In March, Vitalik Buterin even expressed his concerns about “lazy stakers,” or those who engage solely in staking pools rather than solo staking — clearly indicating the relevance of the centralization issue.
At its core, Ethereum represents a shift in the way financial services are designed, accessed, and utilized. However, relying on a few entities continues to introduce risks and questions about how decentralized Ethereum 2.0 really is.
Ethereum’s path towards centralization sets the stage for more severe complications down the line — namely with regulators and reduced network resilience. Ultimately, Ethereum’s future within DeFi and the blockchain ecosystem as a whole hinges on balancing technical advancements while limiting centralization wherever possible. And there are ways to make it achievable.
If implemented correctly, concepts like rainbow staking could further enhance Ethereum’s adaptability while also combatting centralization. In essence, rainbow staking allows users to stake ETH across multiple pools and strategies simultaneously, effectively creating a “rainbow of rewards”, so to speak, that stakers receive while mitigating anti-competitive risks and building a more resilient ecosystem. The ETH validation process is separated into “heavy” and “light” staking — with “heavy” focusing on validation services for finalization and “‘light” staking zeroing in on censorship resistance of transactions.
