There Is No Patch Tuesday on the Blockchain: Why Solidity Developers Need Fusion-Grade AppSec Before They Deploy
Checkmarx argues Solidity developers need pre-deployment AppSec because disclosure-to-weaponization time has collapsed from 840 days to 1.6 days.
A Checkmarx write-up contrasts traditional software patch cycles with blockchain development, where there is no Patch Tuesday and fixes require on-chain upgrades. It cites stats that median disclosure-to-weaponization time collapsed from 840 days to 1.6 days and that 80% of exploitations now occur on or before disclosure day. The piece advocates fusion-grade application security for Solidity teams before contracts deploy.
CertiFlash: A Formal Verification Framework for Flash Translation Layers in Computational Solid State Drives
CertiFlash provides machine-checked formal verification of SSD flash translation layers, proving isolation, integrity, and ownership invariants to prevent tenant data leaks.
CertiFlash is an open-source formal verification framework for Flash Translation Layers (FTL) in computational SSDs, mechanized in the Rocq proof assistant. It shows that a faulty FTL can corrupt device state at five surfaces (e.g., leaking data between tenants or dropping integrity tags), demonstrated on a DaisyPlus OpenSSD. Designers prove once that every operation of a general FTL model preserves a global invariant covering mapping, isolation, integrity, ownership, and allocation; new designs need only discharge five hypotheses. Across four case studies, added effort was 27-3,231 lines against a 16,489-line framework.
IntentFuzz: A Protocol-Aware Fuzzer for Automated Invariant Violation Detection in Intent-Based Cross-Chain Bridges
IntentFuzz protocol-aware fuzzer recovers bridge structure from unannotated Solidity and confirmed 22 invariant violations across 24 real-world deployments.
IntentFuzz formalizes a taxonomy separating invariant violations from settlement exposures in intent-based cross-chain bridges, then recovers a bridge's intent structure and deposit/fill function roles from unannotated Solidity source. It classified deposit and fill functions with 100% recall and 82% combined precision, and achieved 100% recall and precision on 23 planted-bug mutants. Across 24 real-world deployments it confirmed 17 genuine invariant violations with heuristic-only input generation, rising to 22 with its LLM-assisted tier, spanning eight vulnerable GitHub repositories with findings reproducible against public deployed bytecode.
