Blockchain

Blockchain is the technology behind Bitcoin and other cryptocurrencies. I don’t know much about it yet, but I have purchased some research material and will be investigating it and writing at least one article about it.

When I read stories about people getting banned from using PayPal and other banking services because of their political opinions, I think we need to start looking for some kind of alternative trading system. One that protects our privacy, our freedom of conscience and our free enterprise.

I’m not sure if cryptocurrency is the best solution. It’s just worth taking a look at it. On one hand, I am a big advocate for free and open source software. On the other hand, I’m a big fan of privacy, private property and free enterprise.

I like free and open source technology, because I don’t want any corporation owning or controlling my technology. I don’t want to be controlled by the government or by any private or public corporation, including the Free Software Foundation.

Freedom is lawful, not lawless. I am not an anarchist. The rule of law is the antidote to the rule of man. We can build machines that fly by discovering the laws of aerodynamics and following them. We can produce prosperity by learning the natural laws of economics and practicing them.

The United Nations’ Sustainable Development Goal, number 17, calls on corporations to work directly with the United Nations to bring good ethical economics into every society on earth. I’m all for that, however, it seems like that good idea is being corrupted into promoting an authoritarian ruling class.

The rule of law should be liberating the people of earth, not entangling us in any culture of dependence or corrupt imperial pyramid. National socialism is private ownership of the means of production, controlled by the state. That is not what we need our world government to be doing.

We need our world government to serve and protect the people of earth from any tyrants. No bullies allowed, anywhere on earth. Free and open source software, free and open source education and free and open source healthcare are major facets of the solution to the control freaks, bureaucrats and self appointed ruling class.

Blockchain technology may be a significant aspect of the remedy for the tendency of some people to want to control the people around them. Society has a right to defend itself. We need laws and institutions to defend against any and all tyrants, whether they are street criminals, drug pushers, human traffickers, selfish business executives or corrupt government bureaucrats.

Blockchain technology, along with a virtual private network and perhaps a Tor browser may be tools we can use to protect our privacy. We’ll see how blockchain technology fits into the holistic perspective of computer science and artificial intelligence.

The war is over. That military industrial complex we built to win World War 2 has become exactly what we built it to defeat, a totalitarian state controlling every detail of our economy. We have got to fix that. We can fix that. Blockchain technology and free and open source software will help us break free from the self appointed ruling class of tyrants. Freedom, equality and justice for all people everywhere are good ideas.

I am not advocating for any kind of corruption either. The divine education revealed by Baha’u’llah, the Baha’i Faith, is the divine guidance that is absolutely essential for any form of private enterprise and free and open source culture to thrive.

Man made rules are inherently corrupt. That includes people making the rules in their own lives or anyone else’s life. Voluntary submission to God is the inner essence of every true religion. God makes the rules.

Blockchain can help us transform the banking and trading process into a more secure, reliable, efficient, transparent and flexible system. It can enable faster and cheaper transactions, reduce fraud and dependence on intermediaries, and improve customer experience.

Using Blockchain in Your Home Office

Blockchain is not only a technology for cryptocurrencies and finance. It can also be a useful tool for your home office, especially if you work remotely or collaborate with others online. Along with AI, Blockchain can help you improve your productivity, security, privacy and trust in your home office.

Use blockchain-based apps and platforms. There are many blockchain-based applications and platforms that can help you with various tasks and projects in your home office. For example, you can use Evernote Chain to store and sync your notes on a decentralized network, or Provenance to track and verify the origin and quality of the products you buy or sell online. You can also use Steemit to create and share content on a blockchain-based social media platform, or Brave to browse the web faster and more privately with a blockchain-based browser.

I’ve been using Brave as my default browser. Brave is a blockchain-based browser. I’ll have to drill down and find out what that means. I knew it was secure and privacy oriented. I did not know it was based on blockchain.

I was having a problem updating and upgrading my computer and I decided to change from KDE Neon to Pop!_OS. I found out that Brave was causing the problem all along and made it very difficult to change the operating system. That is not necessarily a bad thing. You just have to learn how to configure it properly. In the mean time, I’ve switched back to Firefox.

Use blockchain-based identity and authentication. Blockchain can help you protect your identity and authenticate yourself online without relying on third-party services or intermediaries. For example, you can use Civic to create and manage your digital identity on a blockchain, or uPort to access various websites and apps with your blockchain-based credentials. You can also use Blockstack to build and use decentralized apps that respect your privacy and data ownership.

Use blockchain-based payments and transfers. Blockchain can help you send and receive money or other assets faster, cheaper and more securely than traditional methods. For example, you can use Bitcoin, Ethereum or other cryptocurrencies to pay or get paid for your work or services online or use Abra to exchange and transfer money across different currencies and platforms. You can also use Bitwage to receive your salary in Bitcoin or use Request Network to create and manage invoices on a blockchain.

Blockchain can help you collaborate and communicate with your colleagues, clients or partners online in a more transparent, efficient and trustworthy way. For example, you can use Colony to create and manage decentralized organizations and projects on a blockchain or use OpenBazaar to buy and sell goods and services on a peer-to-peer marketplace. You can also use Status to chat and share files on a blockchain-based messaging app or use Decent to publish and distribute content on a blockchain-based platform.

Protect your privacy and your private property with blockchain-based technology and crypto-currency and a secure VPN and the Brave browser and search engine.

Understanding Blockchain Technology

Blockchain is a revolutionary technology that has transformed how we think about data storage, security and transactions. While it is most commonly associated with cryptocurrencies like Bitcoin, its applications extend far beyond digital currency.

Blockchain is a distributed ledger technology (DLT) that records transactions across a network of computers in a secure, transparent and tamper-proof manner. The “blockchain” gets its name from the way it stores data—in blocks that are linked together (chained) in chronological order.

No single entity controls the blockchain. Instead, it operates on a peer-to-peer network. Blockchain transactions are immutable. Once a transaction is recorded in the blockchain, it cannot be altered or deleted. Blockchain technology is transparent. All participants can view the ledger, promoting trust and accountability. Cryptographic algorithms ensure that the data is secure from unauthorized access or tampering.

How Blockchain Works

I still don’t quite understand the value that solving math problems adds to the economy. Unless the math problems are actually solving some problem, like predicting actual space ship trajectories or something like that. Gold has intrinsic value. Government back currency is based on the productivity of the people of the nation. That is valuable. Exactly how is solving math problems valuable.

The process of solving math problems in Bitcoin mining is critical to the functioning and security of the Bitcoin network. This seemingly abstract activity underpins the trust, decentralization and value of Bitcoin as a digital currency.

The math problems miners solve are part of a process called Proof of Work (PoW). These problems are designed to be computationally intensive but easy to verify. Their solution prevents fraud and double spending. Bitcoin mining ensures that each Bitcoin transaction is unique and irreversible. Without solving these math problems, malicious actors could attempt to spend the same Bitcoin multiple times (double spending).

Blockchain technology creates consensus without a central authority. Bitcoin operates on a decentralized network, meaning no single entity controls it. The math problems serve as a way for all participants (miners) to agree on the validity of transactions. This builds trust among users.

When a miner solves a math problem, they add a block of transactions to the blockchain. This block contains transaction data, details about Bitcoin transfers. A hash is a unique identifier for the block. A previous block hash links the current block to the previous one, ensuring the chain’s integrity.

The math problem is designed such that finding the correct solution (or hash) is computationally difficult. This protects against tampering. Changing any transaction in a block would require solving the math problem again for that block and all subsequent blocks—a computationally impossible task for any single entity.

Mining creates value through Bitcoin Rewards. Miners who solve the math problem first are rewarded with newly minted Bitcoins. This reward incentivizes miners to contribute computational power to secure the network. Miners also earn fees paid by users to prioritize their transactions. As Bitcoin rewards decrease over time (due to halving events), transaction fees will become a primary incentive.

Mining is the process by which new Bitcoins enter circulation. Solving math problems limits the rate at which new Bitcoins are created. The Bitcoin protocol caps the total supply at 21 million. Mining math problems ensures a steady and predictable release of new coins, avoiding inflationary pressures.

Why Math Problems Specifically?

The math problems in Bitcoin mining are based on cryptographic algorithms (SHA-256 for Bitcoin). The problems serve several purposes. The network adjusts the problem’s difficulty roughly every two weeks to maintain a consistent block production rate (about one block every 10 minutes). Solving these problems requires computational effort but no special knowledge. This ensures fairness, as anyone with enough computational power can participate.

Mining Bitcoin and solving its math problems contribute to decentralization by distributing mining across a global network, no single entity can control Bitcoin. This prevents monopolies and censorship.

Blockchain uses trustless transactions. Bitcoin eliminates the need for intermediaries (e.g., banks) by enabling peer-to-peer transactions secured by miners. Bitcoin mining has spawned industries, including hardware manufacturing, renewable energy solutions and financial services.

Despite its value, Bitcoin mining and solving math problems face challenges. Mining is energy-intensive, leading to environmental concerns. However, there’s a shift toward renewable energy sources for mining. Large mining operations (mining pools) can dominate the network, threatening decentralization. Proof of Work can be slow and expensive for processing large numbers of transactions, prompting exploration of alternatives like Proof of Stake (PoS).

Solving math problems in Bitcoin mining is valuable because it ensures the security, trust and decentralization of the Bitcoin network. It aligns economic incentives with the maintenance of a transparent, tamper-proof system. While the process has its drawbacks, its significance in enabling a revolutionary decentralized financial system cannot be overstated. Mining is the backbone of Bitcoin’s value proposition as a secure, global and decentralized currency.

Structure: Blocks, Chains and Nodes

• Blocks: Each block contains:
  • Data: Information about the transaction (e.g., sender, receiver, amount).
  • Hash: A unique identifier for the block, generated using a cryptographic algorithm.
  • Previous Block Hash: Links the block to the one before it, forming a chain.
• Chain: A continuous sequence of blocks that forms the blockchain.
• Nodes: Computers in the network that store a copy of the blockchain and validate transactions.

Transaction Process

1. Initiation: A user initiates a transaction by sending data (e.g., cryptocurrency transfer).
2. Broadcast: The transaction is broadcast to the blockchain network, where it is picked up by nodes.
3. Validation:
   • Nodes validate the transaction using consensus mechanisms (e.g., proof of work, proof of stake).
   • Validation ensures the transaction is legitimate and conforms to the blockchain’s rules.
4. Block Formation:
   • Valid transactions are grouped into a block.
   • The block is assigned a unique hash.
5. Adding to the Chain:
   • The new block is linked to the previous block via its hash, forming a chain.
   • The updated blockchain is distributed across all nodes in the network.

Consensus mechanisms ensure agreement among nodes on the validity of transactions. Common mechanisms include Proof of Work (PoW), where miners solve complex mathematical problems to validate transactions and add blocks. Mining requires significant computational power (e.g., Bitcoin).

Proof of Stake (PoS) validators are chosen based on their stake (ownership) in the network. PoS is energy-efficient compared to PoW. Delegated Proof of Stake (DPoS) and Practical Byzantine Fault Tolerance (PBFT), etc., are additional mechanisms that block chain uses to ensure reliability and security.

Key Components of Blockchain

Cryptography ensures data security using encryption techniques. Public and private keys facilitate secure transactions. With the distributed ledger, copies of the blockchain are stored across all nodes in the network. Decentralization eliminates the need for a central authority.

Smart contracts use self-executing contracts with predefined rules and conditions. Automate processes like payments, ensuring efficiency and transparency. The mining process validates transactions and adds them to the blockchain (specific to PoW-based systems).

Public blockchains are open to anyone (e.g., Bitcoin, Ethereum). They are highly decentralized and transparent. Private blockchains have restricted access. They are typically used by organizations for internal processes. They have more control but less decentralization. Consortium blockchain is a hybrid model where a group of organizations manages the network. Consortium blockchain balances transparency and control.

Cryptographic algorithms make data nearly impossible to hack or alter. Every transaction is recorded and visible to participants, ensuring accountability. The security built into blockchain technology eliminates the need to rely on intermediaries, reducing costs and bottlenecks. Immutability ensures data integrity by preventing unauthorized changes. Blockchain technology efficiently automates processes and reduces the time necessary for transactions and verifications.

Problems include networks becoming slow and expensive as the number of transactions grows. Proof of Work mechanisms consume significant energy. Implementing blockchain solutions requires technical expertise. Lack of global standards creates uncertainty in adoption.

Applications of Blockchain

1. Cryptocurrencies:
   • The foundation for digital currencies like Bitcoin and Ethereum.
2. Supply Chain Management:
   • Tracks goods from origin to delivery, ensuring transparency and reducing fraud.
3. Healthcare:
   • Secures patient data and facilitates seamless data sharing among providers.
4. Finance:
   • Enables faster, cheaper cross-border payments and eliminates intermediaries.
5. Real Estate:
   • Simplifies property transactions with smart contracts and secure title management.
6. Voting:
   • Ensures secure, transparent and tamper-proof election processes.
