How do i add images in Hyperledger

Question

I am trying to make a registry based on hyperperledger with composer .

1- How to integrate image upload with hyperledger Fabric and Composer and How to create smart contract for the registry

Answer 1

You can not directly add an image to the Hyperledger. To add an image to the Hyperledger Blockchain, you need to first convert the image into a Base64 string. 

You can do the conversion using the following code:

fs.readFileSync(‘yourimageFile.jpg’).toString(‘base64’);

And then when the image is converted to the string, store it on the Blockchain like you would usually store any other string.

Hope this helps!
