Node key management via HSM / MPC

[przemyslaw]

We must provide a proven scenario where the node operator requires an extra security layer on top of the key management.

Teonite will prepare a document - research about HSM, MPC, TPM open source in the first way.
Teonite will submit this document to Casper to review.
Req:

• available for everyone (100% operators (amazon, hetzner, ovh, selfhosted + details from Telegram group)
• • Dev will share the latest document on operators env.
• • send to Piotr telegram login to add to Validators Guild
• hardware available globally
• ideally provide the ability for multiple nodes to access the same key
• if not hardware -> software keychain solution
• cost analysis of infra per node
• performance should be taken into account
• allow admins / SRE / Devops to access node hosts without access to private keys
• https://casperstats.io/stats/networkdata
• https://casperstats.io/stats/networkdata?tab=nodelist

DoD:

• after finishing the research provide a CEP
