Unlike traditional currencies, which are issued by central banks, Bitcoin has no central monetary authority.
Without diving into the technical details, Bitcoin works on a vast public ledger, also called as a blockchain, where every single confirmed transaction is included as so-called ‘blocks’. As each block enters the system, it is broadcast to the distributed computer network of users for approval. In this way, all users know about each transaction, which prevents stealing and double-spending, where someone spends the same money twice. The process helps blockchain users to trust the system.

As a new user, you can get started with Bitcoin without getting into the technical details. Once you've installed a Bitcoin wallet on your computer or cell phone, it will produce your first Bitcoin address and you can create more at whatever point you require one. You can reveal your addresses to your friends so that they can pay you or vice versa. In fact, this is truly like how email functions, except that Bitcoin addresses ought to be utilized just once.
The whole Bitcoin network depends upon blockchain, which is a shared public ledger. All verified transactions are added in the blockchain. It permits Bitcoin wallets to figure their spendable balance so that new transactions can be verified thereby ensuring they are truly possessed by the spender. The honesty and the sequential order of the blockchain are implemented with cryptography.
A transaction is an exchange of value between Bitcoin wallets that gets added in the blockchain. Bitcoin wallets keep a confidential piece of data called a private key or seed, which is utilized to sign transactions, giving a mathematical verification that they have originated from the owner of the wallet. The signature also keeps the transaction from being modified by anyone once it has been issued. All transactions are broadcast to the network and usually begin to be confirmed within 10-20 minutes, through a procedure called mining.
Mining is a distributed concurrence system that is used to confirm pending transactions by adding them in the blockchain. It upholds a sequential order in the blockchain, secures the neutrality of the network, and enables different computers to agree on the state of the system. To be confirmed, transactions must be packed in a block that fits extremely strict cryptographic principles that will be verified by the system. These principles keep previous blocks from being altered because doing so would disprove all the subsequent blocks. Mining additionally makes what might be compared to a focused lottery that keeps any person from effectively adding new blocks continuously to the blockchain. In this way, no group or individuals can control what is added in the blockchain or replace parts of the blockchain to move back their own spends.
