- Hash function
H(.): hash function that may include signature as security requires - Transaction
t: a value submitted by a client of the FBA network that can be independently validated by each node. - Transaction Set
s^v: a set of transactions submitted by clients to nodev. - Node block
b^v: of the form<s^v, H(b^v_prev)>a transaction set and a reference to a previous node block - Master block
B: of the form<s^0, s^1, s^3, ..., s^n>a set of node blocks (at most one per node)
We define B1 < B2 by a total lexicographic order on:
- the number of node-block in each master-block
