As Blockchain-as-a-Service (BaaS) has witnessed a growing interest in enterprises, many BaaS providers have emerged. However, current BaaS providers can pose a potential security threat in the context of a centralized service provider and clients that depend on the provider. We present Codit, collaborative auditing for BaaS. Codit is a consensus framework used by clients for detecting faulty behaviors of malicious BaaS providers. Codit employs a prefix agreement that allows clients to reach consensus on a common prefix of a blockchain by sharing analysis results of blocks received from the provider.

Byzantine fault tolerant (BFT) protocols have previously been developed mainly in C or Java. C offers high performance but is more error-prone, leading to more potential Byzantine faults, whereas Java offers memory safety at the cost of performance. The Rust programming language combines the performance advantages of C with safe memory management, and newer releases now enable the implementation of complex, non-blocking asynchronous frameworks, as is needed for efficient BFT frameworks. We present a BFT framework implementation in Rust and preliminary performance evaluations for the PBFT protocol.
