In Bitcoin, there are two parties - miners and node runners. While, the miners are running PoW operations, the node runners are only concerned with maintaining the record of the full ledger. Is there a similar distinction on Solana as well or maintaining full node costs resources similar to running validator mentioned on this page: Validator Requirements?
1 Answer
To run a voting validator (or a full node) on the Solana network, it requires around 3 SOL per epoch.
To run a RPC only validator, it requires no SOL.
Outside of that, there are server costs that depend on where and who you host with. I won't put any providers in here in favor of the Solana team not wanting advertisements in answers, but you can expect anywhere from $600 to upwards of $2k monthly in hosting costs.
