最近在写 #cairo#starknet 智能合约 开发 晚点分享一下经验 先开个贴 😄
#StarkNet@StarkWareLtd 公司下的👊产品之一,一个permissionless layer2, 可以理解为 @optimismPBC 或者 @arbitrum_cn 但当然用的是 ZK-Rollup技术。ZK-Rollup当然fundamentally要比Optimistic-Rollup好很多。加上VC的疯狂青睐 所以这两周在研究 @StarkWareLtd
为了更好的实现 STARK 算法 @StarkWareLtd 自己弄了一套语言框架 叫做 #Cairo 语法比较类似 #Python ,据说目前后端使用Python实现的。当然 #Cario 有很多坑 比如 felt 类型 等。这些特性都是为了更好的计算ZERO-Konwledge Proof。但感觉要比 solidity 更好用

[MINI-THREAD 🧵 ] Et si on apprenait #starknet ensemble? Image
[⚠️ DISCLAIMER ⚠️] J'ai vu dans ma TL des gens en parler, je me suis dit qu'il serait intéressant de découvrir l'écosystème ET de rédiger un thread en parallèle.

Il se peut que les informations récoltés soient érronés / mal comprise. Je compte sur les vaillants pour me corriger!
Alors, déjà comment j'en suis arrivé à vouloir voir #starknet ?
C'est assez simple, des gens comme @0xAurelou en parle constamment 👀
Et je me suis dit que vu que je connais rien à l'écosystème et aux langages utilisés ça ferait un beau challenge !

It is day 46 of writer and activist #AlaaAbdelFattah's open hunger strike in Tora prison in #Cairo. His health has deteriorated to dangerous levels. When his mother Laila Soueif last visited him, she reported that Alaa had lost a lot of weight and was feeling weak.

#Egypt
Abdel Fattah's family fears for his life, as he enters a delicate phase of his hunger strike. His body will start using its own fat and tissues to survive, including the heart, which may have permanent and even fatal effects.
./2
Alaa began the strike to protest his life conditions in solitary confinement. His family said he is being deprived of basic rights and subjected to repeated torture, beatings and humiliation.

Yemenia Airways media official  Salam Jabari said in a press statement that the company is awaiting permits from the Saudi-led coalition to launch

commercial flights.
He added that so far no permits have been obtained.

“The delay in operation was not a technical issue, but a political one caused by the coalition. The United Nations should press the coalition to grant permits for flights,” he said.

Jabari predicted
that commercial flights to Sana’a airport would not be operational in the near future unless the United Nations exerted pressure on the coalition as it is the sponsor of the truce.

He stressed the readiness of Yemenia to operate two flights a day to Sana’a from Amman and

1/ Yesterday, I highlighted zkSync.

So it only makes sense that I do the same for @StarkWareLtd and their #Ethereum rollup solutions #L222 #StarkEx and #StarkNet

Another deep-dive thread into one of the projects changing the scaling world 🧵...
2/ First, again, some high-level Pros and Cons
Pros with using Starkware products

- Increased TPS compared to ORs (~9,000+ TPS on Ropsten testnet)
- Faster withdrawals (no challenge period), enabling better capital efficiency and liquidity
- #Validiums (discussed below)
3/ Cons

- Developer UX and porting of dApps from L1 to #L2 is more challenging than OR options
- #Cairo language less popular among developers = less talent pool to build on Starkware
- With Starkware's #Validium option, there's a technical challenge in solving DA problem.

Do you know the story of #coffee?

Sure you get it from Starbucks or grind it at home but its story was not as simple as farm to pot

The story involves dancing goats, Fatwa, babtization, kings, revolutions, patriotism, Beethoven

Coffee has a rich & troubling history

☕️ Thread
1/ 1st, the legend:

Legend has it that an #Ethiopian goat herder named Kaldi witnessed his goats gamboling after eating coffee shrub’s red fruit. Perplexed, Kaldi tried the fruit himself and realized the same effect on him. A monk witnessed it & took some of the fruit with him.
2/ Now, the history:

The coffee plant and fruit has been used for 1000s of years but it wasn’t until the 13 century when the beans were roasted, which sky rocketed its popularity. Coffee originated in Ethiopia but it was across the Red Sea, in #Yemen, it was first cultivated.

أسرة أمريكية تبدأ رحلتها إلى القاهرة، هذا الأسبوع، وهي الرحلة التي تم جمع تكاليفها من خلال بيع شرائح اللحم بالجبن لتحقيق حلم الأم

متابعة.. al-a.in/tssXXoQ
"أنتظر رؤية ابتسامتها عندما ترى #الأهرامات لأول مرة، وآمل أن توفر لنا هذه العطلة ذكريات تبقى معنا إلى الأبد".. هكذا قال الشاب الأمريكي، داستن فيتال، الذي يقوم ببيع شرائح اللحم بالجبن من أجل جمع تكاليف رحلة لوالدته المريضة بالسرطان لـ #مصر

#Pyramids #Egypt #VisitEgypt Image
وكتب فيتال مقالا نُشر في مجلة "#نيوزويك" الأمريكية، قال فيه إن والدته قد نشأت في أسرة منخفضة الدخل، ولم يكن لديها الكثير من المال عندما تزوجت، وظلت تعمل طوال حياتها حتى إنها لم تكن تحصل على أي إجازات

On Saturday 3rd April 2021, #Egypt put on a lavish parade in the capital #Cairo to locate 22 mummies from the Egyptian Museum to the National Museum of Egyptian Civilisation.
2/
Images of the slick 4 mile parade and an equally carefully choreographed opening ceremony were broadcast live on state television, to rousing music and a 21-gun salute.
3/
The procession, dubbed the "Pharaohs' Golden Parade", of 18 kings and 4 queens travelled in order, oldest first - each aboard a separate vehicle decorated in ancient Egyptian style.

The carriages were fitted with shock absorbers for the trip, to ensure they had a smooth ride

#Pakistan-#Egypt FM-level talks.

Issues: #Libya-#Yemen-#Gulf-#Ethiopia-#Gaza-#Kashmir.

Robust military ties but overall weak political exchanges between #Cairo & #Islamabad.

Yet @ImranKhanPTI-@AlsisiOfficial governments have recently been in contact to upgrade cooperation.
#Pakistan & #Egypt revive stalled ties. Pakistani foreign minister meets President Al-Sisi. Agreement to launch high-level political consultations next month. #PakMilitary will participate in drills in Egypt in summer. /2

#Pakistan & #Egypt are often considered two players with imp roles in ensuring #Gulf stability, along regional & intl partners; can help in Mideast peace, in Yemen, in fighting extremism & extremist groups. These are recurring themes in discussions:

1/ Seems #Haftar has pulled off a last minute upset after finding himself being cornered by his allies locally and internationally.
While his allies find themselves shuffling to make sense of yesterday’s developments, Haftar is positioning himself as sole negotiator of the east.
2/ For #Haftar to successfully achieve this goal, he will need to carry out a hard reset as his advisors are now blamed for failing to secure a new executive consisting of their allies.

#Agila is facing heavy criticism both socially and politically in Eastern #Libya.
3/ #Agila was warned by constituents to avoid a deal with #Bashagha and to have a back up plan that allows a ‘socially’ acceptable candidate take his place such as #Baraghthee of #AlWafi (in that order).

The competition for social credit is now between #Haftar & #AlMnefi.

#Egyptian regime crackdown continues against human rights group @EIPR after staff met with Western ambassadors in #Cairo.

Security Forces arrested executive director Gasser Abdel-Razek from his home on Thursday, the 3rd employee arrested this week
google.com/amp/s/amp.cnn.…
I’ve known Gasser since the 1990s when I was a Reuters correspondent in Cairo who would often call him at the Hisham Mubarak Centre to comment on cases.

He is one of the most sincere and big-hearted activists I have ever met. He truly loves Egypt and the fight for its liberation
Gasser’s detention comes after Egyptian security forces detained two other EIPR employees:

Karim Ennarah, the head of the group's criminal justice department, was arrested Wednesday while spending vacation in Dahab, Sinai, His whereabouts and the charges he faces are unknown.

So students of the #Egyptian Police Academy can parade shirtless for Sisi but the regime arrests women - fully dressed - for selfies and videos on TikTok? h/t @almudenariverob Shirtless men
The more clothes #Egyptian men remove, the more they are celebrated for virility - from the police academy to celebrities
