1. Crypto-Powered Brave Browser Surpasses 10 Million Downloads on Google Play

The Brave browser, an open-source internet browser created by Brave Software Inc., has now been downloaded over 10 million times from Google’s Play Store. Notably, this could mean there has been a significant increase in the number of people using the privacy-oriented web browser, as it reportedly only had 3.1 million active users in July.
In April, there were about 2.2 million users who had installed the Brave browser, while its Android version was ranked among the top 10 “Free Communication Apps” on Google’s Play Store in more than 20 different countries, including the US and Canada.

블록체인 웹 브라우저인 Brave browser 가 구글 플레이 스토어 1,000만 다운로드를 돌파하였습니다. 7월 310만에 비하면 빠른 성장세를 보이고 있는데 Basic Attention Tokens’ (BAT) payment system 지원하는 것도 긍정적 요인이겠지만 Brave browser를 이용하는 사용자에게 BAT를 지급하는 것이 큰 원인인 것으로 보입니다.

AD블록을 지원하면서 광고를 보는 사용자에게는 BAT를 지급하는 방안도 계획 중이라고 합니다.

2. How Blockchain Can Help Fight Child Labor Abuses in Congo’s Cobalt Supply Chain

A relatively rare metal, cobalt is a crucial component of the rechargeable lithium-ion batteries used in smartphones, electric vehicles, and a whole host of electronics. Most of the world’s cobalt supply comes from the Democratic Republic of the Congo (DRC) where the practice of using child labor to mine the metal runs rampant. With the continued push toward responsible and ethical sourcing, companies are looking at ways to ensure that the cobalt they purchase is not the product of child labor. Blockchain technology may provide the answer.

How Blockchain Can Help Fight Child Labor Abuses in Congo’s Cobalt Supply Chain

A relatively rare metal, cobalt is a crucial component of the rechargeable lithium-ion batteries used in smartphones, electric vehicles, and a whole host of electronics. Most of the world’s cobalt supply comes from the Democratic Republic of the Congo (DRC) where the practice of using child labor to mine the metal runs rampant. With the continued push toward responsible and ethical sourcing, companies are looking at ways to ensure that the cobalt they purchase is not the product of child labor. Blockchain technology may provide the answer.

The Democratic Republic of the Congo (DRC) is a hotbed of corruption, political unrest, and violence. As a result, despite the country’s abundant natural resources, extreme poverty is the norm for much of the country’s 84 million people. It is perhaps ironic, then, that an estimated 65% of the world’s cobalt supply comes from the world’s poorest country.
Out of all of the cobalt mined in the DRC, roughly 20% of it is “artisinally mined” – a more palatable way of saying that it is mined by hand – and much of that mining is done by children. In fact, the latest research by UNICEF estimates that there are as many as 40,000 children – some as young as 7 years old – mining cobalt in the country.
Companies like Apple, Tesla, Volkswagen, and others are looking for ways to ensure that the cobalt they purchase is ethically sourced and not produced using child labor. One of the avenues being explored to help ensure the integrity of the cobalt supply chain, according to Fortune magazine, is blockchain technology.
Using Blockchain to Keep Child Labor Out of the Cobalt Supply Chain
London-based human rights NGO Amnesty International has been looking at blockchain as a way to make sure that mined cobalt in the region remains “clean” – that it hasn’t been the product of child labor.
A pilot program, proposed in February of this year, would involve vetting miners and providing them with a digital tag. Each bag of cobalt produced by the miner would then be sealed, tagged, and entered on the blockchain via a mobile device along with details such as weight, date, time, the miner’s name, and even photos.
From there, each step in the supply chain would involve each person taking custody of the bag recording additional information on the blockchain. The end result is an immutable record of every step that bag of cobalt took, from mine to smelter, that buyers or any other third party can view.

코발트가 리튬-이온 배터리에 쓰이면서 코발트 생산량의 많은 부분을 차지하는 콩고지역에서 아동 노동 착취가 문제가 되고 있는데, 이 문제를 블록체인을 통해 해결하고자 하는 연구가 진행되고 있다고 합니다.

즐거운 하루 보내세요 ^^
