This directory contains the schemas for the different JSON documents BigchainDB uses.
|
||||
|
||||
The aim is to provide:
|
||||
- a strict definition/documentation of the data structures used in BigchainDB
|
||||
- a language independent tool to validate the structure of incoming/outcoming
|
||||
data (there are several ready to use

[implementations](http://json-schema.org/implementations.html) written in
|

different languages)

You can think of the ``fulfills`` object as a pointer to an output on another transaction: the output that this input is spending/transferring.

A CREATE transaction should have exactly one input. That input can contain one or more ``owners_before``, a ``fulfillment`` (with one signature from each of the owners-before), and the value of ``fulfills`` should be ``null``). A TRANSFER transaction should have at least one input, and the value of ``fulfills`` should not be ``null``.

The list of ``public_keys`` is always the "owners" of the asset at the time the transaction completed, but before the next transaction started.

In a TRANSFER transaction, the sum of the output amounts must be the same as the sum of the outputs that it transfers (i.e. the sum of the input amounts). For example, if a TRANSFER transaction has two outputs, one with ``"amount": "2"`` and one with ``"amount": "3"``, then the sum of the outputs is 5 and so the sum of the outputs-being-transferred must also be 5.
