Abstract: The invention comprises a method for registering of a digital document as a digital file in a blockchain database, in which database transactions are constructed of standard data containers which may have a fixed size, in a system comprising one or more storage nodes for storing at least part of the blockchain database, one or more approval nodes for approving transactions in said blockchain database and a first computer for generating transactions in said blockchain database, said computer having access to said blockchain database and having access to a first private key. The invention also comprises a computer program product comprising program code stored on a computer readable medium, said program code comprising computer instructions for performing said method.

Abstract: The invention is related to a method for secure transferring of information through a network between an origin Virtual Asset Service Provider and a destination Virtual Asset Service Provider, in a hostile environment, where every entity (party member, network node) must proof its entitlement of the information being exchanged. Hostile environment means that neither any entity/network node nor the network as a whole can be trusted. The present method doesn't require other party member/network node or database to secure information transfer. Neither it requires any other trusted entity or server to guarantee or provide proof of ownership of exchange information. The present method for communicating securely between electronic devices uses asymmetric key encryption. The invention comprises also a computer program product comprising program code stored on a non-transitory computer readable medium, said program code comprising computer instructions for performing the inventive method.
