Blockchain Basics
The core of Bitcoin's technology is the blockchain. A blockchain is a distributed ledger that records all Bitcoin transactions across a network of computers. Each block in the chain contains a set of transactions, and once a block is added, it cannot be altered without the consensus of the majority of the network. This immutability makes the blockchain secure. Blocks are linked together using cryptographic hashes. Each block contains the hash of the previous block, creating a chain. If someone tries to change a transaction in an earlier block, the hash of that block and all subsequent blocks will change, alerting the network to the tampering.
Proof - of - Work
Bitcoin uses a consensus mechanism called Proof - of - Work (PoW) to validate transactions and add new blocks to the blockchain. Miners, who are participants in the Bitcoin network, compete to solve a complex mathematical puzzle. The first miner to solve the puzzle gets the right to add a new block to the blockchain and is rewarded with newly minted Bitcoins and transaction fees. The difficulty of the puzzle is adjusted regularly to ensure that a new block is added approximately every 10 minutes. PoW makes it extremely expensive and resource - intensive to try to manipulate the blockchain, as an attacker would need to control more than half of the network's computing power (a 51% attack).
Wallets and Keys
Bitcoin wallets are used to store, send, and receive Bitcoins. There are two types of keys associated with a Bitcoin wallet: public keys and private keys. The public key is like an address that others can use to send you Bitcoins. It is derived from the private key through a cryptographic function. The private key is a secret code that must be kept secure. It is used to sign transactions, proving that the owner of the Bitcoins is authorizing the transfer. Without the private key, it is impossible to spend the Bitcoins associated with a particular public key. Wallets can be software - based (such as mobile or desktop wallets) or hardware - based (physical devices that store keys securely).
Transaction Process
When a user wants to send Bitcoins, they create a transaction in their wallet. The transaction includes the sender's public key, the recipient's public key, and the amount of Bitcoins to be sent. The sender then signs the transaction with their private key, providing proof of ownership. The signed transaction is broadcast to the Bitcoin network. Miners pick up the transaction and include it in a block they are trying to mine. Once the block is added to the blockchain, the transaction is considered confirmed. Confirmations increase the security of the transaction, as it becomes more and more difficult to reverse the transaction with each additional confirmation.
In conclusion, the technology behind Bitcoin is a complex and innovative combination of cryptography, distributed systems, and consensus mechanisms. These technologies work together to create a secure, decentralized, and transparent digital currency system.
