Ethereum: Unpacking the Secret of Bitcoin’s Inflation Resistance

For months, the debate over Bitcoin’s (BTC) immunity to inflation has been a topic of discussion among cryptocurrency enthusiasts and investors alike. While some argue that Bitcoin is impervious to price fluctuations due to its scarcity and limited supply, others argue that this narrative is oversimplified or even misleading. In this article, we’ll delve deeper into the concept of inflation and how it applies to both Bitcoin and other cryptocurrencies like Ethereum (ETH).

Understanding Inflation

In economics, inflation refers to a sustained increase in the general price level of goods and services over time. It is characterized by an uneven distribution of wealth, with some individuals or groups benefiting disproportionately from increased prices while others bear the brunt. The primary driver of inflation is usually demand-pull factors, such as a growing economy or an increase in aggregate demand.

The Problem with Bitcoin Inflation

So, can bitcoins truly be immune to inflation? The answer lies in their design and underlying economics. Here are some key points to consider:

• Limited Supply: The total supply of bitcoins is limited to 21 million, meaning that as more people join the market, the number of new bitcoins increases. This limited supply, combined with the relatively small market capitalization, reduces the likelihood that prices will skyrocket.

• Mining and Transaction Fees

  : The process of validating transactions on the blockchain and minting new bitcoins requires significant computing power and energy expenditure. As more miners join the network, mining costs increase, which can lead to reduced profitability and higher fees.

• Centralized Exchange (CEX) Dominance: Many CEXs are controlled by institutional investors or large financial institutions, who often own significant portions of the Bitcoin reserves. These centralized entities can manipulate prices, leading to an artificially inflated market.

Ethereum: A Different Story

While it is true that Ethereum (ETH) also faces supply concerns and potential price volatility, its underlying economics are significantly different from Bitcoin’s. Here are some key points to consider:

• Scalability: Ethereum’s design allows for a wide range of decentralized applications (dApps) to be created, which increases demand on the network and subsequently drives up prices.

• Tokenization: The ability to create, trade, and mint new tokens on the Ethereum platform creates a huge supply of ETH, making it less susceptible to price inflation.

• Interoperability: Ethereum’s open-source architecture enables seamless interaction between different applications and networks, fostering a stable ecosystem that encourages adoption and reduces the risk of market volatility.

Inflation resistance: A myth?

The notion that bitcoin is immune to inflation is a misconception. While it is true that some aspects of bitcoin’s design can limit its price volatility, the overall narrative of its inflation resistance is flawed. The combination of limited supply, rising transaction fees, and centralized dominance on CEX can contribute to an artificially inflated market.

In conclusion, the notion of “inflation-resistant” cryptocurrencies like bitcoin and Ethereum is an oversimplification. Both platforms face unique challenges that impact their ability to maintain price stability. By understanding the underlying economics and complexities of each asset, we can better appreciate the complexity of the cryptocurrency market and avoid making unfounded claims about its price behavior.

Verifying Wallet Ownership Without Providing the Private Key

In today’s digital age, cryptocurrency transactions are becoming increasingly complex, and verifying the ownership of a wallet can be a daunting task. One question that has sparked curiosity among security enthusiasts and experts alike is, “Is it possible to verify that a wallet belongs to its owner without revealing the private key?” The answer is not a simple yes or no, but requires a nuanced study of cryptographic techniques.

What Makes a Wallet Secure?

The security of a wallet depends on its ability to be encrypted and protected from unauthorized access. One aspect of this is the use of passwords, PINs, or other authentication mechanisms that prevent others from accessing the private keys associated with a wallet. However, these measures are not foolproof, as an attacker could guess the password or crack it using brute force methods.

Private Key Management

To verify ownership without revealing the private key, we need to delve into the world of private key management. A private key is a unique string of characters that serves as a digital signature for every transaction on a blockchain network. It is essentially a cryptographic fingerprint that reveals transactions and allows for secure verification.

There are several techniques to effectively manage private keys:

• Hardware Wallets

  : Hardware wallets like Trezor or Ledger store the private key offline, making it virtually impossible for an attacker to access it without the physical device.

• Seed Phrases: Some wallets use seed phrases, which are a series of words that serve as a backup in case the hardware is lost or damaged. These phrases are used to restore the wallet and recover ownership.

• Paper Wallets: Paper wallets provide a secure way to store private keys on paper by using QR codes or other formats to link the wallet to the corresponding seed phrase.

Verify Ownership Without a Private Key

While it is theoretically possible to verify ownership of a wallet by examining the blockchain history or identifying patterns related to account behavior, these methods have inherent limitations:

• Blockchain History: Examining the blockchain may reveal activity on the account that does not necessarily indicate the owner is the original holder.

• Behavioral Patterns: Analyzing transaction patterns can identify suspicious activity, but without additional context, the identity of the owner cannot be guaranteed.

Brute Force Attacks

Unfortunately, brute force attacks remain a serious threat to wallet security. An attacker could attempt to guess or crack the private key using special software or services. This type of attack typically requires significant computing power and can be executed with minimal effort.

Conclusion

Verifying ownership of a wallet without providing the private key remains an elusive goal in today’s digital landscape. While some wallets, such as those from established organizations (e.g. Ethereum), offer more robust security features, these solutions are not foolproof.

How to minimize risks and ensure the integrity of your cryptocurrency holdings:

• Use a trusted wallet provider

  

  : Choose an established wallet that prioritizes security and follows best practices for private key management.

• Keep your wallet offline: Hardware wallets or paper wallets can protect against unauthorized access.

• Be careful with seed phrases: Make sure you know how to recover ownership in the event of hardware loss or damage.

While it is important to be cautious when dealing with cryptocurrencies, using secure practices and tools can significantly reduce the risk of your wallet being compromised.

«Cryptocurrency Market Insights: The Role of Order Flow and On-Chain Technologies in the Age of Centralization»

As the world’s largest cryptocurrency market continues to evolve, it is essential for investors, traders, and industry observers to understand the dynamics that are driving it. Two key elements of this ecosystem are order flow and on-chain technologies, which play a critical role in shaping the cryptocurrency market.

Order Flow: The Lifeblood of Markets

Order flow refers to the speed and efficiency with which orders are executed in cryptocurrency markets. It is measured by the number of transactions executed per second (TPS) on exchanges such as Binance, Coinbase, or Kraken. Healthy order flow indicates that buyers and sellers are actively participating in the market, facilitating liquidity and maintaining price stability.

Order flow has been a key factor in driving price movements, especially during times of high market volatility. When order flow is strong, it attracts more investors to the market, increasing demand for assets and driving up prices. Conversely, low order flow can lead to congestion, lower trading volumes, and reduced market liquidity.

The recent surge in cryptocurrency prices has been attributed, in part, to increased order flow on platforms such as Binance. As the global economy continues to recover from the pandemic, investors are seeking safe-haven assets like cryptocurrencies, driving up demand for these assets.

Centralization: A Growing Concern

Centralization refers to the concentration of market capitalization among a few major players, typically those with high liquidity and trading volumes. This can lead to increased market volatility and decreased liquidity as smaller players struggle to compete for market share.

The cryptocurrency market has seen significant centralization over the years, with assets such as Bitcoin and Ethereum dominating the market share. As more investors become more familiar with the risks associated with centralization, there is growing concern about its implications for market stability.

Blockchain Technologies: The Building Blocks of the Future

Blockchain technologies, including proof-of-stake (PoS), decentralized finance (DeFi), and non-fungible token (NFT) protocols, are revolutionizing the way we think about cryptocurrencies. These emerging technologies enable more efficient, decentralized, and user-friendly interactions within the crypto ecosystem.

Multichain: A New Era of Interoperability

The term multichain refers to the concept of interoperability between different blockchain networks, enabling seamless asset transfers between platforms. This has important implications for traders and investors looking to diversify their portfolios or access new opportunities.

The emergence of multichain technologies such as Polkadot, Solana, and Cosmos is transforming the way we think about cryptocurrency integration. As these protocols enable more efficient data transfer and interaction between different blockchain networks, they open up new possibilities for decentralized applications (dApps) and use cases.

Conclusion

Order flow and blockchain technologies play a critical role in defining the dynamics of the cryptocurrency market. Understanding how to navigate these markets requires a deep understanding of the technical aspects of cryptocurrency trading and the broader ecosystem.

As the cryptocurrency market continues to evolve, it is essential to stay informed about the latest developments in centralization, order flow, blockchain technologies, and multi-chain protocols. By doing so, we can better navigate this complex landscape and capitalize on emerging opportunities.

Abnormally closed.

When working with the Binance REST API using WinHTTP, you may encounter a situation where the request fails due to an abnormal connection termination with the server. This error code 12030 usually indicates that the server unexpectedly closed the connection. In this article, we will look at how to force close a connection when receiving such an error.

Understanding Binance REST API Connection

Before diving into the solution to force close a connection, it is necessary to understand how Binance REST API handles connections with WinHTTP. When using WinHTTP as a proxy or in the context of an application, you may need to establish multiple connections to handle different scenarios at the same time. These connections can become clogged after use if not managed properly.

Solution: Force Close the Connection

To force close the connection when you encounter error code 12030, follow these steps:

1. Establish connections and receive information

First, make sure that there are no errors when establishing the connection. If everything goes well, you may want to save or print information about each connection made for analysis purposes.

import requests





Define the API endpoint URL and parameters
url = "

Initialize the dictionary with connection information
connect_details = {
'method': 'GET',
'params': [1, 2, 3], 
Change these values ​​if necessary
}
response = requests.get(url, params=connection_details)
if response.status_code == 200:
print("Connection successful.")
else:
print(f"Failed to establish connection: {response.text}")

2. Close the connection

If an error occurs during the development process and the solution is not immediately obvious, consider closing the connections. This step is crucial to maintaining performance and reducing resource usage.

import axis

Get a list of currently open connections
open_connections = []
i in range (1, 21): 
Replace with a real number or boolean to close all but the specified number
try:
conn_details = {
'method': 'GET',
'params': [i], 
Change values ​​as needed
}
response = requests.get(url + str(i), params=conn_details)
if response.status_code == 200:
print(f"Connection established {i}.")
open_connections.append(conn_details['url'])
except exception like e:

Log the error and continue with another connection
print(f"Failed to establish connection {i}: {str(e)}")

Close the specified number of connections (in this case 18)
url in open_connections[:len(open_connections) - len([conn['url'] for conn in open_connections]) // 2]:
os.system("taskkill /im " + url)
print(f"Connections closed. Remaining: {len(open_connections)}")

Conclusion

Forcing a connection to close is a last resort measure that should be used judiciously to reduce unnecessary resource usage and maintain application performance. Always log errors for troubleshooting purposes to understand the cause of problems encountered when establishing or closing a connection.

Disclaimer: Before implementing this solution in production environments, ensure that your system can handle temporary process termination (e.g. by using Windows Task Manager). Also, be careful when using this method as it may have unintended consequences for your application’s performance.

Ethereum: understanding the gap limit and how it affects your wallet

As an Ethereum user, you are probably aware of the growing demand for Bitcoin (BTC) payments. One of the significant problems is the gap limit in your wallet, which can cause an unexpected outflow of funds when the limit is exceeded. In this article, we’ll look at what the gap limit means for your Ethereum wallet and how to mitigate potential losses.

What is a gap limit?

In Ethereum wallets, the gap limit refers to the maximum amount that can be stored in a single transaction or wallet without exceeding the wallet balance. This limit prevents users from withdrawing funds before they become available. Think of it as a buffer zone that ensures your wallet has enough funds for each transaction.

How ​​does the withdrawal limit affect my wallet?

When you ask to withdraw funds from your wallet in excess of its gap limit, the exchange rate will be unfavorable. For example:

• If your breakout limit is 1 Ether (ETH) and you want to withdraw 2 ETH, your wallet may only have enough balance to process one transaction, leaving you with 0 ETH.

• The next withdrawal request will require you to wait for the resolution of the previous transaction, which may take some time. During this interval, new funds are not added or withdrawn.

Break limit: Is it a problem?

While the concern about the gap limit is understandable, it is relatively easy to manage. If your wallet is configured correctly and you know about the limits, you will be able to withdraw funds without problems. However, if you are not careful, there are potential risks:

• Unplanned withdrawals: You can make a mistake, forget to set a withdrawal limit or miss warnings about excessive spending.

• Market Fluctuations: If ETH prices suddenly drop, your wallet balance may become unfavorable.

How ​​to mitigate potential losses

To minimize the risk of losing funds due to the gap limit:

• Set a gap limit

  

  : Set up your wallet with a suitable gap limit, taking into account your trading activity and budget.

• Monitor Your Balance: Check your wallet balance regularly to make sure it doesn’t exceed your withdrawal limit.

• Use Smart Contracts: Consider using smart contract wallets that offer more flexible features and better risk management.

• Diversify Your Assets

  : Spread your funds across different cryptocurrencies, including Ethereum, to reduce exposure to any single asset.

Conclusion

Break limit is a built-in security feature in Ethereum wallets designed to prevent unexpected withdrawals. While it’s important to understand the implications, you can take steps to mitigate potential risks by setting an appropriate gap limit and remaining vigilant about your wallet balance. By doing so, you will be better prepared to manage your assets and take advantage of the benefits of using bitcoins for payments.

Ethereum transaction IDs (txIds) are used to identify each unique transaction that occurs on the Ethereum network. However, finding duplicate txIds is a complex problem due to several factors:

• Transaction ID generation: Genesis Block is the starting point of the Ethereum blockchain, and its txId is fixed. All subsequent transactions will have a different txId from their analog source. This means that every transaction on the network has a unique txId.

• Mutated Transactions: Mutated transactions are those that have been changed from their original state during processing or validation. These changes may affect the txId, but do not guarantee duplicates. However, mutated transactions often involve changes to data such as fuel costs and block numbers.

To detect duplicate txIds, we need to analyze both the genesis blocks and subsequent transactions. Here are some steps you can take:

Step 1: Analyze the Genesis Blocks

• Find the genesis block

  

  : Get a copy of the genesis block of the Ethereum blockchain.

• Check for duplicate txIds: Use libraries or APIs provided by the Ethereum project or external services like Chainlink to query all transactions on the network. Compare each transaction’s txId with the genesis txId.

Step 2: Analyze subsequent transactions

• Find match with previous block number: Check if transactions in subsequent blocks have a matching txId from the block before it.

• Use a hash table or similar data structure: Store the txId of each transaction and the corresponding block number. When comparing, use the block number as the primary key.

Step 3: Mutated transactions

• Analyze transactions for changes: Review all transactions and look for any signs of mutations (eg increased fuel costs or processed blocks).

• Identify Potential Duplicates

  : Based on your findings from steps 1 and 2, identify which transactions may have been affected by the mutations.

Example code

Below is an example of how you can use the `ethers.js’ library to query all transactions on the Ethereum network and detect duplicate txIds:

const ethers = require('ethers');


// Function to query all transactions on the Ethereum network

asynchronous function getTransactions() {

  const provider = new ethers.providers.JsonRpcProvider("

  const accounts = await provider.getAccounts();

  const txIds = [];


  for (const account account) {

    try {

      const blockNumber = await provider.getBlockNumber(account.address);

      const txs = await provider.getTransactionLogs(account.address, "latest", null);


      for (const tx of txs) {

        if (txIds.length === 0 || txIds[txIds.length - 1] !== tx.id) {

          txIds.push(tx.id);

        }

      }


      // Optional: Mutated transactions

      const mutatedTx = await provider.getTransactionLog(account.address, "latest", null);

      if (mutatedTx.gasCost > txs[0].gasCost || mutatedTx.blockNumber < txs[0].blockNumber) {

        txIds.push(mutatedTx.id);

      }

    } catch (error) {

      // Handle errors as needed

    }

  }


  return txIds;

}


// Usage example:

asynchronous function main() {

  const txIds = await getTransactions();

  console.log("Duplicate txIds:", txIds);


  // Optional: Mutated transactions

  const mutatedTxId = await getMutatedTransaction(txIds);

  if (mutatedTxId) {

    console.log("Found mutated transaction:", mutatedTxId);

  }


  return null;

}


main().catch((error) => {

  console.error(error);

});

This code snippet shows how to query all transactions on the Ethereum network and detect duplicate txIds. However, please note that this is just an example and you may need to adjust it based on your project requirements.

Does Your Bitcoin Multiply With Every Fork?

The Ethereum blockchain is built on a decentralized, open-source technology called Proof of Work (PoW), which requires significant computing power to validate transactions. However, it’s not the only cryptocurrency that uses this consensus mechanism. Other cryptocurrencies like Bitcoin Cash (BCH) and Bitcoin NANO (BTNC) also use PoW.

When you buy or sell Bitcoin, your funds are transferred from one address to another. But what happens when a new fork occurs on the Ethereum blockchain? Can your existing Bitcoin multiply with every fork?

To understand this question, let’s dive into the basics of cryptocurrency and blockchain technology.

How ​​Cryptocurrencies Work

Cryptocurrencies like Bitcoin and Ethereum use cryptography to secure transactions and control the creation of new units. Each block on a blockchain contains a “transaction,” or set of transactions that are confirmed through complex mathematical calculations (known as proof of work). The first transaction of each block is rewarded with newly minted coins.

Forks: What are they?

A fork occurs when a group of developers creates a new version of the blockchain that differs from the original code. This creates a new version of the cryptocurrency, often referred to as a “fork.” For example, if you have 100 Bitcoins and decide to switch to Ethereum, your funds will not be transferred automatically. You will need to convert your Bitcoin to Ether (ETH), which is the native cryptocurrency of the Ethereum network.

Does Your Existing Bitcoin Multiply with Each Fork?

Now let’s consider whether your existing Bitcoin will increase with each fork of the Ethereum blockchain. The answer is no, unfortunately.

Here’s why:

• Cryptographic Complexity: Each new block on the Ethereum blockchain requires significant computing power to validate transactions. This makes it difficult for users to “mine” or “hack” their way to accumulating large amounts of Bitcoin.

• Limitations of Smart Contracts

  : Smart contracts are self-executing contracts with specific terms and conditions. They can be used to transfer ownership, create new assets, and perform other blockchain operations. However, smart contracts do not automatically increase in value or size with each fork.

• Supply and Demand Dynamics: The number of Bitcoins mined per block is limited by the level of complexity required to solve the mathematical puzzle (Proof of Work). This means that even if there are new forks, your holdings are unlikely to increase exponentially.

Exceptions: Special Cases

While your existing Bitcoin may not multiply with each fork of the Ethereum blockchain, there are a few exceptions:

• Bull Market Trends: If you bought Bitcoin at a low price and then sold it at a higher price due to high demand, you may see a large price increase.

• Initial Coin Offerings (ICOs): When new cryptocurrencies, such as ERC-20 tokens or BEP-20 tokens, are issued, their total supply is often determined by the developers themselves. In these cases, your holdings can increase as more coins become available.

Conclusion

While Bitcoin can increase in value with each fork of the Ethereum blockchain, it does not follow a simple multiplicative model. Instead, factors such as supply and demand dynamics, smart contract limitations, and market trends play a major role in shaping cryptocurrency prices.

As a result, your Bitcoin holdings will not increase exponentially with each fork. However, if you invest in the right cryptocurrencies at the right time, you can experience significant growth opportunities due to market uptrends or other market factors.

Ethereum: The Rise of Self-Assembling Hardware for Bitcoin Mining

In recent years, demand for high-performance computing hardware has exploded, driven by the growing popularity and use cases of cryptocurrencies like Bitcoin. As a result, the need for specialized hardware designed for Bitcoin mining has increased. An innovative approach to address this challenge is to develop self-assembling devices that can be easily customized and upgraded without extensive technical expertise.

What is self-assembling hardware?

Self-assembling hardware refers to systems that can manufacture their own components, such as microprocessors, memory chips, or even entire boards, using a combination of 3D printing, laser cutting, and other advanced manufacturing techniques. This approach allows for the creation of customized hardware with features tailored to the user’s needs.

Ethereum ASIC Mining Algorithm

The Ethereum platform has introduced a new mining algorithm that takes advantage of the self-assembly capabilities of the hardware. The Ethereum Virtual Machine (EVM) is a critical component of the Ethereum network, and its ability to perform complex calculations requires high-performance computing resources. To meet this need, the team behind Ethereum has developed a custom ASIC miner for Bitcoin mining.

EVM-ASIC Miner

The EVM-ASIC mining machine uses advanced 3D printing techniques to create the necessary components, such as transistors, resistors, and capacitors, which are then assembled into a compact module. This module is capable of performing complex calculations at very high speeds, making it an ideal solution for Bitcoin mining.

Available Guides and Hardware

While there aren’t a ton of official guides or documents specifically designed for building Ethereum ASIC miners, several resources have emerged that offer valuable information and guidance:

• Official Ethereum Documentation: The Ethereum team has published documentation on their website that details the design and implementation of EVM-ASIC mining.

• Bitcoin Mining Guides: Several online forums and communities, such as Reddit’s r/WeAreTheMultiverse, have shared resources and tutorials for building Bitcoin mining hardware using self-assembly techniques.

• 3D Printing and Laser Cutting Tutorials: YouTube channels like “Tinkercad” and “Instructables” offer step-by-step instructions for 3D printing and laser cutting custom components for your own EVM-ASIC miners.

Challenges and Limitations

While the idea of ​​self-assembling hardware for bitcoin mining is promising, there are several challenges and limitations to consider:

• Regulatory Framework: The development and production of self-assembling hardware may be subject to regulatory oversight in some jurisdictions.

• Scalability

  : As demand for Ethereum ASIC miners increases, manufacturers must increase production while maintaining quality control.

• Component Availability: Limited availability of certain components, such as high-quality transistors or special resistors, may hamper the development and production of EVM-ASIC mining equipment.

Conclusion

The emergence of self-assembling hardware for bitcoin mining presents an exciting opportunity for innovation and decentralization in the cryptocurrency space. Although documentation and resources are currently limited, several online communities and forums offer valuable information on building Ethereum ASIC miners using 3D printing and laser cutting techniques.

As the demand for high-performance computing hardware increases, the need for specialized equipment designed for bitcoin mining becomes increasingly important.
