Rise JS

Rise JS is a JavaScript library for sending Rise transactions. It's main benefit is that it does not require a locally installed Rise node, and instead utilizes the existing peers on the network. It can be used from the client as a browserify compiled module, or on the server as a standard Node.js module.

Installation

npm install rise-js

Tests

npm test

Tests written using mocha + schedule.js.

Usage

On the client:

<script src="node_modules/rise-js/app.js"></script>

On the server:

var rise = require('rise-js');

Generating a key pair

To generate a public / private key pair from a given passphrase:

var keys = rise.crypto.getKeys("passphrase");

Returning:

{
  publicKey: "5d036a858ce89f844491762eb89e2bfbd50a4a0a0da658e4b2628b25b117ae09",
  privateKey: "2bb80d537b1da3e38bd30361aa855686bde0eacd7162fef6a2…44491762eb89e2bfbd50a4a0a0da658e4b2628b25b117ae09"
}

Generating an address

To generate a unique Rise address from a given public key:

var address = rise.crypto.getAddress("5d036a858ce89f844491762eb89e2bfbd50a4a0a0da658e4b2628b25b117ae09");

Returning:

18160565574430594874L

Creating a transaction

To create a signed transaction object, which can then be posted onto the network:

var amount      = 1000 * Math.pow(10, 8); // 100000000000
var transaction = rise.transaction.createTransaction("1859190791819301L", amount, "passphrase", "secondPassphrase");

Returning:

{
  type: 0, // Transaction type. 0 = Normal transaction.
  amount: 100000000000, // The amount to send expressed as an integer value.
  asset: {}, // Transaction asset, dependent on tx type.
  fee: 100000000, // 0.1 RISE expressed as an integer value.
  id: "500224999259823996", // Transaction ID.
  recipientId: "1859190791819301R", // Recipient ID.
  senderPublicKey: "56e106a1d4a53dbe22cac52fefd8fc4123cfb4ee482f8f25a4fc72eb459b38a5", // Sender's public key.
  signSignature: "03fdd33bed30270b97e77ada44764cc8628f6ad3bbd84718571695262a5a18baa37bd76a62dd25bc21beacd61eaf2c63af0cf34edb0d191d225f4974cd3aa509", // Sender's second passphrase signature.
  signature: "9419ca3cf11ed2e3fa4c63bc9a4dc18b5001648e74522bc0f22bda46a188e462da4785e5c71a43cfc0486af08d447b9340ba8b93258c4c7f50798060fff2d709", // Transaction signature.
  timestamp: 27953413 // Based on UTC time of genesis since epoch.
}

Network identification with Nethash

You need to obtain the nethash in order to be sure you are posting to the right network (testnet, mainnet or others). The nethash is simply the payload hash from the genesisBlock. If no nethash or wrong nethash is provided in the headers, the request will be rejected returning the expected nethash.

{ "success": false, "message": "Request is made on the wrong network", "expected":"e2f8f69ec6ab4b12550a314bd867c46e64e429961bb427514a3a534c602ff467", "received":"wrong-nethash" }

The nethash for a given network can be obtained at the following API endpoint:

/api/blocks/getNetHash

You can also get the nethash from a peer this way:

On the client using jQuery:

var nethash;
$.ajax({
  url: 'https://login.rise.vision/peer/transactions',
  data: JSON.stringify({}),
  dataType: 'json',
  method: 'POST',
  headers: {
    'Content-Type': 'application/json',
    'os': 'linux3.2.0-4-amd64',
    'version': '0.5.1',
    'port': 1,
    'nethash': "wrong-nethash"
  },
  success: function(data) {
    nethash = data.body.expected;
  }
});

From a server using Request:

var nethash;
request({
  url: 'https://login.rise.vision/peer/transactions',
  json: { },
  method: 'POST',
  headers: {
    'Content-Type': 'application/json',
    'os': 'linux3.2.0-4-amd64',
    'version': '0.5.1',
    'port': 1,
    'nethash': "wrong-nethash"
  }
}, function(error, response, body) {
    nethash = body.expected;
  });

Posting a transaction

Transaction objects are sent to /peer/transactions, using the POST method.

Example:

Method: POST
Content-Type: application/json

{
    "transaction" : {
        ...
    }
}

Sending transaction on the Client

Using jQuery:

var success = function(data) {
  console.log(data);
};

$.ajax({
  url: 'https://login.rise.vision/peer/transactions',
  data: JSON.stringify({ transaction: transaction }),
  dataType: 'json',
  method: 'POST',
  headers: {
    'Content-Type': 'application/json',
    'os': 'linux3.2.0-4-amd64',
    'version': '0.5.1',
    'port': 1,
    'nethash':nethash
  },
  success: success
});

Sending transaction on the Server

Using Request:

var request = require('request');

var callback = function(error, response, body) {
  console.log(error || body);
};

request({
  url: 'https://login.rise.vision/peer/transactions',
  json: { transaction: transaction },
  method: 'POST',
  headers: {
    'Content-Type': 'application/json',
    'os': 'linux3.2.0-4-amd64',
    'version': '0.5.1',
    'port': 1,
    'nethash': nethash
  }
}, callback);

Peer Response

Upon successfully accepting a transaction, the receiving node will respond with:

{ "success": true, "result": "5318121831703437738" }

If the transaction is deemed invalid, or an error is encountered, the receiving node will respond with:

{ "success": false, "message": "Error message" }

Other transaction types

Creating a delegate transaction

var transaction = rise.delegate.createDelegate("secret", "username", "secondSecret");

Creating a second signature transaction

var transaction = rise.signature.createTransaction("secret", "secondSecret");

Creating a vote transaction

var transaction = rise.vote.createVote("secret", ["+58199578191950019299181920120128129"], "secondSecret");
