Blockchain是一个单一的链表吗？
[英]Is Blockchain a single linked list?
问题描述
Seen as datatype, is Blockchain a single linked list? 
看作数据类型，Blockchain是一个单一的链表吗？ As each block refers to the previous block using a hash. 由于每个块使用散列引用前一个块。
Or is it some kind of tree? 还是某种树？

The way a blockchain is represented as a singly linked list. 区块链的表示方式是单链表。 Each block has a hash of the previous block which can be thought of as a pointer to previous block. 每个块都有前一个块的散列，可以将其视为指向前一个块的指针。
Some differences are that in a linked list, there are generally more operations for a linked list that are not available in a blockchain, most notably being able to remove a block and to add a block in the middle of the list/chain. 一些差异在于链接列表中，链接列表通常有更多的操作在区块链中不可用，最明显的是能够删除块并在列表/链的中间添加块。
In the bitcoin blockchain, and probably others, each transaction in the block is stored in a Merkle Tree . 在比特币区块链中，可能还有其他区块中，块中的每个事务都存储在Merkle树中 。 The blockchain is not a tree. 区块链不是树。
