face to face tutorial will be the better way of teachibg him i mean you should show them what it is and how to use that blockchain , dont make it more difficult teach him step by step until he remember all the things you teach.
BTW what is the reason why you want him to teach about blockchain?

A 10-year old boy is probably in his 4th grade already. I suppose a 4th grade pupil can already understand words without the use of colorful drawings and diagrams. Creating a story out of it could probably help in order for him to at least visualize in his imagination what you mean.

So I think I would just compare blockchain to a record book containing millions of pages scattered all over the world in which all transactions are recorded. All these pages are connected because each page contains the content of the other pages. And because of this, nobody can change anything in the book. Nobody can tamper the information in it. Nobody could cheat. Because that would mean roaming all over the world to look for every single page before changing them one by one. That would be impossible.

Wow, I experienced this on spot, though not a 10 years old.

I went to a school to attend for my younger sister's meeting. I met her friends and told me that they are doing an explanation of their assignment but she doesn't know what the other one is amd she knows I knew it. I asked and she told it is Blockchain. I am surprised, not because I don't know but because it is being talked about now in a classroom.

So is your sister in high school?

Is she in college?

Or is she in middle school?

I would like to think a child should get some education on blockchain by high school.

But teaching the kid in the 6th grade might be a good time to start.

Just explain to him that how would he keep record if he lends money to various friends different amounts? He will reply by keeping a book of records. How will your friends verify every input in book as not made fake by you? He will reply, by taking their signatures/thumbprints on each record. Then simply blockchain is like that public ledger in which transactions are recorded and verified for whole world to see

take a chapter of a book and give it a title
reference that title in the next chapter so that you link the chapters together.

now a block is a chapter. it is just lots of information. and the chain is linking of the chapters
hense block chain... (linking blocks of information)
..
now to get more complex. the chapter title is not randomly chosen. its a math/word puzzle by combining all the information of the chapter to create its title
a very simple example is.
if chapter ones title was 'alice slept well' and the story was 'one night alice had a nice dream and woke up refreshed' .. well if you change the information to bob instead of alice. then the title becomes 'bob slept well'

chapter two would include just the 'alice slept well' reference not the whole chapter story, meaning the story in the second chapter would not work if the second chapter talks about alice but someone changed the first chapter to bob.
so by referencing the first chapter in the second chapter means the second chapter makes it harder to change the first chapter without having to also change the next chapter.

and this repeats for each chapter. the more chapters there are the harder it becomes to change the first chapter without it  breaking the story.

...
this then makes it easy to check the story to the chapter titles to make sure its all valid. and also then be able to check friends versions of the book to make sre they have the same edition of the story as you.

making it very quick to know that everyone has read the exact same story

It is actually very easy to explain it to him. You can first tell him how Banks record all transactions on a centralized database and then explain to him that in Bitcoin, there are no Banks to record all transactions that are done by the people using the technology.

Satoshi Nakamoto then created software that can be installed on many users computers all over the world, that will collectively share a copy of all transactions that are done by the people using this technology. This is called the Blockchain, because like in a chain, a group of transactions are grouped together in a Block and then that Block is linked to the previous Block to form a chain of all transactions that were done previously. < This is then called a decentralized technology, because all the data are not stored in one centralized database >

I explained it like this to my kids and they understood the whole concept.

the topic is not about bitcoin
   the topic is not about cryptocurrency

the topic is about blockchain.. blockchains are not just currency stuff.. blockchains is the security framework of data. what data is in a block can be anything. whether its financial, identity, DNS, file name, patent logs, law records.. blockchains can have anything.
so to explain blockchains. its best to just explain blockchains and then as a separate lesson if the kid asks. then talk about more specific examples.

By practice. I think it's the best way a young one could learn how Bitcoin/blockchain works.

Practicing is simple. You buy a very cheap coin (say DOGE) and you help him create a wallet for himself. From that point on, all you have to do is show him how to do transactions and different things like "look, I can see what you're holding in your address! It's public!".

Teaching a young child how blockchain works by explaining it is hard. I'd rather give him and one of his friends/relatives of his age a wallet each with a few DOGE loaded up and let them experiment themselves.

I've personally learned most of my English through Google translate, writing articles and playing video games. I've learned Bitcoin the hard way, without anybody explaining to me what it is and what it can do. You have to go through the worst stuff to learn - we learn the best from mistakes.

Blockchain is very wide and broad topic. For a ten year old kid, that's way above his level. But you can used some way like giving him a picture or diagram that showcase blockchain and how it works in a very easy languages but the meaning is same.

But the era now is changing more kids nowadays are fond of using tech such as mobile phones and even browsing internet right? If they can learn that then they can also learn basics of blockchain. Start from scratch and the process wouldn't be too hard for him. More importantly, have patience with him as teaching kids isnt easy at all. Why do you wanna teach your boy now to so he can start mining and trading already?

[romero121]

I'd get some paper a pencil and a sharpie. Start writing things like I give you 1 dollar, you give me 50 cents and write these in pencil swapping the dollar back and forth then erase it and take the dollar back. Show that someone else has control and can revert deals, now  write in sharpie the deals, say you want to revert one and show how you can't erase the permanent marker and it can't be undone, to get the dollar back a new deal must be written in marker.

Something like that seems easy and use multiple sheets of paper each sheet representing a block.

This will be easily understood by any kid who wish to learn about blockchain. The sheets representing the blocks, and the writing on pencil which is erasable as the traditional banking system and the writings with marker as a permanent data added to the ledger as the blockchain technology based data addition.

[davis196]

You don't have to explain that to a 10 year old boy.10 year old still don't know how bank,fiat money and taxes work.Wait for 3-4 years and then try to explain how the blockchain works.
I have a very oversimplified explanation:The blockchain is just a bunch of servers connected to each other,and every time there's a transaction between person A and person B,all those computers have to confirm the transactions using complex math tasks.Yes,it's oversimplified and kinda wrong,but a 10 year old might get it.

[AicecreaME]

First of, make a promise to him, kids like being rewarded if they do a great job, so I guess buying him a new toy, a PlayStation, or whatever he wanted will suffice for him to a good student. If you are not an expert when it comes to understanding about the whole blockchain thing, you should ready yourself for so many questions, because a kid will surely ask you anything that can't reach by his level of understanding, unless he is a prodigy.

You could also make a lesson plan, like what teachers are doing, the night before they go to school the next day, that is a nice guide for you to teach him the basics to major things about blockchain.

If I want to simply explain to a 10 years boy. what is blockchain? How should I explain? Please give your answer.

I think a jigsaw puzzle would do fine. Just make a single line of it, and notice how you cannot swap the correct pieces with wrong ones, as the line would fall apart and never connect again (chain is broken).

Also notice that to build a solid line you have to connect the correct piece one after the other, which is what a blockchain does.

@Oasisman is right this has been discussed before and i have seen this topic all over the internet though this has some word play to  it

A small ebook about it here : https://www.amazon.com/Place-Blockchain-Brett-Biery-ebook/dp/B07C9TSMCR (I'm not the author and it's not a ref link)

and i'm also writing a text, please wait

Edit : I wrote it in like 15mn so of course it's not enough but that's the spirit :

Once upon a time, in the realm of truth..,
The inhabitants created a book to know in real time how much candy each child had.
The wiser the children were and listened at school, the more candy they received.
The children could ask for and eat these candies at any time.
When a piece of candy was eaten, the book was updated accordingly by a bookkeeper: Mr. Banks.

One day Mr. Banks thought he wanted to eat candy, too.
So he took up his pen and changed some values in the book...

When some children went into the room where the book was, they discovered that the numbers were not the same...

Seeing that Mr. Banks had more candy than before, they went to warn the adults.
The adults reading the book saw no mistake... and didn't believe the children...

Saddened by the loss of their precious candy, they went to the sorcerer of the kingdom that no one had ever seen: Mr. Nakamoto...

After explaining the problem, Mr. Nakamoto summoned the King to set up a new version of the book.

This book, called "Blockchain" was a version identical to the previous one.
However, Mr. Nakamoto announced that the numbers would no longer be written with a pen but with an indelible marker.

The days passed and one morning, Mr. Banks had a sudden craving for candy.
He tried to erase the numbers to change them, but because of the indelible marker he couldn't do so.

So he thought he could tear out some of the pages and replace them with others.
But he hadn't seen that Mr. Nakamoto had bound the pages with a thick golden thread.
No matter how hard he tried, not a single page was torn out.

Faced with this problem, Mr. Banks gave up and it is said that since that day, children have been eating their sweets quietly while contemplating the magic book "Blockchain".

I'll use his toys to explain, assuming he/she has a building materials related toys like building tools, blocks etc I'll leverage on that but if the kid doesn't have I'll get him one immediately or us any available toy that can be used to build as a practice example because kids do learn faster when things are been thought in practical form then theory. And they hardly forget things they practiced.

I'll tell the kid, in the simplest form, a blockchain is a series of block in a chain form where information are been stored openly in can be easily verified. Then I'll used the toy bricks to build a chain of block and ask him if he can verify how many blocks were used in the demonstration and after we must have confirmed the numbers, I'll than build a wall over the chain of blocks I earlier built than pretend I added more block and ask him if he can guess how many blocks were added.

After the kid must have guessed wrong I'll then review to him/her, that I didn't add any blocks to the already existing chain of blocks but since the chain of blocks were been restricted from public view I could manipulate the situation to suit me and that's how a centralized system like the first currency works (probably call the name of the local currency where the kid reside like Dollars or Naira).

Take it easy with my example.

You are Dad or Mom.
Your kid want to buy a candy.
You give your kid a few cents to buy it.
That kid has to go to a grocery to buy it.

The grocery can tell you (Dad or Mom) that kid buys bought how many candy.
If that grocery staff does not tel the truth to you, you don't know what the kid do with a few cent you give him/ her (buying candy or not, and how many candy was bought).

With blockchain, all of that information will be stored globally, and you (as Dad or Mom) can retrieve it easily, without the words from the grocery staff.
