openassets-ruby
The implementation of the Open Assets Protocol for Ruby.
Install
gem install openassets-ruby
Configuration
Initialize the connection information to the Bitcoin Core server.
- use mainnet
```ruby require 'openassets'
api = OpenAssets::Api.new(=> 'mainnet', :provider => 'bitcoind', :dust_limit => 600, :default_fees => 10000, :rpc => {:user => 'xxx', :password => 'xxx', :schema => 'http', :port => 8332, :host => 'localhost'})
* **use testnet**
change :network and :port(depends on your server setting).
```ruby
require 'openassets'
api = OpenAssets::Api.new({:network => 'testnet',
:provider => 'bitcoind',
:dust_limit => 600, :default_fees => 10000,
:rpc => {:user => 'xxx', :password => 'xxx', :schema => 'http', :port => 18332, :host => 'localhost'}})
The configuration options are as follows:
| option | describe | default |
|---|---|---|
| network | The using network. "mainnet" or "testnet" | mainnet |
| provider | The RPC server. Specify possible now only "bitcoind". | bitcoind |
| dust_limit | The amount of Bitcoin, which is set to the each output of the Open Assets Protocol(issue or transfer). | 600 (satoshi) |
| default_fees | The transaction fee. (used by issue_asset and send_asset, send_bitcoin ) | 10000 (satoshi) |
| rpc | The access information to the RPC server of Bitcoin Core. | N/A |
API
Currently openassets-ruby support the following API.
- list_unspent
Returns an array of unspent transaction outputs, argument with the asset ID and quantity of each output. ```ruby # get all unspent outputs in the wallet. api.list_unspent
# specify th open asset address. api.list_unspent(['akTfC7D825Cse4NvFiLCy7vr3B6x2Mpq8t6'])
[ { "txid": "1610a1f62597a3ea36e09e78354be22d2a958c1a38ed9e5d3f1c2811ee82dc37", "vout": 1, "address": "1HhJs3JgbiyxC8ktfi6nU4wTqVmrMtCVkG", "oa_address": "akTfC7D825Cse4NvFiLCy7vr3B6x2Mpq8t6", "script": "76a914b7218fe503cd18555255e5b13d4f07f3fd00d0c988ac", "amount": "0.00000600", "confirmations": 8338, "asset_id": "AWo3R89p5REmoSyMWB8AeUmud8456bRxZL", "account": "openassets-ruby", "asset_quantity": "67", "asset_amount": "6.7", "asset_definition_url": "http://goo.gl/fS4mEj" }, ...
Output items are as follows.
|Item|description|
|:---|:---|
|txid|The TXID of the transaction containing the output.|
|address| A P2PKH or P2SH address.|
|oa_address|The Open Asset address.|
|script|The output script.|
|amount|The Bitcoin amount.|
|confirmations|A score indicating the number of blocks on the best block chain that would need to be modified to remove or modify a particular transaction. |
|asset_id|The asset ID is a 160 bits hash, used to uniquely identify the asset stored on the output.|
|account|The name of an account.|
|asset_quantity|The asset quantity is an unsigned integer representing how many units of that asset are stored on the output.|
|asset_amount| The asset amount is the value obtained by converting the asset quantity to the unit of divisibility that are defined in the Asset definition file. |
|asset_definition_url|The url of asset definition file.|
- get_balance
Returns the balance in both bitcoin and colored coin assets for all of the addresses available in your Bitcoin Core wallet. ```ruby # get all balance in the wallet. api.get_balance

Output items are as follows.
|Item|description|
|:---|:---|
|address| A P2PKH or P2SH address.|
|oa_address|The Open Asset address.|
|value|The Bitcoin amount.|
|assets|The array of the assets.|
|asset_id|The asset ID is a 160 bits hash, used to uniquely identify the asset stored on the output.|
|asset_quantity|The asset quantity is an unsigned integer representing how many units of that asset are stored on the output.|

- issue_asset
Creates a transaction for issuing an asset. ```ruby # issue asset # api.issue_asset(, , , , , )
# example address = 'akEJwzkzEFau4t2wjbXoMs7MwtZkB8xixmH' api.issue_asset(address, 150, 'u=https://goo.gl/bmVEuw', address, nil, 'broadcast')
If specified ``output_qty``, the issue output is divided by the number of output_qty.
Ex, amount = 125 and output_qty = 2, the marker output asset quantity is [62, 63] and issue TxOut is two.
* **send_asset**
Creates a transaction for sending an asset from the open asset address to another.
```ruby
# send asset
# api.send_asset(<from open asset address>, <asset ID>, <asset quantity>, <to open asset address>, <fees (The fess in satoshis for the transaction. use 10000 satoshi if specified nil)>, <mode=('broadcast', 'signed', 'unsigned')>, <output_qty default value is 1.>)
# example
from = 'akXDPMMHHBrUrd1fM756M1GSB8viVAwMyBk'
to = 'akTfC7D825Cse4NvFiLCy7vr3B6x2Mpq8t6'
api.send_asset(from, 'AWo3R89p5REmoSyMWB8AeUmud8456bRxZL', 100, to, 10000, 'broadcast')
If specified output_qty, the send output is divided by the number of output_qty.
Ex, asset holding amount = 200, and send amount = 125 and output_qty = 2, the marker output asset quantity is [62, 63, 75] and send TxOut is three. The last of the asset quantity is change asset output.
- send_bitcoin
Creates a transaction for sending bitcoins from an address to another.
This transaction inputs use only uncolored outputs. ```ruby # send bitcoin # api.send_bitcoin(, , , , )
# example from = '14M4kbAtn71P1nnNYuhBDFTNYxa19t1XP6' to = '1MFW7BTwiNbAkmVz4SzAMQXboKYKGSzkq2' api.send_bitcoin(from, 60000, to)
If specified ``output_qty``, the send output is divided by the number of output_qty.
Ex, amount = 60000 and output_qty = 2, send TxOut is two (each value is 30000, 30000) and change TxOut one.
* **get_outputs_from_txid**
Get tx outputs. (use for debug)
```ruby
api.get_outputs_from_txid('3fba8bfb157ae29c293d5bd65c178fec169a87f880e2e62537fcce26612a6aa3')

"vout": 1
},..
- send_assets
Creates a transaction for sending multiple asset from the open asset address to another. ```ruby # send assets # api.send_assets(, , , )
# example from = address_to_oa_address('mrxpeizRrF8ymNx5FrvcGGZVecZjtUFVP3') to = address_to_oa_address('n4MEsSUN8GktDFZzU3V55mP3jWGMN7e4wE') params = [] params << OpenAssets::SendAssetParam.new('oGu4VXx2TU97d9LmPP8PMCkHckkcPqC5RY', 50, to) params << OpenAssets::SendAssetParam.new('oUygwarZqNGrjDvcZUpZdvEc7es6dcs1vs', 4, to) tx = api.send_assets(from, params)
