FlashStat: Unichain Soft-Finality Infrastructure 🏮

One Block: The Transparency Layer for Ethereum

FlashStat is the first dedicated infrastructure suite for monitoring Soft Finality on the Unichain network. By tracking 200ms Flashblocks in real-time, we provide the "Confidence Layer" necessary for wallets and DApps to safely adopt Unichain's extreme performance.

📍 Part 1: Technical Proof-of-Concept (POC)

This repository contains a high-performance Rust skeleton that proves the feasibility of real-time soft-reorg detection.

🏮 High-Frequency Monitoring

Unichain produces blocks every 200ms. This POC demonstrates:

  1. Chain Integrity: Verifies the parent_hash chain at a 200ms cadence.
  2. Confidence Modeling: Calculates a score (0-100) based on block persistence.
  3. Soft Reorg Detection: Instantly alerts when a pre-confirmation is replaced.

🏮 Live Case Study (60s Baseline)

Captured from sepolia.unichain.org on April 13, 2026.

Timestamp            | Block #    | Confidence   | Status
------------------------------------------------------------
00:35:20.918         | 49184493   |      50.00% | PENDING

[!] ALERT: Soft Reorg Detected at Block 49184494!
00:35:22.304         | 49184494   |      50.00% | PENDING
00:35:22.741         | 49184495   |      75.00% | PENDING

[!] ALERT: Soft Reorg Detected at Block 49184496!
00:35:24.027         | 49184496   |      50.00% | PENDING
...

Key Finding: We detected 18 soft reorgs in 60 seconds. This proves that every user on Unichain is currently blind to a reorg happening on average every 3.3 seconds.

📍 Part 2: $60,000 Grant Proposal & Roadmap

Track: Unichain Foundation Infrastructure
Timeline: 6 Months (3 Milestones)
Deliverables: Indexer, API, and Public Dashboard.

🏮 The Problem: The "Visibility-Trust" Gap

Wallets cannot safely show a "Confirmed" checkmark to retail users in 200ms without knowing the probability of a revert. Professional LPs cannot protect their Uniswap v4 hook executions from silent drops. FlashStat bridge this gap.

🏮 Implementation Roadmap

Milestone 1: Production Indexer ($20,000 / Month 1-2)

  • Transition this POC into a production-grade Rust indexing service.
  • Launch a public GraphQL endpoint for historical soft-reorg analytics.

Milestone 2: Confidence API ($20,000 / Month 3-4)

  • Launch of the flash_getConfidence JSON-RPC API.
  • Implementation of the FlashConfidence Formula: Confidence = V(TEE) * (P^M) * D.

Milestone 3: flashstat.io Dashboard ($20,000 / Month 5-6)

  • Public-facing network health portal.
  • TEE Attestation: Real-time hardware-level verification of the Unichain sequencer via Intel TDX.

🏮 Ecosystem Impact

FlashStat turns Unichain's speed from a "risk" into a "trust factor." We enable wallets to confidently display sub-second transactions, directly increasing the safety and depth of liquidity on Uniswap v4.
