\begin{abstract}
Distributed ledger technology (DLT) provides decentralized and
tamper-resistant data storage, replicated among mutually untrusting
participants. With the advancement of this technology, different
privacy-preserving blockchains have been proposed, such as Corda,
Hyperledger Fabric, and Digital Asset's Canton. These distributed
ledgers only provide \textbackslash{}emph\{partial consistency\}, which
implies that participants can view the same ledger differently.

A \textbackslash{}emph\{view\} represents the states of a blockchain
available to a particular stakeholder. The combination of views forms an
integrated view that represents a consistent global state shared by all
participants.

This paper introduces BUNGEE ~(Blockchain UNifier view GEnErator), the
first DLT view generator, to allow capturing DLT snapshots, constructing
views, and performing arbitrary operations on those, such as integrating
views. Creating and integrating views allows interesting applications,
such as stakeholder-centric snapshots for audits, cross-chain analysis,
blockchain migration, and data analytics.%
