Use-Cases

Category	Use Cases	Description	Validator Set Importance
DeFi	Oracles, Cross-Chain Bridges, Advanced Financial Protocols.	Utilize validator security to provide reliable pricing, liquidity transfers, and novel financial mechanisms.	Requires strong decentralization and reliability to prevent fraud, ensure data accuracy, and maintain trust.
Data	Data Availability, storage, Rollups.	Provide guaranteed data availability for Layer 2 rollups and other off-chain data solutions.	A strong validator set ensures reliable data publication, mitigating risks related to data withholding or loss.
Off-Chain Computation	Co-processors, Ad-hoc execution, Verifiers.	Offload computation and storage to a decentralized network while maintaining verifiability.	Requires trusted validator nodes to ensure computation results and data are correct and verifiable.
Security as a Service	Fraud Proofs, Slashing Mechanisms, Firewalls, Attack Detection.	Offer additional security services to other blockchain protocols like slashing and fraud detection.	Needs an equally robust validator set to that of Ethereum to uphold network integrity, enforce accountability, and provide effective deterrence against attacks.
Middleware Extensions	Relayers, Indexers, Event Streaming.	Middleware infrastructure to bridge different blockchain layers or to provide specialized services.	The validator set must be trustworthy to maintain secure cross-layer communication and accurate data indexing.
Governance & Coordination	DAOs, Collective Voting Systems, Community Funds.	Facilitate decentralized governance and coordination processes in a transparent and trustless manner.	A decentralized validator set is essential to ensure decisions are executed without manipulation or central authority.
Cross-Chain Communication	Interoperability Layers, Message Passing Protocols.	Enable communication and asset transfer across multiple blockchains	A secure validator set ensures the reliability and trust in communication between distinct blockchain ecosystems.
Economic Security Extensions	Bonded Validators for Collateralized Systems.	Provide collateral and bonded services for systems requiring economic guarantees.	A validator set as strong as Ethereum ensures economic guarantees, minimizing risk of financial loss due to validator failures.
Validator Commitments	Pre-Confirmations, Based Sequencers, Transaction Ordering.	Validators provide additional services like pre-confirmation of transactions, sequencing, and ordering to reduce latency and optimize blockchain efficiency.	A robust validator set is essential for pre-confirmations to provide guarantees on finality, while based sequencers ensure fair and predictable transaction ordering to enhance network performance and mitigate risks associated with transaction manipulation.
