A few hours before the The Year in Ethereum 2019 report release, Diederik Loerakker, who is working on ETH2 specifications and implementations, published a quick development update on the progress towards Ethereum's most exciting milestone of 2020.
What do they have so far?
Mr. Loerakker has given a sneak peek of the ETH2 up-to-date progress. According to him, Ethereum (ETH) 2.0 Phase 0 (also dubbed 'Beacon Chain') is now stabilized. Moreover, even the Phase 1 draft is completed. It shows how the interaction between shards will be organized in the new Ethereum.
The researcher leaked that it is 'based on the DevCon cross-shard UX' and is subject to various testings. E.g. it can be investigated through the 'custody game' sandbox that emulates the ETH2 cryptoeconomics.
Finally, the network tools have been moved to a new Simple Serialize (SSZ) serialization algorithm standard for all data structures. This upgrade has already resulted in high-end client performance.
Moreover, Mr. Loerraker has written that the next stage of development will start from the merging of three top pull-requests in Ethereum 2.0 GitHub. Thus, the researcher can switch his efforts towards building new monitoring tooling for the testnets.
Ethereum (ETH) 2.0 is the next stage of Ethereum network development that will replace the Proof-of-Work consensus with a Proof-of-Stake concensus. Also, the whole Ethereum (ETH) blockchain will be divided into shards - interconnected blockchain items.
