These mechanisms are crucial for understanding how different cryptocurrencies function, so let me break them down in simple terms.

What is Proof of Work (PoW)?

Proof of Work is the original consensus algorithm used by many cryptocurrencies, with Bitcoin being the most famous example.

The concept is relatively straightforward: in a PoW system, participants, known as miners, compete to solve complex mathematical puzzles.

These puzzles are not trivial; they require substantial computational power to solve.

The first miner to crack the puzzle gets to add a new block of transactions to the blockchain.

The process of solving these puzzles and adding new blocks to the blockchain is called mining.

When a miner successfully adds a block, they are rewarded with newly created cryptocurrency, such as Bitcoin, along with transaction fees from the transactions included in the block.

This reward system incentivizes miners to participate in the network and maintain its security.

The difficulty of the puzzles is designed to be computationally intensive, making it extremely hard for any single entity to dominate the network.

This security feature ensures that an attacker would need more computing power than 50% of the network, making a successful attack highly impractical.

Check out this article on 51% attacks to get an idea of the costs of executing an attack.

What is Proof of Stake (PoS)?

Proof of Stake is a newer consensus algorithm that aims to address some of the inefficiencies and environmental concerns associated with Proof of Work.

In a PoS system, the process of validating transactions and creating new blocks is carried out by participants known as validators. To become a validator, one must hold and "stake" a certain amount of the cryptocurrency within the network.

The selection process for choosing who gets to create the next block is typically based on the amount of cryptocurrency a validator has staked, although other factors like the length of time the cryptocurrency has been held might also play a role.

Validators are rewarded with transaction fees and sometimes additional cryptocurrency for their efforts.

The staking process ensures that validators have a financial incentive to act honestly. If a validator attempts to act maliciously or validate fraudulent transactions, they risk losing some or all of their staked cryptocurrency.

This built-in penalty helps maintain the network's security and integrity.

Proof of Work vs Proof of Stake

Energy

When comparing PoW and PoS, several key differences emerge. One of the most significant differences is energy consumption. Proof of Work requires a tremendous amount of energy because of the intensive computational power needed for mining.

This high energy consumption has raised environmental concerns and calls for more sustainable alternatives.

Proof of Stake, on the other hand, is much more energy-efficient since it does not rely on solving complex puzzles.

Decentralization

Another important distinction is in terms of decentralization. Proof of Work is often viewed as more decentralized because anyone with the right hardware can participate in mining.

However, the cost of acquiring and running this hardware can be prohibitive for many people. Proof of Stake aims to be more accessible by lowering the barrier to entry; anyone who holds and stakes the cryptocurrency can potentially become a validator.

Nonetheless, PoS systems can sometimes favor those who already hold significant amounts of the cryptocurrency, which could lead to centralization.

Security

In terms of security, both PoW and PoS offer robust mechanisms but in different ways. PoW's security comes from the computational difficulty of mining, making it hard for any single entity to control the network. PoS relies on the financial incentives of staking; validators have a lot to lose if they act dishonestly, which encourages good behavior.

Conclusion

Both Proof of Work and Proof of Stake have their strengths and weaknesses.

Over the years, PoW has proven its security and reliability, especially with Bitcoin, but it comes with high energy costs. According to this article released in 2023, it's estimated that Bitcoin consumes around 160 terawatt-hours of electricity annually—more than the entire country of Argentina.

PoS, on the other hand, provides a more energy-efficient alternative but it must carefully manage the risks of centralization.

A governance token is one that allows holders of the token to have a say in the decision-making of a project.

They give holders voting power, similar to how shareholders can participate in the decision-making of a company based on the shares they have.

Imagine this: A crypto project, Storm DAO, launches, and you purchase their token, $SDO.

This grants you voting power, a voice in the way decisions are made in the project.

You can then use this voting power to contribute to decision-making, such as: should the transaction fee for $SDO holders be changed, should we donate 1% of revenue to a charity, or should we buy a Bored Ape with our treasury funds. You get the idea.

How does this work?

Well, a proposal is made by either the team or a community member. Voting takes place on the project's website and could run from either hours to days.

Once voting ends, the option that has the most votes is then picked and executed.

Why is this important?

It basically ensures that there is no centralized control. Decisions are not made based on what the team thinks is right and instead place power in the hands of the community, who, since they have their money invested in the project, are more likely to make decisions that favor them and the project.

An example of a governance project is Apecoin DAO—the DAO of the famous Bored Ape Yacht Club Token (ApeCoin).

Holders of the token were able to vote on whether a new blockchain (Apechain) should be created for ApeCoin. They subsequently voted on which entity they wanted to develop the chain. So instead of the team deciding, the whole community gets a say in how things should go.

This model too is not perfect because those who hold the majority of the project's tokens get more say, but it's still something, I guess.

Hopefully, improvements will be made to this model.

And that's it for this week, fam.

Coin burning is the destruction of a certain amount of cryptocurrency, essentially decreasing the total supply of the cryptocurrency, a process that is permanent and irreversible.

It's just like burning cash; once it's destroyed, it's gone forever.

Why are cryptocurrencies burned?

Essentially, you'd want to ask, why would anyone want to burn their cryptocurrency?

The truth is that there are actually a couple of valid reasons why coins or crypto tokens are burnt.

• To boost the price - Now, there's this general law of supply and demand, which you might know, that a decrease in the supply of a product will cause an increase in the price, provided the demand increases or remains constant.

So, theoretically, burning a coin, which essentially reduces the supply, should increase the price, provided that demand is the same or it increases. It should be noted that if the demand decreases, it might have a little effect on the price.

• Another purpose for coins to be burned is to build trust with the community.

Usually, when a developer or a team creates a coin, they allocate a certain portion of the coins to themselves. By burning their own supply, tht demonstrate to the community and demonstrate that they are that they are dedicated to the project and are not going to dump on them.

How does coin burning work?

Coin burning could be done in two ways:

1. By sending cryptocurrency to an address that has no private key. (In the crypto world, there are two types of keys: public and private keys. The next newsletter will delve into this topic further.)

What this means is that the tokens can no longer be used because the private keys to the coins are stored in an inaccessible wallet.

Or

2. Through a burn function - In this case, coin burning is executed through the burn function implemented in a chain's (Ethereum, Solana) smart contract.

When you intend to burn a coin, you specify the quantity you want to burn.

The smart contract then verifies your wallet to ensure you have enough coins. If you don't, the transaction is not executed. If you have sufficient coins, the function executes, and the specified coins are sent to the burn address, essentially removing them from the total supply.

Popular Token Burns

$PEPE

The developers of the Pepe memecoin (PEPE) burned 6.9 trillion ($5.5 million) of the token, which was followed by a 31% increase in price.

$SHIBA INU

In a marketing stunt, the developers of the Shiba Inu token sent Shiba tokens to Vitalik Buterin. Buterin donated 50 trillion SHIB to the India Covid Relief Fund and destroyed 90% of the total Shiba Inu sent to him, by sending 410 trillion of the meme-based coin to a dead wallet address. The amount of SHIB burned equates to over $6 billion.

But there are still many challenges they face, one of which is the lack of interoperability.

Interoperability refers to the ability of two different systems or blockchains to interact together seamlessly. This is something that blockchains are currently struggling with.

Think of it like going to a grocery store where you speak English, but the attendant speaks Mandarin. You really can't communicate or make any exchanges.

The same applies to different blockchains with varying functionalities and codes.

Wrapped tokens help solve this issue. They're tokens wrapped to function on another blockchain. For example, because Bitcoin and Ethereum aren't compatible due to their differences in standards and codes, to solve this BTC is wrapped into WBTC for use on the Ethereum blockchain.

How do you create one?

Creating a wrapped token involves three entities:

1. You, the user,

2. The token or funds to be wrapped, and

3. The custodian.

Here's how it works:

1. You send your funds to the custodian, which acts like a vault with codes and functions. It's responsible for turning your token into its wrapped version.

2. You send your token to the custodian. It then creates a wrapped version of your token and locks away the original in a vault. Meanwhile, it sends the wrapped token to your wallet.

3. You can now use the wrapped token for whatever you need. If you decide you don't want it anymore, you send it back to the custodian.

4. The custodian then destroys (burns) the wrapped token and gives you back the original token from the vault.

What are the advantages of wrapped tokens?

One of the advantages is enhanced functionality. Let me break this down: gas fees on Bitcoin can be pretty high at times. Recently, data shows that they rose up to $80 this week.

Imagine if you were to make a transaction of $20, you'd be paying gas of $80 (check this out if you don't know the meaning of gas).

So, if you wrap your Bitcoin to Ethereum or Polygon, you can essentially bypass the gas fees that have been paid on the Bitcoin network and leverage the lower transaction fees of the network.

Another perk of wrapped tokens is the access they provide to decentralized applications (dApps) and lending platforms.

Before wrapped tokens came into play, Bitcoin users couldn't access Ethereum's features like lending, borrowing, or tokenization due to their differences in codes and functionalities. But now, with wrapped tokens, they can tap into these features by converting to wBTC.

What are the disadvantages of wrapped tokens?

One of the drawbacks is the reliance on the custodian. If you look at the whole process of wrapping the token, the custodian plays a significant role in both wrapping the token and custody, and this contradicts the whole idea of decentralization in blockchain, where you ought to have control over your funds and activities.

With that being said, the advantages outweigh the disadvantages and in the long run, we're bound to see more upgrades to Blockchain networks that deal with the issue of interoperability.

What's meant by it being distributed?

It means that the data on the blockchain and the tasks of maintaining it are not done by a single entity but rather by a network of computers located in various locations, spanning countries.

By doing this, each computer in the network stores a copy of the blockchain where transactions are recorded to prevent a single point of failure. Additionally, all copies are updated simultaneously.

What's meant by it being public?

It means that the information on it can be accessed and viewed by anyone who wants to check it.

Now that that's out of the way, let's move on.

As the name suggests, blocks in a blockchain are linked and consist of three fundamental elements:

1. The data being stored in it - For example, information about a transaction, the sender, the receiver, the amount transferred, and the time.

2. The hash of the block - likened to the digital fingerprint of the block.

3. The hash of the previous block - included in the block, linking them together in chronological order, similar to page numbers in a book.

An exception to this is the genesis block, which is the very first block in a blockchain.

How does it work?

You can liken a blockchain to a spreadsheet (although it's more complex than that). Information is collected and entered into a block (similar to how information is entered into a cell in a spreadsheet). Once the block is full, its hash is calculated by a special mathematical function. This function calculates the data of the block to generate a unique fixed-length string of characters (the hash).

The block is then validated (checked for errors or tampering) by a consensus mechanism (read more about them here) and added to the blockchain. After it has been added and recorded, it becomes nearly impossible to alter it.

This process repeats for subsequent blocks.

Benefits of the Blockchain

• Transparency:

Blockchain, likened to a public ledger, ensures that every participant has a clear view of the recorded data. This real-time visibility minimizes the risk of fraudulent activities, as any alterations are promptly evident to all involved parties.

• Immutability:

Once info is in the blockchain, it's almost unchangeable, like engraving in stone. This builds trust in the stored data.

• Traceability:

The blockchain acts as an advanced tracking system, crucial for identifying and resolving issues, especially in supply chain management.

• Decentralization:

Unlike centralized control, blockchain spreads power across the network, avoiding a single point of failure and creating a more resilient system.

Some Big Tech Company services are dependent on centralized servers; any downtime or issues with these servers can affect the availability of all their services. In contrast, blockchain technology operates on a decentralized network spread across various nodes. This decentralized structure minimizes the risk of a single point of failure, ensuring that even if one node experiences downtime, the overall blockchain network can continue functioning.

Limitations of the Blockchain

• Scalability:

Blockchain faces challenges in scalability, meaning its ability to handle a large volume of transactions efficiently. As more users join the network, transaction speeds may decrease, and fees can rise. This limitation hinders the widespread adoption of blockchain for high-frequency transactions.

• Energy Consumption:

Some blockchain networks, especially those like Bitcoin, need a lot of energy for transaction validation, raising environmental concerns.

• Interoperability:

Different blockchain networks operate independently, limiting smooth communication between them. This means assets or data can't flow seamlessly across different blockchains.

• Security Challenges:

Despite its security reputation, blockchain ecosystems aren't immune to vulnerabilities. Smart contracts, 51% attacks, and other exploits pose risks needing ongoing attention.

So that explains the blockchain.

Vocab of the Day

• Consensus Mechanism: The process by which nodes on a blockchain agree on a single version of the truth or validate transactions. Examples include Proof of Work (PoW) and Proof of Stake (PoS)

• Immutable: Once data is added to the blockchain, it is almost impossible to change or tamper with. It's like an unalterable record.

• Node: A computer that participates in the blockchain network, verifying and validating transactions.
