VSL Reconcile

VSL Reconcile serves as an external state management tool for OP sequencers. It automatically transitions from an unhealthy sequencer to a backup sequencer to minimize downtime.

Environment Variables

SEQUENCERS_LIST

SEQUENCERS_LIST is the comma-separated sequencer list for OP nodes:

http://sequencer-1:9545,http://sequencer-2:9545,http://sequencer-3:9545

We recommend using internal DNS for discovering sequencers.

CHECK_INTERVAL

CHECK_INTERVAL is the interval between heartbeat checks. Default: 60s.

MAX_BLOCK_TIME

MAX_BLOCK_TIME is the maximum amount of block time tolerated before a sequencer is deemed unhealthy. Default: 5m. Must be longer than CHECK_INTERVAL. Should the sequencer be unable to produce a block for a duration exceeding MAX_BLOCK_TIME, Reconcile will automatically switch to a backup sequencer listed in the SEQUENCERS_LIST.
