Challenge

The most straightforward approach would be to subscribe to new blocks of a blockchain and use that as trigger for the lifecycle. However, this increases complexity and reduces control over the flow if blockchains with various block times are targeted and centralized exchanges come into play. Another approach would be a simple setTimeout to a predefined time-interval/delay at which the lifcycle is triggered. Also this is not viable, because it interrupt pending operations in case those take longer than the time-interval/delay.

Solution

This trigger builds on top of a time based delay (defined in milliseconds), by extending it with a debounce and schedule functionality. It basically chains lifecycles, but waits with the callback as long as the user defined delay.

Implementation
