The Transformation of Ethereum Scaling with EIP-4844
The Dencun upgrade and EIP-4844 (Proto-Danksharding) introduced temporary data storage units called Blobs to Ethereum. This reduced transaction gas fees on Layer-2 rollups (such as Arbitrum, Optimism, Base, and ZKsync) by over 90%, fueling massive adoption across decentralized finance.
The Centralized Sequencer Privacy Bottleneck
While Layer-2 transactions inherit Ethereum base layer settlement security, the transaction submission layer differs significantly from L1:
- Centralized Sequencer Nodes: Most L2 rollups currently operate a single centralized sequencer (operated by Offchain Labs, Optimism Foundation, or Coinbase for Base).
- Incoming RPC Telemetry: When your wallet signs an L2 swap, your request is submitted directly to the sequencer RPC endpoint, which captures your connecting IP address and wallet address.
- Blob Batching: The sequencer batches hundreds of user transactions into a single compressed Blob and posts it to Ethereum L1. On L1, individual user IPs are completely stripped, but the L2 sequencer operator retains the original ingestion logs.
How to Enhance L2 Network Privacy
- Use privacy-focused L2 RPC relays that strip client IP headers before forwarding transactions to the sequencer.
- Route your Web3 wallet interactions through encrypted WireGuard VPN tunnels.
