[米其林台北指南] 牛肉麵・劉山東

DSC_6446.JPG

半年前介紹了一間台北米其林美食:[Michelin Guide Taipei] [Bib Gourmand] Mao Yuan - the Taiwanese Cuisine 🍴🍷 [米其林台北指南] 台菜之巔・茂園餐廳

這次,我們又去了一間米其林推薦美食,不過,不算餐廳,是間小吃店!這是米其林必比登系列,不是正式星等系列的。

劉山東牛肉麵

哇,聽起來就很正宗哪!要知道台灣牛肉麵是源自於山東麵食在地化的,這家店名有山東,不知道是不是創始老闆的名字…. 管他的,好吃就好!^^

店非常普通一般,位於台北車站商圈的巷子內,毫不起眼。

店內座位不多,頂多二十來個位子,很容易就客滿。

桌上的調味佐料等,是很重要滴!酸菜,有!辣椒呢…. 嗯,有辣油,然後,黑黑的那是辣豆瓣,不會很辣的。

DSC_6440.JPG

拿了三盤小菜,每盤都是20台幣,蠻便宜的。小菜都是很簡單樸素的,算是不錯吃的。

來了來了!據說是店內招牌的~~~ 清燉牛肉麵!!

看起來就是好吃樣,吃起來,嗯,確實是好吃的!!牛肉很嫩,毫無乾澀感。青蔥非常鮮甜,配上非常有滋味的清燉湯頭,很搭!這幾乎是我吃過最“不清淡“的清燉牛肉麵了!非常好吃!

真要挑剔的話,就是麵條口感我不是太喜歡,但是我後來聽到有人點細麵,才知道有細麵的選項… 想像中,如果這一碗是用細麵的話,我應該可以給他很高分數的!

分數高,但價錢還好,150元,以牛肉麵來說不算太貴,以米其林推薦來說,超級便宜!

吃完清燉,來一碗紅燒牛肉麵!!吃牛肉麵的人都知道,紅燒才是主流,是正宗~~ 因此,非常期待他們的紅燒,咦?端上來,感覺差異不大….

吃起來,….. 嗯,說真的,完全不懂。這一家怎麼清燉像紅燒,紅燒像清燉了呢?這是我吃過最搞不懂的紅燒牛肉麵,有紅燒味,但不重,若有似無,因此變得蠻怪的。當然,不能說是難吃,就是怪。不知道是這一碗出錯還是他們真的比較特別?

因此,我推薦到這裡,吃清燉牛肉麵就對啦!如果你喜歡細麵,就要指名一下!

DSC_6444.JPG

對於列入米其林必比登推薦,店家並不張揚,只有這小小一張公告而已~~

DSC_6447.JPG

據說,這家店常常被拿來跟林東芳牛肉麵比較,確實有其道理(關於林東芳,請見這一帖)。就我印象中,劉山東的清燉,如果用我想像中的細麵,應該略可跟林東芳一較長短~~

不過,既然我說了”略可”,你大概就知道,我比較偏好哪一家了~~

噢,好久沒去林東芳了,該找時間去吃一碗了!^^

想當年... 老人囈語

最近的情況讓我想到一年半前的情況,我把當時我的帖子找了出來…

When trending posts earn less than a hundred …

首頁的收入最高沒破百…. 當時以為應該是很低點了,沒想到現在更低了,呵呵~~ 當然,我知道狀況不一樣,這次,再過幾天,Voting power就會恢復,可能就會比較接近分叉前的日子了。

還有一點不同是,Steemit的首頁算法有變,以前是純粹按收入排,現在是金額與日期一起考慮,所以目前的首頁其實有很多文章是分叉前的….

我剛剛本來想找一找當時的分叉編號跟內容,但找不太完整(順便問問誰知道Steem在哪裡有歷屆分叉的內容與日期?官方與民間版本都可以),所以就算了…

以前很多規則,我慢慢都淡忘了,剛剛看到一個,覺得好懷舊喔!順便嘮嘮歷史,扮演好老人角色…. ^^

你知道,以前Steem的帖子收入,曾經分成兩段式:第一段,24小時內結算;第二段,24+小時到30天之內

聽起來很不錯吧!文章有機會賺更久的錢!一整個月都有機會喔!

那為何改掉呢?

基本上,原因就是,第二段時間在實際上幾乎沒用,很少人會在第二階段收到明顯的收入,有機會拿收入的,95%以上是在第一階段。

你或許會想,這是絕佳的自我點讚機會哪!Well,當時,不是線性獎勵,你自己點自己,效用很低,高額的收入都是集結點讚才出現的…. 所以,偷偷自我點讚是沒有動機的喔!

我自己有過一個慘痛經驗,當時我最高收入文章,那一次的大部頭收入落在第二段,看起來很激動,但要拿到手,得等上一個月,然後我越等越低,因為剛好幣價再跌,拿到手時,已經不到當時看到最高的一半了~~

分叉路

放了兩天假了,更精確的說是,被放兩天假了。這難得的空檔,我本來以為會更長,結果似乎漸漸要回到軌道了。

這次的分叉,確實遠比我想像的影響還要大。原本我以為,只要擔心自我點讚,以及點讚別人的時間點就好了,其他技術細節,跟我們這些技術麻瓜無關。結果我錯了,似乎這轉換的過程,確實出現了滿大的問題,官方也算是有表達歉意,只是似乎沒有達到大家認為應該的程度。

我不禁在想,這裡所謂的官方,到底是什麼意義?如果區塊鏈是去中心化的,那麼,我們有可能可以投票換一個官方嗎?仔細想一想,其實官方這個用詞,不是很正確。比較精確來說,Steemit Inc.以及他所屬的員工們,目前擁有此一區塊鏈系統很大一部分的代幣,因此使得他們成為,此系統的最大利益相關集體(當然這個集體也是隨時有可能變化的,例如員工去職等等)。

這使得他們在實質上,確實有動機表現出像是官方這個詞所代表的姿態 ,再加上他們算是創始團隊的延伸,這樣的結果造成了普遍大家都認為他們是“官方” 。

其實我對於所謂中心化,沒有絕對的意見。中心化其實在很多時候都需要的,甚至可以說,去中心化非常需要中心化,重點在於需要的層次,以及中心化得到合理授權的程序。

看到社區很多人在批評Steemit Inc.,我不禁在想:到底我們跟他們之間的關係,到底是怎麼樣的?如果現在還沒有辦法達到理想狀態的話,那麼所謂的理想狀態中,又該是什麼模樣呢?

我相信社區大部分的人都同意,這一次的硬分叉,並不能算是成功(當然我也不同意它失敗了)。 也就是說社區的共識是,HF20做的並不算太好,至少在轉換的過程不是。但是,似乎這個共識,並沒有辦法成為一種正式的宣告,而只能是一種”普遍的意見”….

或許我們還有很長一段路要走吧….

Republic Protocol (REN) Analysis and Valuation.

Hi investors, Dean (@deanliu) and FØx (@tradealert) are back and today we dive deep into the world of decentralized dark pools.

photo-1512094244022-4816e6e7d764.jpg

Executive Summary.

Republic Protocol is an open-source protocol for creating decentralized dark-pools built to trade large amounts of crypto-currency.

The project was co-founded in 2018 by Taiyang Zhang (currently CEO) and Loong Wang (currently CTO) and consists of 8 core developers and 2 community managers.

Sixty percent of a total supply of 1,000,000,000 of REN (ERC-20) tokens were put on sale for $0.5 USD/REN during a February 2018 public ICO which raised $34,400,000 USD. The project attracted a number of high-profile VC investors among them PolyChain, Huobi Capital and FBG Capital.

Like most ERC-20 tokens, REN has considerably under-performed in 2018 and the token is currently trading around $0.031 USD at x0.56 its ICO value.

Around 20% of the supply of REN is still owned by the project according to Etherscan.

Republic’s devs have been hard at work, ranking 5th place in the top 10 most active projects on Github in the past 6 months (right behind EOS) and 6th place over the past 12 months which is impressive for such a small team.

Before diving into Republic, it helps to understand how dark pools function in traditional markets.

Dark Pools in Traditional Markets.

Dark pools are private exchanges run by large institutions (typically investment banks) where financial assets (like stocks) can be traded privately.

Contrary to common belief, dark-pools are not anonymous exchanges since all market participants (buyers and sellers) have to comply to KYC and disclose their trades after they are concluded.

Unlike brick and mortar banks or NASDAQ exchanges, dark pools don’t have a physical location per se nor do they have a standard structure. Trades are usually arranged on the phone or via Skype and usually involve the 2 parties to the trade and a third-party (the broker) charged with facilitating the trade and moving the assets.

Because of their privacy, dark pools are an attractive option because they allow market participants to conduct large, strategic trades without alerting the general public and/or risking being front-run by their adversaries.

As a result, it is has been estimated that 14% of all equity is traded in dark pools in the US.

Unfortunately this privacy has comes at a cost. Dark pools have become the play-ground of high-frequency trading firms and the institutions running them (the dark-pools that is) have been accused of discriminating between their clients, prompting SEC to intervene and require more transparency and fairness.

Republic Protocol Dark Pools.

Republic Protocol distributed (but non-blockchain) architecture (1) gives it some unique features that could address many of the shortcomings of traditional dark-pools (2).

1. Distributed.

Republic Protocol consists of a base layer onto which decentralized dark pools can be built by anyone.

1_6qLA-WbmtpSS2mTnjVRPHQ.jpeg

Republic is not a blockchain but rather a “traditional” peer to peer communication protocol (similar to BitTorrent) which uses ERC-20 tokens (secured by the Ethereum blockchain) as secure bond for the nodes on the network.

Republic nodes (aptly called dark nodes) can be set up via a client. Each node requires a 100k REN bond to be registered and, at a total supply of REN of 1 billion tokens, there can only be a total of 10,000 nodes on the network.

Together, dark nodes provide a computational base layer that powers any dark pool built on the protocol. The role of dark nodes is to privately match buy/sell orders via a cryptographic technique called Shamir’s Secret Sharing.

Although only cryptocurrencies can be transacted on the protocol, these transactions are considerably varied and can either be between assets belonging to the same chain (i.e. between Ethereum ERC-20 tokens for example) or cross-chain (i.e. ETH to BTC) via a technique called atomic swap.

So far, ERC-20 tokens (including tokenized gold), ETH and BTC have been implemented and it’s likely tokenized fiat and stable-coins (such as Gemini’s crypto-dollar) will also be integrated in the future.

2. Fairness and Availability.

Being distributed and open source, the protocol allows for the creation of dark pools where:

  • the rules are transparent and fair;
  • hosted APIs are directly available to traders;
  • the protocol, unhindered by a blockchain architecture, can scale to a large number of transactions;
  • the network is secured by a decentralized, un-hackeable network of nodes;
  • crypto-currencies can be privately traded in large amounts without exposing sellers to slippage typical to centralized crypto exchanges.

The first such dark pool, RenEx has already been built by the core dev. team and is set to launch in the coming weeks.

1_9H5R73zX4M7Pu4L7VXcZNg.jpg

What’s more, the team has already secured a partnership with USA-based Wyre to ensure RenEx needs regarding liquidity and KYC/AML compliance.

“Wyre specializes in infrastructure to bridge the gap between traditional banking and digital assets. Pairing this expertise with RenEx will serve as an integral tool in Wyre’s OTC services, which to date have traded $3.5 billion in digital assets in-house and more than $750 million in bank-to-bank commercial FX payments. Working together, Republic Protocol and Wyre will help usher in a new era in dark pool trading, merging traditional financial infrastructure with the world of decentralized finance.”

Investment Thesis.

The investment proposition here consist in acquiring REN tokens that power the base layer of the protocol.

REN tokens are ERC-20 tokens spawned from an Ethereum smart contract. These tokens currently have two main use cases:

  • traders must stake some amount of REN to transact in dark pools, this prevent spamming attack from malicious actors;
  • staking 100k tokens allows anyone to become a dark node on the protocol’s layer 1 which powers the entirety of the ecosystem.

As the Republic network grows, it is to be expected that the demand for REN to stake as trader bond could put some upward pressure on the price but this requirement could also end up being eliminated as the technology matures and alternative ways to prevent spamming are discovered .

Provided they keep up with the network requirement regarding speed an bandwidth (which are expected to grow as the network develops) Dark Node operators however will always be rewarded a fraction of the total amount of every trade they discover over the entirety of the network including all the dark pools built on top of the protocol.

Considering the scope of the work done by dark nodes, it’s been (very optimistically) estimated that a single node could earn as much as $300k USD in a single year by 2022 (bull case scenario):

0_FxFuxbubCnIWVHaG.png

Or around $60k USD / year (base case scenario):

0_vN3-8Kk5Q3p8Z0Ur.png
from Republic Protocol: Analysis and Valuation by James Todaro, Joseph Todaro and John Todaro

Unfortunately, these projections were partly incorrect:

  • the maximum number of dark nodes has been set at 10k (1B total supply / 100k = maximum number of dark nodes) though the actual number of nodes could find equilibrium way short of 10k, provided REN tokens retain a utility beside being used as bonds.
  • the fee paid to a dark node after matching a transaction on RenEx will initially be set at 0.32%: (0.2% maker fee + 0.2% taker fee = 0.4% > 80% of 0.4% goes to the nodes and 20% to the liquidity incentive program = 0.32%).

Now, ROI projections are a delicate endeavor (variables change) and should err on the side of caution not to disappoint investors.

With that in mind, we’ll start from the 2022 ROI divided by 3 to take into account the compression of margins, the increasing hosting costs, the maximum number of nodes at 10k and the 0.32% initial fee which is likely to diminish as competition with other dark pools increases, we expect a ROI of:

  • approximately $20k/year (base case) + alpha (appreciation of 100k REN bond)
  • approximately $100k/year (best case) + alpha (appreciation of 100k REN bond)

For an initial investment of $3100 USD / dark node.

Disclaimer: This is not investment advice, investors should always do their own diligence.

Other Risks.

There are a great deal of risks that must be taken into account before investing in the project.

1. Competition & Liquidity.

Competition will come from both traditional crypto OTC desks (Kraken, Gemini, Coinbase) and possibly from other decentralized exchanges (DEX) project such as 0x or Airswap which could (though haven’t yet) technically evolve to offer dark pool services in the future.

As it stands, Republic benefits from a considerable technological head start over DEXs in the sense that their first dark pool is about to go live. Besides, the project’s non-blockchain architecture allow for scaling to a large number of transactions whereas DEXs still have to find ways around the limitations of slow blockchain databases.

However, Republic’s advantage is much less evident against OTC desks run by established crypto exchanges (like Kraken’s) which dispose of a much larger network, reputation and access to liquidity than RenEx.

Ultimately, the project could fail if:

  • developers show no interest in building dark pools on the protocol.
  • other exchanges offer more competitive trading fees and liquidity.

2. Robustness.

Even though the technology has shown great promises on the Ethereum testnet it is still unproven in an adversarial environment and it might be quite some time before financial service providers become comfortable trusting the network (or obtain legal clearance) with millions in crypto-currencies.

0_d0uLedEgqsT5OjPC.jpg

As always, the first users of this technology are expected to be smaller, entrepreneurial financial players who will likely use the protocol for small transactions first before scaling up.

Ultimately, the project could fail if:

  • it proves fragile and buggy in an adversarial environment, leading to loses for users of the protocol.

However, if the technology developed by Republic shows resilience in the wild, the project could rapidly expand its pool of liquidity and even companies like Coinbase or Bitfinex (which have a strong decentralized vision ) could possibly harness the technology to power their own ecosystem.

Conclusion.

Republic Protocol offer a pertinent use case for a hybrid technology incorporating an ERC-20 token with a traditional distributed system.

Not encumbered by a blockchain architecture and developed by a dedicated team, the technology has the potential to scale fast and to bring a much needed dark pool infrastructure to the blockchain ecosystem.

However, the project’s ultimate success will depend on its ability to be secure, to attract developers and to offer a competitive trading and liquidity ecosystem to its users.

Invest at your own risks.

從大屁屁到阿屁屁的

peach-2721852_640.jpg

昨天分享了一篇報導:從Steem鏈停擺,到O哥出塊,那一篇報導,其中提到咱船長的一句話:

For the Steem blockchain, that’s 400 applications, according to Scott.
這裡說的自然是在Steem區塊鏈上運行的許多應用項目了…. 你我皆知,400是個非常過度高估的數字了… 我想,Ned的根據應該是這個很棒的網站:

https://steemprojects.com/

網站開宗明義說了:”Steem Projects is a directory of 441 apps, sites and tools

所以,Apps、網站以及小工具等等,都算上去了。但無論如何,沒事去看看這網站,還是挺能激勵Steem持有者的信心的!

至少,Ned沒說,Steem有400多個dApp

想到這裡,我就想到我長久以來的一個疑惑:到底dApp的定義是什麼?怎麼樣才能算是dApp呢?

於是,我稍微找了一下,發現,其實目前還沒有很明確很一致的定義。但似乎蠻多人引用David Johnston的定義:

只有当满足以下所有条件时,一个应用才可以称之为DAPP。

  • 应用必须完全开源、自治并且没有一个实体控制着该应用的大部分代币(Token)。该应用必须能够根据市场的反馈及技术要求进行升级,但是升级必须由应用的用户达成共识之后才可以进行;
  • 应用的数据必须加密后存储在公开的区块链上;
  • 应用必须拥有代币机制(可以使用已存在的代币或者新发行一种内置代币),矿工或者应用维护节点需要得到代币奖励;
  • 应用代币的产生必须依据标准的加密算法,有价值的节点可以根据该算法获取应用的代币奖励。

來源:https://zhuanlan.zhihu.com/p/31578996

這個定義,我認為蠻嚴格的,一般大家說的dApp,似乎多半不能滿足上面全部條件。

也有人說,dApp其實本質就是智能合約。這麼簡單的說法,似乎有是有點道理,但似乎又不是很完整。不過,如果我們大致採用這個說法的話,那麼,可以說Steem區塊鏈上,根本沒辦法有dApp,因為這鏈並不支持智能合約運行。將來的SMT似乎也不是為了這個目的。

不過,就算Steem沒有dApp概念的Apps,說真的那又如何?重點還是在於區塊鏈跟要解決問題之間的關聯,至少,某種程度的decentralized的Apps是肯定有的,否則用Steem鏈不就白用了?

題外話,關於Steem是否需要智能合約,我剛剛找到一篇很精彩的討論:Does STEEM need Smart Contracts?,除了主文之外,還要去看留言的 @andrarchy跟 @yabapmatt

回到dApp的討論,看來,這概念或許可以很明確,但是App到(嚴格定義的)dApp之間,應該是一個很廣闊的空間:或許是App資料儲存在區塊鏈上而已,或許是App的幣使用加密貨幣而已….

想到這邊,我認為或許一個App-d(阿屁屁的)的概念會比dApp(大屁屁)好:也就是說,這類App,都有d (decentralization) 的成分,但還算不上是最嚴格定義的dApp

這樣的話,咱Steem那400多個玩意兒,全部都可以叫做App-d(阿屁屁的)啦!^_^ 開心不開心!?
