Study Notes
Consensus Protocols
- Consensus protocols are essential components of Blockchain technology
- They ensure agreement among nodes on the network, preventing any single entity from manipulating the system
Proof of Work (POW)
- POW is a consensus protocol used in Bitcoin and other cryptocurrencies
- It relies on miners competing to solve complex mathematical puzzles to validate transactions and create new blocks
Scalability Aspects of Blockchain Consensus Protocols
- Scalability is a major challenge facing Blockchain technology
- Current consensus protocols, such as POW, can become bottlenecked, limiting transaction throughput and increasing latency
Distributed Consensus
- Distributed consensus is the process of achieving agreement among decentralized systems
- In Blockchain, distributed consensus enables nodes to agree on the state of the network without a central authority
Consensus in Bitcoin
- Consensus is crucial in Bitcoin to prevent double-spending and ensure the integrity of the network
- Bitcoin's consensus protocol, POW, is energy-intensive and has significant environmental implications
Permissioned Blockchains
- Permissioned Blockchains are decentralized networks with restricted access, requiring permission to participate
- Design goals for Permissioned Blockchains include high throughput, low latency, and strong security guarantees
Consensus Protocols for Permissioned Blockchains
- Consensus protocols for Permissioned Blockchains prioritize performance, scalability, and security
- Examples of consensus protocols used in Permissioned Blockchains include Byzantine Fault Tolerance (BFT) and leader-based consensus algorithms
