Glance is a RAG method in which the generator also reranks. It adds a lightweight decision adapter and pointer head that score candidate passages from one shared prefill, so a single resident 9B backbone does generation and reranking. After 39 minutes of MS MARCO fine-tuning it reaches nDCG@10 of 0.741 on SciFact and 0.345 on NFCorpus, against 0.721 and 0.326 for bge-reranker-v2-m3. On 300 HotpotQA questions it improves answer F1 by 0.045 over cross-encoder-selected context. Evaluation covers two retrieval datasets, one QA dataset and one backbone family.

JevAct is a runtime verification framework that intercepts selected LLM agent actions before execution and returns feedback for bounded revision. It compiles domain policies into executable state checks and structured questions scored by a prefill-only decision model, giving probability-based judgments without generation. Tested on eleven agents with tau^2-bench Airline and Telecom and BFCL, it gained consistently on Telecom and BFCL and was mixed on Airline.

EnvSched is an online scheduler for agentic reinforcement learning that picks which environment-task pairs to roll out next. It builds a dual-relation graph over environments and tasks, propagates past rollout statistics to predict within-task reward variance, and adds environment quotas and a similarity penalty. On Qwen3-8B it scores 48.81 average on BFCL-v3, tau-Bench and ACEBench-Agent after 40 steps, above random selection at 120 steps.

Dutch police arrested two men, aged 23 and 25 from Vaassen and Ede, on October 6 over a bank helpdesk fraud that took over €380,000 from 170 victims. Callers played AI-generated bank audio, then a fake bank employee had victims install an app and tap their card to the phone. The app read the NFC chip data and relayed it to an accomplice at an ATM. Police seized the servers.

IFC-MCQ is a method that automatically generates multiple-choice benchmarks from Industry Foundation Classes (IFC) building-model files, so answers can be graded by exact option-set match instead of human or LLM review. Its taxonomy has 15 categories and 36 subtypes in four groups, with answer keys from the file and distractors from file values or rules. Two agentic setups, tool-based and code-based retrieval, showed category-specific failures and variation by IFC model and interface.

A X thread benchmarking Qwen3.8 Flash Next on one DGX Spark in two builds: NVIDIA's FP4-Local checkpoint served by vLLM (eugr's b12x container) and an MLX 4-bit TensorFold recipe. The NVIDIA build scores higher on the author's agentic benchmark (81.2 vs 75.0), BFCL tool calling (82.4 vs 71.8 single-turn, 54.5 vs 43.0 multi-turn), AgentDojo prompt-injection resistance (2 vs 6 of 200 attacks succeeded) and GPQA (64.6 vs 59.1). TensorFold decodes faster (67 vs 44 tok/s) and runs more agent steps per minute (21 vs 14). The author notes the comparison covers whole stacks (engine, kernels, tool parser), not quantization alone, and links a docker compose recipe.

Draft ERC from Quantova Inc proposing a "Quantum Bridge Shield" for Ethereum bridges. A committee signs the Merkle root of each message batch with RFC 8554 LMS hash-based signatures instead of ECDSA/BLS keys that Shor's algorithm can break. The guard contract requires a strict majority of distinct unfrozen keys, records used leaves, freezes any key that signs a leaf twice, binds digests to domain, chain, guard and epoch, and applies a 60-second delay. The post gives gas costs (LMS W4 height-10 verification about 205k gas, a LayerZero packet 128,683 gas, worst-case rotation 12.44M gas under the EIP-7825 cap) and cites a NioLabs assessment with no critical or high findings. It is relevant as a worked post-quantum migration design for bridge key custody, including hybrid ECDSA+LMS mode and stateful-signature pitfalls such as leaf reuse and rollback.

Draft ERC from Quantova Inc that has Ethereum bridges accept cross-chain message batches only when a committee signs the Merkle root with RFC 8554 LMS hash-based signatures. The guard contract requires a strict majority of distinct unfrozen keys, records used leaves, freezes any key that signs a leaf twice, binds digests to domain tag, chain ID, guard address and epoch, and enforces a 60-second delay. It reports gas benchmarks (about 205k per LMS W4 height-10 verify, 12.44M worst-case rotation under EIP-7825), a hybrid LMS+ECDSA migration mode, and a NioLabs assessment with no critical or high findings. It argues that Shor's algorithm makes secp256k1 and BLS committee keys a quantum theft target.

Official changelog for the Model Context Protocol 2026-07-28 specification. Major changes: protocol-level sessions and the initialize handshake are removed to make MCP stateless, with version and capabilities carried in _meta on every request, plus a new server/discover RPC and subscriptions/listen replacing the GET stream and resource subscribe calls. It introduces Multi Round-Trip Requests (InputRequiredResult) in place of server-initiated sampling, roots and elicitation requests, moves tasks into an extension, and deprecates Roots, Sampling, Logging, HTTP+SSE and Dynamic Client Registration. Minor changes add cache hints (ttlMs/cacheScope), new Mcp-Method/Mcp-Name headers, OpenTelemetry trace context, RFC 9207 iss validation and an error-code allocation policy.

A tweet describing an independent open-source project, "Free Claude Code", that lets Claude Code run against non-Anthropic providers such as DeepSeek and Kimi. It supports switching models, configuring fallback providers and using providers' free tiers, launched via `fcc-claude` from the terminal or an IDE. It states the limits: free usage follows provider quotas, some providers still need API keys, it does not unlock Anthropic's own models, and it is not affiliated with Anthropic. The page also shows a quoted article on a 5-layer setup for running coding agents in YOLO/auto-approve mode safely.

Uber's engineering team describes how it extended its Zero Trust stack to give AI agents verifiable identities. Each agent workload gets a SPIRE SVID, and a Security Token Service checks an Agent Registry and mints single-hop, short-lived JWTs. Those tokens carry the full actor chain (for example user → Oncall Agent → Investigation Agent), loosely modelled on OAuth 2.0 Token Exchange (RFC 8693). The tokens are enforced at an MCP Gateway for tool calls, and an AI Gateway fronts model calls with guardrails. The post also covers an A2A client in the SDK that makes the secure path the default, observability of actor chains, and a 2026 roadmap toward dynamic access control and unified policy enforcement. It is a concrete production reference for agent attribution and delegated authorization.

The UK FCDO sanctioned crypto exchange Cryptomus via its Vancouver registered owner Xeltox Enterprises and linked platform Heleket, Kyrgyz firms TokenSpot and Tsunami Payments, and payment processor Processing KG which operates VexPay and is owned by Kyrgyzstan's Ministry of Finance, plus its director Ulan Bukabaev, for allegedly helping Russia evade financial sanctions. Two of the designated entities reportedly processed transactions for the Kremlin backed A7 illicit finance network, which claims to have moved over 90 billion dollars last year, roughly half of Russia's annual military spending. The 38 target package, which also hit oil producers Zarubezhneft and INK Capital and 12 shadow fleet tankers, follows earlier UK and EU action against Justin Sun's HTX and extends a pattern of Western sanctions targeting crypto rails used for Russia sanctions evasion.

Vitalik Buterin responds to Ethereum Foundation researcher Justin Drake's bunker mode proposal, agreeing AI-accelerated cryptanalysis could break ECDSA, the signature scheme behind most crypto wallets, in months not years, and that lattice-based schemes like ML-DSA billed as quantum-safe could also take serious hits within two years. Buterin gives practical key-hygiene advice such as keeping funds in addresses that never exposed a public key and rotating multisig signer keys after every operation with offchain signature collection, while warning that botched migrations cost more than hacks.

An IACR ePrint paper benchmarks whether running the classical and post-quantum components of hybrid TLS 1.3 key exchange (ECDHE–ML-KEM) and Composite ML-DSA signatures in parallel on separate pthread worker threads reduces handshake latency versus sequential execution. Across three RFC 10024 ECDHE–ML-KEM groups with server and mutual authentication, parallelism sped up all six tested conditions on a standard ARM and x86 system (1.04×–1.28×), with the largest gains in signature stages where component times are balanced, but slowed every condition on a low-power x86 system (0.80×–0.92×) because thread wake/wait overhead outweighed savings. The authors conclude that component independence alone doesn't guarantee a speedup and that parallelization decisions must be validated per target environment.

Victor Shoup shows that "reconstruct-later" asynchronous verifiable information dispersal (AVID) designs — used by data-availability systems including an early Walrus design/testnet — are insecure when built on the standardized Raptor codes R10 (RFC 5053) and RaptorQ (RFC 6330). Using the Plotkin bound, he proves that a Byzantine disperser can choose a subset of f+1 honest fragments that fails to reconstruct the message, gives randomized polynomial-time algorithms to find such subsets, and implements a working attack that defeats an RFC 6330 RaptorQ decoder on every adversarial subset tested (success for f from 9 to 45). Benchmarks show plain Reed-Solomon coding is an MDS alternative that is often faster and never much slower than R10/RaptorQ, making it the safer practical choice for this design pattern.

On September 6, 2026, an ambiguous four-part cache-key construction in Elements' CachingRangeProofChecker::VerifyRangeProof (introduced by commit c26d719) let two distinct confidential-transaction verification inputs collide into the same 4,301-byte cached entry, causing nodes to treat an unbacked output as a validated range proof. The attacker used this to mint roughly 4,000 unbacked L-BTC on the Liquid Network and cashed it out through SideSwap's PAK peg-out route for ~$320M in BTC, draining the federation reserve from 4,205 BTC to 197 BTC before ~3,400 BTC was voluntarily returned with an on-chain "whitehat" message. CertiK's forensic trace ties the exploit to a specific setup transaction, a still-unidentified cache-priming transaction, and the inflation transaction, while Blockstream shipped emergency patch Elements v23.3.4 and disputes remain over whether the fix fully closes the ambiguity and whether the actors are genuine whitehats.

Nuvex is a Solana-native verifiable compute and oracle protocol, still pre-mainnet, whose own README documents unresolved security gaps instead of hiding them: its VRF proof verification relies on solana-ecvrf 0.0.1 (RFC 9381 ECVRF-Edwards25519-SHA512-TAI) which has no known audit, max_fee is stored but never actually charged, and VRF fulfillment is first-come among any node meeting the configured stake/heartbeat threshold — meaning an operator who funds several keys at a low minimum stake can selectively pick which randomness output gets used. The deploy-mainnet script is stubbed to exit before any transaction, and unresolved design questions (fee shares, challenge/reject state transitions) are tracked as explicitly blocked ADRs rather than quietly shipped.

SmartMemory is an academic framework that detects "OFC inconsistency" (OFCI) — a newly identified root-cause vulnerability class where business-logic flaws break the equivalence between a smart contract's on-chain state and its off-chain counterpart, affecting cross-chain bridges, real-world-asset tokenization, and fiat-backed stablecoins. It normalizes heterogeneous on-chain/off-chain implementations into a canonical business-semantic representation, uses a memory-based agent to distill and reuse vulnerability patterns across cases, and verifies candidates with taint analysis. Evaluated on a new dataset of 48 DApps with 81 known OFCIs (80.68% precision, 87.65% recall), it also found 36 previously unknown, since-fixed OFCIs in an analysis of 325 real-world OFC applications.
