BigchainDB and Smart Contracts
|
|
==============================
|
|
|
|
One can store the source code of any smart contract (i.e. a computer program) in BigchainDB, but BigchainDB won't run arbitrary smart contracts.
|
|
|
|
BigchainDB will run the subset of smart contracts expressible using "crypto-conditions," a subset we like to call "simple contracts." Crypto-conditions are part of the `Interledger Protocol <https://interledger.org/>`_.
|
|
|
|
The owners of an asset can impose conditions on it that must be met for the asset to be transferred to new owners. Examples of possible conditions (crypto-conditions) include:
|
|
|
|
- The current owner must sign the transfer transaction (one which transfers ownership to new owners).
|
|
- Three out of five current owners must sign the transfer transaction.
|
|
- (Shannon and Kelly) or Morgan must sign the transfer transaction.
|
|
|
|
Crypto-conditions can be quite complex if-this-then-that type conditions, where the "this" can be a long boolean expression. Crypto-conditions can't include loops or recursion and are therefore will always run/check in finite time.
|
|
|
|
.. note::
|
|
|
|
We used the word "owners" somewhat loosely above. A more accurate word might be fulfillers, signers, controllers, or transfer-enablers. See BigchainDB Server `issue #626 <https://github.com/bigchaindb/bigchaindb/issues/626>`_.
