ConsenSys, founded by Ethereum co-creator Joseph Lubin, provides a comprehensive introduction to Ethereum 2.0's most common questions, along with an exhaustive list of learning resources.
What is Ethereum 2.0?
Ethereum 2.0, also known as Eth2 or "Serenity," is the next major upgrade to the Ethereum blockchain. It will be rolled out in multiple "phases," starting with Phase 0 in 2020. Each phase introduces improvements to Ethereum’s functionality and performance.
Key Differences Between Ethereum 1.0 and Ethereum 2.0
Ethereum 2.0 introduces two major enhancements: Proof of Stake (PoS) and Shard Chains.
Proof of Stake: Currently, Ethereum 1.0 operates on a Proof of Work (PoW) consensus mechanism, relying on physical computing power (miners) and electricity. PoS replaces this with a virtual mining system where validators stake ETH to secure the network. This upgrade improves security, scalability, and energy efficiency.
Shard Chains: These are scalability mechanisms that split Ethereum’s blockchain into 64 parallel chains, enabling concurrent transaction processing. This design aims to increase throughput by 64x or more compared to Ethereum 1.0. Shard Chains are expected in Phase 1.
Ethereum 2.0 Roadmap: Phases and Timelines
Ethereum 2.0 will launch in three phases:
- Phase 0 (2020): Introduces the Beacon Chain, which manages validators and implements PoS. The original PoW chain continues running alongside.
- Phase 1 (2021): Integrates Shard Chains for parallel processing.
- Phase 2 (2021–2022): Adds cross-shard transactions, account functionality, and merges Ethereum 1.0 into Ethereum 2.0.

How Will Ethereum 2.0 Improve the Network?
Key upgrades include:
- Scalability: Shard Chains increase transaction capacity.
- Security: PoS reduces attack risks.
- Sustainability: Lower energy consumption than PoW.
What Happens to Ethereum 1.0?
The Ethereum 1.0 chain will eventually become the first shard in Ethereum 2.0, ensuring continuity of data and assets.
FAQs
1. Can I buy Ethereum 2.0 tokens?
No new ETH tokens will be issued. Existing ETH can be staked in Ethereum 2.0’s deposit contract.
2. How do I become a validator?
Stake 32 ETH and run a validator node or use a staking service.
3. What are the risks of staking?
Validators may lose staked ETH if they act maliciously or go offline frequently.
4. When will Ethereum 2.0 launch fully?
Phase 0 launched in 2020; Phases 1 and 2 are expected by 2021–2022.
