Study Notes


  • Decentralization is a fundamental principle of blockchain technology, where everyone involved takes a role in maintaining the system.
  • In a decentralized system, there is no central authority in charge, unlike traditional centralized systems.

Centralized vs Decentralized Systems

  • Centralized systems have a single entity in charge, holding the keys to operations and decision-making.
  • Centralized systems have inherent flaws, such as the risk of corruption or failure, which can lead to system collapse.

Blockchain Technology

  • In blockchain technology, every participant (node) has a copy of the entire blockchain and works together to validate new blocks or transactions.
  • Consensus mechanisms enable all participants to agree on the validity of transactions, ensuring the integrity of the blockchain.

Consensus Mechanisms

  • Consensus mechanisms are designed to maintain order in the blockchain network, ensuring accurate and consistent validation of transactions.
  • Types of consensus mechanisms include proof of work and proof of stake, each with their unique virtues and drawbacks.
  • Consensus mechanisms act as a conductor, ensuring every transaction is in harmony with the others, like an orchestra.

Cryptographic Hash Functions

  • Cryptographic hash functions are used to ensure the integrity and security of data within a blockchain.
  • Hash functions provide a unique identity for every block, like a fingerprint, ensuring its integrity and security.
  • These functions convert data into a unique string of characters, and even minor changes in input data result in a dramatically different hash output.
  • Hash functions serve as the guardians of blockchain, fortifying the immutability and tamper resistance of the ledger.

Explore the concept of decentralization, a fundamental principle underlying blockchain technology. Learn about how decentralized systems differ from traditional centralized systems, and the role of decentralization in various sectors like libraries, banks, and government organizations.
