Blockchain

新聞報導以至歷史的杜撰，不能單靠單一組織，否則必然會出現篡改歷史，甚至焚書坑儒的情況。無大台管理的區塊鏈，正好擔當不可竄改的史書，配合星際文件系統（IPFS），讓每個人共同參與紀錄歷史，守護真相。

本工作坊介紹無大台出版的要點，然後與聽眾一起，弄髒雙手，嘗試實際操作。

Blockchain is an emerging industry moving at a lightning pace, even after 10 years since bitcoin was born. It shares a similar philosophy with open-source culture and tried to bring these values into the financial area. This sharing is going to cover why open-source plays an important role in blockchain business as well as how consensus in the community affects the whole industry.

The Linux Foundation launched the Civil Infrastructure Platform (CIP) project to develop base layer, open source industrial-grade software for civil infrastructure projects, the CIP supports electrical and power grids, railway, shipping, and transportation systems, among other applications that are imperative to human life. Currently, there're several active workgroups in this project, such as Linux kernel, real-time, testing, security, and software update.

We are building a general digital content registry called International Standard Content Number (ISCN) which is using the Cosmos-based blockchain to validate and store the registry itself. However, it is not intuitive and easy to use for users to query the registry directly from the blockchain, and now we are riding on the powerful distributed file system InterPlanetary File System (IPFS) to make some plugins to help to distribute the registries globally decentrally and distributed.

The value of data is not a new thing, whether in business or in warfare.

Either the goal of precision marketing or the material collection for machine learning,
their intentions can be shorten into one word: data, the oil in the digital era.

Not surprisingly, data storage and marketplace turn into new challenges.In this session, we'll introduce an innovative type of data marketplace platform with distributed legder technology (DLT) to transform data into profits with better trust basic.

Let's explore the Bitcoin protocol by building a Bitcoin client from scratch, one that connects with other Bitcoin nodes and accesses data stored on the chain of blocks. I will introduce relevant concepts (such as tx, utxo, block, address, op-code) as we implement the components. To add to the fun, we'll trying doing this in a safe systems language, Rust.

The Internet today is plagued by many problems. From viruses and spam, to identity theft and piracy.

We can solve those problems.

With a virtual operating system that runs the cloud, using blockchains to secure identities and data, a virtual network layer to protect agains unauthorized network access, and a virtual machine to sandbox untrusted code.

This talk will describe Elastos, an Operating System for the smart web.

It will explore the approach that Elastos takes to achieve these goals, and gives a vision of a possible future internet.
