- Deposit funds into a smart contract on Ethereum 1.0
- Await activation and participate in consensus via proof-of-stake
The Beacon Chain introduces slashing conditions to penalize malicious behavior and supports validator exit mechanisms for secure unstaking.
Wang also outlined upcoming milestones:
- Stable testnet deployment
- Interoperability between client implementations
- Standardization of new signature schemes
Vitalik Buterin on Cross-Shard Transactions
In a highly anticipated talk, Vitalik Buterin addressed one of Ethereum 2.0’s most complex challenges: cross-shard transactions.
With 1,024 planned shards, ensuring atomicity across shards is critical. Buterin proposed a solution called the "Yank" mechanism—an asynchronous coordination method inspired by database locking—to prevent race conditions (e.g., double booking a hotel and train ticket on different shards).
He also discussed:
- The role of Optimistic Virtual Machine (OVM) concepts in simplifying cross-shard logic
- Challenges in wallet design due to increased computational load
- The need for global consensus on data storage and balance tracking
Buterin stressed that ETH 2.0 aims to scale throughput from ~10 TPS to over 10,000 TPS, unlocking mass adoption for DApps.

Phases of secure data flow:
- Enterprise internal data sharing (3–5 years)
- Inter-enterprise secure collaboration (5–10 years)
- Personal data monetization (10–20 years)
MPC eliminates the need for trusted third parties and integrates naturally with blockchain’s decentralized architecture.
ECT: Confidential Transactions with Accountability
Tang Cong, founder of Ethereum Confidential Transaction (ECT), introduced PGC (Pretty Good Confidential)—a privacy layer for Ethereum that hides account balances and transaction amounts while maintaining auditability.
Key innovations:
- Homomorphic encryption + zero-knowledge proofs
