NIP-XX

Content Rendering Guidelines

draft optional

This NIP defines standard guidelines for how clients SHOULD detect and render inline media URLs and other embeddable content within event .content fields. The goal is to provide a consistent user experience across different Nostr clients.

CVE-20XX-XXXX: Bitcoin Core OP_RETURN Arbitrary Data Exposure via Self-Rendering Payloads

Summary

Bitcoin Core v30 and later relay, index, and expose up to 100,000 bytes of arbitrary OP_RETURN data by default. When an attacker embeds a self-rendering Data URI (e.g., data:image/*;base64,…) inside an OP_RETURN output, Bitcoin Core stores the content and makes it accessible through standard JSON-RPC and REST interfaces. Any client retrieving the transaction through these interfaces receives the Data URI in cleartext, which can be immediately rendered by a web browser or other HTTP-capable software without specialized tooling.

This behavior may unintentionally cause node operators to store, retrieve, or serve content that is harmful, illegal, or high-risk, creating operational, security, and legal exposure for downstream systems.

Vulnerability Type

RGB Contract Encoding and Commitment Analysis

Executive Summary

This document provides a detailed analysis of how RGB Non-Inflatable Assets (NIA) are encoded, hashed, and committed to Bitcoin using the RGB protocol. The analysis is based on the issue_nia::case_1 test executi on.

Test Parameters

Baid64 Specification

Overview

Baid64 (Base64 Aided Identities) is an enhanced Base64 encoding scheme designed for secure, human-verifiable identity encoding. It extends standard Base64 with Human Readable Identifiers (HRI), cryptographic check sums, mnemonic representations, and optional formatting features to create a robust encoding system suitable for identity management and secure data representation.

2 Introduction

The Linked Web Storage (LWS) Protocol defines the minimum set of interoperable, HTTP-based interactions that let any conforming application read, write, and manage data that lives outside the application’s own infrastructure. Its purpose is to restore an essential architectural principle of the Web: users control where their data is stored while applications come and go—without breaking links, permissions, or provenance.

Today most Web applications entangle storage, identity, access control, and business logic behind a single origin. Migrating to a new provider or adopting a new application therefore often means abandoning existing data. LWS breaks that coupling. By standardising a small, resource-oriented contract it enables

portable personal and enterprise data vaults that can move between providers, clouds, or on-premise deployments,
application innovation decoupled from storage choices,
consistent security semantics across heterogeneous back-ends, and

LocalStorage Dump (LSD) Specification

Editor’s Draft — 4 May 2025

This document is an Editor’s Draft for discussion within the W3C Linked Web Storage (LWS) Working Group. It proposes LocalStorage Dump (LSD) — a lightweight convention and protocol profile that enables Web applications to serialise window.localStorage and persist the resulting data in any user‑chosen Linked Web Storage–compatible backend (e.g., Solid Pods, remoteStorage/Unhosted, WebDAV, nosdav).

Design principle: Per‑origin, per‑user, format‑agnostic, backend‑agnostic, privacy‑preserving.
