Engine academy: the origin of blockchain -- bitcoin
When talking about blockchain technology, people tend to think of bitcoin first, because blockchain technology first appeared as the underlying framework technology of bitcoin. So before we explore blockchain technology, let\'s take a brief look at the origin of blockchain -- bitcoin.
The concept of Bitcoin was first proposed by satoshi nakamoto on November 1, 2008, and was formally born on January 3, 2009. On November 1, 2008, when the global financial crisis erupted, a man calling himself Satoshi Nakamoto published a bitcoin white paper on the P2P foundation website, \"bitcoin: a peer-to-peer electronic cash system,\" outlining his new vision for an electronic currency -- bitcoin. On January 3, 2009, the creation block of bitcoin was born.
Different from all the currency, the currency monetary authorities don\'t depend on the specific issue, it is according to the specific algorithm, through a lot of calculation, the currency economy is to use the P2P network composed of many nodes in a distributed database to identify and record all transactions, and use the design of cryptography to ensure currency security of each part. The decentralized nature of P2P and the algorithm itself ensure that bitcoin cannot be manufactured in large quantities to artificially manipulate the value of the currency. Cryptographics-based designs allow bitcoin to be transferred or paid for only by the real owner. This also ensures the anonymity of currency ownership and circulation transactions. The biggest difference between bitcoin and other virtual currencies is that its total number is very limited and extremely rare.
Bitcoin can be circulated around the world. It can be bought and sold on any computer connected to the Internet. Anyone, no matter where they are, can mine, buy, sell or receive bitcoin. On January 5, 2009, bitcoin, which is not controlled by the central bank or any financial institution, was born.
