TL;DR: A good tool is and ought to be invisible—striving to make such tools is the goal of a toolmaker.One habit I see a lot, and have to push back on, is taking a tool's shortcomings and reselling them as a "puzzle game" which is "fun" to solve.I don't want my tools to be "fun". I want my tools to be invisible.Text Editor WarsLet's take vim as an example  This is just an example, and applies to other editors too..

Traceability in supply chains is a growing security concern. While Verifiable Data Structures (VDSs) have addressed specific issues, such as equivocation over digital certificates, they lack a universal architecture for all supply chains. This document defines such an architecture for single-issuer signed statement transparency. It ensures extensibility and interoperability between different transparency services as well as compliance with various auditing procedures and regulatory requirements.

CBOR Object Signing and Encryption (COSE) Receipts prove properties of a Verifiable Data Structure (VDS) to a verifier. VDSs and associated Proof Types enable security properties, such as minimal disclosure, transparency, and non-equivocation. Transparency helps maintain trust over time and has been applied to certificates, end-to-end encrypted messaging systems, and supply chain security. This specification enables concise transparency-oriented systems by building on Concise Binary Object Representation (CBOR) and COSE. The extensibility of the approach is demonstrated by providing CBOR encodings for Merkle inclusion and consistency proofs.
