This proposal introduces a simpler design, while sharing a common philosophy and objectives of earlier proposals and the RSK white paper.

The proposal introduces rent as variable fees for accessing state trie. These fees can help

- make storage payments fairer by introducing a _time dimension to storage_ fees
- improve state caching by introducing a _cache hierarchy_
- help secure the network from some IO attacks
- reduce the likelihood of storage spam and _gas arbitrage_
- encourage developers and product designers to treat state storage more judiciously - important for long term scalability, sustainability and fairness
