What Changed

I added a new job called Meeseeker::WitnessScheduleJob that will publish to a channel called steem:witness:schedule. Roughly every 63 seconds, when a new schedule is created by the blockchain, this channel will trigger an event.

Under the hood, you can see we're requesting the witness schedule from the API.

After a few checks to make sure we're not processing the next schedule too early, we publish the schedule to the steem:witness:schedule channel and continue to the next schedule.

This is a separate process from the normal meeseeker sync. I've updated the README.md file to include the following:

Witness Schedule

When running meeseeker witness:schedule, the steem:witness:schedule channel is available. This is offered as a separate command because most applications don't need to worry about this level of blockchain logistics.

For example, from redis-cli, if we wanted to subscribe to the witness schedule:

$ redis-cli
127.0.0.1:6379> subscribe steem:witness:schedule
