经过多年来对链上和链下扩容方案的研究与积累，RSK团队终于在近期取得了针对网络扩容的重磅进展：作为RIF Payments（支付协议）的重要组件，“RIF Lumino Network”上线了。
“RIF Lumino Network a third-layer solution to the Bitcoin blockchain, enables state channels for every token built on RSK increasing transaction throughput and reducing costs by orders of magnitude.” “RIF Lumino Network是搭建在比特币网络上的“第三层”扩容方案，为所有能够在RSK上流通的通证提供状态通道支持，以此极大的提升交易吞吐量，并带来了量级化的成本缩减。”
RSK创始人Diego也再次肯定了RIF Lumino Network上线的超凡意义
“RIF Lumino Network的上线是我们建立全球金融普惠系统的重大里程碑。对RSK和RIF（RSK实验室已被RIF收购）来说，区块链扩容是一个永恒的命题，因为它是我们能否成功服务亿万（未被服务）用户的关键，它意味着突破传统金融系统的桎梏。”
除此之外，RIF Lumino Network将与我们之前已经上线的RIF域名系统（也在第三层）结合，在未来还将与更多的扩容设计（如Unitrie，LTCP等）进行桥接。随着Lumino Network的上线，RSK团队接受了巴比特专访，给出了更多关于LTCP和新上线的Lumino Network的技术信息。作为以PoW侧链发展而来的平台，他们还分享了对PoS共识的侧链的看法，也畅谈了未来的发展规划。
RSK: The technology of private payments is improving all the time at a never seen pace. Only the last three years we’ve seen the development of new more efficient cryptographic schemes such as zCash, CT, RingCT, Bulletproofs, Sonic, Sigma, Lelantus, Zether, Mobius and AZTEC. We realized about this trend in 2015 and we decided that the best strategy was to focus on having the most secure, cheapest payments and strong foundation for 2nd layer privacy solutions to be developed by third parties, and that’s exactly what happened. I would have been a bad idea to use one of the older protocols, because many of them have shown critical vulnerabilities in the last year (zCoin, Monero, zCash).
Q28btc：What are the major advantages LTCP holds compared to other scaling solutions?LTCP的相比其他扩容手段的核心优势？
RSK：Most other blockchains that are pushing 2nd layer solutions have forgotten that the limits of offchain scalability is given by the possible onchain transaction volume. Every active user needs to be able to perform onchains transactions to enter, top-up and settle payment channels. That’s the real bottleneck. So those projects are scarifying any long-term viability of the platform by increasing the number of onchain transactions without making sure the network keeps being publicly auditable. If you cannot download the blockchain and become a full node with your personal computer, then basically the decentralization nature of the blockchain is gone. It’ has become another centralized financial system. You don’t trust. You verify!
Q38btc：It is said that “Payment Network enabling 5000 tps was launched”, and how many users can thus be served? Could you please give a calculation process?Lumino Network可以帮助支付版块的吞吐量打到约5000 tps，那么预计可以服务到多少的用户呢？能分别给出计算方式吗？
RSK：The actual throughput of any Payment Channel Network (PCN) depends on many factors that are not technological such as the network topology created by users, the usage pattern (sellers vs buyers), amounts transacted, channel capacities. Therefore, it’s not possible to simulate a PCN and predict an exact tps value. What we did was a simulation, in a controlled environment, of multiple intermediate hubs and tens of thousands of users transacting pairwise simultaneously, during a period of one day.
Q48btc：As a two-way pegged, lightening network-like approach, what do you think are your unique selling points?应用了双向锚定的，类似于闪电网络的扩容方式后，RSK与Lumino Network的核心竞争力是什么？
RSK：First, you can perform even cheaper payments of RBTC than in BTC. This is because RSK onchain payments are cheaper, and therefore opening and closing of channels can happen more often and at lower costs.
Q58btc：Is RSK planning to include other scaling solutions in its design? (Using sharding? Beacon chain as to Ethereum？)RSK是否打算将更多的扩容方案纳入设计?
RSK: Our pipeline of proposed improvements (published in our RSKIP repository) include LTCP, Storage Rent, Storage Hibernation, Parallel Transaction Processing, Compact block propagation, Account abstraction, and Ephemeral Data. Once we strengthen the core with these proposals (or better alternatives) we will move to the next step our of scalability roadmap, which is not sharding, but helping on the building of more efficient 2nd layer scaling solutions. 我们现在的扩容和提速手段包括LTCP，存储空间租用（Storage Rent），并行交易处理（Parallel Transaction Processing），致密区块传播（Compact Block Propagation）等等。等我们完成了这一阶段的代码升级，会立刻投入到的阶段的扩容研究和实践中。但我们不会使用分片（Sharding），我们倾向于使用建立在Layer-2（即图一中的RSK网络）之上的更具效率的方式。
Q68btc：“The launch of the RIF Lumino Network is a major milestone in our path to enable a global and inclusive financial system.” Are you planning to partner with more institutions in traditional industry to implement your project? Could you please talk more in detail about your future development?“RIF Lumino Network的上线是实现普惠金融应用系统的重要里程碑。”所以你们是否有计划在传统行业与更多的机构合作？ 可不可以透露一下的未来发展计划？
RSK：We are working with multiple partners on the DEFI (decentralized Finance Industry) space that covers from the creation of stable coins, to insurance and factoring, and we are also working with platforms that are focused on specific industries to combine these building blocks and improve efficiency of the financial sector.
Q78btc：What do you think of recent market? The rise of price of Bitcoin? Will the trend continue?RSK怎么看近期的市场，包括比特币的大涨？行情是否会持续走高？
RSK：Bitcoin goes through phases of expansion triggered by adoption events, followed by speculation which then gives way to strong adjustment and then lateralization for a few months to a couple years, where builds new bottoms. 比特币近期走势上涨是由于应用的需求增多，随后投机者入场，不出意外的话会有一波强势调整，在未来的几个月甚至几年，价格缓慢回落至新的底部。 I don´t think we have hit yet a new adoption wave so very likely the price will adjust in the months to come. 我不认为我们正在经历一轮新的增量需求，所以很有可能几个月后比特币的价格会回落。
Q8What do you think of the recent ‘star projects’, like Cosmos？Do you have some other opinions toward other PoS side chain projects (like Wanchain)?你对近期的一些明星项目，例如Cosmos有什么看法？对其它的PoS机制的侧链项目又有什么看法呢（Wanchain）？
RSK：I think the Cosmos team has done an amazing contribution to the research and development of PoS and deserve the recognition.
