Ethereum testnet attacked

Ethereum testnet is reported to be under spam attack

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. 

Monoplasma Ethereum Scaling Technology Unveiled

The developers of the blockchain platform Streamr presented a solution for scaling the Ethereum network called Monoplasma. It is reported by CoinDesk.

The creators of the project claim that the technology will help solve the problem of repeat payments from one address to many others. Monoplasma, in their opinion, will be useful to developers of decentralized applications focused on the distribution of dividends, staking and repeated airdrops.

The head of Streamr, Henry Pinkala, also demonstrated fake token airdrop for 200 thousand Ethereum addresses in a test network using Monoplasma.

You can receive money, but you can’t send back the other way. That would be like trying to send a message to your TV.

Thus, Monoplasma payment channels are reliably protected from the attack of double waste.

Streamr intends to use a new solution for the mass sale of user data on the blockchain, allowing the buying company to settle accounts with many users at once.
