Another busy week for the Qtum team, along with the Decentralized Applications that are building on our platform. Patrick spoke at Cointelegraph’s Blockshow Asia conference, and Miguel is due to speak at the Labit Conference in Colombia today. There was on online event with Patrick Dai and OKEX.com, as well as an AMA on our subreddit with CFun.

Qtum was listed as one of the Blockchains available on the Ledger Nano and Blue devices. We were also one of the 100+ projects listed on Yahoo! Finance earlier this week.

On the development front, our Lead Developer, Jordan Earls has provided some updates, which will be listed near the bottom of this article. We are moving away from the weekly list of development updates, but our progress can be tracked at the Qtum official Github repository.

Qtum DAPP Updates

StormX

While this is not a project building on Qtum, their crowdsale is almost finished. Please remember you can receive a 30% discount when you purchase StormX with Qtum tokens. Please see their website, and the article we wrote about them here:

Robin8

This Qtum Decentralized Application has a working product and customers, they will be tokenizing their business model on our platform. They have an artificial intelligence engine, which profiles and ranks people based on their social media reach, and allows them to monetize their own profiles to advertisers. This completely disrupts the traditional ‘placement advertising’ models that Google and Facebook use, which basically turns their userbase into products, and does not compensate them for their content.

Energo

December 5,2017: Energo Labs has officially become a member of the Philippines Energy Efficiency Alliance (PE2), which consists of other internationally renowed companies including Philips, Engie, Meralco Energy Inc (MServ) among others. As a non-profit, self-governing body, PE2 is dedicated to accelerating the deploayment of energy efficiency (EE), energy saving (EC) and renewable energy (RE) technologies to accelerate the transformation of the energy sector in the Philippines. PE2 is also involved in pushing for policy reform in the Filipino energy sector, has established the Philippine Council for an Energy-Efficient Economy (PCE3), and is involved in the enforcement of a policy by the Department of Energy (DOE) on a Substitute EE bill.



By becoming a member of PE2, Energo Labs will get involved in promoting distributed and decentralized energy in the Philippines, reaching a step towards building more Decentralized Autonomous Energy (DAE) communities on a larger scale.

CFun

On Friday, December 1st, CFun held an AMA in two locations; the Qtum subreddit, and on Kakaotalk. Some of the questions from the Korean community were translated and posted on the subreddit. There were a few dozen questions about the project as they head into their crowdsale phase. For more information, please see the thread on the Qtum subreddit, or visit CFun’s website:

Qtum Now Available on Ledger Devices

Qtum, along with Digibyte and Hcash, are now supported by Ledger hardware wallets. This is likely the safest way to store your tokens, so we recommend that you use either the Qtum QT wallet, or a ledger nano. Never leave your tokens on an exchange.

Please see Ledger’s website for more information:

Qtum Listed on Yahoo! Finance

Qtum, along with 100+ Blockchain projects was listed on Yahoo! Finance. This application has 5 million+ downloads on the Google Play store alone. Here is the download link:

JB395’s “Qtum Mainnet Results: Nov 7th — Dec 3rd

Jackson Belove goes into depth about Orphan blocks this week. As always, he goes above and beyond when explaining how and why this happens. A quick excerpt from his article:

“ Let’s start by considering the nature of distributed peer-to-peer mining by full nodes (wallets) for a generic cryptocurrency. All these wallets are working hard (for Qtum, not so hard) to solve the SHA-256 hash algorithm and win the next block reward. It is inevitable that occasionally two wallets will simultaneously solve for the next block, and both think they will get the block reward.”
