Abstract: Systems and methods are provided for generating a combined receipt in a distributed ledger system implemented by replicas of a network. The replicas maintain a distributed ledger comprising a plurality of executed transactions authenticated using a hash tree having a hash root. Some or all of the replicas cryptographically sign the hash root. A combined receipt for a first transaction and second transaction of a plurality of executed transactions is generated by determining path information comprising a minimum set of values required to generate the hash root from either the first transaction or the second transaction given the first transaction and the second transaction. The combined receipt for the first and second transactions comprises: i) the determined path information; and ii) signatures of one or more of the replicas which signed the hash root.

Abstract: An apparatus in one embodiment includes a first processing device configured to communicate over a network with one or more additional processing devices including at least a second processing device. The first processing device includes a first blockchain client and a first trusted execution environment, and is configured to establish a first payment channel with a second trusted execution environment of the second processing device. The first processing device is also configured to associate at least one deposit with the first payment channel through execution of a corresponding blockchain transaction via the first blockchain client. The first processing device is further configured to utilize the deposit associated with the first payment channel to carry out multiple off-blockchain transactions between the first processing device and at least the second processing device.
