-### Validator roles
+### Validator responsibilities and rewards
+
+Ronin Validators share the critical responsibility of ensuring the integrity of all onchain transactions. That means they produce blocks and vote for finality. Ronin has allocated a total of [180M RON](./../../basics/rewards.md) over 8 years to reward Validators for these contributions, and Validators also receive a percentage of Ronin transaction fees.
+
+The rewards are divided into two parts: 85% for finality voting and 15% for block production. All validators vote for finality, but only 22 validators are selected produce blocks in a given epoch. 
+These 22 validators include 12 Governing Validators, elected by the community to ensure network security, and 10 Rotating Validators selected randomly. The probability of being chosen as a Rotating Validator is proportional to the amount of stake held by each validator
+
+After receiving rewards, validators then re-distribute a small percentage to Delegators according to a commission rate, which can range from 5% to 20%.

-There are three validator roles:
 
-* **Validator Candidate:** the role you get after following the steps
-in this guide. Validator Candidates are eligible to be selected as Standard Validators the next day.
-* **Standard Validator:** all validators participate in the finality voting. 
-10 Rotating Validators are randomly selected every 10 minutes based on their staked amount to produce blocks.
-* **Governing Validator:** the validators chosen by the community and
-Sky Mavis to ensure network security. Governing Validators are
-validators by default, and they account for more than half of the
-total validator set, who actively produce blocks.
