Ethereum after The Merge is just the beginning. The core network still processes only 12-15 TPS on its base layer, remains expensive during peak usage, and requires enormous storage for full nodes. The 2026 roadmap phase addresses these with Danksharding (blob storage for L2s) and Verkle Trees (replacing Merkle trees for statelessness).

Proto-Danksharding and the Road to Full Danksharding

EIP-4844 (Proto-Danksharding, implemented March 2024) introduced 'blob transactions' — a new data type allowing L2 rollups to post large batches of transaction data to Ethereum more cheaply than using regular calldata. This immediately reduced Arbitrum and Optimism fees by 10x.
Full Danksharding (in development for 2026-2027) expands this to 64 parallel data shards, each storing compressed L2 transaction data. This enables rollups to handle a combined 100,000+ TPS while settling on Ethereum's secure base layer — the architecture that makes Ethereum's rollup-centric future viable.

Account Abstraction: Transforming Wallet UX

- ✓EIP-4337 and EIP-7702: smart contract wallets at the application layer without protocol changes
- ✓Gasless transactions: dApps can sponsor gas fees for users (no ETH required to transact)
- ✓Social recovery: if you lose your key, trusted contacts can recover wallet without seed phrase
- ✓Session keys: grant dApps limited signing authority for specific time periods
- ✓Batched transactions: execute multiple actions in a single transaction
- ✓Custom security logic: multi-sig requirements, spending limits, time locks at wallet level
