Story
Marca.eco is the public eco-certification registry of the Antiquantum.eco ecosystem, operated by Artificialss.ai. Our mission: make ecological work verifiable. Every land restoration, donor commitment, and stewardship action is anchored to a permanent, post-quantum-secured certificate on our public registry. By replacing self-reported sustainability with cryptographic proof, we end greenwashing and return 90% of the value generated to the people doing real ecological work on the ground.
