The First Block

The first block in every Fluree is automatically written when a new ledger is created. This first block contains a series of system collections and predicates.

These collections include: _collection, _predicate, _auth, _block, and _tx.

These flakes set up the collections and predicates that govern a ledger. You can change these initial system collections, for example to allow for upsert in collections. But, we do not recommend changing these system collections unless you have a good understanding of how they work and potential effects.
