What Is DeFi? Decentralized Finance, Explained

DeFi, short for decentralized finance, is more than just a popular buzzword in the cryptocurrency sphere. It’s a concept that is disrupting the centralized financial services model, equalizing access and bringing more control to users across the globe.

In this article, we will cover everything a consumer might want to know about DeFi, including:

•   What is DeFi?
•   How does DeFi work?
•   How DeFi is disrupting traditional financial services
•   What’s a DApp?
•   Examples of DeFi DApps

What is DeFi?

DeFi is a blanket term referring to trustless and transparent protocols that don’t require intermediaries to operate. Traditionally, financial services and products have relied on centralized authorities such as banks, financial advisors, and clearinghouses. DeFi has reengineered this power dynamic to provide the same financial services programmatically without a central authority, thus reducing fees and making financial services and products more accessible to more people everywhere.

One way to better understand this concept is to look at the two parts of the term separately.

”De” = Decentralized

DeFi’s “de” stands for “decentralized,” or distributed control. By removing power from the hands of a few central authorities and distributing it across programmatic and autonomous code, DeFi transforms a previously centralized governance model into a decentralized one controlled by no one.

”Fi” = Finance

DeFi’s “Fi” is an abbreviation for “finance”—and more specifically, it refers to financial services. DeFi has disrupted traditional finance by transforming popular and long-standing financial services into decentralized versions without any central authority. DeFi offers an alternative to traditional financial services like the following:

•   Borrowing
•   Lending
•   Investing
•   Trading
•   Saving
•   Insurance
•   Crowdfunding
•   Crowdraising

DeFi has also enabled the creation of new financial products:

•   Cryptographic tokens: There are a number of these digital assets, one of the most common tokens is a “utility token,” which serves a specific function within a digital ecosystem. One example is the Basic Attention Token (BAT), which is used as payment for advertisers, users, and content creators on the Brave browser.

•   Non-Fungible Tokens (NFTs): These tokens transform digital images (for example, works of art, a tweet, a video clip, a GIF) into unique assets that can be traded on a blockchain.

How Does DeFi Work?

With DeFi, services and products are not subject to approval by a small group of decision makers but rather by smart contracts. Like traditional contracts, smart contracts contain information and terms regarding transactions between parties, but they are completely digital. They function like a small computer program stored inside of a distributed ledger known as a blockchain, a permanent and ever-growing record of information and transactions stored in individual blocks.

DeFi shares many aspects with cryptocurrencies, including the following:

Permissionless/Borderless

DeFi applications are permissionless—completely free of charge and available to anyone who wants to use them, the only requirement being an internet-connected smartphone or computer. Unlike traditional financial services, DApps don’t require lengthy applications to create an account, as users interact directly with smart contracts from their crypto wallet.

DeFi applications are also borderless, meaning they are country-agnostic and do not discriminate against users based on citizenship, geographic location, or government standing. Anyone can access funds on a DeFi app in one country, travel to another, and access their funds abroad without any restrictions whatsoever.

Transparent

DeFi applications are built on a blockchain network, a distributed ledger composed of smart contracts that stores transaction details as they occur and builds on top of them. Transaction activities become permanently cemented into the blockchain’s history of transactions across the entire network, while constantly updating it with new ones.

Because smart contracts and blockchain technology are designed to be permanent and publicly visible, transaction records cannot be hidden or altered thereafter. This allows all transaction activities to be visible to all market participants without violating privacy, because addresses are not directly tied to personal identities. It also allows anyone to audit the code and find bugs.

Trustless

DeFi recognizes and circumvents the trust problem of traditional finance by minimizing the need for third parties, banks, and clearinghouses. For most DeFi apps, users interact with self-executing smart contracts based on conditions being met, as opposed to waiting on approval from overseeing stakeholders.

Interoperable

Different DeFi applications (DApps) are designed to be compatible with each other, allowing DApps to be built or composed by combining DeFi products. This interoperability enables simple blockchain operation and a scalable ecosystem.

How DeFi is Disrupting Traditional Financial Services

Financial services such as borrowing, lending, and investing have traditionally been areas with a high barrier to entry, typically preventing people with little money or financial expertise from gaining access to these services. Though traditional banking is common in first world countries, there are over 1.7 billion people who are unbanked globally , representing over 30% of the human population, according to the most recent World Bank Global Findex report.

Domestically, 22% of US adults are underbanked or unbanked , according to the Federal Reserve’s most recent Report on the Economic Well-Being of U.S. Households. “Underbanked” means they have at least one account at an insured institution but also obtain financial services outside of the banking system such as money orders, check-cashing stores, payday loans, pawn shops, and more. The FDIC found in its 2019 “How America Banks” survey that 5.4% of US adults are unbanked entirely , having no accounts with any financial institution.

With the advent of DeFi, previously inaccessible financial services such as borrowing, saving, investing, and international payments are now accessible to anyone with access to the internet regardless of age, income, nationality, financial background, or credit score. To date, there are currently 3,809 DApps, with 140.59k daily active users.

What’s a DApp?

A DApp, or decentralized application, is a digital program that runs on a decentralized blockchain network without the control of a single authority. DApps are open-source and the basis for any cryptocurrency project; Bitcoin is considered the first DApp.

While the actual DApps themselves are typically ‘unownable’ services, DApps sometimes distribute underlying tokens that allow users to buy crypto.

DeFi applications can be built on any decentralized protocol but are primarily built on Ethereum, the premier decentralized blockchain network used for building new DApps which is powered by smart contracts and its native digital currency Ether. Ethereum enables developers to write smart contracts on the Ethereum blockchain which automatically execute when certain conditions are met. Smart contracts are then stored and executed across every node on the Ethereum network, making them decentralized applications.

The Ethereum DApps enable developers to build far more advanced technology than just trading cryptocurrency. Instead of needing to develop a new blockchain for every application, Ethereum created a secure platform for DApps to be built and deployed. Ethereum is one of the most popular blockchain networks and its native Ether token is the second-largest cryptocurrency behind Bitcoin.

DApps are similar to centralized applications but benefit from the features of existing on a decentralized blockchain network. Because they don’t have a single point of failure, they are thought to be more secure against cyberattacks. A distributed network of nodes maintains the network and prevents any system downtime common among centralized applications. DApps aren’t owned by anyone and aren’t subject to owner malfeasance such as embezzlement.

Examples of DeFi DApps

DeFi is a new space that only started to see the launch of live products in 2017 or so. Here are a few of the most popular types of DApps that emerged in 2020:

Borrowing and Lending Platforms

Securing a traditional loan typically involves submitting an application at a financial institution with ample personal information, agreeing to a credit check, pledging collateral (if necessary), and waiting for interest to be factored in by the intermediary for facilitating the loan that’s sourced by a federal institution. With DeFi, smart contracts connect interested lenders and borrowers, impose terms of loans, and impose interest without a third party. Lending DApps typically require collateral to be pledged in the form of crypto or stablecoins as a measure of insuring risk taken on by the lender. Through smart contract automation and elimination of a third-party intermediary, DApp lending platforms have formed loans with interest sometimes below 10 percent .

Decentralized Exchange (DEX)

A decentralized exchange (DEX) is an exchange that uses smart contracts to enforce trading rules, execute trades, and securely handle funds if necessary. Unlike centralized exchanges, DEXs don’t have an exchange operator nor do they require account creation, identity verification, or impose exchange fees. Because DEX’s are unique and don’t have a centralized authority, it is debated whether or not some or all DEX’s are subject to the crypto regulations enforced on centralized exchanges. Further, many DEX’s do not custody users’ funds at any point during trading, adding additional uncertainty as to the application of regulations. However, like any exchange, they do require liquidity to be able to match buyers and sellers.

Betting Platform

DeFi disrupts one of the most restricted and heavily centralized industries in existence: Gambling. In addition to an intensive and exclusive registration process, users of traditional online gambling platforms are subject to getting their betting limits lowered and accounts closed. With a decentralized peer-to-peer platform, this is not possible.

Several betting DApps have been launched as global betting platforms with no limits, allowing users to bet on traditional sports events as well as real-world events such as economics, elections, pop culture, and m
ore. Users can place bets using digital currencies and get rewarded in them upon winning a bet. Users buy or sell on a particular outcome of an event, with the DApp showing the current odds based on active user bets.

NFT Marketplace

An innovative DeFi development has been the launch of marketplaces for exchanging non-fungible tokens , or NFTs. NFTs are unique cryptographic tokens that represent digital goods such as online gaming goods and also tokenize real-world assets such as art, collectibles, company equity, and commodities. An NFT marketplace allows users to freely buy, sell, and trade NFTs representing otherwise non-fungible assets.

The Takeaway

DeFi is a term for the decentralized finance model that’s reengineering traditional financial services and products. By reallocating decision-making from central authorities to executable code within smart contracts, many financial services are becoming cheaper and easier to access for anyone.

The Difference Between Public and Private Cryptocurrency Keys & Why It Matters

For those just starting to invest in cryptocurrency, it’s essential to understand what cryptocurrency keys are and how public and private keys work. Every cryptocurrency wallet has a public and a private key. Not only are keys used during the process of sending and receiving cryptocurrencies, but they are also integral to keeping cryptocurrency holdings secure.

This article covers the differences between private and public keys, how they enable crypto trading and storage, and what investors need to do to keep their crypto secure.

What Is a Private Key?

A private key is a cryptographic string of numbers and letters which is mathematically related to a public key, but impossible to reverse engineer. This is due to its strongly encrypted code base.

A private key is what gives a wallet owner access to their funds and allows them to send funds to others. Think of a private key as a password, used to decrypt messages and transactions.

A public key, on the other hand, can be shared publicly to allow others to send cryptocurrencies to a wallet. Think of a public key as encrypting messages and transactions. In fact, a wallet address is basically a hashed version of a public key—shortened and compressed in order to send an address.

Each cryptocurrency uses its own algorithms for creating keys, so some are longer than others.

Why It’s Important to Secure Your Private Key

It’s very important to keep private keys secure and to keep a back-up in a safe, offline location. If anyone accesses your private key they can steal funds from your wallet, and if a private key gets lost there is no way to retrieve the funds in the wallet.

This can’t be stressed enough. If a private key gets lost or stolen, the funds secured by it are lost too.

It’s estimated that about 20% of all Bitcoin—$3.7 million—that has been mined is lost forever, and 1500 more Bitcoins get lost every day.

How Do Public and Private Cryptocurrency Keys Work?

Certain crypto exchanges and wallets store users’ private keys in an encrypted form. This can be more convenient for sending and withdrawing funds, but can make users vulnerable to security breaches. If using this type of wallet or exchange it’s imperative to make sure the company is reputable, and one might want to consider only keeping a fraction of their cryptocurrency holdings in this type of wallet at any given time.

Although the same private key is used for every transaction from a particular wallet, it never gets shared with the public network, making it possible to securely use it over and over again. Each transaction gets linked to a unique digital signature which confirms the validity of the wallet owner and ensures that the transaction can’t be changed later.

Bitcoin Private Keys

When someone creates a new bitcoin wallet, a 256-bit long private key beginning with the number 5 is chosen randomly. A public key connected to that private key will also be generated, which is the address used to receive Bitcoins. The public key begins with the number 1. It is next to impossible to reverse engineer to figure out the private key associated with a public key.

Here is an example of what Bitcoin keys look like:

Storing Crypto with Private Keys

Cryptocurrencies themselves are not stored locally on one’s phone or laptop. They are stored on the blockchain and accessed using public and private keys. Wallets keep track of how many coins are held by any particular user. This is similar to a traditional online bank account. When an account owner logs into their account online, it tells them how much money is in their account, but the money itself isn’t stored online. The difference is that cryptocurrencies are digital currency, whereas online funds relate to fiat currency backed by physical assets, at least in theory.

If a wallet owner loses track of their phone, laptop, or hardware wallet, they can still gain access to their cryptocurrencies if they have the private keys, or in some cases by using a backup code or recovery phrase provided when the wallet gets created. This is why it’s so important to make a backup of one’s private keys or backup codes.

Different Crypto Wallets Use Different Private Keys

There are a few different types of crypto wallets, each of which utilize private keys in a different way.

Hot Wallets

Some online wallets and exchanges store private keys on behalf of the user. These may be mobile apps or web apps, and are also known as hot wallets. Crypto holders can also send and receive funds on decentralized exchanges, which are peer-to-peer networks that don’t have a central authority.

Desktop Wallets

Desktop wallets get downloaded from the internet but then exist offline on one’s computer. The private key may be written down or stored in an offline file.

Hardware Wallets

Hardware wallets, such as the Trezor and Ledger devices, store private keys offline, and funds can’t be accessed without the device and a pin code. They generally have small screens and buttons used to verify transactions when the device is plugged into a computer. This makes them very secure. If the device breaks or gets lost, the funds can be retrieved using a backup code. These devices support many different cryptocurrencies, including Bitcoin, Litecoin, Ethereum, and more. Both hardware wallets and paper wallets are known as cold wallets.

Paper Wallets

A paper wallet is simply a piece of paper where one writes down their private keys or that gets printed out with the keys on it. This is perhaps the most secure way to store private keys, but it’s important to keep the paper dry and in a safe and memorable place. Paper wallets for Bitcoin can be generated at bitaddress.org , while the user is offline.

Trading Crypto With Private Keys

When a wallet owner wants to access or send funds, they will be asked for their private key, or to verify the transaction if the key is held by a wallet service. Crypto wallets generally come with QR codes that can be scanned for sending funds, making the process faster and easier. If even one letter or number in an address is entered incorrectly the transaction will go to the wrong wallet, so using a QR code can help prevent that from happening.

Bitcoin and many other crypto transactions are irreversible. For this reason, it’s very important to double- or even triple-check the address that funds are being sent to and ensure that it’s correct. One should never send funds to an unverified company or unknown individual, as there have been countless instances of crypto fraud.

Tracking Transactions Using Keys

While a private key will get you into your own account, there are other, more anonymous ways to track other crypto transactions. There is a publicly viewable ledger for almost every cryptocurrency showing transactions between wallet addresses. One can also view all incoming and outgoing transactions from any particular wallet address, without knowing who the address belongs to.

This can be useful during the transaction process, because sometimes it takes several minutes or even longer for a transaction to go through and funds to transfer into a wallet. However, one can often see that the funds were sent from the outgoing address, confirming that the transaction has been initiated.

The Takeaway

Understanding private and public keys is integral to investing in and using cryptocurrencies. While a public key is in fact public-facing, one’s private key should always be kept secure, because with it you—or anyone else—can execute crypto transactions, and without it you have no access to your cryptocurrency.

Homeowners Insurance Coverage Options to Know

Homeowners Insurance Coverage Options to Know

If you’re like many Americans, your home is the single largest purchase you’ll ever make–and one you likely can’t afford to replace if disaster strikes.

That’s why homeowners insurance can be a wise investment. This type of insurance will compensate you if an event covered under your policy damages or destroys your home or personal items.

It will also cover you in certain instances if you injure someone else or cause property damage.

Although having homeowners insurance isn’t required by law, mortgage lenders often require you to insure your home until you’ve paid the loan in full.

Choosing the right coverage for your home–and understanding exactly what is (and what isn’t) covered–can be confusing though.

Some policies cover more than others, and how much coverage you need will depend on your circumstances, as well as your risk tolerance.

Here’s what you need to know about the options available for protecting your home.

Recommended: What’s the Difference Between Homeowners Insurance and Title Insurance?

What Does Homeowners Insurance Typically Cover?


Most standard homeowners insurance policies include six different kinds of important coverage.

•  Dwelling: This covers the physical structure of the home itself, including its foundation, walls, and roof, as well as structures attached to the home such as a front porch.
•  Other structures on your property: This covers things that aren’t attached to the main home structure, like garages and fences.
•  Personal property: This includes personal items including clothing, furniture, and everything else that you put inside your home.
•  Additional living expenses: This provides funds to pay for temporary living expenses, such as hotel costs and restaurant meals, while your home is being repaired or rebuilt.
•  Liability coverage: This protects you against lawsuits and damages you or your family cause to other people or their property.
•  Medical coverage: This is offered to foot the bills incurred by somebody who is injured on your property, whether it’s your fault or theirs.

What Type of Events Does Homeowners Insurance Cover?


The most common type of homeowners insurance policy on the market is called HO-3 insurance.

This insurance includes coverage of 16 specifically named perils, but it may also offer “open peril” coverage, which means that anything that damages your dwelling that is not specifically excluded in the paperwork will be covered by the policy. (This coverage generally does not extend to your personal property, however.)

The 16 named perils typically include:

•  Fire or lightning
•  Windstorms or hail
•  Explosions
•  Riots
•  Damage caused by aircraft
•  Damage caused by vehicles
•  Smoke
•  Vandalism
•  Theft
•  Volcanic eruptions
•  Falling objects
•  Damage due to the weight of ice, snow or sleet
•  Water or steam overflow from plumbing, HVAC systems, internal sprinklers and other appliances
•  Damage due the “sudden and accidental tearing apart,cracking, burning, or bulging” of an HVAC, water-heating, or fire-protective system
•  Freezing of pipes and other household appliances
•  Damage due to a power surge

What Isn’t Covered by Homeowners Insurance?


Homeowners insurance typically covers most scenarios where a loss could occur. However, some events are generally excluded from policies. These often include:

•  Earthquakes, landslides and sinkholes
•  Infestations by birds, vermin, fungus or mold
•  Wear and tear or neglect
•  Nuclear hazard
•  Government action (including war)
•  Power failure

What if you live in a flood or hurricane area? Or an area with a history of earthquakes? You may want to consider a rider (which is supplementary coverage to an existing policy) for these or an extra policy for earthquake insurance or flood insurance.

Home insurance policies also typically set special limits on the amount of reimbursement you can receive in categories such as artwork, jewelry, appliances, tools, electronics, clothing, cash, and firearms.

If you own something particularly valuable, such as fine art painting or piece of expensive jewelry, you might want to purchase a rider that you will be reimbursed in full for it.

What Should I look for in a Homeowners Insurance Policy?


Homeowners insurance companies typically offer three different reimbursement models or levels of coverage.

Which one you choose can be an important decision. That’s because it will impact how you will be reimbursed in the event your home is damaged or burglarized, and also the cost of your premiums.

These are the most common homeowners policy options, listed from least to most costly.

Actual Cash Value


Actual cash value typically covers the cost of the house plus the value of your belongings after deducting depreciation (i.e., how much the items are currently worth, not how much you paid for them). If your five-year-old TV was stolen, for instance, you would not likely get reimbursed for the cost of a brand-new one.

Replacement Cost Value


Replacement value policies generally cover the actual cash value of your home and possessions without the deduction for depreciation, so you would likely be able to repair or rebuild your home and re-buy your possessions up to the original value.

Extended Replacement Cost Value


This coverage will typically pay out more than the original value of your home and belongings, up to a specified limit, if it actually costs more to fix your home and/or replace your possessions.

The limit can be a dollar amount or a percentage, such as 25% above your dwelling coverage amount. This gives you a cushion if rebuilding is more expensive than you expected.

Guaranteed Replacement Cost Value


Guaranteed Replacement Cost is the most comprehensive coverage. This inflation-buffer policy pays for whatever it costs to repair or rebuild your home and replace your possessions—even if it’s more than your policy limit.

This type of coverage can be ideal since you typically don’t need just enough insurance to cover the value of your home, you will likely need enough insurance to rebuild your home, preferably at current prices.

Understanding Homeowners Insurance Deductibles


Homeowners policies typically include an insurance deductible — the amount you’re required to cover before your insurer starts paying.

The deductible can be a flat dollar amount, such as $500 or $1,000. Or, it might be a percentage, such as 1 or 2 percent of the home’s insured value.

When you receive a claim check, an insurer typically subtracts your deductible amount from the total claim.

For instance, if you have a $1,000 deductible and your insurer approves a claim for $8,000 in repairs, the insurer would likely pay $7,000 and you would be responsible for the remaining $1,000.

Choosing a higher deductible will usually reduce your premium. However, you would likely have to shoulder more of the financial burden should you need to file a claim.

A lower deductible, on the other hand, means you might have a higher premium but your insurer would likely pick up a greater portion of the tab after an incident.

The Takeaway


Of the many types of insurance coverage out there on the market, homeowners insurance is one of the most important–it literally protects the roof over your head, which very well might also be your most valuable asset.

Homeowners insurance covers damage to your home and its contents. It also typically reimburses you for losses due to theft and pays out if visitors to your property are injured.

Your policy may also pay for living expenses, such as a hotel stay, if your home becomes uninhabitable.

In some cases, you can get additional policies or riders for events not covered by your regular home insurance, such as flooding, as well as extra coverage for any highly valuable possessions.

Because choosing the right homeowners insurance company and right amount of coverage can be overwhelming, SoFi has partnered with Lemonade to help bring customizable and affordable homeowners insurance to our members.

Prices start as low as $25 per month, and Lemonade gives back leftover money to charities of your choice.

How Safe is Blockchain? Blockchain Security Guide

How safe is blockchain technology? It has proven to be a powerful technology for protecting the integrity of vital information. But that doesn’t mean it’s entirely safe.

The technology has become increasingly prevalent in recent years as the cryptocurrency markets have moved toward center stage. One reason for its rapid adoption is that blockchain is designed to offer unparalleled security to digital information.

In its short life, blockchain—also known as distributed ledger technology—and the cryptocurrencies it powers has seen its share of successes and failures. And as its applications spread, blockchain security has become more important—and not just for cryptocurrency investors.

How Blockchain Works

In some ways, blockchain technology is like the internet, which relies on a decentralized network rather than just a single server.

Blockchain uses a decentralized, or distributed, ledger that exists on a host of independent computers, often called nodes, to track, announce, and coordinate synchronized transactions. This differs from traditional trading models that rely on a clearinghouse or exchange which tracks everything in a central ledger.

Each node in the decentralized blockchain constantly organizes new data into blocks, and chains them together in an “append only” mode. This append-only structure is an important part of blockchain security. No one on any node can alter or delete the data on earlier blocks—they can only add to the chain. That the chain can only be added to is one of the core security features of blockchain.

By referring to the chain, participants can confirm transactions. It cuts out the need for a central clearing authority.

Blockchain Security Basics

Blockchain is not immune to hacking, but being decentralized gives blockchain a better line of defense. To alter a chain, a hacker or criminal would need control of more than half of all the computers in the same distributed ledger (it’s unlikely, but possible—more on that later).

The largest and best-known blockchain networks, such as Bitcoin and Ethereum, are public, and allow anyone with a computer and an internet connection to participate. Instead of creating a security crisis, having more people on a blockchain network tends to increase security. More participating nodes means that more people are checking one another’s work and calling out bad actors.

That’s one reason why, paradoxically, private blockchain networks that require an invitation to participate can actually be more vulnerable to attack and manipulation.

Permissioned vs. Permissionless Blockchains

As the names imply, permissioned or private blockchains are closed systems that require an invitation to join. This can be useful for businesses like companies and banks, which may want more control over data and thus would restrict outsiders from joining. Ripple, which was created by the banking industry as a way to make low-cost transactions, is an example of permissioned blockchains.

Permissionless blockchains are public—anyone can transact on these blockchains, with no one in control. The data is copied and stored on nodes worldwide, and individuals can remain more or less anonymous. Bitcoin, Ethereum, and Litecoin are all examples of permissionless blockchains.

The Role of Miners in Blockchain Security

As Bitcoin and other forms of crypto have grown in popularity, so has the process of mining. For speculators, cryptocurrency mining is a way to receive crypto coins or tokens. For the cryptocurrencies themselves, mining contributes to blockchain security, as it’s a way to ensure the integrity of the underlying blockchain of their currencies.

Miners verify the transactions to make sure that they are valid and in line with the blockchain code. For popular crypto currencies like Bitcoin and Litecoin, they submit their proof of work (POW) algorithmic evidence supporting or denying each transaction, and receive payment in the form of coins.

How Blockchain Security Prevents Double Spending

For payments and money transfers, blockchain is useful in preventing “double-spending” attacks. These attacks are a core concern for cryptocurrencies. In a double-spending attack, a user will spend their cryptocurrency more than once. It’s an issue that doesn’t arise with cash. If you spend $5 on a sandwich, then you no longer have the $5 to spend. But with crypto, there’s a risk that a user will spend the crypto multiple times before the network finds out.

Blockchain helps prevent this. Within the blockchain of a given cryptocurrency, the entire network needs to reach consensus on the transaction order, to confirm the latest transaction, and to post them publicly.

Bitcoin was the first form of crypto to solve the problem of double spending. And it serves as an example of how blockchain helps preserve the integrity not just of currency, but of records as a whole. If someone wanted to spend the exact same bitcoin in two places by sending it to two recipients simultaneously, then the two transactions would first go into a pool of unconfirmed transactions.

The first transaction to be confirmed would be added to the coin’s blockchain as the next data block in its transaction history. The second transaction—being connected with the block in the chain that had already been added to—wouldn’t fit into the chain, and the transaction would fail.

Blockchain Security Risks

But even with the security provided by the very nature of blockchain itself in addition to a global network of nodes and miners constantly confirming and protecting the integrity of a blockchain, there are still risks.

No Human Safeguards

One risk is also a supposed benefit: blockchain creates a seamless way to execute transactions. There’s no manual intervention required to send or receive money, which eliminates some of the more human safeguards that have evolved over time. While the technology has benefits for ensuring the integrity of the assets identity, or information involved, it is completely agnostic about the sender and receiver. This is one area where a central clearinghouse can exercise valuable discretion.

While this doesn’t pose a direct risk to any crypto assets an investor may hold at the moment, it could lead to issues later. Many critics of bitcoin and other forms of crypto point to its growing use by criminal and terrorist groups to circumvent money-laundering and other bank regulators. The anonymity that crypto allows also made it popular on the Silk Road online bazaar of illegal goods and services that flourished between 2011 and 2013.

That criticism has led to increased interest from regulators in the US and abroad, which could ultimately lead to new laws about how blockchain can and can’t be used.

High Costs

Other critics point to the high cost of maintaining the networks that make blockchain function. The process of mining these coins, which is vital to their integrity and survival as a working currency, consumes vast amounts of energy. The total energy consumption of the bitcoin network is equal to the electricity needs of 2 million U.S. homes, according to Morgan Stanley.

Because miners are paid in coins, that creates a real risk. If the price of the coins go down low enough, or the price of electricity rises high enough, then people may decide the game isn’t worth the candle.

Hacker Activity

While the very nature of how blockchain works—using decentralization, consensus, and cryptography—ensures that transactions are basically tamper-proof, hackers have still found ways to defraud the system over the years. In 2019 alone, twelve crypto exchanges were hacked.

These are a few ways the system is vulnerable to hackers.

•  Phishing is one problem, in which scammers send bogus emails in an attempt to get wallet key credentials from crypto users. (Securely storing your cryptocurrencies isn’t enough—it’s also essential to stay vigilant about protecting sensitive information.)
•  There’s also a chance that one miner or a large enough group of miners could eventually gain control of more than 50% of a network’s mining power. In that case, they’d gain control over the ledger.
•  In other situations, hackers can access real-time data as it’s being routed between internet service providers.

How to Choose a Secure Blockchain Network

There are a few things a user can do to make sure the crypto exchange they select is secure. Here’s a checklist to use when choosing an exchange:

•  Does the exchange engage auditors to look for flaws in the system?
•  Does the exchange store assets in “cold storage” (someplace without an internet connection—think of a paper wallet with a private key)
•  Do they offer security options like alerts for suspicious transactions? Two-factor authentication? Multi-signature transactions?

The Takeaway

For Blockchain, security is both a strength and a concern. Cryptocurrency transactions—including paying with crypto, investing in crypto, and crypto lending—is anonymous and protected in part by the very way blockchain technology is built. But as with most other technologies, it’s not completely immune to tampering.

That said, users can protect themselves by securely storing their private keys and not falling prey to phishing emails looking for personal information in order to hack your account.

5 Easy Steps to Invest in Litecoin

5 Easy Steps to Invest in Litecoin

When anyone mentions crypto, the first name that usually comes to mind is Bitcoin. However, there are hundreds more cryptocurrencies that have been around nearly as long as the first cryptocurrency but at a fraction of the price, such as Litecoin.

If Bitcoin is digital gold, then Litecoin is digital silver; it is faster and more abundant. (N.B.: Both are risky investments.) Casual investors can invest in this virtual coin in just a few steps.

Understanding the Litecoin Basics

Litecoin (LTC) is a peer-to-peer cryptocurrency and open-source software project like Bitcoin, designed for cheap and fast transactions. It was created in 2011 through a soft fork of the Bitcoin blockchain and was one of the first Bitcoin spinoffs or “altcoins.”

One of Litecoin’s lead premises was to provide faster transactions by confirming a new block on the Litecoin Network every 2.5 minutes as opposed to Bitcoin’s 10 minutes. Like Bitcoin, Litecoin can be purchased and sold through online platforms such as digital currency exchanges and alternatively, be mined with specialized computer hardware through a version similar to Bitcoin’s Proof of Work mechanism.

Litecoin’s price is generally correlated to Bitcoin’s price movements, rising when Bitcoin rallies and falling when Bitcoin declines. Due to Litecoin’s faster transaction speeds and lower fees, some merchants, vendors, and blockchain applications have introduced Litecoin payment processors.

This demand has also contributed to many major global cryptocurrency exchanges to list Litecoin, making buying cryptocurrency more accessible around the world.

Buy Litecoin in 5 Steps

1. Get a Litecoin Wallet

The first step to buying Litecoin is having somewhere to store it. There are several ways to store Litecoin depending on convenience or security needs. Though cryptocurrency exchanges and investing platforms offer custody services to hold cryptocurrency, investors typically only use exchanges and investing platforms to purchase Litecoin and then withdraw the coins to a Litecoin wallet.

The first step is to determine which type of cryptocurrency wallet better fits investing needs, of which there are two distinctly different types.

Hot Wallet

A “hot wallet” is an easy and free way to store Litecoin through a service connected to the internet. Hot wallets are popular and typically accessed through websites, browser extensions, or desktop applications.

Hot wallets are also convenient for users because they are always online and can be accessed from a different device if an old device becomes inoperable. However, it’s because hot wallets are connected to the internet that they can be more vulnerable to hacks and theft. When creating a wallet, the user is provided with three important components to be safely stored for future use:

•  Public Key Address: The wallet’s public address that is shared with others in order to receive Litecoin. This will need to be readily accessible to withdraw funds to the wallet.
•  Private Key: Private password consisting of an arbitrary string of letters and numbers required to access the wallet’s funds.
•  Seed Recovery Phrase: A backup login method in case the private key gets lost, which consists of a list of random words in a sequential order. Some wallet providers may offer different length seed phrases but typically contain 12, 18, or 24 random words.

Coinbase, the largest U.S. cryptocurrency exchange, also provides hot wallet services. Mycelium, Exodus and Electrum are other examples of some hot wallet providers.

Cold Wallet

Another option for investors concerned about online safety is a “cold wallet,” a physical device that must be purchased and is only ever connected to a computer to send or receive cryptocurrency as needed. Otherwise, it is safely stored by the individual owner where it remains offline and disconnected from any computer or internet connection.

This security measure creates an “air gap” between potential malicious parties and any form of online or local area network (LAN) access to Litecoin in storage. While individual cryptocurrency owners tend to self-custody and store cold wallets at home, it is not unheard of for investors to take further measures and store a cold wallet in a bank-protected vault. Trezor and Ledger are examples of cold wallet makers.

2. Create Account on Cryptocurrency Exchange

The safest method for buying cryptocurrency is through a reputable digital currency exchange, an investing platform exclusively for buying and selling digital currencies.

Coinbase is the largest cryptocurrency exchange in the U.S. by crypto volume. Binance, Gemini, Kraken, Cash App and Bisq are other well-known, popular markets.

The first step to invest in Litecoin is to create an account on a digital currency exchange or investing platform that sells Litecoin. This starts by registering a username, complex password, and storing them in a safe place offline.

Next, new users will be required to verify their identity by providing basic personal information such as date of birth, address, nationality, and providing a form of personal identification such as a valid government-issued driver’s license or passport.

Financial companies are required to comply with SEC-mandated Know Your Customer and Anti-Money Laundering (KYC/AML) cryptocurrency regulations to prevent fraud and provide an assurance of customer due diligence. This process is subject to approval and may take a couple days before being approved to continue funding the account and using it to trade.

3. Deposit Funds Into Cryptocurrency Account

Once the account is created, a funding method must be linked to the account to transfer money into the account. Bank accounts are typically used to fund accounts but some platforms may also allow other third party payment providers or wire transfers.

The user may be asked to provide the bank account number and routing number in order to link a bank account, after which a series of microtransactions may be initiated to confirm a successful connection.

After an account is successfully connected, funds may be transferred from the funding account to the investing account, which can then be used to buy Litecoin. Funds may be deposited up to a certain dollar amount and will then be available to trade. Prices of Litecoin have soared since the end of 2019, rising more than 300% to $174.48 near the beginning of February 2021.

4. Submit Buy Order

Once the account is funded, it’s time to buy Litecoin. It may be possible to pick from two options: a market order or limit order.

After a buy order executes, the required funds will be debited from the account’s balance and the purchased coins will appear in the account. The newly-purchased Litecoin is immediately available for spending, trading, or transfer.

Market Order

Market orders are more common for even simple investing platforms. A market order simply buys the designated amount of Litecoin at the current market price. This can result in some price slippage especially during volatility, but guarantees that a buy order is executed immediately.

Limit Order

Limit orders allow for some flexibility and precision in buying only at certain prices. An investor can determine at what price they want to buy and nothing higher. If the price is never met, the trade doesn’t execute. A limit order can be set for the day or in some cases for a couple months.

5. Withdraw Litecoin

After purchasing Litecoin, the next step is to withdraw it from the investing platform and send it to a private and secure wallet. This process is completed as follows:

•  Initiate a withdrawal request
•  Input the desired token withdrawal amount
•  Copy and paste the newly created wallet’s public address
•  Submit the withdrawal request

The request should initiate immediately and place the withdrawal order into a queue on the Litecoin network. Because Litecoin’s transaction speed is multiple times as fast as Bitcoin’s, it should only be a matter of minutes before the requested withdrawal amount appears in the designated wallet’s balance.

Is Litecoin a Good Investment?

Litecoin is one of the oldest cryptocurrencies having been around since 2011. It has maintained its position as one of the most popular cryptos, consistently being a top-five cryptocurrency based on token price and market cap.

While there are many different types of cryptocurrency, some of which are not yet actively functioning or as time-tested, Litecoin’s network has been among the fastest transaction speeds in cryptocurrency for years. Litecoin is easily accessible on many global digital currency exchanges and investing platforms, providing the token with high liquidity and global market penetration.

After initially trading for a few cents in late 2011, Litecoin has seen exponential growth over time. Litecoin also has a total maximum supply of 84 million compared with Bitcoin’s maximum supply of 21 million, making Litecoin four times as abundant as Bitcoin but more scarce than many other large cryptocurrencies such as Ripple and Ethereum.

The Takeaway

Proponents of cryptocurrencies say the market is here to stay and disrupt the traditional financial sector. Retail investors have immediate access to investing in disruptive cryptocurrency projects like Litecoin alongside accredited investors.

As the cryptocurrency asset class transitions from one market cycle to another, some investors argue that it can continue to provide outsized investment opportunities.

In addition to Bitcoin, investors have other investment options in cryptocurrency including Litecoin. With the option of buying whole or fractional coins, Litecoin is a user-friendly investment option that allows users to buy as much or as little Litecoin as desired and transfer it quickly.
