Study Notes
Decentralization
- 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.
