The Exploratory System Laboratory aims at Making Permissioned Blockchain Systems Fast Again.

ResilientDB makes system-centric design decisions by adopting a multi-thread architecture that encompasses deep-pipelines. Further, we separate the ordering of client transactions from their execution, which allows us to perform out-of-order processing of messages.

  1. ResilientDB supports a Dockerized implementation, which allows specifying the number of clients and replicas.

  2. PBFT [Castro and Liskov, 1998] protocol is used to achieve consensus among the replicas.

  3. ResilientDB expects minimum 3f+1 replicas, where f is the maximum number of byzantine (or malicious) replicas.

  4. ReslientDB designates one of its replicas as the primary (replicas with identifier 0), which is also responsible for initiating the consensus.

  5. At present, each client only sends YCSB-style transactions for processing, to the primary.

  6. Each client transaction has an associated transaction manager, which stores all the data related to the transaction.

  7. Depending on the type of replica (primary or non-primary), we associate different a number of threads and queues with each replica.

  8. ResilientDB allows easy implementation of Smart Contracts. At present, we provide a comprehensive implementation of Banking Smart Contracts.

  9. To facilitate data storage and persistence, ResilientDB provides support for an in-memory key-value store. Further, users can take advantage of SQL query execution through > the fully-integrated APIs for SQLite.

  10. With ResilientDB we also provide a seamless GUI display. This display generates a status log and also accesses Grafana to plot the results. Further details regarding the > setup 1. of GUI display are available in the dashboard folder.
