EIP-1 is in the wrong table and no table exists for EIPs that are both Finalized and Active. Quoting the EIP: > Some Informational and Process EIPs may also have a status of “Active” if they are never meant to be completed. E.g. EIP 1 (this EIP). This can lead to confusion just like it happened [here](https://github.com/ethereum/EIPs/pull/867#issuecomment-364483227). To avoid that I am moving the EIP in the Readme to its own special table.
EIPs 
Ethereum Improvement Proposals (EIPs) describe standards for the Ethereum platform, including core protocol specifications, client APIs, and contract standards.
Contributing
First review EIP-1. Then clone the repository and add your EIP to it. There is a template EIP here. Then submit a Pull Request to Ethereum's EIPs repository.
EIP status terms
- Draft - an EIP that is open for consideration
- Accepted - an EIP that is planned for immediate adoption, i.e. expected to be included in the next hard fork (for Core/Consensus layer EIPs).
- Final - an EIP that has been adopted in a previous hard fork (for Core/Consensus layer EIPs).
- Deferred - an EIP that is not being considered for immediate adoption. May be reconsidered in the future for a subsequent hard fork.
