I doubt very much that you implemented a proper command log with truncation and rollback for leaders and followers, a state machine, leader election with voting, epochs, timeouts with smart backoffs, pipelining, async transport servers and clients with object serialization, quorums, initialization and discovery, persistent state, graceful shutdown, adding and removing members, a proper event queue, snapshots, and proper distributed testing. You can build a toy implementation in a weekend if you have a cookbook. A production-ready implementation takes a bit more.
