This paper analyzes Nostr’s relay-centric architecture, key management, and threat models, highlighting privacy limitations and proposing practical enhancements to bolster censorship resistance and anonymity.
Double spend is when a digital currency is spent twice. This piece explains how it happens, why blockchain prevents it, common attack methods, and defenses like confirmations and consensus.
Nostr clients combine a relay-based architecture with end-to-end cryptographic key management; this analysis assesses client design, key handling, privacy trade-offs, threat models, and mitigations to bolster censorship resistance.
A brain-wallet uses a memorized passphrase to generate a crypto private key. While simple, it’s vulnerable to weak passwords, brute-force attacks and loss of recall-experts advise deterministic wallets (BIP39) or hardware keys instead.
This article examines Nostr’s decentralized architecture, key-management model, and messaging protocols, evaluating security properties, privacy trade-offs, and implications for resilient, censorship‑resistant communication.
Examines Nostr’s relay-based architecture, cryptographic key management, and threat models, identifying privacy limitations and proposing practical enhancements to improve censorship resistance and anonymity.
This study examines Nostr’s decentralized design, key management, and messaging protocols, evaluating security properties, privacy trade-offs, and implications for resilient, censorship-resistant communication.
Nostr Protocol presents a minimalist, decentralized messaging architecture prioritizing security and user-controlled keys, enabling censorship resistance, end-to-end encryption, and enhanced privacy.
Proof of Work (PoW) is a consensus mechanism where miners solve cryptographic puzzles to validate transactions and secure blockchains. This guide explains how PoW works, its energy implications and trade-offs.
This paper examines Nostr’s decentralized relay model, key management, and threat surface, identifying privacy and censorship risks and proposing cryptographic and architectural mitigations to strengthen resilience.
