 # Crypto.org Mainnet: Running a Validator
 
 
-This is a detailed documentation for setting up a **Validator** on Crypto.org mainnet. Note that while anyone can set up a validator, only the top 100 validators are considered "active" and eligible to receive rewards. See [FAQs](https://github.com/crypto-org-chain/chain-main/discussions/442) for more info.

 ### Step 2-3. Enable STATE-SYNC
 
 
-With  [STATE-SYNC](https://docs.tendermint.com/master/tendermint-core/state-sync.html)  your node will download data related to the head or near the head of the chain and verify the data. This leads to drastically shorter times for joining a network for validator. For **validator**, It will be amazingly fast to sync the near head of the chain and join the network.

 Blocks before state-sync `trust height` will **NOT** be queryable. If you want to run a **full node** or a validator with complete blockchain data; It is not suggested to use state-sync.
