[Consensus] Finality #29
Description
Finality is key to reasoning about FIL security and usage in general. It is the point beyond which the chain can be assumed to be stable or final.
It is both a result of other design decisions, and can itself be used as a strategy to help achieve other guarantees.
Depends on
- Weighting function (Null block penalization #61)
- Block Delay (finality simulations #62)
- Randomness Sampling (Consensus Confirmation Time Calc #59)
Construction ideas
- Set finality as more than 50% of power has been expressed below a block
- Set finality as block where EC yields one leader before above event (checkpointing)
Impacts bootstrapping: how does a new miner find which chain to mine on?
