Update the procedure of verifying and creating collation #31

Closed hwwhww closed 6 years ago

hwwhww commented 6 years ago

Description

For sharding validator, since we want to remove the SHUFFLING_CYCLE with stateless client, the syncing procedure would be executed more frequently with much lesser execution time.
Verify the collation from the guessing collation head and traceback the deeper collations round by round to get the head collation. In each round, pick collations with scores in range and verify them. Run as many rounds within a certain time.

Sub-tasks

[x] Add get_eligible_proposer function in validator manager contract
[ ] Update validator manager contract after applying stateless client #28
[ ] Implement GUESS_HEAD
[ ] Implement UPDATE_WITNESS(tx, db)
[ ] Implement CREATE_COLLATION(s, cb)
