What is bitcoin and how it works
Bitcoin is a digital currency launched in 2009 by an anonymous person known under the pseudonym Satoshi Nakamoto . I have attached below the official document underlying this cryptocurrency
Unlike traditional money issued by governments, Bitcoin works without the need for banks or intermediaries, it is an ecosystem. There is no central bank that guarantees this cryptocurrency or a private company. When you send Bitcoin to someone, your transaction is confirmed in the Bitcoin blockchain. If you are curious what the blockchain is then this article is for you " what is blockchain? Simple explanation "
Here's what you need to know about it:
- Bitcoin exists only in electronic form. No physical coins or banknotes.
- Is not controlled by any central bank or organization. Is completely independent.
- The identity of the users is anonymous, but all transactions are public and can be checked in blockchain.
- Bitcoin existed in limited quantity. Only 21 million bitcoin will ever be created, which makes it a limited and valuable resource. Today (March 7, 2025) there is a total of 19.832,874 BTC in circulation, Bitinfocharts
- Bitcoin transactions are carried out directly between users (from person to person) by a technology called blockchain.
What is blockchain technology
Blockchain is a digital register divided into blocks, each block containing information (such as transactions). The blocks are connected to each other in chronological order, forming a chain - hence the name "blockchain". Decentralization, security and transparency are three key aspects of blockchain technology. This is why:
Decentralized architecture
Blockchain eliminates the need for third-party parts, such as banks, offering more control to individual users. Results:
- The transactions are faster and cheaper, because there are no intermediaries.
- Power and decisions are not concentrated in one place, reducing the risk of corruption.
Security and trust
Because each new block is related to the previous blocks, the data change becomes extremely difficult, almost impossible.
Examples:
- In the financial field, blockchain can eliminate fraud.
- In the field of health, it can keep data of safe patients and protected by unauthorized access.
Transparency
In blockchain technology, transparency refers to the ability to view and check all transactions and data stored on the network. Each transaction is checked by several nodes in the network before being added to the blockchain.
For example:
- Organizations can use blockchain to record and track donations, creating a reliable environment for donors.
- Companies can transparent the supply chains, from raw materials to the final product.
- Another example of use was the transmission of information regarding the vote of citizens in Romania. More about this example you can read on the Sts statement
In short, blockchain records all Bitcoin transactions and keeps them safe, transparent and accessible to anyone who wants to check them.
Bitcoin wallets and addresses
Bitcoin wallets play an essential role in cryptocurrency transactions, offering total safety and control over your funds. Whether you are an beginner investor or an experienced enthusiast, understanding of types of wallets and bitcoin addresses is essential to protect your investments. Next, you will find out:
- What is a bitcoin wallet and what you need it
- Types of wallets available (hardware, software, online)
- Bitcoin addresses and how to choose the safest option
Let's discover together everything you need to know!
What is a bitcoin wallet and why is it needed
A bitcoin wallet is an app or device that you have access to your cryptocurrencies. Think of the Bitcoin wallet as a digital bank account. It allows you to receive, store and send Bitcoin, but without depending on a central institution, such as a bank.
Why do you need a bitcoin wallet?
1. Total control: You have absolute control over your funds, without intermediaries.
2. Maximum security: Protection of your coins against hackers and other threats is a priority.
3. Accessibility: The transactions are fast and easy to do, no matter where you are.
The Bitcoin wallet works using a public key (the address with which you receive funds) and a private key (used to access the respective funds). It is vital to keep the key private in a safe place.
Types of bitcoin wallets
There are several types of bitcoin wallets, each with specific advantages and disadvantages. The choice depends on your needs and the level of security desired.
Wallets or cryptocurrency wallets can be:
- Hot Wallet (Internet connected wallet)
- Cold Wallet (wallet that is not connected to the Internet)
Types of Bitcoin wallets in Romania
1. Hardware (Cold Wallet) wallets
Hardware wallets are physical devices that store offline private keys. They work disconnected from the Internet, which is why they are also called Cold Wallet (only when you make a transaction you are temporarily connecting to the computer or smartphone).
Advantages:
- Extreme Security: Because they are offline, they are almost impossible to hack.
- Compatibility: Works with various software applications.
Disadvantages:
- Costs: A good hardware wallet can cost between 50 and 150 EUR.
- Limited Access: You must have your physical device to perform transactions.
Popular examples: Ledger Nano S , Trector model T.
2. Software wallets
These wallets are applications installed on your mobile or computer and are ideal for daily transactions. Software wallets are also divided into two main categories: Hot Wallets and Cold Wallets, the Hot Wallets being permanently connected to the Internet.
You can find out more by reading the article: What is a bitcoin wallet?
Advantages:
- Accessibility: Quick and easy to use.
- FREE: Most are either free or have low costs.
Disadvantages:
- Reduced safety: Being connected online, they are more exposed to hacks.
Popular examples: Exodus , Electrum , Trust Wallet .
3. Paper Wallets wallets
Paper wallets are pieces of paper on which private and public keys are written. Being 100% offline are protected against hacks. However, they are not the best version of cryptocurrency storage, because damage or loss of paper can lead to complete loss of funds.
Types of Bitcoin addresses and their importance
Bitcoin addresses are a unique string of letters and numbers, which allow users to send and receive cryptocurrencies. Not all addresses are the same. Each type has its own characteristics.

Lightning Network: Bitcoin scaling for fast transactions
Bitcoin scalability has always been a major challenge for its global adoption. With only 7 processed transactions per second on the main blockchain, compared to tens of thousands processed by networks such as Visa, the use of Bitcoin for daily transactions may seem limited. The solution? Lightning Network , a technology that promises to solve this problem.
What is Lightning Network?
Lightning Network is a "secondary layer" for Bitcoin, designed to allow faster and cheaper transactions. Instead of relying exclusively on the main blockchain (Mainnet), this network manages the "off-chain" transactions, thus reducing the pressure on the main blockchain.
Basically, Lightning Network allows users to transfer Bitcoin directly through private payment channels that do not require each transaction on blockchain. This makes the system faster, cheaper and more scalable.
The problem of scalability
Let's think about the differences between bitcoin and traditional payments:
- Visa can process about 4000 transactions per second , with a peak of up to 65,000.
- Bitcoin , however, processes only about 7 transactions per second due to block size limitations (1MB).
This difference makes the use of Bitcoin for frequent and small transactions, but Lightning Network solves this obstacle through a smarter and fastest approach.
How does Lightning Network work?
The operation of Lightning Network is based on the idea of bilateral payment channels . Here is the process explained step by step:
1. Opening a payment channel
To start, two parties involved in a transaction (eg, a customer and a cafe) open a payment channel in the Lightning network. This process involves:
- The deposit of a bitcoin amount in a multisignature address, which requires the approval of both parties to access the funds.
- Registering this action on the main blockchain to ensure transparency.
Example:
Dragoș deposits 0.05 BTC in a payment channel for his favorite cafe. Each time you buy coffee, the relevant amount is deducted from this channel, without registering the transaction on blockchain.
2. Transactions through the channel
Once the channel is open, multiple transactions can be performed:
- If a coffee costs 0.001 BTC , the balance sheet indicates the transfer of this amount from Dragos's balance to the balance of the cafe.
- The transaction is digitally signed by both sides and kept in the channel.
This method allows thousands of transactions without loading the main network.
3. Closing the channel
When the channel is no longer used, the two parts close the channel using the last "balance sheet" signed. It is transmitted to the main blockchain, and the miners validate the transactions and release the funds according to the balance.
In this process, only two transactions are recorded on the main blockchain:
- Creating the channel.
- Closing the channel.
The advantages of Lightning Network
Lightning Network brings multiple benefits that improve scalability and accessibility of bitcoin. These include:
1. Reduction of commissions
"Off-chain" transactions require minimal commissions, as it does not involve permanent registration on the main blockchain.
2. Quick transactions
Payments are processed almost instantly, thus eliminating delays associated with confirmations in blockchain.
3. Increased scalability
By downloading the main blockchain, Lightning Network can handle an almost unlimited number of simultaneous transactions.
4. Improved safety
The funds are stored in multisignature addresses, which means that only the parties involved can access the balance, with mutual consensus.
5. Payments through intermediaries
It is not necessary to open direct payment channels with each user. Lightning Network can transfer funds through intermediaries, which simplifies the process.
A practical example: the network of intermediaries
Suppose Ileana wants to buy a coffee from the same cafe as Dragos, but she does not have a direct payment channel with it. It can send Mihai's funds, which sends them further to the cafe through its existing channel.
Lightning Network finds the most effective payment route, using as few intermediaries and commissions as small as possible.
How can you use Lightning Network?
Lightning Network is already implemented and used by numerous wallets and platforms. Among the most popular applications are:
- Muun Wallet : Provides fast and cheap transactions through Lightning Network.
- Bluewallet and other Lightning-Friendly wallets.
To start, download a compatible wallet and charge it with bitcoin. From there, the configuration of the payment channels becomes a simple and fast process.
Why is Lightning Network essential for Bitcoin?
Lightning Network is a crucial step in the future Bitcoin, turning it from a value storage system into an accessible and usable means for daily transactions. With each open channel, the network becomes stronger, more scalable and more relevant to an increasingly digitized world.
