1. Blockchain
A shared digital record that stores confirmed actions under a defined set of rules.
Crypto explained
Understand crypto – step by step.
No prior knowledge is required. You start with the basics and build from there: What is a blockchain, how does a wallet work, what are coins and tokens, and what do smart contracts do?
Then you move on to security, prices, token distribution and how to judge claims made by crypto projects for yourself. The language stays as simple as possible and as precise as necessary.
Goal of this page:
You do not need to know every technical detail. You should understand what the main terms mean,
what risks sit behind them and which claims can actually be supported by evidence.
The starting point
Crypto in 60 seconds
A blockchain is a shared digital record. It can record confirmed actions under fixed rules so that other people can check them later. Cryptocurrencies and tokens use these networks to move digital value or provide specific functions.
2. Wallet
A crypto wallet manages the keys you use to approve actions connected to a blockchain address.
3. Coin or token
Digital assets that exist on a blockchain network. How they are created and what rules apply can differ.
4. Smart contract
A program on a blockchain that can carry out rules defined in advance.
One sentence to remember:
The blockchain records actions, a wallet approves them, coins and tokens are digital assets,
and smart contracts can carry out predefined rules.
One example for everything that follows
Anna sends Max 10 tokens.
Anna approves the instruction in her wallet. The blockchain network checks whether the transfer follows its rules. If it is confirmed, the blockchain records the result.
It can then be checked that the transfer happened. That does not automatically prove why Anna paid, who controls Max's address or what happened outside the blockchain afterwards. You will learn about fees, smart contracts and technical checking tools in the topics that follow.

13 topics – in an order that works without prior knowledge
Each card explains the essential idea first. “Simple and detailed explanation” then adds an example, useful terms, common limits and a short takeaway. Industry terms are introduced only when they help you understand or use the concept in practice.
01 — What does “crypto” mean?
“Crypto” is an umbrella term for digital assets and applications that use cryptography and blockchain technology. Bitcoin is one example, not the whole category.
The first step is being able to tell a blockchain, wallet, coin, token and smart contract apart.
02 — How does a blockchain work?
A blockchain is a shared digital record. It stores confirmed actions according to a network's defined rules.
This can make certain digital actions checkable later. Visibility alone does not mean an action was sensible or safe.
03 — Wallets, addresses and keys
A wallet manages the keys you use to approve actions for a blockchain address. The assets themselves are not stored inside the wallet like files.
The key question is who controls the secret keys: you or a provider.
04 — Coins and tokens
Coins and tokens are digital assets. A coin belongs directly to a blockchain network; a token is created through a smart contract on an existing network.
The label alone tells you nothing about usefulness, security, control or economic value.
05 — Networks and fees
Blockchain networks are separate systems. A transaction has to run on the correct network, and processing it may require a network fee.
You will also learn the difference between live networks, test networks and the terms Layer 1 and Layer 2.
06 — Programs on a blockchain
A smart contract is a program on a blockchain. It can carry out predefined rules for tokens, permissions or other processes.
What matters is not only what the code does, but also whether specific people have special rights to change it.
07 — Using crypto safely
If you approve transactions and manage keys yourself, you also carry more responsibility. Wrong addresses, fake websites or overly broad permissions can have immediate consequences.
Basic rule: never share secret keys and check the destination, network, amount and permissions before approving anything.
08 — Understanding price and trading
A displayed token price is a current trading price. It does not mean any amount can be sold at exactly that price.
Liquidity, trading volume, distribution and future token releases can be just as important when you assess the market.
09 — Token supply and distribution
This is about how many tokens exist, who receives them, when they become available and whether more can be created later.
The crypto industry often calls this economic structure “tokenomics.”
10 — What can a token be used for?
A token can have specific functions inside a project, such as providing access to a feature or allowing participation in a vote.
An announced function is not the same as a function that already exists and can actually be used.
11 — Who is allowed to decide?
In many crypto systems, specific people or groups can hold special rights. The key question is who can change rules, move funds or trigger emergency actions.
The industry often describes the organization of these decision rights as “governance.”
12 — Checking claims and evidence
Transparency makes information visible. Checking a claim means going further and asking whether that information actually supports the specific claim.
The three core questions are: What is visible? What does it prove? What remains unproven?
13 — What a blockchain cannot prove
A blockchain can provide strong evidence for digital actions. By itself, it cannot prove what actually happened outside the blockchain.
Movement of funds, decision authority and a real-world result therefore need different kinds of evidence.
Understand first. Then check.
Crypto terms are not quality guarantees.
Words such as “transparent,” “decentralized,” “locked” or “audited” can describe useful properties. None of them proves the underlying claim by itself. What matters are understandable rules, permissions and evidence that fits the claim.
“Transparent”
What information is actually visible? Which addresses, rules and actions can be checked, and which important information is still missing?
“Decentralized”
Who holds special rights? Who can change rules, move funds or trigger emergency actions? Different parts of a system can distribute control in different ways.
“Locked”
What is locked, for how long, and can a person or special role change or bypass the restriction?
“Audited”
Who reviewed it, what exactly was reviewed and which version of the system did the review cover? An audit can reduce risk, but it is not a security guarantee.
Checking principle: For important claims, ask three questions: What is visible? What does it prove? What remains unproven?
Apply what you learned
The fundamentals are here. GFC-specific evidence belongs in the Transparency Portal.
“Crypto Explained” covers general concepts independently of any single project. GFC-specific claims, technical references and the current development status are therefore documented separately.
This keeps a clear line between what the technology can do in general and what GFC has actually published, tested or supported with checkable evidence at a particular point in time.
Current status:
GFC is in development. A public pilot is documented on Base Sepolia, which is a test environment.
There is currently no public GFC mainnet token, no active public presale and no published public purchase process. Nothing is being sold at this time.
