Our extensive evaluation of LineageChain demonstrates its benefits to the new class of blockchain applications, its high query performance and its small storage overhead.Ībadi, D. J., Arden, O., Nawab, F., Shadmon, M.: Anylog: a grand unification of the internet of things. We have implemented LineageChain on top of Fabric and a blockchain optimized storage system called ForkBase. LineageChain provides a novel skip list index designed for efficient provenance queries. LineageChain captures provenance during contract execution and stores it in a Merkle tree. LineageChain exposes lineage information to smart contracts runtime via simple and elegant interfaces that efficiently and securely support provenance-dependent contracts. We then present LineageChain, a fine-grained, secure and efficient provenance system for blockchains. We first motivate the need for adding native provenance support to blockchains. In this paper, we identify a new class of blockchain applications whose execution logics depend on provenance information at runtime.

This approach is applicable to large-scale, offline analysis, but is not suitable for online transaction processing. However, querying data history in existing blockchains can only be done by replaying all transactions. The management of that history, also known as data provenance or lineage, has been studied extensively in database systems.
The system captures the entire evolution history of the states. A blockchain system implements a tamper-evident ledger for recording transactions that modify some global states. The success of Bitcoin and other cryptocurrencies is drawing significant interest to blockchains.
