Our company is a permanent arbitration court registered in London, U.K., resolving commercial disputes on-line - using electronic documents. We use current international law, in particular the UN Convention on Recognition and Enforcement of Foreign Arbitral Awards, as a "proxy" between a cryptography tools and national legal systems in different countries. We build an international self-expanding network of notaries accredited by the arbitration court for purpose of identification of individuals and legal entities, verification public OpenPGP keys (for signing and/or encrypting documents) and certification of documents. We have a web server www.cryptonomica.net which connects the customers, notaries and the arbitrators and holds information about public keys and verifications. From our web-site signatures or document hashes can be stored on Ethereum blockchain in special smart-contract. Verified keys are also used as identity proof for accounts on Ethereum blockchain, for this we have another smart-contract deployed on the Ethereum blockchain. Our web-site, our server with blockchain node, our smart-contracts are open sourced, code on https://github.com/Cryptonomica We have developed a legal model allowing to legitimately working with cryptography even in problematic jurisdictions without the requirement to be licensed as a certification center or licensing of software. Hence, we can develop the network in different countries and do it fast.
