I want to calculate how many groth16 proofs i can fit in a block, Maybe someone can point me how can i verify a groth16 proof in fuel network in its smart contract language ---

Hello @guha-rahul , [here](https://app-testnet.fuel.network/tx/0x12ce8eda6200aad3fd449e1e173bea07663ec089b02ea6ea74c6fe6f4ad30ba6/standard) is an example transaction of a Groth16 proof being verified on the fuel testnet. From here it can be seen that a single groth16 proof takes 593258 in gas. And the current fuel blocks can do 30 million gas. So, in a single block we can do: 30\*1000000 / 593258 = ~51 So, you can say with the current gas limits around 51 Groth16 proofs per block. Things to note. - our block times are 1 second, and will go down and also we might raise gas limits as well in future in alt-DA fuel rollups! - Ideally a lot of recursion would be used in practice as well!
