Ethereum’s Post-Merge Roadmap: Scaling, Stateless Nodes, and Ledger Pruning
Summary
The document explains how Ethereum’s transition from proof-of-work to proof-of-stake sets up four groups of planned upgrades: the Surge, Verge, Purge, and Splurge. It also describes how reduced validator rewards and transaction-fee burning could affect ETH supply, while noting that the size of any reduction depends on staking and network activity.
The Surge is presented as a move toward processing more activity on Layer 2, including through shards, with transactions later recorded on Ethereum’s main chain. The Verge would use Verkle trees to reduce the data needed for transaction proofs, potentially making validators easier to run. The Purge would reduce the requirement for nodes to retain historical ledger data, and the Splurge covers other improvements. The article cites projected throughput and cost reductions, but these are estimates tied to upgrades that had not yet been completed. Its account is a roadmap overview rather than an evaluation of implementation progress or investment prospects.
Key ideas
- Ethereum’s Merge changed its consensus mechanism to proof-of-stake and lowered energy use, according to the document.
- Reduced validator issuance combined with fee burning could lower ETH supply, though the outcome depends on network conditions.
- The Surge aims to scale activity through Layer 2 systems and shards that submit transaction data to the main chain.
- Verkle trees could reduce the data validators need to check transactions and support lighter clients.
- The Purge targets the storage burden of retaining the full historical ledger, while the Splurge groups other upgrades.
