The computing power solves complex puzzles such as math problems for which solutions are easily verified as being correct. The miners are typically rewarded with cryptocurrency and transaction fees. A cryptocurrency (or “crypto”) is a digital currency that can be used to buy goods and services, but uses an online ledger with strong cryptography to secure online transactions. Much of the interest in these unregulated currencies is to trade for profit, with speculators at times driving prices skyward. As its name implies, the Bitcoin blockchain is a digital string of chronologically ordered “blocks” — chunks of code that contain bitcoin transaction data. However, it is important to mention that validating transactions and bitcoin mining are separate processes. Mining can still occur whether transactions are added to the blockchain or not.

In version 0.5 the client moved from the wxWidgets user interface toolkit to Qt, and the whole bundle was referred to as Bitcoin-Qt. After the release of version 0.9, the software bundle was renamed Bitcoin Core to distinguish itself from the underlying network. Bitcoin Core is, perhaps, the best known implementation or client. Alternative clients exist, such as Bitcoin XT, Bitcoin Unlimited, and Parity Bitcoin. As new blocks are mined all the time, the difficulty of modifying a block increases as time passes and the number of subsequent blocks increases. Today, bitcoin mining companies dedicate facilities to housing and operating large amounts of high-performance mining hardware. Sgnum , formerly Burstcoin , is a cryptocurrency that supports smart contracts and digital assets and uses an energy-efficient proof-of-capacity mining algorithm.

Today, there are over 18.7 million BTC in circulation meaning there are just 2.25 million BTC left to enter circulation. However, taking into consideration the halving principle and other network factors like mining difficulty, it’s estimated the last bitcoin will be mined sometime around the year 2140. Bitcoin can be divided into smaller units known as “satoshis” and used for payments, but it’s also considered a store of value like gold.
