Ethereum Testnet Has Suffered A Spam-Attack


Ethereum network has suffered a spam attack. As noted, the failures in the Ropsten network began when testing new software. The Ethereum developers plan to activate it during the upcoming hardfork called Byzantium. At the same time, they argue that attackers are unlikely to be able to influence the timing of the activation of hardfork and there are no serious reasons for concern.

The spam-attack has pushed developers to move into a more secure network Rinkeby. But according to the developer of Raiden, Lefteris Karapetsas, network Ropsten is the closest analogue of the original Ethereum blockchain.

Spam-attack the Ropsten

The attackers have filled the Ropsten network with thousands of automatically generated spam transactions. The last such attack happened in March, and then the Ethereum team has forced to re-write a test version of the blockchain.

The team countered the attacks due to the increase in the cost of transactions, but this step adversely affected the possibilities of further testing the software. Subsequently, the developers stopped for a time to operate testnet Ropsten.

“This brought us a lot of inconvenience and distracted from the work,” commented Ethereum developer,  Casey Detrio, expressing confidence that the date of the hardfork will not be postponed.

In general, developers do not quite understand the reasons for the attacks on the test network.

“It seems to me that they just enjoy it,” Detrio concluded.

Ropsten is one of three test versions of the Ethereum network using for testing updates. One of its features is that Ropsten supports two main Ethereum clients: Geth and Parity. In addition, it is unique in that it can fully emulate the consensus algorithm Proof-of-Work.
