The blockchain forking mechanism refers to how changes or divergences in the original blockchain are handled and resolved in a blockchain network.
In a blockchain, each new block contains the data of the previous block and is digitally signed to ensure data integrity and security. When the nodes in the blockchain reach a consensus and add new blocks, these new blocks are integrated into the blockchain and form the new longest valid chain.
