Bitcoin Mining is the process of adding transaction records to Bitcoins public ledger of past transactions (and a mining rig is a colloquial metaphor for a single computer system that performs the necessary computations for mining. This ledger of past transactions is called the block chain as it is a chain of blocks. The blockchain serves to confirm transactions to the rest of the network as having taken place. Bitcoin nodes use the blockchain to distinguish legitimate Bitcoin transactions from attempts to re-spend coins that have already been spent elsewhere.
Mining is intentionally designed to be resource-intensive and difficult so that the number of blocks found each day by miners remains steady. Individual blocks must contain a proof of work to be considered valid. This proof of ...Please login to read full article
Several cryptocurrencies like Bitcoin and Blockchain technology use the SHA-256 encryption standard.
SHA-2 (Secure Hash Algorithm 2) is a set of cryptographic hash functions designed by the United States National Security Agency (NSA). They are built using the MerkleDamgard structure, from a one-way compression function itself built using the Davies-Meyer structure from a (classified) specialized block cipher.
Cryptographic hash functions are mathematical operations run on digital data by comparing the computed hash (the output from execution of the algorithm) to a known and expected hash value, a person can determine the datas integrity. For example, computing the hash of a downloaded file and comparing the result to a previously published hash result can show whether the do ...Please login to read full article

What Is A Blockchain ?
First of all, what is blockchain and why is it beneficial?
A blockchain is a list of records that continuously grows are known as blocks. Each block has transaction data and a time stamp that are secured through cryptography. Blocks and previous blocks are connected through cryptographic hashes a mathematical algorithm designed as a one-way function which thus creates blockchains. A blockchain, originally block chain, is a continuously growing list of records, called blocks, which are linked and secured using cryptography. Each block typically contains a cryptographic hash of the previous block, a timestamp and transaction data. By design, a blockchain is inherently resistant to modification of the data. It is an open, distributed ledger that can record transactions between two pa ...Please login to read full article

What Are Binary Options
A binary option is a financial option in which the payoff is either some fixed monetary amount or nothing at all.The two main types of binary options are the cash-or-nothing binary option and the asset-or-nothing binary option. The former pays some fixed amount of cash if the option expires in-the-money while the latter pays the value of the underlying security. They are also called all-or-nothing options, digital options (more common in forex/interest rate markets), and fixed return options (FROs) (on the American Stock Exchange).
While binary options may be used in theoretical asset pricing, they are prone to fraud in their applications and hence banned by regulators in many jurisdictions as a form of gambling. Many binary option outlets have been exposed as fraudulent. The U.S. F ...Please login to read full article

What Is A Bitcoin Wallet?
A Bitcoin wallet is a software program where Bitcoins are stored. To be technically accurate, Bitcoins are not stored anywhere there is a private key (secret number) for every Bitcoin address that is saved in the Bitcoin wallet of the person who owns the balance. Bitcoin wallets facilitate sending and receiving Bitcoins and gives ownership of the Bitcoin balance to the user. The Bitcoin wallet comes in many forms desktop, mobile, web and hardware are the four main types of wallets.
A Bitcoin wallet is also referred to as a digital Wallet or Binary Wallet. Establishing such a wallet is an important step in the process of obtaining Bitcoins. Just as Bitcoins are the digital equivalent of cash, a Bitcoin wallet is analogous to a physical wallet. But instead of storing Bitcoins literall ...Please login to read full article
What Is A Bitcoin
To cut through some of the confusion surrounding bitcoin, we need to separate it into two components. On the one hand, you have bitcoin-the-token, a snippet of code that represents ownership of a digital concept - sort of like a virtual IOU. On the other hand, you have bitcoin-the-protocol, a distributed network that maintains a ledger of balances of bitcoin-the-token. Both are referred to as bitcoin.
The system enables payments to be sent between users without passing through a central authority, such as a bank or payment gateway. It is created and held electronically. Bitcoins arent printed, like dollars or euros - theyre produced by computers all around the world, using free software.
It was the first example of what we today call cryptocurrencies, a growing asset class th ...Please login to read full article
What Is Binary
Binary describes a numbering scheme in which there are only two possible values for each digit: 0 and 1. The term also refers to any digital encoding/decoding system in which there are exactly two possible states. In digital data memory, storage, processing, and communications, the 0 and 1 values are sometimes called low and high, respectively.
A bit (short for binary digit) is the smallest unit of data on a computer each bit has a single value of either 1 or 0. Executable (ready-to-run) programs are often identified as binary files and given a file name extension of .bin. Programmers often call executable files binaries.
Binary numbers look strange when they are written out directly. This is because the digits weight increases by powers of 2, rather than by powers of 10. In ...Please login to read full article
Is Cash Safe ?
If you look closely at any Bank of England banknote, you will notice it contains the promise to pay inscription. Our promise to honour the stated face value of our banknotes for all time. Even for banknotes that no longer have legal tender status. The banknotes we produce will always be worth their face value The Bank of England the UKs central bank has been issuing banknotes for more than 300 years. For most of that time, banknotes could be exchanged, on demand, for the equivalent amount of gold. But the link between banknotes and gold, known as the Gold Standard, finally ended in 1931. So nowadays it makes more sense to think of money as a kind of IOU (I owe you). Since then, banknotes have been a form of fiat money: money that is not convertible to gold or any other asset. Fiat money ...Please login to read full article
