10 Questions
Which consensus mechanism does Casper introduce?
Proof of stake
What is the purpose of Casper overlay?
To provide additional protections against block reversions
What determines an agent's influence in a proof of stake system?
The number of coins
What type of blockchain consensus algorithms have been researched in recent years?
Proof of stake
What does Casper provide defenses against?
Catastrophic crashes
What is the goal of Casper?
The goal of Casper is to provide a proof of stake-based finality system that overlays an existing proof of work blockchain.
What does Casper combine?
Casper combines proof of stake algorithm research and Byzantine fault tolerant consensus theory.
What protections does the Casper overlay provide?
The Casper overlay provides additional protections against block reversions for almost any proof of work chain.
What is the process for appending and agreeing on new blocks in a proof of stake system?
In a proof of stake system, new blocks are appended and agreed upon through a process where anyone who holds coins inside of the system can participate, and the influence an agent has is proportional to the number of coins (or 'stake').
What are some of the desirable features of the Casper system?
Some of the desirable features of the Casper system are proven defenses against long range revisions and catastrophic crashes.
Test your knowledge on Casper, the proof of stake-based finality system introduced by Vitalik Buterin and Virgil Griffith. Discover how Casper combines proof of stake algorithm research and Byzantine fault tolerant consensus theory to enhance an existing proof of work blockchain.
