Introduction
In the rapidly evolving world of blockchain technology, Casper stands out as a revolutionary protocol designed to enhance the performance, security, and scalability of cryptocurrencies. By introducing Proof-of-Stake (PoS) consensus, Casper has brought forth a game-changing approach that promises to overcome the limitations of traditional Proof-of-Work (PoW) mechanisms.
The Evolution of Casper: From Casper CBC to Casper FFG
Initially proposed by Vitalik Buterin, one of Ethereum's co-founders, Casper has undergone several iterations to refine its consensus mechanism. The first iteration, Casper CBC (Correct-By-Construction), aimed to provide instant finality through a voting system. However, its complexity and scalability issues paved the way for Casper FFG (Friendly Finality Gadget), which introduced a more practical and efficient approach.
Casper FFG: Enhanced Security and Scalability
Casper FFG operates on a decentralized network of validators who stake their coins to participate in the consensus process. Validators are randomly selected to propose and finalize new blocks. The more coins a validator stakes, the higher their chance of being chosen.
This design offers several advantages:
Table 1: Casper FFG Parameters
Parameter | Value |
---|---|
Block time | ~12 seconds |
Finality time | ~72 seconds |
Validator stake requirement | ~32 ETH |
Minimum number of validators | 1,000 |
