The developers of Ethereum intend to use the experimental code Proof-Of-Stake protocol Casper as the basis for a new test network. This is reported by CoinDesk.
The founder of Ethereum Vitalik Buterin at the kernel developers' meeting suggested not only to test the protocol code written in Python, but also expressed confidence that Casper could improve the security settings during Ethereum-client testing.
Ropsten is the only test network supporting the participation of all Ethereum clients, but it works on the basis of the Proof-Of-Work algorithm. Due to the weak support of the miners, the network often becomes the target of DDoS attacks. The remaining test sites - Rinkeby and Kovan - use the Proof-Of-Authority protocol to eliminate such threats, but the lack of interoperability is not suitable for many developers.
If we realistically want to roll out Casper in whatever hard fork, then eventually people need to start implementing it.
Buterin acknowledged that there were some security gaps with regard to the new protocol, and he suggested that the Ether development be delegated to several developers in the test network, which partially duplicates the consensus of the Proof-Of-Authority.
The participants agreed to conduct a series of studies to assess the potential of the test network. The mission was assigned to the developer Piper Meriam, who will work with the teams of clients Parity, Geth and actually Casper.
Earlier, the test site Ropsten was target of DDoS-attacks on the eve of Byzantium's hardfork, which was successfully held on October 16. The network update was the first step of the Ethereum developers on the way to implementing the Proof-Of-Stake consensus algorithm within the framework of the large-scale Metropolis hardfork.
