Blockchain - Chaining Blocks

Blocks created by miners are chained together to form a distributed public ledger.

A block in the chain consists of multiple messages (transactions), as shown in Figure 8. A block in the chain may come from any miner. When creating the chain of blocks, we observe that the previous block's hash is added to the current block.

When a miner creates a block, it picks up the hash of the last block in the chain, combines it with its own messages, and creates the hash of the newly created block. As more and more blocks are added to the chain by miners, this newly created block becomes the new end of the chain.
