Stateless Ethereum

Stateless Ethereum is a vision for the network where nodes do not need to store the entire state to validate blocks. Instead, validators use witness data provided by transaction senders to verify the validity of their transactions.

This allows for a massive reduction in the storage burden for network participants, enabling more users to run validator nodes. The transition requires significant changes to how transactions are constructed and how the protocol handles state access.

It is considered the ultimate solution to the state bloat problem, allowing the network to scale without compromising decentralization. It relies heavily on cryptographic commitments to ensure state integrity.
