How do we help kids make sense of the crypto world?

Crypto 101 for 9 year olds.

Or 99 year olds.

And every age in between.

🪡
1/ What are cryptocurrencies?

Cryptocurrencies are digital currencies.

They can be used to buy things, but there are no bills or coins.

Bitcoin is the most popular, but there are others like Ethereum, Ripple etc.
2/ How do cryptocurrencies work?

Currencies like the US dollar are controlled by governments and central banks.

Let's use Bitcoin to understand how cryptocurrencies work.

Bitcoin is a form of digital money which operates outside the control of governments.
3/ What's blockchain?

Bitcoin is built on blockchain, a public ledger (a big, electronic exercise book) that records Bitcoin transactions.

Blockchain is made up of a network of computers connected to one another through the internet that all store a copy of the ledger.
4/ What does blockchain do?

Blockchain allows everyone to see everything that happens on the network.

E.g. when mum sends little Julia a Bitcoin, the transaction is saved on every individual computer, so everyone knows little Julia received a Bitcoin from her mum.
5/ How does blockchain prevent cheating?

Everyone on the network keeps a record of every transaction, and everyone has the same copy of the ledger.

All of the users record all of the transactions at the same time.

No one user can manipulate a transaction in any way.
6/ Why do some people prefer cryptocurrencies?

Cryptocurrencies are rule-based and require the consensus of network participants to change.

This protects cryptocurrencies from abuse or manipulation by any one person or central authority
7/ Who determines the value of cryptocurrencies?

Cryptocurrencies can be traded, like stocks and pokemon cards.

Price is determined by demand (how much interest there is to buy) and supply (how much is available).

Rare pokemon cards are expensive because demand > supply.
8/ Why isn't everyone using cryptocurrencies already?

There are too many (> 8,000)!

Bitcoin is the most popular, but the price of Bitcoin goes up and down too fast.
9/ How do I store cryptocurrencies?

You need crypto wallets that are either software (app) or hardware (gadget).

Crypto wallets store two keys.

A public key links to an address that lets you send and receive transactions. Think of it as your email address.
A private key proves that you own the cryptocurrencies associated with your public address. Think of it as your email password.

You can share your public key with others to send and receive transactions.

You must never share your private key.
10/ Anything else I should know?

It takes a lot of electricity to power the computers that maintain cryptocurrencies. Not good for the planet!

Some people think cryptocurrencies are the money of the future. Others think not.

Read up. Question everything. Decide for yourself.
Bonus

Nobel laureate and long time crypto skeptic Paul Krugman recently said this about Bitcoin:

"I’ve given up predicting imminent demise. There always seems to be a new crop of believers. Maybe just think of it as a cult that can survive indefinitely."
Thanks @hey_bernie for working with me on this thread.

h/t @petergyang for the excellent explanation of keys.

10 of Naval’s best ideas that kids can start actioning on today.

Navalism for 9 year olds.

Useful for 99 year olds too.

🪡
1/ “Sharks eat well but live a life surrounded by sharks.”

Bad behaviour hurts others, but most of all it hurts you.

The school bully is usually the one with low self-esteem.

Don’t do things you won’t be proud of.
2/ “You get rewarded by society for giving it what it wants and doesn’t know how to get elsewhere.”

Don’t copy.

Think out of the box.

Be a maverick.

Be street smart.

How Ninja Van built a billion dollar business using First Principles Thinking.

A perspective from their first investor and current board member.

The case for getting kids to learn to reason from first principles and how it benefits them today.

🪡
1/ Incumbent logistics players are not set up to deliver e-commerce parcels.

Traditional logistics: Pick up from one warehouse. Resupply 20 stores once a week.

E-commerce logistics: Pick up from multiple merchants. Deliver parcels to 100 addresses every day.
First principle: classic case of disruptive innovation targeting non consumption.

E-commerce merchants are not (well) served by traditional logistics players.

A startup designed to suit the needs of e-commerce merchants can disrupt incumbents.

Howard Gardner defines intelligence as the ability to solve problems, generate new problems, or create something valuable.

How intelligent are you?

What can school do to develop your child's intelligence?

Let's find out.

🪡
1/ The ability to solve problems that one encounters in real life.

ie. The mental capability to get out of sticky situations.

eg. Apollo 13 crew jury-rigging contraption using sock, duct tape etc to reduce CO2 level.

h/t @vasanthsarathy's article on real world problem-solving
@vasanthsarathy Teaching problem-solving requires letting students get stuck and unstuck.

Teachers need to be adept at helping students come up with strategies to get unstuck.

More importantly, teachers need time to let students work through struggles.

8 emerging K12 edtech startups I hope will take off in a big way in 2022.

If all of these startups are successful, we will see a paradigm shift in how kids learn.

Change in education is long overdue.

Disclosure: I am an investor in a few of them.

🪡
1/ @innovamat_es provides instructional materials that help kids think better, starting with math textbook replacement.

Research from learning science + evidence-based + teacher-focused = changing the textbook game
@innovamat_es 2/ @wearelearnlife is learner-centred and focuses on self-determined, purpose inspired and personal learning.

Got a tour of their school in Barcelona and came away really impressed with the innovative approaches to learning and the autonomy given to learners.

Audience Building and Ship30for30 changed my year.

Want to get 2022 off to a great start?

Join a cohort-based course that resonates.

A thread on how learning online with like-minded folks became my highlight of 2021.

🪡
1/ Audience Building is exactly what I needed to get started on Twitter.

I had been wanting to spend more time on Twitter because so many smart people I know are on it, but I kept procrastinating.

Audience Building is, well, about building your audience on Twitter.
2/ @SahilBloom is a great instructor who is generous with sharing tips and supporting folks on his course.

Learn from folks who were in your shoes not too long ago.

Sahil went from nothing to 200+k followers when I did the course in Sep to 400+k today.

Learn from the best.

Asked a few founders what's the #1 skill they hire for and designed cohort-based courses to help kids 9-15 learn those skills.

This is what we learnt from @DoyobiEdu's first cohort of Founder Skills for Kids.

Hint: kids just want to play

🪡
1/ Kids love @gather_town

Gather Town is a virtual world that allows users to meet and interact using voice and video chat.

Kids love customising their avatars, exploring the island we built for them, and interacting with other kids in a video game like environment.
2/ Kids much prefer interactive activities to listening to the instructor.

How many hours a week do kids spend in school on the receiving end of a teacher talking at them?

Real learning happens when learners are active participants.
