BlockChainConstruction

Prefazione In questo articolo introduciamo principalmente diversi aspetti dell'audit delle public chain che meritano attenzione. Per gli auditor di sicurezza e gli sviluppatori di public chain, questo è un progetto degno di riferimento e di riflessione. Architettura Prima di introdurre la...

LLM Council — Validazione delle evidenze VAPT Una pipeline di peer-review cieca che convalida un'evidenza di penetration test prima che arrivi al cliente. Lenti esperte indipendenti valutano l'evidenza, si sottopongono a revisione cieca l'una con l'altra, e un Presidente sintetizza un verdetto...

EUVD-2026-63665

tor before 0.4.9.9 was prone to an out-of-bounds write when parsing a consensus or detached signature with unexpected signature digest type. Impact is minor for most Tor roles, but potentially major for directory authorities. This is TROVE-2026-019...

CVE-2026-52738

ZEBRA is a Zcash node written entirely in Rust. Prior to 4.5.0, a consensus-valid block containing a long chain of transparent self-spends to one address can permanently halt Zebra nodes. In zebra-state/src/service/finalizedstate/zebradb/transparent.rs, the finalized-state writer originally appli...

CVE-2026-52738

Zebra (a Zcash node written in Rust) versions up to v4.4.1 are vulnerable to a persistent chain halt . The finalized-state writer in transparent.rs applies all credits before debits within a block, so a consensus-valid block with a long chain of transparent self-spends to one address can push the...

CVE-2026-52735 ZEBRA: Consensus divergence via P2SH sigop undercount in pure-Rust disabled-opcode parser

ZEBRA is a Zcash node written entirely in Rust. Prior to 4.5.0, Zebra can accept a block that zcashd rejects because the P2SH signature-operation counter undercounts redeem scripts containing a disabled opcode followed by signature opcodes. In zebra-script/src/lib.rs, p2shinputsigopcount used the...

CVE-2026-52735

Zebra (a Rust-based Zcash node) used a pure-Rust P2SH sigop counter that short-circuited on disabled opcodes like OP_CODESEPARATOR, undercounting sigops compared to zcashd. An attacker without mining power could trigger a chain split by broadcasting P2SH spends with malicious redeem scripts. Fixe...

CVE-2026-58262

Klever-Go is the Go implementation of the Klever blockchain protocol. Prior to 1.7.20, header signature verification counts the unused padding bits of the PubKeysBitmap toward the two-thirds validator quorum. These padding bits do not correspond to any validator and are ignored by the actual BLS...
