 This specification explains the `WAKU-SYNC` protocol
 which enables the reconciliation of two sets of message hashes

+## Attack Vectors
 Nodes using `WAKU-SYNC` are fully trusted.
 Message hashes are assumed to be of valid messages received via Waku Relay or Light push.
 
 Further refinements to the protocol are planned
 to reduce the trust level required to operate.

 The following is not part of the specifications but good to know implementation details.

+Ad-hoc syncing can be useful in some cases but continuous periodic sync

 Syncing early and often is the best strategy.
 The default used in nwaku is 5 minutes interval between sync with a range of 1 hour.
 
 ### Range
 We also offset the sync range by 20 seconds in the past.
 The actual start of the sync range is T-01:00:20 and the end T-00:00:20
