Blockchain API Reference

Blockchain API Examples

Create the bearer_token and store in a file in a secure local directory with 0600 permissions.

Fetch Transactions for an event (v1alpha2)

Blockchain transactions can be fetched from the blockchain endpoint using the Asset’s Event ID as a parameter:

assets/add30235-1424-4fda-840a-d5ef82c4c96f/events/11bf5b37-e0b8-42e0-8dcf-dc8c4aefc000

To fetch all transactions for an Asset’s Events GET the blockchain resource:

curl -v -X GET \
     -H "@$BEARER_TOKEN_FILE" \
     https://app.rkvst.io/archivist/v1alpha2/blockchain/assets/add30235-1424-4fda-840a-d5ef82c4c96f/events/11bf5b3

Depending on the type of proof mechanism used, the response will be:

Simple Hash:

List of Blockchain Transactions associated with an event.

Description: List of Blockchain Transactions associated with an event. If the event’s asset has a proof mechanism of khipu, this will be a list of transactions that compose the event. If the event’s asset has a proof mecahnism of simple hash, this will be a list containing one transaction, that describes the simple hash anchor transaction. If the list is empty, the event has not been anchored yet.
