阿朵币（英文名ardor）是未来币2.0系统的代币。未来币团队在2016年 5月发布阿朵计划（即未来币2.0代币），并在2017年发布全新特性的未来币区块链系统。阿朵ARDR是由老未来币1 比1快照产生，总量10亿，现有的阿朵ARDR是2016年7-10月由未来币快照产生的。
Ardor是一个可扩展的区块链平台。Ardor通过将Nxt划分为锻链和可修剪的子链来解决区块链膨胀问题。使得Ardor主链专注于保护所有主链和处理事务又不会和子链发生业务冲突，科学的架构使得Ardor成为了整个NXT子链生态系统的基础设施。由于它是用Nxt技术构建的，所以Nxt的特性，比如资产交换，分红支付，消息传递，投票，混洗和货币系统将在子链上提供。另外，用户将能够在平台上的子链之间进行某些交叉链接交易。用户可以发行自己的子链，人们可以使用区块链技术，而无需从头开始构建框架。 快速、可扩展性、安全可靠是阿朵的特性，为企业级区块链技术应用打开了新世界的大门。

项目亮点

1、先进的架构
Ardor平台独特的母子架构允许公司使用子链构建产品和服务，同时依靠母链提供的安全性。
2、高效节能
Ardour平台使用证明共识（Proof-of-Stake）共识算法来消除采矿竞争，因此节点可以使用低能耗和经济的硬件。
3、可靠和可维护的产品
Ardor建立在NXT四年的生产经验基础之上，是Java开发的商业应用最流行的开发语言。
4、快速
包含所有子链的每一个block在60s或更少的时间打包。子链交易可以在确认后从区块链中移除，以保持实际区块链的轻量级和高效性。
5、可扩展性
子链交易数据会被修剪，这样使区块大小独立于所有子链。
6、安全性
阿朵由未来币核心开发团队的公司Jelurida开发，未来币是被证实是安全且稳定的。

应用场景

1、提供区块链服务——Ardor将为世界各地的组织和个人开放区块链开发平台。区块链的高门槛即将消失。
2、可管理的区块链容量大小——通过将不影响安全性的事务和数据分离出来，Ardor将解决可扩展性的问题，并将所有不影响安全性的那些事务和数据移动到子链上。Ardor团队将创建第一个子链，以容纳许多的Nxt 1.0工具以及将来的功能。这种小尺寸还具有短的交易时间，因此与比特币相比，进程只需要几分之一的时间来执行功能。
3、分布式的资产交换——在NXT上建立资产交换，Ardor将能够在任何子链上交换任意子链代币的资产。这允许子链彼此交互，并开辟了许多协作机会，并允许跨链资产交易，这是Nxt生态系统中长期要求的功能。
4、分布式的投票和治理制度——将来将成为下放共识的核心。安全和匿名投票将是Nxt平台上所有子链的可用功能。
5、分阶段交易——在执行事务之前，用户可以设置包括投票的最小数目和设定的时间量等多个条件。像Nxt一样，Ardor将使用智能交易。因此，用户只需要提交事务所需的参数和要使用的功能的ID。交易过程也是完全分散的。不需要集中的服务器、服务或应用程序，如Ethereum的Oracle。

 

Ardor is the latest in the growing field of contenders for blockchain as a service (BaaS) providers. Ardor provides the blockchain infrastructure for businesses and institutions to leverage the strengths of blockchain technology without having to invest in developing custom blockchain solutions. Instead, Ardor offers a main chain that handles blockchain security and decentralization plus customizable child chains that come ready to use, right out of the box, for various business applications. Ardor goes beyond Nxt to solve critical issues of blockchain bloat, scalability, and customization. Nxt is a well respected, verified, and established blockchain technology with a comparatively long history and an experienced development team. However, as blockchain usage increases over the coming years Nxt, and other blockchain technologies, will face some fundamental problems with payments, scalability, and customization. The first and most straightforward problem is the use of native tokens for transaction fees. Nxt uses a forging proof of stake system, meaning that the total token supply has already been created and new tokens aren’t created with each block. Instead, the forgers that verify the blocks receive a portion of the transaction fees paid on the network. As such, the transaction fees need to be paid in NXT, even if you’ve created a new currency that’s independent of Nxt, you’ll still need to own NXT in order to pay miners, diluting the value of your own currency. To test Ardor’s capabilities and serve as an example of an operating child chain, the Ardor developers have created Ignis. Ignis will implement all of the customizable features that come from the Nxt code base. Essentially, Ignis will be a proof of concept and could be the first of many more child chains on the Ardor platform. The Ignis ICO recently raised million in funding for development. In the future, Ardor child chains could be used to create equity trading platforms, digital file transfer services, private enterprise blockchain applications, and many more use cases. Ardor’s strengths are quick time to setup and wide customizability, making it a great option for companies looking to leverage blockchain without the resources to dedicate to custom development. Ardor has many architectural advantages. One of them and perhaps the most influential one is that it has been created using Java; one of the most widespread programming languages in the world today. This is definitely a step in the right direction seeing as it becomes ten times easier for a commercial application to succeed if the development language is one which most programmers can relate to.
