Support for Permissioned Solana Chain / Private Cluster Configuration

[fiv3fingers]

I’d like to request support or clearer documentation for running permissioned Solana chains (private or consortium networks) using the Solana codebase.

Background & Motivation

1. Solana is designed as a high-performance, permissionless blockchain.

2. However, some enterprise and research use cases require permissioned setups where validator participation and transaction submission are restricted.

3. Examples include:

• Consortium blockchains (banks, regulated institutions).
  

• Private testing environments with restricted validator sets.
  

• Oracle networks (similar to Pythnet).
  

Currently, it is possible to fork the Solana codebase and create private clusters, but there is no official documentation or configuration options for setting up a permissioned validator set.
