NChain, whose chief researcher Craig Wright had previously stated that he was the creator of Bitcoin Satoshi Nakamoto, while actively promoting Bitcoin Cash, received the latest patent in Europe for "invention in the field of digital security". This is reported by Bitcoinist.

This Deterministic Key Generation technique provides for improved secure communication between a pair of nodes or parties on a network, while being able to keep their private keys secret.

nChain is trying to create a set of tools on the blockchain to carry out cross-border transfers through the so-called "Internet transactions".

Wright's company continues to attract attention due to ambiguous marketing decisions. Last month, at a conference in Rwanda, Wright told the audience that "he has more money than the whole of their country."

This looks like they're trying to patent plain old public master key-based deterministic wallets, like what we had in 2013. Can't someone attack it in court with the obvious mountains of prior art?

In the past, Buterin repeatedly accused Wright of fraud.

Describing the possibilities for applying the present invention, nChain CEO Jimmy Nguyen said that their technology has been recognized by the Japanese technology conglomerate SBI.

The developers of the MetaMask Ethereum wallet wallet have opened the way for everyone to test the beta version of a mobile application available for Android and iOS.

According to the developers, the application is synchronized with the cryptowallet in the initial browser extension. It also allows you to manage crypto-assets, send ETH users and ERC-20 and ERC-721 standard tokens using ENS names (Ethereum Name Service), and interact with decentralized applications (dApps).

In addition, the application supports InstaPay payment channels for instant and free transactions. It also implements Web3 functionality, support for IPFS and various solutions to ensure a high level of security.

The launch of the mobile application MetaMask was announced 9 months ago during the Devcon4 conference in Prague.
