Learning the friendly way

Trying to reach someone in the United States from another country? The USA country code is simpler than you might think, but getting the format wrong can leave you staring at a phone that just won't connect. 

Whether you're an expat missing home, a business professional scheduling that important conference call, or a traveller trying to sort out logistics, understanding how to dial the US correctly will save you time, money, and a fair bit of frustration.

The United States shares its country code system with Canada and several Caribbean nations, which creates some unique considerations you won't find with other countries. Let's break down exactly what you need to know to connect successfully every time.

What is the country code for the USA?

The USA country code is 1. You might also see it written as 001, but these represent the same thing - both are correct ways to reference America's international dialing code.

This "1" code covers not just the United States, but also Canada and many Caribbean countries as part of the North American Numbering Plan (NANP). When dialling from overseas, you'll use this single digit followed by the area code and phone number.

Here's what a complete international call looks like: Your country's exit code + 1 + area code + phone number

Example from the UK to New York: 00-1-212-555-0123

How to call the USA from abroad: step-by-step

International calling might seem complicated, but it follows the same pattern worldwide. Here's your roadmap:

Step 1: Find your country's exit code

Different countries use different codes to "exit" their domestic system:

• UK, most of Europe: 00
• Australia: 0011
• Japan: 010
• Brazil: 0015
• China: 00

Step 2: Add the US country code (1)

After your exit code, always dial 1 for the United States.

Step 3: Include the area code

US area codes are always three digits. Don't skip this, even mobile numbers need their area code when calling from abroad.

Step 4: Dial the local number

US phone numbers have seven digits after the area code.

Complete format examples:

• From UK to Los Angeles: 00-1-310-555-7890
• From Australia to Miami: 0011-1-305-555-2468
• From Japan to Chicago: 010-1-312-555-9876

Most modern phones let you replace your country's exit code with +, making it even easier: +1-310-555-7890

What are the area codes in the USA?

Area codes are three-digit numbers that identify specific geographic regions within the US. Originally designed when operators manually connected calls, they now help route your call to the right part of the country.

Each major city typically has multiple area codes due to population growth and the explosion of mobile devices. Here are the most commonly searched codes:

Pro tip: Mobile numbers keep their original area code even when people move, so a 212 number doesn't guarantee someone is actually in Manhattan.

How to format a US phone number correctly

US phone numbers follow a standard structure, but the formatting changes depending on how you're using them:

Domestic US format:

(XXX) XXX-XXXX or XXX-XXX-XXXX Example: (555) 123-4567 or 555-123-4567

International format:

+1-XXX-XXX-XXXX Example: +1-555-123-4567

When writing for international audiences:

Always include the country code (+1) and use hyphens or spaces for clarity. Avoid parentheses around area codes in international contexts - they can confuse overseas callers.

The total length is consistent: 10 digits after the country code, with the first three being the area code.

Common mistakes when calling the US

Even experienced international callers stumble over these frequent errors:

Forgetting the exit code: Dialing 1-555-123-4567 instead of 00-1-555-123-4567 (from most countries)

Skipping the country code: Assuming you can dial just the area code and number

Wrong exit code: Using 011 (US/Canada exit code) when calling FROM other countries TO the US

Missing area codes: Trying to dial just the seven-digit local number

Carrier restrictions: Not realising your phone plan blocks international calls by default

Quick fix checklist:

Before giving up on a failed call, verify you've included: your country's exit code, the number "1", the complete area code, and all seven digits of the local number.

Can you call the USA for free?

Yes, just not the traditional way. Here are several alternatives that cost nothing beyond your internet data:

Internet-based calling options:

WhatsApp: Popular worldwide, works for both voice and video calls to US numbers 

FaceTime: Perfect if both parties use Apple devices  

Google Voice/Google Meet: Free calling between accounts 

Facebook Messenger: Voice and video calling through the app 

Viber: Good call quality with wide device compatibility

What you need:

• Reliable internet connection (Wi-Fi preferred to avoid data charges)
• Both parties must have the same app installed
• Account setup on your chosen platform

The reality check:

While these services are "free," call quality depends entirely on internet speed. For important business calls, traditional phone service might be more reliable, but for casual conversations, internet calling is hard to beat.

Best time to call the USA from abroad

The United States spans multiple time zones, which affects when your call will be welcomed:

US time zones (west to east):

• Pacific Time: California, Nevada, Washington
• Mountain Time: Colorado, Arizona, Utah
• Central Time: Texas, Illinois, Louisiana
• Eastern Time: New York, Florida, Georgia

Timing recommendations:

For business calls, target 9 AM to 5 PM in the recipient's time zone, Monday through Friday. Avoid US federal holidays like Independence Day, Thanksgiving, and Christmas.

For personal calls, evenings (6-9 PM local time) often work well, as do weekend afternoons. Avoid very early mornings or late nights unless you know the person's schedule.

Cost considerations: Some international carriers offer cheaper rates during off-peak hours. Check with your provider about specific timing for better rates.

Use online time zone converters to double-check before important calls - there's nothing more embarrassing than waking someone up at 3 AM because you miscalculated.

Emergency numbers in the USA

If you're visiting the US or need to help someone in an emergency, these numbers work from any phone:

Primary emergency services:

911: Police, fire department, ambulance (works from mobile phones even without service)

Specialised crisis lines:

988: Suicide & Crisis Lifeline (available 24/7) 

1-800-222-1222: Poison Control Center 

1-800-656-4673: National Sexual Assault Hotline 

211: Community services and local resources

Important Notes:

Emergency services are free from any phone, including payphones and mobile devices without active service. International visitors can use these numbers just like US residents.

Wrapping up your US calling success

Calling the United States boils down to a simple formula: your exit code + 1 + area code + seven digits. Master this pattern, and you'll connect successfully whether you're calling a New York skyscraper or a small-town diner in Kansas.

If you’re interested in staking Ethereum, you came to the right place. The largest liquid staking protocol in the crypto ecosystem, trusted by thousands of ETH holders who want rewards without losing liquidity, has a name: Lido DAO.

Ethereum's Leading Liquid Staking Protocol

How does it work? 

Lido DAO is a decentralized autonomous organization that provides a liquid staking solution on the Ethereum 2.0 blockchain as well as other Proof of Stake (PoS) platforms like Solana (SOL), Polygon (MATIC), Polkadot (DOT), and Kusama (KSM).

Instead of locking up funds, users stake ETH and receive stETH tokens in return, which represent their staked ETH plus accrued rewards. This allows users to continue trading, lending, or using their tokens across DeFi while still benefiting from staking yields. Since launching in 2020, Lido DAO has grown to manage more than $40.33B in Total Value Locked (TVL), with staking rewards currently averaging an annual percentage rate (APR) of 2.71%. The protocol is governed by holders of the LDO token, ensuring community-driven decision-making.

‍

Where did it come from?

Lido DAO was co-founded by Kasper Rasmussen and Jordan Fish, also known as CryptoCobain. Behind the Lido DAO are a number of individuals and organizations that are well-regarded within the DeFi space. Since its inception in December 2020, shortly after ETH 2.0's release, the platform has been overseen by the Lido DAO, with several key members including Semantic VC, Chorus, ParaFi Capital, P2P Capital, Libertus Capital, Terra, StakeFish, Bitscale Capital, StakingFacilities, and KR1. Several of the highly esteemed angel investors include Stani Kulechov of Aave, Banteg of Yearn, Will Harborne of Deversifi, Julien Bouteloup from Stake Capital, and Kain Warwick from Synthetix.

Since then, Lido DAO has gained an impressive reputation for its liquid staking capabilities, and now boasts over $13 billion in staked assets. Its core focus is on Ethereum, yet its horizons are expanding to other blockchain networks including Terra and Solana, both of which launched staking capabilities in 2021, as well as several other layer 1 PoS blockchains.

Liquid Staking Made Simple

Lido DAO simplifies staking into a three-step process: deposit ETH, receive stETH, and start earning rewards automatically. When a user deposits ETH, the protocol delegates funds to a decentralized network of professional node operators. There are over 800 node operators worldwide, who manage validation securely and efficiently.

The stETH tokens received are liquid ERC-20 assets whose value increases over time as rewards accumulate. With one-click staking through Lido DAO’s interface, users can skip the hassle of running their own validator while enjoying a 98.2% validator performance.

How validator rewards are earned from staked assets

So, in order to stake ETH, become a validator and earn rewards for validating payments on the Ethereum platform, users are required to stake a minimum of 32 ETH tokens. What if I don’t have 32 ETH? You may ask. To bypass this minimum requirement and still earn rewards, Lido DAO allows users to stake a fraction of this amount and earn a proportionate amount of block rewards.

Users will then deposit ETH into the Lido smart contract and receive the same number of stETH. These tokens are minted once the funds have been received and are burned when the users withdraw their original ETH. The staked funds will then be distributed to the validators on the Lido network and deposited into the Ethereum Beacon Chain from where they will be secured in a smart contract.

The Lido DAO will then assign, onboard, support and enter the validators' addresses to the smart contract registry before being given a set of keys for the validation. All ETH that users have deposited on the Lido platform will be split into groups of 32 ETH among the active Lido node operators who will use this public validation key to validate transactions. The block rewards will then be shared proportionately.

Notably, this distribution process of sharing staked assets eliminates single-point-of-failure risks common among single-validator staking.

‍

Your Liquid Staking Asset

At the center of Lido DAO’s system is stETH, the tokenized representation of staked ETH. stETH trades on major exchanges, offering deep liquidity and integration with several DeFi protocols. Staking rewards are earned automatically, so users never need to claim manually.

Users can stake any amount of ETH to the Beacon Chain without having to deal with lock-up requirements or withdrawal delays. This way Ethereum holders can enjoy both liquidity and yield simultaneously. For providing this staked ETH service, a 10% fee is collected by Lido for each process.

DeFi Integration Opportunities

For advanced users, stETH unlocks a wide range of yield optimization strategies. Lending platforms like AAVE accept stETH as collateral, while liquidity pools on CURVE and UNISWAP offer additional yield opportunities. Leveraged staking strategies also allow users to compound rewards further.

Proven Security

Security and safety are central to Lido DAO's success. Since the beginning, the protocol has undergone a dramatic array of independent audits, conducted by top-tier firms including Statemind, Certora, Hexens, Oxorio, MixBytes, and Ackee Blockchain.

Importantly, Lido DAO has never suffered a major protocol-wide hack. The protocol takes advantage of open-source code, multisig governance, and safeguards like GateSeal for emergency pauses, deposit security modules, and DAO oversight to anticipate and mitigate emerging threats. These layers of defense, combined with a multi-validator, geographically distributed network, reduce single points of failure.

What is Lido DAO token (LDO)?

Governance of the Lido DAO is powered by the LDO token, which grants voting rights to its holders. With a market capitalization of $1.14B and an all time high (ATH) price of $2.38 USD, LDO plays a central role in shaping the protocol’s future. Token holders vote on proposals, influence fee structures, and participate in selecting node operators. The governance community is highly active, with regular proposals and ongoing discussions that ensure the protocol evolves in a decentralized and transparent way.

How to buy Lido LDO?

Staking with Lido DAO is meant to be as accessible as possible. There are no minimum deposit requirements; end users can stake any amount of ETH. You can connect an Ethereum wallet, confirm the transaction, and receive stETH instantly. 

If you're looking to expand your digital currencies portfolio, LDO tokens can be a potential addition. The Tap app provides an easy and secure way for anyone with an account to add these tokens to their portfolios in no time, making it one of the most effortless trading experiences around.

You can utilize the Tap app to access the Lido ecosystem by purchasing LDO tokens with either crypto or fiat currencies. End users can then choose to store their LDO tokens securely in the integrated crypto wallet or transfer them to the Lido platform and engage in the platform's earning potential. All you need to do to get started is download the app and create an account in minutes.

Decentralized finance, or "DeFi," refers to financial services that provide many of the same features as traditional banks - like earning interest on your money and borrowing from others - but without middlemen who take a fee or charge interest, paperwork, or privacy trade-offs. A chartered accountant and Blockchain do not have much in common, but they are starting to as DeFi and FinTech take over. I

nstead of relying on financial services like banks, users can utilize smart contracts on blockchain. Cryptocurrencies ensuring even more ease of use for DeFi users, providing the hottest speeds, fees, and transparency. Defi and digital currencies are growing in popularity thanks to the perks of Blockchain technology. Let us get more into the concept and how it caters to a larger audience.

The aim and use of DeFi

Decentralized finance is the future of financial services, and it's already here. The aim of DeFi is to provide a decentralized financial services platform that is open and accessible to anyone in the world, using tech like crypto to help advance the everyday life of anyone and any business willing to give decentralization a try.

In the past decade, we've seen a rise in peer-to-peer lending platforms such as Lending Club, Patreon, BTCJam, and an explosion of digital currencies such as Bitcoin and Ethereum.

All of these developments have taken us one step closer to the decentralized future of finance that we've been dreaming about, but there's still more work to be done.

What's wrong and how can DeFi fix it

Many institutions in the financial sector are slow and expensive when it comes to providing basic services like payments. Online lender contracts can charge interest rates as high as 30 percent, and the global remittance industry charges fees that can be as high as 12 percent.

These fees and delays mean some of the most vulnerable individuals of our society are paying the highest prices for financial services when they need them most. While the traditional financial system can be slow and expensive, it doesn't have to be this way. Decentralized finance (DeFi) is an emerging category of services where trust intermediaries such as banks are replaced with cryptographic code and smart contracts, which reduces costs for everyone involved - especially when it comes to international payments.

DeFi is a new category of services that are globally accessible and built on top of blockchain infrastructure, without any charge or barrier to entry. It's also much more secure than traditional financial systems because the technology used isn't connected to a central server that can be hacked. DeFi users smart contracts applications to ensure ease of use and instant transfers of information and funds.

Your money is always yours; it's just moving from one smart contract to another. No permission from an intermediary is required in order to use it. All you need to do is have a cryptocurrency wallet, computer or mobile device, and internet connection like everyone else using DeFi services today.

DeFi isn't coming, it's already here

When you ask yourself, "where is DeFi going?", the answer is simple: everywhere. DeFi can be used from every corner of the world, and it's already available today. Innovation at its finest.

DeFi services are not theoretical. They're already being used by real people today to make real asset payments, earn interest on their digital savings, and borrow money from both friends and strangers, all without ever going through a bank or traditional financial institution. Whether you are investing, a money maker, or an asset holder, the shift to DeFi is inevitable.
Blockchain technology provides the first-ever opportunity for these separate building blocks to come together in order for the entire financial system to work seamlessly without any intermediaries, so it will only get better with time. From an economic standpoint, DeFi offers better rates and all the perks of FinTech. Cryptocurrency assets like Ethereum have seen plenty of investment opportunities arise as DeFi and Blockchain merge.

DeFi pros and cons

In order to get a complete picture of what DeFi is, it's important to understand all the good and bad parts that we are facing now. So let's dive into the details.

DeFi pros:

• The interest rate on savings and money lending is relatively high, just as it would be without intermediaries.
• Financial services are more accessible than in traditional bank systems because there aren't any barriers to entry, like non-existent internet infrastructure or bank account fees.
• Transaction and disruption times are much faster because DeFi transactions can move directly from peer to peer without having to go through intermediaries.

DeFi Cons:

• Some transactions might not be as private due to the public records of smart contracts on a blockchain (keeping that in mind, transparency is always beneficial). This however increases security because fraud or reversal can't happen.
• Access to DeFi services can be limited if you live in a part of the globe where these services aren't supported or don't have high enough adoption rates, as compared to traditional banking systems in developed countries. Regulator issues may also occur.
• There isn't a built-in mechanism for handling consumer disputes between peers because the technology simply wasn't designed with this function in mind.
• It's difficult to understand what you're getting yourself into when joining a DeFi service, since it varies from one application to the next and is based on new technology. This doesn't have to be the case in the future.
  

As of now, it's still the early days for DeFi and there are some challenges to overcome before we can look at it as a real alternative. There's still a lot of work to be done, but it will all pay off in the end.

Cryptocurrencies have truly sparked a revolution, haven't they? It feels like just yesterday they were the secret of tech enthusiasts and visionaries. Now, they’ve transformed into a bustling digital marketplace that’s open to everyone. It’s incredible to see how businesses, both big and small, are embracing these technologies, eager to be part of this vibrant growth story.

Crypto technologies are here to stay. The era where crypto was only for a specific circle of people is over and more companies are taking advantage of this steadily growing market.  More large corporations than ever before are willing to develop and invest in the advantageous market of cryptocurrencies.

The crypto-world is blooming with new developments, and it seems that developers in this field can't stop pumping out innovative updates. Skilled developers and talented specialists in this field are making exchanges more accessible with their innovative work, by turning simple tasks into ease of access for users around the globe.

Crypto banking has been the go-to for many people in need of an alternative to conventional banking. With its lack of certain features, it still provides all that is needed with crypto limitations taken care of and more!  Here's a look at some advantages of using this service over fiat currency.

The first thing you'll notice when comparing bank services side by side is how similar they can be despite being different types altogether; one might not work without another if both suit your needs well enough

Crypto banking is a revolutionary new way of doing banking. It has many advantages and disadvantages when compared with regular fiat banking. Let’s explore in more detail and analyse what are the advantage and disadvantages of crypto- banking.

The advantages:

Independent system   

Cryptocurrency, as a whole, is set to be free of reliance on outdated and archaic centralized economies allowing users to manage every aspect of it while giving them full control over its finance. There are no strings attached to trap you into a quagmire of peculiar circumstances.

Low withdrawal fees

Banks are generally charging a fee whenever you withdraw cash from an ATM or the terminal, while crypto banking enables you to withdraw cash for free up to a certain amount.

Withdrawal fees with crypto banking are one of the best features and a major step towards the future, they charge users as low as 0.01% for their transactions no matter how big the amount you try to withdraw is compared to conventional banks.

Openness

Crypto banking platforms have created opportunities for people who were previously shut out of traditional financial services. If you've credit score is low, it'll be hard to find a loan that's affordable and most banks don't offer good interest rates on their saving accounts either.

Higher returns rate

Crypto platforms offer high-yield savings accounts with rates that far exceed traditional ones, enabling their users to beat the inflationary effects. They also provide secured loans without a credit check and other financial services for people in need who are not considered eligible elsewhere.

Currency exchange

So, you’re exchanging your currency for another one? Well, that could cost as much as 4% - applied to a large amount that could be as high as 40£ for every 1000£ that you are converting! Crypto banking, on the other hand, provides an opportunity for you to exchange between various cryptos with a commission as low as 0.1% and conduct rapid peer-to-peer transfers that can be, depending on your plan, free of charge.

The cons

Online-based   

Crypto banking is based and operated online. It’s all about convenience with a quick and easy app for your smart device to control any of your operations in real-time. However, they might not be the best option for seniors or customers who are challenged with using these online services as they often need more personal attention than what this system offers them.   

Assets volatility

While cryptocurrencies have gained in popularity over the years, they remain volatile assets. Thankfully you can now use fiat currencies and stable coins with many crypto banking providers in order to eliminate this risk.

Conclusion:

In conclusion, crypto banking became an essential part of the global financial transformation happening worldwide. In view of the advancement pace it evolved at, we wouldn’t be surprised to see it prosper in the coming years, and infiltrate every aspect of our everyday life.  

As you become acquainted with the cryptocurrency industry there will be several new phrases added to your vocabulary. One of them is Hodl. While not a term used in the traditional finance industry, we'll cover the reason why hodl has become a treasured part of the cryptosphere. In this article, we explore the history of the infamous term, what it means, and why every crypto trader should be learning about the concept. 

What does hodl mean?

Hodl refers to holding a particular digital currency for a long period of time in order to make money from the price gains. In recent times, many in the crypto community have built the acronym into Hold On for Dear Life, however, this is not part of the origin story. 

Hodl has become synonymous with not selling a cryptocurrency during a bear market or period of heightened volatility. The term has become widely adopted by the crypto community and can be seen used in content across all platforms and calibres. 

Where does hodl come from?

Hodl was first conceptualised in a BitcoinTalk forum in 2013 when a user by the name of GameKyuubi misspelt the word “hold”. The inebriated user posted the following message: 

“I type d that tyitle twice because I knew it was wrong the first time. Still wrong. w/e," GameKyuubi wrote about the now-famous misspelling of "holding." "WHY AM I HODLING? I'LL TELL YOU WHY," he continued. "It's because I'm a bad trader and I KNOW I'M A BAD TRADER. Yeah you good traders can spot the highs and the lows pit pat piffy wing wong wang just like that and make a millino bucks sure no problem bro.”

In 2013, the price of Bitcoin went through a volatile period, soaring from $130 in April to $950 in December. The user encouraged fellow Bitcoin investors not to sell and rather “hodl”. 

Within an hour of the post, the new term had become a widespread meme and continues to be used a decade later. 

Hodl as a trading strategy

In cryptocurrency investing, price volatility is a constant concern. However, the concept of "hodling" offers a strategic approach to weathering these fluctuations. Hodling refers to holding onto your investments for an extended period, regardless of short-term price movements. Despite market ups and downs, hodling can provide stability and potentially lead to long-term gains. This strategy allows investors to navigate price volatility with patience and confidence in future growth.

The concept has been widely adopted by a large portion of the Bitcoin and greater cryptocurrency community as a strategy to earn gains. For Bitcoin maximalists, it’s a way of life. Many maximalists have taken on the hodl strategy to avoid any profit-eroding moves, including reactions to FUD (Fear, Uncertainty, and Doubt) and FOMO (Fear of Missing Out), more on this later.

When is the best time to hodl?

Much in the same way as the Chinese proverb, “The best time to plant a tree was 20 years ago. The second best time is now,” the best time to hodl is now. As an investment strategy, buying and holding an asset in any market is always believed to be lucrative as its value grows over time. 

Hodling is an ideological belief in the long-term prospects of blockchain technology, cryptocurrencies, and the communities that have formed around them. Some stock market traders have even adopted this mindset, although the term "hodl" remains predominantly used when referring to crypto.

Other important crypto terms to know

As you continue to build your crypto vocabulary, here are several other terms you are likely to come across. These include:

BTFD (buy the f***ing dip)

A slang term commonly used on Twitter, BTFD encourages traders to buy when the prices are low (when coins are in a dip) with the intention to make profits when the prices return to normal levels. 

FUD (fear, uncertainty, doubt)

As mentioned above, FUD refers to misinformation spread by individuals and organisations that typically encourages traders to sell. 

FOMO (fear of missing out)

Content creators or the mainstream media might use FOMO as a way to entice people to buy a coin. They play on the emotion that traders might miss out on big profits or the next big thing. 

Lambo

Short for Lamborghini, lambo refers to asset prices becoming so high that the user can sell them and buy the luxury vehicle. “When Lambo?” is a common phrase which asks when the price is going to reach such levels. 

To The Moon

Used to describe prices reaching extraordinary levels, as if they’re going so high they’re going to the moon. 

Whale

A crypto whale is an individual or organisation that holds a large amount of a particular cryptocurrency. This is generally considered to be around 10% of that cryptocurrency's total supply.

Closing thoughts

Hodling refers to a buy-and-hold strategy created from a typo in a BitcoinTalk forum in 2013. The concept remains relevant a decade later with many traders and maximalists opting to use this approach. The goal of hodling is to experience the benefits of substantial price gains and mitigate volatile markets.

The Lightning Network is a second layer solution that enables Bitcoin users to make fast and cheap transactions without compromising on security. The layer two technology allows users to enjoy the benefits of both the Bitcoin and Lightning Network layers simultaneously. Learn more about the Lightning Network solution below.

The Bitcoin trilemma

In order to compete with other payment channels like Visa, the Bitcoin network must be able to process transactions much faster and at a fraction of the cost. However, this scaling cannot come at the expense of decentralization or security.

The "Bitcoin trilemma" is a term used to outline the conflict between these three principles, scaling, security, and decentralization. 

The aim of Bitcoin Cash, Bitcoin SV, and other forks was to increase the block size in order to make Bitcoin transactions faster and more affordable on-chain.

However, these attempts failed to produce an effective method to transact quickly and inexpensively on-chain while still maintaining Satoshi's design. Hence, the Bitcoin Lightning Network.

The lightning network payment channels solution

Is it possible for the Bitcoin network to have it both ways, to keep its original architecture while also functioning as a fast micropayments network? The answer is yes, and thanks to the advent of Lightning Network transactions, Bitcoin can be used for everyday transactions like paying for a cup of coffee.

The Lightning Network is a type of layer two solution that is compatible with the Bitcoin service. This off-chain solution was first conceptualized in 2015 by Joseph Poon and Thaddeus Dryja.

The Lightning Network works by removing the burden of micropayments from the Bitcoin blockchain and instead utilizes multiple payment channels, which are controlled via multi-signature (multi-sig) Lightning Network wallets.

Why the lightning network?

How quickly can the Bitcoin network process transactions? Bitcoin is presently capable of processing between 2 and 7 transactions per second.

Visa, the current payment channel that drives your debit and credit card transactions, handles 150 million transactions each day, that's 24,000 transactions per second.

In order to make Bitcoin a competitive service to Visa, the Lightning Network needs to be implemented. This channel ensures that micropayments are instantly and cost-effectively executed, and is able to process thousands to hundreds of thousands of transactions instantly. 

The core concepts of how the Lightning Network works.

So how does the Lightning Network work? This layer 2 solution works on top of the Bitcoin blockchain, allowing thousands of micropayments to be executed at one time. This lowers the costs and increases the transaction speed of the initial transaction. There are three core components of the Lightning Network: the nodes, channels, and invoices. 

Lightning Network Nodes

This software connects with other nodes in order to form a network that connects to the Lightning Network to facilitate the sending and receiving of Bitcoin. 

Lightning Network Channel

Users of the Lightning Network establish payment channels with one another so that they may conduct transactions off-chain, which can then be settled (closed) on the mainchain (on-chain).

Invoices

Invoices are QR codes that represent requests for Lightning Network payments on the Lightning Network. Invoices include all of the data necessary to complete a payment on the network, such as the payment amount, which blockchain the invoice is associated with, expiration date, payee pubkey, routing hints, and other information.

How to use the lightning network

In order to make use of the Bitcoin Lightning Network, you will need to open a compatible Lightning Network wallet. Once you have downloaded and signed up for the wallet, you will need to send funds. Simply locate the wallet address of the Lightning Network-enabled wallet and send the funds via your normal payment channel. Once the funds appear in your wallet, you can then send transactions via the Lightning Network to other enabled wallets.
