Blockchain
The blockchain is a distributed ledger with growing lists of Record (computer science), records (''blocks'') that are securely linked together via Cryptographic hash function, cryptographic hashes. Each block contains a cryptographic hash of the previous block, a Trusted timestamping, timestamp, and transaction data (generally represented as a Merkle tree, where Node (computer science), data nodes are represented by leaves). Since each block contains information about the previous block, they effectively form a ''chain'' (compare linked list data structure), with each additional block linking to the ones before it. Consequently, blockchain transactions are resistant to alteration because, once recorded, the data in any given block cannot be changed retroactively without altering all subsequent blocks and obtaining network consensus to accept these changes. Blockchains are typically managed by a peer-to-peer, peer-to-peer (P2P) computer network for use as a public distributed led ...

Fiat Money
Fiat money is a type of government-issued currency that is not backed by a precious metal, such as gold or silver, nor by any other tangible asset or commodity. Fiat currency is typically designated by the issuing government to be legal tender, and is authorized by government regulation. Since the end of the Bretton Woods system in 1976 by the Jamaica Accords, the major currencies in the world are fiat money. Fiat money generally does not have intrinsic value and does not have use value. It has value only because the individuals who use it as a unit of account or, in the case of currency, a medium of exchange agree on its value. They trust that it will be accepted by merchants and other people as a means of payment for liabilities. Fiat money is an alternative to commodity money, which is a currency that has intrinsic value because it contains, for example, a precious metal such as gold or silver which is embedded in the coin. Fiat also differs from representative mone ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Bitcoin Mining
The bitcoin protocol is the set of rules that govern the functioning of bitcoin. Its key components and principles are: a peer-to-peer decentralized network with no central oversight; the blockchain technology, a public ledger that records all bitcoin transactions; mining and proof of work, the process to create new bitcoins and verify transactions; and cryptographic security. Users broadcast cryptographically signed messages to the network using bitcoin cryptocurrency wallet software. These messages are proposed transactions, changes to be made in the ledger. Each node has a copy of the ledger's entire transaction history. If a transaction violates the rules of the bitcoin protocol, it is ignored, as transactions only occur when the entire network reaches a consensus that they should take place. This "full network consensus" is achieved when each node on the network verifies the results of a proof-of-work operation called ''mining''. Mining packages groups of transactions i ...
