How Blockchain Works
Blockchain is a decentralized, distributed ledger technology that records transactions across multiple computers in a secure and transparent manner.
Transaction Initiation
A transaction is initiated by a participant in the network. This could involve transferring cryptocurrency, recording ownership of digital assets, or executing a smart contract.
Transaction Verification
The transaction is verified by nodes in a network using consensus mechanisms like Proof of Work (PoW) or Proof of Stake (PoS).
Block Formation:
Verified transactions are grouped into a block. Each block contains a cryptographic hash of the previous block, creating a chain of blocks (hence the term "blockchain").
Consensus Mechanism
Consensus mechanisms ensure consensus among nodes on transaction validity and blockchain addition order, preventing double-spending and maintaining ledger integrity.
Block Validation and Addition
A block is added to the blockchain in chronological order after being verified by a majority of nodes, creating an immutable record of transactions.
Block Reward and Incentives
Miners are rewarded with cryptocurrency for securing the network and adding new blocks, incentivizing participation and maintaining system integrity.
