Deleting a block doesn't set the version number to MAX_UINT64, but just increases it by one. This makes sure, that if (in case of a synchronization conflict) the block is reintroduced by another client, this is accepted.

When increasing the version number, don't only look at the version number in the block, but also at the last version number given to it by the current client. Ensure, the new version number is higher than both.

When a client deletes a block, it will never again accept it as a valid block.

* Block versions don't have to be globally nondecreasing, but only per client id. This solves potential synchronization conflicts in a multi-client setting.
* Use cpputils::Serializer and cpputils::Deserializer instead of std::ifstream for storing/loading the block version list

Store own client id into the block next to the version number. This will be used to fix synchronization conflicts where the version number on one clients progresses slower than on another client, but synchronizes later.
