                Hyperledger announced Ursa, a modular cryptography software library meant to ease the development and interoperability of blockchains.
                <p dir="ltr">The <a href="https://cointelegraph.com/tags/hyperledger">Hyperledger</a> Technical Steering Committee has approved the Ursa project, a modular <a href="https://cointelegraph.com/tags/cryptography">cryptography</a> software library, according to an official <a href="https://www.hyperledger.org/blog/2018/12/04/welcome-hyperledger-ursa" rel="nofollow,noopener" target="_blank">announcement</a> Dec. 4.</p><p dir="ltr">According to the statement, as Hyperledger has matured, projects &ldquo;have started to find a need for sophisticated cryptographic implementations.&rdquo; The post describes Ursa as a shift from having each project implementing its own protocols to collaborating on a shared library.</p><p dir="ltr">Ursa is meant to avoid wasted work on duplicate projects, enhancing security by simplifying analysis and making it &ldquo;less likely for less experienced people to create their own less secure implementations.&rdquo;</p><p dir="ltr">Furthermore, the project is supposed to grant &ldquo;the ability to enforce expert review of all cryptographic code&rdquo; and simplify cross-platform interoperability since multiple projects would use the same libraries.<br>Hyperledger states that with the new library &ldquo;blockchain developers can choose and modify their cryptographic schemes with a simple configuration file.&rdquo; Also, Ursa will purportedly have &ldquo;implementations of newer, fancier cryptography.&rdquo;</p><p dir="ltr">The library is divided into two, smaller libraries. The first contains simple, standardized, modular cryptographic algorithms and the second one &ldquo;more exotic cryptography.&rdquo; Advanced cryptographic algorithms like pairing-based signatures, SNARKs, aggregate signatures, and threshold signatures are cited as examples.</p><p dir="ltr">Software will be primarily written in Rust, but will have &ldquo;interfaces in all of the different languages that are commonly used throughout Hyperledger.&rdquo;</p><p dir="ltr">Hyperledger expects that Ursa will ease development since &ldquo;it is easier for new projects to get off the ground if they have easy access to well-implemented, modular cryptographic abstractions.&rdquo;</p><p dir="ltr">Hyperledger is increasingly popular for institutional and commercial use. As Cointelegraph previously <a href="https://cointelegraph.com/news/russia-sberbank-and-interros-group-conclude-blockchain-based-foreign-exchange-repo-deal">reported</a>, major Russian bank <a href="https://cointelegraph.com/tags/sberbank">Sberbank</a> recently concluded an over-the-counter <a href="https://cointelegraph.com/tags/otc">OTC</a> foreign <a href="https://cointelegraph.com/tags/exchange">exchange</a> repurchase agreement by employing <a href="https://cointelegraph.com/tags/smart-contracts">smart contracts</a> on the Hyperledger Fabric Platform.</p><p dir="ltr">In November, French retail giant Carrefour <a href="https://cointelegraph.com/news/retail-giant-carrefour-launches-blockchain-food-tracking-platform-for-poultry-in-spain">deployed</a> a food tracking platform based on Hyperledger in its Spanish network. The system will be used to track free-range chickens raised without antibiotics.
