Publication number: 20220182221Abstract: Present-day blockchain architectures suffer from several problems, including poor extensibility and scalability. This may stem from tying two parts of the consensus architecture, namely canonicality and validity, too closely together. The Polkadot architecture, which is a heterogeneous multi-chain, provides better extensibility and scalability by setting canonicality and validity apart. Compartmentalizing canonicality and validity and keeping overall functionality to a minimum of security and transport introduces practical core extensibility in situ. Scalability is addressed through a divide-and-conquer approach to canonicality and validity, scaling out of its bonded core through the incentivization of untrusted public nodes. The heterogeneity of this architecture enables many highly divergent types of consensus systems interoperating in a trustless, fully decentralized “federation,” allowing open and closed networks to have trust-free access to each other.Type: ApplicationFiled: October 14, 2021Publication date: June 9, 2022Applicant: Parity Technologies Ltd.Inventors: Gavin Wood, Robert Habermeier

Patent number: 11132451Abstract: The decentralized and distributed architecture of blockchain makes it challenging to store secret data. A Secure Document Access Control System (SEDACS) can store secret data using distributed components without compromising on the distributed security features of the blockchain. SEDACS can include a Secret Store, a blockchain, and a decentralized file system. The blockchain can store rules and permissions for documents that contain the secret data. The Secret Store can generate secret keys that can be used to access the documents. The decentralized file system can store the documents that are encrypted using the secret keys. A user can retrieve the encrypted document provided that the user has the permission to do so. The user can decrypt the encrypted document by decrypting the secret key and using the decrypted secret key to decrypt the document.Type: GrantFiled: August 31, 2018Date of Patent: September 28, 2021Assignee: Parity Technologies Ltd.Inventors: Gavin Wood, Piotr Czaban, Sviatoslav Nikolskii, Kenneth Kappler, Nicolas Gotchac
