Fundamental Principles Of The Blockchain Technology

The principles of the blockchain depend upon several components such as (Nawari and Ravindran 2019): -

• •

  Distributed database: Every user of a blockchain has access to the full database and its history. Data and information are not controlled by a single organisation. Each participant may independently check the information of its transaction partners without the use of an intermediary.

• •

  Peer-to-peer transmission: Instead, then using a central node, peer-to-peer communication is used. Each node stores information and transmits it to every other node.

• •

  Pseudonymity and transparency: Every transaction and its associated value are visible to everyone with system access. Each node or user on a blockchain is individually identified by an alphanumeric address of at least 30 characters. Users can opt to reveal their names to others or remain anonymous. In a blockchain, transactions take occur between addresses.

• •

  Irreversibility of records: Records cannot be changed because they are connected to all previous transaction records after a transaction is entered into the database and the accounts are updated (thus, the term “chain”). To guarantee that the recording on the database is everlasting, chronologically organized, and accessible to everyone on the network, a number of computational techniques and methods are used.

• •

  Computational logic: Because the ledger is digital, transactions on the blockchain may be linked to computational logic and, in a sense, programmed. As a result, users can create algorithms and rules that start transactions between nodes automatically.
