Abstract
This QIP defines a block interlink structure to be used in Quai as described in [1] with few modifications.
Motivation
Interlink structure defined in this QIP will enable proof generation and verification of a transaction inclusion in a Block at a depth for which the light node(SPV client) doesn’t have the state to verify, work based snap sync for faster sync. This requires using only O(log(N)) headers instead of the whole chain history.
