How is blockchain developed and working?

Blockchain is a system of recording information in a way that makes it difficult or impossible to change, hack, or cheat the system . A blockchain is essentially a digital ledger of transactions that is duplicated and distributed across the entire network of computer systems on the blockchain.

The block chain is a shared public ledger on which the entire Bitcoin network relies . All confirmed transactions are included in the block chain. It allows Bitcoin wallets to calculate their spendable balance so that new transactions can be verified thereby ensuring they’re actually owned by the spender.

Miners create new blocks on the chain through a process called mining . In a blockchain every block has its own unique nonce and hash, but also references the hash of the previous block in the chain, so mining a block isn’t easy, especially on large chains.
