Ethereum Foundation researchers have raised concerns about "state bloat," which refers to the growing storage requirements for nodes in the Ethereum network. The network's state, which includes account balances, contract storage, and application code, is continually expanding. The Foundation warns that as more data accumulates, running a full node becomes increasingly costly and complex. If the state grows too large, the network risks losing its decentralized nature, making it vulnerable to censorship and operational failures. To tackle this issue, the researchers proposed three approaches. The first, State Expiry, aims to remove inactive data while allowing users to restore it if needed. They noted that around 80% of the state hasn’t been accessed in over a year. The second approach, State Archive, would differentiate between frequently accessed (hot) and rarely accessed (cold) data, improving node performance over time. The last option, Partial Statelessness, suggests that nodes could store only necessary subsets of the state, making it cheaper and easier for more participants to join the network. Moving forward, the Ethereum Foundation is prioritizing practical solutions and inviting developers and infrastructure teams to contribute. They emphasize that these proposals are open for feedback and collaboration, underscoring the importance of community involvement in addressing these challenges. The Foundation is also enhancing its communication on long-term protocol development and has outlined plans for further improvements in node operation and infrastructure.
