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 este o implementare de protocol și un nod blockchain care oferă un sistem de tranzacții confidențiale. Utilizează Pedersen Commitments și criptare homomorfă pentru a verifica integritatea valorii și a asigura o masă monetară consistentă fără a dezvălui sumele specifice ale tranzacțiilor sau identitățile participanților. Proiectul se remarcă printr-un model de schimb interactiv de tranzacții, unde portofelele coordonează schimburi de date în mai multe runde pentru a construi tranzacții semnate. Pentru a menține anonimatul, sistemul suportă livrarea tranzacțiilor prin onion-routing și maschează adresele IP de origine prin mecanisme de releu specializate. De asemenea, încorporează proof-of-work memory-hard pentru a rezista dominanței minării ASIC și utilizează un model de registru cu pruning de stare cu stocare Merkle Mountain Range pentru a reduce amprenta pe disc a blockchain-ului. Codul sursă acoperă un set larg de capabilități, inclusiv execuția de atomic swaps cross-chain trustless, gestionarea portofelelor deterministe ierarhice și operarea nodurilor de rețea complete. Oferă instrumente pentru minare limitată de memorie, execuția de contracte criptografice prin timelocks și comunicare securizată client-server folosind criptare autentificată. Nodul poate fi implementat ca o imagine de container cu suport pentru persistența datelor din cache.
Uses Pedersen commitments to hide transaction amounts while enabling homomorphic addition for balance verification.
Blitzar is a verifiable SQL proof engine and cryptographic library designed for verifiable SQL computation. It enables the execution of database queries off-chain while generating zero-knowledge proofs that certify the correctness of the results for on-chain verification. The project distinguishes itself through a GPU-accelerated proof accelerator that offloads heavy cryptographic workloads to graphics processors, reducing the time required for succinct proof generation. It provides high-performance cryptographic primitives for C++ and Rust applications, focusing on elliptic curve operations
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.
