Overview
- Vitalik Buterin laid out the vision in a Sept. 27 blog post that describes Ethereum moving from every node re‑executing transactions toward a model where short cryptographic proofs and data sampling verify results.
- PeerDAS, made live in the December 2025 Fusaka upgrade, is a working example of that change because it lets nodes sample blob data instead of downloading everything and reduces node bandwidth needs.
- The Hegotá upgrade, planned for 2027, is presented as the pivot point that will include priority items such as FOCIL (EIP‑7805) to limit builder censorship and could be the last broadly familiar fork before deeper cryptographic redesigns.
- Research and draft proposals now focus on making proofs efficient and quantum‑safe, including recursive STARK work and ideas like EIP‑8288 to aggregate quantum‑resistant signatures and STARK proofs for compact block verification.
- Operational tradeoffs remain urgent: client teams, validators, custodians, and Layer‑2 operators must coordinate which EIPs fit Hegotá versus later forks while meeting the Ethereum Foundation’s roughly 2029 target for core post‑quantum infrastructure.
