How will you explain blockchain concept to a non techie

Hope this simple explain, could help you to explain the others.

Blockchain is one technology that does not use third parties in the data exchange process or in the transaction process.
as like if you buy something in the store by using a debit card, the third parties here are banks that connecting the buyers and sellers in the transaction using the debit card. But in the bitcoin, seller and buyer can be directly connected without third parties assistance.

In addition, because of this, the term "decentralized" can be paired with it, since no one owns and controlls the system. Other than decentralized, it's transparency is also one of its main characteristics to look at, every transaction made can be seen and tracked with blockchain. But the thing is, it's still anonymous so it's kind of contradicting.

That's easy. You suggest he reads the threads on Bitcoin Talk. :)

There are several explanatory video's on the web. Sometimes it's easer to understand things when they are visualized.
Maybe you should try this one: https://youtu.be/SSo_EIwHSd4 It is pretty understandable.
Also: Use a lot of different sources to learn from. Don't watch one video and believe you got it.

I would read something on medium as well as watch video explanations. But don't just watch videos as it is too passive. Try and explain it to someone after to see if they get it and if you can explain it you've understood it.

Can't explain this on a brief explanation.

What I've heard before which was the briefest, it's a record of transactions that everyone can see but it can't be manipulated nor modified. But if this isn't counted, go on with the suggestion of others. Read those threads and videos that can explain it to non techie in the easiest way.

Blockchain is best known as the technology behind the cryptocurrency bitcoin -- a digital currency whose value soared above $19,000 over the last year before slumping to half that when the frenzy subside.

Go to this website: (https://www.weforum.org/agenda/2016/06/blockchain-explained-simply/).
There's a video embedded, please watch that 2 minute clip that could help you and your friend understand the concept behind Blockchain Technology.

LOL, you should find out in forums and websites to find out about it better than here and ask that question. Blockchain, which is a database system of information, is used to store information in linked blocks and is managed by all participants in the system, instead of one. a separate third party such as the state or the central bank; It also allows for secure data transmission with a complex encryption system and is scalable over time.

All data on the Internet is easily copied. As we know, Bitcoin is just one application of Blockchain technology, meaning that each Bitcoin transaction is just one file.
Normally, when dealing online, we will need a third party that we trust (eg, intermediary, shipping company, bank ...) with a database set to verify the transaction to prevent fraud when the crooks use this file repeatedly.
Blockchain technology solves this problem without the need for a reliable third party.

I'll try to explain better than the others.

In many cases/applications the data is saved into a database. Just imagine it like a notebook.
Now, in most databases you can write onto any page. In blockchain every time you write you add a full page at the end of that notebook.

This fact makes feasible to keep copies of this database/notebook on many computers around the world - keep it decentralized -, since at sync (whenever the wallet is started or a new block was found) just the missing pages at the end have to be added to the "notebook" (on a certain computer).

And yes, a "block" in the "chain" is such a "page" in the "notebook".

In a nutshell, Blockchain possesses a very special feature: the transmission of data does not require an intermediary to confirm the information. The Blockchain system has many independent nodes that can authenticate information without requiring a "sign of trust". The information in Blockchain cannot be changed and only be added with the consent of all nodes in the system. This is a high-security system against the possibility of data theft. Even if part of the Blockchain system collapses, the computers and other nodes will continue to protect the information and keep the network going.

Imagine a digital medical history: every record is a block. This entry has a label: the date and time of the entry. Initially, it is considered mandatory to prohibit the modification of records hindsight, because it is necessary that records of diagnosis, treatment, etc. They did not allow different interpretations and remained in the original form. Only a doctor who has one private key and a patient who has another one can access the records. Then, access this information only to those who have one of these users to obtain a private key (for example, the hospital as a whole or a separate specialist). Thus, for example, blocking technology can be used in a medical database.

The easiest way to think about Blockchain is to imagine it as a hierarchical database that stores information in blocks of information that are interconnected by encryption and expanding over time. Each information block contains information about the time it was created and linked to the previous block, including a time code and transaction data. It's like a ledger.
But the special feature of Blockchain is that this database is distributed decentralized on the internet. That means that this database is spread around the world, owned by all computers in the peer network.
There is no central server hosting this database, no one has control over this database. Once the data is written to this ledger, no one can delete it, or change it. It cannot be hacked. Blockchain helps participants reach consensus on information without going through a third party.
You should find out more in the forums and the site for a good understanding!

Briefly, Blockchain, the root name of a blockchain, is a hierarchical database that stores information in blocks of information that are interconnected by encryption and expands over time. Each block of information contains information about the time it was created and associated with the previous block, including timecode and transaction data. The blockchain is designed to resist the change of data: Once the data has been accepted by the network, there is no way to change it.

I usually only explain a few words with them.
The blockchain is a public account book that people all over the world can see and use over the Internet, but cannot change it!

Based on my understanding, Blockchain is a hidden transaction or should I say Privacy when you want to not trace who you are.

Blockchain technology can be said to be a combination of the three technologies below:
Encryption: Use the public key and hash function to ensure transparency, integrity, and privacy.
Peer-to-Peer Network: Each node in the network is considered a client and also a server for storing application replicas.
Game theory: All nodes involved in the system must comply with the rules of consensus (PoW, PoS ...) and motivated by economic incentives.

Bitcoin is just like a bank account, but the difference is that you don't need to go to a bank and open account there to receive your IBAN. You can just use an Bitcoin address generator to create your Bitcoin IBAN which is called address. Also, when you generate your address you will receive a password so you can manage your balance which is called private key.
Bitcoin advantages:
- accepted worldwide, no bank restrictions
- you can spend or receive money during weekends and non-working hours
- no KYC/AML
- anonymous
- you trust maths, not banks
- Much cheaper for huge transactions. if you want to transfer $1mln or more worth of Bitcoin the fee will be around 1$ or less. If you try to transfer $1mln from 1 bank to another, you will get a fee of 1-5% which is 10-50k fee.

Blockchain is a digitized, decentralized, and the public ledger of all cryptocurrency transactions. It is constantly growing as "completed" blocks; usually the most recent transactions are put down and added to it in a chronological order. It gives authorizations to market participants to monitor digital currency transactions without central record keeping.  Every computer connected to the network gets a copy of the blockchain, and by default it downloads the copy automatically.

Blockchain is not bitcoin. Blockchain is just the main technological innovation of bitcoin, same as with other cryptocurrencies.

And ask questions afterwards if he/she did not fully understand what blockchain is to clarify his/her questions about blockchain to the pro out there.

Blockchain is a network that is supported by users that mine tokens, without any servers. When all coins will be mined, as I see, the network won't work.
