What is the role of Hyperledger Quilt in relation to Hyperledger Sawtooth?

Hyperledger Quilt is designed specifically to facilitate interoperability between different blockchain networks. Its primary function is to enable the transfer of value and information across disparate blockchains, allowing for seamless communication and integration of multiple networks. This capability is essential in the blockchain ecosystem, where siloed networks can limit the potential for collaboration and the exchange of assets.

By connecting separate chains, Hyperledger Quilt leverages the Interledger protocol to allow transactions to occur across different ledgers, ensuring that users can engage with multiple blockchain networks without being constrained by the individual protocols of each network. This interoperability is crucial for organizations that require diverse solutions and want to maximize the utility of existing blockchain systems.

The other options do not accurately capture the role of Hyperledger Quilt. It does not serve as a consensus algorithm, nor does it provide a mobile framework or replace the need for a ledger itself. Hyperledger Quilt's unique function is primarily about bridging and linking different blockchain infrastructures, making it a vital component for enhancing the interconnectedness of blockchain technologies.
