Learn / Lesson 1
A blockchain is a shared record book. Instead of one company or bank keeping the book, many computers around the world each keep a copy, and they all have to agree before anything new is written in.
New entries are grouped into “blocks”. Each block is linked to the one before it, forming a “chain”. Because every copy must match, it is very hard to secretly change an old entry.
It lets people send value to each other without needing a central middleman to keep the records. That is the core idea behind cryptocurrency.
A blockchain is not automatically safe or profitable. It is a tool, and like any tool it can be used well or badly.

1. What is a blockchain, in simple terms?
Many computers each keep a copy of the book, and they all have to agree before anything new is written in.
2. Why is it very hard to secretly change an old entry?
Because every copy must match and the blocks are chained together, a secret change would stand out.
3. Which statement about blockchains is true?
A blockchain is not automatically safe or profitable. It is a tool.
Learn / Lesson 2
Decentralised means no single person, company or government is in charge. Instead, control is spread across many participants who follow the same shared rules.
A bank is centralised. It keeps your records, it decides who can use its services, and it can freeze an account. If its systems go down, you wait.
A decentralised network, like Bitcoin, is run by thousands of computers around the world. No single one can change the rules alone or switch the whole thing off.
There is no customer service desk to reverse a mistake. You are responsible for your own security. Big decisions can also be slow, because many people have to agree.
Some projects are more decentralised than others, and many crypto businesses, like exchanges, are still centralised companies. Two good questions to ask: who can change the rules, and who holds the keys?
3 questions. Tap an answer to see if you are right and why. Get 2 right to complete the module.
1. What does decentralised mean?
No single person, company or government is in charge. Many participants follow the same rules.
2. Which of these is a trade-off of a decentralised network?
There is no help desk to undo a mistake, and you are responsible for your own security.
3. Which two questions help you judge how decentralised something is?
Some projects are more decentralised than others. Who can change the rules and who holds the keys tell you a lot.
Learn / Lesson 3
Money is something everyone agrees has value, so we can swap it for goods and services. It makes life easier than barter, where you would need to find someone who wants exactly what you have.
People moved from barter to shells and metals, then coins, then paper notes issued by governments. Today most money is just numbers in a bank’s computer system. Our Trinidad and Tobago dollar is issued by the Central Bank of Trinidad and Tobago.
In 2008, after a major global financial crisis, a person or group using the name Satoshi Nakamoto published a paper describing a new digital money. The idea was money that moves between people directly, with no bank in the middle. Bitcoin launched in January 2009.
Crypto has not replaced the TT dollar. The Central Bank, the Securities and Exchange Commission and the Financial Intelligence Unit have warned that virtual currencies are not legal tender in Trinidad and Tobago. Bank money is also regulated and often protected in ways that crypto is not.

1. Which three jobs does money do?
Money lets us pay, keep value for later and compare what things are worth.
2. Who issues the Trinidad and Tobago dollar?
The TT dollar is issued by the Central Bank of Trinidad and Tobago.
3. When did Bitcoin launch?
A paper by Satoshi Nakamoto in 2008 described the idea, and Bitcoin launched in January 2009.
Learn / Lesson 4
Cryptocurrency is digital money that exists only on a blockchain. There are no physical coins or notes, and no bank issuing it.
The “crypto” part comes from cryptography, which is maths used to keep information secret and secure. It is what makes the records hard to fake and your ownership hard to steal.
The blockchain keeps the record of who owns what. Your wallet holds the secret keys that prove your coins are yours and let you send them. We cover wallets in a later lesson.
Some people hold it as an investment, some send money to friends or family abroad, and some use apps built on blockchains. Each network has its own rules for how new coins are created.
No government stands behind most cryptocurrencies. Their price depends on what people are willing to pay, so it can swing a lot, up or down.
Crypto is not guaranteed to hold its value, and rules about it differ from country to country. Scams are common, so go slowly and learn first.
3 questions. Tap an answer to see if you are right and why. Get 2 right to complete the module.
1. Where does the "crypto" in cryptocurrency come from?
Cryptography makes the records hard to fake and your ownership hard to steal.
2. What is the difference between a coin and a token?
Bitcoin, ether and SOL are coins with their own blockchains. Tokens are built on top of another blockchain.
3. Where does the value of most cryptocurrencies come from?
No government stands behind most cryptocurrencies, so the price depends on what people will pay.
Learn / Lesson 5
Bitcoin is the first cryptocurrency. It started in 2009 and runs on its own blockchain, with no bank or government in charge of it.
There will only ever be 21 million bitcoin. That fixed limit is one reason people compare it to something scarce, like gold.
Some people hold it as an investment, and some use it to send money across borders. Its price can rise and fall sharply, sometimes in a single day.
Only put in money you could afford to lose, and learn how to store it safely before you buy.

1. How many bitcoin will ever exist?
The fixed limit of 21 million is one reason people compare Bitcoin to something scarce, like gold.
2. When did Bitcoin start?
Bitcoin is the first cryptocurrency and started in 2009.
3. Which is the sensible way to approach Bitcoin?
The price can rise and fall sharply, so learn first and only use money you could afford to lose.
Learn / Lesson 6
Ethereum is a blockchain launched in 2015. Its coin is called ether (ETH). Unlike Bitcoin, it was designed so people can run small programs on it.
These programs are called smart contracts. They follow rules written in code, for example “if this payment arrives, then do that”. Many crypto apps are built on them.
Using Ethereum usually costs a small fee each time, and the fee changes with demand. Always check what you are connecting to before you approve anything.

Ethereum launched in 2015 and its coin is ether, written ETH.
3. What should you keep in mind when using Ethereum?
Using Ethereum usually costs a small fee that changes with demand. Check before you approve anything.
Learn / Lesson 7
Solana is a blockchain that launched in 2020. It is designed to handle many transactions quickly, with low fees. Its coin is called SOL.
Like Ethereum, it supports apps and smart contracts, so it competes in the same space.
Newer networks can be less proven, and Solana has had outages in the past. Faster and cheaper does not mean risk-free.

2. What is Solana designed to do?
Speed and low fees are what it is designed for. Like Ethereum, it supports apps and smart contracts.
3. Which statement is true?
Faster and cheaper does not mean risk-free.
Learn / Lesson 8
A crypto wallet is not like a purse that holds coins. Your coins live on the blockchain. The wallet holds the secret keys that prove they are yours and let you send them.
Your address (from your public key) is like an account number. You can share it so people can send you crypto.
Your private key is like a password that approves sending. Anyone who has it can take your coins, so never share it.
Most wallets give you a recovery phrase, usually 12 or 24 words. It can rebuild your wallet if you lose your phone. Write it on paper and keep it somewhere safe and offline. Never type it into a website, and never give it to anyone. Treat anyone who asks for it as a scammer, even if they say they are support.
Crypto transactions cannot be reversed. Check every address carefully, and consider sending a small test amount first. Be wary of anyone who contacts you offering help with your wallet.

Learn / Scam Watch
Crypto moves fast and transactions cannot be reversed, which is exactly why scammers like it. Most scams work the same way: they rush you, promise something too good to be true, or pretend to be someone you trust. Knowing the pattern is your best protection.
Three rules that cover most of it. Never share your recovery phrase or private key with anyone, ever. Nobody honest will ask for it. Never send crypto to “unlock”, “verify” or “release” something. And if something promises guaranteed profit, walk away.
Anyone promising fixed or risk-free profits, or offering to “double your crypto”, is not telling the truth. Real investments can lose money.
Posts or videos, often using a famous person’s name or face, say “send some crypto and get more back”. You never get it back.
A message or search ad sends you to a copy of a real exchange or wallet website. You type in your login or recovery phrase and they take everything. Check the web address carefully, and use bookmarks.
You post a problem and a “helper” messages you privately, or a stranger contacts you about your wallet. Real support will never ask for your recovery phrase or ask to see your screen.
Someone you met online builds trust over weeks and then “shares” an investment tip or platform. The platform is fake, and the money is gone once you send it.
A group hypes a little-known coin so you buy, then the organisers sell at the top. In a rug pull, the project’s creators simply take the money and vanish.
Copies of wallet or exchange apps that look real but steal your keys. Only install apps from the link on the official website, and check who published the app.
After you lose money, someone offers to get it back for a fee. They are often the same scammers, or their friends. Do not pay.

Learn / The Bitcoin Story · Module 1
The Bitcoin Story · Module 1 · 1990s to 2008 · 35 min
Bitcoin did not appear out of nowhere: it was the last piece of a search for digital cash that no bank or company controls, which had been going on for about twenty years.
Think about cash in your pocket. When you hand a $20 note to a vendor, you no longer have it. Nothing needs to check that, because the note is a physical thing that can only be in one place.
A digital file is different. When you send a photo, you keep your copy and your friend gets one too. That is useful for photos and a disaster for money: if digital coins could be copied, one person could spend the same coin again and again. This is called double spending.
For decades the usual answer was to put a trusted middleman in charge of the records. A bank keeps the list of who has what, and it says no if you try to spend money twice. That works, but it means you must trust the middleman to stay honest, stay open and stay in business.
Remember: Digital money needs a way to stop double spending. Until 2009 that always meant trusting a middleman.
In the late 1980s and 1990s a group of programmers and privacy campaigners, often called cypherpunks, wanted digital cash that protected privacy. They shared ideas by email and tried to build them.
DigiCash was one of the best known. A single company ran it, and when the company went bankrupt in 1998 the money went with it. In 1997 Adam Back proposed Hashcash, which asked a computer to do a small amount of work to prove effort. That proof-of-work idea was later reused in Bitcoin. In 1998 Wei Dai described b-money, and around the same time Nick Szabo designed Bit Gold, which he wrote about publicly in 2005. Both were designs on paper that were never launched as working networks.
Each attempt solved part of the puzzle. None solved all of it: money that no one company runs, that stops double spending, and that people actually use.
Remember: Bitcoin joined together ideas that already existed. Its new step was making them work without a company in charge.
In September 2008 the US investment bank Lehman Brothers filed for bankruptcy, on 15 September. Banks around the world were rescued by governments or failed. Many people lost savings, jobs or homes, and many began asking how much they should trust the institutions that kept their money.
Bitcoin’s first block, created in January 2009, carries a message that refers to a newspaper headline about bank bailouts. The headline is a timestamp, and many read it as a comment on why the project began.
It is fair to say the crisis shaped the mood in which Bitcoin was born. It is not fair to claim Bitcoin would have prevented it, or that it is a cure for every banking problem.
Remember: Bitcoin arrived at a moment when trust in banks was low. That is its backdrop, not a promise.

The Bitcoin Story · Module 2 · 2008 to 2010 · 35 min
On 31 October 2008 someone using the name Satoshi Nakamoto published a nine-page paper describing digital cash with no bank in the middle, and the network started a little over two months later.
On 31 October 2008 someone using the name Satoshi Nakamoto sent a nine-page paper to a cryptography mailing list. Its title was Bitcoin: A Peer-to-Peer Electronic Cash System.
Peer-to-peer means directly between people. The paper proposed that instead of a bank keeping the record of who owns what, many ordinary computers would each keep a copy of the same shared record. New entries are bundled into blocks, and the blocks are linked in order into a chain. That is the blockchain.
To keep everyone honest, the computers that add blocks, called miners, must spend real computing effort, which is the proof of work. Changing the past would mean redoing all that work, which quickly becomes impractical.
Remember: The white paper’s idea: a shared record kept by many computers, protected by proof of work, with no bank in the middle.
The first block, the genesis block, was created on 3 January 2009. A few days later, on 9 January, the first version of the software was released so anyone could run it.
Within the month, in mid-January 2009, the first transfer between two people took place, from Satoshi to the programmer Hal Finney. That mattered because it showed coins could move from one person to another.
In October 2009 the first published exchange rate put one bitcoin at less than one US cent. On 22 May 2010 a programmer paid 10,000 bitcoin for two pizzas, worth about $40 at the time. The date is now celebrated as Bitcoin Pizza Day.
Remember: By 2010 Bitcoin worked, had a price, and had a first real purchase. It was still tiny.
Nobody has proven who Satoshi Nakamoto is. The name is a pseudonym, and it may be one person or a group. Satoshi wrote on forums and by email, worked on the software, and then faded out, with the last messages dating from 2010 and 2011.
Many people have been named over the years and none has been proven. Be careful with any headline that claims to have solved it.
The mystery has a useful side: nobody can be said to run Bitcoin. It is maintained by volunteers and companies who can propose changes, but changes only matter if the people running the network choose to adopt them.
Remember: We do not know who Satoshi is, and Bitcoin has carried on without them.

The Bitcoin Story · Module 3 · 2010 to 2012 · 35 min
In its first three years Bitcoin went from a hobby for programmers to something with a price, exchanges, a first big crash and its first halving.
For its first year Bitcoin had no market price at all. Early users mined coins on home computers and traded them mostly with each other.
Once exchanges opened, prices appeared. In February 2011 one bitcoin first reached one US dollar. The pizza purchase of May 2010 is told so often because it is one of the earliest clear examples of someone spending bitcoin on a real thing, and because of how large those 10,000 coins would be worth later.
Be careful with that second part. Looking back and counting what an early coin would be worth now is easy, but it says nothing about what any coin will be worth next.
Remember: A price is just what people are willing to pay at a moment. In 2010 almost no one was paying.
An exchange is a website where people swap bitcoin for regular money. Mt. Gox began trading bitcoin in July 2010 and became one of the largest of its time.
Interest built through early 2011 and the price peaked near $32 on Mt. Gox in June 2011. Then it fell, and by November 2011 it was about $2, a fall of around 90 percent.
That cycle of excitement, a sharp rise, then a sharp fall would repeat many times. It is why people describe Bitcoin as volatile: its price can move very far in a short time in either direction. Exchanges also carry their own risk, because coins held there depend on the exchange staying safe and honest.
Remember: Volatility has been part of Bitcoin from the start. Nobody can promise which way it will move.
Bitcoin’s software creates new coins as a reward to the miners who add blocks. Satoshi built in a rule that the reward would be cut in half at fixed points, about every four years, or every 210,000 blocks. This is the halving.
Because of the halvings the total number of bitcoin is capped at 21 million. The first halving came on 28 November 2012, when the reward fell from 50 to 25 bitcoin per block.
A new block arrives about every ten minutes, so about 144 a day. That means new coin creation fell from 7,200 a day to 3,600 a day overnight. The table under Do it yourself, at the end of this module, shows every era.
Remember: The halving is a fixed rule written in the software. It makes new coins arrive more slowly over time.
| When | What happened | Why it matters |
|---|---|---|
| July 2010 | Mt. Gox begins trading bitcoin | One of the first big exchanges, and later a warning story |
| February 2011 | One bitcoin first reaches one US dollar | A first sign of wider interest |
| February 2011 | The Silk Road marketplace launches | Bitcoin gets an early link to illegal trade that it still has to answer for |
| June 2011 | The price peaks near $32 on Mt. Gox | A first speculative rush |
| November 2011 | The price falls to about $2 | Shows how fast prices can fall |
| 28 November 2012 | The first halving: the reward per block falls from 50 to 25 bitcoin | New coins now arrive at half the pace |

From near $32 to about $2, a fall of around 90 percent.
4. How many new bitcoin per day after the first halving (November 2012)?
The reward fell from 50 to 25, so about 144 blocks × 25 = 3,600 a day.
Work out how many new bitcoin were created each day in each era. A new block arrives about every 10 minutes, so about 144 blocks a day. Multiply 144 by the reward.
| Era | Reward per block | New bitcoin per day |
|---|---|---|
| 2009 to 2012 | 50 | 7,200 |
| 2012 to 2016 | 25 | 3,600 |
| 2016 to 2020 | 12.5 | 1,800 |
| 2020 to 2024 | 6.25 | 900 |
| From April 2024 | 3.125 | 450 |

Bitcoin survived the collapse of its biggest exchange and a long argument about its own rules, and came out with more users, new upgrades and a split into two coins.
By 2013 Mt. Gox handled a very large share of all bitcoin trading. In February 2014 it stopped withdrawals and then filed for bankruptcy. A very large number of customers’ coins were reported missing, and many people lost money.
The lesson people took is a saying you will hear often: not your keys, not your coins. If you leave coins on an exchange, you are trusting the exchange to keep them safe and give them back.
Holding your own keys, for example in a wallet you control, removes that trust but adds a different responsibility. If you lose your keys, nobody can restore them. Cold storage, which keeps keys offline, is one way people reduce the risk of being hacked.
Remember: Every way of holding crypto has a trade-off. The trade-off is between trusting someone else and being responsible yourself.
Each block can only hold a limited amount of data, so only a limited number of transactions fit into each one. As more people used Bitcoin, fees rose and payments slowed, and the community argued about what to do.
One side wanted bigger blocks, so more transactions fit. The other worried that bigger blocks would make it too costly for ordinary computers to run the network, which could make Bitcoin less open.
SegWit, an upgrade that uses block space more efficiently, was activated in August 2017. On 1 August 2017 a group that wanted bigger blocks split away to create Bitcoin Cash, a fork, so there were then two chains with a shared history. A fork like this is permanent. Anyone who held their own bitcoin keys before the split also ended up with the same amount of Bitcoin Cash.
Remember: A fork happens when a community cannot agree. Both sides had real arguments.
The 2016 halving took place on 9 July 2016, cutting the reward to 12.5 bitcoin. Through 2017 the price climbed steeply, passing $1,000 again and then reaching a peak near $19,800 on 17 December 2017.
Newspapers and television covered it every day. New buyers arrived, many hoping to catch the rise, and the first wave of ICOs (token sales by new projects) appeared, mostly on Ethereum. Early 2018 brought the fall. By the end of 2018 the price was down about 80 percent from the top.
A sharp rise in attention followed by a sharp fall is a pattern, not a rule. The best protection is to be wary when everybody around you suddenly seems certain.
Remember: The loudest moment of excitement was also the peak. That does not always happen, but it has happened before.

From a long slump in 2018 to companies, a whole country and some very big failures, Bitcoin became part of the wider money conversation, and so did its risks.
After the 2017 peak came a long slump nicknamed the crypto winter. The price bottomed near $3,200 in December 2018 while many projects shut down.
While prices were low, developers kept building. The Lightning Network, which went live on Bitcoin’s main network in 2018, is a second layer on top of Bitcoin. Two people open a channel, make many quick payments between them, and only the final result is written to the main chain. This aims to make small payments faster and cheaper.
Lightning is still a work in progress, with trade-offs of its own, so treat its claims with the same care as any other.
Remember: Quiet years can be when the foundations are built.
The third halving took place on 11 May 2020, cutting the reward to 6.25 bitcoin. A few months later, in August 2020, the software company MicroStrategy began holding bitcoin as a company asset, and other public companies followed.
On 7 September 2021 El Salvador became the first country to make Bitcoin legal tender, and at first its law required businesses to accept it. The decision was debated heavily, both inside the country and abroad. In early 2025, under a loan agreement with the International Monetary Fund, El Salvador changed the law so that private businesses can choose whether to accept bitcoin, and taxes can no longer be paid with it.
These steps show that Bitcoin moved from a hobby into the wider money conversation. They do not show that any of these choices was right for everyone.
Remember: Bitcoin became part of the wider money conversation, and not everyone agreed it should be.
In November 2021 the Taproot upgrade activated, improving privacy and flexibility, and the price reached a record near $69,000.
Then 2022 brought a string of failures. In May the Terra and Luna coins collapsed, wiping out huge sums. Lending firms such as Celsius failed. In November the exchange FTX failed, and the price fell to about $15,500.
These were failures of companies and of risky promises, not of the Bitcoin software, which kept running without a break. The lesson matches Mt. Gox: be careful who you trust with your coins, and be wary of any promise of steady high returns.
Remember: In 2022 the software worked as designed. What failed was trust in companies.

Since 2024 Bitcoin can be bought through regulated funds, passed $100,000 and set a record near $126,000 in October 2025, then fell well back, which shows again that past prices do not tell you what comes next.
An ETF is a fund you can buy and sell through an ordinary investment account. A spot Bitcoin ETF holds real bitcoin and its price follows Bitcoin’s price.
In January 2024 US regulators allowed the first spot Bitcoin ETFs to start trading. This was a big step because it let investors, including large firms and pension managers, get exposure without learning how to hold coins.
An ETF is still an investment that can lose value, and it comes with fees. Buying one does not give you the coins themselves or the ability to send them yourself.
Remember: ETFs made Bitcoin easier to buy for many people. They did not make it safer.
The fourth halving was on 20 April 2024, cutting the reward from 6.25 to 3.125 bitcoin per block. That means about 450 new coins a day instead of about 900.
In December 2024 the price passed $100,000 for the first time, a level that few people expected a decade earlier.
Some people point to the halving as a reason the price rises afterwards. Others note that only a handful of halvings have happened, too few to prove a rule. Treat any confident forecast with caution.
Remember: A few repeats do not make a law.
In October 2025 Bitcoin reached a record near $126,000, with small differences between sources. In 2026 the price then fell well back from that level.
Together, the record and the fall repeat what earlier chapters showed: Bitcoin’s price can move far and fast in both directions, and a record high tells you what has happened, not what will happen.
The next halving is expected around 2028, when the reward would fall to 1.5625 bitcoin if the schedule holds. Check current prices on our Markets page, and read the other chapters again before making any decision. This is education, not financial advice.

Ethereum started from one question: what if a blockchain could run small programs, not only keep track of coins?
Bitcoin is built to do one job very well: move and record money. Its programming language is deliberately simple, because every extra feature is another place for something to go wrong.
That left a gap. People who wanted to build other things, such as a shared record of who owns a domain name, or a contract that pays out automatically when a condition is met, found Bitcoin hard to use for it. Some tried to build on top of Bitcoin, and some built entirely separate chains.
A young programmer named Vitalik Buterin followed these experiments closely and came to believe that a different approach would work better: a blockchain with a general-purpose programming language built in.
Remember: Bitcoin is simple on purpose. Ethereum asked what happens if a blockchain is flexible on purpose instead.
In late 2013 Vitalik Buterin shared the Ethereum white paper. It described a blockchain with its own programming language, so that anyone could write programs that run on the network and keep their results on the shared record.
In January 2014 the project was announced at a Bitcoin conference, and a group of co-founders joined to help build it. In April 2014 Gavin Wood published the Yellow Paper, a precise technical description that other programmers could build from.
In the summer of 2014 a public presale of ether, the network’s coin, raised money to pay for the early work. Selling coins before a network exists is a way of funding that later became very common, and, as Ethereum module 4 explains, also very risky.
Remember: The idea came from one person’s white paper, and a team turned it into something real.
A smart contract is a program stored on a blockchain. When its conditions are met, it runs exactly as written, and everyone can see that it did.
The classic picture is a vending machine. You put in the right amount, press a button, and the machine hands over the snack. No shop assistant has to agree and nobody can change their mind halfway. A smart contract works the same way, but with digital items and money.
The idea is older than Ethereum. The computer scientist Nick Szabo wrote about smart contracts in the 1990s. What changed is that a blockchain gave them somewhere to run that no single company controls. The name is a little misleading, though: a smart contract is not smart, it only follows its code, and it is not necessarily a legal contract.
Remember: A smart contract does exactly what its code says, every time. That is its strength and its risk.
| When | What happened | Why it matters |

Ethereum went live on 30 July 2015 as an early, experimental release, then grew up through planned upgrades over the following year.
Building a network takes money, so in the summer of 2014 the team ran a public presale of ether. People could pay in bitcoin and receive ether when the network started.
A non-profit organisation, the Ethereum Foundation, was set up to support the work. Its job is to fund research and development and help the community, but it does not own or control Ethereum.
Nobody owns Ethereum. Like Bitcoin, it is run by many computers around the world, and changes need wide agreement among the people who run them.
Remember: A foundation can support a network without owning it.
Ethereum went live on 30 July 2015 with a release called Frontier. It was an early version, aimed at developers who were comfortable with rough edges, not at ordinary users.
The network has its own coin, ether, often written as ETH. Ether is used to pay for running programs on the network. The fee is measured in a unit called gas, much like fuel for a car: the more work a program does, the more gas it burns.
Gas matters because it stops anyone from filling the network with endless work for free. It also means that when the network is busy, everyone competes for limited space, which pushes fees up.
Remember: Ether is the coin and gas is the fee for doing work on the network.
The developers planned Ethereum as a series of stages, each with a name. The second, called Homestead, activated in March 2016 and was the first major step towards a stable network.
A change like this is an upgrade. Everyone who runs the network has to install new software before a set point, and from then on the new rules apply. When it goes smoothly, almost nobody outside the community notices.
Developers began to build the first experiments on Ethereum: tokens, voting tools and games. Some were clever and some were rough. One of them, The DAO, became the subject of the biggest crisis in Ethereum’s early history, covered in the next module.
Remember: Upgrades are how a live network changes without starting again.

In June 2016 an attacker drained about 3.6 million ether from a large crowd-funded project called The DAO, and the community’s answer split Ethereum into two chains.
DAO stands for decentralised autonomous organisation. The DAO was the best-known example: a fund run by smart contract code, where people put in ether and then voted on which projects it should back.
It launched in the spring of 2016 and collected a very large amount of ether, making it the biggest crowd-funded project of its time. Many people saw it as a glimpse of how organisations could work without bosses or banks.
But the code had been written quickly and not everyone had been given time to check it carefully. Some developers had warned about problems before the attack.
Remember: The DAO showed the promise of smart contracts and, soon after, their danger.
In June 2016 someone found a flaw in The DAO’s code. By exploiting it, they began draining ether out of the fund, about 3.6 million ether in total.
Importantly, the attacker did not break Ethereum itself. They used the contract in a way the builders never intended, but that the code technically allowed. Many people said the code had done exactly what it was written to do.
That is the core risk of smart contracts. A program does what it says, not what its authors meant, and once money is inside there may be no way to take it back.
Remember: Ethereum worked as designed. The mistake was in one program built on top of it.
The community had to decide what to do. One side argued that the theft was a clear case of something going badly wrong and that the chain should be changed to return the money. The other side argued that a blockchain is only trustworthy if its history is never rewritten, even when the result is unfair.
In July 2016 most of the community supported a hard fork, a change to the rules that is not compatible with the old ones, which moved the stolen funds to a recovery contract. Some people refused to move, and kept running the original chain. It continues as Ethereum Classic, with its own coin, ETC.
Both sides had a real argument. The episode is still discussed as a lesson in how far a community should go to fix a mistake, and in the cost of being wrong.
Remember: There are now two coins, ETH and ETC, because a community could not agree. Neither side was foolish.

Ethereum made it easy for anyone to create a token, which fuelled a boom in 2017, many failed or fraudulent projects, and a network that sometimes struggled with its own popularity.
Ethereum’s coin is ether, but the network can also hold tokens. A token is a digital item created by a smart contract, such as points in a game, a share in a project or a stablecoin that tries to stay at one US dollar.
In late 2015 a shared standard called ERC-20 was proposed, setting out the common rules a token should follow, so wallets and exchanges could support any token that followed them. That made creating a token quick and easy.
The difference is easy to remember. A coin, like ether, runs on its own blockchain. A token is built on top of someone else’s blockchain.
Remember: A coin has its own chain. A token lives on someone else’s.
An ICO, or initial coin offering, is when a new project sells its own tokens to raise money. In 2017 hundreds of projects did this, often raising millions of dollars in a few hours.
Some were serious attempts to build something useful. Many had a polished website, big promises and no working product, and some were outright scams. Because anyone could create a token in minutes, there was no gatekeeper checking the claims.
Through 2018 many ICO tokens lost most of their value, and regulators in several countries began to pay close attention. The lesson is simple and still useful: promises are not products.
Remember: If a project promises guaranteed returns or pressures you to hurry, treat that as a warning, not an opportunity.
In December 2017 a game called CryptoKitties let people collect and breed digital cats. It became so popular that it clogged the network, and fees and waiting times rose for everyone, not just the game’s players.
The cause is built into how Ethereum works. Only so much fits into each block, so when more people want space than there is room, they offer higher fees to be first in the queue.
Developers answered with a series of planned upgrades, including Byzantium in October 2017 and Constantinople in February 2019, but the real fix would take years. Congestion became one of the main problems the next chapters deal with.
Remember: When a network is popular, its fees go up. Making it faster and cheaper is called scaling.

In 2020 and 2021 Ethereum became the home of apps that lend, swap and collect without a bank, which also pushed fees to levels that priced many ordinary people out.
DeFi means financial services such as lending, borrowing and swapping one asset for another, run by smart contracts instead of a bank or broker. Anyone with a wallet could use them, at any hour, from any country.
In the summer of 2020 DeFi grew very fast, a period often called DeFi summer. Large amounts of money moved into these apps, drawn by the chance to earn interest or fees.
The same features carried risks. Code can have bugs, hackers target large pools of money, prices can swing sharply, and there is no customer service desk that can reverse a mistake.
Remember: DeFi removes the middleman and also removes the safety net.
On 1 December 2020 a separate chain called the Beacon Chain launched alongside the main one. It introduced staking, in which people lock up ether to help run the network and earn rewards for doing it honestly.
This was preparation. The Ethereum developers planned to switch the main network from proof of work, in which miners compete using electricity, to proof of stake, in which participants who have locked up ether take turns validating blocks.
The Beacon Chain ran quietly for almost two years, collecting stakers and testing the system, before the two chains were joined in 2022.
Remember: The Beacon Chain was the groundwork for the biggest change in Ethereum’s history.
In 2021 NFTs, or non-fungible tokens, went mainstream. An NFT is a token that is one of a kind, and it was used for digital art, collectables and game items. Some sold for very large sums, and many later lost most of their value.
All this activity pushed fees very high. At busy times a simple transaction could cost far more than the value being moved, which priced out many ordinary people.
In August 2021 the London upgrade changed how fees work. Part of each fee is now burned, meaning permanently removed from the supply of ether. It did not make fees cheaper by itself, but it made them more predictable. Cheaper fees came later, from a different approach covered in the next module.
Remember: High fees were not a glitch. They were what happens when many people want the same limited space.

On 15 September 2022 Ethereum changed how it agrees on blocks, from proof of work to proof of stake, and a series of upgrades since then has made everyday use much cheaper.
On 15 September 2022 Ethereum switched from proof of work to proof of stake in an upgrade known as the Merge. The old chain and the Beacon Chain were joined, and from then on blocks were agreed by stakers, not miners.
The main effect was on energy use. Proof of stake needs far less electricity because it does not rely on competing computers, and the drop was very large.
It did not make fees cheaper or the network faster on its own, a common misunderstanding. Those improvements needed other changes, which came in the following years.
Remember: The Merge changed how Ethereum is secured. It did not change what it costs to use.
In April 2023 the Shapella upgrade let stakers withdraw their ether for the first time. Until then, ether that had been staked was locked in.
The big step for fees was a different idea: layer 2 networks. A layer 2 is a separate network built on top of Ethereum that handles many transactions quickly and cheaply, then posts a summary back to Ethereum for safety.
In March 2024 the Dencun upgrade added blobs, a cheaper way for layer 2 networks to post their data. As a result, using a layer 2 became far cheaper. In mid-2024 US spot ether ETFs also began trading, giving investors a new way to get exposure without holding ether themselves.
Remember: Ethereum scaled by letting other networks do the busy work on top of it.
The Pectra upgrade activated on 7 May 2025. It increased blob capacity and added features that let ordinary accounts behave more like smart wallets.
The Fusaka upgrade followed on 3 December 2025. It introduced a new way of checking data so the network can handle more of it without every computer storing everything.
The next planned upgrade is called Glamsterdam. In October 2026 it began running on a public test network, but no date for the main network had been set when this lesson was checked. Upgrade dates often move, so check an up-to-date source. As always, this is history and education, not financial advice.
Remember: Upgrades keep coming, and their dates can slip.

The Solana Story · Module 1 · 2017 to 2019 · 35 min
Solana began in 2017 with one engineer’s question: could a blockchain be much faster if its computers could agree on the order of events without constant chatter?
Bitcoin and Ethereum both pay for their safety with speed. Every computer on the network has to agree on which transactions came first, and that takes messages going back and forth, so only so many transactions fit into each block.
As you saw in the Ethereum story, when many people want space on a busy network, fees go up and waits get longer. Developers were already working on fixes for this, such as layer 2 networks.
Solana took a different approach. Instead of building on top of an existing chain, it set out to make one chain fast from the start, even if that meant harder demands on the computers that run it.
Remember: Solana’s big bet is speed on the main chain itself.
Anatoly Yakovenko was an engineer who had worked on telecom software at Qualcomm, a company that makes chips for phones. In November 2017 he published a white paper describing an idea he called Proof of History.
Think of a clock that everyone can check. If each event carries a trusted timestamp, the computers no longer need to keep asking each other what happened first, because the order is already there. Proof of History is a way of building that shared clock into the record itself.
It is not a replacement for proof of stake or proof of work. Solana uses Proof of History together with proof of stake, which is how the network agrees on which blocks to accept.
Remember: Proof of History is a shared clock built into the chain, so computers waste less time agreeing on order.
In 2018 Yakovenko and a small team, including the engineer Greg Fitzgerald, founded the company that became Solana Labs. The name is a nod to Solana Beach, a surf town in California where some of the founders lived.
In 2019 the team ran public test networks, including one called Tour de SOL, where volunteers ran the software and tried to break it. A test network uses coins with no real value, so mistakes are cheap.
Early backers put money into the company and the project, and a private sale of tokens helped fund the work. As with any early project, those first investors held a lot of the supply, which is something to keep in mind when you read about price swings.
Remember: Test networks let a project learn from mistakes before real money is involved.

Solana’s main network opened in March 2020 as a beta. Its low fees and quick confirmations attracted developers in a year when the whole market was changing.
On 16 March 2020 Solana’s main network went live as a beta release. A mainnet is the real network, where coins have real value. Beta means the team told people openly that it was still being tested and could change.
A non-profit, the Solana Foundation, was set up in Switzerland to support the ecosystem. Like the Ethereum Foundation, it supports the community without owning the network.
Calling a network a beta is honest and common, but it also means early users take on more risk. In its first years Solana was still working out problems that older chains had already faced.
Remember: Beta means unfinished. Early users carry extra risk.
The network’s coin is SOL. It pays the fees for using the network, and people who hold SOL can stake it, which means lending its weight to validators, the computers that confirm transactions, and earning a reward.
Solana’s fees are very small, usually a fraction of a US cent per transaction at normal times. That matters if you want to do many small things, like trading or playing a game, where a fee of a few dollars would make it pointless.
Low fees come with a trade-off. If a transaction costs almost nothing, there is less to stop someone from flooding the network with junk, which becomes important in the next module.
Remember: Cheap fees open the door to lots of small actions, and to lots of spam.
Developers began to build on Solana in 2020. The best known early project was Serum, a trading exchange that ran on the blockchain itself and was backed by people connected to the company FTX, a link that would matter later.
Because trades were fast and cheap, Solana began to look like a place for decentralised finance, or DeFi, a theme you met in the Ethereum story. Wallets, token swaps and games followed.
It was still a small ecosystem by the end of 2020, and the price of SOL was far below where it would reach a year later.
Remember: Early growth was about developers and traders. The mass audience came later.

In 2021 Solana’s price rose enormously and NFTs and DeFi apps poured in, but the network also went down several times under the load, which became its main criticism.
From a very low starting point at the start of 2021, SOL’s price rose many times over during the year, reaching a peak near $260 in November 2021. It was one of the best-performing large coins of that year.
Several things came together. NFTs went mainstream and Solana’s low fees suited them. DeFi apps grew. Big investors and well-known funds backed the ecosystem. And the whole crypto market was rising.
A rising price is not proof of a better network. Everything in crypto was climbing that year, and when the mood changed the fall was equally dramatic.
Remember: In a boom almost everything goes up. That says little about which projects are strong.
A network outage means the blockchain stops producing blocks, and nobody can send transactions until the validators restart it. On 14 September 2021 Solana stopped for about 17 hours after a flood of bot transactions, aimed at grabbing spots in a popular token sale, overwhelmed it.
Further stalls followed in 2022, each lasting several hours, caused by things like bot-driven NFT minting or software bugs. In each case the validators had to coordinate and restart the chain.
Critics argued that a network with that many outages could not be called decentralised or reliable. Supporters argued that these were growing pains that the developers were fixing, and that no funds were lost.
Remember: Speed was only valuable if the network stayed up.
If you use a bank app and it goes down, you are annoyed. If you use a financial app on a blockchain and it goes down, you may be unable to move your money at a moment when prices are moving fast.
Bitcoin has kept producing blocks since 2009, and Ethereum since 2015, with no network-wide halt of the kind Solana had. That track record is a big part of why people trust them. A newer network has to build the same record, one year without incident at a time.
When you read about any network, check not only how fast it is but also how long it has run without a stop, and how it dealt with the last problem.
Remember: Reliability is earned over years, not claimed in a launch post.
| When | What happened | Why it matters |

| 2021 | SOL rises many times over during the year | A year of fast growth in NFTs and DeFi |
| 14 September 2021 | A network stall of about 17 hours | The first big outage, caused by a flood of bot traffic |

In 2022 a major bridge hack and the failure of FTX, one of Solana’s biggest backers, sent SOL’s price down by around 95 percent from its peak. Many assumed the network was finished.
A bridge is a service that lets you move tokens from one blockchain to another. Wormhole connected Solana to Ethereum and other chains. In February 2022 an attacker exploited a flaw in its code and took about $320 million worth of tokens.
The company Jump Crypto, which backed the bridge, put in the missing funds to cover the loss, so users were made whole. That is not guaranteed in a hack, and it is one of the reasons people call bridges one of the riskiest parts of crypto.
The episode also hurt the reputation of Solana’s ecosystem, even though the flaw was in the bridge’s code and not in Solana itself.
Remember: Bridges concentrate a lot of money in one place, which makes them a favourite target.
The exchange FTX and its sister trading firm Alameda Research had been among the biggest supporters of Solana. They held a large amount of SOL and invested in many Solana projects.
In November 2022 FTX collapsed, as you read in the Bitcoin story. Because so much of its holdings were tied to Solana, the price of SOL dropped sharply, from around $36 in early November to below $10 by the end of the year, and many projects that relied on FTX money shut down.
The lesson is concentration. When a lot of a network’s money, attention or credibility comes from a single backer, its fortunes depend on that backer.
Remember: A project that depends on one big supporter is only as strong as that supporter.
In the bear market that followed, many people wrote Solana off. But the developers and community kept building. Validators kept running, and projects that survived the FTX collapse had less hype and more substance.
In June 2022 the company behind Solana announced a Solana-focused phone called Saga, which began shipping in spring 2023. It was an attempt to bring Solana to ordinary users through a phone with a built-in crypto wallet.
The network suffered another outage in February 2023, lasting many hours after a software upgrade problem, which was a reminder that the reliability problem had not gone away. It was also, as it turned out, close to the last of the big ones.
Remember: The bear market is where you find out which projects have real builders behind them.

From late 2023 Solana made a surprising comeback, helped by airdrops, cheap NFTs, a boom in memecoins and a network that finally stayed up.
An airdrop is when a project gives free tokens to people who used its app or network. They were designed to reward early users, but they also draw crowds who hope to receive them.
Through late 2023 the price of SOL climbed back, passing $100 in December. In January 2024 a popular Solana trading app, Jupiter, announced a large airdrop, which brought a surge of new users and activity.
Compressed NFTs, introduced in 2023, let developers create digital items for a tiny fraction of the previous cost. That made it practical to give out millions of them, for example as tickets or rewards.
Remember: Free tokens attract users. They do not guarantee that users stay.
A memecoin is a token created around a joke or a trend, such as a dog picture, with no real product behind it. Bonk, launched in December 2022, and dogwifhat, in late 2023, were early Solana examples.
In January 2024 the app Pump.fun made it possible to launch a new memecoin in a few clicks. Thousands appeared every day. A few made some people a lot of money, and the great majority went to nearly nothing, and many were outright scams.
Memecoins show both sides of Solana’s low fees. They made trading easy and cheap, and they also made it easy to lose money quickly. If you take one thing from this lesson, let it be that a cheap, fast network does not make a coin worth owning.
Remember: Easy to buy does not mean worth buying. Most memecoins fall to almost nothing.
On 6 February 2024 the network stopped again, this time for about five hours, after a bug in the software. It turned out to be the last major outage for a long time, as developers hardened the software and added improvements.
In March 2024 the price of SOL climbed to roughly $200, its highest level since the 2021 peak. By then the network had gone through more than a year of high traffic.
A second team, led by the firm Jump Crypto, was building a separate piece of validator software called Firedancer. Having two independent programs run the network makes it less likely that a single bug stops everything.
Remember: Stability returned slowly. Having more than one version of the software helps.

In 2025 Solana set a new record, gained a regulated fund in the United States and worked on big upgrades, in a market that kept rising and falling sharply. Recent dates are the most likely to need checking.
In January 2025 a memecoin linked to the US president was launched on Solana, bringing a burst of trading to the network. SOL reached a record of close to $295 that month.
The record did not last. SOL fell back through 2025, as the wider market went through sharp swings. Higher traffic also showed the network could handle large volumes, which earlier versions would have struggled with.
As with Bitcoin, a record high only shows where the price has been. It says nothing about where it goes next.
Remember: Every record is eventually followed by something. Nobody can say in advance what.
In late October 2025 the first US exchange-traded funds that hold Solana, or ETFs, began trading. As with the Bitcoin and Ether funds you met earlier, they let people get exposure through an ordinary investment account without holding coins themselves.
In September 2025 Solana’s validators voted to approve a major change to how they agree on blocks, known as Alpenglow. It went live on the main network on 21 October 2026. Anza, the team that built it, says it cuts the time for a transaction to become final from about 13 seconds to roughly 150 milliseconds. That is the stated target: independent measurements had not yet been published when this lesson was updated, and some analysts put the old time nearer 6 seconds.
Firedancer, the second independent validator program, began running on the main network. It is a sign of the network maturing, because it makes it less dependent on any single piece of software.
Remember: Funds make Solana easier to buy. Upgrades aim to make it faster and sturdier.
For any network, three questions are worth asking. Does it stay up? Is the activity real, or just speculation? And is control spread across many validators and developers, or held by a few?
Solana’s record on staying up has been much better since early 2024. Its activity includes real payments, trading and apps, alongside a large amount of speculation. And, like all of these networks, it is still debated how decentralised it really is.
Dates for 2025 and 2026 events are recent and can be revised, so check an up-to-date source before relying on them, and look at our Markets page for current prices. This is education, not financial advice.

Mining is how some blockchains, including Bitcoin, check new transactions and add them to the chain. People called miners use powerful computers to do it, and they are paid for the work.
Miners collect waiting transactions into a block. Then their computers race to solve a hard puzzle by making an enormous number of guesses. The first one to find a valid answer adds the block to the chain and is rewarded with newly created coins plus the fees from the transactions in it.
This method is called proof of work. The puzzle cannot be shortcut, so the only way to win is to do real work.
Mining does two jobs. It keeps the network honest, because changing an old block would mean redoing all the work after it, which costs a huge amount of electricity and equipment. It is also how new coins enter circulation. On Bitcoin, the reward per block is cut in half roughly every four years, an event called the halving.

DeFi is short for decentralised finance. It means financial services such as trading, lending and borrowing that run on a blockchain through smart contracts, with no bank or broker in the middle.
A smart contract is a program on a blockchain that follows rules written in code. In DeFi, those programs hold the money and carry out the deal. To use one, you connect your own wallet to an app. There is usually no sign-up form, and most of these apps are open at any hour.
Two common examples are decentralised exchanges, where people swap one token for another directly from their wallets, and lending apps, where people lend tokens to earn interest or borrow against tokens they put up as security.
DeFi shows what blockchains can do beyond sending money. Anyone with a wallet and an internet connection can use the same tools, and the rules of many apps are written in open code that anyone can read.

Beginner · Tokens and Stablecoins · about 3 min read
A coin is the main digital money of its own blockchain. A token is a digital asset created on top of someone else’s blockchain. People often say “coins” for both, but the difference matters.
Bitcoin runs on the Bitcoin blockchain, ether on Ethereum and SOL on Solana. Each one is the native coin of its chain. It pays the fees on that network and rewards the people who keep it running.
Tokens are created using the token tools of a chain that supports them, such as Ethereum or Solana, often through smart contracts. They do not need a blockchain of their own. A token can stand for many things: a dollar-linked currency, a vote in a project, a point in a game, or a share of something.
When you send a token, you usually pay the network fee in that chain’s own coin. To send a token on Ethereum you need some ether, and on Solana you need some SOL. The same token can also exist on more than one network, so always check that you are sending to an address on the same network.

1. What is a coin?
Bitcoin, ether and SOL are native coins. Each runs on its own blockchain.
2. Where are tokens built?
Tokens use the blockchain of another network, such as Ethereum or Solana.
3. You want to send a token on Ethereum. What do you usually need as well?
Fees are paid in the chain’s own coin, so Ethereum fees are paid in ether.

A stablecoin is a crypto token designed to hold a steady price, most often one US dollar. It tries to give you the speed of crypto without the big price swings.
People use stablecoins to move money between exchanges and wallets, to send money abroad, and to park value in dollars while they decide what to do next. Most people get them through an exchange.
Stablecoin, peg, reserves, issuer, algorithmic stablecoin.
3 questions. Tap an answer to see if you are right and why. Get 2 right to complete the module.
1. What is a stablecoin designed to do?
Stablecoins aim to keep a steady value, most often matching the US dollar.
2. Which kind of stablecoin relies mainly on code, not dollars in reserve, to hold its price?
Algorithmic stablecoins depend on code to keep the peg, and TerraUSD showed it can fail.
3. What does it mean if a stablecoin loses its peg?
A peg is the target price. Losing it means the coin is no longer worth what it promised.

Crypto prices move because of supply and demand: how many people want to buy compared with how many want to sell. When more people want to buy than sell, the price tends to rise. When more want to sell, it tends to fall.
Crypto trades every hour of every day, but the buyers and sellers who steady prices are fewer at quiet times such as weekends. Some traders also borrow money to trade. When prices fall, their positions can be closed automatically, which forces more selling and can make a drop steeper.
Supply and demand, volatility, market mood, liquidation.
3 questions. Tap an answer to see if you are right and why. Get 2 right to complete the module.
1. What mainly sets a crypto price?
If more people want to buy than sell, the price tends to rise, and the reverse.
2. Why can crypto prices swing more than many other markets?
Round-the-clock trading, quiet periods with fewer traders, and borrowed money can all make moves bigger.
3. Which is the safest approach?
Nobody can reliably predict prices, so protect yourself first.

In Trinidad and Tobago, crypto is not legal tender, and since December 2025 a new law controls the businesses that deal in it. Officials say the law is not aimed at individuals using crypto for personal transactions.
Before you use a crypto business based in Trinidad and Tobago, check whether the TTSEC lists it as approved. The TTSEC publishes a list of approved providers on its website and has issued public warnings about companies that are not registered with it. That March 2026 risk assessment notes that people who lose money to crypto scams here have had limited ways to get it back.
Legal tender, regulator, TTSEC, virtual asset service provider (VASP), regulatory sandbox.

2. Which body oversees crypto businesses under the 2025 Act?
The TTSEC oversees the Act and runs the Regulatory Sandbox.
3. Before using a crypto business based in Trinidad and Tobago, what is a sensible step?

Coins like USDT and USDC are designed to stay close to US$1. They are mostly used to move money around, not as investments, so their price should barely change.
