The way a blockchain is presented as a separate list. Each block has a hash of the previous block, which can be considered as a pointer to the previous block.
Some differences are that in a linked list there are usually more operations for a linked list that are not available in the block chain, the most noticeable is the ability to delete a block and add a block in the middle of the list / chain.
In a blockchain of bitcoins and possibly others, each transaction in a block is stored in the Merkle Tree . A blockchain is not a tree.
