A small research about TTF and TTA or Time To Finality, Availability and Reorg Resistance

● An example of why TTF is a thing.
● How does it work for Rollups, L2s, L3s and similar things?
● Node categories with additional insights.
● How long does it take for a rollup transaction to achieve finality with examples.
● A deeper understanding of the Finality in cases with external DA where T2!=T5.
● Returning to shared and decentralised sequencers and why Rollup can’t be faster than DA.
● Centralised Point Failure.
● Time to Reorg Resistance.
● What should be implemented to avoid such things?
