v1.1.0-alpha — Trustless Transaction History

[AugustoL]

OpenScan v1.1.0-alpha Release Notes

Trustless Transaction History is Here

We're excited to announce OpenScan v1.1.0-alpha — featuring a groundbreaking approach to fetching transaction history without relying on centralized indexers.

Direct from the blockchain. No intermediaries.

Highlight: Binary Search Transaction Discovery

Traditional block explorers rely on centralized indexers to show your transaction history. OpenScan takes a different approach.

How It Works

Our new binary search algorithm finds your transactions by analyzing on-chain state changes:

1. Outgoing transactions — Detected by tracking nonce changes across blocks
2. Incoming ETH — Detected by tracking balance changes across blocks

The algorithm efficiently narrows down which blocks contain your transactions, then fetches the actual transaction data directly from your configured RPC.

Features

• Streaming results — Transactions appear as they're found, no waiting for full scan
• Configurable limits — Search for 5, 10, 50, or all transactions
• Local caching — Results cached for 1 week to avoid re-scanning
• Search recent — Find new transactions since your last search
• Progress indicator — Visual progress bar with cancel button
• No indexer required — Works with any standard Ethereum RPC

Trade-offs

This approach is not as fast as centralized indexers, but it's the most trustless way to fetch account transactions. You're querying the blockchain directly through your own RPC — no third-party APIs, no data collection, no trust assumptions.

For accounts with many transactions, the initial search may take some time. But once cached, subsequent visits are instant.
