The Platform Chain is the metadata blockchain on Avalanche® and coordinates validators, staking, keeps track of active Subnets, and enables the creation of new subnets. The Platform Chain implements the Snowman consensus protocol.

The Platform Chain (P-Chain) is a key component of the Avalanche®. The P-Chain implements the Snowman consensus protocol, which is Avalanche's consensus mechanism, it serves as the metadata blockchain within the Avalanche network and has several important roles:

1. Coordinating Validators: The P-Chain is responsible for coordinating the validators within the Avalanche network. Validators are nodes in the network that participate in the consensus protocol, helping to validate and secure transactions and blocks.

2. Staking: It manages the staking mechanism, which is important for securing and operating the Avalanche network. Users can stake their tokens to support network security and participate in the consensus process.

3. Tracking Active Subnets: Subnets in Avalanche are separate chains within the network that can have their own consensus rules and tokenized assets. The P-Chain keeps track of active/inactive subnets.

4. Creating New Subnets: The P-Chain also enables the creation of new subnets within the Avalanche network. This flexibility allows for the development of specialized subnetworks for various use cases, such as custom blockchains or token ecosystems.

NOTE: When using these addresses, it is best practice to follow upper / lower case sensitivity.
