The Bitcoin network consists of multiple blocks, each containing multiple transactions. In order to ensure the security of these blocks, the concept of chaining blocks is used in the Bitcoin Blockchain. This means that the hash of the previous block is included in the current block. This creates a chain of blocks, hence the name “Blockchain”.
In other words, each block in the chain is linked to the previous block through its hash. This means that if any modification is made to the data in a block, it will result in a change in the hash of that block. Since the hash of the previous block is included in the current block, a change in the hash of one block will affect all the subsequent blocks in the chain.
This concept of chaining blocks provides an extra layer of security for the transactions stored in the Blockchain. It ensures that once a block is added to the chain, it cannot be modified or deleted without the consensus of the network.
In conclusion, the chaining of blocks is a critical component of the Blockchain technology and is what makes it a secure and tamper-proof ledger of all the transactions in the network.
The blocks created by the miners are linked together to form the public ledger that is widely distributed. Each block in the chain contains several transactions, which have been previously described in the previous sections. The blocks in the chain could come from any miner.
When creating the block chain, each block has the hash of the previous block added to it. This ensures that the block chain remains secure and tamper-proof. A miner will pick up the hash of the previous block, add it to the current block and create a new hash for the block. This newly created block becomes the end of the chain and more blocks are continuously added to it by other miners, making the chain grow longer over time.
