Taiwanese hacker team HITCON scored the second in world’s most prestigious hacking competition DEF CON Capture the Flag in Las Vegas. A core team member is a software developer at Second State Inc. In the just-concluded DEF CON 27 CTF hacking contest, after three days and two nights of “competition”, HITCON & BFKinesiS team from Taiwan defeated Team Tea deliverses and A*0*E from Tencent and won the runner-up. The core member of the HITCON team is also a software engineers at Second State.
Libra 在国会听证后，该何去何从？ 在Libra 开发与在以太坊上开发有什么不同？ ERC 20 token 能否在Libra 上做交互？ 如何快速入手DApp 开发？ 8月3日，
With Libra being scrutinized, if not attacked, at Congressional hearing, where is the anticipated ambitious global stable coin is heading towards? What is the difference between the programming on Libra and Ethereum? Can ERC 20 token interact with Libra? How to get started with DApp programming in a few minutes? These are discussed in detail at the tech workshop “Libra Smart Contract Deep Dive” held in Beijing, China, on August 3rd.
This article is the third and final part of the “Libra First impressions” series. In the previous two articles, we explored the technical implications of the Libra project and the internal processing and execution of Libra Client and Validator. Libra First Impressions Part 2: Deep dive with a Libra transaction Libra First Impressions Part 1: Smart Contracts are not created equal Write your token module In this article, we will show you how to use Move IR to write a simple token module.
本文是 「Libra 深度剖析」系列文章的第 3 篇，也是最后一篇。在之前的两篇文章，我们分别探讨了 Libra 项目的技术意义以及 Libra Client 与 Validator 内部处理与执行交易。
Credits: FairPlay is developed by Second State, an open source enterprise smart contract platform, and deployed on the CyberMiles public blockchain. What is FairPlay FairPlay uses smart contracts to conduct automated prize draws that are fair and transparent. It allows anyone to create and participate in product giveaways and e-commerce marketing campaigns. Since its launch, FairPlay has routinely reached a DAU (Daily Active Users) of 1000 (according to Google Analytics), with each giveaway receiving hundreds of on-chain transactions, making it one of the most popular DApps of all public blockchains.
This article articulates the importance of putting decentralized, blockchain, applications (DApps) into the hands of mobile technology users. More specifically, the importance of providing real-time blockchain data to decentralized applications (DApps) which run on mobile devices. This is the first of many articles. This particular article provides an overview of the smart contract search engine architecture and then provides specific code examples for querying the search engine and API. Future articles will explain the inner workings of the product.
This is the second article in a 3-article series on the technology behind Libra. The first article is an overview of Libra and its smart contract programming language Move. In this piece, we will deep dive into the technology stack and use the source code to show what happens behind the scene when users interact with Libra. Taking “getting Libra coins” as an example, let’s examine how Libra Client and Validator Faucet process and run a transaction.
在上一篇文章中，我们初步探索了 Libra & Move 语言 。在这篇文章中，我们将探讨使用者如何跟 Libra 进行互动。本文以向 Libra 水龙头(Faucet)索取 Libra 币为例子，解
