以下为分享实录(经编辑拾掇):

修涤:大师黄昏好!我是猎云财经空中课堂主理人张修涤商务总监,猎云财经是猎云集团下的笔直区块链媒体,具有众档人气品牌栏目,深度专访作品也备受业界承认,线上、线下运动也按期举办。目前我们猎云财经2019年的重心放矿圈、商业所生态和DAPP上。

接下来有请我们的主讲嘉宾。

Jake:Hi everyone. This is Jake. Nice to be here.To summarize, 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。简单来说,我是一个工程师(有时分是研讨员),既开辟ETH, 也开辟ETC。我的特长是编译器和虚拟机,因为我私人对操作系统的计划很感兴味。

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ETC Labs主要认真开辟SputnikVM JIT编译器,这是一种特别的以太坊虚拟机,可以将EVM代码编译至当地,大大晋升功用。

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:另外,我还认真开辟基于LLVM的EVM根底方法编译器。以后这将大大便当开辟者运用除Solidity和Vyper的种种言语编写智能合约。当然,常用言语比如Rust和C++与EVM的兼容性也是未来需求研讨的课题。

跟着虚拟机的进步,比如EIP615,种种言语的兼容性都将大大晋升。

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义务。当时我15岁,但也曾经体恤区块链和WebAssembly有一段时间了。

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:Ethereum,我到场的是Ewasm项目,这是一个用Ethereum 2.0中称为WebAssembly的更简单的虚拟机标准完备交换EVM的项目。这使我们可以充沛应用现有的开辟职员东西链和当代通用言语来完成智能合约并完成边际功用改良。

硬分叉已测试阶段

修涤:OK,Jake 是一位禀赋少年,本日就由他来讲讲ETC之后的开展之道。Atlantis 硬分叉的区块高度和时间大约是什么时分?主要的改良有哪些?

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硬分叉目前曾经测试阶段,依据目前的测试状况硬分叉方案爆发8,772,000的区块高度,大致时间为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:亚特兰蒂斯升级引入了许众来自Ethereum的拜占庭分叉的EIP,目标是进步两条链之间的兼容性。比如EIP 196和197,它们可以alt_bn128弧线上的施行预编译的合约。这将支撑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:总的来说,Atlantis硬分叉包罗了许众ETH拜占庭硬分叉的条约升级,可以大大晋升ETC的根底方法及与ETH的兼容性。

ETC生态高速孕育

修涤:ETH后期会转成 POS,会对ETC发生什么影响吗? ETC有没有这方面的思索?

Jake:ETC will stick to PoW. ETC community 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社区的共鸣认为PoW是目前为止最平安牢靠的算法。当ETH将算法切换至PoS后,会有许众的矿工挑选ETC挖矿,毫无疑问会添加ETC的算力。

修涤:ETC开辟的SputnikVM功用上是不是优于EVM?精细表示哪些方面?

Jake:Based on the test SputnikVM is 10x faster than current EVM.

Anthony Luo翻译: 依据测试结果SputnikVM的速率是EVM的10倍。

修涤:ETC 的主要优势有哪些?怎样吸引更众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:目前ETC的生态高速孕育。此次硬分叉将会加速它的孕育并带来引人注目标DApp添加。硬分叉升级后,ETC的系统将能更好的ETH兼容,同时因为DAppETC上运转的gas费用更低,这些都会吸引更众的DAppETC上开辟。

修涤:ETC举措币圈里一个相对成熟的公链,有没有一个明晰的开展道线图?

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年头发布了本年的道线图。ETC的开辟道线将优先晋升以下三个方面:

1. 与ETH及其他区块链的互操作性。

2. 通过优化升级底层条约晋升平安性及功用性。

3. 通过为开辟者修立更众根底东西,添加ETC的承受度和运用率。

Jake:For more details you can check our Medium.

Anthony Luo翻译:更众的细节我们发布了Medium博客上。

ETC收集更速、更平安

修涤:此次硬分叉之后,ETC技能上有什么新的打破和改良么?将对ETC DApp运用状况和技能生态状况有哪些改动?

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中含有众项主要升级实质,可以让ETC收集更加疾速且平安。此中就包罗了加速传输的优化代码。升级同时还包罗了对空白账户及合约的形态肃清,避免了它们变成平安题目及拥堵收集的可以性。

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:我之条件到过硬分叉升级后,ETC的系统将能更好的ETH兼容,同时因为DAppETC上运转的gas费用更低,这些都会导致更众的DAppETC上开辟。相同的开辟状况、更速的速率、更低的gas费用,关于开辟者来说是一个很简单的挑选。

修涤:ETH与ETC举措同胞兄弟,之前不停被许众人诟病ETC的开展促进比较迟缓,本次硬分叉升级将大幅晋升ETC的根底方法功用以及和ETH的兼容性,精细外现哪些方面?促使二者收集兼容是出于什么思索?

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:如我前面提到的,亚特兰蒂斯分叉引入了许众来自ETH拜占庭拜占庭的EIP,这些EIP从事链上合约开辟的人具有开辟性原理。

比如,EIP -140引入了REVERT操作码,它容许不消耗通通gas或施行无效指令的状况下消弭形态更改。

ETH链上运用REVERT的契约现可以移植到ETC。另有少许兼容性上的改良是因为许众ETH合约依赖于EIP 214的STATICCALL操作码。

比如,ERC165是一种用于识别合约精细约运用哪些标准接口的方法,前摘请求便是要有STATICCALL。

Jake :ETC Labs wants to improve compatibility with ETH because it seeks to foster closer technical collaboration between the two communities. 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期望改良ETH的兼容性,因为ETC Labs期望增进两个社区之间更厉密的技能协作。为了保管旧的差别而妨碍技能进步是完备不睬性的。于是,我认为两条链都可以具有本人的代价主意,确立各自差别的脚色。

修涤:关于后续ETC的开展,你有少许什么寄望可以跟大师分享?

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 community, 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ETC未来开展的一个希冀是:技能进步和保持ETC降生时秉持的代价观之间找到一个合理的均衡。除了吸取Ethereum社区的看法外,我还期望我们可以已完毕的研讨上构修本人的理念。

按区块链行业的开展速率,技能和财务上的接纳保守主义很难取得成功,除非技能和财务系统都曾经修立完毕。

即:BTC我置信,假如ETC能摒弃一部分保守主义,支撑技能开辟,未来必定会有一席之地。

修涤:好的,十分感谢Jake的精美分享和Anehony的翻译。本日讲的比较偏技能不晓得大师有没有题目,接下来进入到自提问要害。

十分有逐鹿力的公链

社群提问1:目前灰度资本对etc持仓占比很高,对此你们怎样看呢?

Anthony Luo答:这阐明资本对ETC还好坏常看好的,ETC社区不停努力于技能开辟和去中心化社区办理,以是之前推行方面有所缺少。跟着技能的不时开展,ETC好坏常有逐鹿力的公链,价钱当然有很大的上升空间,这也是为什么会收到灰度资本的注重。

社区提问2:跟着ETH逐渐迁移至ETH2.0,不远的未来,会有大宗的显卡算力被释放。请问Core Dev Team有何方案应用好这部分算力,以晋升ETC收集的强壮性?

Jake:The community 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:社区不停有议论算力的迁移。阵势部人都认为ETH转向PoS后ETC可以取得许众算力支撑。终究上我们不应当说怎样应用这些算力去使收集强壮,越众的算力支撑这件事本身便是帮帮晋升收集的强壮的。(关于PoW收集来说,越众的算力本身就代外越平安)。这是我们的目标,也是我们做相似Atlantis这种升级的初志。

社区提问3:ETC 上的DApp有哪些明星项目呢?

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举措孵化器修立以后,越来越众的DApps挑选ETC举措开辟平台。方才完毕的第一轮项目孵化中,我看到了许众幽默的项目。比如说Button Wallet这个DApp,联合了Telegram和钱包的功用。这个项目最初设立时博得了包罗ETH旧金山、ETH丹佛、ETH新加波及ETH巴黎等黑客马拉松奖项。值得一提的是最终他们挑选了ETC上举行开辟。另有许众像Vrex Lab(AR资产墟市)、Slips(游戏直播挑衅平台)、StatWig(物流办理系统)等都是很酷的项目。我认为大师都应当体恤一下ETC Labs挑选孵化的项目,终究它们都是从上百个项目中脱颖而出的。

社区提问4:念要问下有些大的资本比较看好etc,可是许众散户并不看好,这是什么启事呢?

Anthony Luo 答:确实我也社区内听到过少许散户不看好的声响,但这也是无可厚非的。这部分散户并不是不看好ETC未来的代价晋升,而是他们寻求的是短期的收益。ETC不像少许高控盘的其他项目,不行够不停短期爆发。ETC是PoW挖矿的去中心化项目,只要靠技能开展、运用添加等少许方法一步一步做到代价晋升。以是许众资本及少许注重代价投资及区块链实质的投资者,照旧很看好ETC的。

社区提问5:ETC的github上的forkstar数目都不是许众,生动度仿佛也不高(除了etclabs孵化的项目外)。ETC的荒凉是平常状况吗?

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 community is active.

Anthony Luo 翻译:ETC有许众开辟团队,每个团队以致阵势部项目都有独立的代码库。我们一般相对应的代码库更新实质,再通通完毕后再同步到ETC的代码库。这便是为什么看上去ETC的代码更新数目显得并未几。终究上越来越众像我如许的开辟者正到场ETC,通通社区实是很生动的。

社区提问6:请问嘉宾,ETC将怎样去面临51%的收集攻击?

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 community is always working on increasing the hash rate, which can avoid the attack.

Anthony Luo翻译:ETC Labs Core年头爆发51%攻击后曾经开辟了一套攻击监控顺序,可以攻击发动时取得及时预警。我们将告诉各节点大幅晋升商业确认数,如许可以最洪流平的妨碍攻击,避免攻击者赚钱。当然社区也不停努力于晋升ETC收集的全体算力,当攻击资本过高时也可以从本源上避免攻击的可以。
