“最好的比特币（货币结算系统）+ 最好的以太坊（智能合约编程环境）”，2015年10月，“智能合约”概念提出者，密码学家尼克萨博在Twitter上这样评价Rootstock (RSK)。RSK是一个和比特币双向锚定的开源的智能合约平台，矿工还可以通过联合挖矿获得奖励。RSK创始人Diego在自己的领英界面写道，

“经过多年在拉丁美洲促进比特币采用的工作，我意识到，创建一个能够有效为当地亿万无银行账户提供金融服务的基础平台，还缺少一个关键因素。没有智能合约功能，在缺乏信任的环境中降低波动性，执行复杂的业务规则。 ”

单纯使用比特币不可能解决所有问题。因此，Diego在2015年与团队共同创建了RSK，目标是为比特币生态系统实现智能合约、即时支付以及更高的可扩展性，增加比特币生态的价值和可用性。

2018年1月，RSK正式上线。去年底，RSK宣布了被RIF Labs收购的消息，RIF Labs是由RSK创始团队和其他知名业内专家创建的一个开发实验室，它源于在RSK的第三层创建P2P交互的想法。通过合并，RSK为智能合约互操作性打开了大门，因为RIF OS的框架可能允许RSK在未来与其他智能合约平台进行互操作。

除此以外，RSK团队向巴比特介绍，上线一周年来，RSK Smart在各方面获得了成长，包括：

• 联合挖矿（比特币矿工可同时在主链和侧链进行挖矿）算力从5%增长到了超过40%，大大加强了这一侧链的安全性。

• 面向侧链联邦成员成功部署硬件安全模块（HSM）——为成员持有的250个比特币的安全提供支持以支撑两条链之间双向锚定的无缝运作。

• RSKSmart Github代码库有超过2900次任务提交，相当于Bitcoin Core自诞生以来收到的所有任务的15%。

• 用于侧链运作且与比特币1:1挂勾的Smart Bitcoins（RBTC）开始在多家大型交易所上线，例如火币、Bitfinex和Bitso——让开发者更容易获得RBTC。

• RIF OS的上线，提供了一系列P2P基础设施服务以及在RSK网络上用于dApp开发的代码库

• 2018年我们与50多家企业建立了合作关系，包括节点托管服务商（OakNode）、供应链管理公司（Temco和Dexfreight）以及慈善企业（BitGive）。

最近，RSK又有了最新进展：RSK域名服务（RNS）——首个RIF OS目录协议的实现——也上线了，能够通过可读的别名和域名为用户提供了可轻松识别相关资源的能力，例如RSK地址和公钥等。

谈到推出RNS的原因，RSK团队向巴比特介绍，

“现阶段，区块链开发者和用户必须使用十六位且很难识别的地址，而RNS则能创建人类可读的地址别名。举个例子，如果想要搜索你的朋友Alice，你只需要输入“alice.rsk”，而不是“3f84e75ebb8a561e24436eb456463b79afe533fc”。RNS还针对域名注册流程推出了一个竞标系统以确保公正性。在提供功能强大的服务堆栈方面，RNS是先行者，RIF OS协议将集合包括链下支付、数据存储、数据传输和安全通信在内的功能。”

就在RSK上线一周年，推出域名服务之际，RSK团队接受了巴比特专访，除了过去一年取得的进展，他们还分享了对最近大火的Grin等隐私币种的看法，对其他平台如以太坊等智能合约的看法，以及2019年的重要发展目标。以下为采访内容：

8btc：Rootstock whitepaper was published in 2015. Till now, is there any change to the strategy or the goal of RSK? What will be the primary focus of RSK in the future? RSK的整体战略规化从起初到现在经历了什么转变吗？未来的战略重点，每个板块的具体布局是怎样的？

RSK：Since its inception RSK purpose was always to build and integrate decentralized networks and infrastructure to enable Financial Inclusion on a global scale. That mission still remains the same and given that our objective is connected with serving the most vulnerable in our society, security was a fundamental aspect and the reason the Bitcoin Network was chosen to secure RSK Infrastructure.

自诞生以来，RSK始终致力于建立并整合去中心化的网络及基础设施，以实现全球范围内的普惠金融。这一目标始终没有改变。此外，鉴于我们的目标是为社会中最脆弱的人群服务，安全是最重要的因素，这也是我们选择用比特币网络来搭建RSK基础设施的原因。

As we advanced in the pursue of our goals it became clear that to reach them was essential to make blockchain technology scalable and easy to use for developers, traditional organizations and innovators. That’s why RSK founding team together with other recognized industry experts designed and launched RIF OS on top of the RSK Smart Contract Network. RIF OS is the first all-in-one, easy-to-use, blockchain based p2p infrastructure service suite that will bridge the gap between these technologies and mass adoption. The full stack secured by Bitcoin provides high scalability without compromising security.

在此期间，我们发现，要想实现我们的目标，必须首先提升区块链技术的延展性，让开发者、传统机构和创新者用起来都能更加简单。因此，RSK的创始团队和其他知名的业内专家一起研发并推出了基于RSK智能合约网络的RIF OS。RIF OS是首个一体化且易上手的区块链P2P基础设施服务，为技术和普通大众之间搭建了沟通的桥梁。基于比特币的技术堆栈带来了更高的延展性，同时无需在安全方面做出妥协。

RSK：Name Services are key to translate complex technical concepts into user-friendly labels. This is key to reach the non-technical audience, as it enables the end user to easily and reliably verify the identity of the recipient in a transaction or in any context that requires ID validation. To understand the relevance of this protocol we only need to check what happened with DNS, a key enabler for mass adoption in the Internet of Information, today nobody would think about using IP addresses, but everybody remembers their favorite website’s domain by heart.

域名能够将复杂的技术概念转换为用户友好型标签。这对于不精通技术的用户来说是至关重要的，方便终端用户轻松且可靠地验证另一交易方的身份，在其他需要身份验证的场景中同样如此。为了了解这一协议的重要性，我们可以参照域名系统（DNS），其对于网络信息的普及来说非常关键，如今，没有人会记住具体的IP地址，但人人都能写出自己心仪的网站地址。

From the perspective of programming capabilities RSK Network is on par with Ethereum as both natively support Solidity Smart Contracts and the same APIs. These level of compatibility makes seamless for developers to port their Dapps to the RSK Network and leverage on their acquired abilities / knowledge. 从编程方面来看，RSK与以太坊几乎无异，两者都支持Solidity智能合约以及同样的API接口，开发者可以根据需要在两个网络之间实现无缝对接。

From a perspective of security RSK Network is protected by 40% of the Bitcoin Network computing power and uses the same hashing mechanism as Bitcoin which is the safest decentralized network in the world. Although other security models like EOS’ DPoS or Ethereum’s PoW based on general purpose hardware might bring some benefits none of those Networks has been battle tested and custodied so much value as the Bitcoin Network.

从安全角度来看，比特币是世界上最安全的去中心化网络，而RSK网络有40%的比特币算力支持，采用了同样的哈希机制。尽管EOS的DPoS和以太坊的PoW基于通用硬件，其安全模式的确存在优势，但都不具备比特币网络的价值。

RSK is combining the best of Bitcoin and Ethereum under one roof.

RSK结合了比特币和以太坊的优势。

Some interesting facts about the RSK network are:

• Bitcoin Friendly: Bitcoin was the first and, today, the most well-secured blockchain available. • Secure: RSK blockchain is secured by merge-mining, which means that RSK may achieve the same security as Bitcoin in terms of double-spend prevention and settlement finality. • Scalable: RSK can scale up to 100 transactions per second without sacrificing decentralization. • Flexible: Near instant payments allow new use cases, such as retail-ready store payments and micro-credits.

RSK网络的优势如下： - 比特币友好型：比特币不只是首个区块链网络同时也是最安全的。 - 安全：RSK区块链的安全得到了联合挖矿的保障，也就是说，其具备了与比特币同等的安全性，存在双花保护和结算最终性。 - 延展性：RSK每秒能够处理100笔交易，同时不需要在去中心化方面做出妥协。 - 灵活性：近乎即时的支付带来了全新的应用场景，例如零售商店的支付以及微额信贷。

RSK：RSK was the first productive sidechain to Bitcoin achieving an important milestone in interoperability between Blockchains.

RSK是首个实现了多个区块链互操性的比特币侧链。

RSK’s Node supports the Ethereum’s JSON- RPC API making every tool in both ecosystems cross compatible. On top of that RSK team has a Beta version of a bridge with Ethereum that will enable tokens to seamlessly flow between networks.

目前RSK的节点支持基于以太坊JSON- RPC API的所有工具。此外，RSK团队还实现了与以太坊的连接，允许代币在两个网络之间实现无缝流动。

We have been in touch with the Lightning Labs team to study the creation of dual Lightning / Lumino (first implementation of the RIF Payment Protocol) that will enable instant exchange of BTC (bitcoins) for RBTC (smartBitcoins). Related to this our Bangkok Hackathon winner Chiang Mai Lightning Network built a solution to connect RSK and Lightning networks making it easier for developers to get access to Smart Bitcoins (RBTC) today.

我们已经与Lightning Labs团队取得了联系，希望能共同开发双重闪电网络（dual Lightning）或者说Lumino（RIF支付协议的第一版），其能够实现BTC和RBTC之间的即时交易。此外，我们在曼谷举办的黑客马拉松获胜者Chiang Mai Lightning Network搭建的方案能够将RSK和闪电网络连接在一起，方便开发者获得RBTC。

As RSK intends to integrate and provide Smart Contract capabilities to all the networks lacking those capabilities the RSK team has been in talks with teams from Litecoin, Bitcoin Cash and Ravencoin to discuss building bridges with those cryptoeconomies.

RSK还希望那些不具备智能合约功能的网络同样掌握这一能力，目前RSK团队已经与莱特币、BCH以及Ravencoin等团队建立了联系。

Finally RIF OS follows the same objectives as RSK on the construction of an open network of networks for the transfer of value and that’s the reason why all of its services will accept the RIF token which in the future is expected to be ported to other Smart Contract enables Blockchains beyond Ethereum.

最后，RIF OS将秉承RSK的理念，建立一个公开的价值传输网络，因此，所有相关服务都会接受RIF代币支付。未来这一代币将成为对接其他智能合约的入口，不仅限于以太坊。

RSK：RSK, in its current state, is already a scaling solution to Bitcoin as it enables the processing of up to a 100 tps (transactions per second) using smartBitcoins that are fully pegged 1 to 1 with bitcoins. These transactions are settled on average on around 15 seconds. An additional consequence of being able to process more transactions sharing operational costs with Bitcoin is that transaction costs during 2018 were under 2 cents USD during the whole period.

现阶段RSK就是比特币的扩容方案，通过RBTC可以实现100tps的吞吐量。交易平均的结算时间大约15秒。RSK与比特币共享运作成本，2018年的交易成本不足2美分。

On top of the current improvements the future RSK / RIF roadmap includes on-chain compression, transient transactions, full node rewards and off-chain payment processing. When all these improvements are integrated they can enable the processing of tens of thousands of transactions per second in a decentralized and sustainable way.

未来，RSK和RIF在这方面的计划还包括链上压缩、瞬时交易、全节点奖励以及链下支付处理。一旦这些方案成功部署，我们就能看到基于去中心化且可持续的交易，实现数以万计的tps。

RSK：At RSK / RIF Labs we take privacy of the individuals very seriously and have in our roadmap the development of a confidential transaction protocol named Sigilo. We also think this is key to enable certain governmental and corporate use cases that require to obfuscate sensitive information for regulatory of competitive reasons.

RSK和RIF Labs都非常重视个人隐私，我们的发展路线图已经包含了保密交易协议Sigilo的开发。我们还认为在开拓政府和企业应用层面需要混合敏感信息以迎合竞争需求。

RSK：We will continue to work on expanding RSK’s partnership and use cases with special focus on financial inclusion that is at the core of our organization’s purpose.

我们将继续寻找更多的合作伙伴，基于普惠金融的具体需求开拓用例，这是我们的核心目标。

Also we aim to end the year with the first version of an integrated stack between RSK and RIF OS services. Target services include off-chain payments, decentralized data storage, data feeds marketplace, secured communications and naming services.

同时，我们计划在年底之前发布RSK和RIF OS服务集成栈的第一版。目标服务包括链下支付、去中心化数据存储、数据传输市场、安全通讯以及域名服务。

We will continue to strengthen the security of the network by expanding the current 40% of Bitcoin mining hash rate as close as possible to 100%.

我们还会增加联合挖矿的比特币算力，从40%增至近100%，以强化网络安全。

Additionally we will keep expanding the integration with tools, wallets and exchanges, and consolidate our interoperability efforts with other crypto-economies like Ethereum, Litecoin and Bitcoin Cash among others to facilitate broad adoption of the RSK Live Network for developers and organizations.

此外，我们会继续整合更多工具、钱包和交易所，加强与以太坊、莱特币以及BCH等其他加密经济的互操性，让更多的开发者和机构使用RSK网络。
