Partial history expiry announcement

Ethereum has rolled out support for partial history expiry across all execution clients, following EIP-4444, marking a pivotal update that makes node operation lighter, leaner, and more sustainable. By pruning block data pre–The Merge, this reduces the need for massive disk space while preserving the integrity and accessibility of the network.

What’s New

Nodes can now shed 300–500 GB of old block data, fitting comfortably on a 2 TB disk
Pruning is made possible by Ethereum’s move to Proof-of-Stake and weak subjectivity checkpoints, which reduce the need to verify the entire history from genesis

This creates an opportunity to offer tiered node services: lightweight standard nodes + premium archive solutions. The standard business case is the cost-effective node-as-a-service offerings targeting Layer 2s and enterprise clients.
