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.

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.

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...
It is possible to participate in bitcoin mining indirectly, by partially funding a remote mining operation. Cloud mining is separate and distinct from pool mining, because instead of owning hardware and pooling resources with other miners to increase the likelihood of securing profits, cloud mining simply secures funding from investors, essentially, who have a contract to participate in profits of a mining pool in a remote locations based on the bandwidth of Gigahashes/s that they would like to fund (“buy”). Continue reading...
Ethereum has a Turing-complete platform built into it that allows the blockchain to function like a large distributed computer. The Ethereum Virtual Machine is a part of every Ethereum client software on the blockchain, and it allows the interconnected computers to function as one processor. Distributed computation such as this is not really a new thing, but the fact that it allows all developers in Ethereum to decentralized their projects makes this one of the most revolutionary aspects of the Ethereum platform. Continue reading...
It used to be that litecoin mining could only be done by GPU, but now ASIC machines are getting all the glory. For a time, new miners preferred to mine litecoin instead of bitcoin because ASIC miners had rendered old-fashioned GPU mining for Bitcoin unprofitable. During that time, when ASIC machines had not be designed for Litecoin Scrypt mining, anyone with a good enough GPU could profitably mine litecoin with the same computer they used at home, while they were off at work or asleep not using it. If you aren’t aware, GPUs (graphics cards) compute the kinds of functions necessary for mining at many times the speed that CPUs (core processors) alone would. Continue reading...
Individuals who do not have the computing power to compete with large bitcoin mining operations can join a mining pool and split the rewards. Mining pools allow individuals with insufficient computing power to join a mining pool and split the rewards proportionally to the amount of computer power that they contributed. If a user contributes 3% of the computing power that it took for the pool to solve a block, that user will receive 3% of the reward. Continue reading...
When mining on the Ethereum blockchain, you are rewarded in Ether, but you may need to do some calculations to find out it if will be profitable for you. Ethereum mining can still be done profitably, as of the time of this writing, by individuals on their home computers, as long as they have decent hardware. This is no longer the case for Bitcoin, Litecoin, and a few other coins, due to the development of ASIC (application-specific integrated circuits) mining rigs used by the nascent mining industry, which have rendered home computers obsolete and have begun to present a significant centralization threat on the decentralized blockchain. Continue reading...
Setting up a bitcoin miner can be as simple as downloading a mining client program, or as complicated as building a custom rig. Bitcoin mining used to be cheaper and easier to do than it is today, but it can still be relatively simple to execute. In the past, a computer with a CPU could crunch through enough hashes to solve a few blocks and turn a profit. Now, a good GPU, that is, a Graphics Processing Unit card connected to the motherboard of a computer, or a series of GPUs, is par for the course because they can perform many times as many hashes per second than a CPU can alone. This is the case even if the CPU has several cores, and it just has to do with the way that GPUs handle their work. Continue reading...
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. Continue reading...
A Merkle Tree is a technique widely used to create the blocks in blockchains. When records of numerous transactions are blended together into a block and sent to a blockchain to be deciphered and validated, Merkle Trees are generally the design with which they are put together. Ralph Merkle first designed this hashing method in 1979 but didn’t see it popularized for some time. They are sometimes called hash trees. In case you are unaware, the difference between hashes and encryptions is that hashes are not intended to be decryptable unless someone has the original content. Hashes are basically symbols of a certain length generated using the “seed” of the actual content that was fed into the hash function. If the same content is entered as the seed, it will produce the same hash, but any differences will yield a completely different result. Continue reading...
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...
Minority interest is a portion of a company’s stock that is not owned by the parent company, and refers to a type of ownership that generally cannot exert influence over a company’s business decisions. If an outside investor or another company has a less than 50% stake in a company via shares, then they are said to have a minority interest. From an accounting standpoint, only the dividends of a minority interest are counted on a company’s books. If they exert influence over the decision-making, then a percentage of the income may also need to be included. Continue reading...
Dow Theory is perhaps the longest-standing method of market analysis still used in modern finance. It suggests that markets experience primary trends (which last several years), intermediate trends (which last under a year), and minor trends (which last less than a month). Markets are in an upward trend if an average exceeds certain thresholds, followed by a similar movement from another average. Longer, larger trends are considered more predictive than smaller ones, though correctly reading the primary trend in the main goal. Continue reading...
Blockchain technology is a decentralized network structure used to obtain consensus on changes to a ledger shared and distributed throughout a system. Blockchain technology allows for peer-to-peer trust-less validation and record-keeping that is superior to centralized database systems in many situations, in terms of security, reliability, and efficiency. Blockchains tend to be integrated with smart contract technology that serves as the mechanical-legal framework for interactions between the co... Continue reading...
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...

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. Continue reading...
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...
Two words: blockchain technology. Transactions in bitcoin are encoded, packed into a block of other transactions, and all of these are sent out to thousands of computers running blockchain computations, known as hashes. All of these computers are running similar algorithms designed to force honest work and to take time for the computers to complete. The purpose of this step is merely forcing the blockchain to require time, energy, and effort, and to be randomized and decentralized when it is validating transactions. Whichever computer solves it first receives an incentive reward, and the entire blockchain, comprised of all computers running bitcoin client software, then updates the ledger to include the most recent validated transactions.
