graphene::chain::block_summary_object Class Reference

tracks minimal information about past blocks to implement TaPOSWhen attempting to calculate the validity of a transaction we need to lookup a past block and check its block hash and the time it occurred so we can calculate whether the current transaction is valid and at what time it should expire.

Detailed Description

tracks minimal information about past blocks to implement TaPOS

When attempting to calculate the validity of a transaction we need to lookup a past block and check its block hash and the time it occurred so we can calculate whether the current transaction is valid and at what time it should expire.
