PublicAI

Converts natural language questions into executable smart contract queries using LLM-based semantic parsing and contract ABI schema mapping. The system analyzes user intent, maps it to contract function signatures, and generates optimized query parameters without requiring developers to write low-level blockchain code. This reduces friction for Web3 developers unfamiliar with contract ABIs and RPC call semantics.

Maintains a distributed cache of frequently-accessed blockchain state (balances, allowances, contract storage) with automatic invalidation on new block finality. Uses event-driven architecture to subscribe to contract logs and update cached state incrementally rather than re-scanning the entire chain. Implements multi-level caching (in-memory, Redis, persistent) with configurable TTLs to balance freshness vs query latency.

Maintains immutable audit logs of all blockchain data queries and modifications, tracking who accessed what data, when, and for what purpose. Links query results back to source transactions and blocks, enabling data lineage tracing. Integrates with compliance frameworks (SOX, HIPAA) to generate audit reports for regulatory purposes.

Validates zero-knowledge proofs embedded in blockchain transactions to verify sensitive data (private balances, confidential transactions) without exposing the underlying plaintext. Implements proof verification circuits compatible with major ZK frameworks (Circom, Cairo, Noir) and validates proofs against on-chain commitment roots. Enables querying encrypted blockchain state while maintaining cryptographic privacy guarantees.

Applies declarative validation rules to blockchain data before returning query results, ensuring type correctness, value bounds, and business logic invariants. Uses a schema definition language to specify expected data types, ranges, and relationships across contract state. Validates decoded contract storage and function outputs against these schemas, catching data corruption or contract bugs before they propagate to applications.

Abstracts away chain-specific differences (RPC endpoints, block times, finality rules) and provides a unified query interface across Ethereum, Polygon, Arbitrum, Optimism, and other EVM chains. Handles chain-specific quirks (different block confirmation times, reorg depths) transparently and returns results with consistent schemas. Supports cross-chain state queries by coordinating requests across multiple chains and merging results.

Analyzes incoming queries and recommends optimizations (batching, caching, index selection) to minimize RPC calls and associated costs. Estimates gas costs and RPC provider fees before query execution and suggests alternative query patterns with lower costs. Uses historical query patterns and chain state analysis to predict optimal execution strategies.

Stores sensitive blockchain metadata (private keys, transaction signing data, user identifiers) in encrypted vaults with encryption-at-rest and encryption-in-transit. Uses envelope encryption with key derivation from user credentials, ensuring PublicAI cannot access plaintext data. Integrates with hardware security modules (HSMs) for key management in enterprise deployments.

Streams blockchain events (contract state changes, transaction confirmations, reorgs) to applications via webhooks or message queues with guaranteed delivery semantics. Filters events based on user-defined predicates (e.g., only notify on transfers >1000 tokens) and deduplicates events across reorgs. Supports multiple delivery backends (HTTP webhooks, Kafka, AWS SQS, Google Pub/Sub).

Verifies the authenticity of blockchain transactions and smart contract interactions using cryptographic signatures and on-chain identity registries. Validates that transaction signers match expected identities (EOAs, multisigs, contract accounts) and checks against revocation lists or reputation systems. Supports multiple identity verification standards (EIP-191, EIP-712, SIWE).

Groups multiple blockchain queries into optimized batches and executes them in a single RPC call or transaction bundle, reducing overhead and improving throughput. Automatically detects independent queries that can be parallelized and dependent queries that must be sequential. Supports transaction bundling for MEV-resistant execution via Flashbots or similar services.
