Cryptographic commitments that allow the verification of sums without revealing the underlying values.
Distinct from Atomic Transactional Commits: Candidates are focused on version control 'commits' or database transactions, not cryptographic value commitments.

Monero is a privacy-focused cryptocurrency and proof-of-work blockchain designed for private digital payments. It utilizes a peer-to-peer network and a distributed ledger to allow users to send and receive currency while hiding transaction senders, receivers, and amounts. The system achieves financial confidentiality through the use of ring signatures for sender obfuscation and RingCT with Bulletproofs to hide transaction values. To ensure network security and decentralization, it employs a memory-hard proof-of-work algorithm optimized for general-purpose CPUs. The project provides a full no
Hides transaction values using cryptographic commitments that allow the network to verify balances privately.
Grin is a protocol implementation and blockchain node that provides a confidential transaction system. It uses Pedersen Commitments and homomorphic encryption to verify value integrity and ensure a consistent money supply without revealing specific transaction amounts or participant identities. The project distinguishes itself through an interactive transaction exchange model, where wallets coordinate multi-round data exchanges to build signed transactions. To maintain anonymity, the system supports onion-routed transaction delivery and masks originating IP addresses through specialized relay
Uses Pedersen commitments to hide transaction amounts while enabling homomorphic addition for balance verification.
Blitzar ist eine verifizierbare SQL-Proof-Engine und kryptografische Bibliothek, die für verifizierbare SQL-Berechnungen entwickelt wurde. Sie ermöglicht die Ausführung von Datenbankabfragen off-chain, während Zero-Knowledge-Proofs generiert werden, die die Korrektheit der Ergebnisse für die on-chain-Verifizierung zertifizieren. Das Projekt zeichnet sich durch einen GPU-beschleunigten Proof-Accelerator aus, der rechenintensive kryptografische Workloads auf Grafikprozessoren auslagert und so die für die Generierung prägnanter Proofs erforderliche Zeit reduziert. Es bietet hochperformante kryptografische Primitive für C++- und Rust-Anwendungen, mit Fokus auf elliptische Kurvenoperationen und Multi-Skalar-Multiplikation. Das System deckt eine breite Fläche an Datenmanagement und Sicherheit ab, einschließlich trustless Datenintegration, die Blockchain-Indizierung mit off-chain-Datensätzen zu manipulationssicheren relationalen Tabellen kombiniert. Es nutzt BFT-Konsens und Threshold-Signaturen zur Aufrechterhaltung der Statusintegrität, neben Mechanismen für Quorum-basierte Datensynchronisation und verifizierte Ergebniszustellung via Smart-Contract-Callbacks. Die Codebasis bietet native Bindings für C++ und Rust, um ihre kryptografischen Toolsets und Proof-Berechnungsbibliotheken offenzulegen.
Maintains shared state integrity by signing and committing updates to cryptographic data commitments.
Erigon is an Ethereum execution client and blockchain archive node designed to maintain full or archive copies of the blockchain. It functions as a Proof-of-Stake validator, an Ethereum RPC server, and a network validator operation tool, providing the core infrastructure to validate blocks and secure the chain. The project distinguishes itself through high-performance storage and data distribution, utilizing a flat key-value state storage system instead of a Merkle Patricia Trie to increase read and write speeds. It employs BitTorrent-based data distribution for immutable historical blockchai
Provides capabilities to regenerate and correct state commitment data within the database to ensure chain integrity.
