 While technically one Subnet can validate multiple chains (like the Primary Network validating P-Chain, C-Chain, and X-Chain), **in production it's almost always a 1:1 relationship**, and we strongly recommend keeping it as such for:

 In the Avalanche Network, the P-Chain of the Primary Network is responsible for all validator and Avalanche L1-level operations. The P-Chain supports the creation of new blockchains and Avalanche L1s, the addition of validators to Avalanche L1s, staking operations, and other platform-level operations.

 Each Avalanche validator can register a BLS public key alongside its NodeID on the Avalanche P-Chain. Validators of Avalanche L1s can stake different amounts of the Avalanche L1's staking token. Through the P-Chain, we can determine a weighted set of BLS Public Keys that correspond to the validators of each Avalanche L1 on the Avalanche Network.
