Understanding the Retrieve Message Container Node

In this quick tutorial, we will cover “Understanding the Retrieve Message Container Node”. The Catenis platform allows you to log content directly to a bitcoin transaction, or if the content is larger than 75 bytes, it logs it to IPFS, inserting the IPFS hash into the bitcoin transaction. As its name implies, the “Retrieve Message Container” node retrieves information about the container object in which a message’s content is recorded.

This node takes as input the ID of the message you wish to retrieve container information for, in String format, and returns a JSON object containing the messages transaction ID, the confirmation status of the Bitcoin transaction, and if the message was stored externally, it also returns the IPFS hash pointer location.

In this video we will cover:

• What is the Message container
• What input is needed to retrieve the message container
• Importing a working Retrieve Message Container Node flow
• Running the flow to see its results

Prerequisite

• A Free Catenis Development account or Production account

• Catenis Flow Pallet installed on Node-RED
• A Catenis Virtual Device configured on Node-RED
• Basic understanding of how to use Node-RED
• Basic understanding of Bitcoin Blockchain concepts
• Basic understanding of IPFS
