Deffect Humanities

Deffect Humanities:

The first project is to share the value of dedication instead of focusing on only seeking profits, Def holders would be deffectvoters to find the right deffect cases for assistance. Deffectfunding is the first decentralized and philanthropic startup capital sharing platform built on a decentralized and transparent mechanism.
Operated on two mechanisms:


The case posting community includes defect startup support and deffect charity, and User is the community that can decide by voting for the cases. The smart contract system will disburse an amount of Def for the following cases:
Startup: A startup is an individual or a technology organization that wants to find investment funds to build up ideas.
Charity: The community is the self-executing case that needs help.
Competency balance: the more def there are, the more decisions there are


A database snapshot is a static, read-only snapshot of an encrypted database on the main net platform.
A database snapshot is a protocol that is concurrent and consistent with the source database at the time the snapshot was created. This means that the snapshot at that point in time captures the state of the source database correctly and concurrently. A database snapshot is always on the same server instance as its source database. When the source database is updated, the snapshot is also updated. Therefore, the longer the database snapshot, the more likely it is to use up all of its available disk space.
Multiple snapshots can exist on a given source database. Each database snapshot will be perpetual.

Overview on features – activities of Snapshot

Database snapshots operate at the data-page level. Before a page in the source database is modified for the first time, the original page is copied from the source database into a snapshot. The snapshot saves the original page, maintaining the existing data records when the snapshot was created. The same process is repeated for each page in first revisions. For the user, the database snapshot usually never changes, because read operations on the database snapshot always access the original data pages, no matter where they are located.
To archive copied original pages, the snapshot uses one or more scattered files. Initially, scattered files are completely empty files, contain no user data and have not been given space for user data on disk. As more and more pages are updated in the database, the size of the file increases.
The following figure illustrates the results of the two updated samples in contrast to the snapshot size. State A reflects the environment in which only 30% of the original pages were updated during the snapshot lifetime. State B reflects an environment in which 80% of the original pages were updated during the snapshot lifetime.

Benefits of database snapshot

Customers may query the database snapshots, thereby, voting based on data at the time of snapshot creation.

Maintaining historical data to generate reports

Snapshot supports extending access to data for users at specific times. For example, you can create a snapshot of the database at the end of a specified period (such as the end of a fiscal quarter) for later reporting. As such, you can run final reports on snapshots. If disk space permits, you can also maintain end-of-term snapshots for as long as you want, allowing for reverse querying of results within these intervals, taking Example: doing team performance survey Charity in Deffect. Protect data from administrative errors.

Reverting to original state

In the event of a user error on the source database, you can revert (back to the original state) of the source database when a snapshot of the given database was created. Loss of data while updating has been controlled and limited since snapshot was born.
