Blockchain transaction steps

There are four types of blockchain structures:

Blocks are data structures within the blockchain database, where transaction data in a cryptocurrency blockchain are permanently recorded . A block records some or all of the most recent transactions not yet validated by the network. Once the data are validated, the block is closed.

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.
