Transactions
This is the primary part of the Bitcoin system. Transactions are not encrypted, since Bitcoin is an open ledger. Any transaction can be publicly seen in the blockchain using any online blockchain explorer. Since addresses are encrypted and encouraged to be unique for every transaction, tracing a user becomes difficult.
Blocks in Bitcoin are made up of transactions that are viewed in a blockchain explorer; each block has the recent transactions that have happened. Every new block goes at the top of the blockchain. Each block has a height number, and the height of the next block is one greater than that of the previous block. The consensus process is commonly known as confirmations on the blockchain explorer.
