Following the successful launch of Ethereum 2.0 Phase 0 — the first concrete step in building the next iteration of the protocol — Ethereum co-founder Vitalik Buterin published an updated roadmap of what comes next for the project.
The current development of Ethereum 2.0 is generally divided into phases. Phase 0 is the barebones Beacon Chain that enables staking but has no effect on the application layer. Phase 1 introduces sharding of data, increasing storage capabilities without directly influencing application performance. Finally, Phase 2 fully introduces transaction sharding and enables the promised thousands of transactions per second of throughput.
