RegionFence proposes adaptive concurrency control mixing optimistic and pessimistic mechanisms for parallel smart-contract execution within blockchain blocks.

Most key-compromise defenses today (smart wallets, ERC-7579 modules, social recovery, EIP-7702 delegation) enforce policy in the account’s code. ERC-8403 continues this: spend limits and unlock times are authorities committed under the account’s root. I’d like to probe a…

Abstract PropAMMs are on-chain venues whose prices are set by a single maker. The maker Three of the registry venues accept maker state only if it is stamped with Takers pay about 0.45 bp at the fill, on every one of the 30 days. Over the Of fills after a CEX move of more than…

⚠️ Security: CVE-2026-98432 (Linux kernel) CVE-2026-98432 is a use-after-free in the Linux kernel's IPv4 TCP stack. It is not specific to MPTCP, but the demonstrated remote exploit requires an MPTCP listener, which Go 1.24+ enables by default. This release disables MPTCP…

Taxonomy of economic-state manipulation attacks in DeFi: 276 real incidents and 91 Code4rena findings analyzed to distinguish root causes from observable price distortions.

⚠️ Security: CVE-2026-98432 (Linux kernel) CVE-2026-98432 is a use-after-free in the Linux kernel's IPv4 TCP stack. It is not specific to MPTCP, but the demonstrated remote exploit requires an MPTCP listener, which Go 1.24+ enables by default. This release disables MPTCP…

Description: A canonical, content-addressed structure that any independent party (wallet, hardware device, second machine, third-party verifier) can produce and re-verify from the exact same VerificationPayload + state snapshot. It turns simulation from a trusted frontend…

Failure-mode taxonomy for Ethereum smart contracts categorizes observable deviations from intended behavior and ranks failures by impact severity.

Key takeaways Around 4:20 p.m. ET on October 29, 2026, funds began leaving Binance hot wallets across multiple blockchains. Unauthorized… The post The $6.4 Billion Binance Hack: Tracing the North Korea Link appeared first on Chainalysis.

Digital signatures control who can spend funds, issue commands and authorize requests. Widely used schemes rely on factoring or discrete logarithms, assumptions threatened by Shor’s quantum algorithm. The post-quantum transition therefore reaches the mechanism used to establish…
