How work with blocks? Maybe divide block to parallel blocks?

Each kind of block has only transactions with FROM or TO in range.

We have 10 nodes, 10 addresses: 0-9

We have 4 group of address:

0,1,2

3,4

5,6,7

8,9

and random 10 transactions:

1 send to 8 30 coins //BEFORE: 1 has 50, 8 has 50; AFTER: 1 has 20, 8 has 80

2 send to 0 20 coins //BEFORE: 2 has 50, 0 has 50; AFTER: 2 has 30, 0 has 70

0 send to 7 40 coins //BEFORE: 0 has 50 or 70, 7 has 50; AFTER: 0 has 30, 7 has 90

5 send to 9 10 coins //BEFORE: 5 has 50, 9 has 50, AFTER: 5 has 40, 9 has 60

9 send to 8 20 coins //BEFORE: 9 has 50 or 60, 8 has 80 or 50; AFTER: 9 has 40, 8 has 100

2 send to 7 10 coins //BEFORE: 2 has 50 or 30, 7 has 50 or 90; AFTER: 2 has 20, 7 has 100

3 send to 1 20 coins //BEFORE: 3 has 50, 1 has 50 or 20; AFTER: 3 has 40, 1 has 40

1 send to 7 10 coins //BEFORE: 1 has 40 or 50, 7 has 50 or 100; AFTER: 1 has 30, 7 has 110

0 send to 4 30 coins //BEFORE: 0 has 50 or 30, 4 has 50; AFTER: 0 has 0, 40 has 80

3 send to 7 20 coins //BEFORE: 3 has 50 or 40, 7 has 50 or 110 AFTER: 3 has 20, 7 has 130

We have 2*4 blocks with 10+(10-common 2) transactions:

parblock FROM or TO = 0,1,2

1 send to 8 30 coins //before 1 has 50, 8, AFTER 50, AFTER 1 has 20, 8 has 80

0 send to 7 40 coins//before 0 has 70 or jeszcze 50, 7 has 50; AFTER 0 has 30, 7 has 90

parblock not FROM but TO = 8.9

This verbose example show decomposition list of transactions to parallel blocks. We have 4 groups and 18 instead 40 summary transactions in all blocks
