 title: Validator Requirements
 ---
 
+## Minimum SOL requirements
+
+There is no strict minimum amount of SOL required to run a validator on Solana.
+However a vote account is required, which has a rent-exempt reserve of
+0.02685864 SOL. Voting also requires sending a vote tranasaction for each block
+the validator agrees with, which can cost up to 1.1 SOL per day.
