Decentralized Global Digital Copyrights Asset Exchange System
DCAex.io is a decentralized global digital rights asset trading system with its headquarters located in Canada, aiming to provide such basic functional services as copyright protection, copyright trading, copyright retrieval, infringement monitoring, rights protection assistance, etc. for original creators with great commercial potential worldwide. Any organization or individual can use the trusted digital identity to publish digital creative works on DCAex.io and make them trusted, protected and sharable digital rights assets.
The "DCAex.io" block data is stored in a chain structure. All the blocks have a pointer reference to the previous block, to ensure that the data is not tampered with. The SHA-256 function is used to hash the file gene again, by ECC asymmetric encryption algorithm for authentication, AES encryption algorithm to encrypt the private key, and Merkle authentication and storage transactions.
The "DCAex.io" team has independently developed a file gene extraction and comparison technology that supports digital files in various formats like photo, video, audio and text, and can search 100 million photo galleries per second to ensure that the works are substantively tested and the file gene is encrypted into Blockchain books. Originators at home can enjoy 7 * 24 hours online copyright protection services.
Due to the large number of works and subjects involved in copyright transactions, and the nonidentity of originators and programmers, long-run availability of device connected to the blockchain can’t be guaranteed. So, "DCAex.io" did not adopt the typical PoW mechanism, but adopted a witness mechanism with reference to the DPoS mechanism. The witness can testify about the generated blocks.
