Blockchain is a decentralized ledger that records transactions in a public, immutable way. This means there are no intermediaries like banks or other third-party administrators needed to keep the record of who owns what and monitor those assets. Blockchain users can also instantly verify whether information has not been tampered with or modified after it’s been entered into the blockchain ledger

Introduction: There are many reasons for why individuals want to get their hands on bitcoin, but two stand out as most important factors – its inherent potential for disruptive innovation and easy access through exchanges.
Blockchain is a technology that has been in the news and it’s often used to describe cryptocurrency. What does blockchain mean? The word “blockchain” was coined by Satoshi Nakamoto, the creator of bitcoin. Blockchain is a decentralized ledger which records transactions across many computers in a network.

Miners use a process called mining to create brand new blocks on the chain.
Each block in a blockchain has its own nonce and hash. It also refers to the hash of the preceding block in the chain, making mining a block difficult, especially on large chains.
Miners use this program to tackle the exceedingly difficult arithmetic problem of finding a nonce that generates a valid hash. Because the nonce is only 32 bits long and the hash is 256, there are about 4 billion possible nonce hash combinations to mine before the optimal one is found. Miners are said to have discovered the “golden nonce” when this happens, and their block is added to the chain.
Re-mining the block with the change and the available blocks is required to make a difference to the block earlier in the chain. This is why adjusting blockchain technology is difficult. Consider it “mathematical safety,” since finding golden nonces takes a long time and a lot of computational resources.
When a block is successfully mined, the switch is recognized by the majority of the miner’s nodes, and the network is rewarded monetarily.
Blockchain is a technology that allows people to make and share records of transactions without the need for a third-party. It’s also used in cryptocurrency like Bitcoin. Reference: what is blockchain in cryptocurrency.
