ProofCheck for ProofMode focuses on enabling authentication and verification of multimedia content directly on smartphones, indicating a strong user-centric design approach. The use of enhanced sensor-driven metadata, hardware fingerprinting, and cryptographic signing showcases functionality targeted at both activists and everyday users.

ProofMode contributes to the Web3 ecosystem by providing open-source tools for decentralized cryptographic provenance and authentication. The project's integration with IPFS/Filecoin networks and its plans to incorporate Ethereum-based capabilities further demonstrate a robust contribution to the Web3 landscape.

ProofMode offers a unique system for decentralized multimedia verification, which is differentiated from other tools that rely on corporate or private infrastructures. The use of open standards and the decentralized nature of the application underline its innovative approach to addressing the need for proof and chain-of-custody.

ProofMode adheres to open-source principles, contributing to and developing open-source software and integrating developer libraries into third-party tools. It has also shown ethical commitment by participating in human rights documentation tools and the Coalition for Content Provenance and Authentication (C2PA).
