Wasm

Most time working with Rust is a pleasure — great ecosystem, excellent tooling. However, dark places in the world drive a developer into the madness. Recently I had such a journey I would like to share with you. Context To talk about the problem, I have to start with setting up…

This post is a translation of this korean post. It has been such a long time since I published the introductory post. Probably not, but I’m sorry if anyone has waited for my next post.😓 Table of Contents Overview Interact between JS and C++ Others about WASM Others(camera, C++ code) Closing 1.

配上 Docker 達至無痛編譯。 — TinyGo 是一款可以直接把 Go 軟體編譯成體積更小的編譯器，通常會使用在一些崁入式裝置（如 Arduino、Raspberry Pi 等）或者是今天想分享的 Wasm (WebAssembly)。 與 Go 的分別 其實在 Go 中原生已經支援編譯 Wasm，但是由於本身體積比較大，如果在前端上的載入速度會比較慢，使用了 TinyGo 所編譯後的 Wasm 檔案大小從 3.8 Mb 下降至了 2 Mb（接近 50%），效果十分明顯。 目前 TinyGo 還是會有一些不支援的 Go 原生 package，另外我在使用上，也遇到了一些 math/big 上的支援問題，因此需要特別留意。 編譯 Wasm 確保已完成安裝 Go 安裝 TinyGo 執行 tinygo build -o main.wasm -target=wasm ./main.go 錯誤排除（已更新）

Summry While checking the Astar hub for the first time in a while, I noticed an article about OpenBrush. I recently refocused on wasm’s smart contracts. Then, I found “metis” and tried to implement it, but it didn’t seem to support the latest version of ink !, so I was sad…

This article discusses WebAssembly a.k.a Wasm runtimes. In particular, how a WebAssembly runtime can provide additional resources and features. In addition, we introduce a new technology whereby users can create their own WebAssembly runtime plugins. What are WebAssembly (Wasm) runtimes? WebAssembly’s execution behaviour is defined in terms of an abstract machine that models the program…

When it comes to smart contracts there are two competing technologies. The original EVM smart contracts enjoy wide support and adoption, while WebAssembly is an emerging standard that promises higher performance and has great support in the Polkadot space. In this article, we analyze and compare both technologies. — At Pendulum we strive to provide the best experience for our ecosystem developers. In this comparison, we will focus on performance. Higher performance means more transactions per second, i.e., higher scalability. Most smart contracts are rather simple and only require a few computational resources. However, as more advanced DeFi applications…

ในเมื่อใช้ TypeScript เขียนเว็บอยู่แล้ว เราก็ใช้ TypeScript ทำ WASM ต่อไปสิ — พอดีไปเจอว่ามีคนทำ Compiler ที่สามารถแปลง TypeScript ไปเป็น WebAssembly ได้ นั่นคือ AssemblyScript ทันทีที่รู้ว่ามันมีตัวตน ว้าวมากนะ เพราะเราสามารถใช้ TypeScript ทำเว็บ และ WASM ด้วยภาษาเดียว WASM (WebAssembly) คืออะไร WebAssembly คือ ภาษา Assembly ที่ทำงานต่อกับ Web Technology ผ่านตัว Web browser นั่นเอง เมื่อพูดถึงตัว Assembly เอง หลัก ๆ มันก็คือประสิทธิภาพนี่แหละ มันสามารถ ทำอะไรหลาย ๆ อย่าง ที่ JavaScript ทำไม่ได้ หรือทำได้ยาก

Introduction When developers get tools they like, they tend to be more productive. Extensibility in a language of choice provides the convenience of extensibility without learning a new language. WebAssembly runtime executes bytecode, generated by compiling code written in high level languages — javascript, C, C++, Python, Rust or Golang. We…
