###  constructor

⊕ **new ProofOfWorkWasm**(webPlatform?: *[IWebPlatform](../interfaces/iwebplatform.md)*, timeService?: *`ITimeService`*): [ProofOfWorkWasm](proofofworkwasm.md)

*Overrides ProofOfWorkBase.__constructor*

*Defined in [proofOfWorkWasm.ts:20](https://github.com/iota-pico/pow-wasm/tree/master/src/proofOfWorkWasm.ts#L20*

Create a new instance of ProofOfWork.

**Parameters:**

| Param | Type | Description |
| ------ | ------ | ------ |
| `Optional` webPlatform | [IWebPlatform](../interfaces/iwebplatform.md) |  Provides platform specific functions, optional mostly used for testing. |
| `Optional` timeService | `ITimeService` |  Service to get the time for attachments. |

**Returns:** [ProofOfWorkWasm](proofofworkwasm.md)

## Properties

<a id="max_timestamp_value"></a>

### `<Static>` MAX_TIMESTAMP_VALUE

**● MAX_TIMESTAMP_VALUE**: *`number`*

*Inherited from ProofOfWorkBase.MAX_TIMESTAMP_VALUE*

*Defined in D:/Workarea/iota-pico/pow-wasm/node_modules/@iota-pico/crypto/dist/proofOfWork/proofOfWorkBase.d.ts:12*

The maximum timestamp value used in proof of work.

___

## Methods

<a id="initialize"></a>

###  initialize

▸ **initialize**(): `Promise`<`void`>

*Overrides ProofOfWorkBase.initialize*

*Defined in [proofOfWorkWasm.ts:45](https://github.com/iota-pico/pow-wasm/tree/master/src/proofOfWorkWasm.ts#L45*

Allow the proof of work to perform any initialization. Will throw an exception if the implementation is not supported.

**Returns:** `Promise`<`void`>
Promise.

___
<a id="pow"></a>

###  pow

▸ **pow**(trunkTransaction: *`Hash`*, branchTransaction: *`Hash`*, trytes: *`Trytes`[]*, minWeightMagnitude: *`number`*): `Promise`<`Trytes`[]>

*Inherited from ProofOfWorkBase.pow*

*Defined in D:/Workarea/iota-pico/pow-wasm/node_modules/@iota-pico/crypto/dist/proofOfWork/proofOfWorkBase.d.ts:32*

Perform a proof of work on the data.

**Parameters:**

| Param | Type | Description |
| ------ | ------ | ------ |
| trunkTransaction | `Hash` |  The trunkTransaction to use for the pow. |
| branchTransaction | `Hash` |  The branchTransaction to use for the pow. |
| trytes | `Trytes`[] |  The trytes to perform the pow on. |
| minWeightMagnitude | `number` |  The minimum weight magnitude. |

**Returns:** `Promise`<`Trytes`[]>
The trytes produced by the proof of work.

___
<a id="singlepow"></a>

###  singlePow

▸ **singlePow**(trytes: *`Trytes`*, minWeightMagnitude: *`number`*): `Promise`<`Trytes`>

*Overrides ProofOfWorkBase.singlePow*

*Defined in [proofOfWorkWasm.ts:73](https://github.com/iota-pico/pow-wasm/tree/master/src/proofOfWorkWasm.ts#L73*

Perform a proof of work on a single item.

**Parameters:**

| Param | Type | Description |
| ------ | ------ | ------ |
| trytes | `Trytes` |  The trytes to perform the pow on. |
| minWeightMagnitude | `number` |  The minimum weight magnitude. |

**Returns:** `Promise`<`Trytes`>
The trytes produced by the proof of work.
