Introduction to Blockchain Technology

Study Notes

Key Concepts of Blockchain

Decentralized technology allows for a distributed network, enhancing security and reducing reliance on a single authority.
Digital ledger technology records transactions amongst multiple computers, ensuring transparency and reliability.

Applications Beyond Cryptocurrencies

While blockchain is the backbone of Bitcoin and other cryptocurrencies, its use spans various sectors such as finance, supply chain, healthcare, and voting systems.
Potential for increasing efficiency, transparency, and traceability in various industries through smart contracts and real-time audits.

Security Features

Utilizes cryptographic techniques to secure data, ensuring that once recorded, transactions cannot be altered retroactively without consensus from the network.
Each block contains a cryptographic hash of the previous block, forming a secure chain that enhances data integrity.

Network Consensus

Employs consensus mechanisms (like Proof of Work or Proof of Stake) to validate and confirm transactions across the network.
Reduces the risk of fraud and rogue activities, as tampering with the blockchain requires altering all subsequent blocks in the chain.

Scalability and Performance

Challenges exist in terms of scalability (ability to process transactions quickly and efficiently) and how to manage increasing data volumes with speed.
Ongoing developments aim to address these challenges, ensuring that blockchain can accommodate widespread use across various applications.
