Zebra checkpoints

Zebra validates settled network upgrades using a list of Mainnet and Testnet block hash checkpoints:

• Mainnet checkpoints
• Testnet checkpoints

Using these checkpoints increases Zebra's security against some attacks.

Update checkpoints

Checkpoint lists are distributed with Zebra, maintainers should update them about every few months to get newer hashes. Here are the exact commands for updating the lists.
