Ethereum can launch Casper testnet soon

Ethereum developers are looking to use code for their experimental Casper proof-of-stake protocol as the basis for a new test network

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.

Constantinople Hardfork Code to be Included in Geth

Go-ethereum (Geth) v1.8.20 assumes that hardfork in the main Ethereum network will take place at block 7,080,000 (approx. between 14th - 19th Jan 2019)

Developers of Geth, one of the most popular clients of Ethereum, presented a new version of the software with the included code of the upcoming hard fork Constantinople.

Go-ethereum (Geth) v1.8.20 assumes that hardfork in the main Ethereum network will take place at block 7,080,000.

Consensus regarding the block number for activating hard forks was reached last week during a regular video conference of leading Ethereum developers. According to Afri Shedona, release manager of another popular client of the network Parity, a block of 7,080,000 will be mined between January 14 and 18, 2019.

At the same time, Ethereum Foundation’s head of security noted that the new version of the go-ethereum client would contain a kind of “emergency switch” that would postpone the upgrade if something went wrong.

Originally scheduled for November, the Constantinople contains a number of changes and code optimizations designed to ease the transition to the Proof-of-Stake algorithm. In particular, they include the transfer by 18 months of the so-called “bomb of complexity”, which contributes to timely upgrades, and also suggests a decrease in the reward to miners from 3 to 2 ETH for the mined block.
