Subsequently, other cryptocurrencies like Ethereum adopted the proof-of-work consensus protocol for use on their platforms. In 2009, the mechanism was adopted by Satoshi Nakamoto, the anonymous creator of Bitcoin, for use as its official consensus protocol. Although the term was first coined in 1999, it was only adapted to financial use in 2004 by Hal Finney. It is mostly used to deter spam attacks, Distributed Denial of Service (DDoS) attacks and other malicious invasions. WHAT IS PROOF-OF-WORK?Ī proof-of-work is a piece of data that shows that a node has successfully carried out the work necessary to add new data to the system. Each block must contain the proof-of-work, verified by other nodes on the Bitcoin network before it can be validated. This form of consensus is intentionally designed to be difficult, so as to stabilize the number of blocks that are added to the blockchain each day. Fortunately, there is a consensus protocol in place, known as the proof-of-work mechanism that ensures accurate validation of transactions and this is where miners come in.
This may seem a bit complex and even confusing because while consensus may be easy to achieve in a small network, it sounds nearly impossible on a network with almost 10,000 active nodes at any given time. When every node has agreed on which version of the blockchain is accurate, that version is appended to the existing copy that each user has. To ensure this, consensus occurs on every single node, no matter how many there are. They also have to accurately account for the additions and deductions to the balances of the nodes on the network. However, for a system to be truly trustless and transparent, its users need a way to verify that transactions have indeed occurred. The idea behind this technology is to ensure a trustless, permissionless, transparent value system that is independent of central authorities. This process ensures that these transactions are confirmed, and pending payments go through.

To update this ledger, new blocks containing new transactions must be appended to the existing blockchain. As the name suggests, a blockchain is made up of a “chain of blocks” which serve as batches for the transactions entered into the ledger. The technology that powers Bitcoin is known as blockchain, a decentralized ledger containing the records of all transactions on the Bitcoin network. Through mining, certain groups of users are also incentivized to ensure the security of the system.
WHAT IS BITCOIN MINING?īitcoin mining is a mechanism used to confirm new Bitcoin transactions as well as introduce new BTC into the network through rewards that miners are paid. To fully understand how BFGMiner works, it is essential to understand what Bitcoin mining is and how exactly it is done. While several great ones exist, BFGMiner is one of the best and most popular mining software.

The main function of these software programs is to run the algorithms that help miners to solve the complex puzzles needed for mining. There are several popular devices associated with mining, such as ASICs and GPUs, but their software counterparts are often overlooked. This is why there is a continuous evolution in Bitcoin mining hardware and software used for the process, to make it easier for miners to work. The process is also extremely competitive.

Unfortunately, while the general protocol of Bitcoin states that anyone is free to mine the cryptocurrency, the costs of power and the devices and software used, are high. This article was originally published on
