📄️ Origin
A blockchain is a decentralized ledger of information built out of a network of independent computers referred to as "nodes".
📄️ Data Structure
A blockchain shares some similarity to a linked list data structure. Both are linear data sequences. Linked lists contain pointers that link to successive nodes. This means when a new node is added to the linked list, the preexisting node gets a reference to the new node. A blockchain is a sequence of blocks that links to the previous block using a cryptographic hash. This means when a new block is added to the chain, it references the preexisting block.
📄️ Features
Blockchain technology is used in the implementation of cyrptocurrencies. As of this writing :
