To prevent changes in a blot in Quill.js, you can disable the editing functionality for that specific blot by setting the readOnly attribute to true. This will prevent users from making any changes to the content within that blot. Here is an example of how you can prevent changes in a blot in Quill.js:

const parchment = Quill.import('parchment');

const ReadOnlyBlot = parchment.Embed.extend({
  // Define the methods to prevent editing
  value() {
    return null;
  },
  insertAt() {},
  deleteAt() {},
  optimize() {},
  prepare() {},
});

// Register the ReadOnlyBlot with Quill
Quill.register(ReadOnlyBlot, true);

// Create a new instance of Quill
const quill = new Quill('#editor', {
  theme: 'snow',
});

// Get the blot you want to make read-only
const blot = quill.getLeaf(0).next;

// Set the readOnly attribute to true for the blot
blot.domNode.setAttribute('readOnly', true);


By setting the readOnly attribute to true for a specific blot, you can prevent users from making any changes to that particular section of the content in Quill.js.
