Proof-of-Stake is a consensus mechanism used by some blockchain networks to validate transactions and create new blocks. In this system, validators are chosen to create new blocks based on the number of coins they hold and are willing to “stake” as collateral. This method is generally considered more energy-efficient than Proof-of-Work.
Context
Proof-of-Stake is a frequent topic in discussions about blockchain scalability and energy consumption, particularly following major network upgrades. Current debates often center on the security implications of different staking models and the potential for wealth concentration among large stakers. The transition of prominent blockchains to Proof-of-Stake protocols is a significant development in the industry.
The Pectra upgrade fundamentally refines Ethereum's staking architecture and introduces native account abstraction, streamlining user interaction and bolstering protocol resilience.
This research establishes a foundational framework for analyzing the economic security of blockchain consensus protocols, quantifying attack costs to enable more robust designs.
This research introduces revelation mechanisms within Proof-of-Stake protocols, fundamentally addressing consensus disputes by incentivizing truthful block proposals.
