A version of the Ethereum blockchain used to test a forthcoming network upgrade is reported being under spam attack.

The attack consists of a Ropsten address swarming the blockchain with thousands of auto-generated, faulty transactions. Since its start, the attacks have continued in waves, "leading the spammer and the developers into a game of cat-and-mouse to keep the fake transactions from interrupting the network". 

At the time of writing, it seems that the developers have successfully staved off the attacker by raising the cost of transactions. Ethereum developer Casey Detrio believes the attacker will not delay the Byzantium test period. The man told to on coindesk.com:

It's only a distraction and inconvenience.

Still, it's not exactly clear to the developers why someone would attack a test blockchain.  The disruptions occurred when the developers were testing Byzantium, an upcoming hard fork of the platform. As reported, the spam attack resulted in turning of some developers into a more secure test environment, Rinkeby.

The developers assure there's no reason to believe the attacker will delay the hardfork, which is planned for October 17th.

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.
