Answers

Answer 1: Distributed ledger technology (DLT) is a system that replicates and synchronizes data across multiple nodes or computer networks. Characteristics of DLT networks include decentralized control, transparency, security, and immutability.

Answer 2: The DLT synchronization system discussed in this article aims to address the lack of interoperability between different DLT platforms, thereby enabling seamless data sharing and synchronization across DLT networks.

Answer 3: An interoperability node acts as a bridge between different DLT networks, facilitating communication and data exchange between them. It can access and modify the blockchain on the connected DLT network, acting as a trusted middleman.

Answer 4: An exchange node is a full node in a DLT network, responsible for initiating and confirming synchronization with an interoperability node. On the other hand, a portal interface acts as a communication interface between exchange nodes and interoperability nodes, simplifying the interaction between them.

Answer 5: A DLT object refers to a collection of data stored on a blockchain, which can be tokenized or non-tokenized. Examples include programmable assets (e.g., smart contracts), datasets, and even metadata associated with digital assets.

Answer 6: Programmable assets can be either sequence-independent or sequence-dependent. The output of sequence-independent assets is not affected by the order in which operations are performed, whereas the state of sequence-dependent assets depends on the order of events.

Answer 7: The synchronization repository maintains the active state of DLT objects, transition logic, synchronization proposals and agreements, trusted entity agreements, and synchronization history across different DLT networks.

Answer 8: The trusted entity agreement establishes a mutually trusted relationship between participating DLT networks, allowing interoperability nodes to access and modify their blockchains for synchronization.

Answer 9: A synchronization proposal is initiated by an exchange node in one DLT network, requesting synchronization with another network. The exchange node in the target network issues a synchronization confirmation to authorize the synchronization process.

Answer 10: DOS resolves update conflicts by giving priority to the latest block timestamp containing DLT object modifications. If the timestamps are the same, the DLT network with the unlocked version of the DLT object will be given priority.

Glossary

Term Definitions Active State Synchronization A synchronization method in which DLT networks communicate their latest state to each other immediately after any update or change is made. Blockchain A growing list of records, called blocks, that are linked and secured using cryptography. Consensus The process by which nodes in a distributed network agree on a single state of shared data. Distributed Ledger Technology (DLT) A system that replicates and synchronizes data between multiple nodes or computer networks. DLT object is a collection of data stored on a blockchain and can be either tokenized or non-tokenized. DLT Object Synchronizer (DOS) A system component responsible for synchronizing DLT objects across different DLT networks. Exchange Node A full node in a DLT network that is responsible for initiating and confirming synchronization with an interoperability node. An interoperability node acts as a bridge between different DLT networks, facilitating communication and data exchange between them. Portal Interface acts as a communication interface between exchange nodes and interoperability nodes, simplifying the interaction between them. Programmable Asset A DLT object type containing code or scripts executed in a DLT network, such as a smart contract. Synchronization Repository A database that stores information related to DLT object synchronization, such as transformation logic, synchronization status, and trusted entity protocol. Trusted Entity Protocol A protocol that establishes a mutually trusted relationship between participating DLT networks, allowing interoperability nodes to access and modify their blockchains for synchronization. Target blockchain The blockchain that will receive the synchronized DLT object. Target DLT Network A DLT network containing the target blockchain.
