NEO理事会2-3月月报

有些社区成员问我们为什么没有发布二月的月报。简要回答一下,一月月报因DevCon的举办未能准时发布,紧接着就迎来了春节,放了将近两周的假。尽管我很确信NEO社区期待我们能汇报一下每位团队成员的假期生活,但我们更希望他们能通过自己的社交媒体自由发布。因为二月放假回来只剩下10天左右,所以我们决定将二月与三月的报告汇总成一篇篇幅较长的报告,而不是单独写一篇2月月报(也不失为一个选择)。

There have been a few community members asking where the monthly report for February went. To put it shortly; January report was released late because of DevCon (released Feb 6th), and shortly thereafter we entered the Chinese New Year with close to two weeks holidays. While I am sure that the NEO community would love to see a report of each team member's holiday, we will give them the freedom to post that through their own channels. Instead of writing a report for roughly 10 days' work (which also were an option), we summarize February and March in a longer report now instead.

首先,我们骄傲地宣布由微软中国协办的第一届NEO开发者大赛圆满结束。大赛历时5个月,共计约500余人报名,大约50个项目通过了质量初审,现阶段我们正在测试最后16个项目,我们将另行公告获奖项目。

First of all, we proudly announce the end of the first NEO Dev Competition, co-organized with Microsoft China. The competition ran for 5 months, with close to 500 project sign-ups. Around 50 projects passed the initial quality check and were all worthy of a prize. We are now testing the final 16 projects. You can expect a separate announcement with the winners.

我们还确定了NEO资助者回馈计划的回馈记录和金额计算结果,在撰稿时已经完成了批量发送,仅有一些申领人系统未能自动处理,因此我们进行了手动处理。发布本稿时大家应该都已经收到了回馈,如果有特殊情况的话,可能会延迟1-2天。我们预计转账会耗时2-4天,因此可能会发生一些延迟。

We have also finalized the records and calculations for NEO Sponsor Giveback Plan and have already completed a bulk send. There are some claimers which could not be processed automatically; these will be sent manually. The giveback should already have been received at the time of publishing, or in worst case, within 1-2 days. We expect that the sending itself will take 2-4 days, which is why some delay could potentially occur.

CoZ和KPN在测试链上测试共识节点已足足两个月。这期间完全做到了对节点运行的即时升级管理。同时,分布式资本的节点管理还处于早期阶段,他们已经完成了初始工作,之后由于要实现节点去中心化,他们仍然还有很多工作要做。3月初,主网由于P2P网络的问题造成了出块延迟,经过2.7.3和2.7.4两个版本的升级工作下,主网现在出块稳定。值得重申的是,NEO链上的数据不会因为偶然的出块问题而改变从而影响网络的运行。我们还根据主网运行中的数据统计中发现,在中国,当互联网流量处于高峰时段时,某些共识节点的延迟时间会显着增加,这里ISP服务器是其延迟的根本原因。这影响了节点的速度,我们计划将受到影响的共识节点升级到更快的ISP服务商那里。为了将来能降低共识节点的延迟,在那些共识节点完成上述升级(更快的ISP服务商)之后,Coz和KPN的共识节点计划将挂到主网上去。

CoZ and KPN has now been running consensus nodes on TestNet for two full months, managing 100% uptime and smooth node upgrades on short term notifications. Fenbushi Capital is at an earlier stage; they had their initial node set up but need to relocate it because of decentralization aspect. The MainNet experienced delayed blocks during beginning of March due to P2P issues; optimizations have been implemented in v2.7.3 and v2.7.4, and MainNet block times are now stable again. It is worth to repeat that NEO has 100% finality, so any occasional slow block does not affect the integrity of the network. Running statistics, we have also found significant latency increase to some of the consensus nodes during Internet traffic peak hours in China, and we have traced the root cause to the ISP servers. As this may affect consensus messages, we now plan to move affected consensus nodes to faster ISP's. To mitigate risk for future consensus message latencies, CoZ and KPN are scheduled to be voted in on MainNet after the move of these consensus nodes is complete.

随着NEP-5代币发行数量的增多,交易所向我方提出的技术支持需求也越来越多。因此,技术支持仍占了大量的开发时间,同时我们还发布了针对使用CLI 2.7.1及更高版本的交易所开发者的新文档。文档参见http://docs.neo.org/zh-cn/exchange/v2.7.1.html。

With more and more NEP-5 tokens released, we have gotten an increasing number of technical support requests from exchanges. Thus, much of our development time in February still went to technical support, as well as releasing new documentation for exchange developers using CLI v2.7.1 and above. The documentation can be found on http://docs.neo.org/en-us/exchange/v2.7.1.html.

二月,我们还参加了两次黑客松活动——START Hack和HackCU,这是NEO参加的头两次黑客松活动。Polychain最终在START Hack上赢得了NEO挑战,在NEO上部署了智能合约,实现资金稳定发放,使慈善捐款更加可信可靠。他们不但赢得了NEO挑战,而且赢得了START Hack所有挑战的总奖项。感谢Charlie Revett代表NEO和CoZ参加START Hack。项目信息参见https://github.com/louismerlin/neo-caritas 。

In February, we also participated in the first two hackathons for NEO; START Hack and HackCU. Polychain ended up winning the NEO challenge at START Hack, with a smart contract on NEO to make charity donations more trustworthy and reliable with stable release of funds. Not only did they win the NEO challenge, but they also ended up winning the overall prize among all challenges at START Hack. A big thank you to Charlie Revett for representing NEO and CoZ at START Hack. The project can be found here:https://github.com/louismerlin/neo-caritas

另外一个赢得HackCU挑战的慈善项目是NeoCharity,该项目可以给所有已接收的代币做上标记,并查询谁曾使用标记的账户进行了交易。FixitChain赢得了HackCU一等奖与最佳初学者黑客奖(Best Beginner Hack Prize),他们的方案旨在通过存储部分ID和修复历史记录的方式来减少浪费,这样就可以找到包含可靠使用历史记录的备用件来进行修复,而非丢弃。此外感谢Tyler B. Adam代表NEO和CoZ参加HackCU。HackCU提交的项目信息参见 https://hackcu4.devpost.com/submissions/search?utf8=%E2%9C%93&prize_filter%5Bprizes%5D%5B%5D=21104

Another charity project won the HackCU challenge: NeoCharity, which can earmark all received tokens and query to see who has transacted with a tagged account. FixItChain won the HackCU 1st Prize and Best Beginner Hack Prize. Their solution aim to reduce waste by storing part IDs and their repair histories, so that replacement parts with trustworthy usage history can be found to repair devices instead of throwing them away. Another big thank you to Tyler B. Adams for representing NEO and CoZ at HackCU. All the HackCU submissions can be found here:
https://hackcu4.devpost.com/submissions/search?utf8=%E2%9C%93&prize_filter%5Bprizes%5D%5B%5D=21104

两次黑客松的获奖者都获得了500GAS的奖金,他们可以利用这笔奖金将项目部署在主网上,也可以继续资助项目的开发。

The winners of both Hackathons received 500 GAS as prize, which would allow them to either deploy their project on MainNet or to continue fund the development of their projects.

3月11日,NEO携手Blockcamp在台北共同举办了首届solo黑客松,这次黑客松从早晨一直持续到了深夜,开发者编程活动与NEO项目见面会在同一个地方进行。NEOspace获得了一等奖,它们发布了一个基于时间租赁办公空间的智能合约,二等奖得主为Medchain,是一个患者数据管理项目,Neogenesis和Oblip分别揽获了三等奖和四等奖。再次向所有在场的CoZ开发者致谢,感谢他们让本次活动成为值得纪念的一刻。

NEO also held our first ever solo Hackathon in Taipei on March 11th, in collaboration with Blockcamp. The hackathon was running from the morning until late evening, with developers coding while NEO projects had meetup at the same venue. NEOspace ended up claiming the first prize with a Smart Contract to lease office space on per time basis. Second prize was won by Medchain, a project to manage patient data. Neogenesis and Oblip won third and fourth prize. Again, a big thank you to all the CoZ developers who were on site to make this an event to remember.

过去这两个月还有两位全职员工加入了NEO团队的运营,他们是Miki Hayama和孙丰达。

We would also like to introduce two new full-time team members joining NEO operations; Miki Hayama and Sun FengDa.

Miki Hayama担任Head of Japan Operations,她曾在伦敦工作生活了十年,负责汽车行业的海外市场运营,曾去过15个国家,她的工作是负责各国团队的协调沟通,因此自打区块链开始引起关注后,她自然也就成为了区块链行业口译员。她是第一位NEO全职海外员工,负责日本运营,包括社区建设以及深度市场活动。Miki现在常驻东京。

Miki Hayama has joined as Head of Japan Operations. Spending a decade in London and being in charge of overseas Marketing in the automobile industry with experience from 15 countries, Miki has been engaged in bridging the parties across the countries which naturally brought her to be an interpreter for top managers within the blockchain industry. She became the first full time team member out of China for NEO covering Japan Operations including community building and all activities for the Japanese market. Miki is based in Tokyo.

孙丰达是NEO的资深研究员,自2017年6月以来她一直致力于跨链技术研究,现已正式成为NEO上海团队的全职员工。她在洛桑联邦理工大学获得微电子与微系统博士学位,在洛桑高等商学院获得金融硕士学位。孙丰达是半导体行业的一位成功的研发工程师,加入NEO前曾在日内瓦负责外汇风险管理。她持有FRM证书。

Sun Fengda is a senior researcher at NEO. She has been conducting research on interchain technologies for NEO Council since June 2017 and has now officially joined NEO's Shanghai team full-time. She holds a PhD degree in Microelectronics and Microsystems from École Polytechnique Fédérale de Lausanne and a Master degree in Finance from HEC Lausanne. Sun Fengda has been a successful R&D engineer in the semiconductor industry and has worked with foreign exchange risk management in Geneva before joining NEO. She is also an FRM holder.
