7月4日20点，猎云财经地面讲堂第三十七期约请到天赋少年Jake，现任以太典范（ETC）中心开辟。本期勾当掌管报酬猎云财做生意务总监张修涤，由Anthony Luo翻译。
如下为分享实录（经编纂收拾整顿）：
修涤：大师早晨好！我是猎云财经地面讲堂掌管人张修涤商务总监，猎云财经是猎星散团下的垂直区块链媒体，具有多档人气品牌栏目，深度专访文章也备受业界承认，线上、线下勾当也活期举行。今朝咱们猎云财经2019年的重心放正在矿圈、买卖所生态以及DAPP上。
接上去有请咱们的主讲高朋。
Jake：Hi everyone. This is Jake. Nice to be here.To su妹妹arize, I am a software engineer (and sometimes researcher) working on both Ethereum and Ethereum Classic. I specialize mostly in compilers and virtual machines due to my hobbyist background in operating systems design.
Anthony Luo翻译：大师好，我是Jake。复杂来讲，我是一个工程师（偶然候是研讨员），既开辟ETH, 也开辟ETC。我的特长是编译器以及假造机，由于我团体对于操纵零碎的计划很感兴味。
Jake：At ETC Labs, I work on the SputnikVM JIT compiler, a special type of Ethereum Virtual Machine implementation which translates EVM bytecode to native machine code in order to increase performance significantly.
Anthony Luo翻译：我正在ETC Labs次要担任开辟SputnikVM JIT编译器，这是一种非凡的以太坊假造机，能够将EVM代码编译至当地，年夜年夜晋升功能。
Jake：In addition to SputnikVM, I also am working on LLVM-based compiler infrastructure for the EVM. In the future, this may enable developers writing EVM-based smart contracts to use other languages than Solidity and Vyper. However, there is research to be done into the compatibility of general purpose languages like Rust and C++ with the EVM's design.
With improvements to the EVM such as EIP 615, though, the situation regarding language compatibility will improve substantially.
Anthony Luo翻译：别的，我还担任开辟基于LLVM的EVM根底设备编译器。此后这将年夜小气便开辟者运用除了Solidity以及Vyper的各类言语编写智能合约。固然，经常使用言语比方Rust以及C++与EVM的兼容性也是将来需求研讨的课题。
跟着假造机的提高，比方EIP615，各类言语的兼容性都将年夜年夜晋升。
Jake：I began working on Ethereum in August 2017, when I was 15. At the time, I had been interested in both blockchain and WebAssembly for quite a while.
Anthony Luo翻译：我于2017年8月开端为ETH任务。事先我15岁，但也曾经存眷区块链以及WebAssembly有一段工夫了。
Jake：At Ethereum, I work on the Ewasm project, an initiative to completely replace the EVM with a simpler virtual machine specification called WebAssembly in Ethereum 2.0.This allows us to fully leverage the existing developer toolchains and modern general purpose languages to implement smart contracts and achieve marginal performance improvements.
Anthony Luo翻译：正在Ethereum，我到场的是Ewasm名目，这是一个用Ethereum 2.0中称为WebAssembly的更复杂的假造机标准完整交换EVM的名目。这使咱们可以充沛应用现有的开辟职员东西链以及古代通用言语来完成智能合约并完成边沿功能改良。
修涤：OK，Jake 是一名天赋少年，明天就由他来说讲ETC以后的开展之路。Atlantis 硬分叉的区块高度以及工夫大约是何时?次要的改良有哪些?
Jake：The Atlantis hard fork has entered its testing phase. The block height of Atlantis is now scheduled at #8,772,000 (around September 17).
Anthony Luo翻译：Atlantis硬分叉今朝曾经正在测试阶段，依据今朝的测试状况硬分叉方案发作正在8,772,000的区块高度，大抵工夫为9月17日。
Jake：The Atlantis hard fork introduces many EIPs from Ethereum's Byzantium hard fork, for the purpose of improving compatibility between chains. One example is EIPs 196 and 197, which implement precompiled contracts for operations on the alt_bn128 curve. This allows the use of ZK-SNARKs in ETC contracts.
Anthony Luo翻译：亚特兰蒂斯晋级引入了很多来自Ethereum的拜占庭分叉的EIP，目标是进步两条链之间的兼容性。比方EIP 196以及197，它们能够正在alt_bn128曲线上的履行预编译的合约。这将撑持正在ETC的智能合约中运用ZK-SNARKs。
Jake：In general, Atlantis hard fork included lots of upgrades in ETH Byzantium hard fork, which can improve the infrastructure and compatibility.
Anthony Luo翻译：总的来讲，Atlantis硬分叉包括了很多ETH拜占庭硬分叉的和谈晋级，能够年夜年夜晋升ETC的根底设备及与ETH的兼容性。
修涤：ETH前期会转成 POS，会对于ETC发生甚么影响吗? ETC有无这方面的思索？
Jake：ETC will stick to PoW. ETC co妹妹unity has the consensus that PoW is the safest algorithm. After ETH turns to PoS, more miner will turn to ETC, and of course the hash rate of ETC will increase a lot.
Anthony Luo翻译：ETC将会保持PoW，ETC社区的共鸣以为PoW是今朝为止最平安牢靠的算法。当ETH将算法切换至PoS后，会有良多的矿工挑选ETC挖矿，毫无疑难会添加ETC的算力。
修涤：ETC开辟的SputnikVM功能上是否是优于EVM？详细表现正在哪些方面？
Jake：Based on the test SputnikVM is 10x faster than current EVM.
Anthony Luo翻译： 依据测试后果SputnikVM的速率是EVM的10倍。
修涤：ETC 的次要劣势有哪些?若何吸收更多的开辟者到生态中来?
Jake：The ETC ecosystem is growing quickly. The hard fork will accelerate this growth and lead to a dramatic increase in DApps. This is because it will make ETC compatible with Ethereum, so DApps can operate on ETC for lower gas cost.
Anthony Luo翻译：今朝ETC的生态正在高速生长。此次硬分叉将会减速它的生长并带来有目共睹的DApp添加。正在硬分叉晋级后，ETC的零碎将能更好的ETH兼容，同时因为DApp正在ETC上运转的gas用度更低，这些城市吸收更多的DApp正在ETC上开辟。
修涤：ETC作为币圈里一个绝对成熟的公链，有无一个明白的开展道路图？
Jake：ETC Labs Core made a road map for this year. The ETC development road map has three priorities: (1) interoperability with Ethereum and other blockchains; (2) optimize and improve the blockchain protocol for greater security and functionality; (3) build tools for developers to increase adoption and usage of ETC.
Anthony Luo翻译：ETC Labs Core正在年终公布了往年的道路图。ETC的开辟道路将优先晋升如下三个方面：
1. 与ETH及其余区块链的互操纵性。
2. 经过优化晋级底层和谈晋升平安性及功用性。
3. 经过为开辟者树立更多根底东西，添加ETC的承受度以及运用率。
Jake：For more details you can check our Medium.
Anthony Luo翻译：更多的细节咱们发布正在了Medium博客上。
修涤：这次硬分叉以后，ETC技能上有甚么新的打破以及改良么？将对于ETC DApp使用情况以及技能生态情况有哪些改动？
Jake：There are several important upgrades in Atlantis that will make ETC faster and more secure. It includes optmization codes to process transactions more quickly. It also includes state clearing for empty and dead accounts, which creates a security risk and slows down the network.
Anthony Luo 翻译：Atlantis中含有多项紧张晋级内容，可让ETC收集愈加疾速且平安。此中就包括了减速传输的优化代码。晋级同时还包括了对于空缺账户及合约的形态肃清，防止了它们形成平安成绩及拥挤收集的能够性。
Jake：As I mentioned before, the hard fork will make ETC compatible with Ethereum, so dapps can operate on ETC for lower gas cost. A same developing environment with much higher speed and less gas fee, it's an easy choice.
Anthony Luo 翻译：我以前提到过正在硬分叉晋级后，ETC的零碎将能更好的ETH兼容，同时因为DApp正在ETC上运转的gas用度更低，这些城市招致更多的DApp正在ETC上开辟。相反的开辟情况、更快的速率、更低的gas用度，关于开辟者来讲是一个很复杂的挑选。
修涤：ETH与ETC作为同胞兄弟，以前不断被良多人诟病ETC的开展促进比拟迟缓，本次硬分叉晋级将年夜幅晋升ETC的根底设备功能和以及ETH的兼容性，详细施展阐发正在哪些方面？匆匆使两者收集兼容是出于甚么思索？
Jake：The Atlantis hard fork, as I have mentioned, introduces many EIPs from Ethereum's Byzantium hardfork which have implications for developers of on-chain contracts.
For example, EIP-140 introduces the REVERT opcode, which allows state changes to be reverted without consuming all gas or executing an invalid instruction. Contracts on the ETH chain which make use of REVERT are now portable to ETC.
Another improvement in compatibility comes from the fact that some ETH contracts depend on the STATICCALL opcode introduced with EIP 214.
For example, ERC165, a method used to identify what standard interfaces a contract implements, requires the presence of STATICCALL.
Anthony Luo 翻译：如我后面提到的，亚特兰蒂斯分叉引入了很多来自ETH拜占庭拜占庭的EIP，这些EIP处置链上合约开辟的人具备启迪性意思。
比方，EIP -140引入了REVERT操纵码，它答应正在不用耗局部gas或者履行有效指令的状况下撤消形态变动。
ETH链上运用REVERT的左券如今能够移植到ETC。另有一些兼容性上的改良是由于良多ETH合约依附于EIP 214的STATICCALL操纵码。
比方，ERC165是一种用于辨别合约详细约运用哪些规范接口的办法，条件请求便是要有STATICCALL。
Jake ：ETC Labs wants to improve compatibility with ETH because it seeks to foster closer technical collaboration between the two co妹妹unities. It is simply irrational to undermine technical progress in favor of holding onto old differences. With this direction, I think it is completely plausible that both chains can establish their roles in the space, with their own unique value propositions.
Anthony Luo翻译：ETC Labs但愿改良ETH的兼容性，由于ETC Labs但愿增进两个社区之间更严密的技能协作。为了保存旧的差别而障碍技能提高是完整不睬性的。因而，我以为两条链均可以具备本人的代价主意，建立各自差别的脚色。
修涤：关于后续ETC的开展，你有一些甚么留意能够跟大师分享？
Jake ：One of my expectations for ETC's future development is that we will find a healthy balance of technical progress and adherence to the values on which ETC was founded.
In addition to iterating on concepts that come from Ethereum's co妹妹unity, I also hope that we can devise our own and build on research that has already been done.
With the rate that advancements are made in the blockchain industry, it is difficult for blockchains valuing technical and monetary conservatism to thrive unless they are already established.
Read: BTC. I am confident that ETC, by sacrificing some conservatism in favor of technical progress, can secure its place and value in the future.
Anthony Luo 翻译：我对于ETC将来开展的一个希冀是：正在技能提高以及保持ETC降生时秉承的代价不雅之间找到一个公道的均衡。除汲取Ethereum社区的观点外，我还但愿咱们能够正在已经实现的研讨上构建本人的理念。
按区块链行业的开展速率，技能以及财务上的采纳激进主义很难获得乐成，除了非技能以及财务零碎都曾经树立终了。
即：BTC我置信，假如ETC能放弃一局部激进主义，撑持技能开辟，正在将来必定会有一席之地。
修涤：好的，非常感激Jake的出色分享以及Anehony的翻译。明天讲的比拟偏偏技能没有晓得大师有无成绩，接上去进入到自在发问关键。
社群发问1：今朝灰度本钱对于etc持仓占比很高，对于此你们怎样看呢？
Anthony Luo答：这阐明本钱对于ETC仍是十分看好的，ETC社区不断努力于技能开辟以及去中间化社区办理，以是以前正在推行方面有所完善。跟着技能的不时开展，ETC黑白常有合作力的公链，价钱固然有很年夜的回升空间，这也是为何会收到灰度本钱的注重。
社区发问2：跟着ETH逐渐迁徙至ETH2.0，正在没有远的未来，会有少量的显卡算力被开释。叨教Core Dev Team有何方案应用好这局部算力，以晋升ETC收集的强健性？
Jake：The co妹妹unity discussed about the shift of hashrate before. Most people think after ETH change to PoS, ETC will receive a lot of hashrate from it. Actually it's not how the dev team using the increase, the increase it self helps to improve the strengh of network. Improve it is our goal, what we done like upgrade the protocals helps also.
Anthony Luo 翻译：社区不断有评论辩论算力的迁徙。年夜局部人都以为正在ETH转向PoS后ETC能够取得良多算力撑持。现实上咱们不该该说若何应用这些算力去使收集强健，越多的算力撑持这件事自身便是协助晋升收集的强健的。（关于PoW收集来讲，越多的算力自身就代表越平安）。这是咱们的目的，也是咱们做相似Atlantis这类晋级的初志。
社区发问3：ETC 上的DApp有哪些明星名目呢？
Jake：There are a lot of DApps on ETC now since ETC Labs established. In the Cohort 1 that just finished, I found some interesting projects. BUTTON Wallet is a DApp combining telegram with wallet. The project won a lot of prize of hackathon in ETH SF, ETH Denver, ETH Singapore and ETH Paris. And it's using ETC instead of ETH now.There's also some cool DApps like VREX Lab, Slips, and StatWig. I think everyone should focus on what ETC Labs choose to incubate, they are all chosen from hundreds of projects.
Anthony Luo翻译：自从ETC Labs作为孵化器树立以来，愈来愈多的DApps挑选ETC作为开辟平台。正在方才完毕的第一轮名目孵化中，我看到了很多风趣的名目。比方说Button Wallet这个DApp，分离了Telegram以及钱包的功用。这个名目最后设马上博得了包含ETH旧金山、ETH丹佛、ETH新加涉及ETH巴黎等黑客马拉松奖项。值患上一提的是终极他们挑选了正在ETC长进行开辟。另有良多像Vrex Lab（AR资产市场）、Slips（游戏直播应战平台）、StatWig（物流办理零碎）等都是很酷的名目。我感到大师都该当存眷一下ETC Labs挑选孵化的名目，究竟结果它们都是从上百个名目中锋芒毕露的。
社区发问4：想要问下有些年夜的本钱比拟看好etc，可是良多散户其实不看好，这是甚么缘由呢？
Anthony Luo 答：确实我也正在社区内听到过一些散户没有看好的声响，但这也是无可非议的。这局部散户并非没有看好ETC将来的代价晋升，而是他们寻求的是短时间的收益。ETC没有像一些高控盘的其余名目，不成能不断短时间迸发。ETC是PoW挖矿的去中间化名目，只要靠技能开展、使用添加等一些办法一步一步做到代价晋升。以是良多本钱及一些重视代价投资及区块链实质的投资者，仍是很看好ETC的。
社区发问5：ETC的github上的forkstar数目都没有是良多，活泼度仿佛也没有高（除etclabs孵化的名目外）。ETC的冷落是一般状况吗？
Jake：ETC have several dev teams, all teams even most projects have their own repos. We update the codes in different repos. After a project or update is well finished we merged it to our main repo. That's why the GitHub repo doesn't have lots of updates. Actually, lots of devs like me join ETC now, and the co妹妹unity is active.
Anthony Luo 翻译：ETC有良多开辟团队，每一个团队乃至年夜局部名目都有自力的代码库。咱们普通正在绝对应的代码库更新内容，再局部实现后再同步到ETC的代码库。这便是为何看下来ETC的代码更新数目显患上其实不多。现实上愈来愈多像我如许的开辟者在参加ETC，全部社区实际上是很活泼的。
社区发问6：叨教高朋，ETC将怎么样去面临51%的收集打击?
Jake：ETC Labs Core developed a chain monitoring tool after the 51% attack, so we can find out the risk in advance. We will inform every node to increase the confirm number. Also, the co妹妹unity is always working on increasing the hash rate, which can avoid the attack.
Anthony Luo翻译：ETC Labs Core正在年终发作51%打击后曾经开辟了一套打击监控顺序，能够正在打击倡议时失掉实时预警。咱们将告诉各节点年夜幅晋升买卖确认数，如许能够最年夜水平的障碍打击，防止打击者赢利。固然社区也不断正在努力于晋升ETC收集的全体算力，当打击本钱太高时也能够从本源上防止打击的能够。
