The post additionally added that “this marks the primary release within the series of weekly releases through Feb. 2019. Phase zero in v0.1 comparatively features complete and approaching stable.”
Ethereum 2.0, also called Serenity, is planned to be the system’s final upgrade, as the entire network transitions from a PoW [proof-of-work] to PoS p[roof-of-stake] operational algorithm, and tackles elementary queries like measurability, economic finality along with security.
Serenity therefore represents the last in a series of 4 stages embarked on within the platform’s roadmap; at present, the network is in its third stage named Metropolis which consists of 2 system-wide hard forks dubbed Byzantium and Constantinople — both designed to pave the way to Ethereum 2.0. The latter was notably recently delayed because of a vulnerability issue detected while its prior launching date in mid-Jan.
Commenting on today’s initial pre-release for Serenity, Ethereum co-founder Vitalik outlined it absolutely was “basically feature complete for Casper.” As according, Casper FFG — that stands for Casper the Friendly finality gadget — was initially ‘revealed‘ in Oct. 2017, as a PoS-PoW hybrid agreement model designed to offer stronger economic finality and security.
Other PoS solutions planned for Ethereum 2.0 notably embrace the sharding scalability feature — that split ups transactional processing between smaller teams of nodes to hike the blockchain’s total output.
For developers, a testnet provides a simulated version of the first network that enables them to try out smart contracts or upgrades while not having to pay “gas” [transaction fees) for their execution.
Gorli which is an open source community-built initiative — can reportedly be instrumental in synching several other major Ethereum shoppers like Parity, Geth, Nethermind, Pantheon and EthereumJS.
As ‘reported‘ earlier, the vulnerability that was found within the Constantinople hard fork last month was one that would have allowed for reentrancy attacks via the utilization of certain commands in ETH smart contracts. This vital issue was initially detected by smart contract audit firm named ‘ChainSecurity’.
