Configurable finality describes a blockchain property allowing users or protocols to set conditions for transaction irreversibility. It provides flexibility in confirming transaction permanence based on varying security needs or latency requirements. This feature can allow for faster, less secure confirmations for small transactions. It also enables stronger, slower confirmations for high-value transfers. This represents an adjustment to the trade-off between transaction speed and security guarantees.
Context
Configurable finality is a significant topic in scaling solutions and enterprise blockchain adoption, addressing diverse operational needs. Discussions consider its utility in different application scenarios, from high-frequency trading to secure settlement systems. The primary focus is on how this flexibility can enhance the practical utility and performance of various blockchain networks.
This research pioneers a dual-proof rollup system, integrating ZK-STARKs and TEEs to deliver configurable finality and flexible security-cost trade-offs for Layer 2 solutions.
