Hacknet Servers

This is a very powerful upgrade to Hacknet Nodes. It is unlocked in BitNode 9.

Instead of producing money, Hacknet servers produce hash. This currency can be exchanged for a variety of upgrades that boost most other mechanics of the game.

We can run scripts on them, but it reduces the amount of hash produced.

There are 5 multipliers that affect them:

• hacknet_node_money affects the hash production rate.
• hacknet_node_purchase_cost affects the cost of purchasing a server.
• hacknet_node_ram_cost affects the cost of upgrading RAM.
• hacknet_node_core_cost affects the cost of upgrading core.
• hacknet_node_level_cost affects the cost of upgrading level.

There is no multiplier that affects the cost of upgrading cache.
