# Finality

Typically, it takes 3 blocks (\~18 seconds) to be finalized. Considering the potential fluctuations in a PoS network, we provide a more secure method for finality detection.

1. **bevm\_isBlockFinalized**\
   Parameter: EVM block hash\
   Example:

   <pre class="language-bash"><code class="lang-bash"><strong>curl --location 'https://rpc-mainnet-1.bevm.io' \
   </strong>--header 'Content-Type: application/json' \
   --data '{
     "jsonrpc":"2.0",
     "method":"bevm_isBlockFinalized",
     "params":["0x0e5a331fb3cffea6900357a14079eed0e38fbeae633069b831ce124e05b2b0a3"],
     "id":1
   }'
   </code></pre>
2. **bevm\_isTxFinalized**\
   Parameter: EVM transaction hash\
   Example:

   ```bash
   curl --location 'https://rpc-mainnet-1.bevm.io' \
   --header 'Content-Type: application/json' \
   --data '{
     "jsonrpc":"2.0",
     "method":"bevm_isTxFinalized",
     "params":["0xc86fe836e177d05399cb31e7a72a37ca40b287ba4f73ba347fbc8adba7fece62"],
     "id":1
   }'
   ```
