iota.lib.js.powsrvio - Use powsrv.io PoW with IOTA.js Library

This library is used to add an alternative attachToTangle function to the iota.js library to delegate Proof-of-work to powsrv.io. This enables for users to offload PoW from low-power IoT devices, mobile and desktop devices without capabilities.

Getting Started

Add the package to your project:

npm install powsrv.js

Basic Usage

const remoteATT = require('powsrv.js')
const attachToTangle = remoteATT(5000, "your9api9key")

// Set attachToTangle to your IOTA client
const { composeAPI } = require('@iota/core')
const iota = composeAPI({
  provider: 'http://localhost:14265',
  attachToTangle
})

1. delay: Integer Milliseconds to wait before PoW server timeout. Null value defaults to 5000
2. key: String API key used to get access to powsrv.io.

API Key

Register on my.powsrv.io to get an API key

My first transaction with PoW done by powsrv.io

1. Change to a directory of your choice.
2. Clone or download iota.lib.js.powsrvio
3. Change to the iota.lib.js.powsrvio/examples directory.
4. Install the iota.js core lib with npm install @iota/core.
5. Change the provider in test_transaction_powsrv.js to your node's address.
6. Change your9api9key to your API key
7. Run node test_transaction_powsrv.js (if there is no node.js on your system install it first)
8. The output shuold be like this: Published transaction with tail hash: XNQY...
9. Great, now you are able to send IOTA transactions with super fast PoW.

My first public MAM stream with PoW done by powsrv.io

1. Change to a directory of your choice.
2. Clone or download iota.lib.js.powsrvio
3. Change to the iota.lib.js.powsrvio/examples directory.
4. Install the mam.client.js lib with npm install @iota/mam.
5. Install the iota.js core lib with npm install @iota/core.
6. Change the provider in publishAndFetchPublic.js to your node's address.
7. Change your9api9key to your API key
8. Run node publishAndFetchPublic.js (if there is no node.js on your system install it first)
9. The output shuold be like this: Published { message: 'Message from Alice',timestamp: '2019-2-10 10:54:47' } ...
10. Great, now you are able to publish MAM streams with super fast PoW
