Proof of Stake Upgrade

Definition ∞ A Proof of Stake (PoS) upgrade refers to a significant protocol change that transitions a blockchain’s consensus mechanism from Proof of Work (PoW) to Proof of Stake. This alteration changes how new blocks are validated and added to the chain, typically reducing energy consumption and increasing transaction finality.
Context ∞ The Ethereum network’s transition from PoW to PoS, known as “The Merge,” stands as a prominent example of a Proof of Stake upgrade, fundamentally altering its operational economics and environmental impact. Such upgrades are closely watched for their influence on network security, decentralization, and the long-term viability of digital assets.

A large, textured sphere, resembling a celestial body, partially submerges in dark blue liquid, generating dynamic splashes. Smaller white spheres interact with the fluid. This visual metaphorically depicts a decentralized exchange's DEX liquidity pool, where tokenomics drive asset interactions. The main sphere represents a governance token or wrapped asset undergoing smart contract execution, influencing market volatility. The liquid signifies available liquidity, while smaller spheres are other digital assets or stablecoins within the DeFi ecosystem.

Achieving Instantaneous Blockchain Finality by Resolving the Availability-Finality Dilemma

This protocol merges a dynamically available chain with a partially synchronous finality gadget to achieve single-slot finality, eliminating chain reorgs and MEV risks.
