The world of blockchain and decentralized finance continues to evolve at a rapid pace, with Ethereum at the forefront of innovation. In this insightful discussion, members of the Figment team—Ben and Park—joined Ethereum expert Sreeram Kannan for an in-depth exploration of Ethereum’s transition to proof-of-stake, its foundational principles, and what lies ahead for one of the most influential platforms in Web3.
Moderated by Chris, a long-time crypto native and Figment team member focused on education and governance, this conversation originally aired on Twitter Spaces and offers valuable perspectives for both newcomers and seasoned participants in the Ethereum ecosystem.
The Origins and Purpose of Ethereum
Ethereum was born out of a desire to expand decentralization beyond what Bitcoin had achieved. While Bitcoin pioneered peer-to-peer digital cash, Ethereum introduced a revolutionary concept: programmability through smart contracts.

Ben from Figment explains that Ethereum’s core value proposition lies in enabling developers to build decentralized applications (dApps) on a shared, open-source infrastructure. “Ethereum added programmability to the blockchain—that was the spark,” he says. “But opening it up for anyone to build on was the gasoline that lit the fire.”
This openness has fostered unprecedented innovation, allowing creators worldwide to launch financial protocols, NFT marketplaces, DAOs, and more without needing permission or centralized oversight.
Separating Trust from Innovation
Sreeram Kannan, associate professor at the University of Washington and founder of Eigenlayer, offers a powerful metaphor: Ethereum decouples trust from innovation.
Before Ethereum, every new application required its own trust network—essentially rebuilding consensus from scratch. Ethereum changed that by providing a decentralized trust layer. Developers can now focus solely on building innovative applications, while relying on Ethereum’s robust consensus mechanism to ensure security and execution integrity.
This shift has given rise to what Sreeram calls the pseudonymous economy—a system where contributors don’t need to reveal their identities or gain institutional backing to participate meaningfully. As long as the code is sound, the application functions securely within the network’s trust framework.
Why Ethereum Moved from Proof-of-Work to Proof-of-Stake
Initially modeled after Bitcoin’s proof-of-work (PoW), Ethereum adopted PoW as a proven method for establishing decentralized consensus. However, early in its development, there was strong momentum toward transitioning to proof-of-stake (PoS)—a more efficient and secure alternative.
Sreeram highlights key motivations behind this shift:
- Energy efficiency: Eliminating the massive electricity consumption associated with mining.
- Stronger economic incentives: Introducing slashing conditions that penalize malicious behavior.
- Improved scalability potential: Laying the groundwork for future upgrades like sharding and rollups.
“The move to proof-of-stake wasn’t just about saving energy,” Sreeram notes. “It was about building a more resilient, economically secure network with better long-term sustainability.”
Scaling Ethereum: The Road Ahead
One of the biggest challenges facing Ethereum is scalability—how to process more transactions without compromising decentralization or security. The solution? A rollup-centric roadmap.
Rollups handle computation off-chain while posting transaction data back to Ethereum (Layer 1), ensuring security and verifiability. This approach reduces the load on individual nodes while maintaining trust guarantees.
However, data availability remains a bottleneck. To address this, Ethereum is rolling out critical upgrades:
- EIP-4844 (Proto-Danksharding): Increases data bandwidth by introducing “blobs” that reduce storage requirements for nodes.
- Danksharding (full version): Aims to boost throughput from 80 KB/s to 1.3 MB/s—a 20x improvement—by distributing data verification across the network.
These upgrades are essential for supporting widespread adoption and enabling Layer 2 solutions to scale efficiently.
Unique Strengths of Ethereum’s Proof-of-Stake Design
Ethereum’s PoS protocol stands out due to several advanced features:
- Dynamic availability: The network continues making progress even if many validators go offline.
- Finality and slashing: Malicious actors can be financially penalized through cryptographic proofs.
- Minority protection: Even if a majority of validators act dishonestly, a vigilant minority can initiate slashing events, preserving system integrity.
“What makes Ethereum’s design so compelling,” Sreeram explains, “is its ability to combine elements from different consensus models into something uniquely robust.”
This complexity may seem “baroque” at first glance—but it reflects careful engineering aimed at maximizing decentralization and resilience.
New Roles Emerging Post-Merge
The Merge—the moment Ethereum switched to PoS—didn’t just change consensus; it reshaped the ecosystem’s economic structure. Two key roles have emerged:
1. Proposers vs. Builders
Previously, miners both built and proposed blocks. Now, these functions are being separated:
- Builders optimize transaction ordering (including MEV extraction).
- Proposers select which block to include in the chain.
This creates a competitive market for block construction while preserving decentralization among proposers.
2. Liquid Staking Providers
Locking up ETH for staking reduces capital liquidity—a major barrier for many users. Enter liquid staking, where providers issue tokens (like stETH) representing staked ETH positions.
Users gain exposure to staking rewards while retaining tradable assets. However, Sreeram cautions that while liquid staking improves capital efficiency, it may impact censorship resistance if too much power concentrates in a few providers.
“Decentralization isn’t just about economic security—it’s also about liveness and inclusivity,” he emphasizes.
Frequently Asked Questions
Q: What happens to my staked ETH after The Merge?
A: Staked ETH continues earning rewards under the proof-of-stake system. Withdrawals were enabled post-Merge via protocol upgrades, giving users full control over their assets.
Q: Is it safe to stake with third-party providers?
A: It depends on the provider’s track record, transparency, and security practices. Always research reputation and audit history before delegating your stake.
Q: How does liquid staking affect network security?
A: While it enhances capital efficiency, high concentration among liquid staking providers could reduce decentralization and increase systemic risk if not properly managed.
Q: Can small validators still participate effectively?
A: Yes. Ethereum’s design encourages broad validator participation. Tools like staking pools allow smaller holders to join securely and earn proportional rewards.
Q: What is MEV and why does it matter?
A: Maximal Extractable Value (MEV) refers to profits miners or builders make by reordering transactions. With proposer-builder separation, MEV is becoming a structured part of Ethereum’s economy.
Q: When will full sharding launch?
A: Danksharding is expected in phases over the coming years, following EIP-4844 deployment. It will significantly enhance data availability for rollups.

Final Thoughts
Ethereum’s evolution from proof-of-work to proof-of-stake marks a pivotal moment in blockchain history. By combining programmability, decentralized trust, and continuous innovation in consensus design, Ethereum has positioned itself as the backbone of the Web3 economy.
As new roles emerge—from builders to liquid staking operators—the ecosystem becomes richer and more dynamic. Yet challenges remain, particularly around decentralization trade-offs and long-term sustainability.
For those looking to engage with Ethereum today—whether through staking, developing dApps, or participating in governance—the opportunities have never been greater.
