What is Distributed Ledger Technology (DLT)?

mm

Updated

 on

Distributed Ledger Technology (DLT) is one of the fastest-growing tech sectors in the world. While most people consider the terms blockchain and DLT as interchangeable, this is not the case. In fact, blockchains are just one small portion of the DLT sector. Importantly, a distributed ledger is a database that exists in duplicate across multiple points of a network.

As the name suggests, the main characteristic of these networks is their decentralization. Consequently, all DLTs contain the technological infrastructure and associated protocols required to run a distributed network. These processes include the ability to collect, validate, and access immutable data across several nodes of the same network.

How Distributed Ledger Technology Works

DLTs can function in many different ways. However, all DLTs rely on some form of consensus to confirm the state of the network. A consensus mechanism is a protocol that allows network participants to validate the network’s state. In terms of blockchain distributed ledger technology, the most common forms of consensus mechanisms are the Proof-of-Work (PoW) and the Proof-of-Stake (POS) systems.

Both of thee mechanisms accomplish the same task, albeit through different means. In a PoW system, network nodes compete to solve a complex mathematical equation. The first node to complete the equation gets to add the next block to the blockchain. This process is very secure but it does require intensive electrical usage. These high energy demands led developers to seek viable alternatives.

In a PoS system computers still compete to add the next block, but in a different manner. Users validate blocks utilizing a staking mechanism. Staking is the act of placing your coins in a synchronized network wallet. The nodes with the most coins and the longest staking times are more likely to get to add the next block of transactions and receive the reward.

Benefits of Distributed Ledger Technology

The benefits of DLT are too immense to ignore. DLT networks provide a transparent and secure method for businesses and individuals to conduct true peer-to-peer commerce. These systems provide effective management of dynamic data at levels that were unimaginable just a few years prior.

Trustless Nature

DLTs are a huge upgrade over centralized systems for many reasons. For one, these networks supply an immutability and transparency record of all transactions. In a public DLT, anyone can go into the network and verify what transactions transpired. This openness affords users more confidence.

Secure Alternative

Decentralization underpins the whole concept of a DLT. These networks are more secure because they remove any centralized attack vector. In a DLT network, the risk shift from one centralized target over to thousands of smaller vectors. Since these smaller nodes don’t possess vast amounts of valuable assets such as a central governing authority, they are less likely to experience a major attack.

Additionally, DLTs utilize high tech security to ensure their network remains pure. Nodes that enter malicious or false data get expelled from the network immediately. This strategy helps to streamline the entire consensus process.

Cost Reduction

The trustless nature of DLTs makes them an attractive alternative for firms seeking a secure network solution. DLTs such as Blockchain networks eliminate the need for third-party verification systems. Since each of these systems add more costs and time to each transaction, eliminating them increases efficiency significantly. Companies understand the peer-to-peer nature of these networks makes them more affordable to run than a centralized system.

Differences between Blockchain and DLTs

As of recently, the terms blockchain and DLT seem to have been muddied. Understanding the differences between these terms is an important step in becoming a more informed investor. Think of blockchain as only a tiny section of the distributed ledger sector. Importantly, not all DLTs are blockchains. In fact, DLTs have been around for centuries, long before the first computer ever existed.

Additionally, not all blockchains are decentralized but they are DLTs. Centralized blockchains utilize a network of nodes but they rely on a central authority for the final transaction verification. These systems are more popular within traditional financial systems because they enable the centralized party the ability to alter and correct transactions when necessary. It’s worth your time to study up on the exact differences. In this way, entrepreneurs and business leaders can determine which solution best fits their strategy.

History of DLTs

DLTs have a long and remarkable history. While the most common form of DLT spoken about today is blockchain, these systems have been in use for centuries. It’s vital to understand that blockchain tech improved upon DLTs because it was the first system to solve the double-spending problem.

Basically, electronic currencies that rely on DLTs were already around before Bitcoin. However, no one had configured how to remove the ability for nefarious actors to double-spend digital currency. It wasn’t until Satoshi Nakamoto introduced Bitcoin’s whitepaper that these issues finally came to an end and digital currencies took flight.

Some of the earliest forms of DLTs began in ancient times. Historians reported that in ancient Rome, there was a distributed ledger that allowed its citizens to make purchases in any region of the empire. This ledger helped to spur economic activity across the empire and helped Rome achieve its historic status.

Digital DLTs

Digital versions of DLTs began to pop up as early as 1991. At this time, the first concept of a DLT as its known today appeared. The first DLT was merely a concept written about in a paper by the two researchers named Stuart Haber and W. Scott Stornetta. In their paper named  “How to Time-Stamp a Digital Document the two discussed procedures for certifying the creation and modification of digital documents” the basics of a digital DLT began to take shape.

2002

In 2002 David Mazières and Dennis Shasha built on this concept with their work. These two innovative developers introduced the concept of “Building secure file systems out of Byzantine storage multi-user network file system called SUNDR (Secure Untrusted Data Repository)”. This document was the first to discuss the possibility of using blocks to organize transactions.

2005

In 2005 Nick Szabo famously proposed one of the earliest forms of digital cash – Bit gold. His proposal was revolutionary at the time. It introduced never before seen concepts such as client puzzle functions and the Proof-of-Work function. Many of these concepts made their way into Bitcoin’s core coding.

Interestingly, many people believed Nick Szabo to be the real Satoshi Nakamoto because of these similarities. Sadly, Szabo denied that he had anything to do with Bitcoin’s creation publicly. Despite his denial, there is still a large part of the crypto community that still insists that he played a direct role in the creation of the world’s first cryptocurrency.

2009 Bitcoin

Bitcoin changed everything. The introduction of blockchain networks to the DLT sector was a huge advancement. It meant for the first time in history, a reliable and verifiable digital currency could function.

Notably, the birth of Bitcoin marks an uptick in DLT development globally. It provided a catapult for advancements in this sector. Today, these developments continue to usher in new and exciting DLT innovations.

Distributed Ledger Technology –  Today

In 2015, the blockchain platform Iota Introduced a DLT that could leverage the Internet of Things (IoT) for validation purposes. The IoT consists of every smart device in the world. In this new type of DLT, a protocol known as Tangle would allow the billions of smart devices around the world to verify network conditions. In essence, this development created the largest DLT in existence.

R3 Corda

Another major DLT development occurred with the introduction of R3’s Corda DLT. Importantly, Corda is not a blockchain. R3’s new system utilizes pluggable notaries to accomplish consensus. Interestingly, a single Corda network may contain multiple notaries that provide their guarantees using a variety of different algorithms. In this way, Corda is not beholden to any particular consensus algorithm.

Risks of Distributed Ledger Technology

As DLT becomes more common in the market, its important to understand that like all technology, there are some risks to keep in mind. DLTs are great at conveying and verifying data. However, there is no guarantee that this data entered the system correctly. One of the biggest issues facing these immutable ledgers is data input discrepancies.

Basically, DLTs rely on exact data to accomplish their tasks. If an employee enters in some part of this data incorrectly, it creates a ripple effect that can cascade down the network. These concerns mean that any DLT enabled firm must exercise caution to ensure all data entry occurs without errors. To accomplish this task, firms should exercise due diligence whenever they enter content into a DLT.

DLT – A Better Alternative

It’s easy to see why so many businesses continue to look towards DLTs as a way to streamline business functionalities. As such, you can expect to see DLTs become a core part of many business systems moving forward. For now, these unique networks have endless potential to alter the way the world conducts business.

What is DeFi (Decentralized Finance)?

mm

Updated

 on

Decentralized Finance (DeFi) is the merger of traditional bank services with decentralized technologies such as blockchain. DeFi can also go under the name Open Finance due to its inclusive format. Importantly, the DeFi community seeks to create alternatives to every financial service currently available. These services include items such as savings and checking accounts, loans, asset trading, insurance, and much more.

Importance of DeFi

DeFi continues to play an important role in the evolution of the financial sector for many reasons. For one, DeFi expands the functionality and reach of money. Since all you need to participate in the DeFi sector is a Smartphone, there is huge potential to expand the global economy. Consequently, analysts see this sector as one of the most important currently under development in the crypto space.

This commitment to the development of a DeFi ecosystem is easy to recognize. Importantly, DeFi is the fastest growing sector in blockchain. According to recent reports, DEFI tokens continually outperform their counterparts. Additionally, since this time period represents the beginning of this integration stage, the market now possesses the unique opportunity to see an entirely new industry blossom.

What are Dapps (Decentralized Applications)?

DeFi depends heavily on Dapps. To understand DeFi’s capabilities, you need to grasp the concept behind Dapps. Dapps are programs designed to function within decentralized networks. These networks can be blockchains, Tor networks, or Distributed Ledgers Technologies (DLT). The key component of these protocols is their decentralized nature. There is no central authority, corporations, or agency that monitors and approves the business functions of these applications.

Compound - DeFi Dapp

Compound – DeFi Dapp

In fact, Dapps require very little human intervention. Instead, these platforms integrate advanced smart contracts to streamline their business systems. Smart contracts are preprogrammed protocols that initiate upon receiving crypto to their address. Importantly smart contracts can handle a huge variety of tasks from customer approval to making payments.

Key Components of DeFi

Today, there are more DeFi apps than ever. These applications are already saving businesses and customer’s time and money. In fact, DeFi platforms have begun to emerge across nearly every financial sector. As the DeFi sector expands, it’s important to understand what characteristics all DeFi Dapps have in common. Here are the most common.

Open-Source

DeFi application should be open source. Open source coding refers to the fact that the coding is made public. In this way, anyone can audit it and validate its functionality, security, and capabilities. Open-source codes are far more stable and secure than private codes because of this community interaction. Additionally, it provides more confidence in the platform because users can rest assured that no hidden malicious coding is operating in the background.

Transparency

DeFi provides the world with new levels of transparency. Since most DeFi apps function on public blockchains such as Ethereum, all transactions are publicly available. In fact, all activity on the blockchain is public. The main difference in this approach versus a traditional bank account is that the accounts are not tied to anyone directly. Instead, accounts are pseudo-anonymous and only list a numerical address.

While the accounts are not directly linked to anyone’s name, in particular, there are ways for researchers to figure out who owns them if required. Programs such as block explorers can help people track and trace decentralized transactions of non-privacy focused coins.

Global Audience

Dapps represent an expansion in the way developers envision financial platforms. Anyone from around the world can participate in DeFi platforms. You just need a Smartphone with internet access and you can enter the DeFi community in minutes.

Consequently, DeFi Dapps have the ability to provide the unbanked of the world with access to financial services for the first time in recorded history. This openness is a huge upgrade from the current banking system that leaves around 40% of the global population without any form of banking.

Importantly, when you think of unbanked populations it’s easy to picture a village somewhere in the tropics or desert but the reality is much different. For example, a recent study found that 25% of US households remain unbanked. It’s in these locations that DeFi has an immediate effect.

Permissionless

The DeFi sector functions without gatekeepers. As such, anyone can develop a DeFi application and offer it to the world. Additionally, anyone can participate in DeFi Dapps without concern for approval. This strategy is far cry from today’s financial system that requires potential users to traverse a myriad of regulatory verification systems before they can participate in the global economy.

Interoperability

Another pillar of the DeFi community is interoperability. Interoperability is critical because it ensures that as more developers enter the space, all the previous work is not lost. Instead, users can stack their DeFi products to expand their exposure to this new age economy. For example, it’s common for a single user to utilize stablecoins, decentralized exchanges, and wallets together. This strategy is possible due to the seamless integration DeFi applications possess.

Flexibility

Due to the open nature of the DeFi environment, developers are able to exercise more flexibility in their platforms. Users gain considerable options through the integration of third-party application integrations as well. In fact, users can even choose to build their own interfaces if they find the current options insufficient.

DeFi in Lending

One of the sectors most affected by the introduction of DeFi is the lending sector. If you have ever applied for a loan, you know the process is time-consuming. Worst of all, you are forced to work with lending companies specially designed to maximize their returns. Luckily, the DeFi community has come up with some interesting ways to improve this market.

Compound

The Compound Dapp showcases the true power of DeFi and how it has the ability to transform how the world envisions the financial market’s role. Compound allows users to lend their crypto out to other users. In exchange for providing the loan, users receive interest in the form of cryptocurrency. Importantly, the platform utilizes smart contracts to match lenders and borrowers. Additionally, these smart contracts automatically make interest adjustments based on the market’s current state.

Decentralized Exchanges

Many consider decentralized exchanges as the logical next step in the evolution of the crypto sector. These peer-to-peer trading platforms provide users with a more streamlined UX , tighter security, and more flexibility. Traditional exchanges function via a centralized organization that facilitates, monitors, and approves all trades within the platform.

The problem with this approach is that it leaves too many attack vectors open. Hackers can target the exchange and make off with millions. A quick Google search demonstrates numerous examples of exchange hacks in which the central organization suffered huge losses. In many instances, these firms were forced to discontinue operations due to the losses.

Binance DEX via Homepage

Binance DEX via Homepage

Decentralized exchanges eliminate many of these concerns. When a user exchanges an asset via a decentralized exchange, the platform never holds the assets directly. Instead, smart contracts are used to enable a simultaneous wallet-to-wallet swap. In this way, there is no main point of weakness within the platform for a hacker to exploit.

Uniswap

The Uniswap platform introduced an innovative mechanism known as Automated Market Making. This protocol enables near-instant settlement between parties. Importantly, the protocol is set to close trades as close to the current market value as possible. You can even lend out your crypto and earn some interest via the platform’s Pooling feature.

New Age Savings with DeFi

DeFi enables some of the most basic financial actions to regain a new life. For example, the PoolTogether Dapp is a platform that savers can meet up at and participate in a no-loss game. In the game, everyone deposits crypto into an interest gaining wallet. At the end of the month, one lucky winner walks away with all of the interest earned. Amazingly, everyone else leaves with their initial investment in place.

DeFi Prediction Platforms

Another interesting development in the sector is the birth of prediction platforms. A prediction platform is used to analyze the current public opinion of a certain event. Tapping into the wisdom of the masses can be a valuable tool for businesses seeking more market insight.

Guesser

The platform Guesser allows you to make predictions and examine the results of others in the pool. Critically, you even earn crypto for your participation. Simply put an amount with your prediction, if you are right, you earn extra crypto for your wisdom.

How DeFi is Here to Stay

As the main systems of our society undergo a transformation towards decentralization, there will be more demand for DeFi Dapps in the future. These new-age applications continue to disrupt the current business systems in remarkable ways.

Soon, decentralized applications will set the new standard for the economy moving forward. Consequently, the global economy could receive a huge boost in participation in the coming years. For now, DeFi provides the world with a glimpse into a more democratic existence.

What are Dapps (Decentralized Applications)?

mm

Updated

 on

Decentralized applications (Dapps) continue to change the world around us in remarkable ways. These new-age programs provide users with more functionality and security than ever. Additionally, these applications feature a robust design that is meant to leverage the decentralized nature of blockchain technology. As such, these programs run on a blockchain or P2P network of computers instead of a single computer.

Dapps are Decentralized

When you think of a traditional software program like MSWord, it’s important to understand that the protocol resides on a single computer system. Even if you are using the online version, the actual software is operated by a central organization, in this case, Microsoft. Consequently, Microsoft has full control over the application and its use.

This control provides the group with full authority over the app. Importantly, centralized apps, such as Facebook, require this style of structuring to function correctly. The organization plays a pivotal role in these software systems. If it was attacked, damaged, or removed for any reason, the system would fail to operate.

This is why Dapps are decentralized.

Dapp Characteristics

While Dapps can come in all shapes and sizes, they all share some common factors. Firstly, all Dapps are decentralized. Decentralization implies that all the application’s operations must be stored on a public blockchain. Next, Dapps incentivize users to participate in their network. In most instances, these incentives include payment via some form of cryptocurrency. It’s very common for the application to create a native utility token to facilitate this process.

Dapps Create New Business Opportunities

Dapps Create New Business Opportunities

Paramountly, Dapps utilize some form of a consensus mechanism to ensure the validity of the network. In a consensus mechanism, the network’s participants act as validators. They are also known as nodes or miners because they receive a reward for their efforts, like mining for gold. Nodes are who validates new transactions. Additionally, one of the nodes eventually is who gets to add the next “block” to the “chain” of transactions.  Ideally, a Dapp will also feature an open-source protocol.

Dapps and P2P Networks

All Dapps run on either a P2P network or a blockchain network. A P2P network is a network that allows users to exchange data and services directly.  In the case of websites, you can think of streaming websites such as Popcorn Time. When users enter the Popcorn Time P2P Tor network they receive access to a variety of other users who are offering downloads. The user then chooses which user to download the data from and a direct connection is established between the two parties.

Blockchain P2P

In a blockchain network, there is no central point of control. There is no company that ensures the blockchain is running correctly. Instead, every computer on the network works together to secure the network.  In most instances, the software is open source. Open-source software is generally more secure because it allows the community o test its capabilities. In this way, blockchain technology creates a truly decentralized experience for participants.

Dapps vs. Regular Apps

To put the power of Dapps in perspective, let’s imagine that you just placed a post for your new political book on Facebook. However, when you go back to check on the stats for your post just a few hours later, you realize the post was removed because your book’s content violated Facebook’s new terms of service.

In its centralized network, Facebook is the entity in control of the network. In other words, they are the king of the content provided. If they deem that what you have to say doesn’t fit into their narrative, they have every right to kick you out of the platform. The same way you could ask someone to leave your home if you disapproved of their conduct.

Dapps function much differently. If Facebook is like your home, think of Dapps as a public park. There is no central governing authority to tell you that your post must go. In fact, due to the immutable nature of blockchain technology, your post about your book will never come down.

Dapps Current Applications

The first Dapp to enter the market with success was Bitcoin. As such, Bitcoin is a self-sustaining public ledger. It is immutable and decentralized. Even more important, is the fact that Bitcoin entered the market as a direct response to the centralization experienced within the traditional financial sector.

Ethereum Changed the Game

If Bitcoin lit the Dapp candle, Ethereum poured gas on it. Ethereum’s whitepaper states that this cryptocurrency is a “protocol for building decentralized applications.” Every aspect of Ethereum’s network focuses on reducing development time, improving security, and ensuring scalability.

Ethereum Whitepaper

Ethereum Whitepaper

Ethereum changed the Dapp game forever. This unique platform introduced a new programming language specifically to simplify Dapp programming. Additionally, Ethereum developers can utilize the Turing-complete Ethereum Virtual Machine (EVM) to create smart contracts in minutes.

Brave New Browser

Today Ethereum Dapps dominate the market. Applications such as the Brave New Browser utilize ERC-20 compliant tokens to accomplish some amazing things. In the case of the next-generation browser Brave, users receive BAT tokens for their participation. Brave users actually receive payment for their data. Additionally, they gain far more control over their information. Users can decide who, when, and what to share. In this way, the Dapp Brave is revolutionizing what it means to surf the net.

STORJ

In another perfect example of the added capabilities that Dapps bring to the market, the platform STORJ allows users to rent out their unused computer space. The application helps users and those seeking more storage meet up and exchange services. In the end, one party receives computer storage capabilities at a fraction of the normal market costs, while the other party earns cryptocurrency for providing the space.

Summary – Dapps Potential

The future potential for Dapps is undeniable. Every week, new and exciting projects emerge in the market. As such, you should expect to continue to see these protocols integrated into every business sector over the coming years.

What is Blockchain Technology?

mm

Updated

 on

Its been almost ten years since Satoshi Nakamoto first introduced Blockchain technology to the world in his 2008 Bitcoin Whitepaper. Since that time, these revolutionary networks have gained popularity in both the corporate and governmental sectors. This growth is easily explained when you consider that blockchain technology provides the world with some unique advantages that were previously unimaginable. Consequently, today, you can find blockchain technology in nearly every sector of the global economy.

What is Blockchain Technology?

A blockchain is a network of computers that share a distributed ledger across all network participants (nodes). This strategy is far different than say, fiat currencies that originate from a centralized authority figure. Importantly, this ledger keeps an unbroken chain of transactions since the birth of the network. This “chain” of transactions grows larger as new “blocks” of transactions are approved and added to it.

Bitcoin Whitepaper

Bitcoin Whitepaper

In order to approve new transactions, each node works together with others to validate new blocks. Additionally, the nodes also validate the current state of the entire blockchain. In order for a new block of transactions to be added to the blockchain, they must receive approval from 51% of the network’s nodes. Nodes are also referred to as miners. In this manner, blockchain networks are decentralized networks that provide unmatched security to the world of digital assets.

Security via Decentralization

Decentralization is an important aspect of blockchain technology because it makes these revolutionary ledgers immutable and unalterable. In fact, since there is no centralized attack vector, hacking a blockchain is nearly impossible. The larger the blockchain network, the more secure the data on it remains.

For example, let’s look at the world’s largest blockchain, Bitcoin. Currently, the Bitcoin blockchain has over 10,000 active nodes located across the globe. This distribution means that in order for an attacker to alter even just one tiny piece of information on the blockchain, they would need to successfully hack 5,000+ computers at once.

While this task may not be impossible for the quantum computers of the future, it’s so unprofitable that it makes no sense to even attempt such a monumental task. Additionally, on top of successfully hacking 5000+ computers at once, an attacker would also need a supercomputer to recalculate the new blockchain transactions in time to introduce them into the network. It would literally be more affordable to create a new cryptocurrency from scratch.

Consensus Mechanisms

One of the reasons why blockchain networks are so secure is the integration of consensus mechanisms. Consensus mechanisms are cryptographic protocols that leverage the participants of a blockchain network in securing its data. In the case of Bitcoin, the Proof-of-Work (PoW) consensus mechanism is used.

Proof-of-Work (PoW)

The Proof-of-Work consensus mechanism was revolutionary to the world of cryptography when it was first introduced years prior by Adam Back in his Hashcash whitepaper. In the concept, Back describes the integration of a mathematical equation to the network’s security protocols. In this way, every computer can show “proof” of their work securing the network.

Miner Rewards

It’s important to understand that nodes receive a reward for their mining efforts. These rewards adjust automatically depending on the network’s difficulty and value. In the case of Bitcoin, miners originally received 50 Bitcoin for their efforts. Today, this seems like fortune, but back in 2009, Bitcoin was only worth pennies. As the value of the token rises and the network goes, the mining rewards shrink. Today, Bitcoin miners receive 6.5 BTC if they add the next block to the chain.

SHA-256

Notably, every node validates and secures the blockchain, but only one gets to add the next block of transactions to the network. To determine who the next miner is that gets to add this block, every computer competes in a mathematical race to figure out the PoW equation. In the case of Bitcoin, the equation is known as SHA-256. Importantly, the first SHA algorithm dates back to Hashcash. This early version of the equation was known as SHA-1.

Bitcoin Consensus Mechanism - SHA-256 - Blockchain Technology

Bitcoin Consensus Mechanism – SHA-256 – Blockchain Technology

Notably, the SHA-256 equation is so difficult that it’s easier and more efficient for your computer to just make random guesses rather than attempting to figure out the equation directly. The answer to the equation must begin with a predetermined amount of 0s. In the Bitcoin blockchain, the equation’s answer must start with four zeros. However, if the network’s congestion rises, so does the difficulty of these equations. This difficulty adjusts by the addition of another zero at the beginning of the required SHA-256 answer.

Similarly to traditional commodities such as gold, there are costs that are associated with the creation and introduction of these digital assets into the market. These random guesses utilize intense computational power. This power equates to real-world costs such as electricity bills. Studies have shown that securing the Bitcoin network can use more electricity than required by entire countries. Luckily, over 80% of Bitcoin’s power consumption comes from renewable sources such as solar or hydroelectric.  This cost of mining also adds measurable value to each Bitcoin.

Miners

As Bitcoin began to gain in profitability,  its network’s computing power expanded significantly. In the beginning, nodes, also known as miners, could mine for Bitcoin using nothing more than your home PC. Eventually, miners realized that graphic cards were far better at the repetitive guessing required to figure out the SHA-256 algorithm. This led to a computational race in the market.

ASIC

Eventually, large blockchain firms such as Bitmain introduced Application Specific Integrated Circuit (ASIC) miners into the equation. These purpose-built miners were thousands of times more efficient at guessing the SHA-256 algorithm than the GPUs and CPUs before them. Consequently, their introduction created a scenario in which the average miner now needed to invest thousands in mining equipment to stay relevant.

Mining Pools

Luckily, some creative minds in the field began to think of ways to level the playing field out again. They developed “mining pools.” A mining pool is a network of miners that all share computational power for the common goal of mining blockchain transactions. Importantly, mining pool participants receive a percentage of the reward based on their contributions to the network’s overall hash (computational power).

Importantly, over the last three years, there has been a push to move away from power-hungry consensus mechanisms such as PoW. This desire to secure blockchains in a more efficient manner has led to the development of some truly unique consensus mechanisms in the sector.

Proof-of-Stake (PoS)

The Proof-of-Stake mechanism does away with the difficult mathematical algorithms and instead utilizes a more psychological approach to securing the network. In a PoS blockchain, users don’t need to compete mathematically to add the next block to the blockchain. Instead, PoS users “stake” their coins via network wallets to secure the network. The way staking works is simple.

Keeping a certain amount of coins in your wallet allows you to participate in transaction validations. The more coins you stake, the more likely the chances are you get to add the next block of transactions to the network. In most PoS systems, a miner from those with the most tokens staked at the time receives the chance to add the blocks.

The advantages of a PoS consensus mechanism are immediately evident. For one, you don’t need to pour tons of resources into your network to keep it safe. Additionally, since nodes are chosen based on their amount of staked coins, there is never a scenario in which a node gains anything from validating incorrect transactions. Basically, a hacker would have to fully invest in the cryptocurrency prior to attacking the network. In this way, PoS systems create a huge deterrent to attackers.

The Future of Blockchain Technology

Blockchain technology has come a long way from its early days as a means to secure cryptocurrency networks. Today, blockchain technology has numerous uses across every type of industry imaginable. Specifically, blockchain programs have impacted the logistical, financial, and data security sectors in a major way.

Blockchain Technology Logistics

Blockchain logistical systems are more efficient and cost-effective to operate than traditional paper-based models. In fact, the immutable and unalterable nature of blockchain tech makes it ideally suited to logistical tasks. Soon, you may be able to ascertain much more information regarding the creation and delivery of your products thanks to these new-age systems emerging.

Fundraising

Blockchain technology has also altered the way in which businesses raise funds. In a traditional corporate crowdfunding strategy such as an IPO, companies must balance between cost-effectiveness and participation. The inability to process smaller transactions meant that for the longest time, companies had to turn away potential investors. Nowadays, blockchain technology enables businesses to easily automate these procedures via smart contracts.

Smart Contracts

Smart Contracts feature preprogrammed protocols that execute when they receive a certain amount of cryptocurrency sent to their address. These contracts live on the blockchain and enable remarkable functionality. For example, in the case of fundraising, a smart contract can automate processes such as the approval of investors and the distribution of funds.

Blockchain Technology Today

You can expect to see further expansion of the blockchain sector in the coming months as more governments and institutions explore its benefits. For now, the blockchain revolution is well underway.
