Family, let's talk about something super important regarding NFTs

Anatomy of an NFT
An NFT (Non-Fungible Token) is basically a unique record on a blockchain (like Ethereum) that represents ownership of a digital asset.

👀 Key parts:
Token (Unique identifier)
Each NFT has a non-repeating ID within a smart contract.
Example: Ape #1234 from BAYC.
Smart contract
It is the code that defines how the NFT works (transfers, royalties, etc.).
In BAYC, it was developed by Yuga Labs.
Metadata
Descriptive information about the NFT:
Name
Image
Attributes (clothing, background, accessories in BAYC)
Normally stored off the blockchain (IPFS or servers).
Digital asset
The associated image, video, or file.
In BAYC: the famous bored monkeys.

⚖️ Copyright vs NFT ownership

This is where many people get confused 👇
🟢 What you DO buy:
Ownership of the token on the blockchain
The right to resell it
In some cases (like BAYC): limited commercial rights
🔴 What you DO NOT always buy:
Full copyright
Total intellectual property of the work
🐵 Example with Bored Ape Yacht Club
With an NFT from Bored Ape Yacht Club:
✔️ You get:
A unique NFT (e.g., Ape #5421)
Rights to use the image commercially
(e.g., create a brand, t-shirts, content)
❗ But:
Yuga Labs remains the original creator
You do not control the entire collection
You cannot prevent others from using THEIR own NFTs

Key idea to understand it
👉 Buying an NFT is more like:
Buying a signed original work
👉 It is NOT the same as:
Buying all rights to the work (total copyright)

Important risks

The file may be hosted off the blockchain
Licenses may change depending on the project
Legal confusion (it is still an evolving area)

🚀 Quick summary
NFT = digital certificate of ownership on blockchain
It has: token + contract + metadata + asset
Ownership ≠ copyright

Family to have it clearer
decentralization is a concept where control and decision-making do not depend on a single entity (like a government, bank, or company), but are distributed among many people or nodes.

In short:
👉 Instead of a single authority commanding, many participants share the power.
Simple example:
Centralized: A traditional bank controls your money.
Decentralized: In Bitcoin, control is distributed among thousands of computers (nodes) around the world.

Why is it important?

🔒 Greater security (there is no single point of failure)
🌍 More transparency
🚫 Less censorship or central control

In the crypto world:
Decentralization is the foundation of technologies like blockchain, where no one has total control, but the network functions thanks to all participants.

FAMILY LET'S TALK ABOUT SOMETHING IMPORTANT

What is the product in a crypto startup?

The product in a cryptocurrency startup is the technological solution that uses blockchain to solve a specific problem.
Unlike traditional startups, these products are usually decentralized, transparent, and token-based.
Example: an app to send money without banks or a video game where users own digital assets.

Types of products in crypto startups

1. 💰 Cryptocurrencies (Digital coins)
They are digital assets primarily designed as a medium of exchange or store of value.
Example: Bitcoin, Ethereum
Use: payments, savings, international transfers

2. 🧠 Blockchain platforms
They are infrastructures where other projects are built.
Example: Ethereum, Solana
Use: creating smart contracts and decentralized apps

3. 🏦 DeFi (Decentralized finance)
Applications that offer financial services without intermediaries.
Example: Uniswap, Aave
Use: loans, savings, trading

4. 🖼️ NFTs (Non-fungible tokens)
Unique digital assets that represent ownership.
Use: digital art, music, video games
Example: digital collectibles or virtual land

5. 🎮 Web3 and metaverse
Products focused on decentralized digital experiences.
Use: play-to-earn games, virtual worlds
Example: Decentraland

6. 🔐 Infrastructure and tools
Services that enable the ecosystem to function.
Example:
Wallets like MetaMask
Oracles like Chainlink

🚀 Conclusion
The product in a crypto startup is not just an app, but a digital ecosystem based on blockchain.
Each type serves a different role:
Some act as money 💰
Others as platforms 🧠
Others as financial services 🏦
And others as digital experiences 🎮

👉 The key is to understand what problem each product solves and how it uses decentralization to innovate.

Family A node is a point within a network responsible for receiving, sending, and validating information.
In the context of blockchain (like Bitcoin), a node is a computer or device that is connected to the network and performs key functions.

Main functions of a node:
Verify transactions: checks that the operations are valid.
Store information: keeps a copy of the history (the blockchain).
Transmit data: shares blocks and transactions with other nodes.
Keep the network secure: helps prevent fraud and manipulation.

In short:
A node is like a "guardian" of the network: it confirms that everything is functioning correctly and maintains the trust of the system.

FAMILY 👀 with this new robbery modality in this crypto world

What is address poisoning?
Address poisoning is a type of attack in blockchain where an attacker tries to deceive the user into sending funds to a wrong address, making it look legitimate.

How does it work?
The attacker creates a fake address
Generates a wallet with initial and final characters very similar to an address that you already use.
Sends a small transaction (or even 0 tokens)
This is done so that the fake address appears in your transaction history.
User confusion
When you want to send money, you see that address in your history and believe it is trustworthy (because you have already “interacted” with it).
Fatal error
You copy that fake address and send funds… which end up in the hands of the attacker.

Why does this attack work?
Addresses in blockchain are long and difficult to memorize
Many people only check the first and last characters
There is too much trust in transaction history

Main risks
Total loss of funds (transactions in blockchain are irreversible)
Difficult to detect if you don’t pay attention
Can affect both beginners and experienced users

How to protect yourself?
Always verify the complete address, not just part of it
Store frequent addresses in a secure list (whitelist)
Avoid copying addresses from history without reviewing
Use wallets with security features (alerts or tags)
First, make a test transaction with a small amount of money

💡 Conclusion
Address poisoning does not hack the blockchain, but exploits human behavior. It is a social engineering attack within the crypto world

FAMILY LET'S TALK ABOUT AN INTERESTING TOPIC
🌐 Legal regulations for Web3 startups in Latin America
Web3 startups (blockchain, cryptocurrencies, NFTs, DeFi) in Latin America operate in a developing and fragmented legal environment, meaning there is no single uniform law for the entire region.

⚖️ 1. Regulatory framework under construction
Many countries are still creating or adjusting laws for crypto assets.
This generates uncertainty but also opportunities for innovation.
👉 Example: some countries have specific laws (like exchanges or crypto remittances), while others only apply traditional financial regulations.

🏦 2. Financial regulation and compliance
Startups must comply with rules similar to fintech:
KYC (Know Your Customer) → identify users
AML (Anti-Money Laundering) → prevent financial crimes
Regulation of virtual asset service providers (VASP)
👉 This is key if they handle cryptocurrencies or payments.

🪙 3. Legal classification of tokens
Governments can classify tokens as:
Securities (similar to stocks)
Digital assets
Means of payment
👉 This defines which regulations to apply (financial, tax, etc.).

💼 4. Legal structure of the startup
Many Web3 startups in Latam:
Are established in “crypto-friendly” countries
Use hybrid models (traditional company + DAO)
👉 Choosing the right jurisdiction is a strategic decision

💸 5. Taxation
Cryptocurrencies are often subject to taxes:
Capital gains
VAT or taxes on digital services
There are still legal gaps in several countries.

📊 6. Current trend
Regulation is growing and has driven crypto adoption in the region.
Latin America already has millions of users and an expanding ecosystem.

Family that is a block here has a brief and clear explanation:

A block is a unit of information that is part of a blockchain. Basically, it is like a “box” where transaction data is stored.
Each block contains three main elements:

1. Data: information of the transactions (for example, transfers of cryptocurrencies like Bitcoin).
2. Hash: a unique code that identifies the block, generated using cryptographic functions like SHA-256.
3. Hash of the previous block: this connects one block to another, forming a secure chain.
🔗 Thanks to this structure, if someone tries to modify a block, it changes its hash and breaks the entire chain, which makes the system very secure.

In summary:
👉 A block is like a page of a digital book where transactions are recorded, and all the pages together form the blockchain.
If you want, I can make a diagram or an image for you to understand it better 👀

Blockchain is a technology that functions as a digital, distributed, and secure ledger, where transactions or data are stored in a decentralized manner.

Instead of being on a single server, the information is copied and synchronized across thousands of computers (nodes) around the world.

Each set of data is stored in a “block,” which is linked to the previous one forming a chain (hence the name “blockchain”). Once a block is registered, it is practically impossible to alter it without modifying the entire chain, which provides security and transparency.

FAMILY TO UNDERSTAND A LITTLE BETTER THE CONVERT FUNCTION IN BINANCE

What is “Convert” in Binance?
The Convert option is a tool that allows you to exchange one cryptocurrency for another quickly and easily, without the need to use charts or advanced trading.

How does it work?
You select the currency you have (for example: Bitcoin).
You choose the currency you want to receive (for example: USDT).
You enter the amount.
Binance shows you a real-time conversion rate.
You confirm and that's it

Advantages
Very easy to use (ideal for beginners)
No trading knowledge required
Almost instant conversion
No visible fees (although there is a small margin in the price)

Disadvantages
You cannot choose the price (like in trading)
It may be a little less profitable than using the spot market

In a nutshell
The Convert function is perfect if you want to make quick changes between cryptocurrencies without complicating things, but if you're looking for better prices, traditional trading might be more convenient.

Family Growth of NFTs and their impact during the pandemic
NFTs (Non-Fungible Tokens) are unique digital assets that use blockchain technology, especially networks like Ethereum, to ensure authenticity and ownership.
During the COVID-19 pandemic (2020–2022), NFTs experienced explosive growth due to several key factors:

1. Accelerated Digitalization
The lockdown forced millions of people to move their activities to the digital world. This boosted interest in:
Digital art
Virtual collectibles
Blockchain games
NFTs became a new form of interaction and ownership on the internet.

2. New Sources of Income
Many artists, musicians, and creators lost traditional income (events, galleries, concerts). NFTs provided an alternative to:
Sell art directly without intermediaries
Receive automatic royalties from resales
An iconic case was the artist Beeple, who sold an NFT artwork for 69 million dollars, marking a before and after in the market.

3. Rise of the Crypto Market
The growth of cryptocurrencies like Bitcoin and Ether during the pandemic increased interest in digital assets, including NFTs.

4. Expansion in Video Games and the Metaverse
Platforms like Decentraland promoted the use of NFTs in:
Virtual land
Avatars
Digital objects
This helped solidify the concept of a decentralized digital economy.

5. Impacts and Challenges
Although the growth was impressive, problems also arose:
Excessive speculation
Scams and fraudulent projects
Environmental impact (due to energy consumption)

Conclusion
The pandemic acted as a key accelerator for NFTs, driving their global adoption. Although the market has had ups and downs, NFTs marked the beginning of a new era in digital ownership and the creative economy.

Let's discuss something important that we need to know
What is a Merkle Tree?
A Merkle Tree (or Merkle tree) is a data structure used in cryptography and blockchain to verify information quickly and securely.
It is based on hash functions like SHA-256.

Basic idea
Imagine you have a lot of data (for example, transactions). Instead of verifying one by one, the Merkle tree allows you to summarize everything into a single value called:
* Merkle Root

How does it work?
You take the data (transactions)
You apply a hash to each one
Then you combine the hashes in pairs and hash them again
You repeat until you have a single final hash

Why is it important?

1. Quick verification
You can check if a piece of data belongs to the set without reviewing everything

2. Security
If someone changes a single transaction → it changes the entire tree

3. Efficiency
Saves time and resources (key in blockchain)
₿ Use in blockchain
In networks like Bitcoin:
Each block contains a Merkle Root
This allows for transaction verification without downloading the entire block
It is key for so-called lightweight nodes (SPV)

Practical example
If you want to verify that a transaction exists:
You do not need all transactions
You only need:
The hash of your transaction
Some hashes from the tree (verification path)
This is called Merkle Proof

In short
👉 A Merkle Tree is like a “smart summary” of a lot of data
👉 It allows for secure, quick, and efficient information verification
👉 It is fundamental in blockchain and cryptography

What is SHA-256?

SHA-256 (Secure Hash Algorithm 256 bits) is a cryptographic hash function that is part of the SHA-2 family, designed by the National Security Agency.
Its main function is to convert any type of information (text, files, data) into a unique code of 256 bits (64 hexadecimal characters).

How does it work?
It takes an input (for example: "Hello world").
Applies a complex mathematical process.
Generates a fixed hash, regardless of the size of the original message.

Main characteristics
Deterministic: The same input always produces the same result.
Irreversible: The original data cannot be obtained from the hash.
Unique: A small change in the input generates a completely different hash.
Secure: Very difficult to find two inputs with the same hash (collisions).

What is it used for?
Blockchain (like Bitcoin)
It is used to secure blocks and transactions.

Computer security
Protection of passwords and data verification.

File integrity
Check that a file has not been modified.

Importance
SHA-256 is fundamental in today's digital world because it ensures security, trust, and transparency, especially in technologies like blockchain and cryptocurrencies.

What are NFTs in NEAR Protocol?
In NEAR, NFTs (Non-Fungible Tokens) are unique digital assets (art, music, video games, etc.) that exist on the blockchain. Each NFT has a unique identifier and cannot be exchanged equivalently like a cryptocurrency.

NEP-171 Standard (Basis of NFTs)
This is the main standard for creating NFTs in NEAR (like ERC-721 in Ethereum).

What does it define?
How to create (mint) NFTs
How to transfer them
How to query them
Unique identification (token_id)

Key functions:
nft_mint → Create an NFT
nft_transfer → Send NFT to another account
nft_token → View information about an NFT
👉 Basically, NEP-171 is the heart of NFTs in NEAR.

NEP-177 Extension (Metadata)
This standard complements NEP-171 by adding visual and descriptive information.

What does it include?
NFT name
Description
Image (URL or IPFS)
Attributes (rarity, characteristics, etc.)

👉 NEP-177 makes your NFT “visible and attractive,” not just an ID.

How to use them together?
You create the contract with NEP-171
You add metadata with NEP-177
You mint the NFT with included data

Quick summary
NEP-171 → Functionality (create, transfer NFT)
NEP-177 → Appearance (name, image, data)
Both together create a complete NFT in NEAR

Hash functions are cryptographic algorithms that transform any type of data (text, files, numbers) into a fixed string of characters called a hash or digital summary.

Main characteristics:
Deterministic: the same data always generates the same hash.
Irreversible: the original data cannot be obtained from the hash.
Fast to calculate: they generate results in a short time.
Sensitive to changes: a small change in the data produces a completely different hash.
Collision-resistant: it is very difficult for two different data to generate the same hash.

What are they used for?
Verify data integrity (detect if something has been modified).
Protect passwords (they are stored as hash, not in plain text).
In blockchain like Bitcoin, they ensure the structure of blocks through algorithms like SHA-256.
