📚 Receiving cryptocurrency is one of the most basic actions when using a crypto wallet.
Just like sending crypto, the process is simple once you understand how it works.
All you need is your public address.
Step 1: Open your crypto wallet
First, open the wallet you want to receive funds in.
Most wallets have a Receive button that allows you to generate your receiving address.
Step 2: Copy your public address
When you click Receive, your wallet will display your public address.
This address is where people can send cryptocurrency to you.
It usually appears as a long string of letters and numbers.
Example:
This is address: bc1p3a8n824de0vf6suhlskefe54sgt6ma9tjqpgr7vxdvvle9q3v0fsgydagz
Most wallets also show a QR code that represents the same address.
This allows someone to scan the code instead of typing the address manually.
Step 3: Share the address with the sender
Next, send your public address to the person who will transfer crypto to you.
You can share it through:
Message
Email
QR code
Since it is a public address, it is safe to share with others.
Step 4: Wait for the transaction to be confirmed
After the sender transfers the cryptocurrency, the transaction will be processed by the blockchain network.
Once the transaction receives enough confirmations, the funds will appear in your wallet.
Depending on the network, this may take anywhere from a few seconds to several minutes.
Important things to remember
🔹 Always use the correct network
🔹 Make sure the address matches the cryptocurrency you want to receive
🔹 Wait for blockchain confirmations
Sending funds to the wrong address or wrong network may cause the funds to be lost.
Simple way to understand it
Receiving crypto is similar to receiving an email.
You simply give someone your email address, and they can send something to you.
In crypto, your public address works the same way.
Anyone can send funds to that address, but only you can access them through your wallet.

📚 Dopo aver creato un portafoglio crypto, una delle cose più importanti da imparare è come inviare criptovaluta a qualcun altro.
Inviare crypto è in realtà piuttosto semplice una volta che comprendi i passaggi di base.
Nella maggior parte dei portafogli, il processo richiede solo pochi secondi.
Ecco come funziona.
Passo 1: Ottieni l'indirizzo pubblico del destinatario
Per inviare criptovaluta, devi prima avere l'indirizzo pubblico della persona a cui vuoi inviare fondi.
Questo indirizzo funge da destinazione per la transazione.
Di solito appare come una lunga stringa di lettere e numeri.

📚 Prima di poter utilizzare le criptovalute, la prima cosa di cui hai bisogno è un portafoglio crypto.
Un portafoglio ti consente di archiviare, inviare e ricevere beni digitali sulla blockchain.
Creare un portafoglio crypto oggi è in realtà molto semplice e richiede solo pochi minuti.
Ecco come funziona solitamente il processo.
1️⃣ Scegli un'app per il portafoglio
Per prima cosa, devi scegliere un'applicazione per il portafoglio.
Alcuni portafogli popolari includono:
Binance Wallet
MetaMask
OKX Wallet
Ogni portafoglio supporta diverse blockchain, ma il processo di configurazione di base è molto simile.

📚 Quando si utilizza la criptovaluta, è necessario un modo per ricevere fondi da altre persone.
È qui che entra in gioco un indirizzo pubblico.
Un indirizzo pubblico è l'indirizzo che le persone usano per inviare criptovaluta al tuo portafoglio.
Funziona in modo simile a un numero di conto bancario.
Puoi condividere in sicurezza il tuo indirizzo pubblico con altri in modo che possano trasferirti criptovaluta.
Il tuo indirizzo pubblico è generato dal tuo portafoglio ed è matematicamente collegato alla tua chiave privata.
Tuttavia, non rivela la tua chiave privata, il che mantiene i tuoi fondi al sicuro.

📚 When you create a crypto wallet, the system usually gives you a list of random words.
This list of words is called a seed phrase.
The seed phrase is one of the most important security elements in crypto.
A seed phrase is a sequence of words that acts as a backup for your crypto wallet.
It can be used to recover your wallet and restore access to your funds if you lose your device.
Most seed phrases contain 12 or 24 words generated in a specific order.
These words represent the private keys that control your wallet.
Here are the key ideas behind seed phrases.
1️⃣ A backup for your wallet
The seed phrase allows you to restore your wallet if your device is lost or damaged.
2️⃣ Usually 12 or 24 words
Most wallets generate a list of words that must be kept in the exact order.
3️⃣ Can recover all wallet keys
Entering the seed phrase into a compatible wallet can restore access to all your funds.
4️⃣ Must be stored securely
Anyone who has your seed phrase can fully control your wallet.
A simple example can help explain this idea.
Imagine losing your phone that contains your crypto wallet.
Without a backup, your funds might be impossible to access.
However, if you wrote down your seed phrase when creating the wallet, you can simply install the wallet again and enter the same words.
The system will recreate your wallet and restore access to your assets.
Because of this, seed phrases must be protected very carefully.
They are essentially the master backup that controls your entire wallet.

📚 When using a crypto wallet, one of the most important concepts to understand is the private key.
Your private key is what truly gives you control over your cryptocurrency.
In blockchain systems, ownership is not determined by your name or identity.
Instead, it is determined by cryptographic keys.
A private key is a secret piece of cryptographic data that allows you to access and control your cryptocurrency.
It is used to sign transactions and prove that you are the owner of the funds.
Anyone who has the private key can move the assets associated with it.
This is why protecting your private key is extremely important.
Here are the key ideas behind private keys.
1️⃣ A secret key that controls your crypto
The private key gives you full access to the cryptocurrency stored in your wallet.
2️⃣ Used to authorize transactions
When you send crypto, the transaction is signed using your private key.
3️⃣ Must always remain private
If someone else gets your private key, they can take your funds.
4️⃣ Cannot be recovered easily
If you lose your private key, you may permanently lose access to your assets.
A simple example can help explain this idea.
Imagine your crypto wallet as a digital vault.
The private key is the only key that can unlock that vault.
If you keep the key safe, your funds remain secure.
But if someone else obtains the key, they can open the vault and take everything inside.
Because of this, keeping your private key secure is one of the most important responsibilities in crypto.

📚 Nell'articolo precedente, abbiamo appreso che un portafoglio crypto consente agli utenti di memorizzare e gestire i propri beni digitali.
Tuttavia, non tutti i portafogli funzionano allo stesso modo.
I portafogli crypto sono solitamente divisi in due categorie principali: portafogli caldi e portafogli freddi.
La principale differenza tra di loro è se sono connessi a Internet.
Questa differenza ha un grande impatto sulla comodità e sulla sicurezza.
Un portafoglio caldo è un portafoglio che è connesso a Internet.
Questi portafogli sono spesso utilizzati tramite app mobili, estensioni del browser o siti web.

📚 To use cryptocurrency, you need a way to store and manage your digital assets.
This is where a crypto wallet becomes essential.
A crypto wallet is a tool that allows users to store, send, and receive cryptocurrency.
Unlike a physical wallet that holds cash, a crypto wallet does not actually store coins.
Instead, it stores the cryptographic keys that give you access to your assets on the blockchain.
These keys allow you to prove ownership and authorize transactions.
Without a wallet, you cannot interact with most blockchain networks.
Here are the key ideas behind crypto wallets.
1️⃣ Stores private keys
A crypto wallet keeps the private keys that control your cryptocurrency.
2️⃣ Allows sending and receiving crypto
You can use a wallet to transfer digital assets to other users.
3️⃣ Connects you to the blockchain
Wallets act as the interface that lets users interact with blockchain networks.
4️⃣ Many different types exist
Crypto wallets can be mobile apps, desktop software, hardware devices, or even paper backups.
A simple example can help explain this idea.
Imagine your cryptocurrency exists in a giant digital vault on the blockchain.
Your wallet does not hold the coins themselves.
Instead, it holds the key that unlocks your section of the vault.
When you send crypto to someone, you are using your key to authorize the transfer.
If you lose the key, you lose access to the vault.
That is why protecting your wallet and private keys is extremely important.
Crypto wallets are one of the most important tools for anyone using cryptocurrency.
They allow users to securely manage their digital assets and interact with blockchain systems.

📚 Not all blockchains are designed in the same way.
Some blockchains are open for anyone to use, while others are restricted to specific participants.
This leads to two main categories: public blockchains and private blockchains.
Both use blockchain technology, but they serve different purposes and operate under different rules.
Understanding the difference helps explain why some blockchains focus on decentralization while others focus on control and efficiency.
A public blockchain is a network that anyone can access and participate in.
Anyone can send transactions, view data, and often help secure the network.
Most well-known cryptocurrencies run on public blockchains.
A private blockchain is a network that is controlled by a specific organization or group.
Only approved participants are allowed to access the system or validate transactions.
Here are the key differences.
1️⃣ Access to the network
Public blockchains allow anyone to join and participate.
Private blockchains require permission from the organization controlling the network.
2️⃣ Level of decentralization
Public blockchains are usually decentralized across many independent participants.
Private blockchains are more centralized and controlled by a specific entity.
3️⃣ Transparency
Public blockchains allow anyone to view transactions and blockchain data.
Private blockchains restrict access to selected participants.
4️⃣ Common use cases
Public blockchains are often used for cryptocurrencies and decentralized applications.
Private blockchains are commonly used by companies for internal systems.
A simple example can help explain this idea.
Imagine two different types of databases.
One is a public online document where anyone can read and contribute information.
The other is a company’s internal database that only employees can access.
Public blockchains work like the open document.
Private blockchains work like the company’s internal system.
Both use similar technology, but their access rules are very different.

📚 One of the most important ideas behind blockchain technology is open participation.
Unlike traditional systems, many blockchains allow anyone to join and use the network.
This concept is known as a permissionless blockchain.
A permissionless blockchain is a network where anyone can participate without needing approval from a central authority.
Users can send transactions, run nodes, or help secure the network without asking for permission.
This open access is a key reason why cryptocurrencies are considered decentralized.
Here are the key ideas behind permissionless blockchains.
1️⃣ Anyone can join the network
Users do not need approval from a company or organization to participate.
2️⃣ Anyone can send transactions
People can transfer assets directly on the network without intermediaries.
3️⃣ Anyone can help secure the network
Participants can run nodes, mine, or validate transactions depending on the blockchain design.
4️⃣ No central authority controls access
The network operates through distributed consensus instead of centralized control.
A simple example can help explain this idea.
Imagine a public park that anyone can enter.
There is no gatekeeper deciding who is allowed inside.
People can visit freely, walk around, and participate in activities.
Permissionless blockchains work in a similar way.
Anyone with an internet connection can access the network and interact with it.
This openness is one of the reasons blockchain technology is considered revolutionary.
It allows financial systems and digital infrastructure to operate without relying on centralized control.

📚 La maggior parte dei progetti blockchain sono costruiti utilizzando un principio chiamato open source.
Il codice sorgente significa che il codice dietro un progetto è pubblicamente disponibile per chiunque possa visualizzarlo, ispezionarlo e utilizzarlo.
Invece di mantenere segreta la tecnologia, gli sviluppatori pubblicano il codice sorgente affinché l'intera comunità possa vedere come funziona il sistema.
Questa trasparenza è una delle idee fondamentali dietro la criptovaluta e la tecnologia blockchain.
Quando un progetto è open source, gli sviluppatori di tutto il mondo possono studiare il codice, suggerire miglioramenti e aiutare a trovare potenziali problemi.

📚 Blockchain networks run based on software and a set of rules that everyone in the network follows.
However, sometimes those rules need to change.
Developers may want to add new features, improve security, or fix problems in the protocol.
When the blockchain software is updated or modified, it can create something called a fork.
A fork in blockchain means the network splits into different versions of the software or the chain.
This happens when participants begin following different sets of rules.
Forks are a normal part of how blockchain systems evolve over time.
Here are the key ideas behind blockchain forks.
1️⃣ A change in the blockchain rules
A fork occurs when developers introduce updates to the blockchain protocol.
2️⃣ The network may temporarily split
Different nodes may run different versions of the software during the update.
3️⃣ Can create new chains
In some cases, a fork leads to two separate blockchains continuing independently.
4️⃣ Helps blockchains evolve
Forks allow communities to upgrade technology or fix problems in the network.
A simple example can help explain this idea.
Imagine a group of people writing a shared rulebook.
One day, some members want to change certain rules.
If everyone agrees, the rulebook is simply updated.
But if there is disagreement, the group may split and create two different rulebooks.
Blockchain forks work in a similar way.
They allow networks to update and adapt, but sometimes they can also create new versions of the blockchain.
Understanding forks helps explain how blockchain systems continue to improve over time.

📚 Quando gli sviluppatori costruiscono applicazioni su una blockchain, non possono testare tutto direttamente sulla rete reale.
Gli errori sulla vera blockchain possono costare denaro reale.
Per risolvere questo problema, le blockchain di solito forniscono due ambienti diversi: testnet e mainnet.
Mainnet è la vera rete blockchain dove avvengono transazioni reali e viene utilizzata la criptovaluta reale.
La testnet è una rete separata progettata per test e sperimentazioni.
Gli sviluppatori utilizzano le testnet per provare nuove applicazioni, testare contratti smart e correggere bug prima del lancio sulla rete reale.

📚 Nell'articolo precedente, abbiamo imparato a conoscere l'EVM, il sistema che esegue smart contract su Ethereum e molte altre blockchain compatibili.
Tuttavia, non tutte le blockchain utilizzano l'EVM.
Alcuni network sono progettati con architetture e tecnologie completamente diverse.
Queste sono conosciute come blockchain non-EVM.
Una blockchain non-EVM è una blockchain che non utilizza la Ethereum Virtual Machine per eseguire smart contract.
Invece, questi network utilizzano i propri ambienti di esecuzione e sistemi di programmazione.

📚 Molte blockchain oggi supportano contratti intelligenti e applicazioni decentralizzate.
Ma affinché queste applicazioni funzionino, la blockchain ha bisogno di un sistema che possa eseguire codice.
Questo è dove entra in gioco l'EVM.
EVM sta per Ethereum Virtual Machine.
È il sistema che esegue contratti intelligenti sulla rete Ethereum.
Puoi pensare all'EVM come al motore che elabora ed esegue il codice delle applicazioni decentralizzate.
Quando un contratto intelligente viene implementato, l'EVM legge il codice ed esegue le istruzioni esattamente come scritto.

📚 Le blockchain sono reti decentralizzate composte da molti nodi.
Tuttavia, la maggior parte degli utenti e delle applicazioni non si connette direttamente a ogni nodo nella rete.
Invece, comunicano con la blockchain attraverso un sistema chiamato RPC.
RPC sta per Chiamata di Procedura Remota.
È un metodo che consente alle applicazioni di inviare richieste a un nodo della blockchain e ricevere dati in cambio.
Attraverso RPC, portafogli, siti web e applicazioni decentralizzate possono interagire con la blockchain.
Possono richiedere informazioni come saldi degli account, storia delle transazioni o inviare nuove transazioni alla rete.

📚 Le blockchain memorizzano enormi quantità di dati.
Ogni transazione, blocco e interazione con contratti smart è registrata permanentemente sulla rete.
Tuttavia, accedere e cercare attraverso questi dati grezzi della blockchain può essere molto lento e complicato.
Le applicazioni hanno spesso bisogno di un modo più veloce per trovare informazioni specifiche.
È qui che gli indicizzatori diventano utili.
Un indicizzatore è uno strumento che organizza e struttura i dati della blockchain in modo che possano essere cercati e accessibili rapidamente.
Invece di leggere l'intera blockchain ogni volta, le applicazioni possono interrogare direttamente i dati indicizzati.

📚 Blockchains are powerful systems for recording transactions and running smart contracts.
However, blockchains have one important limitation.
They cannot directly access information from the outside world.
For example, a smart contract cannot automatically know the price of Bitcoin, the weather, or the result of a sports match.
This is where oracles become important.
An oracle is a service that provides external data to a blockchain.
It acts as a bridge between the blockchain and real-world information.
Oracles allow smart contracts to use data that exists outside the blockchain.
Here are the key ideas behind oracles.
1️⃣ Connects blockchain with real-world data
Oracles deliver external information such as prices, weather data, or event results.
2️⃣ Feeds data into smart contracts
Smart contracts can use this data to automatically execute certain actions.
3️⃣ Enables many blockchain applications
Without oracles, many decentralized applications would not be possible.
4️⃣ Must be reliable and secure
Because smart contracts rely on oracle data, inaccurate information can cause serious problems.
A simple example can help explain this idea.
Imagine a smart contract designed to pay farmers insurance if rainfall drops below a certain level.
The blockchain itself cannot measure rainfall.
An oracle can send weather data to the smart contract.
If the rainfall is too low, the contract automatically releases the insurance payment.
In this case, the oracle provides the real-world information needed for the blockchain to make decisions.
Oracles are essential for many decentralized applications, especially in areas like decentralized finance.
They allow blockchains to interact with real-world events and data.

📚 Blockchain technology has many advantages, such as transparency, security, and decentralization.
However, building a perfect blockchain system is extremely difficult.
This challenge is often described as the blockchain trilemma.
The blockchain trilemma refers to the idea that a blockchain network cannot easily achieve three goals at the same time: decentralization, security, and scalability.
Improving one of these areas often makes it harder to maintain the other two.
Because of this, blockchain developers must carefully balance these three elements when designing a network.
Here are the key parts of the blockchain trilemma.
1️⃣ Decentralization
The network is controlled by many independent participants rather than a single authority.
2️⃣ Security
The blockchain must be resistant to attacks and manipulation.
3️⃣ Scalability
The network should be able to process a large number of transactions quickly.
4️⃣ Trade-offs between the three
Improving one of these factors can sometimes weaken another, making it difficult to optimize all three at once.
A simple example can help explain this idea.
Imagine designing a car that must be extremely fast, extremely safe, and extremely cheap at the same time.
Improving one feature often requires sacrificing another.
For example, making the car safer might increase the cost.
Blockchain developers face a similar challenge.
They must design systems that balance decentralization, security, and scalability without compromising the entire network.
This is why different blockchains focus on different strengths.
Some prioritize security and decentralization, while others focus on improving scalability.
Understanding the blockchain trilemma helps explain many of the design choices in modern blockchain systems.

📚 As more people start using blockchain networks, the number of transactions increases rapidly.
This growth creates an important challenge for blockchain systems.
That challenge is scalability.
Scalability refers to the ability of a blockchain network to handle a growing number of transactions without slowing down or becoming too expensive.
In simple terms, it describes how well a blockchain can support millions of users at the same time.
Many early blockchains were designed with strong security and decentralization in mind.
However, this sometimes makes it harder for the network to process large numbers of transactions quickly.
Here are the key ideas behind scalability.
1️⃣ Transaction speed
Scalability affects how many transactions a blockchain can process per second.
2️⃣ Network congestion
When too many transactions occur at the same time, the network can become slow.
3️⃣ Higher transaction fees
Congestion often causes users to pay higher fees to get their transactions confirmed faster.
4️⃣ Technology solutions are needed
Developers create solutions such as Layer 2 systems, rollups, and sharding to improve scalability.
A simple example can help explain this idea.
Imagine a small restaurant that can serve only a limited number of customers each hour.
If too many people arrive at once, the restaurant becomes crowded and customers must wait longer.
To serve more people, the restaurant may need to expand, add more staff, or open new locations.
Blockchain networks face a similar challenge.
As more users join the network, the system must find ways to process transactions faster and more efficiently.
Scalability is one of the most important problems in blockchain technology.
Many innovations in the crypto industry focus on solving this challenge.
