How BigchainDB is Good for Asset Registrations & Transfers¶
BigchainDB can store data of any kind (within reason), but it’s designed to be particularly good for storing asset registrations and transfers:
- The fundamental thing that one sends to a BigchainDB cluster, to be checked and stored (if valid), is a transaction, and there are two kinds: CREATE transactions and TRANSFER transactions.
- A CREATE transaction can be use to register any kind of asset (divisible or indivisible), along with arbitrary metadata.
- An asset can have zero, one, or several owners.
- The owners of an asset can specify (crypto-)conditions which must be satisfied by anyone wishing transfer the asset to new owners. For example, a condition might be that at least 3 of the 5 current owners must cryptographically sign a transfer transaction.
- BigchainDB verifies that the conditions have been satisfied as part of checking the validity of transfer transactions. (Moreover, anyone can check that they were satisfied.)
- BigchainDB prevents double-spending of an asset.
- Validated transactions are strongly tamper-resistant; see the page about immutability.
BigchainDB Integration with Other Blockchains¶
BigchainDB works with the Interledger protocol, enabling the transfer of assets between BigchainDB and other blockchains, ledgers, and payment systems.
We’re actively exploring ways that BigchainDB can be used with other blockchains and platforms.
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.
