Cardano RENEW pool is on bare metal servers for 100% Decentralization.
To further decentralize the Cardano ecosystem, RENEW pool has the following philosophy:
- The pool is operated in a server room of a small Swiss IT company. Many larger pools are hosted by large providers like Amazon AWS (see e.g. "Relay Data Centers" on pooltool.io/networkhealth). An outage of this provider, or an action of the provider based on government regulations would mean that all these pools could get instantly affected / harmed.
- The cardano-node software (block producer and 2 relay nodes) runs on bare metal servers at RENEW pool, which basically means that dedicated server hardware is used instead of virtual servers.
- Finally RENEW pool is and will always be a "single pool", which means that the pool operator does run only one pool.
The above diagram (taken from pooltool.io/networkhealth
in November 2022) shows that we need pools running on small providers, to increase decentralization of the network.
