Ethereum 2.0’s latest development is typically split into phases. Phase 0 is the Beacon Chain of barebones that makes staking, but has no impact on the application layer. Phase 1 introduces data sharding, increasing storage capacities without directly impacting the performance of the application. Finally, Stage two fully introduces transaction sharding and allows thousands of transactions per second of throughput to be promised.
Buterin said this blueprint for the road map is a vision for the next five to ten years in March. The latest version is fluid and fully excludes terms such as “Phase 1” and “Phase 2.” Each phase’s defining features are now more exclusive and include work done on Ethereum 1.x. Buterin’s roadmap covers all Ethereum developments to include a comprehensive description, including approximate completion bars of the network.
“The roadmap I made back in March updated with (very rough and approximate!) progress bars showing what has been done and some of the recent tweaks to the roadmap itself. A lot has been accomplished, but still a lot remains to be done!” Vitalik tweeted on December 1, 2020.
The main aspects of the next big milestone include the transition from Ethereum 1.0 to proof-of-stake, the implementation of Eth2 light clients on Eth1, and data sharding, all of which were previously grouped under Phases 1 and 1.5. An significant improvement to the new Roadmap is the recognition that the three phases are completely separate and can be worked on in parallel. progress on data sharding and light clients is still at or below 50%, according to Buterin, consistent with estimates that Phase 1 will take at least one year to build.Development on stateless clients and the Ethereum 1.x project is still below 50 percent, according to the chart. The cryptographic technology of polynomial commitments is still far from complete. Likewise, work on several other complex types of cryptographic technology and an enhanced virtual machine is still in its early stages.
