The post Ethereum applications at the On-chain Summit appeared on BitcoinEthereumNews.com.

Ethereum applications dominated discussion today at the Global On-chain Asset Summit in Singapore, hosted by HashKey Group, where Vitalik Buterin and Dr. Xiao Feng outlined practical paths for scaling, identity and risk control on-chain. What was the main message from the summit about l1 l2 application differences? Speakers drew a clear line between Layer 1 and Layer 2 use cases. L1 remains the canonical base for settlement and shared security. L2s are framed as the layer for high throughput and lower fees. In this context, developers should design with cross-layer interoperability in mind. Applications that need finality and censorship resistance will favor L1. By contrast, high-frequency use cases — such as prediction markets and micropayments — gain from L2 throughput and reduced costs. How does this affect developers choosing where to deploy? Teams must weigh latency, fees and trust assumptions. Many prototype on L2, then shift critical settlement logic to L1 when guarantees matter. Tooling for bridging and observability is improving, which reduces migration friction. How did the speakers address ethereum prediction markets and their scaling? Panelists discussed the promise of ethereum prediction markets for price discovery and hedging. They underlined that such markets need fast finality and low fees to operate efficiently. As a result, builders plan to run market engines on L2 or rollups while anchoring outcomes on L1. This hybrid model preserves security and delivers the speed traders require. However, throughput targets and oracle designs remain under debate. Are there regulatory or market risks traders should watch? Yes. Speakers flagged regulatory scrutiny and liquidity fragmentation as material risks. Choosing venues with transparent on-chain settlement and reputable layers reduces counterparty exposure. What role will zk identity proofs play in on-chain user models? Experts positioned zk identity proofs as a core tool for privacy-preserving KYC, Sybil resistance and reputation…
