to trick the system won't work unless you have the ownership of over the half the nodes. There are all kinds of methods on how to confirm if a block or a blockchain is valid, such as proof of work and proof of stake (simply put, calculating/guessing the number that decrypts the block), and changing the difficulty of this confirmation process sets the time required to decrypt/mine a block. Too low and the system becomes less secure, too much and the system stops working.

There are tons of videos on Youtube and other platforms that you can watch. I believe others have already linked a few.

Good luck and hope you don't get fired. Don't cheat next time

These will depend on his task deadline, if he think he can still certify his position and have time to studied blockchain overnight then he can continue it and act as if he's not cheating. He can create details as newbie but maybe not the way the boss expected it on him. We know the opportunity is there but if it will make you suffer from the rest of your stay in that company since you lied to them better tell them the truth or work hard to be like "what they expect you to be, like what your cheat submission, your call"

Cheating won't help an individual to grow; However, learning will never stop.
He passed the job, then it's his responsibility now to prove that he can do the job by learning everything he needs to know about it.

Learning takes time depends on an individual understanding. If he believes in himself that he can do it before the said deadline, then he may cover his cheating activity. If he did it, then he can secure his position on the job.
He can't provide a deeper explanation for now and it's the consequence of cheating, but after having a research and he still remains the same, his job will be out of his reach.

You are cheated because you are pretending that knowledgeable on your job but the truth you did not know what it is. Instead of relying upon people's opinions here why not just research your own. There's google and youtube for the video presentation about blockchain and how it is work if you use this system. As friendly advice just research this your own.

Here is the simple explanation, https://en.wikipedia.org/wiki/Blockchain.

[Genemind]

You should have told your boss the truth because he will still notice the truth despite having the definition of it. You can define Blockchain through the searching and asking but learning about it will take time and it will be a long process. Just don't cheat next time because that could lead you into mess and mistakes in the future. It's still better to be honest and accept that you know nothing about a certain thing.

take your time to open and read a little explanation about Blockchain technology here https://en.wikipedia.org/wiki/Blockchain.

and also a broader explanation of Blockchain technology here https://www.investopedia.com/terms/b/blockchain.asp.  

Blockchain technology is the technology that is being looked at by world leaders, Blockchain technology is the future.
