Releases Experimental Authenticators for Google Chrome, Safari

The developers at, a Cayman Islands-registered open-source software publisher focused on the ongoing development of EOS, one of the largest platforms for building and deploying decentralized applications (dApps), have released a set of Reference Authenticator apps.

The apps have been launched as “experimental reference Open Source Software”,’s development team clarified. As noted in a blog post published on May 29, 2019, by the leading blockchain-powered software developer, the Reference Authenticator apps are available for iOS users.

Key Management and Signing Protected by Biometric Authentication

The distributed ledger technology (DLT)-based software allows users to log in and approve transactions from web-based applications running on the mobile Safari browser,’s blog mentioned. Additionally, it stated users may access the Reference Authenticator from “other native iOS apps on the same device."

As explained in the software publisher’s blog, key management and signing are performed in Apple’s Secure Enclave and/or Keychain and are “protected with the device’s biometric authentication.”

Signing in and Approving Transactions via Google Chrome, Safari

In order to provide this type of security, the apps “leverage” the recently-introduced EOSIO software development kit (SDK) for Swift library and its “Vault Signature Provider.” This type of functionality allows users to authenticate and sign transactions from third-party mobile apps,’s blog explained.

The software development firm’s blog further noted that the Reference Authenticator apps are now also available as a Google Chrome Extension. This will allow users to sign in and approve their transactions directly from web-based apps that are opened using the Google Chrome browser (from both mobile and desktop computers). A secret passphrase, managed by the user, is used to secure the key management and signing process.

Tropical Stay App Demonstrates How Login and Transaction Verification Process Works

Web-based apps are also able to integrate (or are compatible) with the EOSIO Reference Authenticator apps, by using the Universal Authenticator Library and “the EOSIO Reference Authenticator plugin for UAL.”’s latest Reference Authenticator release package also includes a newly developed Tropical Stay app, which shows how the sign in and transaction verification process works. Moreover, developers may directly use EOS Javascript (EOSJS) and an appropriate signature provider to accomplish the same tasks.

Notably, the EOSIO Reference Authenticator apps are “entirely chain agnostic” and they have been implemented in a manner that does not require communication with EOSIO nodes directly.

Ousted Bitmain Co-Founder Storms Company Offices With Private Security Guards

Micree Zhan, co-founder of cryptocurrency mining hardware manufacturer Bitmain, has reportedly stormed the company’s offices in Beijing with private security guards in a bid to take back control.

According to local news outlet Blockbeats, the moves comes amid a battle for control over Bitmain between its two co-founders, Micree Zhan and Jihan Wu. Zhan reportedly took over the Beijing offices with private security guards and then sent a letter to shareholders and employees, stating he was in control of the office and encouraging employees to return to work.

On social media an edited version of the video of Zhan storming the offices is circulating.

In the letter, Zhan apologized for the recent turmoil at the company and said he would take it public in hopes of raising funds through an initial public offering and getting its value up to $50 billion within five years.

On its Weibo account, Bitmain claimed Zhan has been removed from his position as a legal representative for the Beijing subsidiary of Bitmain, and that a team of lawyers will be pursuing litigation. Under Chinese law, it’s worth noting, a legal representative has powers over the company’s capital and assets, and as such the title is usually held by the CEO.

Battling for Bitmain

Bitmain’s co-founder, it’s worth noting, have been battling each other since October 2019, when CEO Jihan Wu ousted Zhan from the firm, sending staff an email informing them they were to “no longer take any direction from Zhan, or participate in any meeting organized by Zhan.” Bitmain could, per the email, “consider terminating employment contracts” for those who went against the email.

The internal dispute between Zhan and Wu started over different opinions on Bitmain’s future. While Zhan believes the firm should diversify and start offering silicon specialized towards artificial Intelligence, Wu has fought for it to pursue cryptocurrency mining-related operations.

After Bitmain failed to go public on the Stock Exchange of Hong Kong, Wu left the company but later on return with shareholder support, saying he would take legal action to regain control over it. At the time, Wu said:

Bitmain is our child. I will fight for her till the end with legal weapons. I won’t allow those who want to plot against Bitmain to succeed. If someone wants a war, we will give them one.

At the time control of the company was given to Zhan, but the conflict escalated on May 8 at the Haidian District Administrative Service Center, as when the co-founder was there to collect documents, dozens of others showed up, including Bitmain’s current CEO Liu Luvao. According to Caixin, a physical fight ensued and police had to be called.
