 ## Verifiers

 To verify Semaphore proofs, the [`SemaphoreCore.sol`](https://github.com/semaphore-protocol/semaphore/tree/v2.6.1/packages/contracts/contracts/base/SemaphoreCore.sol) contract requires the address of a deployed verifier contract.
-You can choose to manually deploy the [verifier](https://github.com/semaphore-protocol/semaphore/tree/v2.6.1/packages/contracts/contracts/verifiers) you prefer or you can use one of our [deployed verifiers](/deployed-contracts#verifiers).

 Each verifier name indicates the tree depth that it can verify.
 For example, given a Semaphore proof generated with a tree depth `20`:

 -   The `Verifier20.sol` contract can verify the proof.
-   The [group](/guides/groups) used for the proof can have a maximum `2^20=1048576` members.

cedoor	9c2968eecd	fix(identity): convert hex private key before signing messages The ZK-Kit EdDSA Poseidon package only supports the following private key types: text, buffer. The Semaphore identity supports text and hexadecimal strings. If the identity private key is an hexadicimal string it needs to be converted before being passed to any ZK-Kit function. re #733	2024-03-28 15:52:08 +00:00
