What is an Initial Coin Offering (ICO)?

An initial coin offering (ICO) is a sort of capital-raising activity for cryptocurrency projects in their early stages.

During an ICO, a blockchain-based firm creates a limited number of its own native digital tokens and sells them to early investors.

While ICOs can provide a simple fundraising method and an innovative way for entrepreneurs to acquire funds, investors can also profit from both access to the service provided by the token and an increase in the token’s price if the platform is successful.

The primary benefit of ICOs is that they avoid intermediaries from the capital-raising process and establish direct relationships between the corporation and investors.

Furthermore, both sides’ interests are linked.

An initial coin offering (ICO) is a fundraising event in which a firm offers a new cryptocurrency.

Origins

It all started in 2013, when J.R. Willet, a software engineer, authored a white paper titled “The Second Bitcoin White Paper” for the token MasterCoin and raised $600,000.

Seven initiatives have raised a total of $30 million by 2014.

Ethereum was the largest that year, with 50 million ether minted and sold to the public, generating more over $18 million.

2015 was a more sedate year. A total of $9 million was raised through seven transactions.

In 2016, 43 ICOs raised $256 million, kicking off a surge in activity.

ICOs reached a new high in 2017, thanks in part to technical developments.

The issue of 342 tokens raised about $5.4 billion, propelling the idea to the forefront of blockchain innovation.

Telegram completed the biggest ICO to date. The UK-registered corporation raised almost $1.7 billion in a private ICO.

Types

  1. Private ICO: Only a small number of investors are permitted to participate in the process. Private ICOs often allow only accredited investors to participate, and a corporation might opt to establish a minimum investment amount.
  2. Public ICOs: A type of crowdfunding aimed at the whole public. Because almost anyone can become an investor in a public offering, it is a democratized form of investing.

How does an ICO Work?

When a corporation decides to hold an ICO, it publishes the date, regulations, and purchasing procedure ahead of time. Investors can purchase the new coin on the ICO date.

The majority of ICOs need investors to pay using another cryptocurrency, with Bitcoin and Ethereum being two popular options. There are ICOs that accept fiat money as well.

Typically, the purchasing procedure is transferring money to a specific crypto wallet address. Investors specify their own recipient address in order to get the cryptocurrency they purchase.

During an ICO, the quantity of tokens sold and the token price might be fixed or flexible.

  • Fixed number of tokens and price: The corporation determines both in advance, for example, selling one million tokens at a price of $1 per token.
  • Fixed number of tokens and a variable price: The corporation sells a fixed number of tokens and charges a variable price dependent on the amount of cash received.

A greater token price stems from more investment. If it sells one million tokens and raises $2 million, each token will cost $2.

  • Variable number of tokens and a fixed price: The corporation has a fixed price but does not limit the amount of tokens sold. As an example, suppose a corporation sells tokens for $0.50 each until the ICO concludes.

An ICO can be launched by anybody. Many new forms of cryptocurrencies are launched using this procedure due to the low barrier to entry.

ICO vs. IPO

ICOs are sometimes contrasted with initial public offerings (IPOs), which are fresh stock offerings by a private firm. Companies can raise capital through both ICOs and IPOs.

The fundamental distinction between ICOs and initial public offerings (IPOs) is that IPOs include the sale of securities and are subject to substantially tougher laws.

To launch an IPO, a firm must file a registration statement with the Securities and Exchange Commission and obtain its approval. A prospectus containing financial statements and possible risk factors should be included with the registration statement.

An initial coin offering (ICO) is the selling of a cryptocurrency rather than a securities. As a result, it lacks the formal criteria that IPOs do. However, if a corporation tries to circumvent the rules by holding an ICO for anything that meets the definition of a security, it may face legal consequences.

Advantages and Disadvantages

Online services may help with the creation of cryptocurrency tokens, making it extremely simple for a business to contemplate launching an ICO.

ICO managers produce tokens in accordance with the conditions of the ICO, receive them, and then distribute the tokens to individual investors by transferring the coins.

However, because ICOs are not regulated by financial institutions such as the SEC, monies lost due to fraud or ineptitude may never be recovered.

Early investors in an ICO are typically driven by the anticipation that the tokens will appreciate in value once the coin is launched. The prospect for extremely large profits is the key advantage of an ICO.

However, the legality of cryptocurrencies or digital assets is not assured.

The People’s Bank of China formally outlawed ICOs in 2017, deeming them harmful to economic and financial stability. In 2021, the Chinese government banned bitcoin mining and made all cryptocurrency transactions illegal.

What is a Crypto Token?

What is a Crypto Token?

Token is a term that is frequently heard in the cryptocurrency community. In fact, you may hear Bitcoin referred to as a “crypto token” or something similar, because – theoretically – all crypto assets may be referred to as tokens.

Crypto tokens are programmable assets that may be created and stored on current blockchains. While they frequently have extensive compatibility with the network’s cryptocurrencies, they are a whole new digital asset class.

Tokens are units that are built on top of existing blockchains.

Tokens function within an existing blockchain to enable the development and execution of one-of-a-kind smart contracts, which frequently provide ownership of assets outside of the blockchain network. Tokens may be sent and received and can represent units of value such as electricity, money, points, coins, digital assets, and more.

Crypto tokens are a sort of cryptocurrency that symbolizes an item or a specific use and has its own blockchain.

How Crypto Tokens work?

To monitor transactions, blockchain employs a decentralized, or distributed, ledger that lives on a broad variety of independent computers. Each node organizes additional data into blocks, which are then chained together in “append only” mode. Because of the append-only structure, no one on any node can change or remove data from previous blocks. They can only contribute to the chain, which is one of blockchain’s primary security characteristics.

Cryptocurrency tokens provide an append-only safe record of cryptocurrency that is linked to a special-access contract that can connect to a variety of assets.

The token-based special-access contract can grant users access to assets like as cash, crypto coins, reward points, or even digital material such as music, art, a video clip, or a movie.

The tokens enable the ownership of a blockchain-verified private smart contract linked to that asset.

Coins Vs Tokens

While the terms “coin” and “token” are sometimes used interchangeably, they refer to different sorts of assets.

A crypto coin is often employed as the native coin of a blockchain, which is used to exchange cash, store value, and so on. Tokens, on the other hand, are not native to the blockchain on which they operate.

Crypto Token Types

Currently, there are four main categories of tokens

  • Payment Tokens: Payment tokens are the most well-known and extensively utilized types of cryptocurrency. These crypto tokens are used for buying and selling in the same way that the US dollar or the Euro are, only they are not backed by a specific government. Payment tokens are units of value that may be traded for other currencies that exist within the blockchain of crypto networks such as Bitcoin, Monero, and Ethereum. Third-party custodians or exchanges are also available to convert payment tokens into legal tender currencies such as the US dollar. People are increasingly utilizing these tokens to purchase products and services, albeit the aggregate number of retailers who accept them remains tiny.
  • Utility Tokens: These crypto tokens provide its owners with access to a product or service that is either now available or in the works. They are most typically employed as a fundraising mechanism for initial coin offers (ICOs), as a placeholder for the crypto currencies that buyers would get when the new coins go live on the network. The term for these tokens stems from the fact that they may be used to purchase an item or service from the issuer. Because they exist on an actual blockchain, their owners can be confirmed, and they can be readily swapped.
  • Security Tokens: Security tokens represent the rights and duties associated with securities such as stocks and bonds. A security token is often used to represent a stake of the firm that issued it. They can reflect legal ownership of an asset or a piece of an asset, such as real estate, stocks, exchange-traded funds (ETFs), and so on.

As a result, they are more strictly controlled than ordinary tokens. Companies may issue security tokens instead of traditional stock shares to raise funds more cheaply, or because the tokens provide immediate settlement and simpler cross-border trade.

  • Non-fungible Tokens: Also known as NFTs, these tokens have made the news lately because of the eye-popping sales prices of single NFTs connected with works of art, individual tweets, and sports memorabilia. They exist on pre-existing crypto networks, with ETH being one of the most popular. These tokens have private contracts that can be clearly distinguished from any other token in existence. Because of that feature, they are used by athletes, artists, musicians, and other creators as a way to connect with collectors, who see them as digital one-of-a-kind assets. Because the consumer may still reproduce the underlying material, they cannot copy, sell, or pirate it, NFTs have created new marketplaces for digital art and memorabilia. Some persons have also issued NFTs that provide ownership of non-digital assets that are one-of-a-kind, such as real estate.


Tokens can be used for investment purposes, to store value, or to make purchases.

The Takeaway

As the blockchain industry matures, the number of distinct digital assets will only increase to meet the diverse demands of all ecosystem members, ranging from business partners to individual users. Given that generating new assets in the digital world is less limiting than in the physical realm, these digital assets are widely predicted to change the way many sectors work, interact, and produce value, enabling a plethora of new social and economic possibilities.

What is HODL?

What is HODL?

HODL is a commonly used slang phrase in the Bitcoin and other cryptocurrency circles. Some individuals mistakenly believe that HODL is an abbreviation for “Hold on for Dear Life.” While the term is correct, it represents a little of revisionist history.

It turns out that HODL is a drunken misspelling of the word “hold.”

Origin

The word “HODL” first appeared in 2013 in a post to the Bitcointalk forum by an excited member named GameKyuubi. Bitcoin’s price was turbulent throughout 2013, soaring to over $1,100 at the start of December 2013, up from just over $100 in April of the same year.

In his post, he wrote, “I AM HODLING,” implying that from that moment on, he would merely retain his bitcoins rather than sell it, regardless of market conditions. Within hours, the error had made its way into every Bitcoin community channel in the form of jokes and GIFs, launching HODLing into crypto-jargon history.

HODL post

Strategy and Philosophy

HODL has become a crypto enthusiast’s catchphrase, suggesting a long-term strategy to cryptocurrency investing.

This method is consistent with GameKyuubi’s reasoning in the original article, which said that rookie traders are likely to fail in their attempts to play the market and should instead simply hold their currency.

For bitcoin maximalists, HODL is more than just a method for dealing with FOMO (Fear of Missing Out), FUD (Fear, Uncertainty, and Doubt), and other profit-depleting emotions.
Long-term cryptocurrency investors remain involved because they think that cryptocurrencies will eventually replace government-issued fiat currencies as the foundation of all economic organizations.
If this happens, the exchange rates between cryptocurrencies and fiat money would become meaningless to crypto holders.

Risks

Despite the recent high rate of return and the motivations to buy, smart investors should be aware of the hazards associated with cryptocurrency holdings. Cryptocurrency prices are quite volatile.

Investors may have to deal with severe ups and downs in asset values, which implies they must have far higher risk tolerances than investors in traditional financial products. They must have enough capital to avoid forced sales or to cover unanticipated liquidity demands.

With a relatively limited history in comparison to other forms of assets and fiat currencies, cryptocurrencies face an uncertain future. The cryptocurrency policy is still in its early stages. Cryptocurrencies can be used for fraudulent activities such as illicit transactions and money laundering if they are not monitored by a central body.

Different governments and political groups have expressed varying views on the usage of cryptocurrencies. It has the potential to greatly impede their function in enabling international transactions, hence lowering the value of cryptocurrencies. Unfavorable policymaking and public perception may have a long-term negative impact on asset value.

Token

$HODL is a cryptocurrency that was called after the popularity of the word “HODL” in the crypto community. The Binance Smart Chain is used by the HODL token, and HODL token owners can receive Binance Coin incentives.

What is Proof of Work (PoW)?

What is Proof of Work?

Proof of work, commonly abbreviated as PoW is the oldest method of consensus. A consensus algorithm is, in general, a decision-making process within a group.

A PoW algorithm works in such a way that nodes within a network proves to others (the verifiers) that a certain amount of a specific computational effort has been expended. Verifiers can subsequently confirm this expenditure with minimal effort on their part.

The goal of PoW algorithms is not to prove that specific work was done or that a computational issue was “solved”, but to discourage data modification by imposing high energy and hardware-control requirements.

Origin

Cynthia Dwork and Moni Naor introduced the notion in 1993 as a technique to combat denial-of-service (DOS) attacks and other service abuses such as spam on a network by requiring some work from a service requester, often processing time by a computer.

Markus Jakobsson and Ari Juels invented and standardized the term “proof of work” in a 1999 publication. PoW was later popularized by Bitcoin as the basis for consensus in a permissionless decentralized network in which miners compete to add blocks and mint new money, with each miner having a success probability proportionate to the computing effort exerted.

Why is PoW necessary?

The problem with a blockchain, such as Bitcoin, is to keep an agreed-upon transaction record in the absence of a central authority. So, the main challenge is how a group of peers with comparable status can agree on who should be permitted to contribute to the shared record. PoW is how miners (block publishers) demonstrate to the rest of the world that they have put in the effort required to construct a well-formed block of transactions to add to the blockchain.

PoW is significant because it provides evidence of confidence in a trustless environment.

This protocol ensures that excessive mining does not occur. This is accomplished by increasing the complexity of confirming each block.

It preserves the cryptocurrency’s supply while also assisting miners in keeping the network operational. At the same time, it makes use of limited resources such as time, processing power, and energy.

How does the PoW work?

The working of PoW protocol can be summarized in brief as follows

  1. The transactions are bundled together into units generally known as blocks.
  2. The transactions within each block are verified for legitimacy by the miners.
  3. A mathematical puzzle known as the proof-of-work problem has to be solved by the miners to account for verification.
  4. The first miner who solves each block problem is being rewarded.
  5. Then the verified transactions are stored in the public blockchain.

Benefits

There are several advantages to using PoW systems. They are an excellent method of discouraging spammers. If a fair amount of effort is required for each procedure, such as sending an email, most spammers will not have the processing power to send a significant number of unwanted emails.

Furthermore, PoW frameworks may be utilized to safeguard a whole network. This is the key benefit of blockchains that use a consensus approach for PoW. If enough nodes compete to discover a certain solution, the processing power necessary to overwhelm and dominate a network becomes unattainable for any one bad actor or even a single group of bad actors.

Limitations

  • Huge expenditures: There is a need for specialized computer hardware to run complicated algorithms for mining. The cost is also high and not affordable. In addition, the special mining pools need a massive amount of power to run, which further alleviates the cost.
  • The uselessness of computations: There is a lot of power required for the machines to generate a block by the miners. however, their estimates are not valid anywhere else, such as a company, science, or others.
  • 51% attack: A 51% attack is a PoW attack by the majority of the group of users, who controls the majority of the mining power. The attackers come in complete power, where they can monopolize by creating blocks and receive rewards.

Conclusion

The initial answer to the problem of double-spending was PoW, which has shown to be accurate and successful.

In the PoW, all miners are expected to compute a difficult sum. The winner is also selected by the individual who possesses the most hardware gadgets.

However, there are several flaws with the PoW method that must be addressed. This contains the quantity of energy required, the present concentration of power in mining pools, and the hazards of a 51 percent attack. The winner is also chosen by who possesses the most hardware equipment.

What is Blockchain?

What is Blockchain?

Blockchain is a system of recording information.

Technically speaking, it is a distributed database shared between the nodes of the network mainly through internet. As a database, stores information electronically in digital format.

One key difference between a typical database and a blockchain is how the data is structured. A database usually structures its data into tables, whereas a blockchain, like its name implies, structures its data into chunks, called blocks.

This data structure inherently makes an irreversible timeline of data when implemented in a decentralized nature. When a block is filled, it is set in stone and becomes a part of this timeline. Each block in the chain is given an exact timestamp when it is added to the chain.

Cryptography is used to connect the blocks. A cryptographic hash of the preceding block, a timestamp, and transaction data are all included in each block. The timestamp verifies that the transaction data was there at the moment the block was released, allowing it to be hashed. Because each block contains information about the previous block, they create a chain, with each new block strengthening the previous ones.

As a result, blockchains are resistant to data tampering since the data in any one block, once recorded, cannot be changed retrospectively without affecting all subsequent blocks.

The innovation with a blockchain is that it guarantees the fidelity and security of a record of data and generates trust without the need for a trusted third party.

Origin

Blockchain technology was first outlined in 1991 by Stuart Haber and W. Scott Stornetta, two mathematicians who wanted to implement a system where document time stamps could not be tampered with. In the late 1990s, cypherpunk Nick Szabo proposed using a blockchain to secure a digital payments system, known as bit gold (which was never implemented).

How does blockchain work?

The goal of blockchain is to allow digital information to be recorded and distributed, but not edited. In this way, a blockchain is the foundation for immutable ledgers, or records of transactions that cannot be altered, deleted, or destroyed. Therefore, blockchains are also known as a distributed ledger technology (DLT).

Private vs public blockchain

A public blockchain, also known as an open or permissionless blockchain, is one where anybody can join the network freely and establish a node. Because of its open nature, these blockchains must be secured with cryptography and a consensus system like proof of work (PoW).

A private or permissioned blockchain, on the other hand, requires each node to be approved before joining. Because nodes are trusted, the layers of security do not need to be as robust.

Uses

Blockchain technology can be integrated into multiple areas. The primary use of blockchains is as a distributed ledger for cryptocurrencies such as Bitcoin; there were also a few other operational products which had matured from proof of concept by late 2016.

  • Cryptocurrencies: Most cryptocurrencies use blockchain technology to record transactions.
  • Smart contracts: Blockchain-based smart contracts are proposed contracts that can be partially or fully executed or enforced without human interaction. One of the main objectives of a smart contract is automated escrow. A key feature of smart contracts is that they do not need a trusted third party to act as an intermediary between contracting entities -the blockchain network executes the contract on its own. This may reduce friction between entities when transferring value and could subsequently open the door to a higher level of transaction automation.
  • Financial services: Many banks have expressed interest in implementing distributed ledgers for use in banking and are cooperating with companies creating private blockchains.
  • Anti-counterfeiting: Blockchain could be used in detecting counterfeits by associating unique identifiers to products, documents and shipments, and storing records associated to transactions that cannot be forged or altered. It is however argued that blockchain technology needs to be supplemented with technologies that provide a strong binding between physical objects and blockchain systems.
  • Healthcare: In response to the 2020 COVID-19 pandemic, The Wall Street Journal reported that Ernst & Young was working on a blockchain to help employers, governments, airlines and others keep track of people who have had antibody tests and could be immune to the virus. Hospitals and vendors also utilized a blockchain for needed medical equipment.

Advantages of blockchain

  • Accuracy of the chain: Transactions on the blockchain network are approved by a network of thousands of computers. This removes almost all human involvement in the verification process, resulting in less human error and an accurate record of information. Even if a computer on the network were to make a computational mistake, the error would only be made to one copy of the blockchain. For that error to spread to the rest of the blockchain, it would need to be made by at least 51% of the network’s computers
  • Decentralization: Blockchain does not store any of its information in a central location. Instead, the blockchain is copied and spread across a network of computers. Whenever a new block is added to the blockchain, every computer on the network updates its blockchain to reflect the change. By spreading that information across a network, rather than storing it in one central database, blockchain becomes more difficult to tamper with. If a copy of the blockchain fell into the hands of a hacker, only a single copy of the information, rather than the entire network, would be compromised.
  • Cost Reductions: Typically, consumers pay a bank to verify a transaction, a notary to sign a document, or a minister to perform a marriage. Blockchain eliminates the need for third-party verification — and, with it, their associated costs
  • Immutable: Any validated records are irreversible and cannot be changed.
  • Anonymous: The identity of participants is either anonymous or pseudonymous.
  • Efficient transactions: Transactions placed through central authority can take up to few days to settle. If you attempt to deposit a check on Friday evening, for example, you may not actually see funds in your account until Monday morning. Whereas financial institutions operate during business hours, usually five days a week, blockchain is working 24 hours a day, seven days a week, and 365 days a year.

Disadvantages of blockchain

  • Technology cost: Although blockchain can save users money on transaction fees, the technology is far from free. For example, the PoW system, which the Bitcoin network uses to validate transactions, consumes vast amounts of computational power. In the real world, the power from the millions of computers on the Bitcoin network is close to what Denmark consumes annually.
  • Speed and data inefficiency: Bitcoin is a perfect case study for the possible inefficiencies of blockchain. Bitcoin’s Pow system takes about 10 minutes to add a new block to the blockchain. At that rate, it’s estimated that the blockchain network can only manage about seven transactions per second, (TPS). Legacy brand Visa, for context, can process 24,000 TPS.
  • Illegal activity: While confidentiality on the blockchain network protects users from hacks and preserves privacy, it also allows for illegal trading and activity on the blockchain network.

What is Ethereum?

What is Ethereum?

Ethereum is an open-source decentralized blockchain-based platform that allows individuals to conduct transactions and draw up contracts.

It has its own cryptocurrency, called Ether, and its own programming language, called Solidity.

As a blockchain network, Ethereum is a decentralized public ledger for verifying and recording transactions. The network’s users can create, publish, monetize, and use applications on the platform.

The most fascinating aspect of Ethereum is that the code published on its blockchain cannot be changed, modified, or hacked.

It is a decentralized programmable blockchain-based software platform, not simply a blockchain.

Ethereum was established in the summer of 2015 with the goal of broadening the spectrum of blockchain and cryptocurrency applications beyond Bitcoin’s initial scope, including permissionless financial services, crowdfunding, and new organizational structures.

Origin

Ethereum was initially described in a white paper by Vitalik Buterin, a programmer, in late 2013 with a goal of building decentralized applications.

Buterin argued to the bitcoin core developers that Bitcoin and blockchain technology could benefit from applications other than money, and that a more robust language for application development was needed, which could lead to the blockchain being used to store real-world assets like stocks and property. He recommended the construction of a new platform with a more sophisticated programming language, which would later become Ethereum, after failing to reach agreement on how the project should proceed.

Formal development of the software began in early 2014 through a Swiss company. The basic idea of putting executable smart contracts in the blockchain needed to be specified before the software could be implemented.

Several codenamed prototypes of Ethereum were developed over 18 months in 2014 and 2015 by the Ethereum Foundation as part of their proof-of-concept series.

In July 2015, “Frontier” marked the official launch of the Ethereum platform as Ethereum created its “genesis block.”

Since the initial launch, Ethereum has undergone several planned protocol upgrades, which are important changes affecting the underlying functionality and/or incentive structures of the platform.

After the Constantinople upgrade on 28 February 2019, there were two network upgrades made within a month late in the year: Istanbul on 8 December 2019 and Muir Glacier on 2 January 2020.

There have been two network upgrades in 2021. The first was the Berlin upgrade, implemented on 14 April 2021. The second was London, which took effect on 5 August. The London upgrade included Ethereum Improvement Proposal (“EIP”) 1559, which introduced a mechanism for reducing transaction fee volatility. The mechanism causes a portion of the Ether paid in transaction fees each block to be destroyed rather than given to the miner, reducing the inflation rate of Ether and potentially resulting in periods of deflation.

How does Ethereum work?

You might have heard that the Bitcoin blockchain is a lot like a bank’s ledger, or even a checkbook. It’s a running tally of every transaction made on the network going back to the very beginning — and all the computers on the network contribute their computing power towards the work of ensuring that the tally is accurate and secure.

The Ethereum blockchain, on the other hand, is more like a computer: while it also does the work of documenting and securing transactions, it’s much more flexible than the Bitcoin blockchain. Developers can use the Ethereum blockchain to build a huge variety of tools — everything from logistics management software to games to the entire universe of decentralized applications (which span lending, borrowing, trading, and more).

Ethereum uses a virtual machine to achieve all this, which is like a giant, global computer made up of many individual computers running the Ethereum software. Keeping all of those computers running involves investment in both hardware and electricity by participants. To cover those costs, the network uses its own cryptocurrency, Ether (or, more commonly, ETH).

ETH keeps the whole thing running. You interact with the Ethereum network by using ETH to pay the network to execute smart contracts. As a result, the fees paid in ETH are called “gas”.

Use cases

  • Decentralized finance (DeFi): An open and global financial system built for the internet age — an alternative to a system that’s opaque, tightly controlled, and held together by decades-old infrastructure and processes. It gives you control and visibility over your money. It gives you exposure to global markets and alternatives to your local currency or banking options. DeFi products open up financial services to anyone with an internet connection and they’re largely owned and maintained by their users. So far tens of billions of dollars worth of crypto has flowed through DeFi applications and it’s growing every day.
  • Non-fungible tokens (NFTs): Tokens that we can use to represent ownership of unique items. They let us tokenise things like art, collectibles, even real estate. They can only have one official owner at a time and they’re secured by the Ethereum blockchain — no one can modify the record of ownership or copy/paste a new NFT into existence. NFTs and Ethereum solve some of the problems that exist in the internet today. As everything becomes more digital, there’s a need to replicate the properties of physical items like scarcity, uniqueness, and proof of ownership. Not to mention that digital items often only work in the context of their product.
  • Decentralized autonomous organisations (DAOs): Think of them like an internet-native business that’s collectively owned and managed by its members. They have built-in treasuries that no one has the authority to access without the approval of the group. Decisions are governed by proposals and voting to ensure everyone in the organization has a voice. There’s no CEO who can authorize spending based on their own whims and no chance of a dodgy CFO manipulating the books. Everything is out in the open and the rules around spending are baked into the DAO via its code.

Advantages of Ethereum

Aside from decentralization and anonymity, Ethereum also has various other benefits, such as a lack of censorship. For example, if someone tweets something offensive, Twitter can choose to take it down and punish that user. However, on an Ethereum-based social media platform, that can only happen if the community votes to do it. That way, users with different viewpoints can discuss as they see fit, and the people can decide what should and shouldn’t be said.

Community requirements also prevent bad actors from taking over. Someone with ill intentions would need to control 51% of the network to make a change, which is nearly impossible in most cases. It’s much safer than a simple server that can be broken into.

It’s also getting easier than ever before to acquire Ether. Companies like PayPal and its Venmo subsidiary support purchasing crypto with fiat currency right within the application. Considering the millions of customers on each platform, they’re bound to get involved sooner rather than later.

Disadvantages of Ethereum

While it sounds like the perfect platform, Ethereum has a few key issues that need to be worked out.

The first is scalability. Buterin envisioned Ethereum the way the web is now, with millions of users interacting at once. Due to the PoW consensus algorithm, however, such interaction is limited by block validation times and gas fees. Furthermore, decentralization is a hindrance. A central entity, like Visa, manages everything and has perfected the transaction process.

Second, there is accessibility. As of the time of writing, Ethereum is expensive to develop on and challenging to interact with for users unfamiliar with its technology. Some platforms require specific wallets, which means that one must move ETH from their current wallet to the required wallet. That’s an unnecessary step for users ingrained in our current financial ecosystem and not beginner-friendly in the slightest.

Sure, PayPal is adding crypto support, but users can’t do much aside from holding it there. The platform needs to integrate with DeFi and DApps to increase accessibility in a meaningful way.

The platform does have some well-written documentation on the matter — another key way to bring in more users. But the act of actually using Ethereum needs streamlining. Learning about blockchain is very different from using it.

What is Bitcoin?

What is Bitcoin?

Bitcoin is a decentralized digital currency created in January 2009. It promises reduced transaction costs than standard online payment channels and, unlike government-issued currencies, is controlled by a decentralized authority.

Bitcoin employs peer-to-peer technology to function without a central authority or banks; the network manages transactions and issues bitcoins collectively.

Bitcoin is open-source, it means that its design is available to the public, no one owns or controls it, and everyone may participate.

In practice, bitcoin is a type of digital money that exists independently of any government, state, or financial institution, can be transmitted internationally without the need for a centralized intermediary, and has a known monetary policy that is arguably unchangeable.

There are no physical bitcoins; rather balances are recorded on a public ledger that everyone can see, although each record is encrypted.

A large amount of computational power is used to verify all bitcoin transactions, this process is known as mining. Bitcoin is neither issued or guaranteed by any banks or governments, nor is it worth anything as a commodity.

The bitcoin system is comprised on a network of computers (also known as nodes) that all execute bitcoin’s code and store its blockchain. A blockchain may be seen metaphorically as a collection of blocks, each block contains a set of transactions. No one can trick the system since all the machines running the blockchain have the same list of blocks and transactions and can observe these new blocks as they’re filled with fresh bitcoin transactions.

Bitcoin token balances are maintained using public and private “keys”, which are lengthy strings of numbers and characters connected by the mathematical encryption method that generates them.

The public key (like a bank account number) acts as the address that is made public and to which others may transfer bitcoin.

The private key (similar to an ATM PIN) is designed to be kept private and is only used to approve bitcoin transactions.

Bitcoin keys are not to be confused with a bitcoin wallet, which is a physical or digital device that facilitates bitcoin trade and allows users to track coin ownership. Because bitcoin is decentralized, it is never held “in” a wallet, but rather distributed on a blockchain.

Origin

Bitcoin is based on the ideas laid out in a 2008 whitepaper titled Bitcoin: A Peer-to-Peer Electronic Cash System.

The article described how to “allowing any two willing parties to deal directly with each other without the necessity for a trusted third party”.

The technology used solved the “double spend” problem, allowing for the first time in the digital world scarcity.

The bitcoin network’s initial growth was mostly driven by its usability as a revolutionary mechanism of exchanging value in the digital realm. Early supporters were mostly “cypherpunks”, or those who supported the employment of strong encryption and privacy-enhancing technology as a means of effecting social and political change.

However, speculation over bitcoin’s future worth quickly became a big motivator of adoption.

Mining

Mining is the process of releasing bitcoin into circulation. In general, entails solving computationally complex riddles to discover a new block, which is then added to the blockchain. Bitcoin mining adds and validates transaction records throughout the network.

Miners are rewarded with bitcoins, which is half every 210,000 blocks. In 2009, the block reward was set at 50 new bitcoins. On May 11, 2020, the third halving happened, reducing the reward for each block discovery to 6.25 bitcoins.

To mine bitcoin, a variety of hardware may be utilized. Some, however, provide greater benefits than others. Certain computer chips, known as application-specific integrated circuits (ASICs), as well as more complex processing units, such as graphic processing units (GPUs), can reap more benefits. These complex mining processors are referred to as “mining rigs.”

One bitcoin may be divided to eight decimal places (100 millionths of a bitcoin), and the lowest unit is known as a Satoshi.

How Many Bitcoins Are There?

The maximum amount of bitcoins that will ever be generated is 21 million, with the final bitcoin mined around the year 2140. More than 18.85 million (almost 90%) of the bitcoins had been mined as of November 2021. Furthermore, analysts believe that up to 20% of those bitcoins were “lost” as a result of someone forgetting their private key, dying without leaving access instructions, or transmitting bitcoins to invalid addresses.

Basic features

  • Decentralized: The bitcoin network is not controlled or owned by anyone, and there is no CEO. Instead, the network is made up of consenting individuals who follow the rules of a protocol (which takes the form of an open-source software client). Changes to the protocol must be approved by the protocol’s users, and there is a diverse range of contributing voices, including nodes, end users, developers, and adjacent industry participants such as exchanges, wallet providers, and custodians. As a result, Bitcoin is a quasi-political system.
  • Transparent: According to the protocol’s principles, the addition of new transactions to the blockchain record and the status of the Bitcoin network at any given moment is reached by agreement and in a transparent way.
  • Distributed: All Bitcoin transactions are recorded on a public ledger known as the “blockchain”. The network is based on volunteers keeping copies of the ledger and operating the bitcoin protocol software. These nodes help to ensure that transactions are correctly propagated over the network by adhering to the protocol rules as established by the software client.
  • Peer-to-peer (P2P): Although nodes maintain and disseminate the network’s state (the “truth”), payments are made directly from one person or organization to another. This eliminates the requirement for a “trusted third party” to operate as an intermediary.
  • Censorship resistant: Because all bitcoin transactions that adhere to the protocol’s rules are legitimate, transactions are pseudo-anonymous, and users own the ‘key’ to their bitcoin holdings, it is impossible for authorities to prohibit individuals from using it or take their assets. This has significant consequences for economic freedom and may potentially operate as a worldwide counterforce to dictatorship.
  • Permissionless: Anyone may use bitcoin; there are no gatekeepers, and no ‘Bitcoin account’ is required. The network will confirm all transactions that adhere to the protocol’s requirements using the established consensus procedures.
  • Fixed supply: One of the major characteristics is that the supply would gradually increase to a total of 21 million coins. This fixed and known total quantity, it is said, qualifies bitcoin as a ‘hard asset,’ one of numerous features that have led to its perceived value as an investment.
