How Blockchain works step by step?

How Blockchain Transaction Works?

  1. Step 1) Some person requests a transaction.
  2. Step 2) The requested transaction is broadcasted to a P2P network with the help of nodes.
  3. Step 3) The network of nodes validates the transaction and the user’s status with the help of known algorithms.

How Blockchain works simple explanation?

Blockchain will store any kind of data exchange on the platform. So, it’s like a ledger system, where every data exchange has a spot in the log. More so, the data exchanges in the system are called transactions. Once the transaction is verified, it gets a place in the ledger system as a block.

How is a Blockchain created?

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.

How transactions are done in Blockchain?

For a public blockchain, the decision to add a transaction to the chain is made by consensus. This means that the majority of “nodes” (or computers in the network) must agree that the transaction is valid. The people who own the computers in the network are incentivised to verify transactions through rewards.
