Cryptocurrencies Named such because they use cryptography to secure transactions and control the creation of new units. Uses peer-to-peer networks to decentralize control. All transactions are publicly announced so that they can be verified by the network’s participants. Similar to a stock exchange, though the transactions are visible, the identities of the parties are not disclosed. Transactions take seconds, but verification can take up to 10 minutes.

Bitcoin Mining

Currency “Mining” Mining is the process of spending computing power to process transactions, secure the network, and keep everyone in the system synchronized together. Mining software listens for transactions broadcast through the peer-to-peer network and performs appropriate tasks to process and confirm these transactions. For new transactions to be confirmed, they need to be included in a block along with a mathematical proof of work. Proofs are very hard to generate because there is no way to create them other than by trying billions of calculations per second. As more people start to mine, the difficulty of finding valid blocks is automatically increased by the network to ensure that the average time to find a block remains equal to 10 minutes.
