With more and more applications built on top of blockchains, there is an increasing need of searching the data stored in a blockchain database. To ensure query integrity, a user can maintain the entire blockchain database and search the data locally. However, this approach is not economic, if not infeasible, because of the blockchain’s huge data size and considerable maintenance costs. In this talk, we present some of our recent efforts towards index-based and integrity-assured search in blockchain systems. |
