Who created Bitcoin? Bitcoin was invented by an anonymous individual or group operating under the pseudonym Satoshi Nakamoto. In 2008, Satoshi published a white paper outlining the concept and technical details of Bitcoin, including the implementation of a decentralized ledger technology known as the blockchain. The first version of the Bitcoin software was released as open-source in January 2009, and the Bitcoin network was subsequently launched, marking the start of the decentralized digital currency. • How does the Bitcoin network validate transactions? Bitcoin transactions are validated using the Proof-of-Work consensus algorithm and the SHA-256 hashing function. Nodes on the network must reach consensus on transactions for the next block to be added to the blockchain. This is achieved through the contributions of decentralized validators, or miners, who compete to solve cryptographic puzzles to validate transactions and add new blocks, receiving a block reward for their efforts. The cryptographic puzzles are designed to be difficult to solve but easy to verify, ensuring the consensus mechanism is secure and tamper-resistant. This work, or proof, serves as evidence that the node has done the required computation and has reached a consensus with other nodes on the network about the validity of the transactions. The SHA-256 hashing function generates a unique, fixed-length output, or hash, for each input, making it computationally infeasible to manipulate the transaction...

What is Bitcoin? Bitcoin keeps coming back in the headlines. With any Bitcoin price change making news and keeping investors guessing. In countries that accept it, you can buy groceries and clothes just as you would with the local currency. Only bitcoin is entirely digital; no one is carrying actual bitcoins around in their pocket. Bitcoin is divorced from governments and central banks. It's organized through a network known as a blockchain, which is basically an online ledger that keeps a secure record of each transaction and bitcoin price all in one place. Every time anyone buys or sells bitcoin, the swap gets logged. Several hundred of these back-and-forths make up a block. (read more) No one controls these blocks, because blockchains are decentralized across every computer that has a bitcoin wallet, which you only get if you buy bitcoins. Why bother using it? True to its origins as an open, decentralized currency, bitcoin is meant to be a quicker, cheaper, and more reliable form of payment than money tied to individual countries. In addition, it's the only form of money users can theoretically "mine" themselves, if they (and their computers) have the ability. But even for those who don't discover using their own high-powered computers, anyone can buy and sell bitcoins at the bitcoin price they want, typically through online exchanges like Coinbase or LocalBitcoins. A 2015 survey showed bitcoin users tend to be overwhelmingly white and male, but of varying incomes. The ...
