Note: proposals are not discussed yet.

ETH 1.x

There are a variety of proposals for what is now known as ETH 1.x -- a series of upgrades to add features in support of the full ETH2 specs. These are all at the proposal / discussion stage, without any of them having been turned into EIPs.

The EthMagicians ETH 1.x Ring has more discussions.


Storage Rent / Pruning

Problem: on chain storage can't be stored forever. Introduce rent, archiving, pruning, or a variety of other methods to minimize live state storage.





Problem: Simulate various parameters of proposed features

Serenity / ETH2

See the ETH2 Specs Github Repo.

The ETH2 Project Management repo holds ongoing notes and meetings.
