• cdbRegistry :: HKD f ( ResourceRegistry m)
• cdbGcDelay :: DiffTime
• cdbGcInterval :: DiffTime
• cdbBlocksToAddSize :: Word

  Size of the queue used to store asynchronously added blocks. This is the maximum number of blocks that could be kept in memory at the same time when the background thread processing the blocks can't keep up.

Fields

• hfbtBackoffDelay :: m BackoffDelay

  See BackoffDelay

• hfbtGetLedgerState :: STM m ( LedgerState blk)
• hfbtLedgerConfig :: LedgerConfig blk
• hfbtRegistry :: ResourceRegistry m
• hfbtSystemTime :: SystemTime m
• hfbtTracer :: Tracer m ( TraceBlockchainTimeEvent RelativeTime )
• hfbtMaxClockRewind :: NominalDiffTime

  Maximum time the clock can be rewound without throwing a fatal SystemClockMovedBack exception.

  When the slot length is short, e.g., Praos' 1s compared to PBFT's 20s, the chances of an NTP sync causing the clock to go back to the previous slot increase.

  We allow the system clock to rewind up to hfbtMaxClockRewind , tracing a TraceSystemClockMovedBack message in such cases. Note that the current slot *never decreases*, we just wait a bit longer in the same slot.
