How Does Ethereum Mining Work?
Ethereum mining is the process of solving blocks of encrypted blockchain data using a proof-of-work algorithm and occasionally being rewarded with Ether. Blockchain data is validated and added to the distributed ledger by computers on the network performing the task of “mining,” which is continually attempting to solve puzzles, basically, which each unlock a block of encrypted data containing information about transactions, and, on the Ethereum platform, information about distributed application functions and smart contracts. Once a block is unlocked, the data within is shared with the network and added to the distributed ledger. Continue reading...
How Do You Calculate Mining Profitability?
Mining for cryptocurrency may or may not be profitable for you, but the good news is that you can easily run the numbers. Mining profitability is will primarily depend on the hashrate (mining speed) of your mining hardware, and the amount of energy it takes to run the hardware. Mining software usually comes with system monitors that will tell you with a fair degree of accuracy what the numbers are, and several online calculators exist to help as well. The cost of energy is the main concern, many miners will seek to be near the cheapest sources of energy, such as a hydroelectric plant in Sweden or countries with energy subsidies such as China.

How does Bitcoin Mining Work?
Anyone with a computer connected to the internet can potentially be a bitcoin miner. Bitcoin’s blockchain technology requires that a large network of computers, running the same client software, be used to randomly succeed at validating blocks of encrypted transactions every 10 minutes or so. That’s where bitcoin mining comes in. Mining is the act of letting one’s computer run what’s known as the “hash function” over and over and over in an attempt to crack the codes on the blocks that need validation. The codes that need cracking are all similar and are only difficult enough to require an average of 10 minutes for a random mining computer to get the right answer. The code and the answers are only significant in that they take time to complete, and that they allow the transactions to be validated and added to the ledger of all bitcoin transactions.

How Will Ethereum Scale?
With cryptocurrencies, there is always a question of how the blockchain will scale as technology changes and the currency grows in demand. Blockchains are meant to be immutable, meaning that once a change has been made to it, such as the data for a particular transaction, the record of the transaction cannot be changed or forgotten. This means that, for one thing, the distributed ledger that holds the record of all the transactions will inevitably get larger and larger, and any computer that wishes to be a node may have to download a potential cumbersome file with all that data. Continue reading...
What is the Difference Between Public and Permissioned Blockchains?
Blockchain technology does not always have to be implemented in a public peer-to-peer system. Blockchains rely on a network of computers, representing nodes, that collaborate and distribute the information required for the blockchain to function. The nodes in some blockchains can be established by any computer willing to run the client software for the network. Bitcoin and most cryptocurrencies are intended to function this way: as a public, open-source, permission-less, and trust less network. The nodes are used indiscriminately by the rest of the network as long as the node is performing the functions required of nodes, and this is called a proof-of-work system. When Satoshi Nakamoto coded the first blockchain, his intention was to keep the network functioning with only one tier: “one CPU, one vote.” That vision has encountered obstacles in the form of ASIC mining and other unforeseen circumstances that have empowered some nodes and groups of users over others.

What is Working Capital?
Working capital is computed by subtracting a business’s current liabilities from its current assets. Current means that the assets and liabilities exist within the current year. The appropriate amount of working capital will vary from business to business. Some businesses have a need for a large amount of working capital, and some can maintain a healthy balance sheet with relatively little working capital. Whatever the situation is for a particular business, the approximate calculation for the amount of working capital that they have to use is arrived at by subtracting current liabilities from current assets. Continue reading...
Bitcoin’s Source Code, Part 2: What Does It Mean That Bitcoin Is Open-Source?
Open-source software code can be viewed and changed by anyone, but it actually works in the favor of Bitcoin and other cryptocurrencies. Bitcoin’s source code was uploaded by Satoshi Nakamoto to a code-sharing site called Sourceforge, which enabled anyone to download, use, and modify the code as they saw fit. In fact, he encouraged the community to do so. The fascinating thing about the design of Bitcoin and many other open-source software is that they will work, and will continue to exist, without anyone owning the rights to the code. In most people’s concept of ownership and responsibility, the owner is responsible for maintaining something, for protecting it from attacks, manipulation, vandalism, fraud, etc, and is also responsible for making sure that it is safe for other people to use.

What is Return on Net Assets?
Return on Net Assets is a calculation used to determine how well a company performs, relative to its resources. Return on Net Assets gives investors an idea of how well a company uses its resources to generate profits. Net assets includes not only fixed, tangible assets, but also the net working capital of a business. Working capital is defined as Current Assets minus the Current Liabilities of the business. The net profits for a period are divided by the net assets to arrive at the Return on Net Assets. Continue reading...
What is a Variable Cost?
When budgeting for companies, some expenses are fixed overhead and some are variable, which depend on the amount of work being done. The direct cost of materials and labor are a good example of variable costs that will fluctuate with production levels. There may be an equation that the company can use to reliably predict these variable costs, but they are not fixed costs. From an accounting perspective, of course, these costs would be in separate sections. Fixed costs include warehousing, depreciation, insurances, rent, taxes, salaries, and so forth. These can be put into the budget before anything else happens or any orders have been taken for the year. The variable costs must be taken into account on the fly. Continue reading...
What is a Bitcoin Fork?
The code for most cryptocurrencies is open-source, and the community operates by consensus, so sometimes newly modified code is released that is adopted by some, creating what’s called a fork. A Bitcoin Fork is when the blockchain, made up of interconnected computers holding a distributed and permanent record of all bitcoin transactions up to that point, is offered a modified currency protocol that is adopted by some of the Bitcoin community, which creates a “fork” in the previously longitudinal history of the ledger (i.e. “a fork in the road”), where one ledger continues to grow based on the changed protocol, and one ledger continues to grow with the old protocol still intact. Continue reading...
Who Can Contribute to a Roth IRA?
Most people will be able to contribute to a Roth, but once your income hits certain limits, you may need to find another way. Many people use Roth IRAs to make after-tax retirement contributions that will not be taxable upon withdrawal. If you have earned income under certain income limits, you can fund a Roth for yourself and even for a non-working spouse. Roth IRAs cannot be opened by everyone: the income limits are based on your modified adjusted gross income (MAGI) and marital status. Continue reading...
How Do You Use Ethereum?
When most people ask this question they are actually asking how to use Ether, the main currency of the Ethereum platform. But the Ethereum platform can be used in many ways as well. Ethereum is a platform that can be used by developers to create decentralized applications (dapps), tokens/cryptocurrencies, and basically anything else that can be programmed. It was the front-runner of the race to develop what is sometimes called Crypto 2.0: blockchain technologies that go well beyond singular usage as digital currency and instead reach and revolutionize every aspect of digital technology in the world today. People can and do use Ether, the primary currency of the Ethereum system, to make transactions like a currency, or as an investment. Continue reading...
How is Ripple Different Than Bitcoin and Ethereum?
Ripple’s XRP has the third-largest market cap in the cryptocurrency world, but what gives it value? Ripple Lab’s intent was not to be a store of value or a currency, per se, like Bitcoin. Neither did it intend to be a platform for developers to explore the possibilities of blockchains, like Ethereum. Ripple was always focused on being a payment system, facilitating transfers between banks, currencies, and countries in a way that would not be possible without blockchains. Continue reading...
How Does Blockchain Technology Work?
Blockchains are intended to maintain integrity in the system without anyone needing to monitor or control it. By instituting a system of checks and balances that functions on its own accord through rules programmed into the protocol, and which also makes decisions and keeps records based on consensus throughout a peer-to-peer network, a blockchain oversees its own activities without requiring any trust in a central authority or the other parties involved. Continue reading...
What is Ethereum?
Ethereum is an open-source, public, blockchain-based distributed computing platform. Ethereum provides a cryptocurrency known as ether. Ethereum is a decentralized platform that runs what are known as “smart contracts.” Smart contracts are applications that run on custom built blockchain, which functions on its own accord through rules programmed into the protocol, and which also makes decisions and keeps records based on consensus throughout a peer-to-peer network. A blockchain oversees its own activities without requiring any trust in a central authority or the other parties involved. Continue reading...

What is a Stock?
Buying a stock means taking an ownership position in a publicly traded company. Once you purchase a stock, you become a shareholder. A company has two ways of acquiring capital needed for growth: borrowing it (often in the form of issuing bonds), or selling shares of their company's equity, which is known as stock. In other words, when you buy shares of a company’s stock, you are buying a claim to the company's profit margin, because you are technically a part-owner in the company. Those who hold shares of Common Stock, the most typical form of stock, have voting rights in the election of the company’s board members. Continue reading...
How Does Ethereum Work?
Ethereum uses a blockchain that looks very similar to Bitcoin’s until you get into the details. Ethereum is a platform on which transactions can be made using Ether or other tokens which have been made using the protocol, and smart contracts and decentralized applications (Ðapps) can be executed using the distributed computing power of what’s called the Ethereum Virtual Machine. When viewed from different angles, Ethereum is an open-source coding environment, a market upon which to distribute new blockchain-based applications, and a distributed computing machine that processes functions of the blockchain applications across a broad network. Distributed computing itself is not that new, but distributed computing on a blockchain is. Continue reading...
What is the Absolute Breadth Index?
The Absolute Breadth Index (ABI) is a market breadth indicator, calculated using the absolute value of the difference between the number of advancing stocks and declining stocks to indicate the size of market movement without considering price direction. Larger ABI numbers will indicate more volatility. When breadth is smaller, it means that the market isn’t experiencing significant movement, or movement in a definitive direction. When advances or declines pull away from the other, it indicates the presence of market-wide trends. Continue reading...
What is a commodity etf?
Commodity ETFs are focused on tracking the performance of commodity prices and their derivatives contracts. ETFs are like mutual funds that trade intra-day like stocks, but the volatility of commodities prices can make these equally unpredictable. Commodity ETFs are intended to track the performance and price movements of commodities and their derivatives. All sorts of commodities can and have become part of an ETF offering, from gold to grain, cattle, and coffee, and even US and foreign currencies. Each commodity has its peculiarities and it would be good to know about the market for each commodity that you intend to invest in. Continue reading...
