In two years since the introduction of Hyperledger Indy in 2017, the scope of work within its development community has far extended beyond what was initially set in its proposal. To clarify and keep track of new and existing peer-to-peer interaction code for secrets management, verifiable information exchange, and secure messaging across different blockchains and other distributed ledger technologies, Hyperledger Aries was set in motion.
During a self-sovereign identity (SSI) webinar in June 2019, Nathan Georgeof the Sovrin Foundation explained how Aries stemmed from the Hyperledger Indy project to embrace non-blockchain components of a decentralized identity platform. By focusing on the information exchange, Aries looks to provide an infrastructure of tools for enabling data exchange, peer-to-peer messaging, and facilitating interactions between different distributed ledger technologies while remaining blockchain-agnostic.
