Enabling Strong Database Integrity using Trusted Execution Environments

Understand

Many applications require the immutable and consistent sharing of data across organizational boundaries.

• Because conventional datastores cannot provide this functionality, blockchains have been proposed as one possible solution.
• Yet public blockchains are energy inefficient, hard to scale and suffer from limited throughput and high latencies, while permissioned blockchains depend on specially designated nodes, potentially leak meta-information, and also suffer from scale and performance bottlenecks.
• This paper presents CreDB, a datastore that provides blockchain-like guarantees of integrity using trusted execution environments.
